About this study

Official title: Molecularly-Driven Doublet Therapy for All Children With Refractory or Recurrent CNS Malignant Neoplasms and Young Adults With Refractory or Recurrent SHH Medulloblastoma

Approximately 90% of children with malignant brain tumors that have recurred or relapsed after receiving conventional therapy will die of disease. Despite this terrible and frustrating outcome, continued treatment of this population remains fundamental to improving cure rates. Studying this relapsed population will help unearth clues to why conventional therapy fails and how cancers continue to resist modern advances. Moreover, improvements in the treatment of this relapsed population will lead to improvements in upfront therapy and reduce the chance of relapse for all. Novel therapy and, more importantly, novel approaches are sorely needed. This trial proposes a new approach that evaluates rational combination therapies of novel agents based on tumor type and molecular characteristics of these diseases. The investigators hypothesize that the use of two predictably active drugs (a doublet) will increase the chance of clinical efficacy. The purpose of this trial is to perform a limited dose escalation study of multiple doublets to evaluate the safety and tolerability of these combinations followed by a small expansion cohort to detect preliminary efficacy. In addition, a more extensive and robust molecular analysis of all the participant samples will be performed as part of the trial such that we can refine the molecular classification and better inform on potential response to therapy. In this manner the tolerability of combinations can be evaluated on a small but relevant population and the chance of detecting antitumor activity is potentially increased. Furthermore, the goal of the complementary molecular characterization will be to eventually match the therapy with better predictive biomarkers.

PRIMARY OBJECTIVES:

  • To determine the safety and tolerability and estimate the maximum tolerated dose/recommended phase 2 dose (MTD/RP2D) of combination treatment by stratum.
  • To characterize the pharmacokinetics of combination treatment by stratum.

SECONDARY OBJECTIVE:

  • To estimate the rate and duration of objective response and progression free survival (PFS) by stratum.
Read the detailed description

Patients will be stratified by the molecular and histologic characteristics of their tumor to one of three treatment strata.

STRATUM A:

  • Combination Treatment: ribociclib and gemcitabine.
  • Patient Population: Participants with a diagnosis of refractory or recurrent medulloblastoma (Group 3/4) or refractory or recurrent ependymoma (including: ependymoma, not otherwise specified (NOS), WHO Grade III; ependymoma, RELA fusion positive; anaplastic ependymoma; ependymoma, NOS, WHO grade II).

STRATUM B:

  • Combination Treatment: ribociclib and trametinib.
  • Patient Population: Participants with a diagnosis of one of the following refractory or recurrent CNS diseases: medulloblastoma [sonic hedgehog (SHH)], medulloblastoma (WNT), high grade glioma (including: high grade glioma, (NOS), WHO Grade III or IV; anaplastic astrocytoma, IDH mutant; glioblastoma, IDH-wildtype; glioblastoma, IDH-mutant; diffuse midline glioma, H3K27-mutant; anaplastic oligodendroglioma, IDH mutant and 1p/19q-codeleted; anaplastic pleomorphic xanthoastrocytoma) or select central nervous system (CNS) embryonal tumors (including: embryonal tumors with multilayered rosettes, C19MC-altered; embryonal tumors with multilayered rosettes, not otherwise specified (NOS); medulloepithelioma; CNS neuroblastoma; CNS ganglioneuroblastoma; CNS embryonal tumor, NOS; atypical teratoid/rhabdoid tumor; CNS embryonal tumor with rhabdoid features).

STRATUM C:

  • Combination Treatment: ribociclib and sonidegib.
  • Patient Populations: Participants with refractory or recurrent medulloblastoma (SHH) >6 months off smoothened inhibitor, presence of 9q loss or PTCH1 mutant, skeletally mature.

The rolling 6 design will be used separately in each stratum to estimate the MTD or RP2D and determine the dose-limiting toxicity (DLT) of the combination of escalating doses. Therapy will be administered in cycles of 28 days and may be continued for up to 24 months (26 cycles) in the absence of disease progression or unacceptable toxicity. Stratum A participants may continue therapy past 24 months in absence of disease progression or unacceptable toxicity.

Patients will receive doublet therapy in cycles of 28 days. The dose-limiting toxicity (DLT)-evaluation period will consist of the first cycle (i.e. first 4 weeks of therapy). Research participants will be evaluated at least once a week during the DLT-evaluation period and at regular intervals thereafter. Standard (e.g., physical exam, blood tests, and disease evaluations) tests will be obtained at regular intervals. Research-associated evaluations (e.g., pharmacokinetic studies, etc.) will also be obtained during therapy. Treatment may be continued for up to 2 years in the absence of disease progression or unacceptable toxicity. Stratum A participants may continue past 2 years in the absence of disease progression or unacceptable toxicity.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Estimate the Maximum tolerated dose (MTD)/Recommended Phase 2 Dose (RP2D) of each doublet by stratum

    The MTD is empirically 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. The MTD estimate will not be available, if the lowest dose level studied is too toxic or the highest dose level studied is considered safe. In the latter case, the highest studied safe dose will be considered the recommended phase 2 dose (RP2D). The MTD estimation will be limited to evaluable patients and toxicity assessments from course 1 (28 days).

    Measured: 1 month after start of therapy

  2. Pharmacokinetics of combination treatment: Stratum A

    Plasma concentration will be provided.

    Measured: Course 1: Days -1, 0, 1 and 15 and 16; Course 2: Day 1

  3. Pharmacokinetics of combination treatment: Stratum B

    Plasma concentration will be provided.

    Measured: Course 1: Days 1, 2, 3, 14 and 15

  4. Pharmacokinetics of combination treatment: Stratum C

    Plasma concentration will be provided.

    Measured: Course 1: Days -1, 0, 1, 2, 21, 22 and 28; Course 2: Day 1

Secondary outcomes (2)

  1. Response rate by stratum

    The response rate, defined as the rate of complete response (CR) or partial response (PR), and long-term stable disease (SD) will be calculated as the percentage of confirmed responders among all response assessable patients. These rates as well as their exact confidence intervals will be provided and will be summarized by each response category (i.e., CR, PR, and SD). Descriptive summaries of response per dose level may also be provided. Subjects without an assessment will be considered non-responders.

    Measured: Up to 1 year after completion of therapy (up to 3 years after start of therapy)

  2. Duration of objective response by stratum

    Duration of response defined as the time from the initial documented response (CR or PR) to the first confirmed progressive disease (PD). We will use progression free survival (PFS) for describing duration of SD. Subjects without a documented progression will be censored at the time of their last tumor assessment. Duration of Response will be assessed using the Kaplan-Meier method to calculate the median time as well as the proportion remaining progression free at given time points. The corresponding 95% confidence intervals will be presented.

    Measured: Up to 1 year after completion of therapy (up to 3 years after start of therapy)

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 22 inclusion and 39 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Estimate the Maximum tolerated dose (MTD)/Recommended Phase 2 Dose (RP2D) of each doublet by stratum (time frame: 1 month after start of therapy). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03434262.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 May 2024.
