- Age 2 to 16 years inclusive
- Histologically confirmed diagnosis of Langerhans cell histiocytosis (LCH) by central laboratory
- 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%
- Ability and willingness to provide informed consent
- Negative serum pregnancy test within 7 days before treatment for females of childbearing potential
- 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
You will not qualify if you...
- Prior chemotherapy, targeted therapy, immunotherapy, biologic therapy, or herbal anti-tumor therapy for LCH within 4 weeks or less than 5 half-lives before study drug start

- Use of growth factors affecting platelet or white blood cell function within 7 days before study drug start
- Radiotherapy or major surgery within 4 weeks before study drug start
- Participation in other interventional clinical trials within 4 weeks before study drug start
- Prior MEK 1/2 inhibitor treatment exceeding 2 weeks
- Use of anticoagulants within 7 days before study drug start in patients with brain tumors
- Prednisone or equivalent corticosteroid use below specified dose within 1 month prior, with required discontinuation 14 days before study drug start
- History or presence of other malignant tumors except certain cured skin or breast cancers
- 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
- Any other clinically significant conditions impeding study participation or safety compliance as determined by investigator
