Participant Flow

Participants were enrolled at study sites in United States and New Zealand. The first participant was screened on 16 February 2015. The last study visit occurred on 26 January 2016.

171 participants were screened. Enrollment was sequential, with the longer treatment duration groups enrolled, treated, and evaluated for Sustained Virologic Response 4 Weeks After Discontinuation of Therapy (SVR4) prior to enrollment of the shorter treatment duration groups, which were not enrolled, at the discretion of the Sponsor.
