For the purpose of this study, the ULN for ALT is 45 U/L * Serum albumin ≥2 g/dL * Informed consent: All participants and/or their parents or legally authorized representatives must sign a written informed consent. Assent, when appropriate, will be obtained according to institutional guidelines. Participants must be willing to comply with all aspects of the protocol. Exclusion Criteria: * Pregnancy, breastfeeding, contraception: Females who are breastfeeding or pregnant at Screening or Baseline (as documented by a positive beta-human chorionic \[β-hCG\] or human chorionic gonadotropin \[hCG\] test with a minimum sensitivity of 25 International Units per Liter \[IU/L\] or equivalent units of β-hCG \[or hCG\]). A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the first dose of study drug. * Females of childbearing potential (all post pubertal females will be considered to be of childbearing potential unless they have early menopause \[amenorrheic for at least 12 consecutive months, in the appropriate age group, and without other known or suspected cause\] or have been sterilized surgically \[ie, bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month before dosing\]) who: * Do not agree to use a highly effective method of contraception for the entire study period and for 6 months after study drug discontinuation, ie: * Total abstinence (if it is their preferred and usual lifestyle); * An intrauterine device (IUD) or intrauterine system (IUS); * A contraceptive implant; * An oral contraceptive (must be on a stable dose of the same oral hormonal contraceptive product for at least 4 weeks before dosing with study drug and for the duration of the study and for 6 months after study drug discontinuation); or * Do not have a vasectomized partner with confirmed azoospermia. For sites outside of the European Union (EU), it is permissible that if a highly effective method of contraception is not appropriate or acceptable to the participant, or the participant has commenced/adjusted/changed oral hormonal contraceptive product/dose within 4 weeks prior to study drug administration, then the participant must agree to use a medically acceptable method of contraception, ie, double barrier methods of contraception such as condoms plus diaphragm or cervical/vault cap with spermicide. * Males who have not had a successful vasectomy (confirmed azoospermia) or if they and their female partners do not meet the criteria above (ie, not of childbearing potential or practicing highly effective contraception throughout the study period or for 3 months after study drug discontinuation).

- description
- Percentage of participants achieving a best objective response of partial response (PR) or complete response (CR) per RECIST 1.1, by up to 24 weeks after all participants have completed response assessment. Response assessment was determined by investigator. CR was defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must had reduction in the short axis to less than (\<) 10 millimeters (mm). PR was defined as at least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

- secondary Outcomes
- description
- PFS was defined as the time from the first dose date to the date of PD or date of death (whichever occurred first). PD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this included the baseline sum if that was the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions was also considered progression). Data for this secondary endpoint was collected and analyzed up to the primary completion date (PCD). As there was no further data collected, therefore data is reported till PCD only.
