NexImmune Reports Fiscal Year 2020 Financial Results and Recent Updates

• In 2020, advanced two product candidates into Phase 1/2 clinical trials while strengthening Board of Directors and management team

• Completed successful $126M initial public offering (IPO) in February 2021 to fund continuing operations through the second quarter of 2022

• Additional clinical and preclinical data anticipated in the second half of 2021

GAITHERSBURG, MD – March 31, 2021 – NexImmune, Inc. (Nasdaq: NEXI), a clinical-stage biotechnology company developing a novel approach to immunotherapy designed to orchestrate a targeted immune response by directing the function of antigen-specific T cells, today reported its financial results for 2020 and highlighted recent corporate accomplishments.

“2020 was a transformational year for NexImmune,” said Scott Carmer, Chief Executive Officer. “Our first two programs, NEXI-001 and NEXI-002, entered Phase 1/2 clinical trials and successfully enrolled patients throughout the year despite the COVID-19 pandemic. We were very pleased to have initial data from our first cohort of patients in the NEXI-001 trial accepted for oral presentation at the ASH annual meeting in December. In addition, we strengthened our management team, scientific advisory board and Board of Directors with the addition of several industry-leading scientists and executives. All of these advancements contributed to our successful IPO in February, 2021.”

Mr. Carmer added, “With a strong cash position from the completion of our IPO, we are focused on driving our current clinical trials toward completion, and to accelerating ongoing development of our AIM ACT product pipeline and platform technology. This work will concentrate on clinical programs targeting solid tumors and IND-enabling pre-clinical experiments to support the initial application of our ‘AIM Injectable’ formulation, respectively. In developing our proprietary AIM nanoparticle technology, our mission is to transform cell-mediated immunotherapy for the benefit of patients facing a number of difficult-to-treat diseases.”

Select corporate highlights

On February 17, 2021, NexImmune completed a successful IPO and raised gross proceeds of $126M. The IPO was oversubscribed and priced at the top of the range.

During January 2021, NexImmune announced the appointments of Robert Knight, MD as Chief Medical Officer; Jerome Zeldis, MD, PhD as Executive Vice President, Research and Devopment; Jeffery Weber, MD, PhD as Chief Scientific Advisor and Scientific Advisory Board Chair; and Grant Verstandig as a member of the Board of Directors.

On December 7, 2020, lead investigators for the Company’s ongoing Phase 1/2 clinical trial evaluating NEXI-001 provided an oral presentation at the 62^nd American Society of Hematology (ASH) Annual Meeting and Exposition that highlighted initial results from the first five patients treated. Initial data demonstrated early signs of safety, tolerability and robust immune responses in acute myeloid leukemia (AML) patients with relapsed disease after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

On October 6, 2020, NexImmmune announced dosing of the first patient in its Phase 1/2 trial of NEXI-002 for the treatment of patients with relapsed and/or refractory multiple myeloma that had failed at least three lines of prior therapy.

NEXI-001 and NEXI-002 are both in Phase 1/2 clincal trials. The company expects to share preliminary data from the initial safety cohorts of each trial at a conference in Q2 2021, with more complete results for each trial at the end of Q4 2021.

Select financial highlights

Cash and cash equivalents for the company as of December 31, 2020 were $5.0M, compared to $9.1M at December 31, 2019. Based upon its current operating plans and cash and cash equivalents, including the net proceeds from the IPO, the Company expects to have sufficient capital to fund its operating expenses and capital expenditure requirements through the second quarter of 2022.

Research and development expenses were $17.8M in 2020, compared to $15.2M in 2019. The increase in R&D expenses were mainly attributable to costs for the two clinical trials as well as personnel-related expenses driven by increased headcount, offset partially by reduced preclinical and regulatory-related spending.

General and administrative expenses were $10.0M and $5.7M in 2020 and 2019, respectively. The increase was due primarily to increases in headcount and fees related to professional and consulting services.

Net loss in 2020 was $29.9M, compared to $20.5M in 2019.

About NexImmune

NexImmune is a clinical-stage biotechnology company developing a novel approach to immunotherapy designed to employ the body’s own T cells to generate a specific, potent, and durable immune response. The backbone of NexImmune’s approach is a proprietary Artificial Immune Modulation (AIM^™) nanoparticle technology platform. The AIM technology enables NexImmune to construct nanoparticles that function as synthetic dendritic cells capable of directing a specific T cell-mediated immune response. AIM constructed nanoparticles employ natural biology to engage, activate and expand endogenous T cells in ways that combine anti-tumor attributes of antigen-specific precision, potency and long-term persistence with reduced potential for off-target toxicities.

NexImmune’s two lead programs, NEXI-001 and NEXI-002, are in Phase 1/2 clinical trials for the treatment of relapsed AML after allogeneic stem cell transplantation and multiple myeloma refractory to at least 3 prior lines of therapy, respectively. NexImmune is also developing new AIM nanoparticle constructs and modalities for potential clinical evaluation in oncology and in disease areas outside of oncology, including autoimmune disorders and infectious disease.
