Non Hodgkin Lymphoma Clinical Trial
Selpercatinib for the Treatment of Advanced Solid Tumors, Lymphomas, or Histiocytic Disorders With Activating RET Gene Alterations, a Pediatric MATCH Treatment Trial
This phase II pediatric MATCH trial studies how well selpercatinib works in treating patients with solid tumors that have spread to other places in the body (advanced), lymphomas, or histiocytic disorders that have activating RET gene alterations. Selpercatinib may block the growth of cancer cells that have specific genetic changes in an important signaling pathway (called the RET pathway) and may reduce tumor size.
I. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with selpercatinib (LOXO-292) with advanced solid tumors (including central nervous system [CNS] tumors), lymphomas or histiocytic disorders that harbor activating genetic alterations in the RET pathway.
I. To estimate the progression free survival in pediatric patients treated with selpercatinib (LOXO-292) with advanced solid tumors (including CNS tumors), lymphomas or histiocytic disorders that harbor activating genetic alterations in the RET pathway.
II. To obtain information about the tolerability of selpercatinib (LOXO-292) in children and adolescents with relapsed or refractory cancer.
I. To explore approaches to profiling changes in tumor genomics over time through evaluation of circulating tumor deoxyribonucleic acid (DNA).
Patients receive selpercatinib orally (PO) twice daily (BID) on days 1-28 on study. Treatment repeats every 28 days for up to 26 cycles (2 years) in the absence of disease progression or unacceptable toxicity. Patients may also undergo positron emission tomography (PET), computed tomography (CT), magnetic resonance imaging (MRI), PET/CT, PET/MRI, and/or CT/MRI, scintigraphy, and x-ray imaging throughout the trial.
After completion of study treatment, patients are followed for 30 days, then periodically thereafter.
Patient must have enrolled onto APEC1621SC and must have been given a treatment assignment to MATCH to APEC1621N based on the presence of an actionable mutation
Patients must be >= 12 months and =< 21 years of age at the time of study enrollment
Patients must have radiographically measurable disease at the time of study enrollment. Patients with neuroblastoma who do not have measurable disease but have metaiodobenzylguanidine (MIBG) positive (+) evaluable disease are eligible. Measurable disease in patients with CNS involvement is defined as any lesion that is at minimum 10 mm in one dimension on standard MRI or CT
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
Elevated tumor markers in plasma or cerebral spinal fluid (CSF)
Previously radiated lesions that have not demonstrated clear progression post radiation
Leptomeningeal lesions that do not meet the measurement requirements for Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
Karnofsky >= 50% for patients > 16 years of age and Lansky >= 50 for patients =< 16 years of age. Note: Neurologic deficits in patients with CNS tumors must have been relatively stable for at least 7 days prior to study enrollment. Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score
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

>= 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 [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

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
