Vemurafenib in Treating Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With BRAF V600 Mutations (A Pediatric MATCH Treatment Trial)

Completed · Phase 2

Conditions studied: Advanced Malignant Solid Neoplasm, Ann Arbor Stage III Childhood Non-Hodgkin Lymphoma, Ann Arbor Stage IV Childhood Non-Hodgkin Lymphoma, Ependymoma, Ewing Sarcoma, Hepatoblastoma, Langerhans Cell Histiocytosis, Malignant Germ Cell Tumor, Malignant Glioma, Osteosarcoma, Peripheral Primitive Neuroectodermal Tumor, Recurrent Childhood Central Nervous System Neoplasm, Recurrent Childhood Non-Hodgkin Lymphoma, Recurrent Malignant Solid Neoplasm, Recurrent Neuroblastoma, Refractory Malignant Solid Neoplasm, Refractory Neuroblastoma, Refractory Non-Hodgkin Lymphoma, Refractory Primary Central Nervous System Neoplasm, Rhabdoid Tumor, Rhabdomyosarcoma, Soft Tissue Sarcoma, Wilms Tumor

In brief

This phase II Pediatric MATCH trial studies how well vemurafenib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with BRAF V600 mutations that have spread to other places in the body (advanced) and have come back (recurrent) or do not respond to treatment (refractory). Vemurafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Who can join

Age: 1 and older, up to 21. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patient must have enrolled onto APEC1621SC and must have been given a treatment assignment to Molecular Analysis for Therapy Choice (MATCH) to APEC1621G based on the presence of a BRAF V600 mutation
• Patients must have a body surface area >= 0.55 m\^2 at enrollment; patients < 0.73 m\^2 must follow the dosing nomogram; patients >= 0.73 m\^2 at enrollment must follow the dosing nomogram
• 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
• 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
• 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
• 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)
• Stem cell Infusions (with or without total-body irradiation [TBI]):
• Allogeneic (non-autologous) bone marrow or stem cell transplant, or any stem cell infusion including donor lymphocyte infusion (DLI) or boost infusion: >= 84 days after infusion and no evidence of graft versus host disease (GVHD)
• Autologous stem cell infusion including boost infusion: >= 42 days
• Cellular therapy: >= 42 days after the completion of any type of cellular therapy (e.g. modified T cells, natural killer [NK] cells, dendritic cells, etc.)
• 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 bone 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, iobenguane I-131 [131I-MIBG]): >= 42 days after systemically administered radiopharmaceutical therapy
• Patients must not have received prior exposure to a BRAF inhibitor (e.g. vemurafenib, dabrafenib or encorafenib)

You may not qualify if…

• Pregnant or breast-feeding women will not be entered on this study due to risks of fetal and teratogenic adverse events as seen in animal/human studies; pregnancy tests must be obtained in girls who are post-menarchal; males or females of reproductive potential may not participate unless they have agreed to use an effective contraceptive method, for the duration of study treatment and for 6 months after the last dose of vemurafenib
• Patients receiving corticosteroids who have not been on a stable or decreasing dose of corticosteroid for at least 7 days prior to enrollment are not eligible; if used to modify immune adverse events related to prior therapy, >= 14 days must have elapsed since last dose of corticosteroid
• Patients who are currently receiving another investigational drug are not eligible
• Patients who are currently receiving other anti-cancer agents are not eligible
• Patients who are receiving cyclosporine, tacrolimus or other agents to prevent graft-versus-host disease post bone marrow transplant are not eligible for this trial
• Patients who are currently receiving drugs that are moderate to strong inducers or inhibitors of CYP3A4 are not eligible; moderate to strong inducers or inhibitors of CYP3A4 should be avoided from 14 days prior to enrollment to the end of the study; Note: CYP3A4 inducing anti-epileptic drugs and dexamethasone for CNS tumors or metastases, on a stable dose, are allowed
• Patients who are currently receiving drugs that are inhibitors or inducers of p-glycoprotein (P-gp) or adenosine triphosphate (ATP)-binding cassette, subfamily G, member 2 (ABCG2 [BCRP]) are not eligible
• Patients with known active cutaneous squamous cell carcinoma (includes keratoacanthoma or mixed keratoacanthoma subtype) are not eligible; patients who have fully excised lesions with dermatologic confirmation of absence of disease are eligible
• Patients with low grade glioma patients (World Health Organization [WHO] grades I and II) are not eligible
• Patients who have an uncontrolled infection are not eligible
• Patients who have received a prior solid organ transplantation are not eligible
• Patients who in the opinion of the investigator may not be able to comply with the safety monitoring requirements of the study are not eligible
