NCT07277270 · GlaxoSmithKline
A Study of GSK5764227 in Combination With Standard of Care (SoC) or Other Agents in Participants With Advanced Solid Tumors
What this study is about
The goal of this clinical trial is to test a new medicine called GSK5764227, which delivers a toxin directly to cancer cells to destroy them while sparing healthy cells. The study will combine GSK5764227 with standard treatments to evaluate its safety, examine how the body processes it, check if it triggers any immune responses, and assess whether it can shrink or control cancer.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Has an ECOG performance status of 0 or 1, with no deterioration in the 2 weeks before first dose.
- Has adequate organ function.
- Has histologically confirmed unresectable adenocarcinoma or unresectable metastatic adenocarcinoma of the colon or rectum. (Cohort A)
- Histologically or cytologically confirmed adenocarcinoma of the prostate (Cohort B)
Exclusion criteria
- Has a malignancy (except disease under study) that has progressed or required active treatment within the past 24 months except for basal cell or squamous cell carcinomas of the skin or in-situ carcinomas \[e.g., breast, cervix, bladder\] that have been resected with no evidence of disease.
- Has had any major surgery within 28 days prior to first dose.
- Has clinically significant bleeding symptoms or significant bleeding tendency within 1 month prior to the first dose.
- Has serious infection within 4 weeks prior to the first dose,
- Has untreated brain or central nervous system (CNS) metastases or brain/CNS metastases that have progressed
- Any evidence of current interstitial lung disease (ILD) or pneumonitis OR a prior history of ILD requiring high-dose glucocorticoids or non-infectious pneumonitis requiring high-dose glucocorticoids.
- Has a history of autoimmune disease that has required systemic treatments in the 2 years prior to screening.
- Has received immunosuppressive agents within 30 days prior to first dose of study intervention (or requires long-term \[30 days or longer\]). Low-dose corticosteroids (prednisone ≤10 milligrams (mg)/day or equivalent) may be administered.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
