3. PHARMACEUTICALS MAY MOVE ACROSS STATE LINES DURING
TWO STAGES OF HUMAN USE
• Research prior to “approval”
e.g., New Drug application
– Requires research permit: New Drug Exemption (IND)
e.g., Investigational application
• Marketing after “approval”
– Requires marketing permit: Application (NDA)

4. PRE-CLINICAL TESTING
• When new drugs show promise in lab testing, studies
are designed to evaluate them further.
• These studies in animals are referred to as “pre-clinical
studies.”

5. PRE-CLINICAL TESTING
• Pre-clinical studies help establish boundaries for safe use of the treatment
if/when human studies begin. (Animal Models :- to test drugs & side effects)
• Many new drugs and treatments are abandoned at this step because they are
proven unsafe.

6. CLINICAL RESEARCH AND DEVELOPMENT
• The application to the FDA to request permission to begin human testing is
called an Investigational New Drug application, or IND.
• The IND permits the use of an investigational new drug for the sole purpose of
conducting clinical trials.

7. DRUG-DISCOVERY, DEVELOPMENT & ITS APPROVAL
It takes 12-15 years on an average for an experimental drug to travel from the lab to the patients. Only 5 in
5000 compounds that enter the pre-clinical testing stage, make it to the human-testing stage. One of these 5
tested on people is approved.

8. INVESTIGATIONAL NEW DRUGAPPLICATION (IND)
• An Investigation New Drug Application (IND) is a submission to Food & Drug
Administration (FDA) requesting permission to initiate the study of New drug
product
• In many ways, the investigational new drug (IND) application is the result of a
successful preclinical development program.
• The IND is also the vehicle through which a sponsor advances to the next stage of
drug development known as clinical trials (human trials).
• During a new drug's early preclinical development, the sponsor's primary goal is to
determine if the product is reasonably safe for initial use in humans, and if the
compound exhibits pharmacological activity that justifies commercial development.
• The standard for approval is evidence of safety and efficacy
• The IND exemption is granted for purposes of clinical investigation (research)

9. IMPORTANCE OF THE IND
• Affirms a body of knowledge about the manufacturing, pharmacology, and
toxicology of the drug to support its use in human testing
• Requires that the clinical investigation(s) be performed in accordance with Good
Clinical Practice (GCP)
• Provides an additional level of protection through FDA oversight

10. • There are three IND types:
Investigator IND
Emergency Use IND
Treatment IND
• There are two IND categories:
Commercial (Ultimate goal is to achieve marketing approval for new product)
Research (non-commercial)
TYPES OF IND

11. INVESTIGATOR/SPONSOR IND
• An Investigator IND is submitted by a physician who both initiates and conducts
an investigation, and under whose immediate direction the investigational drug
is administered or dispensed .
• A Research IND is to be submitted for proposed study of
Unapproved drug
Approved product for
• New indication
• New patient population
• Motivation is not necessarily commercial in nature.

12. EMERGENCY USE IND
• It allows the FDA to authorize use of an experimental drug in an emergency
situation that does not allow time for submission of an IND in accordance
with 21CFR , Sec. 312.23 or Sec. 312.34
• It is also used for patients:
 who do not meet the criteria of an existing study protocol
 or if an approved study protocol does not exist.
 Reserved for life-threatening situations
No standard acceptable treatment is available

13. TREATMENT IND
• The treatment IND [21 CFR 312.34 and 312.35] is a mechanism for providing eligible
subjects with investigational drugs for the treatment of serious and life-threatening
illnesses for which there are no satisfactory alternative treatments.
• Experimental drugs showing promise in clinical testing-safety and efficacy.
• After completion of Phase I and II
Used for the treatment of serious or life threatening conditions
• No alternate treatments available
• AIDS, Cancer
 Made available while final clinical testing is completed and reviewed by the FDA
 Reduce reluctance of people to participate in expanded drug access programs

14. WHO CAN APPLY FOR IND????
• Applicant (Drug Sponsor)
• An applicant, or drug sponsor, is the person or entity who
assumes responsibility for the marketing of a new drug, including
responsibility for compliance with applicable provisions of the
Federal Food, Drug and Cosmetic Act and related regulations.
• The "sponsor" Is usually An individual, partnership, corporation,
Government agency, manufacturer or scientific institution.

15. • The IND application provides FDA with data necessary to decide whether the new drug
& the proposed Clinical trial pose a reasonable risk to human subjects participating in
the study.
• The IND application allows the company to initiate & conduct the clinical studies of
their new drug Product.
• The safety of the Clinical trial Subjects is always the primary concern of FDA.
• When preparing the IND & throughout the Drug development process the primary
goal of the Sponsor should be to demonstrate to the FDA that the
-new drug
-proposed trial
-entire clinical development plan described in the IND is designed to minimize the risk
to the trial subjects.

