Details and patient eligibility

About

The current study is proposed to evaluate whether there is any clinically meaningful effect of hepatic impairment on the plasma Pharmacokinetic (PK) of PF-06882961

Enrollment: 24 patients

Sex: All

Ages: 18 to 70 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Male and female participants between the ages of 18 (or the minimum country-specific age of consent if >18) and 70 years, inclusive, at the screening visit:
• Participants who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, and other study procedures.
• Body mass index (BMI) of 17.5 to 38.0 kg/m2, inclusive; and a total body weight >50 kg (110 lb), at the screening visit; with a single repeat assessment of total body weight (and hence BMI), on a separate day permitted to assess eligibility, if needed.

Exclusion criteria

• Any condition possibly affecting drug absorption (eg, prior bariatric surgery, gastrectomy, ileal resection); NOTE: Participants who have undergone cholecystectomy and/or appendectomy are eligible for this study as long as the surgery occurred more than 6 months prior to Screening;
• At screening, participants with a positive result for human immunodeficiency virus (HIV) antibodies, as assessed by sponsor-identified central laboratory, with a single repeat permitted to assess eligibility, if needed;
• A positive COVID-19 test at screening;
• A diagnosis of type 2 diabetes mellitus (T2DM) that is documented by medical history;
• Personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN2), or participants with suspected MTC per the investigator's judgement;
• Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study;
• Use of prior/concomitant therapies
• Previous administration with an investigational drug within 30 days (or as determined by the local requirement) or 5 half-lives preceding the first dose of investigational product used in this study (whichever is longer);
• Participants with known prior participation (ie, randomized and received at least 1 dose of investigational product) in a study involving PF-06882961;
• Participants with ANY of the following abnormalities in clinical laboratory tests at Visit 1, as assessed by the study specific laboratory and confirmed by a single repeat test, if deemed necessary:

HbA1c ≥6.5%; FPG ≥126 mg/Dl; eGFR<60 mL/min/1.73m2;

• A positive urine drug test, for illicit drugs at screening, as assessed by sponsor-identified central laboratory. However, participants in Cohorts 2-4, only, who have been medically prescribed opiates/opioids or benzodiazepines and report the use of these drugs to the investigator at the Screening visit will be allowed to participate; NOTE: repeat urine drug testing is not permitted in this study;
• At screening or Day -1, a positive breath alcohol test, as assessed using kits provided by sponsor-identified central laboratory, with a single repeat on a separate day permitted to assess eligibility, if needed;
• Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing and until the follow-up contact; 13. History of sensitivity to heparin or heparin-induced thrombocytopenia, only if heparin is used to flush intravenous catheters used during serial blood collections;
• Unwilling or unable to comply with the criteria in the Lifestyle Considerations section of this protocol;
• Investigator site staff or Pfizer employees directly involved in the conduct of the study, site staff otherwise supervised by the investigator, and their respective family members.
