The subject must also agree to one of the following methods of contraception:

      • Complete abstinence from intercourse two weeks prior to administration of study drug, throughout the clinical trial, until the completion of follow-up procedures or for two weeks following discontinuation of the study medication in cases where subject discontinues the study prematurely. (Subjects utilizing this method must agree to use an alternate method of contraception if they should become sexually active and will be queried on whether they have been abstinent in the preceding 2 weeks when they present to the clinic for the Final Visit.) or,
