简要总结
This is an investigator-initiated, exploratory, multicenter, open-label, single-arm clinical trial and a substudy of the Platform Research for Innovative Medicines in NF2-SWN (PRIME-NF2). The study aims to evaluate the safety, tolerability, and preliminary efficacy of luvometinib in combination with serplulimab in patients with NF2-related schwannomatosis (NF2-SWN) with progressive tumors.
详细描述
NF2-related schwannomatosis (NF2-SWN) is a rare autosomal dominant disorder characterized by multiple central nervous system tumors, most commonly vestibular schwannomas and meningiomas. Although current treatments such as surgery and radiotherapy can provide disease control, they are not curative and are associated with cumulative neurological morbidity and potential risk of secondary malignancies. There remains a significant unmet need for effective systemic therapies.
This investigator-initiated study is conducted as a substudy within the Platform Research for Innovative Medicines in NF2-SWN (PRIME-NF2). The trial evaluates luvometinib in combination with serplulimab in patients with progressive NF2-SWN.
Luvometinib (FCN-159) is a selective MEK1/2 inhibitor with antitumor activity in NF1-associated tumors. Serplulimab (HLX10) is an anti-PD-1 monoclonal antibody approved for multiple solid tumors. Preclinical evidence suggests that MEK inhibition may enhance tumor immunogenicity and synergize with immune checkpoint blockade.
The study aims to assess the safety, tolerability, and preliminary efficacy of this combination in NF2-SWN.

结局指标
主要结局
Objective Response Rate (ORR) or Hearing Response Rate (HRR)
时间窗: 12 months
Vestibular schwannoma: HRR is defined as WRS improvement exceeding the 95% critical difference from baseline; if baseline WRS is \<20%, HRR is defined as a PTA decrease of at least 10 dB. Meningioma: ORR is defined as at least a 20% reduction in target tumor volume from baseline.
次要结局
- Incidence of Adverse Events(From first dose through 30 days after last dose (up to 12 months))
- Maximum Severity Grade of Adverse Events(From first dose through 30 days after last dose (up to 12 months))
- Incidence of Serious Adverse Events(From first dose through 30 days after last dose (up to 12 months))
- Incidence of Dose Modifications(From first dose through 30 days after last dose (up to 12 months))
- Incidence of Treatment Interruptions(From first dose through 30 days after last dose.)
- Incidence of Treatment Discontinuations(From first dose through 30 days after last dose.)
