Current report
Nature Oncogene highlights two landmark cases from this program, the most recent of which was published in July 2025:
Current report
A patient with refractory metastatic testicular cancer who achieved a durable complete remission following a single infusion of agenT-797 in combination with checkpoint blockade after failing multiple lines of therapy, including platinum chemotherapy and immune checkpoint inhibitors. The patient remains disease-free more than two years post-treatment.
Current report
A patient with advanced gastric cancer who achieved a durable partial response with agenT-797 plus checkpoint blockade, with meaningful tumor reduction and sustained disease control despite prior progression on standard therapies.

Current report
Other expense increased to approximately $186,000 for the three months ended June 30, 2025 from income of approximately $331,000 for the three months ended June 30, 2024, primarily due to foreign currency exchange losses in the three months ended June 30, 2025, compared to the $185,000 gain recognized on the deconsolidation of a foreign subsidiary and the recognition of a refundable R&D tax credit in the UK in the three months ended June 30, 2024.

G&A expense consists primarily of personnel costs, facility expenses, and professional fees. G&A expense increased 33% to $3.1 million for the six months ended June 30, 2025 from $2.3 million for the six months ended June 30, 2024. This increase is primarily due to an increase in professional fees and the incremental share-based compensation expense resulting from the option award modification approved by shareholders in June 2025.

Previous wording
In solid cancers, we completed a Phase 1 clinical trial of agenT-797 in solid tumor cancers, both as a monotherapy and in combination with anti-PD-1 checkpoint inhibitors pembrolizumab and nivolumab. The trial demonstrated durable clinical benefits with a tolerable safety profile across various heavily pre-treated solid tumors, including non-small cell lung cancer (“NSCLC”), testicular cancer, and gastric cancer. Notably, the median progression-free survival exceeded six months, with approximately 30% of patients experiencing durable disease stabilization, even in cancers refractory to prior therapies such as pembrolizumab and nivolumab. Building on these results, a randomized, Phase 2 investigator-sponsored trial led by Dr. Yelena Janjigian at Memorial Sloan Kettering Cancer Center is actively enrolling. This trial aims to evaluate the clinical safety and efficacy of the combination of agenT-797, botensilimab (a novel Fc-enhanced CTLA-4 inhibitor), balstilimab (anti-PD-1), ramucirumab, and paclitaxel in patients with previously treated, advanced esophageal, gastric, or gastroesophageal junction adenocarcinoma. The study, which is expected to enroll approximately 38 patients with advanced, unresectable, or metastatic forms of these cancers, is a priority program for us. Encouraging activity was observed with agenT-797 in both monotherapy and combination settings, with durable responses and disease stabilization, as presented at the American Association for Cancer Research (“AACR”) and more recently at the Society for Immunotherapy of Cancer (“SITC”) conference in November 2023.
Current wording
Building on these results, a randomized, Phase 2 investigator-sponsored trial led by Dr. Yelena Janjigian at Memorial Sloan Kettering Cancer Center is actively enrolling patients with previously treated, advanced esophageal, gastric, or gastroesophageal junction adenocarcinoma. This study is evaluating a combination regimen of agenT-797, botensilimab (a novel Fc-enhanced CTLA-4 inhibitor), balstilimab (anti-PD-1), ramucirumab, and paclitaxel. The trial, expected to enroll approximately 38 patients with advanced, unresectable, or metastatic disease, is a strategic priority for the Company. The inclusion of agenT-797 in this regimen reflects growing clinical interest following the durable responses observed in Phase 1, including the Nature Oncogene complete and partial responder cases, and aims to determine whether similar benefits can be achieved in 2L gastric cancer. Encouraging activity for agenT-797 in both monotherapy and combination settings has been presented at major scientific meetings, including American Association for Cancer Research (“AACR”) and Society for Immunotherapy of Cancer (“SITC”) conferences.

Current wording
Interest income decreased $38,000 for the three months ended June 30, 2025, from income of $38,400 for the three months ended June 30, 2024 to income of $300 for the three months ended June 30, 2025, primarily due to interest expense accrued under our related party note (the “Note”) and decreased interest earned on our money market funds.
Previous wording
Research and development (“R&D”) expense includes the costs associated with our internal research and development activities, including compensation and benefits, occupancy costs, manufacturing costs, costs of expert consultants, and administrative costs. R&D expense decreased 51% to $1.3 million for the three months ended March 31, 2025 from $2.5 million for the three months ended March 31, 2024. This decrease is primarily due to decreased costs associated with both the timing of our clinical trials and pre-clinical activities, and decreased personnel costs, primarily due to decreased headcount.

Our cash and cash equivalents balance as of March 31, 2025 was $3.2 million. We believe that our cash and cash equivalents balance, plus anticipated funding, will be sufficient to satisfy our liquidity requirements for more than one year from when these financial statements were issued.
