ALKS-2680

DUBLIN, April 1, 2025 /PRNewswire/ -- Alkermes plc (Nasdaq: ALKS) today announced the initiation of Vibrance-3, a phase 2 clinical study evaluating the safety and efficacy of ALKS 2680 compared to placebo in adults with idiopathic hypersomnia (IH). ALKS 2680 is the company's novel, investigational, oral, selective orexin 2 receptor (OX2R) agonist in development as a once-daily treatment for narcolepsy type 1, narcolepsy type 2 and IH – chronic, neurological disorders characterized by excessive daytime sleepiness. "The initiation of Vibrance-3 represents an important step forward for the ALKS 2680 development program as we seek to advance a potential new treatment option for people living with idiopathic hypersomnia. There remains high unmet need for the idiopathic hypersomnia community, as evidenced by a recent survey conducted by the Sleep Consortium1 in which more than 90% of patients surveyed indicated that IH symptoms had a moderate to high impact on their life," said Craig Hopkinson, M.D., Chief Medical Officer and Executive Vice President, Research & Development at Alkermes. "The Vibrance-3 phase 2 study builds on encouraging data from our phase 1b, proof-of-concept study of ALKS 2680 in patients with IH, and we look forward to further characterizing its safety and efficacy profile in this patient population." Vibrance-3 is a phase 2, randomized, double-blind, dose-range-finding, placebo-controlled study evaluating the safety and efficacy of ALKS 2680 in adults with IH. Participants will be randomized to receive one of three doses of ALKS 2680 (10 mg, 14 mg or 18 mg) or placebo to be taken once-daily for eight weeks. The primary endpoint will assess, by dose level, whether participants taking ALKS 2680 experience a greater decrease in sleepiness compared to participants taking placebo alone, as measured by the change in Epworth Sleepiness Scale (ESS) score. Secondary endpoints include change in Idiopathic Hypersomnia Severity Scale (IHSS) score and incidence of adverse events. The study is expected to enroll approximately 96 patients with IH across sites in the U.S., Australia and Europe. Participants who complete the study will be eligible to continue in a long-term, open-label, safety study (NCT06767683). More information can be found at (identifier: NCT06843590) and (for U.S. audiences only). Vibrance-1 and Vibrance-2, phase 2 studies evaluating the safety and efficacy of ALKS 2680 in adults with narcolepsy type 1 (NCT06358950) and narcolepsy type 2 (NCT06555783), respectively, are currently ongoing. About ALKS 2680 ALKS 2680 is a novel, investigational, oral, selective orexin 2 receptor (OX2R) agonist in development as a once-daily treatment for narcolepsy type 1 (NT1), narcolepsy type 2 (NT2) and idiopathic hypersomnia (IH). Orexin, a neuropeptide produced in the lateral hypothalamus, is considered to be the master regulator of wakefulness due to its activation of multiple, downstream wake-promoting pathways that project widely throughout the brain.2 Targeting the orexin system may address excessive daytime sleepiness across hypersomnolence disorders, whether or not deficient orexin signaling is the underlying cause of disease.3 Once-daily oral administration of ALKS 2680 was previously evaluated in a phase 1 study in healthy volunteers and patients with NT1, NT2 and IH, and is currently being evaluated in the phase 2 Vibrance-1, Vibrance-2 and Vibrance-3 studies in patients with NT1, NT2 and IH, respectively. About Idiopathic Hypersomnia Idiopathic hypersomnia (IH) is a rare, chronic, neurological sleep disorder characterized by excessive daytime sleepiness despite normal sleep durations.4,5 Additional common symptoms can include severe sleep inertia (individuals may feel groggy or disoriented for prolonged periods after waking up), unrefreshing naps, fatigue and cognitive dysfunction.6,7 The underlying neuropathology of idiopathic hypersomnia is unknown.4 IH affects an estimated 40,000 people in America.8 About Alkermes plc Alkermes plc is a global biopharmaceutical company that seeks to develop innovative medicines in the field of neuroscience. The company has a portfolio of proprietary commercial products for the treatment of alcohol dependence, opioid dependence, schizophrenia and bipolar I disorder, and a pipeline of clinical and preclinical candidates in development for neurological disorders, including narcolepsy and idiopathic hypersomnia.

Non-GAAP Financial Measures This press release includes information about certain financial measures that are not prepared in accordance with generally accepted accounting principles in the U.S. (GAAP), including non-GAAP net income, EBITDA and Adjusted EBITDA. These non-GAAP measures are not based on any standardized methodology prescribed by GAAP and are not necessarily comparable to similar measures presented by other companies. Non-GAAP net income adjusts for certain one-time and non-cash charges by excluding from GAAP results: share-based compensation expense; amortization; depreciation; non-cash net interest expense; change in the fair value of contingent consideration; certain other one-time or non-cash items; and the income tax effect of these reconciling items. EBITDA represents earnings before interest, tax, depreciation and amortization. Adjusted EBITDA excludes share-based compensation expense in addition to the components of EBITDA from earnings. The company's management and board of directors utilize these non-GAAP financial measures to evaluate the company's performance. The company provides these non-GAAP financial measures of the company's performance to investors because management believes that these non-GAAP financial measures, when viewed with the company's results under GAAP and the accompanying reconciliations, are useful in identifying underlying trends in ongoing operations. However, non-GAAP net income, EBITDA and Adjusted EBITDA are not measures of financial performance under GAAP and, accordingly, should not be considered as alternatives to GAAP measures as indicators of operating performance. Further, non-GAAP net income, EBITDA and Adjusted EBITDA should not be considered measures of the company's liquidity. A reconciliation of GAAP to non-GAAP financial measures has been provided in the tables included in this press release.

The company cautions that forward-looking statements are inherently uncertain. The forward-looking statements are neither promises nor guarantees and they are necessarily subject to a high degree of uncertainty and risk.

These risks and uncertainties include, among others: whether the company is able to achieve its financial expectations, including those related to profitability; clinical development activities may not be completed on time or at all; the results of the company's development activities may not be positive, or predictive of final results from such activities, results of future development activities or real-world results; the unfavorable outcome of arbitration, litigation, or other proceedings or disputes related to the company's products or products using the company's proprietary technologies; the U.S. Food and Drug Administration (FDA) or regulatory authorities outside the U.S. may make adverse decisions regarding the company's products; the company and its licensees may not be able to continue to successfully commercialize their products or support revenue growth from such products; there may be a reduction in payment rate or reimbursement for the company's products or an increase in the company's financial obligations to government payers; the company's products may prove difficult to manufacture, be precluded from commercialization by the proprietary rights of third parties, or have unintended side effects, adverse reactions or incidents of misuse; and those risks and uncertainties described under the heading "Risk Factors" in the company's most recent Annual Report on Form 10-K and in subsequent filings made by the company with the U.S. Securities and Exchange Commission (SEC), which are available on the SEC's website at .
