Complete Guide,Japan initiates market authorization of weight‐loss drug semaglutide

The journey of semaglutide in Japan has been marked by a series of significant milestones, primarily concerning its approval for both diabetes management and, more recently, for weight loss. This glucagon-like peptide-1 (GLP-1) receptor agonist, developed by Novo Nordisk Pharma, has seen its various formulations gain traction within the Japanese healthcare system.

A Timeline of Approvals and Market Authorization

The semaglutide approval Japan narrative began with its application for type 2 diabetes. Ozempic (semaglutide injection) received its approval in Japan on March 23, 2018, by the Japanese Ministry of Health, Labor and Welfare (MHLW). This was based on the comprehensive SUSTAIN clinical trial program. Subsequently, Rybelsus (oral semaglutide) also secured approval in Japan on June 28, 2020, marking a significant step as the first and only oral semaglutide formulation available. Rybelsus is approved for use in three therapeutic dosages, 3 mg, 7 mg and 14 mg in Japan. An oral formulation of the GLP-1 analog, semaglutide, was approved in Japan in 2020 for treatment of individuals with type 2 diabetes. Research, such as the PIONEER REAL Japan study, has demonstrated the efficacy of oral semaglutide in Japanese patients with type 2 diabetes, showing significant reductions in HbA1c.

More recently, the focus has shifted to the weight-loss indication. In November 2023, semaglutide, under the brand name Wegovy®, was granted regulatory approval for weight management. This development was further solidified when Wegovy® has been marketed since 22 February 2024 by Novo Nordisk Pharma in Japan. The Japan initiates market authorization of weight-loss drug semaglutide process indicates a broader acceptance of semaglutide for obesity treatment. It's noteworthy that Wegovy (semaglutide) is approved by NMPA (China) for long-term weight management, highlighting its global regulatory progress. The Japan initiates market authorization of weight-loss drug semaglutide is happening under universal health coverage, but with stringent prescription restrictions.

Understanding the Regulatory Landscape

Japan's regulatory approval pathway for pharmaceuticals is overseen by the Pharmaceuticals and Medical Devices Agency (PMDA) and the MHLW. The semaglutide approval Japan process involves rigorous evaluation of safety and efficacy data from clinical trials. For instance, the approval of Ozempic® was underpinned by the SUSTAIN trials, and Rybelsus® by the PIONEER trials.

It is important to note that while semaglutide has seen widespread approval, nuances exist in its application. For example, in Japan, the maximum dose of once-weekly (OW) semaglutide is 1.0 mg per week, whereas a higher dose of 2.0 mg per week is approved in other countries. Furthermore, oral semaglutide has not been approved as a first-line drug in Japan, meaning patients often receive other treatments like SGLT2 inhibitors first.

Market Entry and Healthcare Integration

Following regulatory approval, Novo Nordisk Pharma has actively worked on market penetration. Wegovy® officially commenced marketing in Japan on February 22, 2024. A significant development for patient access was the addition of Wegovy (semaglutide) to Japan's national health insurance list on November 24, 2023. This means most patients in Japan will be able to access the weight-loss drug through their health insurance, albeit with potential restrictions. The Sumitomo Pharma and Novo Nordisk Pharma Enter into a Co-Promotion Agreement, further solidifying the market presence of Novo Nordisk Pharma's products in Japan.

Continued Research and Development

The presence of semaglutide in Japan is supported by ongoing research. Studies like "Effectiveness and Safety of Once-Weekly Semaglutide in Japanese Patients with Type 2 Diabetes" and analyses of oral semaglutide efficacy by baseline age in Japanese patients with type 2 diabetes contribute to a deeper understanding of the drug's performance in the local population. Novo Nordisk files for regulatory approval of once-weekly semaglutide in Japan demonstrates their continuous commitment to the Japanese market.
