INDA



Introduction

An investigational new drug is a new drug or biological drug that is used in a clinical investigation. This term also includes biological products used in vitro for diagnostic purposes.The Investigational New Drug Application (IND) is a request for an exemption from the federal statute that prohibits an unapproved drug from being shipped in interstate commerce.
IND is not an application for marketing authorization of a drug. For the purpose of this lesson, “IND” is synonymous with “Notice of Claimed Investigational Exemption for a New Drug.”Upon completion of preclinical study and collection of data, the sponsor (the person who takes responsibility for and initiates a clinical investigation) must submit an application to FDA to notify FDA it is conducting a clinical study on human subjects.
 This application is called an Investigational New Drug Application (INDA or IND).Investigational new drug application abbreviated as INDA is a mandatory requirement filed with the FDA in order to seek permission for administering a new drug under investigation to Human subjects after completion of the preclinical studies on it.
2. It confers protection to the subjects and also sees that the investigational plan is efficient and designed to achieve its required objectives.
3. The sponsor of the drug is responsible for the initiation of clinical trials.
4. He might be an individual i.e. sponsor-investigator, a pharmaceutical company, governmental agency, academic institution or private or public organization.
5. The INDA is filed with the FDA under Title 21, Code of Federal Regulations Section 312- the guidelines for preapproval of all clinical testing’s are specified.
6. CONTENT OF INDA
[1] (i). All the requirements for submitting an INDA are prescribed in the Code of Federal Regulations and are submitted under a cover sheet (Form FDA- 1571) (1).
(ii). The items required are: – Name, address and telephone number of the sponsor of the drug. – Name and title of the person responsible for monitoring the conduct and progress of the investigation. – Names and titles of the persons responsible for the review and evaluation of information relevant to the safety of the drug. – Name and address of any contract research organization involved in the study (if any). -
Identification of the phase/phases of clinical investigation to be conducted. – Introductory statement and general investigational plan including, name of drug and all active ingredients, structural formula and pharmacological class, formulation, route of administration, and broad objectives and planned duration of study. – Description of the investigational plan.
The reason for selecting a drug or research study. Indications to be studied, approach to evaluation of the drug, types of studies, estimated number of subjects to be given the drug, and any risks anticipated based on animal studies. – Brief summary of previous experience with the drug, including reasons if the drug is withdrawn. -
Chemistry and manufacturing control information like physical, chemical and biologic characteristics, product stability during the clinical investigation. – Pharmacological and Toxicological information. -
If the drug is a combination of previously investigated components, then preclinical and clinical data of these components when given singly and in combination. – Clinical protocol for planned study. -
Commitment that an “Institutional Review Board” (IRB) has approved the study and will continue to monitor the investigation. – Investigators brochure. – Commitment not to begin clinical investigations until IND is in effect signature of the sponsor or authorized representative and the date of signed application.
7. After submission of IND to the FDA, it is assigned to the various divisions of Center for Drug Research and Evaluation wing of the FDA for its review and evaluation.
8. The FDA has 30days from the receipt of IND to decide whether the proposed clinical trial should proceed or not. If the sponsor is not contacted within 30days, the trial may proceed.
9. Meanwhile reviewers at FDA may put a “Clinical Hold” on the proposed Clinical trials at any time. This prevents human testing of drug. It may be due to the following reasons:[2] – If there is any unreasoned threat to the safety of the trial subjects i.e. if the subjects face any illness or injury due to treatment. – Insufficient data to assess patient risks. – If the investigators involved in the study do not meet the necessary requirements with respect their qualification. – Misleading or incomplete investigators brochure.
10. In case if all the requirements for FDA approval are satisfied an IND is granted. Once an IND is in effect, all the proposed changes to the original IND thereafter, must be submitted as amendments for approval.

  • Reference to previously submitted information;
  • Literature and publications in foreign language and their English translations; and
  • Any other relevant information.

