IN8bio Reports Second Quarter 2022 Financial Results and Provides Corporate Update

• Unveiled a new preclinical program focused on developing iPSC derived gamma-delta T cells and presented early findings at the ASGCT Annual Meeting.
• Presented data from Phase 1 clinical trial of INB-200 in patients with newly diagnosed GBM showing five of six fully dosed patients exceeded both median and expected progression free survival (PFS), with a sixth patient early in follow up; two patients have exceeded overall survival (OS) benchmarks established by Stupp et al, 2005 to-date.
• Continued to demonstrate durable morphologic complete responses from INB-100 Phase 1 clinical trial in leukemia patients with two of three patients relapse free at two years to date and all three relapse free past one year.
• Appointed seasoned executives to the roles of Senior Vice President, Business Development, Vice President, Regulatory Affairs, and Vice President, Clinical Operations.

NEW YORK, Aug. 12, 2022 (GLOBE NEWSWIRE) -- IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company focused on discovering and developing innovative gamma-delta T cell therapies that utilize its DeltEx platform, today announced financial results and operational highlights for the quarter ended June 30, 2022. In addition, the Company provided an overview of recent corporate developments.

“Our team continues to execute and advance our gamma-delta programs on multiple fronts. Our Phase 1 clinical trials for both DeltEx product candidates, INB-200 in GBM and INB-100 in leukemia patients undergoing stem cell transplantation, continue to progress with encouraging durability data. We introduced our iPSC derived gamma-delta T cell platform at the ASGCT annual meeting, and we have been receiving positive feedback on this new program,” said William Ho, CEO and co-founder of IN8bio. “During the quarter and into July, we continued to expand our management team; we have attracted talented individuals who have built their careers and established their reputations in well-recognized companies like Genentech, Novartis, Janssen, Bristol Myers Squibb and Covance. We believe they will be instrumental in shaping IN8bio’s future. The IN8bio team continues to be disciplined, and we are working to dedicate our resources to accelerating IN8bio’s growth and momentum.”

Business Highlights & Clinical Updates

• In May 2022, IN8bio unveiled a new preclinical program focused on developing induced pluripotent stem cell (iPSC) derived gamma-delta T cells and presented its early findings at the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting. Uniquely, IN8bio has been able to demonstrate the ability to derive both Vd1+ and Vd2+ iPSC gamma-delta T cell clones. These iPSC-derived gamma-delta T cells demonstrated robust cytotoxicity and can be genetically modified with an internally developed chimeric antigen receptor (CAR-T) construct at a high transduction yield. Scalable iPSC-based cellular manufacturing is designed to create for a uniform and renewable therapeutic product available “off-the-shelf” for patients.
• In June 2022, IN8bio provided an update on the INB-200 Phase 1 clinical trial in newly diagnosed glioblastoma multiforme (GBM) patients at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting. Five of six fully dosed patients exceeded both median and expected progression-free survival (PFS), and two patients exceeded the expected overall survival (OS) benchmarks as of June 3, 2022. All patients demonstrated a manageable toxicity profile with no evidence of cytokine release syndrome (CRS), tumor lysis syndrome (TLS) or immune effector cell-associated neurotoxicity syndrome (ICANS).
• In June 2022, IN8bio held a successful pre-investigational new drug application (pre-IND) meeting with the Food and Drug Administration. The meeting provided guidance and confirmed IND filing requirements for the INB-400 program. IN8bio expects to file the IND by year-end.
• In July 2022, IN8bio announced a patent covering the composition of matter for IN8bio’s Drug Resistant Immunotherapy (DRI) platform. The patent broadens the Company’s intellectual property coverage of genetically engineered innate immune cells beyond gamma-delta T cells to include NK cells.
• In July 2022, IN8bio provided an update from the ongoing Phase 1 clinical trial of INB-100 in leukemia patients undergoing haploidentical stem cell transplantation. All three high-risk AML patients from the first cohort continue to demonstrate durable morphologic complete responses (CR) and remain progression-free and alive for more than one year. Two of the three patients remain in morphologic CR for more than two years. The safety profile continues to be manageable with no dose-limiting toxicities.
  

Recent Team Growth

• In April 2022, IN8bio announced the expansion of its clinical and regulatory teams with the appointments of Urvashi Patel, Ph.D., Vice President, Regulatory Affairs, and Stacey Bilinski, Vice President, Clinical Operations. They bring more than a combined 45 years of clinical and regulatory experience to the IN8bio team.
  
• In July 2022, IN8bio appointed Kenneth R. LaMontagne, Ph.D., as Senior Vice President, Business Development to lead the Company’s business development activities. Dr. LaMontagne is an industry leader with more than 20 years of experience, including licensing, collaborations, search and evaluation, M&A and corporate strategy including in the fields of cell therapy and oncology. He gained his experience in both large pharma and small biopharmaceutical companies.

Second Quarter 2022 Financial Results
Research and development (R&D) expenses were $3.5 million for the three months ended June 30, 2022, compared to $2.1 million for the comparable prior year period. The increase in R&D expenses were primarily due to (i) increased third-party clinical trial and IND-related activities, (ii) contract manufacturing costs for the ongoing INB-200 clinical trial and (iii) increased personnel-related costs, including salaries, benefits and stock-based compensation due to increased headcount.

General and administrative expenses were $3.7 million for the three months ended June 30, 2022, compared to $1.0 million for the comparable prior year period. The increase was primarily due to increased headcount, insurance, legal expenses, and expenses associated with operating as a public company.

The Company reported a net loss attributable to common stockholders of $7.2 million, or $0.38 per basic and diluted common share, for the three months ended June 30, 2022, compared to a net loss attributable to common stockholders of $3.8 million, or $1.00 per basic and diluted common share, for the comparable prior year period.

As of June 30, 2022, the Company had cash of $25.7 million, compared to $37.0 million as of December 31, 2021. The decrease in cash was primarily due to cash used by the Company in R&D and continued operations to advance its programs along with ongoing construction of a state-of-the-art ~10,000 sq. ft. R&D facility in Birmingham, AL.
