- NCT03765554
- Lead Sponsor
- Pfizer
- Brief Summary
PF-06700841 is a dual Tyrosine kinase 2 (TYK2) Janus kinase 1 (JAK1) inhibitor that is being developed for oral treatment of adult patients with Inflammatory Bowel Disease (IBD).This open-label study will evaluate the pharmacokinetics of PF-06700841 following single oral doses of immediate release (IR) and modified release (MR) tablets in healthy, adult participants under fasted conditions. This is an open label, single dose, randomized, 2 period, 2- sequence crossover study in a single cohort of approximately 8 (minimum 6) healthy participants.

Exclusion Criteria
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
- Any condition possibly affecting drug absorption (eg, gastrectomy).
- Have or have had clinically significant infections within the past 3 months prior to the first dose of investigational product (eg, those requiring hospitalization or parenteral antibiotics, or as judged by the Investigator), evidence of any infection within the past 7 days prior to the first dose of investigational product, herpes simplex within 12 weeks or history of disseminated herpes simplex infection, symptomatic herpes zoster or recurrent (>1 episode) or disseminated herpes zoster.
- History of human immunodeficiency virus (HIV), hepatitis B, or hepatitis C; positive testing for HIV, hepatitis B surface antigen (HepBsAg), hepatitis B core antibody (HepBcAb) or hepatitis C antibody (HCVAb). As an exception, a positive hepatitis B surface antibody (HepBsAb) finding as a result of participant vaccination is permissible.
- History of tuberculosis or active or latent or inadequately treated infection, positive QuantiFERON tuberculosis (TB) Gold test.
- 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).
- Female participants who are pregnant or wish to become pregnant; breastfeeding females.
- Males/Females of childbearing potential who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study and for at least 28 days after the last dose of investigational product.
- Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 56 days prior to dosing.
