a eight-week study of nls-2 (mazindol extended release) in participants with narcolepsy type 1

Conditions: Narcolepsy Type 1; Narcolepsy With Cataplexy

Summary: the goal of this clinical trial is to see how nls-2 (mazindol extended-release) works on symptoms of narcolepsy, including cataplexy and excessive daytime sleepiness. approximately 48 participants will take part in the study across the united states. the study treatment (nls-2 or placebo) will be administered for 8 weeks. after this treatment period, the participant may have the option to participate in a separate long-term extension study during which all participants will be treated with nls-2.

this is a phase 3, double-blind, placebo-controlled, multicenter, randomized, parallel-group clinical trial. the primary goal of this study is to assess the efficacy and safety of nls-2 (mazindol extended-release) tablets in treating narcolepsy type 1. the trial aims to determine the effects of nls-2 on the improvement of narcolepsy symptoms, including cataplexy frequency and excessive daytime sleepiness. participants in this trial will receive either nls-2 or a placebo for 8 weeks. the treatment assignment will be concealed from both the participant and the investigator throughout the trial (unless there is an urgent medical need). approximately 48 patients will be enrolled at multiple clinical sites across the united states. following the completion of the trial, participants may be given the option to enroll in a separate long-term extension trial where all participants will receive nls-2 treatment.
