Summary

This trial aims to test the safety and effectiveness of a drug called CRB-601 in combination with immunotherapy or radiotherapy in patients with advanced solid tumors who have run out of treatment options. The

Who is the study for?
This trial is for patients with advanced solid tumors who have tried all other treatments. It's aimed at those whose cancers express a specific protein, avb8 integrin. Participants will receive the experimental drug CRB-601, alone or with immunotherapy and targeted radiotherapy.
What is being tested?
Researchers are testing CRB-601, an antibody targeting avb8 integrin in cancer cells, combined with anti-PD-1 immunotherapy and focused radiotherapy. They want to find the right dose of CRB-601 and see if it's safe and effective when used with these standard treatments.
What are the potential side effects?
Possible side effects include reactions to infusions such as fever or chills, fatigue, changes in blood tests indicating organ function issues, immune system responses that could affect healthy organs, and typical risks associated with radiation therapy.

Trial Design

9Treatment groups
Experimental Treatment
Group I: Part C - Low dose CRB-601, anti-PD(L)-1 with or without SBRTExperimental Treatment3 Interventions
Participants will received a low dose of CRB-601(defined in Part A \& B), standard of care dose of anti-PD(L)-1 therapy with or without 3 x 8gy doses of immune priming SBRT focused on a single lesion (as determined in Part B).
Group II: Part C - High dose CRB-601, anti-PD(L)-1 with or without SBRTExperimental Treatment3 Interventions
Participants will received a high dose of CRB-601(defined in Part A \& B), standard of care dose of anti-PD(L)-1 therapy with or without 3 x 8gy doses of immune priming SBRT focused on a single lesion (as determined in Part B).
Group III: Part B/Cohort 2 low dose CRB-601, anti-PD(L)-1 therapy and SBRTExperimental Treatment3 Interventions
Participants will received a low dose of CRB-601(defined in Part A), standard of care dose of anti-PD(L)-1 therapy and 3 x 8gy doses of immune priming SBRT focused on a single lesion.
Group IV: Part B/Cohort 2 high dose CRB-601, anti-PD(L)-1 therapy and SBRTExperimental Treatment3 Interventions
Participants will received a high dose of CRB-601(defined in Part A), standard of care dose of anti-PD(L)-1 therapy and 3 x 8gy doses of immune priming SBRT focused on a single lesion.
Group V: Part B/Cohort 1: Dose level (low) CRB-601 monotherapy in combination with anti-PD(L)-1Experimental Treatment2 Interventions
Dose (defined in Part A) of CRB-601 administered intravenously in combination with anti-PD(L)-1 therapy dosed as per label.
