A Clinical Trial of PF-08046037 Alone or With Sasanlimab in Patients With Advanced or Metastatic Malignancies

Phase 1
Not yet recruiting
Conditions
Carcinoma, Non Small Cell Lung
Squamous Cell Carcinoma of the Head and Neck (SCCHN)
Carcinoma, Pancreatic Ductal
Malignant Melanoma
Interventions
Registration Number
NCT06974734
Lead Sponsor
Pfizer
Brief Summary

The purpose of this study is to learn about the safety and the effects of PF-08046037 alone or with sasanlimab for the treatment of certain advanced or metastatic malignancies.

This study is seeking participants who:

* have advanced or metastatic non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), melanoma, or pancreatic ductal adenocarcinoma (PDAC);

* are able to provide tumor tissue samples;

* have measurable disease. All participants will receive while at the clinic PF-08046037 alone as an intravenous (IV) infusion (given directly into a vein) or with sasanlimab as a subcutaneous (SQ) injection (given under the skin) once every 3 weeks.

Participants will continue to take the study drug(s) until their cancer is no longer responding or if the patient cannot safely take them. The study team will monitor how each participant is doing with the study treatment during regular visits at the study clinic.

Primary Outcome Measures
NameTimeMethod
Number of participants with DLTs by dose levelUp to 21 days
Number of participants with adverse events (AEs)Through 30-37 days after the last study treatment, up to approximately 2 years

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention

Number of participants with laboratory abnormalitiesThrough 30-37 days after the last study treatment, up to approximately 2 years
Number of dose modifications due to AEsThrough end of treatment up to approximately 2 years
Number of participants with dose-limiting toxicities (DLTs)Up to 21 days
Secondary Outcome Measures
NameTimeMethod
PK parameter - Trough concentration (Ctrough)Through 30-37 days after the last study treatment, up to approximately 2 years

PK endpoint

Number of participants with antidrug antibodies (ADAs)Through 30-37 days after the last study treatment, up to approximately 2 years
Objective response rate (ORR)Through end of study and up to approximately 2 years

The objective response rate (ORR) is defined as the percentage of participants with complete response (CR) or partial response (PR) which is subsequently confirmed as assessed according to Response Evaluation in Solid Tumors (RECIST) v1.1.

Best overall responseThrough end of study and up to approximately 2 years

The best overall response for a participant will be determined by the order of confirmed CR, confirmed PR, stable disease (SD), progressive disease (PD), not evaluable (NE) or not applicable (NA) per RECIST v1.1.

Duration of response (DOR)Through end of study and up to approximately 2 years

DOR is defined as the time from start of the first documentation of objective tumor response (CR or PR) to the first documentation of tumor progression per RECIST v1.1 or to death due to any cause

Progression-free survival (PFS)Through end of study and up to approximately 2 years

PFS is defined as the time from start of PF-08046037 to first documentation of disease progression (based on radiographic assessments per RECIST v1.1) or death due to any cause, whichever comes first

Overall survival (OS)Through end of study and up to approximately 2 years

OS is defined as the time from start of PF-08046037 to date of death due to any cause

Percent change of cells within tumors based on multiplex immunofluorescenceThrough end of study and up to approximately 2 years

This measure will assess the number of immune cells, PD-1, PD-L1, and TLR7 expression within the tumor microenvironment.

Pharmacokinetic (PK) parameter - Area under the concentration-time curve (AUC)Through 30-37 days after the last study treatment, up to approximately 2 years

PK endpoint

PK parameter - Maximum concentration (Cmax)Through 30-37 days after the last study treatment, up to approximately 2 years

PK endpoint

PK parameter - Time to maximum concentration (Tmax)Through 30-37 days after the last study treatment, up to approximately 2 years

PK endpoint

PK parameter - t1/2Through 30-37 days after the last study treatment, up to approximately 2 years

PK endpoint