16. WHEN DO WE NEED AN IND?
• An IND would be required to conduct a Clinical trial if the drug is –
-A new chemical entity not approved for the indication under
Investigation in the new dosage form.
- being administered at the new dosage level.
-In combination with another drug & the combination is not approved.

followed by CDER staff to help standardize the new drug review
process and other activities.

34. The Investigational New Drug (IND) Process:
Drug developers, or sponsors, must submit an Investigational New Drug (IND)
application to FDA before beginning clinical research. In the IND application,
developers must include:
• Animal study data and toxicity (side effects that cause great harm) data
• Manufacturing information
• Clinical protocols (study plans) for studies to be conducted
• Data from any prior human research
• Information about the investigator

35. FDA APPLICATION PROCESS
• IND contains:
• sufficient Chemistry, Manufacturing, and other Controls
• pre-clinical safety information describes the proposed human trial (Phase 1
• Multi-disciplinary Review Team
• 30-Day Deadline for Decision
• Team Decision
• Yes? “Okay to Proceed” No? Clinical HOLD
• Communication to sponsor: What work must sponsor do to get HOLD lifted?

36. FDA REVIEW OF THE INDA
 Once the IND stamped as received ,it is sent to the review division
within CDER.
 On arrival at the review division , it is critically evaluated byseveral
reviewers of
Chemist
Biopharmaceutics
Medical
Stastistics
Microbiology
Pharmacology /toxicology sections

39. INDA REVIEW PROCESS OVERVIEW

40. FDA’SIND REVIEW PROCESS
• Safety Review:
• Following review of an initial IND submission, CDER has 30 calendar days in which to
decide if a clinical hold is necessary (i.e., if patients would be at an unacceptable
risk or if CDER (Center for Drug Evaluation and Research) doesn't have the data to make such
a determination).
• Generally, drug review divisions do not contact the sponsor if no concerns arise with
drug safety and the proposed clinical trials.
• If the sponsor hears nothing from CDER, then on day
31 after submission of the IND, the study may proceed as submitted.

41. CLINICAL HOLD DECISION
• A clinical hold is the mechanism that CDER uses when it does not believe, or cannot
confirm, that the study can be conducted without unreasonable risk to the
subjects/patients.
• If this occurs, the Center will contact the sponsor within the 30-day initial review
period to stop the clinical trial. CDER may either delay the start of an early-phase trial
on the basis of information submitted in the IND, or stop an ongoing study based on
a review of newly submitted clinical protocols, safety reports, protocol amendments,
or other information.
• When a clinical hold is issued, a sponsor must address the issue that is the basis of
the hold before the order is removed

42. • CLINICAL HOLD
a clinical hold can be –
- “complete clinical hold” – a delay or Suspension of all
clinical work requested under IND submission
- “partial clinical hold”- a delay or suspension of only part of
clinical work e.g. part of protocol.

43. NOTIFYSPONSOR
• Once a clinical hold is placed on a commercial IND, the sponsor will be notified
immediately by telephone by the division director.
• the division is required to send a letter within five working days following the
telephone call.
• The letter should describe the reasons for the clinical hold, and must bear the
signature of the division director (or acting division director).
• The sponsor may then respond to CDER by sending an "IND CLINICAL HOLD
RESPONSE" letter to the division. To expedite processing, the letter must be clearly
identified as an "IND CLINICAL HOLD RESPONSE" letter.

44. • The division then reviews the sponsor's response and decides
within 30 days as to whether the hold should be lifted.
• If the division does not reply to the clinical hold response within
30 calendar days, the division director will telephone the sponsor
and discuss what is being done to facilitate completion of the
review.
• If it is decided that the hold will not be lifted, the hold decision is
automatically sent to the office director for review.

45. • The office director must decide
calendar days whether or not to
within 14
sustain the
division's decision to maintain the clinical hold.
• If the decision is made to lift the hold, the division telephones the
sponsor, informs them of the decision, and sends a letter
confirming that the hold has been lifted.
• The letter will be sent within 5 working days of the telephone call.
However, the trial may begin once the decision has been relayed
to the sponsor by telephone.

46. SPONSORNOTIFIEDOFDEFICIENCIES
• If other deficiencies are found in an IND that the review division determines are not
serious enough to justify delaying clinical studies, the division may either telephone
or forward a DEFICIENCY LETTER to the sponsor.
• In either case, the division informs the sponsor that it may proceed with the planned
clinical trials, but that additional information is necessary to complete or correct the
IND file, or that there are issues that need to be addressed prior to a marketing
application (NDA) submission.

47. STUDYONGOING
• Once CDER's 30-day initial review period expires, clinical studies can
be initiated, unless a clinical hold has been placed.

48. INDA ANNUALREPORTS
 Sponsors should submit an annual report that provides the FDA with
a brief update on the progress of all investigations included in the
IND.
 It should contain the following:
Individual study information.
Summary of the study.
Listing of any significant foreign marketing developments with the
drug e.g. approval in another country.
