AIM
 The aim of my project work is to file an IND
for the drug product in Electronic Common
Technical Document (eCTD) format for USA
in accordance with recent regulatory changes
stipulated in draft guidelines published by
FDA on January 2013.
2

OBJECTIVES
PRIMARY OBJECTIVE:
 The prime motto of this project is to attain a great insight
into the guidelines regarding the eCTD submissions and
filing an IND to US FDA in eCTD format for a drug.
SECONDARY OBJECTIVE:
 Making out the difference between traditional IND and
eCTD (version 3.2.2) format and stating the importance and
benefits of filing a submission in eCTD format.
 To collect(CMC, Non Clinical, Clinical literature, etc...),
analyse, organize the data and prepare an IND in eCTD
format.
3

SCOPE
 The draft guidance “Guidance for Industry Providing
Regulatory Submissions in Electronic Format- Certain
Human Pharmaceutical Product Applications and
Related Submissions Using the eCTD Specifications”
published by US FDA in January 2013 stated that, the
regulatory submission to FDA has to submitted in eCTD
format for their review and approvals.
 The FD&C Act provides that the submissions shall be
submitted in electronic format “beginning to earlier than 24
months after the issuance of a [final guidance specifying the
format for such submissions]”.section 745(A). Therefore, the
electronic submission requirement will be phased in
according to the following schedule: 4

SCOPE
 (1) 24 months after publication of final version of this
draft revised guidance, the requirements will apply to
NDA, ANDA, and BLA submissions.
 (2) 36 months after publication of the final guidance, the
requirements will apply to IND submissions.
As IND’s has to be submitted in eCTD format from the
year of 2016 I felt this as one important emerging topic
and has chosen it as my project. I felt that carrying out
project on such emerging topics would fetch me great
opportunities in the field of regulatory affairs.

INTRODUCTION
INVESTIGATIONAL NEW DRUG APPLICATION
(IND)
 An Investigational New Drug Application (IND) is a request for
Food and Drug Administration (FDA) authorization to
administer an investigational drug to humans. Such authorization
must be secured prior to interstate shipment and administration
of any new drug that is not the subject of an approved new drug
application. IND regulations are contained in Title 21, Code of
Federal Regulations, Part 312.
6

Types of IND
 Investigator 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 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.
 Emergency Use IND
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 21 CFR, 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.
7

 Treatment IND
Treatment IND is submitted for experimental drugs 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:
 Commercial
 Research(non-commercial)
And my project is a commercial treatment IND.

BACKGROUND
CTD (COMMON TECHNICAL DOCUMENT)
 ICH is a joint initiative involving both regulators and industry as
equal partners in the scientific and technical discussions of the
testing procedures which are required to ensure and assess the
safety, quality and efficacy of medicines.
 The CTD was agreed upon in November 2000, in San Diego, USA. The
purpose of this Common Technical Document (CTD) is to provide a
harmonised structure and format for new product applications (marketing
authorization).
9

CTD (COMMON TECHNICALDOCUMENT)
 The focus of the CTD is to provide a common format for the preparation of a
well structured submission according to the modular framework described in
the ICH guidelines of the Common technical document for registration for
Human Use (ICH topic M4).
 The agreement to assemble all the Quality, Safety and Efficacy information in
a common format (called CTD - Common Technical Document ) has
revolutionised the regulatory review processes, led to harmonised electronic
submission that, 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.
10

CTD (COMMON TECHNICALDOCUMENT)
 The CTD guidance indicates where and how available information is to be
presented.

ELECTRONIC COMMON TECHNICALDOCUMENT
(eCTD)
 The ICH M2 Expert Working Group (EWG) has defined, eCTD as
an interface for industry to agency transfer of regulatory information
while at the same time taking into consideration the facilitation of the
creation, review, lifecycle management and archival of the electronic
submission. The eCTD specification lists the criteria that will make
an electronic submission technically valid. The focus of the
specification is to provide the ability to transfer the registration
application electronically from industry to a regulatory authority.
Industry to industry and agency to agency transfer is not addressed.
 ICH multidisciplinary guideline 2, Electronic Standards.
14

XML(Extensible Markup Language) Based
eCTD
 The XML eCTD DTD (Document Type Definition) defines the overall structure of
the submission. The purpose of the XML backbone is two-fold: (1) to manage meta-
data for the entire submission and each document within the submission and (2) to
constitute a comprehensive table of contents and provide corresponding navigation
aids. Meta-data on submission level include information about submitting and
receiving organization, manufacturer, publisher, ID and kind of the submission, and
related data items.
 Examples for meta-data on document level are versioning information, language,
descriptive information such as document names and checksums.
 Extensible Markup Language (XML) is a markup language that defines a set of
rules for encoding documents in a format that is both human-readable and machine-
readable.
15

eCTD (electronic CTD) Submission
 An eCTD submission is a collection of data objects that follows the
eCTD specification. The main function of the eCTD submission is
data exchange. Information systems would have to be created to
process the eCTD submission. The biggest benefits are expected
when the eCTD submission is loaded into an information system that
supports the review process. However, one can view an eCTD
submission with a Web browser as it is Web ready. In the Web
environment, the eCTD submission should be usable without
processing in at least in the following ways:
 Standalone: Viewable with a Web browser.
 Network: Loadable into a Web server

RIOCIGUAT Tablets
Description:
 Riociguat is a tablet for oral administration. Riociguat is methyl
4,6-diamino-2-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-
3-yl]-5-pyrimidinyl(methyl)carbamate with the following
structural formula
Druginformation
 The solubility at 25°C in water: 4 mg/L,
in ethanol: 800 mg/L, in 0.1 HCl (pH 1):
250 mg/L and in buffer (phosphate) pH 7:
3 mg/L. In the pH range of 2 to 4 the
solubility showed strong pH-dependency.
Solubility increases at lower pH values.
17

 Riociguat is a soluble guanylate cyclase (sGC) stimulator indicated for
the treatment of adults with :
 Persistent/recurrent Chronic Thromboembolic Pulmonary
Hypertension (CTEPH) (WHO Group 4) after surgical treatment or
inoperable CTEPH to improve exercise capacity and WHO functional
class.
 Pulmonary Arterial Hypertension (Riociguat is a white to yellowish,
crystalline, non-hygroscopic substance with a molecular weight of
422.42 g/mol. In solid form it is stable to temperature, light, and
humidity.
 PAH) (WHO Group 1) to improve exercise capacity, improve WHO
functional class and to delay clinical worsening.
18

Soluble guanylate cyclase
 Vasodilatator
 Synthetised by NO synthase in endothelial and epithelial cells
 Inhaled treatments with NO are unsuitable as long term therapies for PH
due to: short life, development of tolerance, non specific interactions with
biomolecules
 Toxicity with high dose
20
Nitric oxide
 Heterodimer: larger α subunit and a smaller haem-binding β subunit
 Prosthetic haem moiety on the haem binding domain with a reduced Fe2+
 GTP cGMP

Generalinvestigationalplan
 Research Rationale and Objectives
 Pulmonary hypertension is defined as an increase in mean pulmonary
arterial pressure (mPAP) >25 mmHg at rest as assessed by right heart
catheterization. This clinical definition includes a group of diseases that
share symptoms of dyspnea, fatigue, and reduced exercise capacity.
 Both CTEPH and PAH are characterized by increased mPAP associated with
pulmonary vascular resistance (PVR), which can lead to progressive right
ventricular dysfunction/failure, and ultimately, premature death. Based on
the pathophysiology, the pharmacologic activity of riociguat was expected
to result in beneficial clinical effects in both CTEPH and PAH.
29

 Proposed Clinical Research
 Relative Bioavailability and Food Effect Study of Two Oral Liquid
Formulations in Comparison to a 1mg Tablet of Riociguat to
Characterize Its Pharmacokinetic Properties in Healthy Male and Female
Adult Subjects in a Randomized, Open Label, 5 Fold Crossover Design.

