Vincerx Pharma Reports Fourth Quarter and Full Year 2023 Financial Results and Corporate Update

VIP236, first-in-class small molecule-drug conjugate (SMDC), preliminary Phase 1 data and update on pipeline progress will be presented by management at a virtual investor event on April 8 at 2:00 PM PT

Phase 1 trial ongoing for VIP943, a best-in-class anti-CD123 antibody-drug conjugate (ADC); preliminary data anticipated on or around the 2024 European Hematology Association (EHA) Annual Meeting; in addition, pharmacokinetic data will be shared at the 2024 American Association of Cancer Research (AACR) Annual Meeting

Expected cash runway into early Q3 2024

PALO ALTO, Calif., March 29, 2024 – Vincerx Pharma, Inc. (Nasdaq: VINC), a biopharmaceutical company aspiring to address the unmet medical needs of patients with cancer through paradigm-shifting therapeutics, today reported financial results for the fourth quarter and full year ended December 31, 2023, and provided a corporate update.

“The last calendar year was pivotal for Vincerx,” said Ahmed Hamdy, M.D., Chief Executive Officer. “Having progressed three clinical programs, including VIP236 and VIP943, both developed with our VersAptx^TM platform, and enitociclib, we firmly established ourselves as a clinical-stage cancer therapeutics company with novel product candidates that aim to improve safety and efficacy over traditional chemotherapy.”

Raquel Izumi, Ph.D., Chief Operations Officer, added, “VIP236, our first-in-class SMDC, is in a Phase 1 dose-escalation trial for advanced and metastatic solid tumors. To date, we have dosed 20 patients across two dosing schedules and results from the once every 3-week dosing schedule continue to show a strong safety profile with dose-dependent clinical activity. We are excited to share more details regarding the preliminary Phase 1 data during the 2024 AACR Annual Meeting.”

Dr. Izumi continued, “VIP943, our best-in-class anti-CD123 ADC, is in a Phase 1 dose-escalation trial in hematologic malignancies. Enrollment in the third cohort is underway with a total of 9 patients dosed. Preliminary pharmacokinetic data from the first two cohorts show very little payload in circulation, which aligns with the favorable safety profile observed in nonhuman primates in our preclinical studies. We look forward to sharing pharmacokinetic data for VIP943 during AACR and more details regarding the preliminary Phase 1 data on or around EHA. Enitociclib, our highly selective CDK9 inhibitor, in a Phase 1 dose-escalation study with the National Institutes of Health (NIH), has signaled encouraging efficacy in Phase 1 combination studies in peripheral T-cell lymphoma (PTCL) and double-hit B-cell lymphoma (DLBCL). Earlier this year, we reported partial responses at doses below expected efficacy levels, highlighting the drugs synergistic potential with other treatments.”

Dr. Hamdy concluded, “We entered 2024 with strong momentum and remain focused on aggressively advancing our programs and maximizing the value of our next-generation VersAptx platform.”

FOURTH QUARTER AND FULL YEAR 2023 CLINICAL PROGRAM HIGHLIGHTS

VersAptx^™ Platform

• VersAptx is Vincerx’s versatile and adaptable, next-generation bioconjugation platform. The modular nature of this platform enables the combination of different targeting, linker, and payload technologies to develop bespoke bioconjugates to address different cancer biologies.

• Recent preclinical data demonstrated the ability of our legumain linker + KSPi payload with CellTrapper effector chemistry to enhance the potency of TRODELVY^® and ENHERTU^®, two marketed ADCs, by conjugating TRODELVY’s TROP2 and ENHERTU’s HER2 antibodies with our effector chemistry. The results of this study demonstrated a significant improvement in the potency of both drugs, with TRODELVY potency amplified by a factor of 20 and ENHERTU potency by a factor of 8.

• Vincerx published a manuscript in Frontiers in Pharmacology titled, “Neutrophil elastase as a versatile cleavage enzyme for activation of α_vb₃ integrin-targeted small molecule drug conjugates with different payload classes in the tumor microenvironment.”

• Vincerx presented a preclinical poster at the 2023 AACR Annual Meeting demonstrating the promise of VIP924, a first-in-class CXCR5-targeted ADC from the VersAptx platform.

VIP236

• VIP236 is a α_vb₃ SMDC conjugated to an optimized camptothecin (CPT) from the VersAptx platform. VIP236 is a first-in-class product candidate designed to deliver its optimized CPT payload directly to tumor tissues to overcome the chemotherapy-related side effects and transporter liabilities of this well-established class of anticancer drugs. Preclinical studies have shown 11 times more optimized CPT is delivered to the cancerous tissues than found circulating in the blood. Additionally, the active component of VIP236 is designed to bypass cancer resistance mechanisms.

