IN8bio Highlights Recent Company Accomplishments and Outlines 2024 Pipeline Goals

• Presented positive data showing continued durable complete remissions (CR) achieved in 100% of evaluable leukemia patients in Phase 1 investigator-sponsored trial of INB-100 at the 65^th American Society of Hematology (ASH) Annual Meeting & Exposition
• Presented new data at Society for Neuro-Oncology (SNO) 28^th Annual Meeting highlighting the potential of INB-200 and INB-400 to treat patients with newly diagnosed glioblastoma multiforme (GBM), with all patients treated with mandated doses of INB-200 exceeding a progression-free survival of seven months
• Appointed internationally recognized immuno-oncology expert Dr. Corinne Epperly, M.D., M.P.H., to IN8bio’s Board of Directors
• Closed private placement in December 2023 with initial gross proceeds of $14.4 million giving a current cash runway into 2025 with potential total of $46.9 million in capital at increasing valuations

NEW YORK, Jan. 04, 2024 (GLOBE NEWSWIRE) — IN8bio, Inc. (NASDAQ: INAB), a leading clinical-stage biopharmaceutical company developing innovative gamma-delta T cell therapies, today highlighted recent business updates and provided pipeline goals for 2024.

“2023 was a year marked by strong execution for IN8bio. We delivered on several clinical milestones, reporting positive data updates across our pipeline of innovative gamma-delta T cell therapies at many prestigious medical meetings, and secured the financing to extend our runway into 2025,” said William Ho, CEO and co-founder of IN8bio. “We continue to be excited by the data from the Phase 1 trial of INB-100, which showed that all evaluable patients remained in durable complete remission, with six patients remaining relapse free beyond one year. Importantly, we are excited that we are seeing in vivo expansion and persistence of allogeneic gamma-delta T cells, now out to 365 days. This persistence clearly differentiates our results from the data presented on other allogeneic cellular therapies to date and we believe this data underscores the far-reaching potential of gamma-delta T cells to help provide durable relapse-free periods in patients with hematologic malignancies undergoing haploidentical stem cell transplantation. We believe we are well positioned to execute on our clinical programs and are poised for many exciting updates in 2024.”

Recent Company Updates

• Announced positive clinical update demonstrating continued durable complete remissions in 100% of evaluable patients (n=10) in the Phase 1 trial of INB-100 in leukemia patients undergoing haploidentical stem cell transplantation. The data was presented at the ASH Annual Meeting in December.
• Presented data demonstrating INB-200’s extended progression-free survival in glioblastoma multiforme (GBM) patients and potential for INB-400 to treat GBM at the SNO Annual Meeting.
• Initiated enrollment for the Phase 2 trial of INB-400 in GBM (NCT05664243).
• Announced a private placement totaling up to $46.9 million in gross proceeds. The initial closing of $14.4 million is expected to support operational execution and extended the Company’s cash runway into 2025 with the potential for up to $32.5 million in additional capital at increasing valuations.
• Appointed internationally recognized immuno-oncology expert Dr. Corinne Epperly, M.D., M.P.H., to IN8bio’s Board of Directors.

Anticipated 2024 Pipeline Goals

• INB-100: Enroll an additional 10 patients in an expansion cohort at the recommended Phase 2 dose (RP2D) and report Phase 1 long-term follow-up results at multiple medical meetings throughout 2024; potentially submit IND for Phase 3 randomized control trial in 2024.
• INB-200: Report Phase 1 long-term follow up results at multiple medical meetings in 2024.
• INB-300: Present additional preclinical data demonstrating proof-of-concept for the nsCAR platform targeting CD33 and CD123 at American Association for Cancer Research (AACR) 2024.
• INB-400: Dose first patient and treat up to 15 patients at multiple sites across the United States in the Phase 2 trial in newly diagnosed GBM; potentially submit IND for allogeneic Phase 1b in relapsed GBM in 2024.
