Objective Response Rate (ORR) Evaluated by Independent Review Committee (IRC) Based on PET Response Criteria (PRC)
ORR Evaluated by Independent Review Committee (IRC) Based on PET Response Criteria (PRC) is defined as the percentage of participants who achieved a best overall response of CMR or PMR assessed by IRC .

Study Arms (1)
FCN-159
EXPERIMENTAL
Experimental: FCN-159 Dosage form:tablet Specification: 1mg,4mg Dose: FCN-159 5mg/m² (Maximum dose does not exceed 8mg), orally, once daily
If sufficient tumor tissue samples and peripheral blood samples are available, central laboratory biomarker testing is required as follows: including but not limited to ERBB3, BRAF, ARAF, HRAS, KRAS, NRAS, MEK (MAP2K1 and MAP2K2), and other MEK upstream genes.If inability to get tissue, the gene testing results from a local laboratory also can be accepted.
Patients who have received at least prior first-line systemic treatment, defined as treatment including vinblastine (VBL) and glucocorticoids for at least 2 weeks. VBL can be substituted with vincristine (VCR) or vindesine (VDS). Alternatively, patients may be unable to tolerate chemotherapy due to severe chemotherapy toxicity. Inability to tolerate chemotherapy is defined as one of the following: Severe liver impairment (liver enzyme elevation ≥ 5 × upper limit of normal (ULN) and bilirubin elevation ≥ 1.5 × ULN), severe neurotoxicity related to vinca alkaloids, chemotherapy-related intracranial hypertension, or grade 4 bone marrow depression with severe infection (sepsis, severe pneumonia, etc.) after chemotherapy.
Refractory/relapsed LCH is defined as the presence of one of the following:
Failure of prior treatment, i.e., no regression in risk organs after at least 2 weeks of systemic treatment, or overall evaluation of AD-progression or AD-mix;
Initial response of the disease to first or second-line systemic treatment is NAD or AD-better or AD-stable, followed by disease reactivation after maintenance therapy for more than 3 months. Second-line treatment includes cytarabine and/or cladribine.
Persistent mutated gene positive in plasma free DNA testing during prior treatment (confirmed by 2 consecutive tests) or retest positive after treatment discontinuation;
Lack of regression in the affected central nervous system (including the pituitary gland) after treatment;
Presence of bone marrow involvement and/or hemophagocytic lymphohistiocytosis (HLH);
Presence of evaluable lesions based on PET response criteria (PRC).
Patients who have to have recovered from all acute toxic effects of prior anti-tumor therapy, and all relevant toxicities must be ≤ grade 1 (except for alopecia and ototoxicity).
Expected survival at least ≥ 3 months;
Lansky (≤ 15 years old) and Karnofsky (≥ 16 years old) performance status scores should be ≥ 50%, as shown in Appendix 4.
Patients or their legal guardians must be able to understand and willingly sign a written informed consent form.
+3 more criteria
You may not qualify if:
Patients who have received any of the following prior treatments:
Chemotherapy, targeted therapy, immunotherapy, biologic therapy, or herbal anti-tumor therapy for LCH within 4 weeks or \< 5 half-lives (whichever is shorter)before the start of the study drug .
Strong CYP3A4, CYP2C8, and CYP2C9 inhibitors or inducers within 14 days before the start of the study drug, except for topical skin application.
Gowth factors that promote platelet or white blood cell count or function within 7 days before the start of the study drug.
Radiotherapy or major surgical treatment (including craniotomy, thoracotomy, laparotomy, open bone or joint surgery, etc.) within 4 weeks before the start of the study drug.
Participated in other interventional clinical trials within 4 weeks before the start of the study drug.
MEK 1/2 inhibitors (those who have received this treatment for a short period of ≤ 2 weeks may be included).
Anticoagulants within 7 days before the start of the study drug for patients with brain tumors (intracranial masses).
Prednisone treatment \< 0.5mg/kg/day (or equivalent dose of other corticosteroids) is allowed within one month before enrollment, but must be discontinued 14 days before the start of the study drug. Patients with brain lesions receiving corticosteroid therapy for brain edema must maintain a stable dose for 14 days before enrollment. Hormone replacement therapy is allowed for patients with hypopituitarism due to primary disease involvement of the pituitary.
Patients with a history of other malignant tumors or concurrent other malignant tumors (excluding cured non-melanoma skin basal cell carcinoma, ductal carcinoma in situ of the breast, or cervical carcinoma in situ).
Uncontrolled hypertension (with medication treatment): Blood pressure (BP) greater than or equal to the 95th percentile for age, height, and sex, as described in Appendix 6.
Patients with dysphagia, active gastrointestinal disease, malabsorption syndrome, or other conditions that may affect the absorption of the study drug.
Prior or current history of retinal vein obstruction (RVO), retinal pigment epithelial detachment (RPED), glaucoma, and other clinically significant abnormal ophthalmologic examination results.
Interstitial pneumonia, including clinically significant radiation pneumonitis. Except for interstitial pneumonia caused by pulmonary involvement of the primary disease.
Patients will be excluded if their cardiac function or comorbidities meet any of the following criteria:
