- Brief Summary
The purpose of this study is to learn about the effects of a new study medicine called PF-08046032, when taken alone and when taken with another medicine called sasanlimab, for the treatment of advanced cancers. The effects are studied in adult participants with certain types of lymphomas or solid tumors that are advanced or metastatic (spread to other parts of the body).
The study has three parts:
* Part A will test PF-08046032 alone at increasing dose levels in participants with certain lymphomas (cancer that begins in cells of the immune system) and in participants with certain solid tumors whose disease has worsened on or after standard treatments.
* Part B will test PF-08046032 (at selected doses) and sasanlimab in participants with certain solid tumors, including those whose disease has worsened on or after standard treatments as well as participants before receiving standard treatments.
* Part C will further test the combination of PF-08046032 and sasanlimab in participants with specific types of solid tumors based on the results from Part A and Part B of the study.
All participants will receive the study drug PF-08046032. Only participants in Part B and Part C of the study will also receive sasanlimab. PF-08046032 will be given as an intravenous (IV) infusion, which means it will be injected directly into a vein. Sasanlimab will be given as a subcutaneous injection, which means it will be injected under the skin.

- Primary Outcome Measures
Name Time Method Part A and Part B: Number of participants with dose limiting toxicities (DLTs) in dose escalation Day of first dose (Day 1) through the end of DLT Observation period (up to 28 days) DLT (any of the prespecified AEs that are attributable to study treatment(s), excluding toxicities clearly due to underlying disease or extraneous causes) rate estimated based on data from DLT-evaluable participants during the DLT evaluation period
All Parts: Number of participants with adverse events (AEs) From first dose (Day 1) through up to 30 days after last dose of PF-08046032 or up to 90 days after last dose of sasanlimab AEs as characterized by type, frequency, severity (CTCAE v5), seriousness, and relationship to study drug(s)
All Parts: Frequency of dose modifications due to AEs From first dose (Day 1) through up to 30 days after last dose of PF-08046032 or up to 90 days after last dose of sasanlimab Dose modifications such as dose delay, treatment interruptions, dose reducations, and treatment discontinuations due to AEs
All Parts: Number of participants with clinically significant lab abnormalities From first dose (Day 1) through up to 30 days after last dose of PF-08046032 or up to 90 days after last dose of sasanlimab Lab abnormalities characterized by type, frequency, and severity (CTCAE v5)
- Secondary Outcome Measures
Name Time Method Objective Response Rate (ORR) in Participants with Solid Tumors Response assessments at baseline and every 8 to 12 weeks through time of disease progression, death, unacceptable toxicity, or through study completion (Approximately 3 Years) Based on investigator assessment, and defined as the proportion of participants who achieved best overall response of CR or PR according to RECIST 1.1
Duration of Response (DoR) in Participants with Solid Tumors Time from first documented objective response to the date of first documented radiographic progression or death (Approximately 3 Years) Based on investigator assessment for participants with a confirmed objective response (CR or PR) only.
Progression-free survival (PFS) in Participants with Solid Tumors Time from first dose (Day 1) to the date of first documented radiographic progression or death (Approximately 3 Years) Based on investigator assessment for tumor response/progression according to RECIST v1.1
Objective Response Rate (ORR) in participants with lymphomas based on Lugano Criteria Response assessments at baseline and every 8 to 12 weeks through time of disease progression, death, unacceptable toxicity, or through study completion (Approximately 3 Years) Based on investigator assessment, and defined as the proportion of participants who achieved best overall response according to Lugano Criteria
Progression-free survival (PFS) in participants with lymphomas based on Lugano Criteria Time from first dose (Day 1) to the date of first documented radiographic progression or death (Approximately 3 Years) Based on investigator assessment for tumor response/progression according to Lugano Response Classification Criteria
