Stomach Cancer

This is a first-in-human, Phase 1/2, open-label, dose escalation and dose expansion and combination study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of PT886.

Patients with the following tumor types will be eligible for screening: unresectable or metastatic gastric adenocarcinoma, gastroesophageal junction (GEJ) adenocarcinoma, and pancreatic ductal adenocarcinoma (PDAC).

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 442 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 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. Additionally, a drug-drug interactions substudy will investigate the potential for CGT9486 to be a CYP3A4 inducer in approximately 16 patients who have received at least one prior line of therapy for GIST.

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 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).

This study will enroll patients who have a diagnosis of locally advanced, unresectable or metastatic soft tissue or bone sarcoma (except gastrointestinal stromal tumors and Kaposi's sarcoma) from any site.
