Sponsor Protocol No.: APEC1621G

Protocol Title.: 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)

Principal Investigator: Slayton, William

Objective: 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 and have come back or do not respond to treatment. Vemurafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Description: Patients receive vemurafenib orally (PO) twice daily (BID) on day 1-28. Courses repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

Phase: Phase II

Age Group: Both

Age: 12 Months - 21 Years

Gender: All

Scope: National

Treatment (vemurafenib)
Patients receive vemurafenib PO BID on day 1-28. Courses repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

Detailed Eligibility:
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 APEC1621G based on the presence of a BRAF V600 mutation
3. 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 at enrollment must follow the dosing nomogram
4. 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
5. 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
6. 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
7. 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
