Company Overview
We are a clinical-stage immunotherapy company developing a growing pipeline of targeted cancer and infectious disease immunotherapies based on our Versamune®, Versamune® plus PDS0301and Infectimune™ T cell-activating platforms and PDS0301 tumor targeting immunocytokine. We believe our targeted immunotherapies have potential to overcome the limitations of current immunotherapy approaches through the activation of the right type, quantity and potency of T cells. Versamune, and Versamune plus PDS0301 for treatments in oncology and Infectimune, for treatments in infectious disease. When paired with an antigen, which is a disease-related protein that is recognizable by the immune system, Versamune and Infectimune have both been shown to induce, in vivo, large quantities of high-quality, highly potent polyfunctional CD4 helper and CD8 killer T cells, a specific sub-type of T cell that is more effective at killing infected or target cells. Infectimune is also designed to promote the induction of disease-specific neutralizing antibodies. Versamune plus PDS0301 enhances the proliferation, potency and longevity of T cells in the tumor microenvironment and works synergistically to overcome tumor immune suppression.
In June 2022, two abstracts were presented at the 2022 American Society of Clinical Oncology Annual Meeting: Abstract number 6041, PDS0101 a novel type 1 interferon and CD8 T cell activating immunotherapy in combination with pembrolizumab in subjects with recurrent/metastatic HPV16-positive squamous cell carcinoma (HNSCC) and Abstract number 2518, Phase 2 evaluation of the combination of PDS0101, M9241 (now PDS0301), and bintrafusp alfa with HPV16 positive malignancies. Also in May 2022, we announced expansion of our VERSATILE-002 clinical trial into Europe and in June 2022, we announced that the U.S. Food and Drug Administration (the “FDA”) had granted Fast Track designation to our lead candidate, PDS0101 in combination with Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab). The FDA’s Fast Track designation is designed to aid in the development and to expedite the review of drug candidate applications that could potentially treat serious or life-threatening conditions. In order to receive Fast Track designation, a clinical candidate must also demonstrate the potential to address an unmet medical need. Treatments granted this designation are given the opportunity to have more frequent meetings with the FDA throughout the entire dug development and review process, with the goal of moving promising new drugs more rapidly through the process. It also provides the opportunity to submit sections of a Biologics License Application (the “BLA”) on a rolling basis, where the FDA may review portions of the NDA as they are received instead of waiting for the entire NDA submission. In addition, Fast Track designated products are eligible for priority review at the time BLA submission. In October 2022, we announced the successful end-of-phase 2 meeting with the FDA including guidance on key elements of the clinical program that will support the submission of a BLA.
In July 2022, we announced the presentation of universal flu vaccine preclinical data for PDS0202 at the 41st American Society of Virology meeting: Abstract number 3733830, Infectimune™ enhances antibodies elicited by COBRA hemagglutinin influenza vaccine.
In November 2022, we announced the presentation of data from two Phase 2 clinical trials at the 37th Annual Meeting for the Society of Immunotherapy of Cancer (SITC): Abstract number 674, IMMUNOCERV, an ongoing Phase 2 trial combining PDS0101, an HPV-specific T cell immunotherapy, with chemotherapy and radiation for treatment of locally advanced cervical cancers and Abstract number 695, Immune correlates associated with clinical benefit in patients with checkpoint refractory HPV-associated malignancies treated with triple combination immunotherapy.
In January 2023, we announced the exclusive global license agreement with Merck KGaA, Darmstadt, Germany for the tumor targeting antibody conjugated IL-12, M9241, which joined our pipeline as PDS0301. PDS0301 is a novel investigational tumor-targeting fusion protein of Interleukin 12 that enhances the proliferation, potency, infiltration and longevity of T cells in the tumor microenvironment and is therefore designed to overcome the limitations of cytokine therapy which today have resulted in high toxicity and limited therapeutic potential. The proprietary combination of Versamune plus PDS0301 is designed to overcome tumor immune suppression utilizing a different mechanism from immune checkpoint inhibitors (ICI). The ownership of both assets we believe will streamline the registrational process and its use. The combination of Versamune® and IL-12 to overcome immune suppression is patented by PDS Biotech. In a Phase 2 National Cancer Institute (NCI)-led clinical trial in ICI refractory patients, the combination of PDS0101 and PDS0301 administered with an investigational bi-functional ICI resulted in a median overall survival of 21 months, which compares favorably to the historical median survival of 3-4 months reported in ICI refractory HPV-positive cancers when treated with ICIs and best reported median survival to date with systemic therapy of 8.2 months in ICI refractory head and neck cancer.
In February 2023, we announced a successful completion of a Type B meeting with the FDA for the triple combination of PDS0101 and PDS0301 with an FDA-approved immune checkpoint inhibitor for the treatment of recurrent/metastatic, ICI refractory head and neck cancer that is positive for the human papilloma virus (HPV) type 16. In recent interactions with the FDA, we confirmed the required contents of a clinical protocol for the potential registrational trial.
In April 2023, we announced that an abstract was accepted for a poster discussion at the 2023 American Society of Clinical Oncology: Abstract Number 6012, Safety and Efficacy of Immune Checkpoint Inhibitor (ICI) Naïve Cohort from Study of PDS0101 and Pembrolizumab in HPV16-Positive Head and Neck Squamous Cell Carcinoma (HNSCC). In addition, the Abstract was selected to be a featured poster to be reviewed by an expert panel in the Head and Neck Cancer Discussion Session.
