Study Summary

This trial aims to assess the safety, effectiveness, and how the drug is processed and behaves in the body of participants with Narcolepsy Type 1. The study will be in two parts, with

Who is the study for?
This trial is for individuals with Narcolepsy Type 1 (NT1), who have had a valid sleep study in the last 5 years and been diagnosed with NT1 for at least 6 months. They must sleep over 6 hours on most nights and be positive for a specific genetic marker (HLA-DQB1*06:02). Participants should also have a history of cataplexy before starting any related medications.Check my eligibility
What is being tested?
The trial is testing MK-6552, which could potentially treat NT1. The first part checks how safe it is and how the body processes different doses in one day. The second part looks at how well it works after taking it once or multiple times across several days. Some participants will receive a placebo instead to compare results.See study design
What are the potential side effects?
While the side effects are not detailed here, common ones may include reactions where the drug enters the body, changes in alertness, stomach issues, or headaches. Side effects can vary widely from person to person.

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: MK-6552Experimental Treatment1 Intervention
In Part 1, participants will receive single oral doses of MK-6552 in ascending fashion approximately 6 hours apart for a single day, based on safety and tolerability of the previous dose. In Part 2, participants will receive multiple days of MK-6552 dosing (7 consecutive days) at the highest safe and well tolerated MK-6552 dose determined on an individual basis from Part 1.
Group II: PlaceboPlacebo Group1 Intervention
In Part 2, participants will receive multiple days of placebo dosing (7 consecutive days).

Answered by AI

Are individuals above the age of 35 eligible to participate in this clinical trial?

"Eligible participants for this study must be over 18 years of age but under the age of 55."

Answered by AI

What is the primary goal of conducting this scientific study?

"The primary aim of this clinical research, to be assessed over an approximate duration of up to 7 weeks, is the number of participants discontinuing the study intervention due to adverse events (AE). Secondary endpoints include Concentration of MK-6522 at 6 Hours Postdose (C6h), which involves collecting blood samples at specific intervals for C6h determination. Additionally, Apparent Oral Clearance (CL/F) of MK-6552 will be evaluated by analyzing blood samples for CL/F calculation. Another secondary outcome is Concentration of MK-6522 at 18 Hours Postdose (C18h), where blood samples"

Answered by AI

Has MK-6552 received approval from the FDA?

"According to our assessment at Power, the safety rating for MK-6552 is a 1 on a scale of 1 to 3. This reflects the early Phase 1 nature of the trial and limited available data supporting its safety and efficacy."
