Failure of at least front-line therapy for LCH with evaluable disease. -OR
Diagnosis of LCH-associated neurodegenerative disease with radiologic or clinicalprogression within the past 3 months. -OR
Biopsy proven JXG, ECD, RDD, histiocytic sarcoma, or other histiocytic lesion (newlydiagnosed or relapsed/refractory disease) with evaluable active disease.
Performance Level:
-Karnofsky ≥ 50% for patients > 16 years of age and Lansky ≥ 50% for patients ≤ 16 years of age.
Adequate Hematologic Function Defined as:
ANC ≥ 0.75 x 10^9/L (unsupported/without growth factor stimulant)
Platelet count ≥ 75 x 10^9/L (unsupported/without transfusion within the past 7days).
Patients with marrow disease must have platelet count of >/= 75 x 10^9/L (transfusion support allowed) and must not be refractory to platelet transfusions.
Hemoglobin ≥ 8 g/dL (unsupported/without transfusion within the past 7 days)
Patients with marrow disease must have hemoglobin ≥ 8 g/dL (transfusion supportallowed).
Adequate Renal Function Defined as:
- Calculated creatinine clearance (or radioisotope GFR) ≥ 70 mL/min/1.73m^2 or serumcreatinine based on age/gender as follows:
Maximum Serum Creatinine (mg/dL) Age 2 to < 6 years: Male 0.8 mg/dL, Female 0.8; 6 to < 10 years: Male 1 mg/dL,Female 1; 10 to < 13 years: Male 1.2 mg/dL; Female 1.2; 13 to < 16 years: Male 1.5 mg/dL ; Female 1.4; ≥ 16 years: Male 1.7 mg/dL; Female 1.4;
Adequate Liver Function Defined as:
Bilirubin (sum of conjugated + unconjugated) ≤ 1.5 x upper limit of normal (ULN) forage
AST and ALT ≤ 3x ULN (≤ 5 x ULN for participants with liver involvement)
Serum albumin ≥ 2 g/dL.
For patients with liver disease caused by histiocytic disorder:
• Patients may be enrolled with abnormal bilirubin, AST, ALT and albumin with documentation of histiocytic liver disease.
Adequate Cardiac Function Defined as:
- Fractional shortening (FS) of ≥ 30% or ejection fraction of ≥ 50% by echocardiogramat baseline, as determined by echocardiography or multigated acquisition scan (MUGA)within 28 days prior to enrollment. Depending on institutional standard, either FSor LVEF is adequate for enrollment if only one value is measured; if both values aremeasured, then both values must meet criteria above
Pregnancy/Birth Control
Female patients of childbearing potential require a negative urine or serumpregnancy test for eligibility and again at database registration, if more than 2weeks has elapsed.
Female patients of childbearing potential must agree to follow the contraceptiverequirements using two forms of effective contraceptive methods for the duration ofthe study treatment. Male patients with sexual partners who are pregnant or whocould become pregnant (i.e., women of child-bearing potential) must agree to use twoforms of effective methods of contraception (one of which must be a barrier method)during the treatment period and for at least 3 months after the last dose of thestudy drug to avoid pregnancy and/or potential adverse effects on a developingembryo. Agreement to true abstinence (not periodic abstinence or withdrawal method)is an acceptable method of birth control.
Exclusion
EXCLUSION CRITERIA:
Prior and Concomitant Use of Drugs with CYP3A4 inducing/inhibiting activity: Patienttaking strong inducers or inhibitors of CYP3A4 within 14 days prior to studyenrollment, including but not limited to the following: erythromycin,clarithromycin, ketoconazole, azithromycin, itraconazole, grapefruit juice or St.John's wort.
Prior Therapy Restrictions Completion of previous chemotherapy, immunotherapy,radiotherapy, or targeted therapy for LCH (or other histiocytic disorder) at least 28 days (except where specified below) prior to study enrollment, with resolution ofall associated toxicity to ≤ Grade 1 prior to study enrollment (exception foralopecia and ototoxicity which do not need to be resolved ≤ Grade 1). Patients musthave fully recovered from the acute toxic effects of all prior anti-cancer therapyand must meet the following minimum duration from prior anti-cancer directed therapyprior to enrollment. If after the required timeframe, the laboratory eligibilitycriteria are met, the patient is considered to have recovered adequately.
