• INB-400 on track to initiate enrollment in glioblastoma multiforme (GBM) in the second half of 2023. The Phase 2 trial (NCT05664243) will initially enroll newly diagnosed GBM patients in the autologous setting. The primary endpoint of the study is overall survival (OS); secondary endpoints include tolerability, progression-free survival (PFS), overall response rate (ORR) and time to progression (TTP)
  
• Promising preclinical data in ovarian cancer announced at the American Society of Gene & Cell Therapy (ASGCT) Annual Meeting underscores the synergistic potential of DeltEx gamma-delta T cells and chemotherapy to target solid tumors beyond brain cancer
  
• Additional clinical and pipeline updates expected at a research and development (R&D) day on October 12, 2023 in New York City and at fall medical meetings with abstracts submitted for Society for Immunotherapy of Cancer (SITC), Society for Neuro-Oncology (SNO), and the American Society of Hematology (ASH) Annual Meetings in the fourth quarter of 2023
  

NEW YORK, Aug. 10, 2023 (GLOBE NEWSWIRE) -- IN8bio, Inc. (Nasdaq: INAB), a leading clinical-stage biopharmaceutical company developing innovative gamma-delta T cell therapies, today announced financial results and operational highlights for the second quarter ended June 30, 2023. In addition, the Company provided an overview of recent corporate developments through August 2023.

“We made significant clinical advancements in our gamma-delta T cell programs in the second quarter of 2023, sharing encouraging positive data from our INB-100 and INB-200 programs at major medical meetings as well as increasing enrollment across our clinical pipeline,” said William Ho, CEO and co-founder of IN8bio. “We were honored to be selected as one of only four oral presentations and the only Phase 1 program for central nervous system tumors at the ASCO 2023 Annual Meeting. The positive clinical data from both of our Phase 1 trials continues to demonstrate the potential of gamma-delta T cell therapy in preventing relapse and ultimately prolonging survival in patients with these devastating diseases. Our clinical programs investigate the safety, durability and potential utility of gamma-delta T cells as a much-needed treatment option for cancer patients. We look forward to providing additional updates at medical meetings this fall.”

Business Highlights and Recent Developments

• Presented positive INB-200 Phase 1 data update in GBM showing 100% of treated patients (n=8) to date have exceeded median progression-free survival at the ASCO 2023 Annual Meeting. Results support the potential of DeltEx drug resistant immunotherapy (DRI) to improve progression-free survival and overall survival in patients with newly diagnosed GBM, demonstrating that multiple doses in later cohorts did not lead to any changes in toxicity profile. The Company is on track to complete INB-200 Phase 1 study enrollment in 2023 with updated data expected to be presented later this year.
  
• Presented new promising preclinical data underscoring the potential of DeltEx gamma-delta T cells to target and kill ovarian cancer cells at the ASGCT 26th Annual Meeting. The results showcased the powerful synergistic potential of combining gamma-delta T cells and chemotherapy to enhance their ability to recognize and eradicate cancer cells across a broad range of challenging cancer indications beyond the brain and has the potential to be developed as a novel therapy for ovarian cancer.
  
• Announced upcoming R&D Day in October. The Company will be hosting an R&D Day on Thursday, October 12, 2023 in New York City, with details to follow.
• Announced opening of advanced R&D facility in Birmingham. The Company recently announced that it has opened a new R&D facility in Birmingham, AL. Complementing the Company’s current GMP manufacturing spaces, this facility will play a vital role in enhancing the Company's preclinical R&D and process development capabilities. These facilities will be instrumental in advancing our groundbreaking pipeline of gamma-delta T cell therapies, setting the stage for future clinical and pipeline developments.
  

Second Quarter 2023 Financial Highlights

• Research and Development expenses: R&D expenses were $4.1 million for the three months ended June 30, 2023, compared to $3.5 million for the comparable prior year period. The increase in R&D expenses was primarily due to (i) contract research organization expenses related to the initiation of INB-400, (ii) completion of additional lentiviral vector manufacturing to support the INB-400 program and (iii) increased personnel-related costs, including salaries, benefits, and stock-based compensation due to increased headcount.
• General and administrative expenses: General and administrative expenses were $3.6 million for the three months ended June 30, 2023, compared to $3.7 million for the comparable prior year period. The decrease was primarily due to cost savings related to D&O insurance premiums and reductions in professional services.
• Net loss: The Company reported a net loss of $7.7 million, or $0.27 per basic and diluted common share, for the three months ended June 30, 2023, compared to a net loss of $7.2 million, or $0.38 per basic and diluted common share, for the comparable prior year period.
• Cash: As of June 30, 2023, the Company had cash of $17.0 million, compared to $10.9 million as of March 31, 2023.
