3. New Drug Application
ī Introduction
Critical component for drug approval process
which required to submit to USFDA before drug
commercialization.
The data gathered during the animal studies and
human clinical trials of an Investigational New Drug
(IND) become part of the NDA.
ī Goal
The NDA provide enough information to permit
FDA reviewer to reach safety, efficacy and quality for
pharmaceutical production

20. ANDA
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:--
ī Same active ingredient(s)
ī Same route of administration
ī Same dosage form
ī Same strength
ī Same conditions of use
ī Inactive ingredients already approved in a similar NDA 20
21. Goal of ANDA
ī To reduce the price of the drug.
ī To reduce the time development.
ī Increase the bioavailability of the drug in comparison
to references list drug.
21
23. NDA vs. ANDA Review Process
NDA Requirement ANDA Requirement
23
24. What is Bioequivalence?
A generic drug is considered to be bioequivalent to the brand
name drug if:
ī The rate and extent of absorption do not show a significant
difference from listed drug, or
īThe extent of absorption does not show a significant
difference and any difference in rate is intentional or not
medically significant
24
25. Patent Certification condition for
ANDA
Described in section 505(j)(2)(A)(vii) of the Act.
ī§ I Patent Not Submitted to FDA â
Approval effective after OGD scientific determination
ī§ II Patent Expired â
Approval effective after OGD scientific determination
ī§ III Patent Expiration Date (honored) â
Tentative approval after OGD scientific determination, final
approval when patent expires
ī§ IV Patent Challenge â
Tentative approval after OGD science determination, final
approval when challenge won
25
26. Paragraph IV certification
According to section 505(j)(2)(B)(i), 2157 CFR
ī The ANDA applicant must provide appropriate notice of a
paragraph IV certification to each owner of the patent that
is the subject of the certification and to the holder of the
approved NDA to which the ANDA refers
And by Section 505(j)(5)(B)(iv)
ī An incentive for generic manufacturers to file paragraph IV
certifications and to challenge listed patents as invalid, or
not infringed, by providing for a 180-day period of
marketing exclusivity
26
27. Patent Challenge Successful â Award
of 180-Day Exclusivity Period
īAwarded to first ANDA holder to file a complete
application with patent challenge
īProtection from other generic competition â blocks
approval of subsequent ANDAs
īProtection triggered by:
First commercial marketing
Forfeiture provisions
27
28. Orphan Drug Exclusivity (ODE)
īOrphan drug refers to a product that treats a rare disease -
affecting fewer than 200,000 Americans
ī7 years exclusivity
ī Granted on approval of designated orphan drug
ī OGD works with the Office of Orphan Products
28
30. CONCLUSION
NDA
ANDA
Applicable for new drug Applicable for generic drug
Take longer time ( 12-15
years)
Compare to NAD less time
taken(1-2 years)
More expenditure of money Comparatively less
Cost of drugs are more Cost of drugs are less
Nonclinical studies and clinical
investigations are essential
Nonclinical studies and clinical
investigations are nonessential
except bioavailability and
bioequivalence