• The favorable characteristics of VIP236, including improved linker attachment, stable solubility, and tumor-specific payload release, were featured in a peer-reviewed publication titled, “Unleashing the Potential of Camptothecin: Exploring Innovative Strategies for Structural Modification and Therapeutic Advancements,” by Zheng Chen in the March 14, 2024 issue of Journal of Medicinal Chemistry.

• To date, the VIP236 Phase 1 dose-escalation trial (NTC05371054) has enrolled 20 patients with advanced or metastatic cancer unresponsive to standard therapies.

• Vincerx will present more details around the preliminary Phase 1 data at the upcoming 2024 AACR Annual Meeting, accompanied by a virtual investor event to review the data and provide a pipeline update on April 8 at 2:00 PM PT. The event can be accessed through the Investors Page on the Vincerx website.

VIP943

• VIP943 is a novel CD123-targeted antibody-drug conjugate (ADC) from the VersAptx platform.

• In August 2023, Vincerx received IND clearance for a Phase 1 dose-escalation trial of VIP943 in relapsed/refractory acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and B-cell acute lymphoblastic leukemia (B-ALL) (NCT06034275).

• In September 2023, Vincerx announced the dosing of its first patient in that study.

• Enrollment in the third cohort is underway, with a total of 9 patients dosed. Preliminary pharmacokinetic results continue to show very little payload circulating in the blood, validating the favorable safety profile observed in nonhuman primates in preclinical studies.

• Vincerx will present more details regarding the preliminary Phase 1 data for VIP943 on or around the 2024 EHA Annual Meeting.

Enitociclib

• Enitociclib is a highly selective CDK9 inhibitor designed to block the activation of RNA polymerase II, leading to the reduction of oncogenes MYC and MCL1.

• In 2023, Vincerx presented preclinical data supporting the continued advancement of enitociclib at multiple medical congresses. Vincerx also published a manuscript titled, “Enitociclib, a Selective CDK9 Inhibitor, Induces Complete Regression of MYC+ Lymphoma by Downregulation of RNA Polymerase II Mediated Transcription” in Cancer Research Communications, an AACR journal.

• Enitociclib is currently in a Phase 1 dose-escalation trial (NTC05371054) evaluating the combination of enitociclib, venetoclax, and prednisone in DLBCL and PTCL. This trial is being conducted in collaboration with the NIH.

• Earlier this year, Vincerx announced that 2 out of 3 patients with PTCL had a partial response (PR). The first patient saw a 91% reduction in their tumor burden, while the second patient saw an 86% reduction in pulmonary lesions and resolution of skin lesions. In addition, 1 out of 2 patients with DH-DLBCL had a PR after one cycle of treatment, seeing an 80% reduction in tumor burden. These responses occurred at doses below expected efficacy levels.

VIP924

• VIP924 is a first-in-class CXCR5-targeted ADC from the VersAptx platform.

• Vincerx presented preclinical data at the 2023 AACR Annual Meeting demonstrating significant activity in patient-derived xenograft (PDX) lymphoma mouse models.

• Vincerx shared preclinical data at the 2023 ASH Annual Meeting showing superior activity and safety compared with commercially available B-cell targeted ADCs.

• IND application anticipated in late 2025 or early 2026, pending funding.

FOURTH QUARTER AND FULL YEAR 2023 FINANCIAL RESULTS

• Vincerx had $12.8 million in cash and cash equivalents as of December 31, 2023, as compared to $52.5 million in cash, cash equivalents and marketable securities as of December 31, 2022. Based on its current business plans and assumptions, Vincerx believes its available capital will be sufficient to meet its operating requirements into early third quarter of 2024.

• Research and development (R&D) expenses for the fourth quarter and full year 2023 were $3.7 million and $29.0 million, respectively, as compared to $11.5 million and $49.8 million, respectively, for each of the same periods in 2022. The year over year decrease of approximately $20.9 million is primarily the result of decreases in third party service and supplier expenses, including manufacturing services associated with our ADC program of approximately $9.7 million and clinical services of approximately $2.6 million, as well as decreases in expenses related to headcount, including declines in stock-based compensation expense of approximately $3.3 million and employee salaries of approximately $3.1 million as a result of our headcount reduction in June 2022.

• General and administrative (G&A) expenses for the fourth quarter and full year 2023 were $1.8 million and $13.6 million, respectively, as compared to $4.0 million and $18.9 million for the same periods in 2022. The year over year decrease of approximately $5.2 million was primarily driven by decreases in stock-based compensation expense of $2.8 million, professional services of $1.4 million, and a decrease in expenses related to headcount of $0.7 million.

• For the fourth quarter and full year 2023, Vincerx reported a net loss of $4.9 million, or $0.23 per share, and a net loss of $40.2 million, or $1.89 per share, respectively. For the fourth quarter and full year 2022, Vincerx reported a net loss of $13.8 million, or $0.65 per share, and a net loss of $63.0 million, or $3.00 per share, respectively.
