• Announcing first solid tumor indication in HPV associated-malignancies – NEXI-003
• Advancing two lead product candidates in Phase 1/2 clinical trials
• Additional clinical and preclinical data anticipated in the second half of 2021
  

GAITHERSBURG, Md., Aug. 09, 2021 (GLOBE NEWSWIRE) -- 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 the second quarter of 2021.

“The first half of the year was a very productive period for the company. We are focused on completing enrollment in our Phase I/II clinical trials for NEXI-001 and NEXI-002 and expect to present additional clinical data for each during scientific conferences toward the end of this year,” said Scott Carmer, Chief Executive Officer. “We are also excited to announce our first indication in solid tumors and expect to submit our IND for HPV-associated malignancies in the second quarter of 2022. Additionally, we’ve initiated IND-enabling pre-clinical experiments that will be the basis for multiple IND submissions in support of our injectable nanoparticle (AIM INJ). This progress highlights the promise of our AIM platform across disease areas and delivery modalities, and we look forward to providing further updates on these important programs later this year.”

Select 2Q 2021 Financial Highlights

Cash, cash equivalents and marketable securities for the company as of June 30, 2021 were $102.8M compared to $118.1M for quarter ending March 31, 2021. Based upon current operating plans, NexImmune expects that its existing cash, cash equivalents and marketable securities will enable the company to fund its operating and capital expenditure requirements through the third quarter of 2022.

Research and development expenses were $8.1M in the second quarter of 2021, compared to $4.2M for the same period in the prior year. The increase in R&D expenses was mainly attributable to costs for the two clinical trials, as well as personnel-related expenses driven by increased headcount.

General and administrative expenses were $4.0M, compared to $2.6M for the same period the prior year. The increase was due primarily to increases in headcount and fees related to professional and consulting services.

Net loss, according to generally accepted accounting principles in the U.S. (GAAP), was $12.2M for the quarter, or a basic and diluted GAAP loss per share of $0.54. This compared to a net loss of $6.9M, or a basic and diluted GAAP loss per share of $6.17, for the same period the prior year.

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 3 or more 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.
