GENERIC DRUGS FILING REQUIREMENTS - US VS EUROPE




GENERIC DRUG FILING REQUIREMENTS –
US VS EUROPE


A generic drug is identical--or bioequivalent--to a brand name drug in dosage form, safety, strength, route of administration, quality, performance characteristics and intended use.  Although generic drugs are chemically identical to their branded counterparts, they are typically sold at substantial discounts from the branded price. 

Generic Drugs are approved under ANDA (Abbreviated New Drug Application) in USA and MAA (Marketing Authorization Application) in Europe.


Abbreviated New Drug Application - USA
New drugs, like other new products, are developed under patent protection.  The patent protects the investment in the drug's development by giving the company the sole right to sell the drug while the patent is in effect.  When patents or other periods of exclusivity expire, manufacturers can apply to the FDA to sell generic versions.  The ANDA process does not require the drug sponsor to repeat costly animal and clinical research on ingredients or dosage forms already approved for safety and effectiveness.  

An abbreviated new drug application contains data, which when submitted to FDA’s ‘Center for Drug evaluation and research’ (CDER), office of generic drugs, provides for review and ultimate approval of a generic product. Once approved, the applicant may manufacture and market generic drug product to provide a safe, effective, low cost alternative to American public.

Marketing Authorization Application (Europe)
In Europe drug approval process is regulated by European Agency for evaluation of medicinal products (EMEA),this agency gives Marketing authorization in European union.
Pharmaceutical companies can use 4 approval procedures to market their pharmaceuticals.
·       A centralized or
·       Decentralized or
·       Mutual Recognition
·       National Procedure



Centralized Procedure: The centralised procedure allows the marketing of a medicine on the basis of a single EU-wide assessment and marketing authorisation which is valid throughout the EU. Pharmaceutical companies submit a single authorisation application to EMA. The Agency’s Committee for Medicinal Products for Human Use (CHMP) or Committee for Medicinal Products for Veterinary Use (CVMP) then carries out a scientific assessment of the application and gives a recommendation to the European Commission on whether or not to grant a marketing authorisation. Once granted by the European Commission, the centralised marketing authorisation is valid in all EU Member States.It Allows a pharmaceutical company to market its pharmaceutical products in all 30 EEA countries (27 EU Member States plus Iceland, Liechtenstein and Norway) (Applicant need not to obtain separate approvals for each member state).
The use of the centrally authorised procedure is compulsory for most innovative medicines, including medicines for rare diseases.

National Procedure: The national procedure only one member state is involved. The documents submitted to an authority are very specific to that particular authority and evaluation of the application is carried out by the same member state. The evaluation time for an application for a national marketing authorization is 210 days from the receipt of the application.

When a company wants to authorise a medicine in several Member States, it can use one of the following procedures:

Decentralised procedure: Where companies can apply for the simultaneous authorisation of a medicine in more than one EU Member State if it has not yet been authorised in any EU country and does not fall within the scope of the centralised procedure.

 Mutual-recognition procedure: Where companies that have a medicine authorised in one EU Member States can apply for this authorisation to be recognised in other EU countries. This process allows Member States to rely on each other’s scientific assessments.

VALIDATION VS CALIBRATION






 VALIDATION VS CALIBRATION





              
CALIBRATION
VALIDATION
Calibration is a demonstration that, a particular
Instrument or device produces results with in specified limits by comparisons with those produced by a reference or traceable standard over an appropriate range of measurements.

Validation is a documented program that provides high degree of assurance that a specific process, equipment, method or system consistently produces a result meeting pre-determined acceptance criteria.

In calibration performance of an instrument or device is comparing against a reference standard.

No such reference standards are using in validation program.
Calibration ensures that instrument or measuring devices producing accurate results.
Validation provides documented evidence that a process, equipment, method or system produces consistent results (in other words, it ensures that uniforms batches are produced).

Shall be performed periodically, to identify the ‘drift’ of the measuring device or equipment and make them accurate.

No such requirements. Shall be performed when changes or modifications happen to the existing system or once revalidation period is reached.

Shall be performed as per calibration SOP.
Shall be performed as per validation protocol.
