Study Endpoints
Primary Endpoints
Number of Participants With Nausea During the First 2 Weeks of Treatment
Baseline up to Week 2

Nausea by spontaneous reports to the investigators was counted if it was reported during first 2 weeks of treatment, and it was not seen before the first dose of treatment, or if it was seen before the first dose and the symptoms got worse. If multiple incidences occurred on the same participant during the 2 weeks, only 1 incidence was counted.

Discontinuation Emergent Signs and Symptoms (DESS) Total Score at the End of First Week of Tapering
Week 17

DESS: a clinician-administered 43-item assessment that evaluates discontinuation-emergent symptoms resulting from the withdrawal from test article. The DESS total score is the sum of the number of "new symptoms" and "old (but worse) symptoms" (1) and 0 for "old and unchanged symptom", "absent", or "old symptom but improved" for a total possible range of 0 to 43. A higher score indicates more symptoms.

DESS Total Score at End of Second Week of Tapering
Week 18

DESS: a clinician-administered 43-item assessment that evaluates discontinuation-emergent symptoms resulting from the withdrawal from test article. The DESS total score is the sum of the number of "new symptoms" and "old (but worse) symptoms" (1) and 0 for "old and unchanged symptom", "absent", or "old symptom but improved" for a total possible range of 0 to 43. A higher score indicates more symptoms.

DESS Total Score at 1 Week After the End of Tapering
Week 19

DESS: a clinician-administered 43-item assessment that evaluates discontinuation-emergent symptoms resulting from the withdrawal from test article. The DESS total score is the sum of the number of "new symptoms" and "old (but worse) symptoms" (1) and 0 for "old and unchanged symptom", "absent", or "old symptom but improved" for a total possible range of 0 to 43. A higher score indicates more symptoms.
