A Study to Investigate Velzatinib Compared With Imatinib in Adult Participants With Previously Untreated Metastatic and/or Unresectable Gastrointestinal Stromal Tumors (StrateGIST Frontline)

2026年8月17日 更新者：GlaxoSmithKline

A Phase 3, Randomized, Multicenter, Open-Label Study of Velzatinib (GSK6042981) Versus Imatinib in Participants With Previously Untreated Metastatic and/or Unresectable Gastrointestinal Stromal Tumors (GIST)

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.

    1. Those of non-childbearing potential are eligible without additional contraception.
    2. 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.

    3. Has had any CD4 cell count values ≤200 cells/mm3 in the past 12 months; OR
    4. 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
    5. 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
    6. Has received treatment with an HIV 1 immunotherapeutic vaccine within 90 days of screening.
  • Is pregnant or breastfeeding.
  • Is unable to adhere to the protocol, including requirements for the Follow-up Period of the study.
  • Has an alanine aminotransferase (ALT) value >2.5x upper limit of normal (ULN) or (for participants with documented liver metastases/tumor infiltration) has an ALT value >5x ULN
  • Has a total bilirubin value >1.5x ULN.
  • Has cirrhosis or current unstable liver or biliary disease per investigator assessment defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal/gastric varices, or persistent jaundice.
  • Evidence of chronic hepatitis B virus (HBV) infection with detectable viral load despite antiviral therapy with high resistance barrier.
  • 12-lead electrocardiogram (ECG) demonstrating mean QT interval corrected (QTc) corrected by Fridericia's formula >480msec at screening or history of long QT syndrome.
