Full description

Primary Objectives:

• To assess the comparative bioavailability of DFD-29 (Minocycline ER Capsules 40 mg) versus SOLODYN® (Minocycline ER Tablets 105 mg) following a single oral dose administration under fasting conditions in healthy adult human subjects.
• To assess the effect of food on DFD-29 (Minocycline ER Capsules 40 mg).

Secondary Objective:

• To evaluate and compare the safety and tolerability profiles of each study treatment.

Study Treatments:

Treatment-A: A single 40 mg dose of DFD-29 (Minocycline Hydrochloride) (1 × 40 mg Extended-Release capsule) administered following a 10-hour overnight fast Treatment-B: A single 40 mg dose of DFD-29 (Minocycline Hydrochloride) (1 × 40 mg Extended-Release capsule) administered following a 10-hour overnight fast and 30 minutes after the start of a high-fat, high calorie breakfast Treatment-C: A single 105 mg dose of SOLODYN® (Minocycline Hydrochloride) (1 × 105 mg Extended-Release tablet) administered following a 10-hour overnight fast.

Number of Subjects: Twenty-four (24) subjects will be included in the study Duration of the Study: Up to 58 days (including Screening) - Single dose treatment in each period.

PK Sample Collection: In each study period, 20 blood samples will be collected for PK assessments. The first blood sample will be collected prior to study treatment administration while the other blood samples will be collected at different timepoints up to 72 hours after study treatment administration.

Enrollment: 24 patients

Sex: All

Ages: 18 to 65 years old

(2), or (3) above as well as all the other inclusion criteria, Screening estradiol serum level must be equal to or below 150 pmol/L. In the case of hysterectomy, if FSH and estradiol do not meet the criteria, eligibility for study participation will be based on medical judgment. 5. If male, meets one of the following criteria:
