Study Endpoints

Primary Endpoints

Proportion of Participants with a Complete Response (CR) in the Delayed Phase of CINV
24 to 120 hours after first chemotherapy infusion

CR defined as no vomiting and no rescue medication

Number of Participants with One or More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration
Baseline through Day 119 (Part A) and Day 57 (Part B)

A summary of SAEs and other non-serious adverse events (AEs), regardless of causality, will be reported in the Reported Adverse Events module
