Brief Summary
This is a Phase I/II study to assess the efficacy and safety of ribociclib in combination with topotecan and temozolomide (TOTEM) in pediatric patients with relapsed or refractory (r/r) neuroblastoma ...
Detailed Description
The study is structured into two parts: Phase I - Part A (dose finding) and Phase I - Part B (multiple expansion cohorts). Phase II may commence following the evaluation of Phase I data, which include...
Eligibility Criteria
Inclusion
- Participants and/or guardian have the ability to understand and the willingness to sign a written informed consent document.
- Age ≥ 12 months and ≤ 21 years at the time of signing consent form Note: The first dose level of Phase I - part A (dose finding) will enroll participants ≥ 12 years - 21 years old, and may expand to younger participants (≥ 12 months to \< 12 years) as determined by the data.
- Histologically or cytologically confirmed solid tumors listed below that have progressed despite standard therapy or for which no effective standard therapy exists.
- Neuroblastoma (for Phase I and Phase II): Histologically proven neuroblastoma as per International Neuroblastoma Staging System (INSS); Relapsed or refractory disease; Measurable disease per International Neuroblastoma Response criteria (INRC); Bone marrow only disease not eligible; Available MYCN status before screening
- Medulloblastoma (for Phase I) regardless of genetic status (i.e. Groups 3 or 4 WNT-activated or non-WNT, SHH-activated or non-SHH)
- High-grade glioma (for Phase I): including HGG NOS, WHO Grade III or Grade IV; Glioblastoma, IDH-wildtype or IDH-mutant; Anaplastic astrocytoma, IDH-mutant; Anaplastic oligodendroglioma, IDH-mutant; Anaplastic pleomorphic xanthoastrocytoma; Diffuse midline gliomas, H3 K27-altered; Diffuse hemispheric glioma, H3 G34-mutant; Diffuse pediatric-type HGG, H3-wildtype and IDH-wildtype.
- Malignant rhabdoid tumor (for Phase I) includes diagnoses of atypical teratoid/rhabdoid tumor (AT/RT), and rhabdoid tumor of the kidney (RTK), and other soft tissues as defined by 2 of the 3 following criteria; either (1)+(2) or (1)+(3): (1) Morphology and immunophenotypic panel consistent with rhabdoid tumor; (2) Loss of SMARCB1 confirmed by immunohistochemistry; (3) Molecular confirmation of tumor-specific bi-allelic SMARCB1 loss/mutation is encouraged in cases where SMARCB1 immunohistochemistry is equivocal, and required if SMARCB1 immunohistochemistry is not available
- Rhabdomyosarcoma (for Phase I) independent of fusion status and subtype
- Participants with CNS disease who are on corticosteroids should take stable doses for at least 7 days prior to first dose of ribociclib with no plans for escalation.
- Performance status:
- ≤ 16 years: Lansky Play score ≥ 50%
- \>16 years: Karnofsky performance status ≥ 50% or ECOG \< 3
- Life expectancy of ≥ 12 weeks at the time of enrollment
- Adequate bone marrow function (bone marrow may be involved with tumor) and organ function
- Adequate hepatic, renal, cardiac function
- Females who are sexually active must agree to use highly effective contraception during and for 6 months after treatment. Additionally, females of childbearing potential must have a negative serum pregnancy test within 7 days prior to the first dose of study medication. Pregnant or lactating females are not eligible for the study.
- Sexually active males (including those that have had a vasectomy), who do not agree to abstinence, must be willing to use a condom during intercourse while on study treatment and for 6 months after stopping treatment.
Exclusion

- Not recovered from clinical and laboratory acute toxicities related to prior anti-cancer therapies
- Concurrent severe and/or uncontrolled concurrent medical conditions (serious infections or significant cardiac, pulmonary, hepatic, psychiatric, GI disease, or other organ dysfunction) that in the investigator's judgement could compromise their ability to tolerate or absorb protocol therapy or would interfere with the study procedures or results
- Clinically significant, uncontrolled heart disease and/or cardiac repolarization abnormality
- History of QTc prolongation; taking medications with a known risk to prolong the QT interval hat cannot be discontinued or replaced by safe alternative medication
- Currently taking medications that are mainly metabolized by CYP3A4/5 with a narrow therapeutic index, strong inducers or inhibitors of CYP3A4/5, herbal preparations/medications and dietary supplements
- Vaccinated with live, attenuated vaccines within 4 weeks
- Participated in a prior investigational study within 30 days
- Received prior treatment with a CDK4/6 inhibitor
- Received last dose of anticancer therapy (including experimental) within 4 weeks
- Previous myeloablative therapy with autologous hematopoietic stem cell rescue within 8 weeks
- Allogeneic stem cell transplant within 3 months
- Has last fraction of radiation within 4 weeks
- Major surgery within 2 weeks
- Pregnant or nursing (breast feeding) female participant or female participant who plans to become pregnant or breast-feed during the trial.
- Other protocol-defined inclusion/exclusion criteria may apply
