Symbiotic-Lung-20: A Study to Learn About the Study Medicine Called PF-08634404 in Combination With Different Anticancer Agents in Advanced Cancers

Phase 2RecruitingNCT07227298

Pfizer162 enrolled

Overview

This study is being done to learn more about a new medicine called PF-08634404 and how it works when used with other cancer medicines in people who have advanced solid tumors. An advanced solid tumor is a type of cancer that has spread beyond its original location and cannot be removed by surgery or cured with standard treatments. To join in the study, participants must: * Be 18 years or older * Participants with advanced non-small cell lung cancer (NSCLC), a type of lung cancer that has spread The study will look at: * Whether PF-08634404 is safe to use with other cancer medicines. * What side effects may happen. A side effect is anything the medicine does to your body that is not part of treating your disease. * Whether the combination of PF-08634404 and other cancer medicines can help treat solid tumors. The study has different parts, each testing PF-08634404 with a different cancer medicine: * Part A will test PF-08634404 with a medicine called sigvotatug vedotin. * Part B of the study will look at how well the new medicine PF-08634404 works when used together with another medicine. Participants will receive the study medicines through an intravenous (IV) infusion (injected into the vein) at the study clinic. All treatments will take place at clinical trial sites, where trained medical staff will monitor participants during and after each visit.

Outcomes

Primary Outcomes

Number of Participants with Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)

AEs as characterized by type, frequency, severity (as graded by NCI CTCAE version 5.0), timing, seriousness, and relationship to study intervention.

Time frame: Through 90 days after the last study intervention; Up to approximately 5 years

Phase I: Number of participants with dose limiting toxicity (DLT)

Dose limiting toxicity based on dose limiting toxicity evaluable participants. The number of participants who experienced DLTs during the DLT observation period.

Time frame: Through 90 days after the last study intervention; Up to approximately 5 years

Phase 2: Confirmed Objective Response Rate (ORR) per RECIST v1.1 by investigator

ORR is defined as the proportion of participants with a Best Overall Response (BOR) of confirmed Complete Response (CR) or confirmed Partial Response (PR) per RECIST v1.1.

Time frame: Up to approximately 5 Years

Secondary Outcomes

Phase I: Confirmed ORR per RECIST v1.1 by investigator

ORR is defined as the proportion of participants with a Best Overall Response (BOR) of confirmed Complete Response (CR) or confirmed Partial Response (PR) per RECIST v1.1.

Time frame: Up to approximately 5 Years

Disease Control Rate (DCR) per RECIST v1.1 by investigator

DCR by investigator assessment is defined as the proportion of participants with CR or PR with confirmation, or Stable Disease (SD) by investigator assessment per RECIST version 1.1.

Time frame: Up to approximately 5 years

Duration of Response (DOR) per RECIST v1.1 by investigator

DOR is defined as the time from the first documentation of objective response (CR or PR that is subsequently confirmed) to the date of first documented disease progression per RECIST v1.1 or death due to any cause, whichever occurs first.

Time frame: Up to approximately 5 years

Progression Free Survival (PFS) per RECIST v1.1 by investigator

Progression-free survival is defined as the time from the date of randomization to the date of the first documentation of objective PD assessed by investigator per RECIST v1.1, or death due to any cause, whichever occurs first.

Time frame: Up to approximately 5 years

Number of Participants With Clinical Laboratory Abnormalities

Time frame: Through 90 days after the last study intervention; Up to approximately 5 years

Pharmacokinetics (PK): Serum concentration of PF-08634404 with anticancer agents

To characterize the pharmacokinetics (PK) of PF-08634404 with anticancer agents.

Time frame: Up to 37 days after the last dose of treatment

Incidence of Anti-Drug Antibody (ADA) against PF-08634404 with anticancer agents

To characterize the immunogenicity of PF-08634404 with anticancer agents.

Time frame: Up to 37 days after the last dose of treatment