IND Review Process

When the FDA receives the original IND, it assigns an IND number. This is the number that the applicant or sponsor should use in all correspondence with FDA regarding the application.
The application is then forwarded to the appropriate reviewing division. The reviewing division will send a letter to the sponsor-investigator providing notification of the IND number assigned, date of receipt of the original application, the address where future submissions to the IND should be sent, and the name and telephone number of the FDA representative to whom questions about the application should be directed.
INDs are not approved, they become effective 30 days after receipt by FDA
 if clinical hold (suspension or delay in clinical investigations) is not imposed.
Unless notified earlier by the FDA that studies may begin, the sponsor should
wait for 30 days to initiate clinical studies.

clinical Hold

A clinical hold is an order from the FDA to suspend or delay a proposed clinical investigation or to suspend an ongoing investigation. The most common reasons for a clinical hold include:
  • Unreasonable risk to subjects;
  • Investigator not qualified;
  • Investigator brochure misleading;
  • Insufficient information to assess risk;
  • Gender bias in a study in patients with life-threatening disease; and
  • Deficient study design

IND Maintenance

Once the IND is in effect, the sponsor must amend it as needed
to ensure that current information is submitted to FDA and
that FDA is aware of the changes. The three main sections we
will look at in this topic are Amendments (protocol and information),
IND Safety Reports, and Annual Reports.
Protocol Amendments
There are three types of protocol amendments:
  • New Protocol: For studies that are not covered by protocol already contained in the IND.
  • Change in protocol: To explain changes to the current protocol that significantly affect the safety of the subjects, the scope of the investigation, and scientific quality of the study (e.g., increase in drug dose, addition or dropping of a control group).
  • New investigator: When a new investigator is added to carry out a previously submitted protocol. The sponsor should notify FDA of the new investigator within 30 days of investigator being added.
The content and format of a protocol amendment:Clearly identify the amendment (e.g., “Protocol Amendment: New protocol” or Protocol Amendment: Change in Protocol”);
  1. Form 1571;
  2. In the case of new protocol, a copy of the new protocol and a brief description of significant difference from the previous protocol;
  3. In the case of new investigator, name and the qualifications (CV) and reference to the previous protocol; and
  4. Reference, if necessary, to specific technical information in the IND or submitted information.

Information Amendment

Report any change that is not within the scope of protocol amendment, IND safety report, or annual reports under the information amendment. Examples include new toxicology, chemistry, other technical information, or discontinuation of a clinical investigation.
An information amendment can be submitted as necessary, but not more frequently than every 30 days.
The content and format of the information amendment:Clearly identify the amendment with the information submitted (e.g., if it is CMC information, it shall bear the title, “Information Amendment: “Chemistry, Manufacturing and Control” or “Information Amendment: Pharmacology-Toxicology”);
  1. Form 1571;
  2. An statement explaining the nature and the purpose of the submission;
  3. The organized records and reports; and
  4. Organized data (if necessary).

IND Safety Reports

Report any adverse drug experiences or events associated with the use of the drug (laboratory findings) to FDA and all participating investigators:
  1. Adverse drug experience or event;
  2. Serious drug adverse experience (fatal or life-threatening, disability, inpatient hospitalization); or
  3. Unexpected drug adverse experience (not consistent with the current investigator brochure).
Submit to FDA a written report (from reported or observed adverse experience associated with the use of the drug and laboratory findings that suggests a significant risk for human subjects), along with form 3500A, as soon as possible (no more than 15 calendar days after the sponsor initially was notified).
In case of serious adverse events or unexpected serious adverse events, submit the report to FDA as soon as possible, but in no event later than 7 days after the receipt of the information by the sponsor.
Follow-up
  1. Sponsor shall promptly investigate all the safety and relevant information and submit the investigation report to FDA as soon as possible.
  2. The results of the sponsor’s investigation of other information shall be submitted to FDA in “Information Amendment” or “Annual Report.”
    The content and format of IND safety report:The report shall be clearly identified with the title “IND Safety Report”;
    1. Form 1571;
    2. Form 3500A; and
    3. Safety report and relevant information.
    FDA may ask the sponsor to submit the IND safety report in a different format and frequency than usually required.