Clinical Candidate Pipeline
VERSATILE-002: PDS0101 + KEYTRUDA®
In November 2020, our VERSATILE-002 Phase 2 clinical trial evaluating the combination of PDS0101 in combination with Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab) which is the FDA-approved standard of care for first-line treatment of recurrent/ metastatic head and neck cancer commenced. Enrollment in stage 2 of 2 for the ICI naïve arm is almost complete, and enrollment in Stage 1 of the ICI refractory arm is complete. The clinical trial will evaluate the efficacy and safety of this therapeutic combination as a first- and second line treatment in patients with recurrent or metastatic head and neck cancer and high-risk human papillomavirus-16 (HPV16) infection.
In this PDS Biotech-sponsored trial patients whose cancer has returned following initial treatment or spread will be treated with the combination of PDS0101 and KEYTRUDA® to evaluate if the addition of PDS0101 might improve the efficacy reported in published studies of KEYTRUDA® alone. Patients in the trial will receive a total of 5 cycles of combination therapy in the context of standard of care KEYTRUDA® therapy administered every three weeks until disease progression. The primary endpoint of VERSATILE-002 is the objective response rate– or ORR – at six months following initiation of treatment. There are two cohorts in the trial. Cohort 1 is for patients who have yet to be treated with an immune checkpoint inhibitor (ICI naïve) and cohort 2 which consists of patients who have failed immune checkpoint inhibitor therapy (ICI refractory).
In February 2022, we announced we had achieved the preliminary efficacy milestone of at least four or more objective responses of the first 17 patients in the ICI naïve arm that allowed that arm to proceed to full enrollment. We also announced detailed preliminary safety data which showed that the combination is well tolerated without evidence of enhanced or significant toxicity in the first 18 patients in the ICI naïve arm. We have completed enrollment in Stage 1 of the ICI refractory arm and we are waiting for sufficient follow up to conduct the futility analysis.
In June 2022, we announced additional preliminary efficacy and safety data from this trial at the ASCO Annual Meeting (Weiss J et al. J Clin Oncol 40, 2022 (suppl 16; abstr 6041). The abstract provided preliminary data on 19 patients (safety) with available imaging data for 17 of the 19 patients (efficacy). Highlights from the abstract were as follows:
| ● | Confirmed and unconfirmed response rates thus far (tumor shrinkage greater than 30%) seen in 7/17 (41.2%) patients in comparison to the published results of approximately 19% for approved ICIs, used as monotherapy for recurrent or metastatic head and neck cancer, with 2 of the 7 having complete responses (CR) |
| ● | Stable disease (SD) was reported in 6/17 (35.3%) patients, with 4 of the 6 (67%) experiencing tumor shrinkage of less than 30% |
| ● | Clinical efficacy (ORR + SD) was seen in 13/17 (76.5%) patients |
| ● | Progressive/ongoing disease was reported in 4/17 (23.5%) patients |
| ● | Patients had received a median of 4/5 doses of PDS0101 (range 1-5) and 9/35 doses of KEYTRUDA® (range 1-18) |
| ● | There were no treatment-related adverse events greater than or equal to Grade 3 (N=19) |
| ● | No patients required dose interruption or reduction on the combination treatment |
| ● | No patients discontinued the combination treatment |
| ● | At 9 months of follow up (median not yet achieved): |
| | ● | Progression free survival (PFS) rate was 55.2% |
| ● | Overall survival (OS) rate was 87.2% |
| ● | no control or comparative studies have been conducted between ICIs and PDS0101 |
In May 2022, we announced the expansion of this trial into Europe and in June 2022, as described above, we received Fast Track designation from the US FDA for PDS0101 in combination with pembrolizumab.
In August 2022, we announced our independent Data Monitoring Committee (DMC) met and evaluated data from 43 patients and noted there were no Grade 3 or greater treatment-related adverse events attributed to the combination. The DMC recommended continuing the trial with no modifications.
In October 2022, we announced an end-of-phase 2 meeting with the FDA for PDS0101 in combination with KEYTRUDA®. We have currently completed development of the Phase 3 clinical program that will support the submission of a Biologics License Application for PDS0101. We expect to file the amended IND with the FDA during Q3 2023.
In December 2022, we announced completion of the first stage of enrollment in the ICI refractory arm. Cohort follow-up is in progress that will permit a futility analysis to determine progression to stage 2 enrollment.
National Cancer Institute: PDS0101+ M9241 (now PDS0301) +Bintrafusp Alfa
In June 2020, the first patient was dosed under a PDS0101 Cooperative Research and Development Agreement (CRADA), in the NCI led Phase 2 investigator-initiated trial evaluating PDS0101 with an IgG1 IL-12 (M9241), now PDS0301, and M7824 (Bintrafusp alfa), which is owned by EMD Serono (Merck KGaA) in patients with advanced/refractory HPV-positive cancers who have failed prior treatment. In February 2021, we announced that the NCI’s Phase 2 clinical trial of PDS0101 for the treatment of advanced/refractory HPV-positive cancers had achieved its preliminary objective response target in patients naïve to check point inhibitors which allowed for full enrollment of approximately 20 patients in this group. In addition, based on promising results in the ICI naïve arm, the trial was amended to allow enrollment of a separate cohort of ICI-refractory patients for assessment of safety and activity of the triple combination. Preliminary efficacy assessment of the triple combination in this added group of 20 ICI refractory patients has been completed and evaluation of long-term patient survival ongoing.
Preclinical study results arising from this CRADA were published in the Journal for ImmunoTherapy of Cancer,Immunomodulation to enhance the efficacy of an HPV therapeutic vaccine (Journal for ImmunoTherapy of Cancer2020;8:e000612. doi:10.1136/ jitc-2020-000612), and indicate that PDS0101 generated both HPV-specific T cells and an associated antitumor response when used as a monotherapy. When PDS0101 was combined with the two other novel clinical-stage anti-cancer agents, Bintrafusp Alfa and M9241 (which is now owned by us and referred to as PDS0301), the preclinical data suggested that all three therapeutic agents worked synergistically to provide superior tumor T cell responses and subsequent tumor regression when compared to any of the agents alone or the 2-component combinations. The published preclinical data demonstrating powerful activity of the triple combination appears to be corroborated in the Phase 2 trial, and this triple combination could form the basis of a unique platform providing improved cancer treatments across multiple cancers.
