Reasons for withdrawal

Withdrawal data not reported

Baseline Characteristics

Twenty-five (25) subjects as explained above were enrolled and randomized into treatment groups, but withdrew from study prior to first dose. They did not came to baseline visit , receive study drug nor did they receive a post-randomization evaluation. The baseline was measured to 519 subjects who came to baseline visit , had assessment and took at least one dose of study medication . These are also the safety dataset.
