How are Drugs Regulated and Approved in Singapore?
Selling and exporting of the New or Generic drugs can be only done after obtaining a valid product license. The application for license needs to be submitted to the Singapore Health Sciences Authority (HSA) and requires common technical document (CTD) format which is designed by ICH (International Conference on Harmonization). The manufacturer or import should have ICH designed Association of Southeast Asian Nations (ASEAN).
The Applicant should know the type of product application and route for the evaluation of the drug in case of therapeutic products and the applicant need to attend HSA pre-submission consultation which helps in differentiating the drug between chemical and biological therapeutic products. In Singapore classifies the application into two categories which are NDA (New drug Application) and GDA (Generic Drug Application). GDA Applies to the chemical and does not apply to the biosimilar drugs (Submitted via NDA).
Which Authorities Regulate Drugs In Singapore?
- Ministry of Health
- Association of southeast Asian Nations (ASEAN)
- Health Products Act – It regulates the registration, supply, import, manufacture, storage, packaging and advertising of the products including therapeutics, cosmetics and medical devices in Singapore.
- Health Sciences Authority (HSA) – The key authority and multi-disciplinary agency in Singapore which regulates the drugs jurisdiction of medical and biological drugs.
HSA Pre-registration Requirements:
To register a pharmaceutical product in Singapore, manufacturers must fulfill specific pre-registration requirements:
1. Pharmaceutical Manufacturing License: Manufacturers must hold a valid pharmaceutical manufacturing license granted by either the Health Sciences Authority (HSA) or a comparable foreign regulatory body.
2. Qualified Person: A Qualified Person (QP) must be designated to guarantee adherence to regulatory obligations during the entire manufacturing process.
List of Documents Required by HSA:
During the registration process, the following documents may be required:
- Product information, including composition, manufacturing process, and specifications.
- Stability data.
- Clinical trial data (if applicable).
- Bioequivalence data (for generics).
- Quality testing data.
- Packaging and labelling information.
Process of Drug Registration by HSA
Therapeutic Drug Registration:
It is extremely important to find the type of application of the drug which is to be registered via registration guides. There are two types of applications which are-
I. New Drug Application (NDA)
II. Genetic Drug Application (GDA)
HSA regulates the generic drugs and handles the registration of pharmaceutical products. The importer should have a person as registrant from Singapore which will be responsible for safety, efficacy and the quality of the product and applicant needs to have a local company in Singapore which is registered with Accounting and Corporate Regulatory Authority (ACRA).
PRISM- The drug application in the ICH CTD format is registered through the online/electronic/e-service platform which is generally known as PRISM (Pharmaceutical Regulatory and Information System). E-service gives convenience to customers and authority.
They can only be registered after the evaluation of the drugs. There are 3 routes of evaluation which are-
I. Verification route
II. Abridged route
III. Verification evaluation route (CECA Scheme)
Notification process
After the approval of the application, if the HSA finds that the application is satisfying the requirements of quality, efficacy and safety, the product is included in the therapeutic products register by the authorities.
CPP (Certificate of Pharmaceutical product) is issued for registered or un-registered products which are to be exported or evaluated. The therapeutic product needs to be manufactured under the quality compliance according to the GMP Standards mandated by WHO.
New Drug Application (NDA) (HSA)
These drugs are composed of new chemical and biological entities. NDA covers therapeutic products under 3 categories;
- NDA 1- First strength of new chemical or biological entity which are currently not existed or registered in Singapore.
- NDA 2- Products which does not fall in NDA-1,NDA-3 OR GDA products and first strength products, or the products which are registered by the new route of administration or patient population, new indication and dosage recommendation.
- NDA 3- Subsequent strength of products which are already registered and the product name, dosage and patient population should be same as NDA-1 and NDA-2 submission.
Biosimilar Products-
They are the therapeutic products which are very similar to existing biological products in physicochemical characteristics, safety, biological activity and efficacy. These products are submitted via NDA-2 or NDA-3.
Generic Drug Application(GDA)
This application applies on the therapeutic product which consists of one or more chemicals. The GDA Application can only be registered if the drug meets the criteria which should be according to Singapore reference products. There are 2 types of GDA Application to register and market the drugs in Singapore;
- GDA 1 – First strength of generic chemical product submission.
- GDA 2- Subsequent strength of generic product which is already submitted as GDA-1 and the product and dosage should be same as first strength product.
Timeline for registration of drugs by HSA-
NDA: It takes 50 days for screening application for all the evaluation routes but the evaluation time for different routes is between 60- 270 days.
- 60 days- verification evaluation routes
- 180 days- Abridged evaluation
- 270 days- Full evaluation time
GDA: It takes about 50 days for the screening of the application which starts from the day when the registrant receive the receipt for the application dossier and the screening time can be increases if the applicant needs to provide any clarification or additional document. Given below are the time taken for the evaluation of drugs.
- 120 days- Verification evaluation route
- 90 days – Verification evaluation route (CECA scheme),
- 14 days – Verification evaluation route first communication.
- 240 days – Abridged evaluation route.
