CTD


What is CTD?

The Common Technical Document (CTD) is a set of specification for application dossier, for the registration of Medicines and designed to be used across Europe, Japan and the United States.Quality, Safety and Efficacy information is assembled in a common format through CTD .The CTD is maintained by the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH).


In simple words "CTD is the format for registration of medicines, generally used in EU region, USA and Japan."

Note : CTD format for submission of drug registration applications/dossiers is widely accepted by regulatory authorities of other countries too like Canada, Australia etc. 
The Common Technical Document is divided into five modules:
1. Administrative information and prescribing information
2. Common Technical Document summaries (Overview and summary of modules 3 to 5)
3. Quality 
4. Nonclinical Study Reports (toxicology studies)
5. Clinical Study Reports (clinical studies)
The  Common Technical Document is better understood with a CTD triangle which is  presented below-

The CTD is the mandatory format for new drug applications in the EU and Japan, and the strongly recommended format of choice for NDAs submitted to the FDA. Apart from EU region, USA and Japan, CTD format is widely accepted by many regulatory agencies across the world for registration of Medicines.

 What are the advantages due to the use of CTD?
  • It has revolutionised the regulatory review processes
  • It led to harmonised electronic submission which, in turn, enabled implementation of good review practices
  • For industries, it has eliminated the need to reformat the information for submission to the different ICH regulatory authorities

All the ICH guidelines related to CTD (M4, M4Q, M4S, M4E) are presented below-

M4 Guideline of ICH-  This gives a complete information on the organisation of CTD




In the above guideline to get a complete idea on the sections under each module you need to focus on the content in the page- 5


M4Q Guideline of ICH- This  provides harmonised structure and format for presenting CMC (Chemistry, Manufacturing and Controls) information in a registration dossier.




M4S Guideline of ICHThis provides information on the non-clinical section of application



M4E Guideline of ICH- This provides information on the clinical section of application.

ICH Guidelines


The guidelines of ICH may be broadly categorized into four types-

Quality Guidelines
Safety Guidelines
Efficacy Guidelines
Multidisciplinary Guidelines

Source: ich.org

Quality Guidelines : Harmonisation achievements in the Quality area include pivotal milestones such as the conduct of stability studies, defining relevant thresholds for impurities testing and a more flexible approach to pharmaceutical quality based on Good Manufacturing Practice (GMP) risk management.

Safety Guidelines : ICH has produced a comprehensive set of safety Guidelines to uncover potential risks like carcinogenicity, genotoxicity and reprotoxicity. A recent breakthrough has been a non-clinical testing strategy for assessing the QT interval prolongation liability: the single most important cause of drug withdrawals in recent years.

Efficacy Guidelines : The work carried out by ICH under the Efficacy heading is concerned with the design, conduct, safety and reporting of clinical trials. It also covers novel types of medicines derived from biotechnological processes and the use of pharmacogenetics/genomics techniques to produce better targeted medicines.

Multidisciplinary Guidelines : Those are the cross-cutting topics which do not fit uniquely into one of the Quality, Safety and Efficacy categories. It includes the ICH medical terminology (MedDRA), the Common Technical Document (CTD) and the development of Electronic Standards for the Transfer of Regulatory Information (ESTRI).

ICH


Source: ich.org


What is ICH?
  • ICH is The International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use.
  • It is unique project that brings together the regulatory authorities and pharmaceutical industry of Europe, Japan and the US to discuss scientific and technical aspects of drug registration.
  • It was formed to achieve greater harmonisation in the interpretation and application of technical guidelines and requirements for pharmaceutical product registration in EU, Japan and USA

In Simple words " ICH was formed to have a common scientific and technical requirements for registration of pharmaceuticals in EU, Japan and USA to make the job easy for Regulatory agencies and Pharma companies"

Benefits of Harmonisation/Benefits due to the formation of ICH-

Harmonisation is beneficial to both regulatory authorities and the pharmaceutical industry, ultimately having beneficial impact for the protection of public health. The benefits of harmonization are listed below-

  • Preventing duplication of clinical trials in humans and minimising the use of animal testing without compromising safety and effectiveness.
  • Harmonisation would lead to a more economical use of human, animal and material resources, and the elimination of unnecessary delay in the global development and availability of new medicines while maintaining safeguards on quality, safety, and efficacy, and regulatory obligations to protect public health
  • Streamlining the regulatory assessment process for new drug applications; and reducing the development times and resources for drug development.

