NexImmune Reports First Quarter 2023 Financial Results and Provides Business Updates

• Company has initiated pre-IND discussions with the FDA for its first AIM INJ indication
  
  
• NEXI-001 Phase I data to be presented at ASCO 2023 in June

GAITHERSBURG, Md., May 15, 2023 (GLOBE NEWSWIRE) -- NexImmune, Inc. (NASDAQ:NEXI), a biotechnology company developing a novel approach to immunotherapy designed to orchestrate a targeted immune response by directing the function of antigen-specific T cells in oncology, autoimmune and infectious diseases, today reported financial results for the first quarter 2023.   

"This is an exciting time for NexImmune, as we remain focused on progressing the development of novel approaches in the field of immunotherapy," said Kristi Jones, NexImmune's CEO.  "Interest in antigen specific approaches for oncology, autoimmune disorders and infectious diseases has never been higher. We believe our AIM INJ direct injectable nanoparticle platform offers a unique and powerful solution to direct a multi-antigen specific T cell response in a scalable "off-the-shelf" approach across these disease areas. We continue to move our INJ "off-the-shelf" lead program forward in oncology and are encouraged by our conversations with the FDA."

"I am also pleased that our NEXI-001 Phase 1 clinical data in cell therapy has been accepted for presentation at ASCO and I look forward to reviewing this data, as well as the preclinical data across oncology, autoimmune and infectious disease areas for our "off-the-shelf" injectable this year."

"We remain confident in the potential therapeutic benefit of our AIM platform-based product candidates and their ability to significantly impact the emerging, rapidly moving field of antigen specific immuno-oncology therapies, novel IO/IO combinations, autoimmune disorders and virally-driven diseases."

Select First Quarter 2023 Financial Highlights

Cash and cash equivalents for the Company as of March 31, 2023 were $22.3 million compared to $34.6 million at December 31, 2022. Based upon current operating plans, NexImmune expects that its existing cash and cash equivalents will enable the Company to fund its operating and capital expenditure requirements into the fourth quarter of 2023.

Research and development expenses were $6.1 million in the first quarter of 2023, compared to $10.4 million for the same period in the prior year. The decrease of $4.3 million was due primarily to the completion of preclinical manufacturing work and the pausing of the clinical trials.

General and administrative expenses were $3.7 million, compared to $4.6 million for the same period in the prior year. The decrease was primarily due to decreases in personnel-related expenses and in legal and other administrative expenses.

Net loss, according to generally accepted accounting principles in the U.S. GAAP, was $9.6 million for the quarter, or a basic and diluted GAAP net loss per share of $0.37. This compares to a net loss of $15.0 million, or a basic and diluted GAAP net loss per share of $0.66, for the same period in 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 is focused on developing injectable AIM nanoparticle constructs and modalities for potential clinical evaluation in oncology, autoimmune disorders and infectious diseases.
