INAB IN8bio Inc

IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company focused on the discovery and development of innovative gamma-delta T cell therapies utilizing its DeltEx platform, today announced financial results and operational highlights for the third quarter ended September 30, 2021. In addition, the Company provided an overview of recent corporate developments.

“Our IPO has provided the capital to enable us to advance our clinical programs for INB-100 in leukemia and INB-200 in newly diagnosed glioblastoma (GBM) and other solid tumors as well as progress our preclinical-stage assets,” said William Ho, Chief Executive Officer and co-founder of IN8bio. “Both of our clinical programs continue to progress and we took the opportunity during the required safety observation period for the allogeneic INB-100 trial to improve our manufacturing processes and overall gamma-delta T cell yield. We look forward to the continued advancement of our clinical and preclinical programs and to providing updates on them in the future.”

Third Quarter Business Highlights & Corporate Updates

• In July 2021, IN8bio appointed Emily Fairbairn and Luba Greenwood as two independent members of the Company’s Board of Directors. Ms. Fairbairn is currently a principal of Transcend Partners and was co-founder and CEO of Ascend Capital. Ms. Greenwood serves as Managing Partner of Binney Street Capital LLC, a venture capital fund established by the Dana Farber Cancer Institute, and as CEO of LUCA Biologics.
• In August 2021, IN8bio closed its initial public offering, in which it issued and sold 4,000,000 shares of common stock at a public offering price of $10.00 per share. The net proceeds to the Company were approximately $32.3 million, after deducting underwriting discounts, commissions and offering expenses.
• In August 2021, IN8bio completed dosing of the first cohort of INB-100, a Phase 1 clinical trial of donor-derived allogeneic gamma-delta T cells in leukemia patients undergoing haploidentical hematopoietic stem cell transplant (HSCT). No severe adverse infusion reactions, cytokine release syndrome, neurotoxicity (or ICANS) or dose-limiting toxicities were observed. Episodes of mild-to-moderate acute skin graft-versus-host-disease (GvHD) responsive to standard therapy have been observed. Additional patients will be enrolled at the first dose-level to further assess these events and any potential relationship to the ongoing positive clinical responses observed in the INB-100 treated patients. Skin biopsies were consistent with the expected pathology in post-HSCT GvHD and the vast majority of immune cell infiltration were alpha-beta T cells. All three patients treated with INB-100 continue in remission with the first two patients beyond 18- and 16-months post-transplant, respectively. The Company continues to expect to report initial results from the first cohort in this Phase 1 trial in 2022, with topline results for all cohorts in 2023.
• In September 2021, IN8bio announced the peer-reviewed publication of preclinical results that it believes provides foundational support for the use of its DeltEx Drug Resistant Immunotherapy (DRI) in newly diagnosed GBM. This work, published in Scientific Reports, a Nature Portfolio journal, focused on the use of gamma-delta T cells genetically engineered to be chemotherapy resistant through the addition of an O6-Methylguanine-DNA Methyltransferase (MGMT). Concurrent dosing of DRI cells with temozolomide (TMZ) resulted in a significant improvement in survival outcomes in mice over either monotherapy alone in both classical and mesenchymal primary high-grade gliomas.
• In October and November 2021, the Company presented updates on its programs at the 2021 Advanced Therapies Congress and at the 13th Annual Protein and Antibody Engineering Summit (PEGS) Europe.

Upcoming Scientific Presentations

• 36th Annual Meeting of the Society for Immunotherapy of Cancer (SITC), November 10 - 14, 2021.
• 26th Annual Meeting of the Society of Neuro-Oncology (SNO), November 18 - 21, 2021.

Third Quarter 2021 Financial Highlights

• Cash position: As of September 30, 2021, the Company had cash of $40.7 million, compared to $18.0 million as of December 31, 2020. The increase in cash was primarily due to the IPO proceeds, net of cash used by the Company in operations to advance its programs and research and development.
• Research & Development (R&D) expense: R&D expense was $1.4 million for the three months ended September 30, 2021, compared to $1.1 million for the comparable prior year period. The increase in R&D expense was primarily due to increased third-party clinical trial related activities and contract manufacturing costs for the ongoing clinical trials and increased personnel-related costs, including salaries, benefits and stock-based compensation.
• General and administrative expense: General and administrative expense was $2.0 million for the three months ended September 30, 2021, compared to $0.6 million for the comparable prior year period. The increase was primarily due to increased personnel costs, including salaries, benefits and stock-based compensation and increased legal expenses in anticipation of operating as a public company.
• Net loss: The Company reported a net loss of $3.4 million, or $0.25 per basic and diluted common share, for the three months ended September 30, 2021, compared to a net loss of $1.7 million and a net loss attributable to common stockholders of $2.2 million, or $0.60 per basic and diluted common share, for the comparable prior year period.
