A Trial of TAK-861 for the Treatment of Narcolepsy With Cataplexy

The main aim of this study is to assess how effective TAK-861 is for treating narcolepsy type 1 and if this effect is maintained over time. Participants will take TAK-861 for a few months and if they meet certain criteria, they will be randomly assigned (by chance, like flipping a coin) to continue taking TAK-861 or take placebo (fake medicine) for up to 4 weeks to see if their narcolepsy symptoms return.

Ofatumumab in Treatment-Refractory¬ Narcolepsy Type 1

The goal of this clinical trial is to learn if ofatumumab works to treat drug-Refractory¬ Narcolepsy Type 1. It will also learn about the safety of ofatumumab. The main questions it aims to answer are: * Does ofatumumab could improve persistent or chronic NT1 who had insufficient responses to multiple prior treatment regimens or declined conventional medications? * The safety -What medical problems do participants have when taking ofatumumab? Researchers will compare Epworth Sleepiness Scale and cataplexy frequency before and after ofatumumab treatment to see if ofatumumab works to treat drug-Refractory¬ Narcolepsy Type 1. Participants will: * Take one dose of ofatumumab and monitoring one day for the injection-related reactions * Visit the clinic at one month after ofatumumab for checkups and tests * Keep a diary of their symptoms

A Phase 1, First-in-human Study of VX-433

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of VX-433 following single and multiple ascending doses, as well as to assess the effect of VX-433 on the PK of midazolam, bupropion, and hydroxybupropion.
