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.

A022102 Randomized Phase III trial of mFOLFIRINOX +/- Nivolumab vs. FOLFOX +/- Nivolumab for First-Line Treatment of Metastatic HER2-Negative Gastroesophageal Adenocarcinoma

Cancer Internal Medicine Stomach Cancer Adult Subjects

This phase III trial compares the effect of modified fluorouracil, leucovorin calcium, oxaliplatin, and irinotecan (mFOLFIRINOX) with or without nivolumab to the effect of modified fluorouracil, leucovorin calcium, and oxaliplatin (mFOLFOX) with or without nivolumab for the treatment of patients with advanced, unresectable, or metastatic HER2 negative esophageal, gastroesophageal junction, or gastric adenocarcinoma. The usual approach for patients who are not in a study is treatment with FOLFOX with some receiving an immunotherapy drug, either nivolumab or pembrolizumab, in addition to FOLFOX chemotherapy. The usual approach is defined as care most people get for cancer in the stomach, esophagus, or gastroesophageal junction. Fluorouracil is in a class of medications called antimetabolites. It stops cells from making DNA and may kill tumor cells. Leucovorin in a class of medications called folic acid analogs. When used with fluorouracil it enhances the effects of this chemotherapy drug. Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It blocks a certain enzyme needed for cell division and DNA repair, and may kill cancer cells. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill cancer cells. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Some patients on this trial will receive nivolumab, in addition to mFOLFOX or mFOLFIRINOX chemotherapy. mFOLFIRINOX with or without nivolumab may be more effective than mFOLFOX with or without nivolumab by shrinking the tumor in patients with advanced, unresectable, or metastatic HER2-negative esophageal, gastroesophageal junction, or gastric adenocarcinoma.

(PEAK) A PHASE 3 RANDOMIZED, OPEN-LABEL, MULTICENTER CLINICAL STUDY OF CGT9486+SUNITINIB VS SUNITINIB IN SUBJECTS WITH LOCALLY ADVANCED, UNRESECTABLE, OR METASTATIC GASTROINTESTINAL STROMAL TUMORS

Cancer Internal Medicine Stomach Cancer Adult Subjects Female Subjects Male Subjects

This is a Phase 3, open-label, international, multicenter study of CGT9486 in combination with sunitinib. This is a multi-part study that will enroll approximately 482 patients. Part 1 consists of two evaluations: 1) confirming the dose of an updated formulation of CGT9486 to be used in subsequent parts in approximately 20 patients who have received at least one prior line of therapy for Gastrointestinal Stromal Tumors (GIST) and 2) evaluating the potential for drug-drug interactions between CGT9486 and sunitinib in approximately 18 patients who have received at least two prior tyrosine kinase inhibitors (TKIs) for GISTs. The second part of the study will enroll approximately 388 patients who are intolerant to, or who failed prior treatment with imatinib only and will compare the efficacy of CGT9486 plus sunitinib to sunitinib alone with patients being randomized in a 1:1 manner. This study also contains two substudies: 1) a drug-drug interactions (DDI) substudy will investigate the potential for CGT9486 to be a Cytochrome P450 (CYP)3A4 inducer in approximately 16 patients who have received at least one prior line of therapy for GIST and 2) a substudy intended to test the efficacy of bezuclastinib and sunitinib as first-line (1L) treatment of GIST in approximately 40 participants with KIT exon 9 mutations and no prior systemic therapy (with the exception of up to 10 subjects with ongoing imatinib therapy of ≤4 weeks).

This is a study to evaluate the efficacy and safety of belzutifan monotherapy in participants with advanced pheochromocytoma/paraganglioma (PPGL), pancreatic neuroendocrine tumor (pNET), von Hippel-Lindau (VHL) disease-associated tumors, advanced wt (wild-type) gastrointestinal stromal tumor (wt GIST), or advanced solid tumors with hypoxia inducible factor-2 alpha (HIF-2α) related genetic alterations. The primary objective of the study is to evaluate the objective response rate (ORR) of belzutifan per response evaluation criteria in solid tumors version 1.1 (RECIST 1.1) by blinded independent central review (BICR).
