Not the view of DRAP

Current judgment of speaker

No obligation on DRAP

Regulatory experience

It has nothing to do with any specific

commercial product or organization

It is just a knowledge sharing exercise

nothing more than that

Clinical trial

New Drug Approval

Generic Drug Approval

Manufacturing Standards

Surveillance & Monitoring

Global language

Lets have a quick look on history and to clean the wind screen

Mal-practices in drug manufacturing

Regulations came into force

Tragedies occurred

Regulations continue to be stringent & complex

Historical Perspective

About Half a billion population died

4Lakh per year in Europe

Very near to your and your beloved one’s lives

Drug Safety from Pre Market to Post Market"DO YOU KNOW IN 2008 ....., used to stop

bleeding during open heart surgery killed a lot of patients.

The lives of 22,000 patients in USA alone could have been saved if U.S. regulators had

been quicker to ban it. The same was extensively used in Pakistan too but no body

knows, it killed how many in our country

Over sulfated chondroitin sulfate (OSCS)

149 deaths

Test was passed

Signals not responded

Finally contamination

detected

Let’s think together

If it happened in Pakistan, were me & you able to catch?

What do you think can it be caught in testing?

Do you think we are capable to catch such level of contaminant or less?

No

YesDon’t know

100’s of

Deaths

Clinical Trial

CLINICAL TRIALS

Phase 1: Efficacy studies on healthy volunteers

Phase 2: Clinical studies on a limited scale

Phase 3: Comparative studies on large number of patients

CLINICAL TRIALS/STUDIES (Cont’d)

New Drug Application (NDA): Regulatory review

Phase 4: Continued comparative studies Registration and market introduction

Pre-clinical Studies

Clinical studies (Phases 1-3)

NDA RA Review Approval

Post approval evaluation/

Phase4

Review of new drugs for approval, hold and ban

Extensive screening, examination, assessment, review and evaluation for

reasonable science based decision.

Continuous oversight and surveillance

Evaluates the research on the safety of the drug and

its effectivenessReviews the information to go on the drug label

Inspects the facilities where the drug will be

manufactured

The application will be classified as

“approvable” or “not approvable”

RA Role on NDA passed through IND

RA Role on NDA

If approvable, the RA requests additional information from the sponsor

The NDA is again reviewed

Following drug approval, sponsors of the drug will be required to continually assess the safety of the drug

Bioavailability

Generic Drug Approval

1. Labeling

2. Biopharmaceutical Evaluation

3. Chemistry, Manufacturing & Controls

4. Plant Inspection

Who will be responsible if any adverseevent or safety issue is identified?

Innovator or Generic?

If innovator discontinued drug due to any reason and new ADR appears

What will happen?
