Protocol Title.: Samotolisib in Treating Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With TSC or PI3K/MTOR Mutations (A Pediatric MATCH Treatment Trial)
Principal Investigator: Slayton, William
Objective: This phase II Pediatric MATCH trial studies how well PI3K/mTOR inhibitor LY3023414 works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with TSC or PI3K/MTOR mutations that have spread to other places in the body and have come back or do not respond to treatment. PI3K/mTOR inhibitor LY3023414 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Description: This is a dose-escalation study. Patients receive PI3K/mTOR inhibitor LY3023414 orally (PO) twice daily (BID) on days 1-28. Courses repeat every 28 days for up to 2 years in the absence of disease progression or unexpected toxicity. After completion of study treatment, patients are followed up periodically.
Phase: Phase II
Age Group: Both
Age: 12 Months - 21 Years
Treatment: Treatment (PI3K/mTOR inhibitor LY3023414) Patients receive PI3K/mTOR inhibitor LY3023414 PO BID on days 1-28. Courses repeat every 28 days for up to 2 years in the absence of disease progression or unexpected toxicity.
Detailed Eligibility: INCLUSION CRITERIA: 1. Ages 12 months to 21 years old 2. Patient must have enrolled onto APEC1621SC and must have been given a treatment assignment to Molecular Analysis for Therapy Choice (MATCH) to APEC1621D based on the presence of an actionable mutation; note that treatment assignment may be to primary cohort A for patients with TSC1 or TSC2 loss of function mutations, primary cohort B for patients with other PI3K/MTOR pathway mutations, a histology specific biomarker positive expansion cohort if the criteria to open such a cohort are met, or a biomarker negative expansion cohort if the criteria to open such a cohort are met 3. Patients accruing to dose level 1 must have a body surface area >= 0.52 m^2 at the time of study enrollment; patients accruing to dose level 2 must have a body surface area >= 0.37 m^2 at the time of study enrollment; patients accruing to dose level -1 must have a body surface area >= 0.75 m^2 at the time of study enrollment 4. 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 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 - Elevated tumor markers in plasma or cerebrospinal 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 - Bone lesions without an associated soft tissue mass >= 10 mm in greatest diameter; bone lesions with an associated soft tissue mass >= 10 mm in greatest diameter imaged by computed tomography (CT) or MRI are considered measurable 5. 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 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 6. 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 count [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 ** Contact Study Team for complete eligibility details
