NCT03220035 : 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)
PhasePhase 2
AgesMin: 12 Months Max: 21 Years
Eligibility
Inclusion Criteria:

- 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 >= 0.37 m^2 at enrollment while the 120 mg
strength tablet supply is available; patients < 0.73 m^2 must follow the dosing
nomogram; patients >= 0.73 m^2 at enrollment must follow the dosing nomogram

- Patients enrolled after the drug supply of the 120 mg strength has been exhausted must
have a body surface area >= 0.73 m^2 at enrollment and 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)

- For patients with solid tumors without known bone marrow involvement:

- Peripheral absolute neutrophil count (ANC) >= 1000/mm^3

- Platelet count >= 100,000/mm^3 (transfusion independent, defined as not receiving
platelet transfusions for at least 7 days prior to enrollment)

- Patients with known bone marrow metastatic disease will be eligible for study provided
they meet the blood counts in above criteria (may receive transfusions provided they
are not known to be refractory to red cell or platelet transfusions); these patients
will not be evaluable for hematologic toxicity

- Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70
ml/min/1.73 m^2 or a serum creatinine based on age/gender as follows:

- Age: 1 to < 2 years; maximum serum creatinine (mg/dL): male 0.6; female 0.6

- Age: 2 to < 6 years; maximum serum creatinine (mg/dL): male 0.8; female 0.8

U/L; (for the purpose of this study, the ULN for SGPT is 45 U/L)

- Serum albumin >= 2 g/dL

- Corrected QT (QTc) interval =< 480 milliseconds; Note: Patients should avoid
concomitant medication known or suspected to prolong QTc interval or cause Torsades De
Pointes; if possible, alternative agents should be considered; patients who are
receiving drugs that prolong the QTc are eligible if the drug is necessary and no
alternatives are available
