  • Central or local laboratory biomarker testing for specified genes if sufficient tissue or blood samples are available
  • Prior treatment with at least first-line systemic therapy including vinblastine or equivalent for at least 2 weeks, or inability to tolerate chemotherapy due to severe toxicity
  • Refractory or relapsed LCH defined by specific criteria including treatment failure, disease reactivation, persistent mutated gene positivity, CNS involvement, or bone marrow/HLH involvement
  • Presence of evaluable lesions based on PET response criteria
  • Recovery from acute toxic effects of prior anti-tumor therapy with toxicities ≤ grade 1 (except alopecia and ototoxicity)
  • Expected survival of at least 3 months
  • Lansky (≤15 years) or Karnofsky (≥16 years) performance status score ≥ 50%

  • Agreement to use effective contraception during treatment and for 90 days after last dose (dual barrier methods for females; males to refrain from sperm donation)
  • Adequate bone marrow function with specified blood count thresholds, or inclusion based on investigator judgment if low counts due to underlying disease
  • Adequate liver and kidney function within specified laboratory limits, with possible inclusion based on investigator judgment
  • Coagulation parameters (INR and APTT) ≤ 1.5 times upper limit of normal
Not Eligible

  • Uncontrolled hypertension (≥ 95th percentile for age, height, and sex)
  • Dysphagia, active gastrointestinal disease, malabsorption syndrome, or conditions affecting drug absorption
  • History or current retinal vein obstruction, retinal pigment epithelial detachment, glaucoma, or significant eye exam abnormalities
  • Interstitial pneumonia or significant radiation pneumonitis except due to primary disease
  • Specified cardiac conditions including QTcF >470 ms, NYHA class ≥2 heart failure, significant arrhythmias, coronary heart disease, cardiomyopathy, severe valvular disease, or LVEF <50%
  • Active bacterial, fungal, or viral infections including active hepatitis B or C, or HIV
  • Known allergies to study drug, MEK1/2 inhibitors, or excipients
  • Genetic mutations MAP2K1 exon 3 deletions or deletion-insertion mutations in tumor tissue
