简要总结
A global study to demonstrate the effectiveness of selumetinib in participants with NF1 who have symptomatic, inoperable plexiform neurofibromas.
详细描述
This is a randomized, double-blind, placebo-controlled, 2 arm multicentre, global Phase III study to assess the efficacy and safety of selumetinib compared with placebo in adult participants with NF1 who have symptomatic, inoperable PN.

结局指标
主要结局
Confirmed Partial and Complete Response Rate (ORR) by End of Cycle 16 Using Volumetric MRI Analysis as Determined by ICR (Per REiNS Criteria) in Participants With NF1 Who Have Symptomatic, Inoperable PN.
时间窗: From first dose up until progression (if it occurs prior to the end of Cycle 16), or the last evaluable assessment up to and including the end of Cycle 16, excluding MRI during prolonged study intervention interruption (defined as interruption >= 28 days)
Objective response rate is defined as the proportion of participants who have a confirmed CR (defined as disappearance of the target PN, confirmed by a consecutive scan within 3 to 6 months after the first response) or confirmed PR (defined as a target PN volume decrease ≥ 20%, compared to baseline, confirmed by a consecutive scan within 3 to 6 months after the first response) by end of Cycle 16 as determined by ICR per REiNS criteria. Increase in the volume of the target PN by 20% or more compared to baseline or the time of best response after documenting a PR is considered as PD.
次要结局
- (First Key Secondary) The Difference of the Means in the Change From Baseline in PAINS-pNF Chronic Target PN Pain Intensity Score at Cycle 12 Between Selumetinib and Placebo, Primary Analysis(Baseline and end of cycle 12 of study intervention)
- (First Key Secondary) The Difference of the Means in the Change From Baseline in PAINS-pNF Chronic Target PN Pain Intensity Score at Cycle 12 Between Selumetinib and Placebo, Supplemental Analysis(Baseline and end of cycle 12 of study intervention)
- (Second Key Secondary Endpoint) The Difference of the Means in the Change From Baseline in PlexiQoL Total Score at Cycle 12(Baseline and end of Cycle 12 of study intervention)
