A Study of GSK5764227 in Participants With Advanced Solid Tumors (EMBOLD)

Is NCT06551142 recruiting? Yes, currently enrolling (Sep 2026). This Phase 1 trial studies multiple treatments for neoplasms.

Phase 1RecruitingGlaxoSmithKlineNCT06551142Data as of Sep 2026Location: International · 13 countries

Treatment: Ris-Rez · Cisplatin · Carboplatin · Atezolizumab · Pembrolizumab · Durvalumab · Cetuximab · Bevacizumab · Tarlatamab · DostarlimabThe goal of this study is to assess the safety, tolerability, clinical activity and pharmacokinetics of Risvutatug rezetecan (Ris-Rez), also known as GSK5764227. The study will also see how the levels of Ris-Rez will change over time at different dose amounts when administered alone and in combination with other medicines like carboplatin, cisplatin, atezolizumab, pembrolizumab, durvalumab, bevacizumab, cetuximab, tarlatamab, dostarlimab
