Inclusion criteria

* Pre-menopausal female participants, 18 to 45 years of age, inclusive, at the time of signing the ICD who are at low risk of pregnancy * Participants who have a regular menstrual cycle (between 21 and 42 days in length). * No previous injection of depot MPA for 1 year prior to enrollment. * BMI of 17.5 to 30.5 kg/m2; and a total body weight \>50 kg (110 lb).

Exclusion criteria

* History of abnormal cervical cytology within the last 3 years that has not been adequately treated (at least 2 subsequent normal smears). However, ASCUS is permitted in this study. * Known or suspected malignancy of the breast or genital organs. * Known with metabolic bone disease. * Undiagnosed abnormal genital bleeding. * Known or suspected pregnancy; or nursing females. * History of febrile illness within 5 days prior to the first dose. * Participant with active thrombophlebitis or whose medical history suggests that they may be at increased risk for osteoporosis, thromboembolic disease or cerebral vascular disease. * Use of prescription or nonprescription drugs, vitamins, herbal preparations and dietary supplements capable of inducing hepatic metabolism (eg, barbiturates, rifampicin, carbamazepine or St John's Wort) or any medication known to be a * cytochrome P450 inhibitor within 30 days (or 5 half-lives of the substance, whichever is longer) of enrollment in the study * Use of hormonal contraception (including hormone releasing intrauterine device) within the last 3 months (and should have resumed regular menstruation). * Baseline 12-lead ECG that demonstrates clinically relevant abnormalities that may affect participant safety or interpretation of study results (eg, baseline QTc interval \>450 msec, complete LBBB, signs of an acute or indeterminate-age myocardial infarction, ST-T interval changes suggestive of myocardial ischemia, second- or third-degree AV block, or serious bradyarrhythmias or tachyarrhythmias). If the baseline uncorrected QT interval is \>450 msec, this interval should be rate-corrected using the Fridericia method and the resulting QTcF should be used for decision * making and reporting. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated 2 more times and the average of the 3 QTc or QRS values should be used to determine the participant's eligibility. Computer-interpreted ECGs should be overread by a physician experienced in reading ECGs before excluding participants.
