This study investigated the BET inhibitor drugs BMS-986158 and BMS-986378 in childhood cancers (solid tumors, lymphoma and central nervous system tumors). Patients aged 21 or younger with relapsed or refractory cancer who could swallow capsules were eligible. The study was carried out in Phase 1 and has been completed.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.

Patients must meet the following minimum washout periods prior to enrollment: * Myelosuppressive chemotherapy: At least 21 days after the last dose of myelosuppressive chemotherapy (42 days for nitrosourea or mitomycin C). * Radiotherapy: * At least 14 days after local XRT (small port, including cranial radiation); * At least 90 days must have elapsed after prior TBI, or if \>50% radiation of pelvis; * At least 180 days must have elapsed after prior craniospinal XRT; * At least 42 days must have elapsed if other substantial BM radiation; * At least 42 days must have passed since last MIBG or other radionuclide therapy. * Small molecule biologic therapy: At least 7 days following the last dose of a small molecule biologic agent. For agents with known adverse events occurring beyond 7 days, this duration must be extended beyond the time in which adverse events are known to occur. If extended duration is required, this must be discussed with and approved by the overall PI. * Monoclonal antibody: At least 28 days must have elapsed after the last dose of therapeutic monoclonal antibody. * Myeloid growth factors: At least 14 days following the last dose of long-acting growth factor (e.g. Neulasta) or 7 days following short-acting growth factor. * Autologous hematopoietic stem cell transplant and stem cell boost: Patients must be at least 60 days from day 0 of an autologous stem cell transplant or autologous stem cell boost. * Cellular therapies (including CAR-T cells) and other non-cellular, non-antibody immunotherapies (e.g., vaccines): At least 42 days must have elapsed after last dose. * Major Surgery: At least 2 weeks from prior major surgical procedure. Note: Major surgical procedure will be considered all surgical procedures aside from the following: Biopsy; central line placement/removal; bone marrow aspirate/biopsy; lumbar puncture; dental procedures; gastrostomy tube placement; and VP shunt placement/revision. * BET inhibitors: Patients must not have received prior treatment with a BET inhibitor, except patients with CNS tumors or CNS metastasis previously treated on Arm 1 of the trial who discontinued protocol therapy due to disease progression and not due to toxicity. Such patients may participate in Arm 2 of the trial. * Participants must have normal organ function as defined below. * Bone Marrow Function * For Patients without Documented Bone Marrow Involvement by Disease: * Hemoglobin \> 8 g/dL (may be transfused) * Absolute neutrophil count ≥ 1,000 /uL * Platelets ≥ 100,000 /uL and transfusion independent, defined as not receiving a platelet transfusion for at least 5 days prior to CBC documenting eligibility. * For Patients with Documented Bone Marrow Involvement by Disease: * Hemoglobin \> 8 g/dL (may be transfused) * Absolute neutrophil count ≥ 750 /uL * Platelets ≥ 75,000 /uL and transfusion independent, defined as not receiving a platelet transfusion for at least 5 days prior to CBC documenting eligibility. * Hepatic Function: * Total bilirubin ≤ 1.5 x upper limit of normal for age (patients with known Gilbert's may be considered after discussion with overall PI and if direct bilirubin is at or below the upper limit of normal for age) * ALT (SGPT) ≤ 3 x upper limit of normal (135 U/L) For the purpose of this study, the ULN for ALT is 45 U/L * Serum albumin \> 2 g/dL * Adequate Pancreatic Function: --Lipase \< upper limit of normal * Adequate GI Function: --Diarrhea \< grade 1 by CTCAE version 5 * Coagulation Factors: * International Normalized Ratio (INR) \< 1.5 * Partial thromboplastin time (PTT) \< 1.5 times upper limit of normal * For patients having labs drawn via heparinized catheters, it is important to request heparin-absorbed values. * Adequate Cardiac Function: --QTc \< 480 msec * Renal Function: * A serum creatinine within protocol limits based on age/sex. OR * Creatinine clearance ≥ 60 mL/min/1.73 m2 for participants with creatinine levels greater than the above age/sex maximum allowed values. * Able to swallow intact capsules (BMS-986158) or tablets (BMS-986378, also known as CC-90010). * Patient (or parent or legally authorized representative, if minor) is able to understand and willing to provide informed consent, using an institutionally approved informed consent procedure. * Participants of childbearing or child-fathering potential must agree to use adequate contraception throughout their participation following the guidance in Appendix H. Exclusion Criteria: * Prior solid organ or allogeneic stem cell transplantation. * Patients with primary or metastatic CNS tumors are not eligible for Arm 1, except: --Patients with a history of CNS metastatic disease that has been resected and/or radiated without evidence of active CNS disease for 3 months preceding enrollment; NOTE: patients with primary CNS tumors or solid tumors with active CNS metastases will be eligible for Arm 2. * Patients receiving any of the following prohibited foods and medications: * Agents listed in Appendix B within 7 days prior to enrollment * Grapefruit or Seville oranges and/or their juices within 7 days prior to enrollment * Non-steroidal anti-inflammatory drugs, oral anticoagulants, and therapeutic heparins (unfractionated or low molecular weight heparin) at the time of enrollment. Note: Use of heparin to maintain patency of a central or peripheral catheter is allowed * Other investigational agents being administered under an IND. * Pregnant participants will not be entered on this study given that the effects of BMS-986158 and BMS-986378 (CC-90010) on the developing human fetus are unknown. Female participants of childbearing potential must have a documented negative pregnancy exam within 24 hours prior to dosing. * Breastfeeding mothers are not eligible, because there is an unknown risk for adverse events in nursing infants secondary to treatment of the mother with BMS-986158 or BMS-986378 (CC-90010). * History of allergic reactions attributed to compounds of similar chemical or biologic composition to BMS-986158 or BMS-986378 (CC-90010). * Uncontrolled intercurrent illness including, but not limited to, ongoing or uncontrolled infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. * Patients with a known history of HIV, hepatitis B, and/or hepatitis C (testing not required as part of screening). * Patients with gastrointestinal disease or disorder that could interfere with absorption of BMS-986158 or BMS-986378 (CC-90010), such as bowel obstruction or inflammatory bowel disease. * For Arm 1: Patients with BSA \< 0.3 m2 for all dose levels except Dose Level -2 or -2i for which patients with BSA \< 0.71 m2 will be excluded due to dose rounding constraints. * For Arm 2: Patients with BSA \< 0.65 m2.