Origin Of ICH-
  • Harmonisation of regulatory requirements was pioneered by the European Community (EC), in the 1980s, as the EC (now the European Union) moved towards the development of a single market for pharmaceuticals. The success achieved in Europe demonstrated that harmonisation was feasible.
  • At the same time there were bilateral discussions between Europe, Japan and the US on possibilities for harmonisation. 
  • It was, however, at the WHO Conference of Drug Regulatory Authorities (ICDRA), in Paris, in 1989, that specific plans for action began to materialize.
  • Soon afterwards, the authorities approached IFPMA to discuss a joint regulatory-industry initiative on international harmonisation, and ICH was conceived.
  • The birth of ICH took place at a meeting in April 1990, hosted by EFPIA in Brussels. Representatives of the regulatory agencies and industry associations of Europe, Japan and the US met, primarily, to plan an International Conference but the meeting also discussed the wider implications and terms of reference of ICH.
  • At the first ICH Steering Committee (SC) meeting of ICH the Terms of Reference were agreed and it was decided that the Topics selected for harmonisation would be divided into Safety, Quality and Efficacy to reflect the three criteria which are the basis for approving and authorising new medicinal products.

ICH Secretariat-
ICH does not have "offices" as such, but ICH secretariat is based in Geneva, Switzerland. The biannual meetings and conferences of the ICH Steering Committee rotate between the EU, Japan, and the USA.

Process of Harmonisation:

ICH harmonisation activities fall into 4 categories: Formal ICH Procedure, Q&A Procedure, Revision Procedure and Maintenance Procedure, depending on the activity to be undertaken (see below).

Formal ICH Procedure for new topic of harmonisation :

The Formal ICH Procedure is a step-wise procedure consisting of 5 steps .This procedure is followed for the harmonisation of all new ICH topics



ICH guidelines have been adopted as law in several countries, but are only used as guidance for the U.S. Food and Drug Administration

Finally, I would like to end with a beautiful quote by Henry ford  "Coming together is a beginning. Keeping together is progress. Working together is success"


P.S. 
1. Explanation of Abbreviations quoted in the above post-
(i)MedDRA or Medical Dictionary for Regulatory Activities is a clinically validated international medical terminology used by regulatory authorities and the regulated biopharmaceutical industry throughout the entire regulatory process, from pre-marketing to post-marketing activities, and for data entry, retrieval, evaluation, and presentation.
(ii)
Q-Quality
S-Safety
E-Efficacy
M-Multidisciplinary
(iii)Q3C is - Impurities :Guideline for Residual Solvents
(iv) M2   is -Multi-disciplinary Group 2

AUTHORIZATION TO REFER TO A DRUG MASTER FILE

Before FDA can review DMF information in support of an application, the DMF holder must submit in duplicate to the DMF a letter of authorization permitting FDA to reference the DMF

The letter of authorization (LOA) should include the following:

The date.
Name of DMF holder.
DMF number.
Name of person(s) authorized to incorporate information in the DMF by reference.
Specific product(s) covered by the DMF.
Submission date(s) of 5, above.
Section numbers and/or page numbers to be referenced.
Statement of commitment that the DMF is current and that the DMF holder will comply with the statements made in it.
Signature of authorizing official.
Typed name and title of official authorizing reference to the DMF.

The holder of DMF should send a copy of LOA to affected applicant, sponsor or other holder who is authorized to incorporate information contained in the DMF. The copy of LOA issued by DMF holder should be included in the application by applicant, sponsor or holder referencing the DMF.

Format and Content of DMF

DMFs may be submitted following the format recommended in the "Guidance for Industry  M4Q: The CTD - Quality".

