Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Use of nivolumab and entinostat in combination for the treatment of children and adolescents with refractory/relapsed/progressive high risk solid tumours or CNS tumours with no standard of care treatment available.

The study commenced in Phase I with two patient groups (12-21 years and 6-11 years) and evaluated the safety profile and recommended Phase II dose (RP2D) of the combination treatment.

The trial started with a dose escalation Phase I in the older cohort. Patients entering the trial on the RP2D in Phase I of the study can seamlessly enter Phase II. All groups in Phase II receive the RP2D. Dose de-escalation may occur intra-individually in response to toxicity in both phases of the trial.

The trial is currently in Phase II for both the older cohort (12-21 years) and younger cohort (2-11 years). The trial is evaluating the safety and anti-tumour activity of the combination treatment in patients who have the following biomarkers in their tumour:
(i) high mutational load, or
(ii) focal MYC(N) amplification or ATRT-MYC subgroup, or
(iii) high tumour-infiltrating lymphocytes (TILs) or tertiary lymphoid structures (TLS)

Nivolumab is given at 3mg/kg body weight every 2 weeks, as a 30 minute intravenous (IV) infusion. Entinostat is given orally as a tablet or liquid suspension. The recommended dose of entinostat for Phase II of the trial is 2mg/m2 for the younger cohort and 4mg/m2 for the older cohort.

There is one priming week (one dose of entinostat on day 1) followed by cycles of combination treatment. 12 cycles of treatment is planned and each cycle is 4 weeks. Entinostat is taken on days 1, 8, 15, 22, with IV administration of nivolumab on day 1 and 15.

Summary
Brief summary
The aim of this clinical trial is to find out whether combination treatment with nivolumab and entinostat is safe and effective for children and adolescents with high-risk cancer.

Who is it for?

You may be eligible for this study if you are aged 2-21 years old and have been diagnosed with a relapsed or refractory high-risk cancer or high grade glioma with a repair defect of the genetic material.

Study details:

If you are eligible to participate, you will always receive the drugs nivolumab and entinostat in combination. There will be no placebo or control group with any other medication.

Before treatment starts, there will be a screening phase. Molecular profiling (DNA sequencing of the tumour) will be performed and the molecular results will indicate if you are eligible for this study. You will be allocated to one of three biomarker groups and continue with screening. Routine tests will also be performed to confirm whether you are eligible for this study, and if you can start treatment. These include medical history, physical exam, CT or MRI scans of the tumour, ECG, blood tests and urine tests.

During study treatment:

Entinostat is a tablet or liquid taken once a week. Nivolumab is given at the hospital every two weeks, as an intravenous drip over 30 minutes. Routine tests will be performed during treatment to monitor your health. These include medical history, physical exam, CT or MRI scans of the tumour, ECG, blood tests and urine tests. Additional blood samples are collected for this study to measure the levels of drugs and examine how they are working the body.

You will be in this study for up to 4 years. This includes the screening phase, study treatment (12 cycles for about 1 year), follow-up visits (every 4 weeks up to 100 days) and long term observation (every 3 months until the study closes).
