PRIMARY outcome

Timeframe: First dose date up to last dose (up to 13.4 months)

Population: Participants in the Safety Analysis Set were analyzed.

Treatment-emergent graded laboratory abnormalities were defined as values that increase at least 2 toxicity grade from baseline at any time post baseline. The laboratory abnormalities were graded using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), where Grade 1: mild, Grade 2: moderate, Grade 3: severe, Grade 4: potentially life-threatening laboratory abnormality. The data is reported for shift of ≥ 2 grades from baseline in values for hematology and select liver biochemistry. Hematology includes parameters like RBCs, (erythrocytes), hemoglobin, hematocrit, platelets, WBC, WBC differentials (absolute and percentage) including basophils, neutrophils, lymphocytes, eosinophils, and monocytes, etc. Biochemistry included select liver function tests like blood bilirubin, gamma-glutamyl transferase (GGT), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase. Percentages were rounded-off.

SECONDARY outcome

Timeframe: Baseline, Month 6

Population: The Moderate to Severe Pruritus NRS Analysis Set included participants in the Intent-to-treat Analysis Set who had a baseline NRS value ≥ 4. Participants with available data were analyzed.

Pruritus NRS is used to rate the intensity of the itching experienced by the participants in the past 24 hours from no itching to worst possible itching by selecting a number from 0 to 10 on Itch Scale. Zero means no itching and 10 means worst imaginable itching.
