3 Indian Council of Medical Research (ICMR)
The apex body in India for the formulation, coordination and promotion of biomedical research under Department of Health Research, Ministry of Health and Family Welfare, Government of India Established in 1911, as Indian Research Fund Association (IRFA) Re-designated in 1949 as the Indian Council of Medical Research (ICMR) with considerably expanded scope of functions. Intramural research is carried out through the Council's theme oriented 33 permanent research institutes/centers and including 6 regional centers addressing to regional health problems Extramural research is done through center for advanced research, task force projects, ad hoc research schemes and fellowships in different universities, medical colleges in the country.

4 The Mandate of ICMR To undertake and support basic, epidemiological, applied and operational research in the areas of national public health importance using tools including those of modern biology.

5 Thrust Areas Fundamental Strategic Product development and evaluation
Operational Research Communicable diseases Non-communicable diseases Reproductive health Nutrition Basic sciences Medicinal plants, Traditional Medicine Ethics, IPR, socio-behaviour sciences

6 Clinical Trial Regulated under Schedule Y of Drugs and Cosmetic Act 1940
Human clinical trials are conducted To demonstrate the efficacy and safety of a new drug To explore new indication, New route of administration New combination of old drugs. Clinical trials form the basis for therapeutic decisions by all physicians, therefore, it is essential that they be able to evaluate the results and conclusions of such trials critically.

7 New Drug Development Clinical Evaluation-Good Clinical Practices
Phase I (Safety / tolerance) Pharmacokinetic-Healthy volunteers/exceptions Phase II (Efficacy and dose range studies conducted on patients) Phase III (Clinical trials on large number of patients) Phase IV (Post marketing surveillance)

8 Need for Clinical Trials Registry
Clinical trials hold enormous potential for benefiting patients, improving therapeutic regimens and ensuring advancement in medical practice that is evidence based. Unfortunately, the data and reports of various trials are often difficult to find and in some cases do not even exist as many trials abandoned or are not published due to "negative" or equivocal results. However, this tendency for availability of only selective information from the myriad clinical trials conducted is not commensurate with the practice of "evidence-based medicine“. Today, world over, a need has been felt on the imperative for transparency, accountability and accessibility in order to re-establish public trust in clinical trial data. And this would be feasible only if all clinical trials conducted are registered in a centralized clinical trials registry. Registration of trials will ensure transparency, accountability and accessibility of clinical trials

9 Interactive workshop on Building and managing clinical trial capacity in India : Challenges in Ethics, Equity and Efficiency held on October 21-22, 2005 Recommendations A registry for all Clinical trials should be created with multiple stakeholders be part of the design process of such a registry for it to be meaningful. Such a registry should have a public and a confidential element. Some key items may need to be blocked from the public view (such as raw data pertaining to SAEs and proprietary information) but necessary for regulatory enforcement purposes and scientific research

10 Clinical Trials Registry

11 Clinical Trials Registry-India (CTRI) launched on 20th July,2007

12 Clinical Trials Registry of India
The Clinical Trials Registry- India (CTRI), hosted at the ICMR’s National Institute of Medical Statistics (NIMS), is a free and online public record system for registration of clinical trials being conducted in India that was launched on 20th July 2007 ( Initiated as a voluntary measure, since 15th June 2009, trial registration in the CTRI has been made mandatory by the Drugs Controller General (India) (DCGI) ( Moreover, Editors of Biomedical Journals of 11 major journals of India declared that only registered trials would be considered for publication1, 2.

13 Clinical Trials Registry of India
Multi-country trials, where India is a participating country, which have been registered in an international registry, are also expected to be registered in the CTRI. In the CTRI, details of Indian investigators, trial sites, Indian target sample size and date of enrollment are captured.

14 Mission and Vision Mission Vision
Encourage all clinical trials to be prospectively registered before enrolment of first patient To comply with ICMJE and WHO-ICTRP requirements Vision To ensure that every clinical trial conducted in the region is prospectively registered with full disclosure of the trial data set items. While this register is meant primarily for trials conducted in India, the CTRI will also accept registration of trials conducted in other countries in the region, which do not have a Primary Registry of its own. To improve transparency To improve internal validity of trials Conform to accepted ethical standards Reporting of all relevant results of registered trials 14

15 Objectives To establish a public record system by registering all clinical trials on health products that are drugs, devices, vaccines, herbal drugs and made available to both public and healthcare professionals in an unbiased, scientific and timely manner To create a more complete, authentic, and readily available data of all ongoing and completed clinical trials Increase awareness and accountability of all the participants of the clinical trials and also for public access. 15

