NexImmune Reports Third Quarter 2021 Financial Results and Provides Business Updates

• Advancing two lead product candidates in Phase 1/2 clinical trials
• Additional clinical and preclinical data anticipated by year end 2021 and first half 2022
• Announced collaboration with Yale University Department of Immunobiology to explore use of AIM INJ in regard to regulation of Type 1 Diabetes
  
  

GAITHERSBURG, Md., Nov. 12, 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 third quarter of 2021.

"We had another strong quarter as characterized by our continued progress developing the AIM technology platform," said Scott Carmer, Chief Executive Officer. "Our primary focus remains on completing enrollment in our Phase I/II clinical trials for NEXI-001 and NEXI-002. We plan to provide clinical updates for the NEXI-001 trial in AML during the first half of 2022 and will update the NEXI-002 trial in relapsed / refractory multiple myeloma at the upcoming ASH conference. Additionally, we are presenting the antigen peptide targets to be included in our first solid tumor IND application for HPV-associated malignancies at the SITC Annual Meeting. Finally, we're very excited with the progress of our research collaboration with the lab of Professor Kevan Herold at Yale University, which explores the effects of our AIM injectable nanoparticle as a therapeutic for Type 1 Diabetes. Our team looks forward to providing future updates on these and other important projects as we continue to progress the development of our AIM technology across a range of therapy areas and with multiple modalities."

Clinical and Preclinical Updates

NEXI-001

• Robust immune responses across all dose levels with signs of increased clinical activity associated with higher doses
• 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
• Ongoing enrollment in the Phase I/II trial has been affected by higher than anticipated patient replacements between the enrollment and 28-day DLT clearance period due to non-treatment-related events; updated clinical results expected to be announced in the first half of 2022

NEXI-002

• Safety cohort completed and expansion phase continues to enroll and dose
• NEXI-002 continues to be well tolerated with no Grade ≥3 treatment-related adverse events, including infusion reactions, GVHD, CRS or neurotoxicity (ICANS), reported
• Further clinical data from the Phase I/II trial is expected to be announced at the American Society of Hematology (ASH) Annual Meeting in December 2021
  
  

NEXI-003

• Preclinical data supporting the selection of multiple immunogenic antigen peptides commonly expressed on HPV-associated tumors is being presented during the Society for Immunotherapy of Cancer's Annual Meeting (SITC 2021) in November 2021
• Investigational New Drug (IND) submission planned for mid-year 2022

Other R&D

• First collaboration in autoimmune diseases announced with Yale University Professor Kevan Herold to evaluate AIM INJ nanoparticles as a therapeutic in Type 1 diabetes
  
  

Business Updates

• Announced the appointments of Dr. Jack Ragheb as SVP, Translational Medicine, and Matthew Schiller as Head of Business Development
  
  

Select 3Q 2021 Financial Highlights

Cash, cash equivalents and marketable securities for the company as of September 30, 2021 were $93.2M compared to $102.8M for quarter ending June 30, 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 4Q22.

Research and development expenses were $11.3M in the third quarter of 2021, compared to $4.9M 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 $4.2M, compared to $2.8M 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 $14.6M for the quarter, or a basic and diluted GAAP loss per share of $0.65. This compared to a net loss of $8.6M, or a basic and diluted GAAP loss per share of $7.52, 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.
