This is a randomized, placebo-controlled, double-blind (investigator- and participant-blinded), sponsor-open, dose-escalating study of PF-07081532 in patients with Type 2 diabetes on metformin (Parts A and C). The study may also enroll non-diabetic participants with obesity (Part B). Study participants will receive an investigational product or placebo every day for up to 28 days (Part A) or up to 42 days (Part B, optional; Part C, optional). The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of multiple oral doses of PF-07081532 in participants with inadequately controlled T2DM on metformin and optionally in non-diabetic obese participants.

Number of Participants With Treatment Emergent Treatment-Related Adverse Events
An adverse event (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. An serious adverse event (SAE) was defined as an AE: 1. resulting in death, 2. was life-threatening, 3. required inpatient hospitalization or prolongation of existing hospitalization, 4. resulted in persistent disability, 5. was a congenital anomaly/birth defect, or considered to be an important medical event. Treatment-related AE was any untoward medical occurrence attributed to study intervention in a participant who received study intervention. Treatment-emergent are events between first dose of study intervention and up to 28-35 days after last dose that were absent before treatment or that worsened relative to pretreatment state.
Time frame: From the first dose up to 28-35 days after last administration of study intervention (that is a maximum of 63 days from first dose for Part A and a maximum of 77 days from first dose for Part B and Part C)
Number of Participants With Laboratory Abnormalities
Participants with laboratory abnormalities with ≥2 occurrences (without regard to baseline abnormality) that met pre-specified criteria were High-density lipoprotein (HDL) Cholesterol \<0.8✕ lower limit of normal (LLN); Bicarbonate \<0.9✕LLN; Calcitonin\>1.0✕upper limit of normal (ULN); Triglycerides \>1.3✕ULN; Aspartate Aminotransferase \>3.0✕ULN; Low-density lipoprotein (LDL) Cholesterol \>1.2✕ULN; Urine Glucose ≥1; Urine Ketones ≥1; Urine Leukocyte Esterase ≥1; Urine Leukocytes ≥20; Urine Hyaline Casts \>1; Urine Hemoglobin ≥1; and Urine Nitrite ≥1.
Time frame: From Baseline to 7-14 days following last dose administration (that is a maximum of 42 days from baseline for Part A and a maximum of 56 days from baseline for Part B and Part C)
Number of Participants With Vital Signs Abnormalities
Vital signs (pulse rate, systolic and diastolic blood pressure) were obtained with participant in the supine position. The pre-specified categorical analysis criteria in vital signs, were supine systolic blood pressure \< 90 millimeters of mercury (mmHg), supine systolic blood pressure increase/decrease from baseline ≥ 30mmHg; supine diastolic blood pressure \<50 mmHg, supine diastolic blood pressure increase/decrease from baseline ≥ 20mmHg; pulse rate \<40 beats per minute (bpm) or \>120 bpm.
Time frame: From Baseline to 7-14 days following last dose administration (that is a maximum of 42 days from baseline for Part A and a maximum of 56 days from baseline for Part B and Part C)
Number of Participants With Abnormal Electrocardiogram (ECG)
The pre-specified categorical analysis criteria in ECG, were PR interval: value ≥ 300 milliseconds (msec), percentage change ≥ 25/50%; QRS duration: value ≥140 msec, percentage change ≥ 50%; QTcF interval: 450 \< value ≤ 480 msec, 480 \< value ≤ 500 msec, value \>500 msec, and 30\<change ≤ 60 msec, change \>60 msec.
Time frame: From Baseline to 7-14 days following last dose administration (that is a maximum of 42 days from baseline for Part A and a maximum of 56 days from baseline for Part B and Part C)
