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

A PHASE 1, RANDOMIZED, DOUBLE-BLIND, SPONSOR-OPEN, PLACEBO-CONTROLLED STUDY TO ASSESS THE SAFETY, TOLERABILITY, AND PHARMACOKINETICS OF MULTIPLE ORAL DOSES OF PF-07081532 IN ADULT PARTICIPANTS WITH TYPE 2 DIABETES MELLITUS

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.

Inclusion Criteria:

• Females of non childbearing potential;
• Patients with T2DM, inadequately controlled with metformin;
• HbA1c ≥7.0% to ≤10.5% (for T2DM); HbA1c <6.5% (for non-diabetic obese, if enrolled)
• Total body weight >50 kg (110 lbs)
• BMI ≥24.5 to ≤45.5 kg/m2 (T2DM), BMI >30.5 to ≤45.5 kg/m2 (for non-diabetic obese)

Exclusion Criteria

• Positive COVID-19 test at screening or admission;

• Supine BP ≥160 mm Hg (systolic) or ≥100 mm Hg (diastolic);

• 12-lead ECG clinically relevant abnormalities that may affect participant safety or interpretation of study results;

• Participants with ANY of the following abnormalities in clinical laboratory tests: *AST or ALT level ≥1.5x ULN;

  • Total bilirubin level ≥1.5x ULN;
  • TSH> ULN;
  • Fasting C-peptide <0.8 ng/mL;
  • Serum calcitonin > ULN;
  • Amylase > ULN;
  • Lipase > ULN;
  • eGFR <60 mL/min/1.73m2 (per MDRD equation);
  • FPG >270 mg/dL

• History of alcohol abuse, binge drinking and/or any illicit drug use or dependence within 6 months of Screening;

• Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing;
