Inclusion Criteria
  1. ≥ 18 years old and ≤ 70 years old.
  2. Patients must be diagnosed with symptomatic NF1-related plexiform neurofibromas (PNs) and require systemic therapy at the investigator's discretion.
  3. Presence of measurable lesions, defined as ≥ 3 cm in length in at least one dimension, which can be evaluated for efficacy by MRI.

  5. Patients with adequate organ and bone marrow functions.
Exclusion Criteria
  1. NF1-related malignancies requiring chemotherapy, radiotherapy, or surgery, such as medium to high grade optic glioma or malignant peripheral nerve sheath tumor.

  2. Patients with a history of or concurrently with other malignancies (excluding cured non-melanoma skin basal cell carcinoma, breast cancer in situ or cervical cancer in situ, and other malignancies without evidence of disease within 5 years).

  3. Patients who cannot undergo MRI and/or have contraindications to MRI.

  4. Patients with previous or current retinal vein obstruction (RVO), retinal pigment epithelial detachment (RPED), glaucoma, and other abnormal ophthalmic examination with clinical significance.

  5. Interstitial pneumonia, including clinically significant radiation pneumonia.

  6. Cardiac function or combined diseases meet one of the following conditions:

    1. QTcF value of > 470 milliseconds; patients with risk factors for QTcF prolongation or patients receiving drugs that prolong the QTcF interval.
    2. Congestive heart failure per New York Heart Association (NYHA) classification ≥ Class 3.
    3. Arrhythmias with clinical significance.
    4. Known concurrent clinically significant coronary artery disease, cardiomyopathy, and severe valvular disease.

Primary Outcome Measures
NameTimeMethod
Objective response rate (ORR) evaluated by BIRC (Response evaluation in Nerufibromatosis and Schwannomatosis, REiNS criteria)Through study completion, an average of 2 years

ORR is defined as the proportion of patients who have a confirmed complete response or confirmed partial response as determined by ICR per REiNS criteria.

Secondary Outcome Measures
NameTimeMethod
Duration of response (DOR) evaluated by BIRC and the investigator;Through study completion, an average of 2 years

DOR is defined as the time from the date of first documented response (which is subsequently confirmed) until progression by BIRC and the investigator per REiNS criteria or death due to any cause.

Progression free survival (PFS) evaluated by BIRC and the investigator;Through study completion, an average of 2 years

PFS is defined as the time from randomization until date of disease progression by BIRC and investigator per REiNS criteria or death due to any cause.

Change from baseline in pain intensity scoreThrough study completion, an average of 2 years

Difference in mean change from baseline in overall tumor and target PN pain intensity score between Arm A and Arm B as assessed by the 11-point Numerical Rating Scale (NRS-11),which uses the range 0-10,higher scores mean worse outcome.

Time to response (TTR) evaluated by BIRC and the investigator;Through study completion, an average of 2 years

TTR is defined as the time from date of randomization until the date of objective response by BIRC and investigator per REiNS criteria.

Objective response rate (ORR) evaluated by the investigator (REiNS criteria)Through study completion, an average of 2 years

ORR is defined as the proportion of patients who have a confirmed complete response or confirmed partial response as determined by ICR per REiNS criteria.

Clinical benefit rate (CBR)evaluated by BIRC and the investigator;Through study completion, an average of 2 years

CBR is defined as the proportion of patients who have a confirmed complete response or confirmed partial response or stable disease\>48 weeks as determined by BIRC and the investigator per REiNS criteria.

Time to progression (TTP) evaluated by BIRC and the investigator;Through study completion, an average of 2 years

TTP is defined as the time from randomization until date of disease progression by BIRC and investigator per REiNS criteria.

Change from baseline in appearanceThrough study completion, an average of 2 years

Change in appearance from baseline for Arm A versus Arm B as assessed using a sponsor-customized 'appearance evaluation'PRO questionnaire, which is descriptive.

Disease control rate (DCR) evaluated by BIRC and the investigator;Through study completion, an average of 2 years

DCR is defined as the proportion of patients who have a confirmed complete response or confirmed partial response or stable disease as determined by BIRC and the investigator per REiNS criteria.
