A Safety and Efficacy Study of Multiple Administration Regimens for Nivolumab Plus Ipilimumab in Subjects With Melanoma

This outcome describes the percentage of participants experiencing at least 1 AE in the MedDRA Anaphylactic Reaction broad scope SMQ. Such AEs include any acute systemic reaction characterized by a large list of terms, including (but not limited to) pruritus, urticaria, flushing, hypotension, respiratory distress, and vascular insufficiency. It also includes other signs and symptoms such as asthma, choking sensation, coughing, sneezing, and difficulty breathing due to laryngeal spasm and/or bronchospasm. Less frequent clinical presentations are also captured and include hyperventilation, sensation of foreign body, and ocular edema.

This outcome describes the percentage of participants experiencing at least 1 AE in the MedDRA Anaphylactic Reaction narrow scope SMQ. The narrow scope SMQ is composed of a large list of terms, including (but not limited to) anaphylactic shock and reaction, shock and shock symptoms, and circulatory collapse, among the others.

This outcome describes the percentage of participants experiencing at least 1 AE in the Hypersensitivity/Infusion select AEs category. The select AEs consist of a list of preferred terms defined by the Sponsor and represent AEs with a potential immune-mediated etiology. The following 5 MedDRA preferred terms are included in the hypersensitivity/infusion reaction select AE category: Anaphylactic Reaction, Anaphylactic Shock, Bronchospasm, Hypersensitivity, and Infusion Related Reaction

This outcome describes the percentage of participants who experienced at least 1 AE of Grade 3 or higher defined using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.0 criteria

This outcome describes the percentage of participants who experienced at least 1 Drug-related AE of Grade 3 or higher defined using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.0 criteria

The ORR is defined as the proportion of participants with a Best Overall Response (BOR) of Complete Response (CR) or Partial Response (PR). The BOR is defined as the best response designation, as determined by the investigator, recorded between the date of randomization and the date of objectively documented progression per RECIST 1.1 or the date of subsequent anti-cancer therapy, whichever occurs first.

PFS is defined as the time between the date of randomization and the first date of documented progression, as determined by the investigator, or death due to any cause, whichever occurs first.
