Ages Eligible for Study:   18 Years to 55 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Subjects must have completed the Termination visit of MS-LAQ-301 (completion of all Termination visit activities) according to the MS-LAQ-301 protocol.
  2. Women of child-bearing potential must practice an acceptable method of birth control [acceptable methods of birth control in this open label extension phase include: surgical sterilization, intrauterine devices, oral contraceptive, contraceptive patch (or hormone-releasing vaginal ring), long-acting injectable contraceptive, partner's vasectomy or double-barrier method (condom or diaphragm with spermicide)] during the study and up to 30 days after the last dose of the study drug..
  3. Subjects must be willing and able to comply with the protocol requirements for the duration of the study.
  4. Subjects must be able to comprehend, sign and date a written informed consent prior to entering the MS-LAQ-301E study.

Exclusion Criteria:

  2. Pregnancy [according to urine dipstick β-HCG test performed at Baseline (Month 0E) visit] or breastfeeding.
  3. Subjects with clinically significant or unstable medical or surgical condition detected or worsened during the MS-LAQ-301 study, which preclude safe participation and completion of the MS-LAQ-301E study. Acute exacerbation of MS will not exclude participation in the MS-LAQ-301E study.
  4. Use of inhibitors of CYP3A4 within 2 weeks prior to baseline visit (V0E, Month 0E).
