Summary

This trial is testing peposertib, in combination with avelumab and hypofractionated radiation therapy, as a potential new treatment for patients with solid tumors and hepatobiliary malignancies.

Who is the study for?
Adults with advanced/metastatic solid tumors or hepatobiliary malignancies, who have tried standard treatments without success or declined them. They must be in relatively good health (ECOG <=2), have measurable cancer lesions, and agree to biopsies if needed. Pregnant women, those with certain psychiatric illnesses, uncontrolled diseases, recent live vaccinations, or on strong immune system drugs can't join.
What is being tested?
The trial is testing Peposertib combined with Avelumab and hypofractionated radiation therapy against advanced cancers. It aims to find the best dose of Peposertib and see how well it works alongside an immunotherapy drug (Avelumab) and a type of intense short-term radiation treatment.
What are the potential side effects?
Possible side effects include reactions related to the immune system attacking normal cells as well as typical chemotherapy effects like fatigue, digestive issues, skin reactions from radiation therapy. Specific organ inflammation such as pneumonitis may occur due to either medication.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Arm B (hypofractionated RT, peposertib, avelumab)Experimental Treatment5 Interventions
Patients undergo 8 fractions of hypofractionated RT QD on days -17 to -7. Patients also receive peposertib PO BID on days 1-28, and avelumab IV over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo biopsy, CT, and collection of blood on the trial.
Group II: Arm A (hypofractionated RT, avelumab)Active Control5 Interventions
Patients undergo 8 fractions of hypofractionated RT QD on days -17 to -7. Patients also receive avelumab IV over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo biopsy, CT, and collection of blood on the trial.
