TRx0237 200 mg/day

Group Type EXPERIMENTAL

TRx0237 200 mg/day

Intervention Type DRUG

TRx0237 100 mg tablets will be administered twice daily.

Placebo

Group Type PLACEBO_COMPARATOR

Placebo

Intervention Type DRUG

Placebo tablets will be administered twice daily. The active placebo tablets include 4 mg of TRx0237 as a urinary and fecal colorant to maintain blinding; hence the placebo group will receive a total of 8 mg/day of TRx0237.
