The document discusses Investigational New Drug (IND) applications and Abbreviated New Drug Applications (ANDAs). It defines an IND as a new drug or biological used in clinical investigation. The sponsor submits an IND application to the FDA or DCGI to begin clinical trials in humans. Clinical trials can start 30 days after IND submission if not objected to by the FDA. ANDAs allow for generic drug approval without full clinical trials, as long as they are equivalent to an existing brand drug in dosage, strength, quality and performance. The process for IND and ANDA approval in both the US and India is described.

4. âą Investigational New Drug is defined
under 21 CFR 312.3(b) as â a new
drug or biological drug that is used in
clinical investigationâ.
âą After pre-clinical investigations when
the new molecule has been screened
for pharmacological activity and acute
toxicity potential in animals the
sponsor requires permission from
FDA for its clinical trials in humans.
INVESTIGATIONAL NEW DRUG
(IND)
5. âą The sponsor submits the application for conduct of
human clinical trials called Investigational New
Drug (IND) application to FDA or DCGI .
âą Once IND application is submitted , the sponsor
must wait for 30 days before initiating any clinical
trial.
âą Clinical trials in humans can begin only after IND
is reviewed by the FDA and a local institutional
review board (IRB).
âą IRBs approve clinical trial protocol, informed
consent of all participants and appropriate steps to
prevent subjects from harm.
6. âą If the FDA accepts the IND request within 30 days
of submission, clinical testing of the new molecule
on human may begin by the investigator.
âą At this point, the molecule under the legal status
of FDA becomes a new drug subject to specific
requirements of drug regulatory system.
âą If at any time during clinical testing, the data
furnished to FDA indicate the IP to be toxic under
the criterion of FDAâs Benefit/Risk ratio, FDA can
terminate clinical trial and its actions are not
subject to any judicial review.

8. ïThe IND application must contain information in 3
broad areas:
i. Animal Pharmacology and toxicology studies-
Preclinical data to assess if the product is
reasonably safe for initial testing in humans. Also
, included are any previous with drug in humans.
ii. Manufacturing information- Information
pertaining to composition, manufacturer, stability
and controls used for manufacturing drug product
to ensure that the company can adequately
produce and supply consistent batches of the
drug.
9. iii. Clinical Protocol and Investigator
information
ï Detailed protocols for proposed clinical
ï studies to make sure subjects are not
ï exposed to undue risks. Also,
information on
ï the qualifications of the investigators
(chiefly
ï physicians) if they fulfill their clinical
duties.
ï Finally, commitments to obtain informed
ï consent from all research subjects, to
obtain
ï review of the study by an IRB and to
adhere
ï to the investigational new drug

Format and content of IND
13. ï At any time a sponsor can withdraw an effective IND . In such a case,
FDA and IRB shall be so notified with reasons for withdrawal, all clinical
studies ended, all current investigators and subjects notified, all stocks
of drug returned to the sponsor or otherwise disposed off on request of
sponsor in accordance with 312.59.
WITHDRAWAL OF an IND
14. ï IND has been defined under Rule 122-DA (3) of
Drugs and Cosmetics Rules 1945 as a chemical
entity having therapeutic indication but which have
never been earlier tested on humans.
ï No clinical trial for new drug for any purpose be
conducted without permission , in writing, of the
Licensing Authority (DCGI).
ï Application for conducting clinical trials in India
require submission by the sponsor on Form 44
along with requisite fee (Rs 50k) and documents
as provided under Schedule Y to Drugs and
Cosmetics Act 1940.
IND PROCESS IN INDIA
15. ïData to be submitted along with the
application on Form44 to conduct
clinical trials (2 hard copies and 2 soft
copies i.e., CDs in PDF format)
1. Application on Form 44
2. Introduction of the drug
3. Fee Rs 50K through challan form
4. Chemical and Pharmaceutical
information as per Appendix I of
Schedule Y
5. Animal Pharmacology as per
Appendix IV
6. Animal Toxicology as per Appendix III
7. Human/Clinical Pharmacology data
as per Appendix I
8. Regulatory status in other countries
16. After receiving the
application, the CDSCO
Headquarters in New
Delhi refer it to
The New Drug division
where it is reviewed by
IND committee. The
Committee submits its
report to
To DCGI along with its
recommendations. If the
report by Committee is
favorable, DCGI approves
the INDA.
17. ï It takes 4-6 months for the approval but it is not
documented. The Ethical Committee also requires
1-3 months time. Thus , it almost takes 7-9 months
for approval of INDA from DCGI.
ï For international applicants, import license to
import IP samples and permission from Director
General Foreign Trade to export blood samples is
also needed.
19. âA drug product that is comparable to a brand/reference listed drug product in
dosage form, strength, route of administration, quality and performance
characteristics, and intended useâ
It termed "abbreviated" because they generally not required to include
preclinical (animal) and clinical (human) data to establish safety and
effectiveness.
Basic Generic Drug Requirements are:--
ï Same active ingredient(s)
ï Same route of administration
ï Same dosage form
ï Same strength
ï Same conditions of use
ï Inactive ingredients already approved in a similar NDA

20. ï To reduce the price of the drug.
ï To reduce the time development.
ï Increase the bioavailability of the drug in
comparison to references list drug.

24. A generic drug is considered to be
bioequivalent to the brand name drug if:
ï The rate and extent of absorption do not
show a significant difference from listed
drug, or
ï The extent of absorption does not show a
significant difference and any difference in
rate is intentional or not medically
significant
