IN8bio Reports First Quarter 2024 Financial Results and Recent Corporate Highlights

- Presented new preclinical data demonstrating proof-of-concept for non-signaling Chimeric Antigen Receptor (nsCAR) platform to effectively target cancer cells while preserving healthy tissue

- Demonstrated potential of nsCAR platform to treat previously “undruggable” solid and liquid tumor targets

- Announced peer-reviewed publication in ‘Frontiers in Immunology’ on IN8bio’s DeltEx Drug Resistant Immunotherapy (DRI) approach to newly diagnosed glioblastoma multiforme (GBM)

- Dosed first patient in autologous arm of INB-400 Phase 2 clinical trial for patients with newly diagnosed GBM

NEW YORK, May 09, 2024 (GLOBE NEWSWIRE) -- IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company developing innovative gamma-delta T cell therapies, today reported financial results for the first quarter ended March 31, 2024 and recent corporate highlights.

“We continued to make significant progress advancing our gamma-delta T cell programs in the first quarter of 2024,” said William Ho, CEO and co-founder of IN8bio. “We presented new preclinical data on our nsCAR platform at the American Association for Cancer Research (AACR) 2024 Annual Meeting demonstrating its potential to target and kill various acute myeloid leukemia (AML) cells by targeting CD33 and/or CD123, while preserving healthy bone marrow cells. These findings reinforce our technology’s ability to precisely target “undruggable” cancer targets that have historically been challenging due to on-target, off-tumor toxicity. We will provide an update from our Phase 1 study of INB-100 at the 2024 European Hematology Association (EHA) Annual Meeting in June, including patient status and survival rate data. We anticipate enrolling ten additional patients in an expansion cohort at the recommended Phase 2 dose, and could potentially submit an investigational new drug (IND) application for a Phase 2 randomized control trial this year. In addition, at the American Society of Clinical Oncology (ASCO) Annual Meeting, we will provide an update on our Phase 1 INB-200 study in GBM which generated an initial efficacy signal supporting the INB-400 trial.”

Corporate Highlights and Recent Developments

  • Presented data at AACR 2024, supporting the potential of proprietary constructs targeting CD33 and/or CD123 for in vitro evaluation against various types of leukemia, including AML and chronic myeloid leukemia (CML).
    • Demonstrated significant differences between cells expressing traditional signaling chimeric antigen receptors (CARs) and those expressing nsCAR constructs, which include a reduction in activation-induced cell death with nsCAR constructs.
  • Peer-reviewed publication of “Adoptive Cell Therapy for High Grade Gliomas using Simultaneous Temozolomide and Intracranial MGMT-Modified γδ T cells Following Standard Post-Resection Chemotherapy and Radiotherapy: Current Strategy and Future Directions” in Frontiers in Immunology detailing IN8bio’s DeltEx Drug Resistant Immunotherapy (DRI) as a rational therapeutic approach for newly diagnosed GBM.
  • Announced first patient dosed in the Phase 2 autologous arm of INB-400 in patients with newly diagnosed GBM.

Upcoming Anticipated Pipeline Milestones and Events

  • American Society of Gene & Cell Therapy (ASGCT) 2024 Annual Meeting (May 10, 2024): Upcoming oral presentation: “Healthy Donor vs Patient Manufactured Autologous DeltEx DRI Product; Immunophenotyping Gene Expression,” will unveil new data highlighting the characterization of our clinical manufactured DeltEx DRI product. The presentation will explore the impact of manufacturing on the final cell product from healthy donors and those manufactured from cancer patients, showcasing IN8bio’s robust capabilities and know-how in complex cell therapy process development and manufacturing.
  • INB-100: Report updated interim results from the ongoing Phase 1 investigator-sponsored trial at the 2024 EHA Annual Meeting, held June 13-16 in Madrid, Spain. In addition, we will potentially submit an IND application for a Phase 2 registrational trial in 2024 in the AML and myelodysplastic syndrome (MDS) patient setting.
  • INB-200: Report interim Phase 1 long-term follow up results in GBM at multiple medical meetings in 2024 including at the 2024 ASCO Annual Meeting.
  • INB-400: Initiated patient dosing in the Phase 2 autologous arm of INB-400 in newly diagnosed GBM. IN8bio expects to treat up to a total of 40 patients in arm A at multiple sites across the United States.

First Quarter 2024 Financial Highlights

  • Research and Development (R&D) expenses: R&D expenses were $4.9 million, compared to $4.4 million for the comparable prior year period. The increase was primarily due to (i) increased personnel-related costs, including salaries and stock-based compensation due to increased headcount and (ii) direct clinical costs for INB-100, INB-200 and INB-400.
  • General and administrative expenses: General and administrative expenses were $3.7 million, compared to $3.5 million for the comparable prior year period. The increase was primarily due to increased personnel-related costs, including stock-based compensation and rent, offset by cost savings related to directors’ and officers’ insurance premiums and a reduction in professional services.
  • Net loss: Net loss was $8.6 million, or $0.20 per basic and diluted common share, compared to a net loss of $7.5 million, or $0.30 per basic and diluted common share, for the comparable prior year period.
  • Cash position: As of March 31, 2024, the Company had cash of $13.0 million, compared to $21.3 million, as of December 31, 2023.
