Life sciences specialists from Tilleke & Gibbins have updated the firm’s guide to pharmaceutical data exclusivity regulations and practices in Southeast Asia. This guide contains quick-reference information on the availability of data exclusivity protections and limitations in Cambodia, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam. Developing and launching a new drug on a commercial scale requires an enormous amount of time and investment in research and development (R&D), including pre-clinical testing and clinical trials. When considering the aggregate amount of drug development costs, it is important to recognize that this includes not only the investment in developing new drugs that get approved by a government food and drug regulator and are successfully brought to market, but also the R&D expenditures on a large number of potential pharmaceutical compounds and products that never actually make it to market. In particular, considerable investment is required in order to conduct and produce clinical trial data—to prove safety, efficacy and effectiveness of a new drug—that would warrant marketing approval by the regulatory authority. Such data is proprietary in nature and highly valuable for a research-based pharmaceutical company that develops an original drug. On the other hand, patent law typically confers generic drug manufacturers with the ability to engage in various preparatory activities with a view to obtaining marketing approval for a generic product before the patent for the original drug expires (commonly known as a “Bolar provision”). Since a generic drug maker may submit an application for marketing approval of a generic product before the relevant patent expires, the extent to which the drug originator’s data submitted to the regulatory authority is protected—or in other words, the extent to which the generic company may rely on the drug originator’s previously filed data, which underpins the safety and efficacy of the drug, to support

On June 16, 2025, the National Assembly of Vietnam adopted Law No. 75/2025/QH15 amending and supplementing a number of articles of the 2012 Advertising Law, with an effective date of January 1, 2026. The amended Advertising Law was enacted to further refine the legal framework for advertising activities in the modern era. Online Advertising Under the amended Advertising Law, “online advertising” is defined to encompass not only advertising on electronic newspapers and electronic information pages (as provided under the 2012 Advertising Law) but also advertising on other electronic venues, including social media, online applications, and digital platforms with internet connection. The amended Advertising Law also imposes new requirements for online advertising, including: Identification signs: Advertisements must have clear identifiable signs in numbers, letters, symbols, images, or sounds to distinguish them from non-advertising content. Control features: For advertisements not in fixed areas, there must be easily recognizable features and icons that allow recipients to turn off the advertisement, notify the service provider of violating advertising content, and refuse to view inappropriate advertising content. Linked content: Content in the links embedded in advertisements must comply with the law. Advertising service providers and publishers must have measures to check and monitor the linked content. Advertising on social media: Organizations and enterprises providing social media services must offer users features to distinguish advertising content from other content. Signage for sponsored content: When advertising, users of social media services must use signs to differentiate advertising or sponsored content from other content they provide. In response to the above requirements for online advertising, the amended Advertising Law sets out obligations of advertisers, advertising service providers, advertising publishers, and advertising conveyors in relation to online advertising. Among these, it is notably the responsibility of individuals and organizations engaging in online advertising to prevent and remove violating

On July 3, 2025, Vietnam’s Ministry of Health (MOH) issued Circular No. 34/2025/TT-BYT amending some articles of Circular No. 06/2011/TT-BYT on the management of cosmetics products (Circular 34), which provides the current regulations on the product notification process for cosmetics (cosmetic notification). Circular 34 will come into effect on August 18, 2025. Changes to Cosmetic Notification Some of the key stipulations of Circular 34 are outlined below. Addition of submission route for notification Circular 34 officially adds online submission via the National Public Service Portal as an accepted type of cosmetic notification, in addition to direct submission and submission via post. Clearer regulations on preparing cosmetic notification form Circular 34 provides clarification on the signing requirements for cosmetic notification forms. For online submissions, both e-signatures and digital signatures are accepted. For offline submissions, the circular explicitly states that stamped/generated signatures are not acceptable. There are no substantive changes to existing requirements regarding grouping of products in a single declaration, ingredient listing, or language used in the notification form. Circular 34 only introduces formatting adjustments to these provisions. Updated administrative procedures Circular 34 updates requirements on digital procedures and authentication for online submission with references to new government decrees. In addition, processing timelines for cosmetic notification are further clarified, in particular, five working days for feedback on incomplete dossiers and five working days for approval after receiving complete supplemental dossiers. Revised requirements for import of samples for testing and research An updated Appendix 14-MP form is introduced with Circular 34, in which the receiving authority is updated from the Drug Administration of Vietnam to the specialized health agency under the provincial People’s Committee. Both online and direct submission of the request are allowed. The approval timeline is three working days from the date of reviewing the request. Transition clause Notifications

Instead, notification must be provided at least seven working days in advance, including the proposed destruction date and a detailed list of items to be destroyed. E-commerce in Pharmaceuticals Pharmaceutical businesses operating via e-commerce platforms must publicly disclose the following information to ensure transparency and consumer safety: (i) certificate of eligibility for pharmaceutical business, (ii) pharmacy practice certificate of the person responsible for pharmaceutical expertise, and (iii) drug information. Shelf-Life Requirements for Imported Products For drugs and ingredients with a total shelf life of nine months or less, at least one-third of the shelf life must remain at the time of customs clearance.
