Rinatabart Sesutecan (Rina-S, PRO1184, GEN1184) for Advanced Solid Tumors (GCT1184-01/ PRO1184-001)

Официальное название

Phase 1/2 Study of Rina-S in Patients With Locally Advanced and/or Metastatic Solid Tumors

Обзор

This study will test the safety, including side effects, and determine the characteristics of a drug called Rina-S in participants with solid tumors. Participants will have solid tumor cancer that has spread through the body (metastatic) or cannot be removed with surgery (unresectable).

Подробное описание

This is a Phase 1/2 study of Rina-S; also known as GEN1184, formerly known as PRO1184, a folate receptor alpha (FRα) targeted antibody-drug conjugate, to evaluate the safety, tolerability, pharmacokinetics (PK), and antitumor activity of Rina-S in participants with selected locally advanced and/or metastatic solid tumors, including epithelial ovarian cancer, endometrial cancer, breast cancer, non-small cell lung cancer, and mesothelioma.

The study consists of multiple parts:

Part A: monotherapy cohorts

Part B: tumor-specific monotherapy dose-expansion cohorts

Part C: platinum-resistant ovarian cancer (PROC) monotherapy cohort

Part D: combination therapy cohorts

Part E: a monotherapy PROC cohort

Parts F and G: a monotherapy endometrial cancer (EC) cohort

Part H: a monotherapy PROC cohort

Part I: platinum-sensitive ovarian cancer (PSOC) cohort

Part J: a monotherapy PROC cohort

Part K: a monotherapy high-grade ovarian cancer cohort

Participants will continue to receive study treatment until the first instance of disease progression, unacceptable toxicity, investigator decision, consent withdrawal, study termination by the Sponsor, pregnancy, or death.
