Part 1: Number of Participants With Any Adverse Events (AEs) and Serious Adverse Events (SAEs)
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the study treatment. SAE is defined as any untoward medical occurrence that, at any dose resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent disability/incapacity, or is a congenital anomaly/birth defect, other situations which involved medical or scientific judgment or is associated with liver injury and impaired liver function. SAEs are subset of AEs. AEs were coded using the Medical Dictionary for Regulatory Activities (MedDRA dictionary).
Measured: Up to 29 weeks
Part 1: Number of Participants With Dose Limiting Toxicities (DLTs)
Criteria for dose-limiting toxicity (DLT) included hematologic indicators such as febrile neutropenia as defined by CTCAE v5; Grade 4 neutropenia of >7 days in duration; Grade 4 anemia and Grade 3-4 thrombocytopenia with bleeding.

The number of participants with decreases to low from baseline, changes to normal or no changes from baseline, and increases to high values have been presented. Baseline was defined as the most recent, non-missing value prior to or on the first study treatment dose date.
Measured: Baseline (Day 1) and up to 29 weeks
Part 1: Number of Participants With Worst-case Change Post-baseline in Clinical Chemistry Parameters
Blood samples were collected for evaluation of clinical chemistry parameters. The summaries of worst-case change from Baseline with respect to normal range have been presented for only those laboratory tests that are gradable by Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The number of participants with decreases to low from baseline, changes to normal or no changes from baseline, and increases to high values have been presented. Baseline was defined as the most recent, non-missing value prior to or on the first study treatment dose date.
Measured: Baseline (Day 1) and up to 29 weeks
Part 1: Number of Participants With Worst Case Change Post-baseline in Urinalysis Parameters
Urine samples were collected for evaluation of urinalysis parameters using dipstick method. The dipstick test gave results in a semi-quantitative manner. Baseline was defined as the most recent, non-missing value prior to or on the first study treatment dose date. The summaries of worst-case change from Baseline with respect to normal range have been presented for only those laboratory tests that are gradable by CTCAE v5.0.

Urine samples were collected from participants to assess urine pH levels. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 - 6.0). Baseline was defined as the most recent, non-missing value prior to or on the first study treatment dose date. Changes from baseline in urine pH were reported.
Measured: Baseline (Day 1), week 4, week 7, week 10, week 13 and week 29 (Treatment Discontinuation)
Part 1: Change From Baseline in Specific Gravity of Urine
Urine samples were collected from participants to analyze urine specific gravity. Baseline was defined as the most recent, non-missing value prior to or on the first study treatment dose date. Changes from baseline in specific gravity of urine were reported.

Urine samples were collected from participants to assess urine pH levels. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 - 6.0). Baseline was defined as the most recent, non-missing value prior to or on the first study treatment dose date. Changes from baseline in urine pH were reported.
Part 1: Change From Baseline in Specific Gravity of Urine
Time frame: Baseline (Day 1), week 4, week 7, week 10, week 13 and week 29 (Treatment Discontinuation)
Urine samples were collected from participants to analyze urine specific gravity. Baseline was defined as the most recent, non-missing value prior to or on the first study treatment dose date. Changes from baseline in specific gravity of urine were reported.
Part 1: Number of Participants With AE Leading to Dose Modifications
Time frame: Up to 29 weeks
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the study treatment. The number of participants who experienced AE leading to dose modifications were evaluated.
