Study of Multiple Oral Doses of PF-07081532 in Adult Participants With Type 2 Diabetes Mellitus

Pfizer34 enrolled

Overview

This is a Phase 1, randomized, placebo-controlled, double-blind (investigator- and participant-blinded), sponsor-open study of PF-07081532. Study participants will receive the investigational product or placebo every day for 42 days. The purpose of the study is to evaluate the safety, tolerability and pharmacokinetics (PK) of multiple oral doses of PF-07081532 in participants with inadequately controlled type 2 diabetes mellitus, on metformin and optionally in non-diabetic participants with obesity.

Outcomes

Primary Outcomes

Number of Participants With Treatment-emergent Adverse Events (All Causalities)

An adverse event (AE) was any untoward medical occurrence in clinical study participant, temporally associated with the use of study drug, whether or not considered related to the study drug. A serious AE (SAE) was defined as one of the following: was fatal or life-threatening; resulted in persistent or significant disability/incapacity; constituted a congenital anomaly/birth defect; was medically significant; required inpatient hospitalization or prolongation of existing hospitalization. A severe AE was defined as severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling, limiting self-care activities of daily living. Treatment-emergent AE was defined as an AE with onset date occurring during the on-treatment period (starting after or on the first dose but before the last dose plus at least 28 days). AEs included all SAEs and non-SAEs.

Time frame: Baseline up to at least 28 days after last dose of study intervention (77 days)

Number of Participants With Treatment-emergent Adverse Events (Treatment Related)

A treatment related adverse event (AE) was any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study drug, considered related to the study drug (assessed by the investigator \[Yes/No\]). A serious AE (SAE) was defined as one of the following: was fatal or life-threatening; resulted in persistent or significant disability/incapacity; constituted a congenital anomaly/birth defect; was medically significant; required inpatient hospitalization or prolongation of existing hospitalization. A severe AE was defined as severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling, limiting self-care activities of daily living. Treatment-emergent AE was defined as an AE with onset date occurring during the on-treatment period (starting after or on the first dose but before the last dose plus at least 28 days). AEs included all SAEs and non-SAEs.
