- Conditions
- Healthy Female Volunteers
- Interventions
- Registration Number
- NCT04267250
- Lead Sponsor
- Pfizer
- Brief Summary
This Phase 1 study will assess the pharmacokinetic effect of multiple doses PF 06700841 (administered once a day) on a single dose of a combination oral contraceptive, in 18 healthy female participants who are not of childbearing potential.
- Detailed Description
This is a Phase 1, randomized, 2 way crossover, multiple-dose, open label study of the effect of multiple doses PF-06700841 on single dose combination oral contraceptive (OC) pharmacokinetics (PK) in healthy female participants aged 18-60.
The study consists of a screening phase (up to 28 days prior to Day 1); two treatment periods during which participants are resident in the Clinical Research Unit (CRU) and a final follow-up telephone contact, which will be conducted after 28-35 following administration of the last dose.
Participants will be randomized to 1 of 2 treatment sequences. A total of 18 healthy female participants (9 in each treatment sequence) will be enrolled in the study. Each treatment sequence will consist of 2 periods in a single fixed sequence. Participants will be screened within 28 days of the first dose of investigational product. Participants will report to the Clinical Research Unit (CRU) the day prior to Day 1 dosing in Period 1 for both treatment sequences, and will report to the CRU the day prior to Day 1 dosing in Period 2 for Treatment Sequence 2. In Treatment Sequence 1, participants will remain in the CRU for up to 21 days and 20 nights. There will be no washout period in Treatment Sequence 1. In Treatment Sequence 2, participants will remain in the CRU for up to 22 days and 20 nights. Participants in treatment sequence 2 will have an outpatient washout period of at least 10 days between Period 1 and Period 2. A single administration of OC in the form of 1 PORTIA or equivalent tablet will be administered in one of the two periods (reference treatment) and in the alternative treatment period, daily doses of 60 mg PF-06700841 will be administered for 13 days with a single dose of OC being administered on Day 10. PK (AUCinf, Cmax, AUClast, Tmax and t½) of OC will then be assessed at pre OC dose and over 96 hours, post OC dosing.
Safety assessments will be conducted at the CRU.

Group Intervention Description Sequence 2 PF-06700841 In sequence 2, period 1, participants will receive PF-06700841 PO for 13 days with a single dose of OC administered on the morning of day 10. After a wash-out period of at least 10 days, participants will continue into period 2 where they will receive an additional single dose of OC. Sequence 1 PF-06700841 In sequence 1, period 1, participants will be dosed with a single administration of oral contraceptive (OC). Participants will continue directly into period 2 where they will receive PF-06700841 PO for 13 days with a single dose of OC administered on the morning of day 10. Sequence 2 Ethinyl estradiol (EE) and levonorgestrel (LN) In sequence 2, period 1, participants will receive PF-06700841 PO for 13 days with a single dose of OC administered on the morning of day 10. After a wash-out period of at least 10 days, participants will continue into period 2 where they will receive an additional single dose of OC. Sequence 1 Ethinyl estradiol (EE) and levonorgestrel (LN) In sequence 1, period 1, participants will be dosed with a single administration of oral contraceptive (OC). Participants will continue directly into period 2 where they will receive PF-06700841 PO for 13 days with a single dose of OC administered on the morning of day 10.
