In subjects who are sexually active, willingness to abstain from sexual intercourse or employ a barrier or medical method of contraception during the study drug administration and 6 week follow up period. 4. Willingness and ability to comply with scheduled visits, PTC124 administration plan, study procedures, laboratory tests, and study restrictions. Are the trial subjects under 18? yes Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: Patients meeting any of the following conditions will not be eligible for enrollment into the study: 1. Known hypersensitivity to any of the ingredients or excipients of the study drug (Litesse® UltraTM [refined polydextrose], polyethylene glycol 3350, Lutrol® micro F127 [poloxamer 407], mannitol 25C, crospovidone XL10, hydroxyethyl cellulose, vanilla, Cab O Sil® M5P [colloidal silica], magnesium stearate). 2. Ongoing participation in any other therapeutic clinical trial. 3. Prior or ongoing medical condition (eg, concomitant illness, psychiatric condition, behavioral disorder, alcoholism, drug abuse), medical history, physical findings, ECG findings, or laboratory abnormality that, in the investigator’s opinion, could adversely affect the safety of the subject, makes it unlikely that the course of treatment or follow up would be completed, or could impair the assessment of study results.
