Who can take part
You may be able to join if
- Participants must meet the following age criteria at the time of signing the ICF: • Part 1: Cohort 1a: 12 years to <18 years; Cohort 1b: 6 years to <12 years; Cohort 1c: 2 to <6 years; Cohort 1d: 0 to <2 years. • Part 2: Cohort A: 6 to <21 years; Cohort B: 6 to <21 years; Cohort C: Age to be decided.
- Type of participants and disease characteristics: • Part 1: Participants with advanced or metastatic solid tumors who have had disease progression after treatment with available therapies that are known to confer clinical benefit and who have limited available treatment options as determined by the investigator. Additionally, exposure to prior immunotherapy or experimental therapies is acceptable: Melanoma; Hodgkin Lymphoma; High and Low Grade Glioma: including GBM, DIPG, and ependymoma; Osteosarcoma; Hepatic tumors (including Hepatoblastoma, HCC, and Fibrolamellar carcinoma); Rhabdomyosarcoma. • Part 2: Cohort A: Melanoma patients who have not received prior systemic therapy: − Participants with BRAF mutations who are eligible for a BRAF-targeted therapy are eligible if they qualify for immunotherapy. − Participants with locally treated and controlled metastatic CNS lesions without leptomeningeal spread are eligible. Cohort B: Hodgkin lymphoma - Relapsed/refractory Hodgkin lymphoma that has failed at least 2 prior lines of systemic therapy). Cohort C: Indication/s to be decided based on Part 1 results.
- Participant has measurable disease, that is, presenting with at least 1 measurable lesion as determined by the local site Investigator/radiology assessment. Target lesions situated in a previously irradiated area are considered measurable if disease progression has been demonstrated in such lesions and if there are other target lesions. If there is only 1 target lesion that was previously irradiated, the participant is not eligible. Eligible HL participants must have at least one FDG-avid lesion, preferably with higher intensity than normal liver.
- Participants must have performance status ≥60% on the Karnofsky scale for participants >16 years of age and ≥60% on the Lansky scale for participants ≤16 years of age.
- Adequate organ function as demonstrated by a complete blood count at screening obtained without transfusion (platelets or RBC) or receipt of CSF, G-CSF, GMCSF or rEPO within 2 weeks prior to screening labs, with the following results: • ANC ≥1,000/μL; • platelets ≥75,000/μL; • hemoglobin ≥9 g/dL or ≥5.6 mmol/L; • glomerular filtration rate ≥50 mL/min; • AST <2.5 × ULN; • ALT <2.5 × ULN; • bilirubin ≤1.5 × ULN; • international normalized ratio or PT ≤1.5×ULN unless the participant is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants; • activated PTT ≤1.5×ULN unless the participant is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants.
- Adolescent participants who have entered puberty must consent (be willing) to use of contraceptive measures, or refrain from sexual intercourse, if in line with their usual practice, as well as sperm/egg donation for the duration of treatment as described below: Contraceptive use by male and female participants should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. A female participant is eligible to participate if she is not pregnant or breastfeeding, and one of the following conditions applies: Is a woman of non-childbearing potential (WONCBP) OR is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of <1% per year), during the study intervention period and for at least 150 days after the last dose of study intervention. A WOCBP must a negative highly sensitive pregnancy test (urine or serum as required by local regulations) within 24 hours before the first dose of study intervention. If a urine test cannot be confirmed as negative (e.g., an ambiguous result), a serum pregnancy test is required.
You likely can't join if
- Participant has uncontrolled CNS involvement by any tumor pathology (this would include leptomeningeal disease, and/or any new or progressive symptoms).
- Has current active pneumonitis or any history of pneumonitis requiring steroids or immunomodulatory treatment within 90 days of planned enrollment or any history of drug-induced pneumonitis.

Participants with prior history of autoimmune disease must be discussed with the medical monitor. Replacement therapy is not considered a form of systemic therapy (e.g., thyroid hormone for autoimmune thyroiditis or insulin is not exclusionary).
- Has ongoing adverse reaction(s) from prior therapy that has(have) not recovered to ≤Grade 1 or to the baseline status preceding prior therapy, excluding [e.g., alopecia, hearing loss, vitiligo, endocrinopathy managed with replacement therapy, and Grade 2 neuropathy], or that the investigator, with the agreement of the sponsor, considers to be not clinically relevant for the tolerability of study intervention in the current clinical study.
- Has any active renal condition (e.g., infection, requirement for dialysis, or any other significant renal condition ( that could affect the participant’s safety).
- Has any serious and/or unstable medical or psychiatric disorder or other condition(s) (including laboratory assessment abnormalities) that could interfere with the participant’s safety, obtainment of informed consent, or compliance to the study procedures.