Radiation therapy within the 28 days prior to enrollment.
Any prior treatment with Cobimetinib.
Treatment with a long-acting hematopoietic growth factor within 14 days priorto initiation of study drug or a short-acting hematopoietic growth factorwithin 7 days prior to enrollment.
Treatment with hormonal therapy (except hormone replacement therapy or oralcontraceptives), immunotherapy, biologic therapy, investigational therapy, orherbal cancer therapy within 28 days or < 5 half-lives, whichever is longer,prior to study enrollment.
Treatment with high-dose chemotherapy and stem-cell rescue (autologous stemcell transplant) or allogeneic stem cell transplant within 90 days prior toenrollment. Anti-GVHD agents post-transplant: Patients who are receivingcyclosporine, tacrolimus or other agents to prevent graft-versus-host diseasepost bone marrow transplant are not eligible for this trial.
For patients with brain tumors (intracranial masses), use of anticoagulantswithin 7 days prior to enrollment.
Corticosteroid therapy <0.5 mg/kg/day averaged during the month prior to studyenrollment is permissible but must be discontinued fourteen (14) days prior toenrollment. Patients with documented brain lesions receiving corticosteroidsfor management of cerebral edema must be on a stable dose for fourteen (14)days prior to enrollment.
Patient has received treatment with investigational therapy within 4 weeksprior to initiation of study drug.
Patients taking anticoagulants or have a pre-existing bleeding disorderunrelated to histiocytic disease.
Exclusions for other illness
Other active malignancy or history of secondary malignancy.
Refractory nausea and vomiting, malabsorption, external biliary shunt
Infection: Patients who have a known active infection (excluding documentedfungal infection of the nail beds) within 28 days prior to enrollment that hasnot completely resolved.
Major surgical procedure or significant traumatic injury within 28 days priorto enrollment, or anticipation of need for major surgical procedure during thecourse of the study. Placement of a vascular access device or minor surgery ispermitted within fourteen (14) days prior to study enrollment (provided thatthe wound has healed).
History of significant bowel resection that would preclude adequate absorptionor other significant malabsorptive disease.
History of pneumonitis.
Ophthalmologic considerations: Patients with known significant ophthalmologicconditions or known risk factors for retinal vein occlusion are not eligible.Specifically, patients with a history of retinal vein occlusion (RVO), retinaldetachment, retinal pathology on ophthalmologic exam, retinopathy ofprematurity, central serous chorioretinopathy (CSSCR), neovascular retinopathy,intraocular pressure > 21 mmHg, and predisposing factors to RVO (e.g.,uncontrolled hypertension, diabetes, or hyperlipidemia, coagulopathy) will beexcluded. Patients with longstanding and stable ophthalmologic findingssecondary to existing conditions are eligible with appropriate writtendocumentation and approval from Study Chair.
History of solid organ transplantation: Patients who have received a priorsolid organ transplantation are not eligible.
Any other disease, metabolic or psychological dysfunction, physical examinationfinding, or clinical laboratory finding giving reasonable suspicion of adisease or condition that in the opinion of the investigator contraindicatesuse of an investigational drug or places the patient at unacceptable risk fromtreatment complications.
History of clinically significant cardiac dysfunction, including the following:
Clinically significant cardiac arrhythmias including brady-arrhythmias and/orpatients who require anti-arrhythmic therapy (with the exception of betablockers or digoxin). Patients with controlled atrial fibrillation are notexcluded.
Unstable arrhythmia
Unstable angina, or new-onset angina within 3 months prior to initiation ofstudy treatment
Symptomatic congestive heart failure, defined as New York Heart AssociationClass II or higher
Myocardial infarction within 3 months prior to initiation of study treatment
Known chronic human immunodeficiency virus (HIV).
History of Grade ≥ 2 CNS hemorrhage or history of any CNS hemorrhage within 28 daysof enrollment.
Female patients who are pregnant or lactating. Pregnant or lactating women will notbe entered on this study because there is no available information regarding humanfetal or teratogenic toxicities.
