vTv Therapeutics, Inc. Class A (NASDAQ:VTVT) reached two clinical milestones, finishing patient enrollment for its Phase 3 CATT1 study of cadisegliatin in type 1 diabetes while securing FDA orphan drug status for HPPD, an investigational sickle cell treatment. The stock rose 3.66% to $31.18 following the updates.

Completing enrollment in the CATT1 trial with 166 patients brings the company closer to evaluating cadisegliatin in late-stage testing for type 1 diabetes. Meanwhile, orphan drug designation for HPPD provides regulatory incentives for the oral Nrf2/Bach1 modulator, which showed positive preclinical results including increased fetal hemoglobin and reduced cell sickling.

Investors will look ahead to mid-2027, when the company expects to release topline data from the Phase 3 CATT1 trial. Further updates on the clinical development path for HPPD will also be key monitoring points.
