Recent Corporate Highlights and Upcoming Milestones

  • INBRX-106
    • In May 2026, we announced updated interim data from our randomized, first-line Phase 2 portion of the HexAgon study. The trial evaluated the safety and efficacy of INBRX-106, a hexavalent OX40 agonist, in combination with pembrolizumab (the combination arm) versus pembrolizumab monotherapy (the control arm) in first-line patients with treatment-naïve, PD-L1 positive (Combined Positive Score (CPS) ≥ 20) metastatic or unresectable recurrent Head and Neck Squamous Cell Carcinoma (HNSCC).
    • We plan to announce progression-free survival (PFS) data from the randomized Phase 2 trial in HNSCC in combination with pembrolizumab in the fourth quarter of 2026.
  • ozekibart (INBRX-109)
    • In April 2026, we announced updated interim data from our Phase 1/2 study evaluating ozekibart (INBRX-109) in combination with FOLFIRI in patients with locally advanced or metastatic, unresectable colorectal cancer (CRC);
    • Additionally, in April 2026, we submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for ozekibart in conventional chondrosarcoma; and
    • We plan to meet with the FDA in the second half of 2026 to discuss plans to initiate a first-line registrational trial in CRC. We also plan to discuss with the FDA the potential for accelerated regulatory pathways for ozekibart in fourth-line colorectal cancer and in refractory Ewing sarcoma.

Financial Results

  • Cash and Cash Equivalents. As of March 31, 2026, the Company had cash and cash equivalents of $161.7 million, as compared to $124.2 million as of December 31, 2025. The Company's cash balance increased as a result of the receipt of gross proceeds of $75.0 million in March 2026 upon entering into the First Amendment to the Loan and Security Agreement (March 2026 Amendment) with Oxford Finance LLC (Oxford).
  • R&D Expense. Research and development expenses were $25.2 million for the first quarter of 2026, as compared to $36.9 million for the first quarter of 2025. This decrease was primarily related to lower clinical trial costs associated with ozekibart for the treatment of unresectable or metastatic conventional chondrosarcoma as the trial approached completion of enrollment, as well as a decrease in contract manufacturing expenses due to the timing and completion of certain manufacturing activities required to support our clinical trials. In addition, personnel-related expenses decreased as a result of a decrease in headcount in the current period. 
  • G&A Expense . General and administrative expenses were $5.7 million during the first quarter of 2026, compared to $6.0 million during the first quarter of 2025. These expenses were consistent in each period with a slight decrease in personnel-related expenses as a result of a decrease in headcount in the current period.
  • Other Expense, Net. Other expense, net was $2.5 million during the first quarter of 2026, compared to $0.4 million during the first quarter of 2025. The increase reflects higher interest expense following the Company's receipt of an additional $75.0 million in principal, bringing the outstanding loan balance from $100.0 million to $175.0 million during the first quarter of 2026, as well as lower interest income on the Company's cash and money market balances reflecting lower average cash balances and a decline in short-term interest rates.
  • Net Loss. Net loss was $33.4 million during the first quarter of 2026, or $2.15 per share, basic and diluted, as compared to a net loss of $43.3 million during the first quarter of 2025, or $2.80 per share, basic and diluted.
