AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with advanced cancer of the bladder, lung, head and neck, esophagus, or pancreas, who have measurable disease and are fairly active in daily life.
- Age
- 18 years or older
- Sex
- All sexes can join
- Disease stage
- Advanced cancer of the bladder, lung, head and neck, esophagus, or pancreas, with measurable disease. Daily activity level (ECOG) 0-1. Part 3 needs advanced lung or bladder cancer.
- Earlier treatment
- Part 1: the cancer got worse or came back after standard treatments. Part 2: at most 2 earlier lines of drug treatment for advanced disease. Part 3: depends on the combination group. Side effects of earlier cancer treatment must be gone or mild (Grade 1).
- Biomarker or test result
- Participants must agree to give tumor tissue taken before treatment, if medically possible.
Main reasons for not taking part
- Earlier treatment with an antibody drug conjugate that has a camptothecin-class payload (e.g. sacituzumab govitecan, trastuzumab deruxtecan)
- Active loss of appetite, nausea or vomiting, or signs of a blocked bowel, as defined by the protocol
- Lung disease as defined by the protocol
- Part 3: contraindications to the combination medicines

- Original description
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.Read full original descriptionShow less
A Phase 1 Open-label Study to Investigate PF-08046876 in Adult Participants With Advanced Solid Tumors.
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. In the second part of the study, groups of people will receive the study drug in dosing regimens deemed to be safe in Part 1. In the third part of the study, people will receive the study drug together with other anti-cancer medicines.
Inclusion: 18 years of age or older; Advanced cancer of the bladder, lung, head and neck, esophagus, or pancreas; Measurable disease; ECOG Performance status 0-1; Part 1: progression or relapse following standard treatments; Part 2: maximum of 2 prior lines of systemic therapy in the advanced setting; Part 3: advanced cancer of the lung or bladder, prior treatment requirements vary by combination therapy group; Resolution of acute effects of prior anticancer therapy to baseline or Grade 1; Consent to submit required pre-treatment tumor tissue as medically feasible.
Exclusion: Received prior treatment with an antibody drug conjugate with a camptothecin-class payload (e.g. sacituzumab govitecan, trastuzumab deruxtecan ); Pulmonary disease meeting protocol exclusion; Active anorexia, nausea or vomiting, and/or signs of intestinal obstruction meeting protocol exclusion; Other unacceptable abnormalities as defined by protocol; Part 3: Meet contraindications of combination products per protocol and/or local labels.
