GAITHERSBURG, Md., May 12, 2022 (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 financial results for the first quarter of 2022.

“This quarter, we have continued to execute on our clinical and corporate strategy, taking the necessary steps to achieve our upcoming catalysts for the remainder of this year,” said Kristi Jones, Chief Executive Officer. “We remain on track to provide a clinical update for the NEXI-001 trial in AML during the second half of 2022, and to provide an update on the expansion cohort in the NEXI-002 trial in relapsed / refractory multiple myeloma. We also plan to file our first solid tumor IND application for HPV-associated malignancies in the near term. In parallel, we are advancing IND-enabling work for our AIM injectable modality and expect to provide updates on preclinical data for oncology and autoimmune indications throughout the second half of the year. With our new target discovery collaborations, we are well-positioned to leverage our modular AIM platform for efficient and rapid new product development. Overall, I am excited with our progress and focus on execution to deliver on upcoming catalysts.”

First Quarter 2022 Clinical and Business Highlights

Clinical and Preclinical Updates

NEXI-001

• Robust immune responses with signs of clinical activity across all dose levels to date
• NEXI-001 continues to be well tolerated across all dose levels administered to date, with no Grade ≥3 treatment-related adverse events, including infusion reactions, GVHD, CRS or neurotoxicity (ICANS), reported
• Due to the favorable emerging clinical profile, plans are underway to expand the addressable population with an additional study arm to include patients with haplo-identical donors
• Enrollment continues, and updated clinical results are expected to be announced in the second half of 2022

NEXI-002

• Expansion phase is ongoing
• In this heavily pre-treated population, evidence of immune response and signals clinical activity have been observed. NEXI-002 continues to be well tolerated with no Grade ≥3 treatment-related adverse events, including infusion reactions, GVHD, CRS or neurotoxicity (ICANS), reported
• Manufacturing achieved higher final cell count yield in recent products by adjusting prior treatment washout period, updating cell collection guidance and other process adjustments
• Further clinical data from the Phase 1/2 trial are expected in the second half of 2022

NEXI-003

• Preclinical data supporting the selection of multiple immunogenic antigen peptides commonly expressed on HPV-associated tumors and a cancer survival antigen was presented during the Society for Immunotherapy of Cancer’s Annual Meeting (SITC 2021) in November 2021
• Finalized antigen selection for NEXI-003 and manufactured nanoparticles for clinical trials
• Investigational New Drug (IND) submission planned for the first half of 2022
  

Injectable AIM nanoparticle programs and other preclinical research

• Advanced in vivo and preclinical work to support the development of AIM injectable nanoparticles as a therapeutic in oncology and autoimmune diseases  
• Advanced work with Yale University Professor Kevan Herold to evaluate AIM INJ nanoparticles for type 1 diabetes. A JDRF grant award will support the collaboration
• Announced a strategic partnership with Zephyr AI in oncology for novel target discovery and validation to support target selection for potential future products candidates
• Announced research collaboration with Rutgers, The State University of New Jersey, for neuroendocrine tumor checkpoint targets, which may have utility in other cancers
• Announced research collaboration with NYU Langone Perlmutter Cancer Center for melanoma neo-antigen-specific CD8+ T cell expansion using the AIM platform technologies
• Announced a preclinical research collaboration with Columbia University Irving Medical Center’s Herbert Irving Comprehensive Cancer Center focused on NexImmune’s AIM ACT in Columbia’s patient-derived organoid models of HPV-associated cancers

Business Updates

• Announced the appointment of Kristi Jones as Chief Executive Officer and Member of the Board of Directors
• Announced the promotion of Mathias Oelke, Ph.D. to Chief Scientific Officer
• Announced the appointment of Dr. Leena Gandhi, Director of Dana-Farber’s Center for Cancer Therapeutic Innovation, to NexImmune’s Board of Directors

• Continued to strengthen the management team with key appointments across the organization
  

Select 1Q 2022 Financial Highlights

Cash, cash equivalents and marketable securities for the Company as of March 31, 2022 were $65.0 million compared to $81.8 million for quarter ending December 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 into the second quarter of 2023.

Research and development expenses were $10.4 million in the first quarter of 2022, compared to $6.0 million 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 $4.6 million, compared to $4.1 million for the same period the prior year. The increase was due primarily to personnel-related expenses and fees related to professional and consulting services.

Net loss, according to generally accepted accounting principles in the U.S. (GAAP), was $15.0 million for the quarter, or a basic and diluted GAAP loss per share of $0.66. This compared to a net loss of $8.5 million, or a basic and diluted GAAP loss per share of $0.71, 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.
