Clinical trial Recruiting at 1 site Phase 1 Interventional Ages 18 to 64

Testing Lu AH69593 for safety and tolerance in healthy adults and people with narcolepsy

Official title: Interventional, Randomized, Double-blind, Sequential-group, Placebo-controlled, Single- and Multiple-ascending-dose Trial Investigating Safety, Tolerability, and Pharmacokinetics of Lu AH69593 in Healthy Participants, Including Open-label Cohorts to Explore Pharmacodynamic Properties in Participants With Narcolepsy, and Food Effect in Healthy Participants

Run by H. Lundbeck A/S · NCT07613710 · Data updated 2026-11-12

This study tests whether Lu AH69593 is safe and well tolerated in adults, including those with narcolepsy, and looks at how the body processes the drug with and without food.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–55 (or 64 for Part C) with BMI within specified ranges, a normal circadian rhythm, and stable vital signs, including those with narcolepsy or healthy volunteers as defined by Part A-D criteria.

Probably not a fit

Participants outside the BMI, age, or circadian rhythm criteria or those without narcolepsy may not experience direct benefit from the drug.

What this trial studies

This phase 1 interventional trial evaluates the safety and tolerability of Lu AH69593 in adults who are healthy or have narcolepsy. It also examines pharmacokinetics, comparing drug processing with and without food. The study includes multiple parts with specific inclusion criteria such as age ranges, BMI ranges, resting heart rate, and circadian rhythm considerations. Participants may receive Lu AH69593 or placebo, and enrollment is conducted at several clinical sites in Finland under lead sponsor H. Lundbeck A/S. Outcomes focus on safety signals, tolerability, and how food intake affects drug disposition.

Why it matters

Potential benefit: If successful, the study could establish a safe starting profile for Lu AH69593 and guide dosing strategies for future narcolepsy trials.

How similar studies have gone: Phase 1 trials of similar compounds often establish safety and pharmacokinetics; this study follows that established approach but the specific compound is novel in this context.

* The participant has worked shifts, including night duty, or has travelled across \>3 time zones \<2 weeks prior to the first dose of IMP.
* The participant trains/exercises intensively, for example, for a marathon or triathlon, or at a competitive level.

Specifically for participants in trial Part A, B and D:

* The participant has had a clinically significant illness from which he/she recovered \<4 weeks prior to the first dose of IMP.

Specifically for Participants in trial Part B and C:

* The participant is at significant risk of suicide based on medical history, mental status, investigator judgement, or the C-SSRS answer of 'yes' to suicidal ideation question 4 or 5 or 'yes' to suicidal behaviour, within the last 6 months on the C-SSRS at the Screening Visit or 'Since last visit' at the Baseline Visit Day -1.

Specifically for participants in trial Part C:

* The participant has any other disorder for which the treatment takes priority over treatment of narcolepsy or is likely to interfere with trial treatment or impair treatment compliance.
* The participant has a current medical disorder, other than NT1, associated with excessive daytime sleepiness (EDS).
