This phase II Pediatric MATCH trial studies how well palbociclib works in treating patients with Rb positive solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with activating alterations (mutations) in cell cycle genes that have spread to other places in the body and have come back or do not respond to treatment. Palbociclib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Official Title

NCI-COG Pediatric MATCH (Molecular Analysis for Therapy Choice) - Phase 2 Subprotocol of Palbociclib in Patients With Tumors Harboring Activating Alterations in Cell Cycle Genes



  1. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with palbociclib with advanced solid tumors (including central nervous system [CNS] tumors), non-Hodgkin lymphomas or histiocytic disorders that harbor activating genetic alterations in cell cycle genes.


  1. To estimate the progression free survival in pediatric patients treated with palbociclib with advanced solid tumors (including CNS tumors), non-Hodgkin lymphomas or histiocytic disorders that harbor activating genetic alterations in alterations in cell cycle genes.

II. To obtain information about the tolerability of palbociclib in children and adolescents with relapsed or refractory cancer.


  1. To explore approaches to profiling changes in tumor genomics over time through evaluation of circulating tumor deoxyribonucleic acid (DNA).


Patients receive palbociclib orally (PO) once daily (QD) on days 1-21. Courses repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

  • Patient must have enrolled onto APEC1621SC and must have been given a treatment assignment to MATCH to APEC1621I based on the presence of an actionable mutation
  • Positive Rb expression by immunohistochemistry is required for study enrollment
  • Patients must have a body surface area >= 0.87 m2 at enrollment

  • Patients must have radiographically measurable disease at the time of study enrollment; patients with neuroblastoma who do not have measurable disease but have MIBG+ evaluable disease are eligible; measurable disease in patients with CNS involvement is defined as tumor that is measurable in two perpendicular diameters on magnetic resonance imaging (MRI) and visible on more than one slice
  • Note: The following do not qualify as measurable disease:
  • Malignant fluid collections (e.g., ascites, pleural effusions)
  • Bone marrow infiltration except that detected by MIBG scan for neuroblastoma
  • Lesions only detected by nuclear medicine studies (e.g., bone, gallium or positron emission tomography [PET] scans) except as noted for neuroblastoma

  • Patients must have fully recovered from the acute toxic effects of all prior anti-cancer therapy and must meet the following minimum duration from prior anti-cancer directed therapy prior to enrollment; if after the required timeframe, the numerical eligibility criteria are met, e.g. blood count criteria, the patient is considered to have recovered adequately
  • Cytotoxic chemotherapy or other anti-cancer agents known to be myelosuppressive
  • >= 21 days after the last dose of cytotoxic or myelosuppressive chemotherapy(42 days if prior nitrosourea)
  • Anti-cancer agents not known to be myelosuppressive (e.g. not associated with reduced platelet or absolute neutrophil counts [ANC] counts): >= 7 days after the last dose of agent
  • Antibodies: >= 21 days must have elapsed from infusion of last dose of antibody,and toxicity related to prior antibody therapy must be recovered to grade =< 1
  • Corticosteroids: If used to modify immune adverse events related to prior therapy, >= 14 days must have elapsed since last dose of corticosteroid
  • Hematopoietic growth factors: >= 14 days after the last dose of a long-acting growth factor (e.g. pegfilgrastim) or 7 days for short-acting growth factor; for growth factors that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur; the duration of this interval must be discussed with the study chair and the study-assigned research coordinator
  • Interleukins, interferons and cytokines (other than hematopoietic growth factors): >= 21 days after the completion of interleukins, interferon or cytokines (other than hematopoietic growth factors)
