Clinical trials

This is an open-label, two-part Phase 2 study investigating CGT9486 for the treatment of patients with Advanced Systemic Mastocytosis (AdvSM), including patients with Aggressive SM (ASM), SM with Associated Hematologic Neoplasm (SM-AHN), and Mast Cell Leukemia (MCL).

The purpose of this expanded access program (EAP) is to provide investigational bezuclastinib so that it can be coadministered with sunitinib to patients with a diagnosis of gastrointestinal stromal tumors (GIST) with no comparable or satisfactory alternative therapy options. The combination of bezuclastinib and sunitinib provides broad inhibition of all primary and secondary KIT mutations that commonly occur in GIST.

The purpose of this expanded access program (EAP) protocol is to provide investigational bezuclastinib to patients with a diagnosis of nonadvanced systemic mastocytosis (NonAdvSM) or advanced systemic mastocytosis (AdvSM) who have received and failed or been intolerant to at least one standard approved therapy and/or have no comparable or satisfactory alternative therapy options.

This is a Phase 1, two-part, open-label, nonrandomized, dose-escalation and signal-seeking study of CGT6297, evaluating the safety, tolerability, PK, pharmacodynamic (what the drug does to the body), and antitumor activity of CGT6297 in adult participants with advanced solid tumors harboring PIK3CA mutations

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 an open-label, phase 1/1b study evaluating the safety, tolerability, pharmacokinetic (what the body does to the drug), pharmacodynamic (what the drug does to the body), and antitumor activity of CGT4255 in adult participants with advanced solid tumors with ERBB2 alterations or HER2 overexpression.
