• Positive FDA Feedback for SENTI-202 Pivotal Trial

  Senti Bio received positive feedback from the FDA regarding its Regenerative Medicine Advanced Therapy (RMAT) designated SENTI-202 program, allowing for a single-arm, multi-center pivotal trial for potential registration in Relapsed/Refractory Acute Myeloid Leukemia (R/R AML).

• SENTI-202 Efficacy Optimized with 'Donor X' Attribute

  The company identified a specific 'Donor X' attribute that correlates with improved efficacy for SENTI-202, with 50% of patients achieving a composite CR (cCR) when receiving doses from Donor X-characteristic derived NK cells. All future manufacturing will utilize this attribute.

• Q1 Cash Burn Significantly Reduced

  Net cash used in operating activities for Q1 2026 was $7.5 million, a substantial reduction from $14.1 million in Q1 2025, reflecting continued operational streamlining and cost control efforts.

This filing provides critical updates on Senti Bio's lead asset, SENTI-202, and its financial stability. Positive FDA feedback for a single-arm pivotal trial significantly de-risks the clinical path for SENTI-202 in R/R AML. The identification of a 'Donor X' attribute to optimize efficacy further strengthens the program. Financially, the company reported a substantially reduced cash burn in Q1 2026 and confirmed the imminent closing of the initial $10 million tranche of its previously announced $40 million strategic financing. These developments are crucial for a company that recently disclosed a going concern warning and a limited cash runway, providing a lifeline and a clearer path forward for its key therapeutic candidate.
