Ensartinib in Treating Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With ALK or ROS1 Genomic Alterations (A Pediatric MATCH Treatment Trial)

PRIMARY OBJECTIVE:

I. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with ensartinib with advanced solid tumors (including central nervous system [CNS] tumors), non-Hodgkin lymphomas or histiocytic disorders that harbor ALK or ROS1 fusions or that harbor ALK missense mutations.

SECONDARY OBJECTIVES:

I. To estimate the progression free survival in pediatric patients treated with ensartinib with advanced solid tumors (including CNS tumors), non-Hodgkin lymphomas or histiocytic disorders that harbor ALK or ROS1 fusions or that harbor ALK missense mutations.

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

III. To provide preliminary estimates of the pharmacokinetics of ensartinib in children with relapsed or refractory cancer.

EXPLORATORY OBJECTIVES:

I. To evaluate other biomarkers as predictors of response to ensartinib and specifically, whether tumors that harbor different missense mutations or fusions (including the crizotinib resistant F1174L ALK variant) will demonstrate differential response to ensartinib treatment.

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

OUTLINE:

Patients receive ensartinib orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days for 2 years (up to 26 cycles) in the absence of disease progression or unacceptable toxicity. Patients undergo an x-ray, computed tomography (CT) scan, magnetic resonance imaging (MRI), positron emission tomography (PET) scan, radionuclide imaging, and/or bone scan, as well as a bone marrow aspiration and/or biopsy during screening and on study. Patients also undergo blood sample collection on study.

After completion of study treatment, patients are followed up for 30 days.

Inclusion criteria

• Patient must have enrolled onto APEC1621SC//NCI-2017-01251 and must have been given a treatment assignment to Molecular Analysis for Therapy Choice (MATCH) to APEC1621F/NCI-2017-01243 based on the presence of an actionable mutation as defined in APEC1621SC/ NCI-2017-01251

• 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

• 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)

• Radiation therapy (XRT)/external beam irradiation including protons: >= 14 days after local XRT; >= 150 days after TBI, craniospinal XRT or if radiation to >= 50% of the pelvis; >= 42 days if other substantial none marrow (BM) radiation

• Note: Radiation may not be delivered to "measurable disease" tumor site(s) being used to follow response to subprotocol treatment
• Radiopharmaceutical therapy (e.g., radiolabeled antibody, 131I-MIBG): >= 42 days after systemically administered radiopharmaceutical therapy
• Patients must not have received prior exposure to ensartinib; prior treatment with other ALK inhibitors is permitted given that at least 5 half-lives or 21 days have elapsed since therapy discontinuation, whichever is greater
