IN8bio's 2024 Financials: A Mixed Bag of Clinical Triumphs and Financial Challenges

IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company, has reported its financial results and business highlights for the fourth quarter and full-year ended December 31, 2024. The company's financial performance in 2024 presents a mixed picture, with significant implications for its ability to sustain ongoing clinical programs and future development milestones. The company reported a net loss of $30.7 million for the full year 2024, which is a 2.3% increase from the previous year. This net loss translates to a loss of $0.57 per share, indicating substantial financial strain. The company ended 2024 with a cash position of $11.1 million, which is a significant decrease from the $21.3 million reported at the end of 2023. This reduction in cash position raises concerns about the company's liquidity and its ability to fund ongoing operations and development milestones.

However, IN8bio has taken steps to mitigate these financial challenges. The company raised approximately $16.6 million in gross proceeds through various equity offerings, including through its at-the-market ("ATM") offering program and private placements, during 2024 through February 2025. This additional funding has extended the company's cash runway into March 2026, providing some breathing room for continued operations. Furthermore, IN8bio implemented cost-saving measures, such as pausing enrollment in the Phase 2 INB-400 glioblastoma program and reducing its workforce, which resulted in $1.1 million in severance charges. These measures are aimed at prioritizing pipeline development and extending the cash runway.

Despite these challenges, IN8bio's clinical data shows noteworthy therapeutic potential across multiple programs. The INB-100 program's 100% long-term durable response rates in high-risk AML patients is particularly significant, as this population typically faces poor outcomes. The favorable safety profile – specifically the absence of cytokine release syndrome (CRS) or neurotoxicity (ICANs) – addresses major limitations of existing cell therapies. The glioblastoma program (INB-200) data presented at SNO indicates efficacy above expected progression-free survival benchmarks, with one IDH-mutant grade 4 glioma patient remaining progression-free for 40.5 months post-treatment – exceptional durability for this aggressive brain cancer.

The new INB-600 platform represents an important technological advancement in T cell engager (TCE) design. By targeting gamma-delta T cells rather than conventional CD3+ T cells, this approach may overcome limitations of existing TCEs like blinatumomab, potentially improving both durability and safety profiles. The CD19-targeting strategy aligns with validated targets in both oncology and autoimmune diseases.

The pausing of the Phase 2 INB-400 glioblastoma program has several strategic implications for IN8bio's resource allocation and future pipeline development. Firstly, it allows the company to focus its resources on high-impact programs, such as the INB-100 program for high-risk leukemias including AML. This strategic move enables IN8bio to prioritize programs with the strongest clinical data and potential for regulatory success.

Secondly, the pausing of INB-400 allows IN8bio to implement cost-saving measures, which extend the company's cash runway. This financial discipline is crucial for a small-cap biotech company with a market capitalization of $17.4M, as it ensures that IN8bio can continue to operate and advance its pipeline without running out of cash.

Thirdly, the pausing of INB-400 signals IN8bio's intent to seek external funding or partnerships for its solid tumor applications. This strategy could potentially bring in additional capital and expertise to support the development of INB-400 and other solid tumor programs in the future.

Lastly, the pausing of INB-400 allows IN8bio to accelerate patient enrollment in the expansion cohort of the INB-100 clinical trial, which is a top priority for the company. This strategic refocusing demonstrates appropriate pipeline prioritization for a company with limited resources, as it allows IN8bio to drive significant value creation with its most promising program.

The introduction of the INB-600 platform and the novel gamma-delta T Cell engager (TCE) targeting CD19 positions IN8bio competitively in the oncology and autoimmune disease markets by offering a potentially superior therapeutic approach. The INB-600 platform features INB-619, a proprietary next-generation gamma-delta TCE that targets CD19, a validated target in both oncology and autoimmune diseases. This platform aims to improve both the durability of response and safety compared to existing CD3 targeting TCE therapies.

Preclinical studies have demonstrated potent B-cell depletion and sustained gamma-delta T cell expansion with INB-619, which offers commercial and scientific advantages. By targeting gamma-delta T cells rather than conventional CD3+ T cells, INB-619 may overcome limitations of existing TCEs like blinatumomab, potentially improving both durability and safety profiles. This technological advancement positions IN8bio as a leader in the T cell engager landscape, with the potential to reshape the market by offering more effective and safer treatments for patients with oncology and autoimmune diseases.

The strategic focus on aligning resources and driving high-impact programs forward, as evidenced by the pausing of the Phase 2 INB-400 glioblastoma program and the implementation of cost-saving measures, further strengthens IN8bio's competitive position. The company's ability to raise approximately $16.6 million in gross proceeds through various equity offerings, including through their at-the-market (“ATM”) offering program and private placements, extends their cash runway into March 2026, providing the financial stability needed to advance their innovative pipeline.



In summary, while IN8bio's financial performance in 2024, particularly the net loss and reduced cash position, poses challenges to sustaining ongoing clinical programs and future development milestones, the company's strategic initiatives, including cost-saving measures and additional fundraising, provide a pathway to continue its operations. The promising clinical data and technological advancements in its pipeline further support the company's potential for long-term success.