In June 2021, at the American Society of Clinical Oncology (ASCO) conference the NCI announced interim data in this trial which included, data in both ICI naïve and refractory patients. In the ICI naïve group 83% (5/6) of patients had an objective response, and 1 subject had achieved a complete response with no evidence of disease. 100% of the ICI naïve patients (8/8) were alive at a median duration of 8 months. In the ICI refractory group 42% (5/12) of patients had an objective response, and 1 subject had achieved a complete response with no evidence of disease. 10/12 (83%) of ICI refractory patients were alive at a median duration of 8 months. An update provided in January 2022 showed as of December 31, 2021, that >40 subjects had been recruited into the trial and 30 HPV16-positive patients had been evaluated. The median survival of all patients (3:1 ICI refractor to naïve) was 12 months and progressing. The historical survival of ICI naïve and ICI refractory advanced HPV-positive cancers when treated with ICI are 7-11 months and 3-4 months, respectively, and best reported median survival to date with systemic therapy of 8.2 months in ICI refractory head and neck cancer.
In June 2022, at the 2022 ASCO Annual Meeting, the NCI provided an update to the preliminary data presented at the 2021 meeting (Strauss J et al. J Clin Oncol 40, 2022 [suppl 16; abstr 2518]). This included data from 30 HPV16-positive patients and highlights were as follows:
| ● | Objective response (OR = >30% tumor reduction) was seen in 88% (7/8) of patients with ICI-naive disease; 4/7 (57%) patients’ responses are ongoing (median 17 months). |
| ● | With ICI refractory patients: PDS0301 dosing appears to affect response rates, with 5/8 (63%) patients receiving PDS0301 at 16.8 mcg/kg achieving an OR compared to 1/14 (7%) patients who received PDS0301 at 8 mcg/kg achieving an OR; 4/6 (67%) patients’ responses are ongoing (median 12 months). |
| ● | Tumor reduction was seen in 45% (10/22) of patients with ICI-refractory disease, including patients receiving high or low dose PDS0301. |
| ● | In ICI refractory patients treated with high or low dose PDS0301, survival outcomes were similar (p=0.96 by Kaplan Meier analysis). At a median of 12 months of follow up 17/22 (77%) of patients were alive. |
| ● | In ICI naïve patients 6/8 (75%) were alive at median 17 months of follow up. |
| ● | Similar OR and survival were seen across all types of HPV16-positive cancers. |
| ● | Preliminary safety data: 13/30 (43%) of patients experienced Grade 3 treatment-related adverse events (AEs), and 2/30 patients (7%) experienced Grade 4 AEs. There were no grade 5 treatment-related AEs. |
| ● | We believe the study results to date strongly suggest, in agreement with the published preclinical studies, that all 3 drugs contribute to the clinical outcomes. |
In September 2022, we announced, in agreement with the NCI, that the ICI refractory patients had been selected as the preferred treatment group in the on-going PDS0101-based triple combination therapy in advanced HPV-positive cancers and the trial was closed to further enrollment given the ICI refractory arm has been fully recruited.
In October 2022, we announced expanded interim data as follows:
| ● | Survival data: 66% (19/29) of HPV16-positive ICI refractory patients in the cohort were alive at a median follow up of 16 months. |
| ● | Safety profile: 48% (24/50) patients experienced Grade 3 treatment-related adverse events (AEs), and 4% (2/50) patients experienced Grade 4 AEs. There were no Grade 3 treatment-related AEs. |
| ● | HPV16-positive ICI naïve patients: 75% (6/8) were alive at a median follow up of 25 months and 38% (3/8) of responders had a complete response. |
In December 2022, we announced expanded interim data as follows:
| ● | Median OS was 21 months in 29 checkpoint inhibitor refractory patients who received the triple combination. The reported historical median OS in patients with ICI refractory disease is 3-4 months seen with checkpoint inhibitors and best reported median survival to date with systemic therapy of 8.2 months in ICI refractory head and neck cancer. |
| ● | In ICI naïve subjects, 75% remain alive at a median follow-up of 27 months. As a result, median OS has not yet been reached. Historically median OS for similar patients with platinum experienced ICI naïve disease is 7-11 months. |
| ● | Objective response rate (ORR) in ICI refractory patients who received the optimal dose of the triple combination is 63% (5/8). In current approaches ORR is reported to be less than 10%. |
| ● | ORR in ICI naïve patients with the triple combination is 88%. In current approaches ORR is reported to be less than 25% with FDA-approved ICIs in HPV-associated cancers. |
| ● | Safety data have not changed since October’s update. 48% (24/50) of patients experienced Grade 3 (moderate) treatment-related adverse events (AEs), and 4% (2/50) patients experienced Grade 4 (severe) AEs, compared with approximately 70% of patients receiving the combination of ICIs and chemotherapy reporting Grade 3 and higher treatment-related AEs. |
In February 2023, we announced the successful completion of a Type B meeting with the FDA for the combination therapy of PDS0101, PDS0301, and an FDA-approved immune checkpoint inhibitor for the treatment of recurrent/metastatic HPV-positive ICI-refractory head and neck cancer. We confirmed the required contents of the study design for a potential registration of the combination.
