AI OverviewAI overview is shown in English only.

Jasper Therapeutics Inc. (JSPR) is a clinical-stage biotechnology company focused on developing therapeutics for mast cell driven diseases and immune-mediated disorders, with a lead program in briquilimab for severe combined immunodeficiency (SCID) and a pipeline including assets from the recent Kira Pharmaceuticals acquisition.

  • Lead product candidate briquilimab is a monoclonal antibody targeting the CD117 (KIT) receptor, with Orphan Drug, Fast Track, and Rare Pediatric Disease Designations for SCID [sec_mda · as of 2026-08-14].
  • Acquired Kira Pharmaceuticals in July 2026, adding KP-104 (Phase 2/3 ready bifunctional complement inhibitor) and KP-701 (preclinical anti-CD79BxCD32B antibody) to the pipeline [sec_mda · as of 2026-08-14].
  • Cash & equivalents of $7.3M as of 2026-06-30, with net income of -$2.8M and shareholders' equity of $1.4M [sec].
  • Completed a PIPE financing in July 2026 raising $132M in gross proceeds from issuance of non-voting convertible preferred stock [news · published 2026-08-14].
  • Expects to announce next steps for briquilimab in SCID in the first quarter of 2027, following a pre-BLA meeting with the FDA [sec_mda · as of 2026-08-14].

What works

  • Briquilimab has received Orphan Drug, Fast Track, and Rare Pediatric Disease Designations in SCID, potentially qualifying for a priority review voucher [sec_mda · as of 2026-08-14].
  • The Kira acquisition added a Phase 2/3 ready asset (KP-104) and a preclinical asset (KP-701), broadening the pipeline beyond mast cell indications [sec_mda · as of 2026-08-14].
  • The company raised $132M in gross proceeds from a PIPE financing concurrent with the Kira acquisition, providing capital to advance programs [news · published 2026-08-14].

What to weigh

  • Cash & equivalents were only $7.3M as of 2026-06-30, with a net loss of $2.8M and shareholders' equity of $1.4M, indicating a tight cash position before the July PIPE [sec].
  • The company has incurred significant losses and negative cash flows from operations since inception [sec_mda · as of 2026-05-14].
  • A workforce reduction of approximately 50% was implemented in July 2025 to extend cash runway, reflecting prior financial strain [sec_mda · as of 2026-03-30].
  • Briquilimab's clinical development in mast cell diseases (CSU, CIndU) is still in earlier stages, with no approved products yet [sec_mda · as of 2026-08-14].

Risks & what to watch (4)›

Key risks

  • Low cash runway pre-PIPE — Cash & equivalents of $7.3M as of 2026-06-30, with net loss of $2.8M, suggests limited liquidity before the July PIPE [sec].
  • No approved products — All programs are clinical or preclinical; no revenue from product sales, relying on financing and partnerships [sec_mda · as of 2026-08-14].
  • Workforce reduction history — A ~50% workforce reduction in July 2025 indicates prior financial distress and potential impact on operations [sec_mda · as of 2026-03-30].
  • Regulatory dependency — Briquilimab's next steps depend on FDA pre-BLA meeting outcome; any delay or negative feedback could affect timeline [sec_mda · as of 2026-08-14].

What to watch

  • Pre-BLA meeting with FDA for briquilimab in SCID and announcement of next steps expected in Q1 2027 [sec_mda · as of 2026-08-14].
  • Update on clinical development in mast cell mediated diseases expected in the second half of 2026 [sec_mda · as of 2026-08-14].
  • Progress of KP-104 Phase 2 basket trial in rare renal indications (IgAN) [sec_mda · as of 2026-08-14].
  • Potential monetization of a priority review voucher if FDA issues one for briquilimab by December 31, 2028, triggering a $30M CVR payment [sec_mda · as of 2026-08-14].
