Oral Bio-equivalence Study

Title of Study: An Open-Label, Balanced, Randomized, 2-Treatment, 2-Sequence, 2-Period, Single Dose, Crossover Oral Bioequivalence Study of Two Formulations of Fingolimod Capsules (3 x 0.5 mg) in Healthy Adult Human Subjects Under Fasting Conditions.

Objective: The objective of this study is to compare the oral bioavailability and characterize the pharmacokinetic profile of the test formulation relative to that of reference formulation in healthy, adult, human subjects under fasting conditions and to assess the bioequivalence.


Eligibility Criteria:
Inclusion Criteria:

Volunteers meeting all of the following criteria will be considered for enrollment in the study:

1. Availability for the entire study period 2. Motivated volunteer and absence of intellectual problems likely to limit the validity of consent to participate in the study or the compliance with protocol requirements; ability to cooperate adequately; ability to understand and observe the instructions of the physician or designee 3. Male or female volunteer 4. A female volunteer must meet one of the following criteria:

1. Physiological postmenopausal status, defined as the following:

   1. no menses for at least one year (absence of menses should not be due to lactational amenorrhea); and
   2. FSH levels ≥ 40 mIU/mL at screening; or
2. Surgical postmenopausal status, defined as the following:

   1. bilateral oophorectomy; and
   2. absence of menses for at least 3 months; and
   3. FSH levels ≥ 40 mIU/mL at screening; or
3. Hysterectomy with FSH levels ≥ 40 mIU/mL at screening If the postmenopausal volunteer has an FSH of \< 40 mIU/mL, but meets the above criteria in either (1), (2) or (3) and all the other inclusion criteria in section 5.2, the volunteer may be included in the study if the estradiol serum level measured at screening is equal to or below 150 pmol/L. In the case of hysterectomy, if FSH and estradiol do not meet the criteria, inclusion of the volunteer will be based on medical judgment. 5. Volunteer aged of at least 18 years but not older than 45 years 6. Volunteer with a BMI greater than or equal to 18.50 kg/m2 and below 30.00 kg/m2 7.

Clinical laboratory values within the laboratory's stated normal range; if not within this range, they must be without any clinical significance 10. Have no clinically significant diseases captured in the medical history or evidence of clinically significant findings on physical examination and/or clinical laboratory evaluations (hematology, general biochemistry, ECG and urinalysis) 11. Willingness to adhere to the protocol requirements as evidenced by the informed consent form (ICF) duly read, signed and dated by the volunteer 12. Volunteer agrees not to participate in another clinical study for up to 10 weeks following the last drug administration The ICF must be signed by all volunteers prior to their participation in the study.