MD Anderson Cancer Center (IMMUNOCERV): PDS0101+ Chemoradiotherapy
In October 2020, another PDS0101 Phase 2 IIT was initiated with The University of Texas MD Anderson Cancer Center and is actively recruiting patients. This clinical trial is investigating the safety and anti-tumor efficacy of PDS0101 in combination with standard-of-care chemo-radiotherapy, or CRT, and their correlation with critical immunological biomarkers in patients with locally advanced cervical cancer. We believe that Versamune has strong T cell induction with the potential to enhance efficacy of the current standard of care CRT treatment in this indication.
In November 2022, we announced data from this trial was included in a poster presentation at the 2022 SITC Annual Meeting which included the following:
| ● | 9 of the 17 patients had completed a Day 170 post-treatment Positron Emission Tomography, Computed Tomography (PET CT) scan to assess the status of the cancer. This included 78% (7/9) of treated patients with advanced cervical cancer (FIGO stage III or IV). |
| ● | 100% (9/9) of patients treated with the combination of PDS0101 and CRT had an objective response. |
| ● | 89% (8/9) of patients treated with the combination of PDS0101 and CRT demonstrated a complete response (CR) on Day 170 by PET CT. One patient who received 3 of the 5 scheduled doses of PDS0101 showed signs of residual disease. One patient who had a CR died from an event unrelated to either their underlying disease or treatment. |
| ● | 1-year disease-free survival and 1-year overall survival of 89% (8/9) in patients treated with the combination of PDS0101 and CRT. |
| ● | As previously reported, data confirm PDS0101 treatment activates HPV16-specific CD8 T cells. This increase was not seen in patients who did not receive PDS0101. The increase in HPV16-specific T cells generated by the treatment is positively correlated with tumor cell death, suggesting cytotoxic CD8 T cells are important mediators of antigen-specific immunity. |
| ● | The data affirm that PDS0101 activates Type 1 interferon pathway in humans, mimicking the mechanism previously demonstrated in preclinical studies in animal models. |
| ● | Toxicity of PDS0101 remains limited to low-grade local injection site reactions. |
Mayo Clinic: PDS0101 Monotherapy and in combination with KEYTRUDA®
In February 2022, we announced the initiation of an Investigator-Initiated Trial (ITT), MC200710, for PDS0101 alone or in combination with the immune checkpoint inhibitor, KEYTRUDA®, in patients with HPV-associated oropharyngeal cancer (HPV(+)OPSCC) at high risk of recurrence. The trial is being led by Drs. David Routman, Katharine Price, Kathryn Van Abel, and Ashish Chintakuntlawar at Mayo Clinic, a nationally and internationally recognized center of excellence for the treatment of head and neck cancers. We believe that this trial not only broadens our addressable patient population of those affected by the increasing incidence of HPV(+)OPSCC, but also allows us to better understand the activity of PDS0101 alone or in combination with KEYTRUDA® in earlier stages of disease. This trial is currently open for enrollment.
In this trial, treatment will be administered before patients proceed to transoral robotic surgery (TORS) with curative intent. Treatment in this setting is referred to as neoadjuvant treatment. PDS0101 has been shown to induce killer T cells that target and kill HPV-positive cancers, either alone or in combination with ICIs in preclinical studies, and in combination in clinical studies of patients with advanced recurrent/metastatic HPV-associated cancers. This trial will explore whether PDS0101 with or without checkpoint inhibition may increase HPV-specific anti-tumor responses, potentially resulting in tumor shrinkage, pathologic regression, and decreases in circulating tumor DNA (ctDNA).
PDS0102
PDS0102 is an investigational immunotherapy utilizing tumor-associated and immunologically active T cell receptor gamma alternate reading framed protein (TARP) from the NCI. PDS0102 is designed to treat TARP-associated cancers including, acute myeloid leukemia (AML), prostate and breast cancer. In our preclinical work, in the administration of PDS0102, the Versamuine+TARP antigen combination led to the induction of large numbers of tumor targeted killer T cells. In addition, the TARP tumor antigen alone has already been studied at the NCI in men with prostate cancer and been shown to be safe, immunogenic with slowing tumor growth rates (NCT00972309). We are evaluating the next steps in the clinical development of PDS0102 and are seeking nondilutive financings to move the program into human trials.
In April 2020, the above mentioned PDS Biotech-NCI CRADA was expanded beyond PDS0101 to include clinical and preclinical development of PDS0103. PDS0103 is an investigational immune therapy owned by PDS Biotech and designed to treat cancers associated with the mucin-1, or MUC1, oncogenic protein. These include cancers such as ovarian, breast, colorectal and lung cancers. PDS0103 combines Versamune with novel highly immunogenic agonist epitopes of MUC1 developed by the NCI and licensed by PDS. PDS0103 is currently in the tech transfer and clinical scale up and manufacturing stage.
MUC1 is highly expressed in several types of cancer and has been shown to be associated with drug resistance and poor disease prognosis in breast, colorectal, lung and ovarian cancers, for which PDS0103 is being developed. Expression of MUC1 is often associated with poor disease prognosis, due in part to drug resistance. In preclinical studies, and similarly to PDS0101, PDS0103 demonstrated the ability to generate powerful MUC1-specific CD8 killer T cells. In the first quarter of 2022, we held a pre-IND meeting with the FDA on PDS0103 and prepared to submit our IND package in the first half of 2023. However, the actual submission date may potentially be impacted by the allocation of resources to initiate the pivotal trial for PDS0101. Our primary goal is commercialization of PDS0101, and allocation of resources to implement an earlier than planned start of a registrational trial may delay PDS0103 initiation.
Our current pipeline of Versamune based therapies is as follows:
IL-12 Oncology Immunocytokine Pipeline
PDS0301 (formerly known as NHS-IL-12 and M9241) is a novel investigational antibody conjugated (IgG1), tumor-targeting interleukin 12 (IL-12) immune-cytokine that enhances the proliferation, potency and longevity of T cells in the tumor microenvironment. Together with Versamune based immunotherapies PDS0301 works synergistically to overcome tumor immune suppression and to promote a targeted T cell attack against cancers. As with Versamune, PDS0301 is given by a simple subcutaneous injection. Clinical data suggests the addition of PDS0301 to Versamune based immunotherapies may demonstrate significant disease control in advanced cancer patients by shrinking tumors and/or prolonging life.
With the exclusive global license agreement with Merck KGaA, Darmstadt, Germany for PDS0301, we believe we have simplified our registrational pathway for the NCI-led triple combination by owning both PDS0101 and PDS0301 and combining these agents with an FDA approved ICI. PDS0301 has been designed to overcome the limitations of cytokine therapy as explained above, and based on extensive preclinical studies performed at the NCI evaluating PDS0301 as a monotherapy and also in combinations with established standard of care treatments for cancer we believe that PDS0301 has significant potential as a cytokine therapy independent of Versamune. Based on the informative preclinical studies, a number of ITT Phase 2 trials are currently in progress at the NCI, some of which are outlined below:
| • | A Phase II Study Evaluating T-Cell Clonality After Stereotactic Body Radiation Therapy Alone and in Combination with the Immunocytokine M9241(PDS0301) in Localized High and Intermediate Risk Prostate Cancer Treated with Androgen Deprivation Therapy |
| • | A Phase I/II Study of M9241 (PDS0301) in Combination with Docetaxel in Adults with Metastatic Castration Sensitive and Castration Resistant Prostate Cancer |
| • | Phase I/II of 9241 (PDS0301) going forward as a Monotherapy in Advanced Kaposi Sarcoma |
| • | Phase I/II of M9241 (PDS0301) in Combination of with a Histone Deacetylase (HDAC) Inhibitor in ICI refractory MUC1-posiive colon and bladder cancers among others |
We are working closely with the NCI to determine the determine the best pathway forward for the prioritized PDS0301 studies, as well as evaluating the use of PDS0301 in combination with other Versamune based clinical candidates.
Our current pipeline of antibody conjugated PDS0301 based therapies is as follows:
Infectimune Development Strategy
We believe that the key differentiating attributes of the Infectimune platform technology are strong induction of CD8 and CD4 T cells as well as antibodies which can be leveraged to improve treatment and preventive options in several infectious disease indications. In January 2022, we announced preclinical data on our universal flu program sponsored by the National Institute of Allergy and Infectious Disease (NIAID) demonstrating the potential of the Infectimune technology with computationally designed influenza proteins developed by the laboratory of Dr. Ted Ross at the University of Georgia to generate broadly protective anti-influenza immune responses across multiple strains of influenza. This data has provided a unique opportunity to highlight Infectimune’s potentially transformative utility in the development of more broadly effective and longer lasting protective vaccines. Current preventive and prophylactic vaccine approaches and technologies predominantly focus on creating strong induction of antibody responses. However, the induction of T cell responses, in addition to antibody responses, provides more durable and broad protection against infectious diseases.
Based on the promising data recently announced with the universal seasonal flu vaccine and the current focus of the NIAID in developing more effective flu vaccines, we have decided to opportunistically focus our near-term infectious disease activities to align with the interests of the NIAID Collaborative Influenza Vaccine Innovation Centers (CIVICs) program. This will involve development of a universal seasonal flu vaccine and the potential development of a universal pandemic influenza vaccine based on similar computationally designed antigens as have shown promise with Infectimune.
In July 2022, we announced the presentation of universal flu vaccine preclinical data for PDS0202 at the 41st American Society of Virology meeting: Abstract number 3733830, Infectimune enhances antibodies elicited by COBRA hemagglutinin influenza vaccine. We are evaluating the next steps in the clinical development and funding for PDS0202.
The results for Infectimune based PDS0202 and PDS0203 vaccines were published in two separate articles in the peer reviewed journal Viruses in February 2023: 1. preclinical studies demonstrating complete protection against sickness after lethal challenge with live SARS-CoV-2 or influenza viruses (Gandhapudi SK et al. Viruses 2023, 15, 432) and 2. Dramatically enhanced CD4 T cell responses to recombinant influenza proteins compared to leading commercial vaccine adjuvants (Henson TR et al. Viruses 2023, 15, 538).
Our current pipeline of Versamune and Infectimune based therapies is as follows:
We have never been profitable and have incurred net losses in each year since inception. Our net losses were $9.7 million, and $8.5 million for the three months ended March 31, 2023 and 2022, respectively. As of March 31, 2023, we had an accumulated deficit of $111.2 million. Substantially all of our net losses have resulted from costs incurred in connection with our research and development programs and from general and administrative costs associated with these operations.
As of March 31, 2023, we had $65.2 million in cash and cash equivalents.
Our future funding requirements will depend on many factors, including the following:
| ● | the timing and costs of our planned oncology and infectious disease clinical trials; |
| ● | the timing and costs of our planned preclinical studies of our Immuno-oncology and vaccine clinical candidates; |
| ● | the outcome, timing and costs of seeking regulatory approvals; |
| ● | the terms and timing of any future collaborations, licensing, consulting or other arrangements that we may enter into; |
| ● | the amount and timing of any payments we may be required to make in connection with the licensing, filing, prosecution, maintenance, defense and enforcement of any patents or patent applications or other intellectual property rights; and |
| ● | the extent to which we license or acquire other products and technologies. |
SELECTED FINANCIAL OPERATIONS OVERVIEW
Revenue
We have not generated any revenues from commercial product sales and do not expect to generate any such revenue in the near future. We may generate revenue in the future from a combination of research and development payments, license fees and other upfront payments or milestone payments.
