What this Trial Is About

Researchers are studying CT7439, an experimental drug, in adults with locally advanced or metastatic solid cancers to assess its safety and tolerability. This Phase 1/2, modular, multi-part study focuses on first-in-human dose escalation to find the appropriate doses when given alone or combined with other anticancer treatments. The study aims to identify the minimum biologically active dose and maximum tolerated or feasible dose of CT7439. Participants will receive CT7439 capsules by mouth once daily, starting with a single 1 mg dose followed by a treatment-free period before continuous dosing in 28-day cycles. Dose escalation cohorts will be sequentially evaluated, with up to six cohorts planned. Participants will continue treatment until disease progression, unacceptable side effects, withdrawal, or study completion. Further cohorts may be added to explore specific patient subgroups. During the study, participants will undergo regular safety and health assessments, including monitoring of vital signs, blood tests, ECGs, and tumor imaging using CT or MRI. Researchers will track treatment side effects and measure drug levels in the blood and urine. The study includes monitoring from the first dose through multiple 28-day cycles, with follow-up visits after treatment ends to evaluate overall response, progression-free survival, and other safety outcomes.

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Treatment

Duration - Up to 6 cycles of 28 days each, continuing until disease progression or unacceptable toxicities

Participants receive CT7439 capsules by mouth once daily in cycles of 28 days. The initial dose is followed by a minimum 48-hour treatment-free period before continuous daily dosing. Treatment continues until disease progression, unacceptable toxicities, withdrawal, or study completion.

Multiple visits including baseline and frequent monitoring visits during treatment cycles (Cycle 0 Day 1 and 2; Cycle 1 Days 1, 8, 15; Cycle 2 Days 1, 15; and Cycle 3 to Cycle 6 Day 1)

Follow-up

Duration - 30 days after last dose

Participants are monitored for safety and treatment outcomes for 30 days after the last dose of CT7439.

1 visit within 30 days after last dose
