Talazoparib & Thoracic RT for ES-SCLC

Status Recruiting

Clinical Trial Summary

This is a phase I, dose escalating study evaluating the safety of combining talazoparib and low dose consolidative thoracic radiotherapy for small cell lung cancer patients. This study will also determine the maximum tolerated dose (MTD) of talazoparib in combination with low dose thoracic radiotherapy. Patients will start on talazoparib on day 1 of study intervention, and will continue to orally take talazoparib until the last day of radiation therapy. Up to 24 patients will be enrolled to the study, where the first 3 patients will start with a starting dose level of talazoparib is 0.5 mg PO once daily. This will increase to 1mg daily with each new cohort.

Clinical Trial Description

This is a phase I, dose escalating study evaluating the safety of combination talazoparib and low dose consolidative thoracic radiotherapy for extensive-stage small cell lung cancer patients with at least stable disease after standard of care 4 - 6 cycles of chemotherapy (a platinum agent and etoposide). This study will also determine the maximum tolerated dose (MTD) of talazoparib in combination with low dose thoracic radiotherapy. Secondary objectives will be to examine clinical outcomes, including locoregional recurrence within the radiation field, progression-free survival, overall survival and acute/chronic toxicities up to 1 year. Patients will start on talazoparib on day 1 of study intervention, and will continue to orally take talazoparib until the last day of RT. Patient will start low dose RT on day 6-9, and will continue for 10 fractions throughout 2 weeks. Up to 24 patients will be enrolled to the study, where the first 3 patients will start with a starting dose level of talazoparib is 0.5 mg PO once daily. This will increase to 1mg daily with each new cohort. Patients will be monitored weekly during study treatment, and followed up at 3 weeks, and every 3 months after for 1 year. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