Research and Development Expenses
Research and development expenses include employee-related expenses, licensing fees to use certain technology in our research and development projects, costs of acquiring, developing and manufacturing clinical trial materials, as well as fees paid to consultants and various entities that perform certain research and testing on our behalf. Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations or information provided by vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the consolidated financial statements as prepaid or accrued expenses. Costs incurred in connection with research and development activities are expensed as incurred.
We expect that our research and development expenses will increase significantly over the next several years as we advance our Versamune based immuno-oncology or Infectimune based infectious disease candidates into and through clinical trials, pursue regulatory approval of our investigational candidates and prepare for a possible commercial launch, all of which will also require a significant investment in contract and internal manufacturing and inventory related costs.
The process of conducting human clinical trials necessary to obtain regulatory approval is costly and time consuming. We may never succeed in achieving marketing approval. The probability of successful commercialization of our drug candidates may be affected by numerous factors, including clinical data obtained in future trials, competition, manufacturing capability and commercial viability. As a result, we are unable to determine the duration and completion costs of our research and development projects or when and to what extent we will generate revenue from the commercialization and sale of any of our clinical candidates.
Results of Operations
The following table summarizes the results of our operations for the three months ended March 31, 2023 and 2022:
| | | Three Months Ended March 31, | | | Increase | |

| Net loss and comprehensive loss | | $ | (9,660 | ) | | $ | (8,473 | ) | | $ | (1,187 | ) | | | 14 | % |
Research and Development Expenses
Research and development (R&D) expenses increased to $5.8 million for the three months ended March 31, 2023 from $5.2 million for the three months ended March 31, 2023. The increase of $0.6 million in 2023 was primarily attributable to an increase of $0.2 million in clinical studies and medical affairs, $0.8 million in personnel costs and $0.1 million in professional fees offset by a decrease of $0.5 million manufacturing.
General and Administrative Expenses
General and administrative expenses increased to $3.6 million for the three months ended March 31, 2023 from $3.3 million for the three months ended March 31, 2022. The increase of $0.3 million is primarily attributable to an increase of $0.8 million in personnel costs offset by a decrease of $0.5 million in professional fees.
Liquidity and Capital Resources
In April 2022, we received approximately $1.2 million from the net sale of tax benefits to an unrelated, profitable New Jersey corporation pursuant our participation in the New Jersey Technology Business Tax Certificate Transfer NOL program for tax year 2020.
In August 2022, we filed a shelf registration statement, or the 2022 Shelf Registration Statement, with the SEC for the issuance of common stock, preferred stock, warrants, rights, debt securities, and units, up to an aggregate amount of $150 million, $50 million of which covers the offer, issuance and sale by us of our common stock under the Sales Agreement (as discussed below). The 2022 Shelf Registration Statement was declared effective on September 2, 2022.
In August 2022, we entered into an At Market Issuance Sales Agreement, or the Sales Agreement, with B. Riley Securities, Inc. and BTIG, LLC, each an Agent and collectively the Agents, with respect to an at-the-market offering program under which we may offer and sell, from time to time at our sole discretion, shares of our common stock, having an aggregate offering price of up to $50 million, or the Placement Shares, through or to the Agents, as sales agents or principals. Upon delivery of a placement notice and subject to the terms and conditions of the Sales Agreement, the Agents may sell the Placement Shares by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act of 1933, as amended, including, without limitation, sales made through The Nasdaq Capital Market or on any other existing trading market for our common stock. The Agents will use commercially reasonable efforts to sell the Placement Shares from time to time, based upon our instructions (including any price, time or size limits or other customary parameters or conditions we may impose). We will pay the Agents a commission equal to three percent (3%) of the gross sales proceeds of any Placement Shares sold through the Agents under the Sales Agreement, and also has provided the Agents with customary indemnification and contribution rights. We are not obligated to make any sales of our common stock under the Sales Agreement. The offering of Placement Shares pursuant to the Sales Agreement will terminate upon the earlier of (i) the sale of all Placement Shares subject to the Sales Agreement or (ii) termination of the Sales Agreement in accordance with its terms. For the year ended December 31, 2022, we sold 1,238,491 shares of our common stock with a net value of $9.9 million pursuant to the Sales Agreement. During the quarter ended March 31, 2023, we sold 553,293 shares of our common stock with a net value of $4.6 million pursuant to the Sales Agreement.
In August 2022, we entered into a venture loan and security agreement, or the Loan and Security Agreement, with Horizon Technology Finance Corporation, as lender and collateral agent for itself and the other lenders. The Loan and Security Agreement provides for the following 6 separate and independent term loans: (a) a term loan in the amount of $7,500,000, or Loan A, (b) a term loan in the amount of $10,000,000, or Loan B, (c) a term loan in the amount of $3,750,000, or Loan C, (d) a term loan in the amount of $3,750,000, or Loan D, (e) a term loan in the amount of $5,000,000, or Loan E, and (f) a term loan in the amount of $5,000,000, or Loan F, (with each of Loan A, Loan B, Loan C, Loan D, Loan E, and Loan F, individually a Loan and, collectively, the Loans). Loan A, Loan B, Loan C, and Loan D were delivered to us on August 24, 2022. Loan E and Loan F are uncommitted Loans that may be advanced by the lenders upon their discretion prior to July 31, 2023 upon the satisfaction of certain agreed upon conditions precedent. We may only use the proceeds of the Loans for working capital or general corporate purposes. Each Loan matures on the 48-month anniversary following the applicable funding date unless accelerated pursuant to agreed upon events of default. The principal balance of each Loan bears a floating interest. The interest rate is calculated initially and, thereafter, each calendar month as the sum of (a) the per annum rate of interest from time to time published in The Wall Street Journal as contemplated by the Loan and Security Agreement, or any successor publication thereto, as the “prime rate” then in effect, plus (b) 5.75%; provided that, in the event such rate of interest is less than 4.00%, such rate shall be deemed to be 4.00% for purposes of calculating the interest rate.
