Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Histological or cytological diagnosis of advanced, unresectable, and/or metastatic or relapsed/refractory solid tumor
Participants with 'cold' solid tumors where anti-PD-(L)1 therapy is not an established treatment
Must not have
Brain metastasis or primary brain tumor requiring immediate local intervention
Treatment with any systemic anticancer therapy within 4 weeks or 5 half-lives (whichever is shorter) prior to planned first dose
Timeline
Screening 3 weeks
Treatment Varies
Follow Up baseline and every 8 to 12 weeks through time of confirmed disease progression, death, unacceptable toxicity, or through study completion, approximately 2 years
Awards & highlights
Summary
This trial aims to study the safety and effects of a new drug, PF-07329640, for treating solid tumors such as lung cancer, colorectal cancer, urothelial cancer, and
Who is the study for?
Participants with advanced or metastatic solid tumors, including NSCLC, CRC, UC, and melanoma. They will receive PF-07329640 via IV infusion weekly for 28-day cycles and may also get bevacizumab every two weeks or sasanlimab every four weeks.
What is being tested?
The trial is testing the safety and effects of PF-07329640 alone or combined with bevacizumab or sasanlimab on various cancers. It aims to determine the optimal dosing while monitoring participants' responses over up to four years.
What are the potential side effects?
Potential side effects include reactions related to IV infusions, possible immune system impacts due to cancer medications which could lead to inflammation in different body parts, fatigue, skin reactions at injection sites, and increased risk of infections.