Incomplete submission

If the submission is administratively incomplete or inadequate, it will be returned to the submitter with a letter of explanation from the Drug Master File Staff, and it will not be assigned a DMF number.

DMF review
  •  An original DMF submission will be examined on receipt to determine whether it meets minimum requirements for format and content. If the submission is administratively acceptable, FDA will acknowledge its receipt and assign it a DMF number.
  •  The agency will review information in a DMF only when an IND sponsor, an applicant for an NDA, ANDA, or Export Application, or another DMF holder incorporates material in the DMF by reference.                  
  •   If FDA reviewers find deficiencies in the information provided in a DMF, a letter describing the deficiencies is sent to the DMF holder and also the person who relies on the information in the deficient DMF (However, only general subject of deficiency is revealed to the applicant/person referring information in DMF)
  • When the holder submits the requested information to the DMF in response to the agency's deficiency letter, the holder should also send a copy of the accompanying transmittal letter to the affected persons relying on the DMF and to the FDA reviewing division that identified the deficiencies. The transmittal letter will provide notice that the deficiencies have been addressed.

Holder Obligations

Any change or addition, including a change in authorization related to specific customers, should be submitted in duplicate and adequately cross referenced to previous submission(s). The reference should include the date(s), volume(s), section(s), and/or page number(s) affected.

Notice Required for Changes to a Drug Master File

A holder must notify each affected applicant or sponsor who has referenced its DMF of any pertinent change in the DMF . Notice should be provided well before making the change in order to permit the sponsor/applicant to supplement or amend any affected application(s) as needed.

Listing of Persons Authorized To Refer to a Drug Master File
  • A DMF is required to contain a complete list of persons authorized to incorporate information in the DMF by reference. The holder should update the list in the annual report.
  • The updated list should contain the holder's name, DMF number, and the date of the update.
  • The update should identify by name (or code) the information that each person is authorized to incorporate and give the location of that information by date, volume, and page number.
  • Any person whose authorization has been withdrawn during the previous year should be identified under a suitable caption.

 Annual Report
  •  The holder should provide an annual report on the anniversary date of the original submission. This report should contain complete list of authorized persons persons referring the DMF and should also identify all changes and additional information incorporated into the DMF since the previous annual report on the subject matter of the DMF. If the subject matter of the DMF is unchanged, the DMF holder should provide a statement that the subject matter of the DMF is current.
  •  Failure to update or to assure FDA annually that previously submitted material and lists in the DMF remain current can cause delays in FDA review of a pending IND, NDA, ANDA, Export Application, or any amendment or supplement to such application; and FDA can initiate procedures for closure of the DMF.


 Appointment of an Agent

Domestic DMF holders do not need to appoint an agent or representative, although foreign DMF holders are encouraged to engage a U.S. agent.When an agent is appointed, the holder should submit a signed letter of appointment to the DMF giving the agent's name, address, and scope of responsibility (administrative and/or scientific). 

Transfer of Ownership

To transfer ownership of a DMF to another party, the holder should so notify FDA and authorized persons in writing. The letter should include the following:

Name of transferee
Address of transferee
Name of responsible official of transferee
Effective date of transfer
Signature of the transferring official
Typewritten name and title of the transferring official.

The new holder should submit a letter of acceptance of the transfer and an update of the information contained in the DMF, where appropriate. Any change relating to the new ownership (e.g., plant location and methods) should be included.


MAJOR REORGANIZATION OF A DRUG MASTER FILE

A holder who plans a major reorganization of a DMF is encouraged to submit a detailed plan of the proposed changes and request its review by the Drug Master File Staff. The staff should be given sufficient time to comment and provide suggestions before a major reorganization is undertaken.


CLOSURE OF A DRUG MASTER FILE
  • A holder who wishes to close a DMF should submit a request to the Drug Master File Staff stating the reason for the closure. 
  • The request should include a statement that the holder's obligations  have been fulfilled.
  • The Agency may close a DMF that does not contain an annual update of persons authorized to incorporate information in the DMF by reference and a list of changes made since the previous annual report. The holder will be notified of FDA's intent to close the DMF.
