Generic drug applications (GDAs) apply to therapeutic products which fall within the descriptions of “generic product” or “standard essential medicine”, as below:
Generic product
A generic product contains one or more chemical entities and is essentially the same as a current registered product (Singapore Reference Product) in terms of its qualitative and quantitative composition of active ingredients.
You may register your therapeutic product via GDA if it:
(a) Has the same pharmaceutical dosage form as the Singapore reference product.
(b) Has the same administration route as the Singapore reference product.
(c) Has conditions of use that fall within the directions for use (including indication, dosing regimen and patient group) for the Singapore reference product.
(d) Is bioequivalent with the Singapore reference product.
Note: Biosimilar or follow-on biologic products are not eligible for a GDA and are required to be submitted as a NDA.
Standard essential medicine
A standard essential medicine contains one or more chemical entities with documented long-standing local clinical use and has a well-established efficacy and safety profile.
You may register your therapeutic product via GDA if it does not have a corresponding Singapore reference product and it fulfils all of the following criteria:
(a) The therapeutic product is either included on:
- Ministry of Health (MOH) Standard Drug List (SDL) ; or
- A public healthcare institution’s Pharmacy and Therapeutics (P&T) List for a minimum of 5 years prior to the submission of the GDA;
(b) The requested indication(s) must be well-documented in at least one of the listed standard references 1;
(c) The product's quality must comply with:
- complete monographs for the drug substance and drug product of recognised pharmacopoeias 2; or
- complete monograph for the drug substance and minimum monograph requirements of recognised pharmacopoeias accompanied by one of the following:
- the product is approved and marketed in a reference jurisdiction for at least 5 years continuously prior to the submission of the GDA; or
- the product is supported by bioequivalence data against a reference product of a reference jurisdiction.
(d) The product has no known significant safety concerns in global markets; and
(e) The product has not been rejected or withdrawn due to quality, safety and/or efficacy issues by any national regulatory authority.
