Ribociclib and Everolimus in Treating Children With Recurrent or Refractory Malignant Brain Tumors

Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. Found by searching ClinicalTrials.gov for this cancer type, restricted to studies that have posted results to the registry. No FDA notice, FDA label or NCI summary held by this site cites this study. Because the search asked for posted results, studies without posted results were never looked for, so their absence from this page means nothing.

exploratory · POSTED

Ribociclib plasma concentration-time data obtained from patients who received Phase I defined treatment will be modeled using compartmental approaches to estimate the AUC (hr\*μM) for each dose level on days 1 and 17 of course 1. Patients who were enrolled in the Surgical stratum but subsequently received Phase I defined treatment with PK data available will also be included in the analysis population. 5 patients from surgical stratum received dose level 1 treatment.

Patients with blood samples collected for pharmacokinetic studies on days 1 and 17 of course 1 were included. Surgical patients who received Phase I treatment with samples collected were also included in Dose Level 1. There are total 17 patients received dose level 1 treatment and 3 patients received dose level 2 treatment.

Everolimus plasma concentration-time data obtained from patients who received Phase I defined treatment will be modeled using compartmental approaches to estimate the AUC (hr\*nM) for each dose level on day 17 of course 1 and day 1 of course 2. Patients who were enrolled in the Surgical stratum but subsequently received Phase I defined treatment with PK data available will also be included in the analysis population. 5 patients from surgical stratum received dose level 1 treatment.

Patients with blood samples collected for pharmacokinetic studies on day 17 of course 1 and day 1 of course 2 were included. Surgical patients who received Phase I treatment with samples collected were also included in Dose Level 1. There are total 17 patients received dose level 1 treatment and 3 patients received dose level 2 treatment. Analysis population only includes treated patients with corresponding PK data available.

primary · POSTED

Defined as the highest dose level at which six patients have been treated with at most one patient experiencing a dose limiting toxicity (DLT) and the next higher dose level has been determined to be too toxic. Will be estimated using a Rolling-6 phase I design. Only patients who are evaluable for DLT will be consider for estimating of Maximum Tolerated Dose. Patient who were enrolled under Surgical cohort but received sufficient study defined treatment would also be evaluable for DLT.

Patients who were evaluable for dose finding assessment were used to determine the MTD. Evaluable patients are those who were eligible, started treatment and either experienced a dose limiting toxicity during course 1 or received adequate amount of treatment and were followed adequately to be assessed for safety during course 1. Evaluable patients could be from either Phase I stratum or from Surgical stratum as long as they received sufficient protocol defined Phase I treatment.

primary · POSTED

Average tumor Ribociclib concentrations will be compared to plasma concentrations. The mean tumor-to-plasma ratio of Ribociclib at the time of surgery will be described.

Patients who were enrolled on surgical study and with tumor and matching plasma samples available.

→

secondary · POSTED

Number of patients with sustained objective responses will be reported by stratum and dose. Objective response refers to at least 50% reduction in 2 dimensional measurements of the tumor. In order to count towards this objective, any response needs to be sustained for at least 8 weeks.

Patients who received Phase I treatment were included in the analysis. One patient in Phase I study withdrew prior to beginning protocol therapy and one patient in Surgical study was not eligible to start Phase I treatment.

→

secondary · POSTED

For the surgical study, Ki67 will be evaluated in paired pre-treatment tumor (diagnostic) and post-treatment tumor (recurrent) tissue in consenting patients to assess percent change. The percent of Ki67 in tumor tissues will be measured and the result is presented as the percent of Ki67 in post-treatment tumor minus the percent of Ki67 measured in pre-treatment tumor.

    regimen
    Patients either from Phase I stratum and received treatment from beginning, or from Surgical stratum who subsequently received Phase I defined treatment would be evaluable for MTD as long as they received sufficient Phase I defined treatment. Of the patients enrolled in Phase I stratum, 11 of them were evaluable for dose finding assessment. Of the patients enrolled in Surgical stratum, 5 of them were evaluable for dose finding assessment. Therefore, we have total 16 patients evaluable for dose finding assessment, 11 from Phase I stratum and 5 from Surgical stratum.

    Adverse events (AEs) were graded using CTCAE v5.0. AEs collected per protocol included: a) grade 1 and 2 AEs if attribution was at least possibly related to Ribociclib or Everolimus and b) all grade 3+ AEs on treatment and within 30 days off treatment. AEs were summarized in SAE and Other AE tables below. All mortality on this study were due to disease. Two patients did not started phase I protocol defined therapy and were not counted as at risk.