Annual Reports

The annual report is sent to FDA to update the IND on the investigation progress and all changes that are not reported in amendments or other reports. Annual reports should be submitted within 60 days of the date that the IND went into effect.

Meetings with FDA

Issues always arise during clinical investigations. Meetings between the sponsor/applicant and the agency are useful in resolving these issues, and FDA encourages such meetings to the extent that they aid in the evaluation of the drug and in the solution of scientific problems concerning the drug.
Three types of meetings may be held between sponsors and FDA:
  • Type A meeting;
  • Type B meeting; and
  • Type C meeting.

End of Phase II (EOP2)/Pre-Phase III meeting

Purpose:
  1. To determine the safety of proceeding to Phase III clinical studies and address any CMC-related issues;
  2. To evaluate the Phase III plan and protocols and the adequacy of the current studies and plan to assess pediatric safety and effectiveness;
  3. To identify safety issues, scientific issues, and/or potential problems, and resolve them, if possible, prior to initiation of Phase III studies;
  4. and
  5. Any additional information necessary to support the marketing application.

Pre-NDA/BLA Meeting

Purpose:
  1. To discuss filing and data format issues;
  2. To uncover any major unresolved problems;
  3. To identify adequate and well-controlled studies to establish the drug’s effectiveness; and
  4. To discuss the technical information and statistical analysis method.

Withdrawal, Inactive Status, and Termination

Withdrawal
A sponsor may withdraw an effective IND without prejudice at any time. If an IND is withdrawn, FDA, all participating investigators, and all reviewing Institutional Review Boards shall be notified together with the reasons for such withdrawal. All clinical investigations conducted under the IND shall be ended and all stocks of the drug returned to the sponsor or otherwise disposed of at the request of the sponsor.


IND Termination

If an IND is terminated, the sponsor shall end all clinical investigations conducted under the IND, and recall or dispose of all unused supplies of the drug. A termination action may be based on deficiencies in the IND or in the conduct of an investigation under an IND.
FDA may propose to terminate an IND during Phase I if it finds that:
  • Human subjects would be exposed to an unreasonable and significant risk of illness or injury;
  • The IND does not contain sufficient information to assess the safety to subjects of the clinical investigations;
  • The methods, facilities, and controls used for the manufacturing, processing, and packing of the investigational drug are inadequate to establish and maintain appropriate standards of identity, strength, quality, and purity as needed for subject safety;
  • The clinical investigations are being conducted in a manner substantially different than that described in the protocols submitted in the IND;
  • The drug is being promoted or distributed for commercial purposes not justified by the requirements of the investigation or permission;
  • The IND, or any amendment or report to the IND, contains an untrue statement of a material fact or omits required material information;
  • The sponsor fails promptly to investigate and inform FDA and all investigators of serious and unexpected adverse experiences, or fails to make any other required reports;
  • The sponsor fails to submit an accurate annual report of the investigations;
  • The sponsor fails to comply with any other applicable requirement set forth in 21CFR parts 312, 50, and 56;
  • The IND has remained on inactive status for five years or more; or
  • The sponsor fails to delay a proposed investigation under the IND or to suspend an ongoing investigation that has been placed on clinical hold.
FDA may propose to terminate an IND during Phase II or Phase II if FDA finds that:
  • Any of the above conditions apply;
  • The investigational plan or protocol(s) is not reasonable as a bona fide scientific plan to determine whether or not the drug is safe and effective for use; or
  • There is convincing evidence that the drug is not effective for the purpose for which it is being investigated.
A terminated IND is subject to reinstatement by the Director on the basis of additional submissions that eliminate such danger. If an IND is terminated, the agency will offer the sponsor an opportunity for a regulatory hearing on the question of whether the IND should be reinstated.