16 Features of Registry Web based access from any computer with internet connectivity Scalable to cover more countries Designed and developed on Open Technologies Three levels of Access User (Authorized to submit Trials) Administrator (Responsible for administering the Registry) Public (Facility to search information) 16

17 Features of Registry The information collected is available to the general public at no cost. The Registry would be a searchable Primary register, which is to be linked to the WHO’s ICTRP. Registration is voluntary To register a study, trialists need to submit information on the Data Set items before enrolment of the first patient 17

18 Trial Registration Criteria
All interventional clinical trials conducted in India and involving Indian participants need to be registered. An interventional clinical trial is any research study that prospectively assigns people to one or more health-related interventions to evaluate their effects on health-related outcomes. Examples include but are not limited to: Preventive care, Drugs (including herbal), Surgical procedures, Behavioral treatments, Medical devices etc. Thus, early and late trials, trials of marketed or non-marketed products, randomized or non-randomized trials -- all should be registered. If in doubt about whether to register or not, registration is recommended. 18

20 Trial Registration Requirements
Some fields are mandatory for registration to proceed. All WHO fields [marked] need to be completed if the trial is to receive a registration number and fulfill WHO/ICMJE requirements. Both date of submission and date of registration are recorded. Trialists are encouraged to include subsequent protocol amendments and give regular updates on the status of trial. All amendments and original entries will be recorded (audit trail) 20

21 Challenges Voluntary – ensuring compliance
Improving quality of clinical trials Scaling up Sustainability Of the 65 journals selected,38 mentioned the ICMJE requirements in their instructions to authors but only 20 required authors to submit manuscripts in accordance with consort guidelines. Prospective registration in CTRI that requires items pertaining to internal validity and ethical conduct can improve the design, conduct of clinical trials. 21


23 National Medical Research Database

24 Clinical Research Database
A Clinical Research Database is a tool used as part of the data collection process. A database allows you to store your research data collected in the field in an organized fashion so that it can be easily analyzed in statistical programs. The steps involve the initial process of collecting corresponding clinical information in a database

25 National Medical Research Database ICMR initiative : Commissioning National Centre for Disease Informatics (NCDIR), Bangalore in March 2011 The new centre was the outcome of the sustained and successful run of the National Cancer Registry Programme since December 1981. The main objective of the NCDIR is To sustain and develop a national research data-base on cancer, diabetes, CVD and stroke through recent advances in electronic information technology with a national collaborative network, so as to undertake aetiological, epidemiological, clinical and control research in these areas.

26 National Centre for Disease Informatics (NCDIR)
Current thrust areas of NCDIR: Cancer Registries - National Cancer Registry Programme (NCRP) Patterns of Cancer Patient Care and Survival Development of Software Applications Programmes The NCRP, as of now, has a network of - 27 population based, - 9 hospital based cancer registries and - 17 centres collaborating in the study on Patterns of Care and Survival Studies

27 National Centre for Disease Informatics (NCDIR)
Major achievements Collection of disease data in a systematic way providing actual incidence (not estimates) as per international standards and quoted. Sustained programme for over 25 years providing valid estimates of the burden and patterns of cancer. The cancer atlas project helped map patterns of cancer in a cost effective way using recent advances in Electronic Information Technology. This gave a new concept in data collection and broadened the field of disease informatics. It identified many researchable areas; motivated pathologists and clinical oncologists across country to collaborate and participate in cancer research; with minimum effort provided critical base line information at district level. Finally it opened the entire North Eastern states for cancer registration and research

28 Other contributions of NCDIR
Overall the contributions of the NCRP are the following: Towards Epidemiological and other Research Identification of geographic areas for site specific research; Identification of variation in sites of tobacco related cancers vis-à-vis geographic areas; laid a foundation for studies in molecular epidemiology Towards Cancer Control Identified especially through the cancer atlas different sites for priority towards cancer control; Provide an idea of the magnitude and trends over time in different sites of cancer; Provided information for doing evidence based cancer control activities through specific indicators.

29 Other contributions of NCDIR
Towards Patient Care Identification of deficiencies in cancer patient care in the Indian setting in terms of standardised recording of clinical information, compliance to treatment and follow-up; Identification of proportion of patients presenting at late stage; Laid a framework towards clinical evaluation and multi-centric trials. The NCRP through its network of cancer registries has several national and international publications in Descriptive and Analytical Epidemiology that are of national relevance and importance.
