Study Endpoints

Primary Endpoints

Subjects With Treatment-Emergent Adverse Events (TEAEs)
Up to 12 months

TEAEs will be assessed starting following the first dose of study drug, and ending with the Follow-Up Visit or Early Termination Visit.

Change From Baseline in Swanson, Kotkin, Agler, M-Flynn, and Pelham (SKAMP) Combined Scores
Average of all time points during the full laboratory classroom day, which occurred on Day 7 (Day 28 of the overall study) of the Treatment Phase

The SKAMP scale is a validated rating of subjective impairment of classroom behaviors in children with ADHD. It comprises 13 items (grouped under the subcategories of attention, deportment, quality of work, and compliance) on which subjects are rated according to a 7-point scale (0 = normal to 6 = maximal impairment) by trained study personnel (Swanson 1998). The SKAMP-C score was obtained by summing the rating values for each of the 13 items (range: 0-78), with higher scores indicating greater impairment.

Frequently asked questions about KP415

What is KP415?

KP415 is an investigational small molecule developed by Zevra Therapeutics, Inc. (ticker ZVRA) for the treatment of ADHD. It is an oral capsule that has been studied in Phase 3 clinical trials in children 6 to 12 years of age. KP415 is not yet approved and remains in clinical development.

What is KP415 used for in ADHD?

KP415 is being developed for the treatment of attention-deficit/hyperactivity disorder (ADHD) in children. Two completed Phase 3 trials enrolled a total of 437 participants aged 6 to 12 years in the United States. The program includes both a classroom study and an open-label safety study.

Who makes KP415?

KP415 is developed by Zevra Therapeutics, Inc., which trades under the ticker ZVRA. The company is the sponsor of the KP415 clinical program in ADHD, including the Phase 3 classroom and open-label safety studies conducted in the United States.

What phase is KP415 in?

KP415 is in Phase 3 clinical development for ADHD. Both of its Phase 3 trials have been completed, and no trials are currently active. The program has not been approved by the FDA, so KP415 remains an investigational product rather than an approved therapy.

What clinical trials is KP415 in?

KP415 has been studied in two completed Phase 3 trials: NCT03460652, an open-label safety study in children 6 to 12 years of age with ADHD that enrolled 282 participants, and NCT03292952, a classroom study in children 6 to 12 years of age with ADHD that enrolled 155 participants. Both were conducted in the United States.

Is KP415 the same as KP415 oral capsule?

Yes. KP415 oral capsule is another name for KP415, the investigational ADHD therapy developed by Zevra Therapeutics, Inc. (ZVRA). Both names refer to the same small molecule product candidate studied in the Phase 3 classroom and open-label safety trials in children aged 6 to 12 years.
