Tempest Therapeutics ( (TPST) ) has shared an announcement.

On February 25, 2026, Tempest Therapeutics reported interim data from the ongoing REDEEM-1 Phase 1/2a trial of TPST-2003, an autologous CD19/BCMA dual-targeting CAR-T therapy for relapsed/refractory multiple myeloma, alongside results from a prior investigator-initiated trial. As of late January 2026, all six efficacy-evaluable REDEEM-1 patients achieved complete responses, the combined overall response rate across both studies was 100% in 25 evaluable patients, safety was favorable with no Grade 3 or higher CRS or ICANS, and prior data showed a median progression-free survival of 23.1 months, prompting Tempest to accelerate TPST-2003’s development, present expanded data later in 2026, and prepare for a potential U.S. registrational study while also positioning its parallel dual-targeting CAR platform for broader oncology and immunology indications.

Spark’s Take on TPST Stock

According to Spark, TipRanks’ AI Analyst, TPST is a Neutral.

The score is primarily held down by weak financial performance (no revenue, ongoing losses, and significant cash burn with a shrinking equity cushion). Technicals remain soft with price below key longer-term averages and negative MACD. Corporate events are mixed (Nasdaq compliance risk vs. governance approvals), and valuation metrics offer limited support due to negative earnings and no dividend.
