INVESTIGATIONAL NEW DRUG (IND)Tushar Premchandani, NMIMS, Shirpur : 

Tushar Premchandani 1 INVESTIGATIONAL NEW DRUG (IND)Tushar Premchandani, NMIMS, Shirpur

Introduction : 

2 Tushar Premchandani Introduction An Investigational New Drug Application (IND) is a submission to the Food and Drug Administration requesting permission to initiate a clinical study of a new drug product. The Federal Food, Drug, and Cosmetic Act requires that all drugs have an approved marketing application (NDA, BLA, ANDA) before they can be shipped in interstate commerce.

Introduction : 

3 Tushar Premchandani The IND application allows a company to initiate and conduct clinical studies of their new drug product. The IND application provides the FDA with the data necessary to decide whether the new drug and the proposed clinical trial pose a reasonable risk to the human subjects participating in the study. Introduction

Introduction : 

4 Tushar Premchandani The safety of the clinical trial subjects is always the primary concern of the FDA. In later phases (Phase II and III), the FDA will also evaluate the study design in terms of demonstrating efficacy, but safety of the subjects is critical throughout the drug development process. When preparing an IND, and throughout the drug development process, the primary goal of the sponsor should be to demonstrate to the FDA that the New drug, The proposed trial, and the Entire clinical development plan described in the IND is designed to minimize risk to the trial subjects. Introduction

When Do I Need an IND? : 

5 Tushar Premchandani When Do I Need an IND? An IND is required any time you want to conduct a clinical trial of an unapproved drug The Act further defines a new drug, in part, as “any drug the composition of which is such that such drug is not generally recognized as safe and effective for use under the conditions prescribed, recommended, or suggested in the labeling

When Do I Need an IND? : 

6 Tushar Premchandani 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 a new dosage form. Being administered at a new dosage level. In combination with another drug and the combination is not approved. All clinical studies where a new drug is administered to human subjects, regardless of whether the drug will be commercially developed, require an IND. When Do I Need an IND?

When You Don’t Need an IND? : 

7 Tushar Premchandani When You Don’t Need an IND? An IND is not required to conduct a study if the drug: Is not intended for human subjects, but is intended for in vivo testing or laboratory research animals (non clinical studies) Is an approved drug and the study is within its approved indication for use.

Pre-IND Meeting : 

8 Tushar Premchandani Pre-IND Meeting A meeting between the sponsor and the FDA frequently is useful in resolving questions and issues raised during the preparation for an IND. The FDA encourages such meetings to the extent that They aid in the solution of scientific problems and To the extent that the FDA has available resources.

Pre-IND Meeting : 

9 Tushar Premchandani A pre-IND meeting is considered a Type B meeting. It is a “formal” meeting requiring a written request that includes, A list of specific objectives. Expected outcomes. List of specific questions, grouped by discipline. Pre-IND Meeting

Pre-IND Meeting : 

10 Tushar Premchandani Most issues and questions are usually related to the Design of animal studies needed to initiate clinical trials also The scope and design of the initial study in humans. Type B meetings should be scheduled to occur within 60 days of the FDA’s receipt of the written request for the meeting. Pre-IND Meeting

Pre-IND Meeting : 

11 Tushar Premchandani A briefing document is required at least 4 weeks prior to the meeting. The briefing document should provide summary information relevant to the product and supplementary information that the FDA can use to provide responses to the questions that have been identified by the sponsor for the IND submission. There should be free, full, and open communication about the scientific or medical issue to be discussed during the meeting. The meeting may be a face-to-face meeting or the FDA may prefer to have a telephone conference call to serve as the meeting. Pre-IND Meeting

Pre-IND Meeting : 

12 Tushar Premchandani Usually the attendance at the pre-IND meeting is multidisciplinary, involving the FDA personnel in clinical pharmacology/toxicology, Biopharmaceutics, Chemistry, Statistics, Microbiology, and other disciplines. At the conclusion of the meeting, there should be a review of all the issues, responses, and agreements. An assigned individual from the FDA, usually a project manager, will prepare the minutes of the meeting. Pre-IND Meeting

Pre-IND Meeting : 

13 Tushar Premchandani There are other meetings that can be held during the IND phases of development, including an End of Phase I meeting (generally for fast track products), End of Phase II meeting, and Pre-NDA or pre-BLA meeting. Pre-IND Meeting

The Content and Format of an IND Application : 

16 Tushar Premchandani The form 1571 is a required part of the initial IND and every subsequent submission related to the IND application. The 1571 serves as a cover sheet for IND submissions and provides the FDA Basic information about the submission: Name of the sponsor. IND number. Name of the drug. Type of submission. Serial number, and The contents of the application. The Content and Format of an IND Application

The Content and Format of an IND Application : 

17 Tushar Premchandani It is important to note that the FDA expects every submission, even the most routine correspondence, to be submitted with a completed form 1571 and have a serial number. The FDA tracks all IND submissions based on serial numbers and will file them according to the serial number when received. The Content and Format of an IND Application

The Content and Format of an IND Application : 

