– Delisting of REMS Patent sets path to potentially accelerate final approval by FDA
DUBLIN, Ireland, Nov. 18, 2022 (GLOBE NEWSWIRE) — Avadel Pharmaceuticals plc (Nasdaq: AVDL), a biopharmaceutical company focused on transforming medicines to transform lives, announced today that the United States District Court for the District of Delaware (the “Delaware Court”) ordered Jazz Pharmaceuticals to delist U.S. Patent No. 8731963 (the “REMS Patent”) from the U.S. Food and Drug Administration’s (“FDA”) Orange Book. With this decision, Avadel seeks to accelerate the FDA’s final approval decision for LUMRYZ™, a once-at-bedtime investigational formulation of sodium oxybate for the treatment of cataplexy or excessive daytime sleepiness (EDS) in adults with narcolepsy.
“We are pleased with the court’s decision in favor of delisting the REMS Patent from the FDA’s Orange Book, potentially accelerating a final approval. Upon the delisting of the REMS Patent, we are prepared to work collaboratively with the FDA to move to a final approval decision for LUMRYZ,” said Greg Divis, Chief Executive Officer at Avadel Pharmaceuticals. “We are fully committed to bringing LUMRYZ to all eligible people with narcolepsy and look forward to providing updates on our progress.”
On July 18, 2022, LUMRYZ received tentative approval from the FDA, with potential final approval pending disposition of the REMS Patent. On October 25, 2022, a Markman hearing was held in which Avadel renewed its request for expedited consideration of its pending motion to have the REMS Patent delisted from FDA’s Orange Book. The Delaware Court granted that request on October 28th and held a hearing on that motion on November 15, 2022. Earlier today, the Delaware Court issued its written opinion ordering Jazz to request delisting of the REMS Patent. With the issuance of this ruling, Avadel intends to seek final FDA approval for LUMRYZ upon removal of the REMS Patent from the FDA’s Orange Book.
LUMRYZ is an investigational formulation of sodium oxybate leveraging our proprietary drug delivery technology and designed to be taken once-at bedtime for the treatment of cataplexy or excessive daytime sleepiness (EDS) in adults with narcolepsy.
In March 2020, Avadel completed the REST-ON study, a randomized, double-blind, placebo-controlled, pivotal Phase 3 trial, to assess the efficacy and safety of LUMRYZ in patients with narcolepsy. Among the three co-primary endpoints, LUMRYZ demonstrated statistically significant and clinically meaningful results in EDS, the clinician’s overall assessment of the patient’s functioning, and reduction in cataplexy attacks, for all three evaluated does when compared to placebo.
In January 2018, the U.S. Food and Drug Administration (FDA) granted LUMRYZ Orphan Drug Designation for the treatment of narcolepsy based on the plausible hypothesis that LUMRYZ may be safer than the twice-nightly formulation of sodium oxybate already approved by the FDA due to the ramifications associated with dosing regimen of that product.
On July 18, 2022, the FDA tentatively approved the LUMRYZ NDA for the treatment of cataplexy or EDS in adults with narcolepsy.
Avadel is currently evaluating the long-term safety and tolerability of LUMRYZ in the open-label RESTORE clinical study. For more information, visit: www.restore-narcolepsy-study.com.
