- Conditions
- Neuroblastoma

- Registration Number
- NCT05429502
- Lead Sponsor
- Novartis Pharmaceuticals
- 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 (NB), and other solid tumors, including medulloblastoma (MB), high-grade glioma (HGG), malignant rhabdoid tumors (MRT), and rhabdomyosarcoma (RMS).
- Detailed Description
The study consists of Phase I -part A (dose finding) and Phase I - part B (multiple expansion cohorts). Phase II may begin after evaluation of Phase I data (safety, tolerability, efficacy, pharmacokinetics and biomarker data), with consideration of other emerging data that may impact on the treatment landscape, before initiating Phase II in patients with relapsed or refractory NB and/or other tumors studied in Phase I.
* Phase I-Part A (dose finding): a dose finding to determine the maximum tolerated dose (MTD) and/or recommended Phase II dose (RP2D) of ribociclib in combination with TOTEM.
* Phase I- Part B (multiple expansion cohorts): it will be initiated to confirm RP2D identified from Phase I-part A. Multiple expansion cohorts have been planned to assess the preliminary antitumor activity and safety of ribociclib in combination with TOTEM in participants with r/r NB (cohort 1), MB (cohort 2), HGG (cohort 3), MRT (cohort 4), and RMS (cohort 5)
* Phase II- Double-blind, randomized, placebo controlled in r/r NB: It is a two-arm randomized, double blinded, placebo controlled, parallel group trial in participants with r/r NB.

Change from baseline in Pediatric Quality of Life Inventory (PedsQL) questionnaire (Phase II) Up to 42 months PedsQL is a generic instrument used to measure health related quality of life (HRQOL) in children and youth aged 0-25 years. The generic core instrument is available for different age groups and consist of 23 items covering 4 dimensions of HRQOL: Physical functioning (8 items), Emotional Functioning (5 items), Social Functioning (5 items) and School Functioning (5 items). Items are scored on a 5 point Likert-type response scale: 0=never a problem; 1=almost never a problem; 2=sometimes a problem; 3=often a problem; and 4=almost always a problem). Items are reverse scored and linearly transformed to a 0-100 scale, where higher scores indicating better QoL. Change from baseline in PedsQL scores will be assessed for participants in Phase II.
