MC1R-targeted Alpha-particle Monotherapy and Combination Therapy Trial With Nivolumab in Adults With Advanced Melanoma

Is NCT05655312 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies multiple treatments including [203Pb]VMT01 and [212Pb]VMT01 for recurrent melanoma (skin).

Phase 1/2RecruitingPerspective TherapeuticsNCT05655312Data as of May 2026

Treatment: [203Pb]VMT01 · [212Pb]VMT01 · NivolumabIn this first-in human, phase I/IIa study, the safety and efficacy of \[212Pb\]VMT01, an alpha-particle emitting therapeutic agent targeted to melanocortin sub-type 1 receptor (MC1R) is being evaluated as a monotherapy and in combination with nivolumab in subjects with unresectable and metastatic melanoma.
