News Release Detail

PLYMOUTH MEETING, Pa. and DEVON, Pa., Aug. 14, 2023 /PRNewswire/ -- Harmony Biosciences Holdings, Inc. ("Harmony") (Nasdaq: HRMY), a pharmaceutical company dedicated to developing and commercializing innovative therapies for patients with rare neurological diseases, today announced a definitive agreement to acquire Zynerba Pharmaceuticals, Inc. ("Zynerba") (Nasdaq: ZYNE), a leader in innovative pharmaceutically-produced transdermal cannabinoid therapies for orphan neuropsychiatric disorders, including Fragile X syndrome (FXS).

Under the terms of the definitive agreement, Harmony will commence a tender offer to acquire all outstanding shares of Zynerba for a purchase price of $1.1059 per share in cash, or $60 million in the aggregate, plus one non-tradeable contingent value right (CVR) per share, representing the right to receive potential additional payments of up to $140 million in the aggregate, subject to the achievement of certain clinical, regulatory and sales milestones, as described in more detail below.

"This is an important step in Harmony's strategy to build a diversified portfolio of innovative assets to address unmet medical needs and drive our long-term growth. This acquisition affords us the opportunity to advance the development and delivery of a potentially transformative treatment for the symptoms of Fragile X syndrome and other rare neuropsychiatric disorders," said Jeffrey M. Dayno, M.D., President and Chief Executive Officer at Harmony Biosciences. "In addition to the strength of our core business in narcolepsy and our current life cycle management programs, led by idiopathic hypersomnia, we are excited to continue to diversify our portfolio beyond sleep/wake by adding Zynerba's clinical development programs to our pipeline. The team at Zynerba has been dedicated to these programs and we are confident that our combined efforts could have a profound impact on individuals living with rare neuropsychiatric disorders and their families." 

"Harmony's development and commercial expertise, technologies, people and focus on rare neurological diseases are an excellent strategic fit with Zynerba," said Armando Anido, Chairman and Chief Executive Officer of Zynerba. "I am very proud of Zynerba's accomplishments with Zygel™ to date. With Harmony's scale, resources and proven commercial excellence, they are well positioned to potentially bring to market the first pharmaceutical product indicated for the treatment of behavioral symptoms of Fragile X syndrome and to maximize the value of Zygel."

Zynerba's lead asset, Zygel, is the first and only pharmaceutically manufactured, synthetic cannabidiol, a non-euphoric cannabinoid, formulated as a patent-protected permeation-enhanced gel for transdermal delivery through the skin and into the circulatory system. Zygel is manufactured through a synthetic process in a cGMP facility and is not extracted from the cannabis plant. Therefore, it is devoid of THC, which is what causes the euphoric effect of cannabis, and has the potential to be a nonscheduled product if approved. Zygel is currently being evaluated in a pivotal Phase 3 clinical trial for patients living with FXS, known as the RECONNECT Trial. Additionally, Zygel showed positive signals in an open label Phase 2 trial in patients living with 22q11.2 deletion syndrome (22q), called the INSPIRE Trial.

Cannabidiol, the active ingredient in Zygel, has been granted orphan drug designation by the United States Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of FXS and for the treatment of 22q. Additionally, Zygel has received FDA Fast Track designation for the treatment of behavioral symptoms in patients with FXS.

FXS is a rare genetic disorder that affects approximately 80,000 people in the U.S., causing intellectual disabilities and behavioral challenges. Despite considerable progress in medical science, there remains a significant unmet medical need in treating patients living with this debilitating disorder. There are currently no FDA approved therapies to treat FXS.

It is estimated that there are approximately 80,000 people living with 22q in the U.S. Patients with 22q are affected by symptoms related to many organ systems including neuropsychiatric symptoms such as anxiety and behavioral difficulties. There are currently no FDA-approved therapies to treat 22q.

The CVR is payable subject to certain terms and conditions upon achievement of the following milestones:

Clinical Milestones

• Completion of FXS Phase 3 clinical trial: $15 million in the aggregate or approximately $0.2747 per share
• Positive data readout from FXS Phase 3 clinical trial:

$30 million in the aggregate or approximately $0.5494 per share if completed on or before December 31, 2024
$20 million in the aggregate or approximately $0.3663 per share if completed on or before June 30, 2025
$10 million in the aggregate or approximately $0.1831 per share if completed after June 30, 2025

Each CVR is subject to the achievement of the milestone conditions described above, and there can be no assurance whether any such milestones will be achieved or when any payments will be made with respect to any CVR.

The transaction is expected to close by the fourth quarter of 2023, subject to customary closing conditions, including that the holders of at least a majority of the outstanding shares of Zynerba's common stock tender such shares to Harmony in connection with the tender offer. Following the successful closing of the tender offer, Harmony will acquire any shares of Zynerba it does not already own through a second-step merger at the same per share offer price as paid in the tender offer. Zynerba's board of directors unanimously recommends that Zynerba's stockholders tender their shares in the tender offer.

About Fragile X Syndrome
Fragile X syndrome (FXS) is a rare genetic disorder that is the leading known cause of both inherited intellectual disability and autism spectrum disorder, affecting 1 in 3,600 to 4,000 males and 1 in 4,000 to 6,000 females. The disorder negatively affects synaptic function, plasticity and neuronal connections, and results in a spectrum of intellectual disabilities and behavioral symptoms, such as social avoidance and irritability. There are approximately 80,000 people in the U.S. and approximately 121,000 people in the European Union and UK living with FXS. There is a significant unmet medical need in patients living with FXS as there are currently no FDA approved treatments for this disorder.

FXS is caused by a mutation in FMR1, a gene which modulates a number of systems, including the endocannabinoid system, and most critically, codes for a protein called FMRP. The FMR1 mutation manifests as multiple repeats of a DNA segment, known as the CGG triplet repeat, resulting in deficiency or lack of FMRP. FMRP helps regulate the production of other proteins and plays a role in the development of synapses, which are critical for relaying nerve impulses, and in regulating synaptic plasticity. In people with full mutation of the FMR1 gene, the CGG segment is repeated more than 200 times, and in most cases causes the gene to not function. Methylation of the FMR1 gene also plays a role in determining functionality of the gene. In approximately 60% of patients with FXS, who have complete methylation of the FMR1 gene, no FMRP is produced, resulting in dysregulation of the systems modulated by FMRP.

About 22q11.2 Deletion Syndrome
22q11.2 deletion syndrome (22q) is a disorder caused by a small missing piece of the 22^nd chromosome. The deletion occurs near the middle of the chromosome at a location designated q11.2. It is considered a mid-line condition, with physical symptoms including characteristic palate abnormalities, heart defects, immune dysfunction, and esophageal / GI issues, as well as debilitating neuropsychiatric and behavioral symptoms, including anxiety, social withdrawal, ADHD, cognitive impairment and autism spectrum disorder. It is estimated that 22q occurs in one in 4,000 live births, suggesting that there are approximately 80,000 people living with 22q in the U.S. and 129,000 in the European Union and the UK. Patients with 22q deletion syndrome are managed by multidisciplinary care providers, and there are currently no FDA approved treatments for this disorder.
