New drug velzatinib tested for Hard-to-Treat stomach and intestinal tumors
NCT ID NCT07689201
First seen Jul 08, 2026 · Last updated Sep 09, 2026 · Updated 2 times
Summary
This phase 2 trial tests the drug velzatinib in people with advanced gastrointestinal stromal tumors (GIST) that have stopped responding to or cannot tolerate several standard treatments. The study aims to see if velzatinib can shrink or control the tumors and how safe it is. Participants receive velzatinib and are monitored for tumor response and side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- velzatinib (GSK6042981)
- What this could lead to
- If velzatinib shrinks or controls tumors, it could offer a new treatment option for people with advanced GIST who have run out of standard therapies.
- What could go wrong
- This is a small, early-phase study (24 participants) with no comparison group. The drug may not work or may cause side effects, and results may not apply to all GIST patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Histologically or cytologically confirmed GIST that is metastatic and/or surgically unresectable. * Documented disease progression on or intolerance to imatinib, sunitinib, regorafenib, and pimitespib. * Documented mutation status of KIT and/or PDGFRA. * Tumor tissue may be available for retrospective biomarker analysis. The sample may be from archival tissue or a new biopsy. Investigators may consult with the sponsor regarding the enrolment of participants for whom archival tissue is no longer available and who are not eligible to undergo a new biopsy. * Is willing to use adequate contraception male and/or female participants. Exclusion Criteria: * Known untreated or active central nervous system metastases. * Has significant, uncontrolled, or active cardiovascular disease. * Participants with a known allergy or hypersensitivity to any component of velzatinib. Participants with a history of Stevens-Johnson syndrome on a prior Tyrosine kinase inhibitor (TKI) are excluded. * 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 metastatic disease. * Prior treatment with ripretinib or other investigational agents that are currently under clinical development for GIST. * Is pregnant or breastfeeding. * Any condition or illness that, in the opinion of the Investigator, might compromise participant safety or interfere with the evaluation of the safety of the study treatment.
