IN8bio Reports Second Quarter 2024 Financial Results and Recent Corporate Highlights

IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company developing innovative gamma-delta T cell therapies for solid and hematologic cancers, today reported financial results for the second quarter ended June 30, 2024 and recent corporate highlights.

“Gamma-delta T cell therapies have the potential to revolutionize cancer treatment,” said William Ho, CEO and co-founder of IN8bio. “In the second quarter of 2024, our team presented industry-leading data demonstrating that our gamma-delta T cell therapeutic approach in INB-100 and INB-200 can drive durable complete remissions compared to the current standard-of-care in certain aggressive cancers like GBM and AML, where patients have typically faced poor outcomes. This novel approach that leverages gamma-delta T cells seeks to target residual tumors, including chemo-resistant and cancerous stem cells that often result in relapse. We look forward to providing additional updates on our gamma-delta T cell programs as we generate longer patient follow-up and advance our pipeline.”

Corporate Highlights and Recent Developments

Presented data at EHA 2024, showing 100% of treated patients with leukemia (n=10/10) in the Phase 1 trial of INB-100 remained progression-free for at least one year, including high-risk and relapsed AML and one with acute lymphocytic leukemia (ALL) who had previously failed multiple lines of therapy, including CAR-T.
- Data continue to show long-term in vivo expansion and persistence of haplo-matched allogeneic gamma-delta T cells 365 days following a single administration post-transplant, demonstrating the first-ever durable persistence and in vivo expansion of an allogeneic cellular therapy.
- As of May 31, 2024, two of the patients treated with INB-100 remain alive and relapse free for over three and a half years, and a third patient is nearing three years.
Poster presentation at ASCO 2024 demonstrated that 92% of evaluable patients treated with INB-200 exceeded a median PFS of seven months with concomitant temozolomide (TMZ), as of a data cutoff date of May 30, 2024.
- The survival data along with radiographic improvements are indicative of positive treatment effects, which highlight the potential of IN8bio’s genetically modified, chemotherapy-resistant gamma-delta T cells as a potential first-in-class therapy for patients with newly diagnosed GBM to extend PFS.
- The safety profile of gamma-delta T cells continues to be strong across all three dose cohorts with no cell therapy-related toxicities such as immune effector cell-associated neurotoxicity syndrome or cytokine release syndrome reported in any patients across both Phase 1 trials to date (up to the maximum dose of six infusions of therapy).
Multiple presentations at the International Society for Cell & Gene Therapy (ISCT) 2024 demonstrated how IN8bio’s manufacturing process influences product characteristics and the ability to generate a robust, activated and reproducible final product.
- DeltEx gamma-delta T cell manufacturing platform has enabled the development of multiple investigational candidates which are now moving into multi-center Phase 2 clinical trials and are designed to target and potentially eradicate cancer cells to help improve patient outcomes.
The cellular characteristics of products from the company’s proprietary clinical-scale gamma-delta T cell manufacturing platform were shown across different donor populations at the ASGCT 2024 Annual Meeting.
- Data demonstrated that the manufacturing process results in investigational products with upregulated markers of potency, effector functions and trafficking capabilities, which IN8bio believes represents a significant advancement in the characterization of gamma-delta T cell-based therapies.

Second Quarter 2024 Financial Highlights

Research and Development (R&D) expenses: R&D expenses were $5.2 million, compared to $4.1 million for the comparable prior year period. The increase was primarily due to a $0.5 million increase in personnel-related costs, including salaries and non-cash stock-based compensation due to increased headcount. Direct clinical costs increased by $0.5 million due to increased enrollment costs for our clinical programs, partially offset by a decrease of $0.1 million in facilities costs.
General and administrative expenses: General and administrative expenses remained flat at $3.5 million, compared to $3.6 million for the comparable prior year period.
Net loss: Net loss was $8.6 million, or $0.19 per basic and diluted common share, compared to a net loss of $7.7 million, or $0.27 per basic and diluted common share, for the comparable prior year period.
Cash position: As of June 30, 2024, the Company had cash of $10.2 million, compared to $21.3 million, as of December 31, 2023.