18 Tushar Premchandani The 1571 form provides a section for the sponsor to state whether a contract research organization (CRO) will conduct any parts of the study and if any sponsor obligations will be transferred to the CRO. If sponsor responsibilities will be transferred, a list of the obligations transferred and the name and address of the CRO must be attached to the 1571 form. The Content and Format of an IND Application

The Content and Format of an IND Application : 

19 Tushar Premchandani When signing the 1571, the sponsor is also making three important commitments to the FDA The sponsor is committing not to initiate the clinical study until 30days after the FDA receives the IND, unless otherwise notified by the FDA, and not to begin or continue clinical studies covered by the IND if they are placed on clinical hold. The sponsor is committing to ensure that an IRB will be responsible for initial and continuing review and approval of each study The sponsor is committing to conduct the investigation in accordance with all other applicable regulatory requirements. The Content and Format of an IND Application

Institutional Review Board (IRB) : 

20 Tushar Premchandani Institutional Review Board (IRB) A board or committee formally designated by an institution to review and approve the initiation of biomedical research involving human subjects. The primary purpose of the IRB is to protect the rights and welfare of human subjects.

Pharmacology and Toxicology Information — 312.23(a)(8) : 

44 Tushar Premchandani Pharmacology and Toxicology Information — 312.23(a)(8) The decision to proceed to the initial administration of the investigational drug to humans must include the careful conduct and review of the data from nonclinical in vivo and in vitro studies. These data must provide a good level of confidence that the new drug product is reasonably safe for administration to human subjects at the planned dosage levels. The pharmacology and toxicology section of the IND includes the nonclinical safety data that the sponsor generated to conclude that the new drug is reasonably safe for clinical study.

Pharmacology and Toxicology Information — 312.23(a)(8) : 

45 Tushar Premchandani Pharmacology and Toxicology Information — 312.23(a)(8) The amount and type of nonclinical data needed to support a new drug product depends on the Class of the new drug, The duration of the proposed clinical trials and The patient population that will be exposed to the drug.

Pharmacology and Toxicology Information — 312.23(a)(8) : 

46 Tushar Premchandani Pharmacology and Toxicology Information — 312.23(a)(8) The following nonclinical safety studies are required before initiating Phase I studies and the results of these studies must be included in the IND Safety pharmacology studies (often conducted as part of the toxicity studies). Single dose and repeat dose toxicity studies (duration of the repeat dose studies should equal or exceed the duration human clinical trials). Genotoxicity studies (in vitro studies evaluating mutations and chromosomal damage). Reproduction toxicity studies (nonclinical animal studies conducted to reveal any effects the investigational drug may have on mammalian reproduction). Other supplementary studies may be needed if safety concerns are identified.

Previous Human Experience —312.23 (a)(9) : 

47 Tushar Premchandani Previous Human Experience —312.23 (a)(9) This section should contain an integrated summary report of all previous human studies and experiences with the drug.

Relevant Information —312.23(a)(11) : 

49 Tushar Premchandani Relevant Information —312.23(a)(11) Any information specifically requested by the FDA that is needed to review the IND application.

Other Important Information about the Format, Content and Submission of an IND : 

50 Tushar Premchandani Other Important Information about the Format, Content and Submission of an IND For clinical studies that will be submitted as part of an NDA or BLA, IND sponsors must collect financial disclosure information from each investigator or sub investigator who is directly involved in the treatment or evaluation of clinical trial subjects. The sponsor may also reference a drug master file (DMF) in the IND application that contains important information necessary to complete review of the IND. Reports or journal articles in a foreign language must be accompanied by a complete and accurate English translation. Each IND submission must include a four-digit serial number.

Other Important Information about the Format, Content and Submission of an IND : 

51 Tushar Premchandani The FDA requires sponsors to submit the original and two copies of all IND submissions, including the initial IND application and any amendments, correspondence, or reports. The FDA can request that a sponsor submit additional copies of a particular submission at any time. The initial IND and all subsequent submissions more than one page in length should be fully paginated, including all appendices and attachments. Other Important Information about the Format, Content and Submission of an IND

The FDA Review of the IND : 

52 Tushar Premchandani The FDA Review of the IND Once the IND is stamped as received, it is sent to the review division within CDER or CBER Once the IND arrives at the Review Division, it is critically evaluated by several reviewers of Chemistry, Biopharmaceutics, Medical, Statistics, Microbiology and Pharmacology/toxicology sections

The FDA Review of the IND : 

53 Tushar Premchandani All these areas review the data submitted with the primary purpose to ensure appropriate safety of the individuals who will be enrolled in the study Once an IND is submitted, the study cannot be initiated until a period of 30 days has passed If there are any major issues relating to the safety of the volunteers or patients in the proposed study, the FDA can institute a “clinical hold.” The FDA Review of the IND

The FDA Review of the IND : 

54 Tushar Premchandani The FDA Review of the IND A clinical hold may be either a “complete clinical hold” — a delay or suspension of all clinical work requested under an IND, or a “partial clinical hold” — a delay or suspension of only part of the clinical work (e.g., a specific protocol or part of a protocol)

IND Annual Reports : 

55 Tushar Premchandani IND Annual Reports The IND regulations require IND sponsors to submit an annual report that provides the FDA with a brief update on the progress of all investigations included in the IND. The annual report must contain the following information: Individual study information Summary Information The general investigational plan for the coming year. If the investigator brochure was modified during the year, a list of the changes along with a copy of the new brochure.

