Study Description

Brief Summary:

This research study is studying an immunotherapy drug (pembrolizumab or KEYTRUDA) as a possible treatment for pediatric hepatocellular carcinoma or hepatocellular neoplasm not otherwise specified (HCN NOS).

Condition or disease	Intervention/treatment	Phase
Hepatocellular Carcinoma, Childhood; Fibrolamellar Carcinoma; Liver Cancer; Liver Cancer, Pediatric	Drug: Pembrolizumab	Phase 2

Detailed Description:

Patients who fulfill eligibility criteria will be entered into the trial to receive pembrolizumab or KEYTRUDA

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied. In the case of this trial, the investigators are studying whether pembrolizumab can treat pediatric hepatocellular carcinoma.

The FDA (the U.S. Food and Drug Administration) has not approved pembrolizumab for your specific disease but it has been approved for other uses in adults. Checkpoint inhibitors are in early-phase study in pediatric patients across diagnoses.

In this research study, the investigators plan to investigate whether pediatric patients with hepatocellular carcinoma experience stable disease or response to pembrolizumab. In addition, the investigators would like to explore different biological factors of the tumor and immune system that might help us predict whether pediatric patients with HCC may benefit from treatment with pembrolizumab.

• Disease Status: Participants must have measurable disease by RECIST criteria, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) measured at ≥20 mm with conventional technique or ≥10 mm with spiral CT scan, MRI, or calipers by clinical exam. See Section 10 for the evaluation of measurable disease.
• Performance Level: Karnofsky performance status ≥ 60% for patients ≥ 16 years of age or Lansky ≥ 60% for patients < 16 years of age.
• Prior Therapy: Patients must have fully recovered from the acute toxic effects of all prior anti-cancer therapy.
• Patients must not have received standard or targeted treatment regimens within 14 days of initiation of treatment with pembrolizumab.
• Patients must not have received prior radiotherapy within 7 days of initiation of treatment with pembrolizumab. Patients who have experienced radiation-induced adverse events must recover to a grade 1 prior to enrollment.

• Organ Function Requirements: Participants must have normal organ and marrow function as defined below:

  • Adequate Bone Marrow Function defined as:

    • Total bilirubin < 1.5 x institutional upper limit of normal (ULN)
    • AST(SGOT) ≤ 2.5 x ULN
    • ALT(SGPT) ≤ 2.5 x ULN
    • If liver function studies are more elevated than the thresholds above, and if if this elevation is felt secondary to tumor, patients may still be eligible for enrollment after discussion with the study PI.

  • Adequate Renal and Metabolic Function defined as:

If surgery was performed at the time of recurrence, this sample, in addition to a diagnostic sample should be submitted. If no re-operation was performed, archived tissue from diagnosis or the most recent procedure should be submitted (see section 9 for further details regarding tissue specifications).
