Study Endpoints

Primary Endpoints

Confirmed Objective Response Rate (ORR)
Up to approximately 22 months

Confirmed ORR is defined as the proportion of participants who have achieved best overall response (BOR) of confirmed complete response (CR) or partial response (PR) as assessed by investigator, according to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)

Phase 0: Total, Cleaved, and Unbound GSK5757810 Payload Concentration in Tumor Tissue
Intraoperatively

The total, cleaved, and unbound GSK5757810 payload concentration in Gd enhancing and Gd non-enhancing tumor tissue collected during Phase 0 surgery from participants with rGBM, and Gd enhancing tumor tissue collected during Phase 0 surgery from participants with brain metastases, will be determined.

Phase 1: Incidence of Adverse Events as Assessed by CTCAE v5.0
Date of first infusion until 90-days post last infusion

Incidence of the following will be summarized: AEs, SAEs, and AEs of Special Interest (AESIs); treatment discontinuations, dose interruptions, and dose reductions due to AEs; changes in vital signs, body weight, laboratory tests, ECG, and ECOG performance status

Secondary Endpoints

Unconfirmed ORR
Up to approximately 37 months
Duration of Response (DoR)
Up to approximately 37 months
Progression Free Survival (PFS)
Up to approximately 37 months

Frequently asked questions about Risvutatug Rezetecan

What is Risvutatug Rezetecan used for?

Risvutatug Rezetecan is an investigational monoclonal antibody being studied for gastrointestinal neoplasms and glioblastoma (GBM). It is in Phase 1 clinical development for these oncology indications, including advanced gastrointestinal cancers that cannot be surgically removed and recurrent grade 4 glioma.

What does Risvutatug Rezetecan target?

Risvutatug Rezetecan targets B7-H3, a protein expressed on tumor cells. It is designed as a B7-H3-targeted antibody-drug conjugate (ADC) that delivers a cytotoxic payload to cancer cells expressing this target.

Who makes Risvutatug Rezetecan?

Risvutatug Rezetecan is being developed by GSK plc, a biopharmaceutical company listed on the stock exchange under the ticker GSK.

What phase is Risvutatug Rezetecan in?

Risvutatug Rezetecan is in Phase 1 clinical development. It is an investigational drug and has not been approved by regulatory authorities. It is currently being evaluated in early-stage clinical trials for gastrointestinal cancers and glioblastoma.

What clinical trials is Risvutatug Rezetecan in?

Risvutatug Rezetecan is being studied in two recruiting trials. NCT06885034 is a Phase 1 study of GSK5764227 alone or with other treatments in advanced gastrointestinal cancers, enrolling 451 participants across multiple countries. NCT07268053 is a Phase 0/1 trial in recurrent grade 4 glioma and brain metastases, enrolling 15 participants in the United States.

Is Risvutatug Rezetecan the same as GSK5764227?

Yes, Risvutatug Rezetecan is also known as GSK5764227. Clinical trial records use the GSK5764227 name to refer to this B7-H3-targeted antibody-drug conjugate.
