New hope for kids with resistant cancers? drug combo shows promise in early trial
NCT ID NCT04238819
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested the safety and effectiveness of the drug abemaciclib combined with other cancer medicines in 47 children and young adults whose solid tumors (including neuroblastoma) had stopped responding to standard treatments. The goal was to find the best dose and see if the combination could shrink tumors. The study lasted up to 2 years per participant and focused on managing the disease rather than providing a cure.

For abemaciclib, females should use contraception for at least 3 weeks following the last abemaciclib. For other study drugs, highly effective contraceptive precautions (and avoiding sperm donation) must be used according to their label. * Life expectancy of at least 8 weeks and able to complete at least 1 cycle of treatment. * Caregivers and participants willing to make themselves available for the duration of the trial. Exclusion Criteria: * Received allogenic bone marrow or solid organ transplant. * Received live vaccination. * Intolerability or hypersensitivity to any of the study treatments or its components. * Diagnosed and/or treated additional malignancy within 3 years prior to enrollment that may affect the interpretation of results, with the exception of curatively treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin, and/or curatively resected in situ cervical and/or breast cancers. * Pregnant or breastfeeding. * Active systemic infections. * Serious and/or uncontrolled preexisting medical condition(s) that would preclude participation in this study. * Parts A and C only: Have a bowel obstruction. * Prior treatment with drugs known to be strong inhibitors or inducers of isoenzyme cytochrome P450 3A (CYP3A) or strong inhibitors of uridine diphosphate-glucuronosyl transferase 1A1 (UGT1A1) if the treatment cannot be discontinued or switched to a different medication at least 5 half-lives prior to starting study drug. * Received prior treatment with cyclin-dependent kinase (CDK) 4 \& 6 inhibitor. * Part C only: Received prior systemic therapy for relapsed/refractory neuroblastoma. * Part C only, have received prior anti-GD2 therapy during induction phase. * Currently enrolled in any other clinical study involving an investigational product or non-approved use of a drug or device. * Has received an experimental treatment in a clinical trial within the last 30 days or 5 half-lives, whichever is longer.
