A Study to Investigate Velzatinib Compared With Imatinib in Adult Participants With Previously Untreated Metastatic and/or Unresectable Gastrointestinal Stromal Tumors (StrateGIST Frontline)
800 participantsStarted 2026-06-15
Plain-language summary
Gastrointestinal Stromal Tumour (GIST) is a soft tissue tumour that develops in the digestive system, most often in the stomach or small intestine. It is caused by changes in certain proteins that cause the cells to grow uncontrollably. Although current treatments may be effective, tumours may stop responding over time, highlighting the need for newer options. This study is evaluating velzatinib (GSK6042981) in participants with newly diagnosed GIST that has spread or cannot be surgically removed. Velzatinib will be compared with imatinib, the standard treatment, to assess whether it can delay disease worsening and is safe and well tolerated.

Inclusion criteria
. Those of non-childbearing potential are eligible without additional contraception.
. Those of childbearing potential must use an acceptable, highly effective contraceptive method and have a negative pregnancy test before starting the study. The investigator will assess their pregnancy risk.
Exclusion criteria
. Has documented evidence of plasma HIV-1 ribonucleic acid (RNA) ≥50 c/mL within 3 months prior to or at screening. In the 3 to 12 months prior to screening, plasma HIV 1 RNA levels consistently \<50 c/mL are required for enrollment; if multiple instances of plasma HIV-1 RNA values ≥50 c/mL occurred in the 3 to 12 months prior to screening, the participant is not eligible for enrollment unless, per the investigator's assessment, the elevations were neither persistent nor associated with antiretroviral resistance; OR
. Has not had CD4 cell counts measured in the past 12 months (i.e., at least two separate measurements taken a minimum of 28 days apart, one of which must be conducted at screening); OR
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Progression-Free Survival (PFS) as assessed by Blinded independent central review (BICR)
. Has had any CD4 cell count values ≤200 cells/mm3 in the past 12 months; OR
. Has had one or more changes in their combination antiretroviral therapy regimen (except for switches as allowed per details provided in protocol) or has received an antiretroviral therapy regimen that is inconsistent with locally recommended guidelines during the 3 months prior to screening; OR
. Has a history of HIV-associated non-Hodgkin lymphoma within 5 years prior to screening or a history of HIV-associated invasive cervical cancer; OR
. Has received treatment with an HIV 1 immunotherapeutic vaccine within 90 days of screening.
