A Study of Ziftomenib, an Oral Menin Inhibitor, in Combination With Imatinib in Patients With Advanced Gastrointestinal Stromal Tumors (GIST)

Purpose

In this clinical trial, the safety, tolerability, and preliminary antitumor activity of ziftomenib in combination with imatinib will be evaluated in adults with gastrointestinal stromal tumors (GIST) who have been treated previously with imatinib.

  • Gastrointestinal Stromal Tumor (GIST) of the Gastrointestinal Tract
  • Gastrointestinal Stromal Cancer
  • Gastrointestinal Stromal Neoplasm
  • Gastrointestinal Stromal Tumor, Malignant
  • Gastrointestinal Stromal Cell Tumors

Inclusion Criteria

  • Documented diagnosis of advanced or metastatic KIT mutant GIST. - Documented disease progression on imatinib therapy as current or prior treatment. - Eastern Cooperative Oncology Group (ECOG) performance status (PS) of ≤2 at screening. - At least 1 measurable lesion per mRECIST. - Negative pregnancy test for female patients of childbearing potential. - Adequate organ function per protocol requirements. - Resolution of all clinically significant toxicities from prior therapy to ≤Grade 1 (or patient baseline) within 1 week prior to the first dose of study drug. - Participant, or legally authorized representative, must be able to understand and provide written informed consent prior to the first screening procedure.

Exclusion Criteria

  • Diagnosis of non-KIT mutation or a T670X KIT mutation-driven GIST. - History of prior or currently has cancer which has potential to interfere with obtaining study results. - Received a prohibited medication, including investigational therapy, less than 14 days or within 5 drug half-lives prior to the first dose of study intervention. - Active central nervous system metastases. - Uncontrolled intercurrent illness, including, but not limited to protocol defined cardiac disease. - Mean corrected QT interval (QTcF) greater than 470ms. - Left ventricular ejection fraction (LVEF) <50%. - Major surgery within 2 weeks prior to the first dose of study intervention. - Is pregnant or lactating. - Gastrointestinal abnormalities that may impact taking study intervention by mouth. - Actively bleeding, excluding hemorrhoidal or gum bleeding.