IND Annual Reports : 

56 Tushar Premchandani A listing of any significant foreign marketing developments with the drug, e.g., approval in another country or withdrawal or suspension of marketing approval. IND Annual Reports

CLASSIFICATION of INDs : 

57 Tushar Premchandani CLASSIFICATION of INDs INDs can be classified on four dimensions: Commercial / Noncommercial, Standard / Emergency, Paper / Electronic, Original / 505(b)(2).

Commercial and Non commercial INDs : 

58 Tushar Premchandani Commercial and Non commercial INDs Commercial INDs (those intended to lead to eventual production and marketing of a drug) are subject to greater scrutiny and review than INDs submitted by universities, research laboratories, and other not - for - profit organizations. For the noncommercial organizations, IND review tends to focus on the study design and the role of the Institutional Review Board (IRB).

Emergency INDs : 

59 Tushar Premchandani Emergency INDs Emergency INDs (often supplements to or amendments of standard INDs) receive priority review and accelerated consideration. As supplements, emergency INDs are generally abbreviated formats referencing the original IND (with a newly filed 1571 form). Most often, they represent corrections or modifications in the experimental design, chemistry, and/or control of the new drug.

Electronic and Paper INDs : 

60 Tushar Premchandani Electronic and Paper INDs Currently, most INDs are submitted in paper form, often accompanied by an electronic disk with hyperlinks. Purely electronic submissions are still rare, in large part because of a lack of standardization and electronic sophistication on the part of the FDA. There is currently a Clinical Data Interchange Standards Consortium (CDISC) test underway. It is likely that CDISC will emerge as a common electronic submission standard for INDs, New Drug Applications (NDAs), and Abbreviated New Drug Applications (ANDAs) over the next three to five years .

Original and 505(b)2 INDs : 

61 Tushar Premchandani Original and 505(b)2 INDs The 505(b)2 provision allows the submission of a IND and supporting submissions (such as an IND application ) in situations in which some or all of the supporting data come from a source or sources outside of the applicant organization. All supporting data come from studies conducted by the applicant (or the applicant ’ s agents) or from studies to which the applicant has right of reference (and access to raw data and analyses)

Original and 505(b)2 INDs : 

62 Tushar Premchandani Original and 505(b)2 INDs Outside sources are generally of two types. Published literature , generally peer reviewed, in which public access to the conclusions, results of analysis, and summary of data Agency findings reporting the FDA ’ s analytical conclusions of drug safety and/or effectiveness. These findings are usually the result of prior review of supporting data related to the drug in question.

The Protocol Amendment : 

63 Tushar Premchandani The Protocol Amendment A protocol amendment is submitted to the FDA when a sponsor wants to initiate a new clinical study that is not described in the existing IND or When the sponsor makes changes to an existing protocol including adding a new investigator to a trial. New protocols are submitted When clinical development of the drug advances to the next phase, e.g., from Phase I to Phase II, or When an additional study is needed during the same phase of development.

The Protocol Amendment : 

64 Tushar Premchandani The Protocol Amendment A protocol amendment for a new protocol must include a copy of the new protocol and a brief description of the most clinically significant differences between the new protocol and previous protocols. When submitting a new protocol to an active IND, the sponsor may initiate the study once the IRB has approved the protocol and it has been submitted to the FDA.

The Protocol Amendment : 

65 Tushar Premchandani The Protocol Amendment A protocol amendment is also required if a sponsor makes significant changes to an existing protocol. For Phase I protocols an amendment is required if the changes may affect the safety of the subjects participating in the study. Other modifications that do not affect the safety of the subjects should be submitted in the IND annual report and not in a protocol amendment.

The Protocol Amendment : 

66 Tushar Premchandani The Protocol Amendment The IND regulations provide the following examples of changes that would require a protocol amendment: An increase in drug dosage or duration of exposure of the subjects to the drug beyond that listed in the current protocol A significant increase in the number of subjects participating in the trial A change in the design of the protocol, such as adding or dropping a control group Adding a new test procedure to monitor for, or reduce the risk of, an adverse event. Eliminating a test intended to monitor safety

The Protocol Amendment : 

67 Tushar Premchandani The Protocol Amendment The IND regulations allow a sponsor to immediately implement a change to a protocol if the change is intended to eliminate an immediate hazard to the clinical trial subjects. A protocol amendment is required when a new investigator or subinvestigator is added to conduct the clinical trial at a new or an existing site.

Information Amendments : 

68 Tushar Premchandani Information Amendments Information amendments are used to submit important information to the IND that is not within the scope of a protocol amendment, annual report, or IND safety report. An information amendment may include New toxicology or pharmacology information, Final study reports for completed nonclinical or other technical studies, New CMC information, Notice of discontinuation of a clinical study, or Any other information important to the IND.
