About this trial
This is a Multi-center, Open-label, Single-arm Phase II Study to Evaluate the Efficacy and Safety of HL-085 in the treatment of Adult Participants with Neurofibromatosis Type 1 (NF1) and Inoperable Plexiform Neurofibromas(PN)

This trial does not accept healthy volunteersQualifiers
Age: patients must be ≥18 years of age at the time of study entry.
Patients must have a measurable lesion, defined as at least 3 cm in length, amenable to MRI for efficacy assessment.
Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.
Patients are able to understand and voluntarily sign a written informed consent form.
Disqualifiers
Patients who are unable to undergo MRI scans (prosthesis, prosthesis, braces, etc.) or patients with lesions that cannot be evaluated by MRI.
Patients do not have adequate organ function.
Patients who are unable to take drugs orally, have difficulty swallowing or anything that may lead to inadequate drug absorption.
Prior treatment with MEK 1/2 inhibitors.

Treatments tested in this trial
HL-085
DrugIIa: HL-085 capsule 9mg administered orally twice daily in a continuous 21-day treatment cycle. If required, dosing schedule can be adjusted to 12mg BID, 6mg BID, or other dosage regimens. IIb: HL-085 at the recommended dose or dosage regimen.
Treatment groups
Trial outcomes
Primary outcomes
Objective Response Rate (ORR)
To assess the efficacy of HL-085 on the tumor volume (plexiform neurofibromas) using volumetric MRI per REiNS criteria. ORR is defined as the percentage of patients who have achieved a confirmed Partial Responses (PR) or Complete Responses (CR).
Secondary outcomes
Disease Control Rate(DCR)
Defined as the percentage of patients who have achieved a confirmed response of CR or PR or SD
Duration of Overall Response(DOR)
Defined as the time from first achieved CR or PR to disease progression
Progression Free survival (PFS)
Defined as the time from first dosing (C1D1) to date of first observed progression or death from any cause (whichever comes first)
