Ensuring Smooth Registration of Pharmaceutical Products

Subscribe to Updates
PReMA Life

The registration of a pharmaceutical product with the Food and Drug Administration (FDA) can be extremely time consuming, even for straightforward cases. In order to avoid any delays, it is important that the product dossier be meticulously prepared prior to submitting all relevant documents to the FDA, especially the quality part of the documentation.

We discussed the issue with the Department of Medical Science (DMSc) quality part examiners to clarify the process, provide key pointers to avoid common mistakes, and obtain their views and opinions on some of the most common difficulties typically encountered when reviewing a dossier.

Regulatory Changes

Due to changes in requirements from ASEAN Harmonization of Standards and Technical Requirements for Pharmaceutical Products, applicants should carefully follow the developments of the regulations for product registration to ensure that there are no missing documents and that they have not overlooked any newly introduced requirements.

Method Verification and Method Validation

New applications will likely have to be filed for all non‐ASEAN compliant pharmaceutical products, or amendments will have to be made to the quality part of such products. This includes the Method Verification and Analytical Method Validation aspects.

The Method Verification is the confirmation procedure by performing the analytical method in complying with the compendia method for the users of such methods. The manufacturers who use the United States Pharmacopoeia analytical method have to demonstrate their competence in successfully operating the method by providing the documents to verify the suitability of such methods.

The Analytical Method Validation is a confirmatory process of performing several tests which are designed to verify that an analytical test system is suitable for its intended purpose, and is capable of providing useful and valid analytical data. Thus, Analytical Method Validation is required for a newly developed method, non compendia, such as an in‐house method (i.e., a method that was developed by the manufacturer itself), and modified compendia procedures etc.

Applicants should also ensure that references from pharmacopoeia are not obsolete when submitting documents for the analytical part of the assay.

Zone IVb Stability Data

All previously registered pharmaceutical products have until 2012 to amend the stability data provided in their respective dossiers. Zone IVb stability data of 30 C +-2, 75 +-5% RH is now required. This includes long term and real time Zone IVb Stability data, which is a new requirement

Carefully prepared data that meets the FDA guidelines will hopefully avoid any unnecessary delays and ensure the earliest and smoothest product launch.

Following the recent delisting of almost all parts of the hemp plant from Thailand’s list of prohibited narcotics (see here for further details), the Ministry of Public Health has issued a notification allowing hemp to be used in cosmetics. Prior to this development, this use of hemp (whether from natural or synthetic sources) was not allowed, as it fell under the definition of narcotics under the Notification Re: Ingredients Not Allowed for Use in Cosmetics B.E. 2559 (2016). Under the Ministerial Notification Re: Use of Hemp in Cosmetics B.E. 2564 (2021), which was published in the Government Gazette on January 11, 2021, domestic manufacturers are now allowed to produce cosmetics containing hemp seed oil or hemp seed extract, provided the cosmetics do not have a THC level exceeding 0.2% by weight. To register such products with the Thai FDA, applicants must submit a certificate of analysis, safety data sheet, and label for the agency’s evaluation. The timeline for approval of the registration (notification) of a cosmetic containing hemp seed oil or hemp seed extract is three business days. The applicant (i.e., manufacturer or toll manufacturer) must declare the amount of hemp seed extract or hemp seed oil used in the cosmetic in their notification application. Cosmetics must not use a name for the product that evokes an association with hemp flowers or narcotics, and the name of the product must be within the scope of cosmetics. For example, names containing “inflorescence,” “flower,” “CBD,” “THC” or similar will not be allowed. It should also be noted that Thailand does not yet allow the importation of cosmetics containing hemp seeds or hemp seed extract, and this regulation only applies to domestically produced hemp products—a business currently restricted to individuals or companies with Thai nationality.

Across the globe, the demand for COVID-19 vaccinations has been understandably high, with many regulatory authorities (e.g., U.S. Food and Drug Administration, Medicines & Healthcare Products Regulatory Agency in the U.K., European Medicine Agency, Swissmedic, etc.) issuing emergency use authorizations for COVID-19 vaccines. Similarly, the Thai Food and Drug Administration (Thai FDA) has published the Notification Re: Conditional Approval for Emergency Use of Medical Products, which allows drug importers to register COVID-19 vaccines under the conditional approval scheme.  While as of the date of this article, the Thai FDA has yet to authorize any COVID-19 vaccines, this should follow shortly as clinical trials are completed and government procurement negotiations progress. Under the notification, it appears that the channel of distribution of a COVID-19 vaccine under the conditional approval scheme would be strictly controlled by the Thai FDA. This channel includes the vaccine’s distribution to relevant government agencies (e.g., Department of Disease Control of Thailand and public hospitals specified by the Thai FDA). However, questions have been raised regarding which private hospitals would be included in the distribution list and how the Thai FDA would distribute the vaccine to private hospitals. This confusion over the role of private hospitals was seen recently when one private hospital advertised that it could secure the COVID-19 vaccine from one developer whose product had already been approved elsewhere, until the Thai FDA then stepped in and claimed that the advertisement violated the Drug Act. The Thai FDA notification also enumerates several essential criteria that must be fulfilled in seeking approval for a COVID-19 vaccine, including the following: The available scientific data must substantiate both the efficacy and safety of vaccine. Further, the risk-benefit analysis must indicate that the medicine’s benefits outweigh its risks. A risk management plan, including risk minimization measures, must be submitted.

At a meeting on December 21, 2020, the Thai Board of Investment (BOI) approved a series of stimulus packages aimed at encouraging local and foreign investment, as the government seeks to boost Thailand’s economic recovery from the COVID-19 pandemic. The additional investment incentives, which will be promoted by the BOI in the upcoming year, include a number of sector- and project-specific stimulus measures.   Additional Tax Incentives for Large-Scale Projects Projects in target industries with investment of at least THB 1 billion (approx. USD 33 million) over a 12-month period, starting from the issuance of the BOI promotion certificate, will be entitled to an additional 50% corporate income tax (CIT) deduction for a period of five years, calculated on top of the standard 5–8 year CIT exemptions offered under the normal BOI tax-incentive scheme. To obtain this special tax incentive, eligible projects may apply to the BOI from January 4 to December 30, 2021.   Stimulus Package for Digital Economy and Software Industry Projects that support digital technology adoption, such as software integration, artificial intelligence, machine learning, or big data analytics, may benefit from 50% CIT exemptions on profits generated from their existing BOI projects for an additional three years. Applications for the exemption must be submitted by the end of 2022.   Application Deadline Extensions for Special Economic Zones and Five Southern Provinces Measures relating to special economic zones cover more than 300 investment promotion categories, with both tax and non-tax incentives, including an additional tax incentive for target industries such as textiles, agriculture, home furniture, jewelry, and others. These incentives are available to projects located in the border areas of Thailand (i.e., the 10 special economic zones in the provinces of Chiang Rai, Kanchanaburi, Mukdahan, Nakhon Phanom, Narathiwat, Nong Khai, Sa Kaeo, Songkhla, Tak, and Trat), with the
