PEEL-224, Vincristine and Temozolomide in Pediatric Solid Tumors

Is NCT06721689 recruiting? Yes, currently enrolling (Sep 2026). This Phase 1/2 trial studies multiple treatments including PEEL-224 and Vincristine for refractory solid tumors.

Phase 1/2RecruitingTheodore LaetschNCT06721689Data as of Sep 2026

Treatment: PEEL-224 · Vincristine · Temozolomide (TMZ)The phase 1 primary objective is to determine the pediatric recommended phase 2 dose (RP2D) of PEEL-224 as a single agent (phase 1A) and in combination with vincristine and temozolomide (phase 1B). The phase 2 primary objective is to estimate the objective response rate (ORR) in children with refractory, progressive and relapsed NBL and rhabdomyosarcoma (RMS) treated with the RP2D of PEEL-224 in combination with vincristine and temozolomide.