Investigational New Drug (IND) Application


Introduction

Current Federal law requires that a drug be the subject of an approved marketing application before it is transported or distributed across state lines. Because a sponsor will probably want to ship the investigational drug to clinical investigators in many states, it must seek an exemption from that legal requirement. The IND is the means through which the sponsor technically obtains this exemption from the FDA.

During a new drug's (pharmaceutical ) 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. When a product is identified as a viable candidate for further development, the sponsor then focuses on collecting the data and information necessary to establish that the product will not expose humans to unreasonable risks when used in limited, early-stage clinical studies.

FDA's role in the development of a new ( pharmaceutical ) drug begins when the drug's sponsor (usually the manufacturer or potential marketer) having screened the new molecule for pharmacological activity and acute toxicity potential in animals, wants to test its diagnostic or therapeutic potential in humans. At that point, the molecule changes in legal status under the Federal Food, Drug, and Cosmetic Act and becomes a new drug subject to specific requirements of the drug regulatory system.or pharmaceutical regulatory systems
There are three IND types:

1.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 physician might submit a research IND to propose studying an unapproved drug, or an approved product for a new indication or in a new patient population.

2.Emergency Use IND 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.

3.Treatment IND is submitted for experimental drugs (pharmaceuticals ) showing promise in clinical testing for serious or immediately life-threatening conditions while the final clinical work is conducted and the FDA review takes place.
There are two IND categories:

1.Commercial

2.Research (non-commercial)

The IND application must contain information in three broad areas:

1.Animal Pharmacology and Toxicology Studies - Preclinical data to permit an assessment as to whether the product is reasonably safe for initial testing in humans. Also included are any previous experience with the drug ( pharmaceutical ) in humans (often foreign use).

2.Manufacturing Information - Information pertaining to the composition, manufacturer, stability, and controls used for manufacturing the drug substance and the drug product. This information is assessed to ensure that the company can adequately produce and supply consistent batches of the drug.

3.Clinical Protocols and Investigator Information - Detailed protocols for proposed clinical studies to assess whether the initial-phase trials will expose subjects to unnecessary risks. Also, information on the qualifications of clinical investigators--professionals (generally physicians) who oversee the administration of the experimental compound--to assess whether they are qualified to fulfill their clinical trial duties. Finally, commitments to obtain informed consent from the research subjects, to obtain review of the study by an institutional review board (IRB), and to adhere to the investigational new drug regulations.

Once the IND is submitted, the sponsor must wait 30 calendar days before initiating any clinical trials. During this time, FDA has an opportunity to review the IND for safety to assure that research subjects will not be subjected to unreasonable risk.

Resources for IND Applications

The following resources have been gathered to provide you with the legal requirements of an IND application, assistance from CDER to help you meet those requirements, and internal IND review principles, policies and procedures.
Pre-IND Consultation Program: CDER offers a Pre-Investigational New Drug Application (IND) Consultation Program to foster early communications between sponsors and new drug review divisions in order to provide guidance on the data necessary to warrant IND submission. The review divisions are organized generally along therapeutic class and can each be contacted using the designated Pre-IND Consultation List.

Guidance Documents for INDs  , Are available over US FDA'S website for pharmaceuticals regulatory

Guidance documents represent the Agency's current thinking on a particular subject. These documents are prepared for FDA review staff and applicants/sponsors to provide guidelines to the processing, content, and evaluation/approval of applications and also to the design, production, manufacturing, and testing of regulated products. They also establish policies intended to achieve consistency in the Agency's regulatory approach and establish inspection and enforcement procedures. Because guidances are not regulations or laws, they are not enforceable, either through administrative actions or through the courts. An alternative approach may be used if such approach satisfies the requirements of the applicable statute, regulations, or both. For information on a specific guidance document, please contact the originating office.

For the complete list of CDER guidances, please see US FDA'S website for these guidance documents.
