In which countries is Azstarys approved?

Introduction to Azstarys
Azstarys is an innovative therapeutic agent developed as a first-of-its-kind treatment for attention-deficit/hyperactivity disorder (ADHD). This medication distinguishes itself by featuring a dual-mechanism formulation that combines an extended-release prodrug with an immediate-release component, offering both rapid onset and sustained symptom control. Its novel design targets a well-known challenge in the treatment landscape of ADHD, where maintaining consistent clinical benefit throughout the day is crucial for patients with this condition. In addition to its therapeutic role in ADHD, recent developments in clinical research and drug lifecycle management have positioned Azstarys as a promising candidate across various demographics, further reinforcing its clinical and commercial significance.

Drug Composition and Mechanism
Azstarys is a combination product that leverages the pharmacological advantages of two distinct components—a prodrug known as serdexmethylphenidate (SDX) and an immediate-release formulation of d-methylphenidate (d-MPH). The prodrug (SDX) is designed to undergo conversion in the body, gradually releasing the active ingredient to provide extended symptom control. Meanwhile, the immediate-release d-MPH component works swiftly to offer an initial therapeutic effect soon after administration. This dual-action mechanism provides a balanced treatment effect, ensuring a rapid onset of action alongside prolonged efficacy, thereby addressing both early and late-day symptomatology in ADHD patients. The rationale behind combining these two forms is to mitigate the “wearing-off” challenge observed with some monotherapy stimulant agents, which can significantly enhance both the clinical outcomes and the overall tolerability profile of the medication.

Indications and Usage
Currently, Azstarys is primarily indicated for the treatment of attention-deficit/hyperactivity disorder (ADHD) in patients aged six years and older. ADHD is a neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity, which can adversely affect academic performance, occupational success, and social interactions. By targeting core ADHD symptoms, Azstarys offers physicians an option that not only rapidly alleviates symptoms but also maintains a consistent therapeutic effect throughout the day. While its primary indication is for ADHD treatment, ongoing research as well as additional regulatory submissions may broaden the spectrum of its clinical use in the future. Some exploratory studies and regulatory reviews have even considered other indications, such as idiopathic hypersomnia, yet the pivotal clinical development and approval trajectory of Azstarys remain firmly rooted in its application for ADHD.

Regulatory Approval Process
The journey from drug development to regulatory approval is rigorous and involves multiple stages of preclinical and clinical evaluation. Azstarys has undergone an extensive evaluation process that includes well-designed clinical trials—spanning Phase I through Phase III—to establish its safety, efficacy, and tolerability. The path to regulatory approval is not merely a scientific process but also a multi-stakeholder collaboration involving drug manufacturers, regulatory agencies, clinical investigators, and patient advocacy groups. Such a journey ensures that the final product meets high standards of quality and is aligned with the public health needs of the target population.

Overview of Drug Approval
The approval process for Azstarys encompassed several critical milestones. Its clinical development program featured robust Phase III trials that demonstrated statistically significant improvements in key performance indices like the ADHD Rating Scale (ADHD-RS-5) and measures of performance such as the PERMP-A (Permanent Product Measure of Performance) rating scale. After establishing the favorable safety and efficacy profile, the manufacturer submitted a New Drug Application (NDA). On May 7, 2021, the U.S. Food and Drug Administration (FDA) granted marketing approval for Azstarys, marking a significant achievement in its clinical development lifecycle. This approval process by the leading North American regulatory authority followed comprehensive reviews of the clinical data, pharmacological information, and manufacturing processes that ensured the product’s compliance with stringent quality and safety standards. The established approval timeline underscores the robust evidence base and the systematic regulatory approach that underpins this milestone.

Key Regulatory Bodies
The primary regulatory body involved in the approval of Azstarys in its initial market launch is the U.S. Food and Drug Administration (FDA). Specifically, the FDA’s Center for Drug Evaluation and Research (CDER) evaluated the submission from the manufacturer and concluded that Azstarys met the necessary risk–benefit profile for its intended use. This agency has a long-standing reputation for its rigorous review standards and transparency, ensuring that medications launched in the United States are both safe and effective for public use.
In addition to the FDA, the landscape of global regulatory affairs often involves multiple regional authorities—for example, the European Medicines Agency (EMA) in Europe and various national regulatory bodies across Asia. Although the primary documented regulatory approval for Azstarys is via the FDA in the United States, there are strategic licensing arrangements and deals that suggest an expansion of regulatory submissions in other jurisdictions, such as Greater China. Such licensing arrangements are crucial for paving the way for eventual approvals in additional markets. These strategic partnerships typically involve local companies that have intimate knowledge of their country’s or region’s regulatory frameworks, thereby facilitating smoother submissions and eventual market authorizations.

Global Approval Status of Azstarys
Given its innovative profile and promising clinical efficacy, Azstarys has attracted worldwide interest. However, actual regulatory approval and commercial launch in any given country are contingent upon the respective regulatory agency’s review process, local market dynamics, and the fulfillment of necessary documentation and clinical data submissions. The present status of global approval for Azstarys is primarily anchored by its approval in the United States, while other regions are in varied stages of regulatory development and market preparation.

Countries with Approval
Based on the most reliable and structured data provided—particularly those results originating from the synapse source—Azstarys has been formally approved by the U.S. Food and Drug Administration (FDA) for marketing in the United States. The FDA approved the drug on May 7, 2021, following a comprehensive review of its clinical efficacy, safety profile, and manufacturing standards. This approval confirms that Azstarys meets the rigorous standards required by the FDA, making it available to clinicians and patients across the United States.
Furthermore, additional licensing and marketing rights agreements further consolidate Azstarys’s presence in the U.S. market. For example, an agreement involving Zevra Therapeutics, Inc. and Corium International, Inc. outlines plans for the marketing and distribution of Azstarys in the United States. These partnerships not only ensure that the drug is commercialized effectively but also reinforce the commitment to meeting both clinical and commercial expectations in the U.S.
It is important to note that while the explicit regulatory approval is the FDA’s decision, the available evidence consistently identifies the U.S. as the only country where Azstarys has received formal marketing authorization as of now.

Countries Pending Approval
While Azstarys enjoys a robust approval status in the United States, the landscape in other regions is more complex. In Greater China, there is significant interest in bringing Azstarys to market. Notably, an exclusive license agreement was signed between Commave Therapeutics SA (the manufacturer) and Shanghai Ark Biopharmaceutical Co., Ltd., exclusively for the rights to Azstarys across regions including China. However, this agreement indicates that the drug is in the process of being prepared for regulatory submission and potential approval within China, rather than a confirmation that it is already approved. The exclusive license suggests that once local regulatory agencies in China have reviewed and accepted the dossier under their established guidelines, Azstarys will be available as an approved treatment option in that market.
Similarly, while there have been discussions and strategic initiatives related to the European market, there is as yet no conclusive evidence from structured synapse data confirming an EMA approval for Azstarys. Multiple clinical trial developments and drug development phase references—such as those associated with Commave Therapeutics SA and Catalent Greenville, Inc.—allude to the possibility that future submissions to the EMA or other European national authorities may occur. However, these remain in developmental pipelines and regulatory submission phases, rather than in the domain of formal, documented approvals.
In summary, aside from the United States, other markets including China and potentially European countries appear to be on the horizon for Azstarys’s regulatory approvals. Nevertheless, from the standpoints of structured and reliable data—especially from synapse—it is only in the United States that formal regulatory approval has been documented so far.
