Part 2: Single escalating dosesTR-01-XRR (1)Parallel group comparison, single p.o. dose escalation (3 dose levels) of 4 forms investigational study drug and placebo administered to two sequential cohorts. Dose Level 1 will be administered to the first cohort. Dose Levels 2 and 3 will be administered to a subsequent cohort. Dose levels in this cohort are separated by a 7-day washout period. Doses to be determined by review of data from Part 1.
