Official title
A Phase 1 Open-label Study to Investigate PF-08046876 in Adult Participants With Advanced Solid Tumors.
Overview
The purpose of the study is to explore the safety and effects of the study drug (PF-08046876) in people diagnosed with advanced cancer of the bladder, lung, head and neck, esophagus, or pancreas. PF-08046876 is an investigational anticancer therapy called an 'antibody drug conjugate' or 'ADC'. ADCs are anticancer drugs designed to stick to cancer cells and kill them. The study drug will be given to participants through a needle in a vein (intravenous infusion). This study includes multiple parts. In the first part of the study, there will be different groups of people receiving different doses of the study drug. The study may also test different schedules.
Interventions
- Drug PF-08046876
Intravenous administration
Primary outcome measures
- Incidence of Treatment Emergent Adverse Events (TEAEs) estimated during the Adverse Events (AE) evaluation [Time frame: Start of treatment up to 30 days after last dose or start of new anticancer therapy (whichever occurs first)]
- Part 1: Number of Participants With Dose-limiting Toxicities (DLTs): Monotherapy [Time frame: Baseline to end of DLT evaluation period]
- Part 1: Recommended Monotherapy Dose for Expansion [Time frame: Baseline to 30 days post last study drug administration]
- Part 2: Recommended Phase 2 Dose [Time frame: Baseline to 30 days post last study drug administration]
Secondary outcome measures (10)
- Objective Response Rate (ORR) [Time frame: Baseline until the date of the first documentation of disease progression, death, or start of new anticancer therapy (approximately 2 years)]
- Duration of Response (DOR) [Time frame: From the date of the first objective response to the date of disease progression or death (approximately 2 years)]
- Progression Free Survival (PFS) [Time frame: From Baseline to date of first disease progression or death (approximately 2 Years)]
- Overall Survival (OS) [Time frame: From baseline to up to 3 years]
- Pharmacokinetics (PK): Maximum Observed Serum Concentration (Cmax) [Time frame: Baseline to approximately 30 days after last dose of study drug]
- PK: Time to Reach Maximum Observed Plasma Concentration (Tmax) [Time frame: Baseline to approximately 30 days after last dose of study drug]
- PK: Area Under the Curve (AUC) from Time Zero to Last Quantifiable Concentration (AUClast) [Time frame: Baseline to approximately 30 days after last dose of study drug]
- Incidence of Anti-Drug Antibody (ADA) [Time frame: Baseline to approximately 30 days after last dose of study drug]
- Incidence of Neutralizing Antibodies (NAb) [Time frame: Baseline to approximately 30 days after last dose of study drug]
- Percent change of immune cells within tumors based on multiplex immunofluorescence [Time frame: Baseline through 4-7 weeks after first dose of study drug]
