Summary

This trial is testing a new drug called CFT8634 to see if it is safe and effective for patients with specific types of cancer who have no other treatment options. Researchers aim to find out if the drug can help reduce or control tumor growth.

Who is the study for?
This trial is for adults and adolescents with advanced or metastatic synovial sarcoma or SMARCB1-null tumors who have tried other treatments without success. They must be able to swallow capsules, have adequate organ function, and not be pregnant or planning pregnancy. Participants need measurable disease per RECIST v1.1 criteria and can't join if they've had certain recent surgeries, therapies, CNS involvement that's unstable, significant cardiac issues, HIV infection, or are taking drugs affecting CFT8634 metabolism.
What is being tested?
The study tests the safety and tolerability of a new drug called CFT8634 in patients with specific types of cancer that disrupt the SMARCB1 gene. It's an early-phase trial (Phase 1/2), meaning it's one of the first times this drug is being given to humans to see how safe it is and how well it works against these cancers.
What are the potential side effects?
While specific side effects for CFT8634 aren't listed here as it’s a first-in-human study, common side effects from similar cancer treatments may include nausea, fatigue, liver problems like increased enzymes indicating inflammation or damage; blood disorders such as low counts leading to higher infection risk; digestive issues; potential heart rhythm changes.

Trial Design

4Treatment groups
Experimental Treatment
Group I: Phase 2 - Arm B: CFT8634Experimental Treatment1 Intervention
Approximately 20 subjects with locally advanced or metastatic SMARCB1-null tumors at the RP2D having received ≥1 prior anticancer therapy
Group II: Phase 2 - Arm A: CFT8634Experimental Treatment1 Intervention
Approximately 30 subjects with locally advanced or metastatic synovial sarcoma at the recommended phase 2 dose (RP2D) having received 1-2 prior anticancer therapies
Group III: Dose Escalation Phase 1/Part1: CFT8634Experimental Treatment1 Intervention
Up to approximately 40 subjects ≥18 years of age or between ≥16 and \<18 years of age and weighing ≥50 kg with locally advanced or metastatic SMARCB1-perturbed cancers, including synovial sarcoma and SMARCB1-null tumors, having received ≥ 1 prior anticancer therapy
Group IV: Dose Escalation Phase 1/Part 2: CFT8634Experimental Treatment1 Intervention
Up to approximately 6-12 subjects ≥12 and \<16 years of age and weighing ≥40 kg or ≥16 and \<18 years of age and weighing ≥40 kg and \<50 kg with locally advanced or metastatic SMARCB1-perturbed cancers, including synovial sarcoma and SMARCB1-null tumors

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Synovial Sarcoma treatments typically include chemotherapy, radiation, and targeted therapies. Chemotherapy kills rapidly dividing cells, including cancer cells, while radiation therapy damages the DNA of cancer cells, leading to their death. Targeted therapies, such as tyrosine kinase inhibitors, focus on specific molecular abnormalities in cancer cells, sparing normal cells. The trial CFT8634 is investigating a new treatment, likely with a novel mechanism of action, which could provide more effective and less toxic options. Understanding these mechanisms helps in selecting the best treatment strategy, improving outcomes and minimizing side effects for patients.