Interest is payable on a monthly basis based on each Loan principal amount outstanding the preceding month. We, at our option upon at least ten (10) business days’ written notice to the lenders, may prepay all (and not less than all) of the outstanding Loan by simultaneously paying to each lender an amount equal to (i) any accrued and unpaid interest on the outstanding principal balance of the Loans; plus (ii) an amount equal to (A) if such Loan is prepaid on or before the Loan Amortization Date (as defined in the Loan and Security Agreement) applicable to such Loan, 3% of the then outstanding principal balance of such Loan, (B) if such Loan is prepaid after the Loan Amortization Date applicable to such Loan, but on or before the date that is 12 months after such Loan Amortization Date, 2% of the then outstanding principal balance of such Loan, or (C) if such Loan is prepaid more than 12 months after the Loan Amortization Date but prior to the stated maturity date applicable to such Loan, 1% of the then outstanding principal balance of such Loan; plus (iii) the outstanding principal balance of such Loan; plus (iv) all other sums, if any, that shall have become due and payable thereunder. No prepayment premium will be applied to any outstanding balance of any Loan paid on the stated maturity date.
In connection with the Loan and Security Agreement, we issued Horizon Technology Finance Corporation and Powerscourt Investments XXV, LP warrants to purchase an aggregate total of 381,625 shares of our common stock at an initial exercise price of $3.6685 per share. Each warrant is classified as equity and is exercisable at any time for a period beginning on the date of grant and ending on the earlier of (A) 10 years from the date of grant, and (B) the closing of (A) (i) the sale, lease, exchange, conveyance or other disposition of all or substantially all of the our property or business, or (ii) its merger into or consolidation with any other corporation (other than a wholly-owned subsidiary of the Company), or any transaction (including a merger or other reorganization) or series of related transactions, in which more than 50% of the voting power of the Company is disposed of, in each case, for cash or for marketable securities meeting certain requirements as described in the applicable warrants. The key assumptions used in Black-Scholes option pricing model were (i) expected term of 10 years, (ii) a risk-free rate of 3.11%, (iii) expected volatility of 93.8%, and (iv) no estimated dividend yield.
In April 2023, we received approximately $1.4 million from the net sale of tax benefits to an unrelated, profitable New Jersey corporation pursuant our participation in the New Jersey Technology Business Tax Certificate Transfer NOL program for tax year 2021.
As of March 31, 2023, we had $65.2 million in cash and cash equivalents. Our primary uses of cash are to fund operating expenses, primarily research and development expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable and accrued expenses.
We evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the filing of this Quarterly Report on Form 10-Q. Based on such evaluation and our current plans, which are subject to change, management believes that our existing cash and cash equivalents as of March 31, 2023 will be sufficient to satisfy our operating cash needs into the third quarter of 2024.
We plan to continue to fund our operations and capital funding needs through equity and/or debt financings. However, we cannot be certain that additional financing will be available when needed or that, if available, financing will be obtained on terms favorable to us or our existing stockholders. We may also enter into government funding programs and consider selectively partnering for clinical development and commercialization. The sale of additional equity would result in additional dilution to our stockholders. Incurring debt financing would result in debt service obligations, and the instruments governing such debt could provide for operating and financing covenants that would restrict our operations. If we are unable to raise additional capital in sufficient amounts or on acceptable terms, we may be required to delay, limit, reduce, or terminate our clinical development or future commercialization efforts or grant rights to develop and market immunotherapies that we would otherwise prefer to develop and market ourselves. Any of these actions could harm our business, results of operations and prospects.
Cash Flows
The following table shows a summary of our cash flows for each of the periods indicated (in thousands):
| | | Three Months Ended March 31, | |
| | | 2023 | | | 2022 | |
Net cash used in operating activities | | $ | (13,189 | ) | | $ | (6,369 | ) |
| Net cash provided by financing activities | | | 4,568 | | | | 7 | |
| Net decrease in cash and cash equivalents | | $ | (8,621 | ) | | $ | (6,362 | ) |
Net Cash Used in Operating Activities
Net cash used in operating activities was $13.2 million and $6.4 million for the three months ended March 31, 2023 and 2022, respectively. The increase in net cash used in operating activities of $6.8 million was primarily due to an increase in net loss of $1.2 million, reduced by the increase in the non-cash stock-based compensation expense of $1.0 million, offset by changes in the timing of working capital requirements, including changes in prepaid expenses and other assets, accrued expenses and accounts payable.
Net Cash Provided by Financing Activities
Net cash provided by financing activities for the three months ended March 31, 2023 was due to the receipt of net proceeds of $4.6 million due to the sale of common stock under the Sales Agreement.
Operating Capital Requirements
To date, we have not generated any product revenue. We do not know when, or if, we will generate any product revenue and we do not expect to generate significant product revenue unless and until we obtain regulatory approval and commercialize one of our current or future product candidates. We anticipate that we will continue to generate losses for the foreseeable future, and we expect the losses to increase as we continue the development of, and seek regulatory approvals for, our tablet vaccine candidates, and begin to commercialize any approved vaccine candidates. We are subject to all of the risks incident to the development of new products, and may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may harm our business. We expect to incur additional costs associated with operating as a public company and anticipate that we will need substantial additional funding in connection with our continuing operations.
We evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the filing of this Quarterly Report. Our budgeted cash requirements in 2023 and beyond include expenses related to continuing development and clinical studies. We believe that our existing cash and cash equivalents as of March 31, 2023 are sufficient to continue operations and research and development programs into the third quarter of 2024. Until we can generate significant cash from our operations, we expect to continue to fund our operations with available financial resources. These financial resources may not be adequate to sustain our operations.
We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all of our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:
| ● | the initiation, progress, timing, costs and results of our planned clinical trials; |
| ● | the effects of health epidemics, pandemics, or outbreaks of infectious diseases, on our business operations, financial condition, results of operations and cash flows; |
| ● | the outcome, timing and cost of meeting regulatory requirements established by the U.S. Food and Drug Administration, or FDA, the European Medicines Agency, or EMA, and other comparable foreign regulatory authorities; |
| ● | the cost of filing, prosecuting, defending and enforcing our patent claims and other intellectual property rights; |
| ● | the cost of defending potential intellectual property disputes, including patent infringement actions brought by third parties against us now or in the future; |
| ● | the effect of competing technological and market developments; |
| ● | the cost of establishing sales, marketing and distribution capabilities in regions where we choose to commercialize our products on our own; and |
| ● | the initiation, progress, timing and results of our commercialization of our clinical candidates, if approved, for commercial sale. |
Please see the section titled “Risk Factors” elsewhere in the Quarterly Report and Annual Report for additional risks associated with our operations.
Purchase Commitments
We have no material non-cancelable purchase commitments with service providers as we have generally contracted on a cancelable, purchase order basis.
Critical Accounting Policies and Estimates
Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. GAAP. Our accounting policies are more fully described in Note 2 to the consolidated financial statements included in this Quarterly Report on Form 10-Q. As described in Note 2, the preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenue generated and expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Estimates are assessed each period and updated to reflect current information. Actual results may differ from these estimates under different assumptions or conditions. We believe that the discussion in our management’s discussion and analysis addresses our most critical accounting policies, which are those that are most important to the portrayal of our financial condition and results of operations and require management’s most difficult, subjective and complex judgments.
There have been no material changes to our critical accounting policies and estimates during the three months ended March 31, 2023 from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022.
Off-Balance Sheet Arrangements
We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.
Smaller Reporting Company
As of January 1, 2021, we were no longer an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. However, we remain a “smaller reporting company,” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended. We will cease to be a smaller reporting company if we have a non-affiliate public float in excess of $250 million and annual revenues in excess of $100 million, or a non-affiliate public float in excess of $700 million, determined on an annual basis. As a smaller reporting company, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not smaller reporting companies. We will continue to take advantage of some or all of the available exemptions.
| ITEM 3: | QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK |
We are exposed to market risks in the ordinary course of our business and from changes in the interest rate on our debt borrowings. These market risks are principally limited to interest rate fluctuations. As of March 31, 2023, our cash equivalents consisted of bank deposits and money market accounts and our debt is a variable interest rate instrument. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. The primary objective of our investment activities is to preserve principal and liquidity while maximizing income without significantly increasing risk. We do not enter into investments for trading or speculative purposes. Due to the short-term nature of our investment portfolio and debt agreement, we do not believe an immediate 100 basis point increase in interest rates would have a material effect on the fair market value of our portfolio, and, accordingly, we do not expect our operating results or cash flows to be materially affected by a sudden change in market interest rates.
Inflation generally affects us by increasing our cost of labor and pricing of contracts. We do not believe that inflation has had a material effect on our business, financial condition, or results of operations during the three months ended March 31, 2023.
| ITEM 4: | CONTROLS AND PROCEDURES |
Evaluation of Disclosure Controls and Procedures
An evaluation was carried out, under the supervision of and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15 (e)) under the Securities Exchange Act of 1934, or the Exchange Act, as of the end of the period covered by this report. Based on the evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures are effective to ensure that the information required to be disclosed by us in the reports we file or submit under the Exchange Act was recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) identified in connection with the evaluation identified above that occurred during the quarter ended March 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
| PART II. | OTHER INFORMATION |
The information in Note 9 to the Condensed Consolidated Financial Statements contained in Part I, Item 1 of this Quarterly Report on Form 10-Q is incorporated herein by reference. There are no matters which constitute material pending legal proceedings to which we are a party other than those incorporated into this item by reference from Note 9 to our Condensed Consolidated Financial Statements for the quarter ended March 31, 2023 contained in this Quarterly Report on Form 10-Q.
There have been no material changes from our risk factors as previously reported in our Annual Report on Form 10-K for the year ended December 31, 2022. However, any investment in our business involves a high degree of risk. Before making an investment decision, you should carefully consider the information we include in this Quarterly Report on Form 10-Q, including our unaudited interim condensed consolidated financial statements and accompanying notes, our Annual Report on Form 10-K for the year ended December 31, 2022 filed on March 28, 2023, including our financial statements and related notes contained therein, and the additional information in the other reports we file with the Securities and Exchange Commission. These risks may result in material harm to our business and our financial condition and results of operations. In this event, the market price of our common stock may decline and you could lose part or all of your investment. Additional risks that we currently believe are immaterial may also impair our business operations. Our business, financial conditions and future prospects and the trading price of our common stock could be harmed as a result of any of these risks.
| ITEM 2. | UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS |
There were no unregistered sales of the Company’s equity securities during the three months ended March 31, 2023.
| ITEM 3. | DEFAULTS UPON SENIOR SECURITIES |
None.
| ITEM 4. | MINE SAFETY DISCLOSURES |
Not applicable.
None.
