RECRUITING

A Study of an FGFR2/3 Inhibitor (CGT4859) in Patients With Cholangiocarcinoma and Other Advanced Solid Tumors

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is an open-label, phase 1/2 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 CGT4859 in adult participants with intrahepatic cholangiocarcinoma (iCCA) or other advanced solid tumors with FGFR2 and/or FGFR3 genetic alternations.

Official Title

A Phase 1/2 Study of a Selective FGFR2/3 Inhibitor, CGT4859, in Patients With Cholangiocarcinoma and Other Advanced Solid Tumors Harboring FGFR2 and/or FGFR3 Genetic Alterations

Inclusion Criteria	Exclusion Criteria
1. Histologically confirmed locally advanced, metastatic, and/or unresectable iCCA or other solid tumor with documented FGFR2/3 alteration in blood and/or tumor. 2. Previously treated with, not appropriate for, or declined standard-of-care first-line treatment. 3. Have measurable disease per RECIST v1.1. 4. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. 5. Have clinically acceptable local laboratory screening results (clinical chemistry and hematology) within certain limits.	1. Received chemotherapy or anticancer therapies or radiotherapy within certain timeframes before first dose of study drug. 2. Major surgeries (eg, abdominal laparotomy) within 4 weeks of the first dose of study drug. 3. Clinically significant corneal or retinal disorders or current evidence of retinal detachment. 4. Resolution of toxicities from prior therapy to ≤Grade 1 (or baseline), including resolution of clinically significant laboratory abnormalities, before the first dose of study drug. Exceptions are alopecia, hypothyroidism, or type 1 diabetes mellitus controlled with medical intervention, and paronychia controlled with local intervention. 5. Received more than 2 prior FGFRi therapies 6. Active, symptomatic, or untreated brain metastases unless the participant is clinically stable and off corticosteroids for ≥2 months.
