Zevra Therapeutics Presents Design of Phase 2 Clinical Trial Investigating KP1077 for the Treatment of Idiopathic Hypersomnia (IH) at Beyond Sleepy 2023

Zevra is a corporate sponsor of the Hypersomnia Foundation and Beyond Sleepy Conference

CELEBRATION, Fla., June 03, 2023 (GLOBE NEWSWIRE) -- Zevra Therapeutics, Inc. (NasdaqGS: ZVRA) (Zevra, or the Company, formerly Zevra.), a rare disease therapeutics company, today announced that an oral presentation featuring the Phase 2 clinical trial design evaluating KP1077 as a treatment for idiopathic hypersomnia (IH), a rare neurological sleep disorder, will be presented at the Hypersomnia Foundation’s 2023 Beyond Sleepy Conference being held June 2 - 4, 2023, in Indianapolis, IN, for people living with IH, narcolepsy and Kleine-Levin syndrome and their supporters. Zevra is a corporate sponsor of the Hypersomnia Foundation and the Beyond Sleep program.

“We are proud to sponsor the Hypersomnia Foundation and the Beyond Sleepy program as part of Zevra’s commitment to support the patients and caregivers dealing with rare sleep disorders. We believe the design of the Phase 2 study will allow us to evaluate KP1077’s effect on several unmet needs associated with IH, including excessive daytime sleepiness, extreme difficulty waking, and severe brain fog,” said Christal Mickle, President, interim Chief Executive Officer and Chief Development Officer of Zevra. “We expect to report interim data from the Phase 2 trial exploring the optimal SDX dose range and regimen as early as Q3 2023.”

KP1077 is comprised solely of serdexmethylphenidate (SDX), Zevra’s proprietary prodrug of d-methylphenidate. SDX was recently granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the treatment of IH. Zevra has also opened an IND to study KP1077 for the treatment of narcolepsy.

Details of Zevra’s oral presentation are as follows:

Title:	A Clinical Study with KP1077 in Adults with Idiopathic Hypersomnia
Oral Presentation:	Sunday, June 4, 2023, 10:20 AM – 10:50 AM ET
Speaker:	Rene Braeckman, Ph.D., Sr. Vice President of Clinical Development, Zevra, Orlando, FL USA and Christopher Drake, PhD, FAASM, DBSM, Director of Sleep Research, Henry Ford Health, Detroit, MI
Location:	Fletcher Place

The Company will also attend SLEEP 2023, the 37^th annual meeting of the Associated Professional Sleep Societies (APSS), being held in Indianapolis, IN, June 3-7, 2023, and will host booth number 233.

It is estimated that 37,000 patients are currently diagnosed with IH and seeking treatment in the U.S., although the total population may be much larger due to patients not seeking treatment, undiagnosed or misdiagnosed.

About SDX and KP1077:

Serdexmethylphenidate (SDX) is Zevra’s proprietary prodrug of d-methylphenidate (d-MPH) and the sole active pharmaceutical ingredient (API) in KP1077, Zevra’s lead clinical candidate being developed as a treatment for idiopathic hypersomnia (IH) and narcolepsy. Zevra is currently enrolling a multicenter, dose-optimizing, double-blind, placebo-controlled, randomized-withdrawal Phase 2 clinical trial to evaluate safety and efficacy of KP1077 as a treatment for IH. For more information regarding the Phase 2 trial, visit www.clinicaltrials.gov.

SDX is also the primary API in AZSTARYS®, a once-daily product for the treatment of attention deficit hyperactivity disorder (ADHD) in patients ages six and older being commercialized in the U.S. by Corium, Inc.

KP1077 has been granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the treatment of IH, and the U.S. Drug Enforcement Agency (DEA) has classified SDX, the sole API in KP1077, as a Schedule IV controlled substance based on evidence suggesting SDX has a lower potential for abuse when compared to d-MPH, a Schedule II controlled substance.