Managing IND Application

Submission Process
Pre-Filing Phase
55

Managing INDApplication
The pre-filing phase :
 key activity is the collection of all reports which will need to be filed with the IND
 Pre-IND meetings can be held either as face-to-face meetings or by teleconference.
 The principal aim of the pre-IND meeting is to avoid any judgements by the FDA
which would preclude the conduct of the clinical trial, or might result in a clinical
hold on review of the IND. By familiarising the FDA with your drug and your
intended clinical plans, you are trying to ensure a clear path to the clearance of your
IND.
Submission Process:
 one month prior to submission data is strongly advised.
 a surprise submission will not help with building your relationship with the project
manager.
56

Managing INDApplication
Review Process:
 The comments to the IND come in two categories.
 forward-looking comments and recommendations.
 comments which are “Clinical Hold” issues
Even if there is no approval letter, the FDA will issue a written summary of the suggestions,
comments, and requirements for the study to proceed within the next 4-7 working days.
Maintenance Phase:
 IND must be maintained over time by filing, at a minimum, Annual Reports to the IND. The
purpose of the Annual Report is inform the FDA of the drug’s progress in development;
however even if there has been no progress, an Annual Report to the IND must be filed in
order to keep the IND open. If the IND is not maintained, then the FDA will eventually
terminate the IND. If the IND is terminated and drug development starts again, then the entire
IND would have to be refiled.
57

IND Format
 The format of an IND can take multiple shapes: from a submission in
eCTD format to a paper submission in traditional format or a mixture
thereof can be acceptable. The granularity of traditional format is guided
by 21CFR312.23(a)-(f) (termed “Items” 1-8) which need to be authored
for IND. Item 1 (Cover letter; FDA Form 1571), Item 2 (Table of
Contents), Item 3 (Introductory Statement), and Item 4 (General
Investigational Plan), are unique to an IND. Item 5 (Investigator’s
Brochure), Item 6 (Protocol), Item 7 (Chemistry, Manufacturing, and
Control [CMC] Information) and Item 8 (Pharmacology and Toxicology
Information) can be reused in other regulatory submissions if appropriately
structured. A common hybrid IND submission type presents Item 7 in
CTD granularity under 3.2.S for Drug Substance and 3.2.P for Drug
Product and consists of eight principal sections ;

Comparison between NeeS and eCTD in a Dossier
Format
NeeS eCTD
More often handled as individual dossiers Standard across industry
Can be viewed in EURS Typically viewed via viewing tool
Validation rules all category
A – potential to automate
Can see what has changed when
No lifecycle, no metadata Contains metadata, application history
Heavily reliant on file/folder structure Tool can be deployed throughout
organisation
64

NeeS vs. eCTD in terms of Software
NeeS eCTD
All software required already on desktop or
easilydeployable
Need specialist software
Can quickly adapt your organisation to build
and validate NeeS (including affiliates)
Deployment centrally only – or at all offices
dealing with dossiers
No need for expensive corporate wide
enterprise system
Potentially complex IT architecture and
performance issues
–Connectivity, access to content
–Re-use of content
–Resource availability
–Training
No additional software costs Expensive
65

discussionandConclusion(cont..)
Advantages of the eCTD format:
 Suitable for managing CMC dossiers for other regions through
customized CMC document creation and for building CMC
dossier content progressively over time.
 Can be used for all phases of development
 Allows consistent authorising practices for both investigational
and marketing dossiers.
 Bookmarks and headings, because of ICH restrictions on levels,
can cover more subtopic in a more granular document approach
rather than a single document covering many topics.
 Mistakes are easily addressed without subjecting old content to
re-review by the Agency
 More advantageous in maintaining the life cycle management.
66

Conclusion
 The purpose of my thesis is to provide helpful considerations in
developing a company strategy for submitting the IND information in
eCTD format. Since there are no official guidelines for eCTD INDs,
my thesis provides options derived from guidance’s to help
companies determine how to organize and present IND information
using the principles of the eCTD format.
 Since, most companies conduct clinical trials globally, this option of
IND in eCTD format provides opportunities to avoid reworking the
same information into multiple different formats for clinical trial
