A change in inclusion/exclusion criteria will require approval from DCGI

Is it necessary to obtain DCGI/EC approval for clinical trial of nutraceutical and register the trial in CTRI? Is it essential to carry out toxicity studies? Binu Kuruvilla DCGI approval is not required unless the indication claim is as per definition of a new drug as per Drugs & Cosmetics Rules.  

The definition of drug is as follows: All medicines for internal or external use of human beings and all substances intended to be used for or in the diagnosis, treatment, mitigation or prevention of any disease or disorder in human beings.

In addition, you should consider new drug definition as per Rule 122E.

A drug is considered a new drug if
1) it is a new chemical, biological or recombinant bio-technological or such devices or delivery systems
2) a drug already approved for certain claims is now being considered for modified or new claims, namely, indications, dosage, dosage form (including sustained release dosage form) and route of administration
3) fixed dose combination of two or more approved drugs, which are now proposed to be combined for the first time in a fixed ratio, or if the ratio of individual drugs already marketed combination is proposed to be changed, with certain claims, viz. indications, dosage, dosage form (including sustained release dosage form) and route of administration EC approval is essential. Registration of clinical trial in CTRI is voluntary. The requirement of toxicity depends on the available human safety data of nutraceutical and duration of the treatment with the nutraceutical in the clinical trial.  

What is the current situation of investigator initiated trials in India - applicable regulations, investigators keenness, funds?  

Shilpi Ray The regulations do not describe investigator initiated trials. However, in light of current MCI Code and CDSCO approach, these are treated like any other trial i.e. investigator IND. If the trial is industry sponsored, it is treated like a typical regulatory approval trial. However, if the trial is an investigator's personal research, requirements are less stringent e.g. a protocol and publication supporting the objectives may suffice. In my experience, very few investigators are keen on such trials. Usually they expect industry to fund and take care of all issues - regulatory/ethics approval etc.  

What is a registry study? Dr Nitin Kulkarni Registry is one approach in Phase IV post-marketing stage. Registries are conducted in a real world setting with the objective of measuring a product’s effectiveness, and are useful in validating the safety and efficacy of interventions seen in controlled clinical trials into everyday practice. The patient registries allow large-scale/long-term data collection without high cost of traditional Phase IV studies. The patient registries also provide an opportunity to collect relevant information relating to interventions, such as: physician experience, patient-reported outcomes, and burden of illness.  

Is BE study of new oncology molecule allowed in Indian patients, if the drug is not available in the Indian market? Is the new liposomal formulation of an old drug considered new medical entity? Is Phase I trial for new formulation of a European sponsor allowed?
Chirag Shah Yes, you can get approval for BE study from DCGI for a new drug. As per Drugs and Cosmetics Act 122 E a new formulation is considered a new drug. If the Phase I is for a new medicinal entity discovered outside India, Phase I will not be allowed.  

If the protocol version is changed due to some minor changes in inclusion and exclusion criteria, do we need DCGI approval or notification is enough?  
Rashmi A change in inclusion/exclusion criteria will require approval from DCGI office. Please see the CDSCO guidance on protocol amendment.
■ Those amendments which do not require notification to or permission of the licensing authority
● Administrative and logistic changes
● Minor protocol amendments and additional safety assessments in case the institutional ethics committee has already approved these changes
● Those amendments which require notification to the licensing authority but need not wait for permission
● Additional investigator sites
● Change in investigator with the consent to withdraw from the earlier investigator
● Amended investigators brochure, amended informed consent
■ Those amendments which require prior permission of the licensing authority
● Additional patients to be recruited
● Major changes in protocol with respect to study design, dose and treatment options
● Any change in inclusion or exclusion criteria.

''Dynamic Indian of the millenium"

As Member Secretary of CLINICOM, I am so thrilled to post this information here:
''Dynamic Indian of the millenium" award conferred

Coimbatore, Jul 4 (PTI) City-based K G Foundation today conferred the 'Dynamic Indian of the Millennium' award on Arun Madhavan, a former member of Prime Minister's special committee for model village development programme under the 20-point programme.

The award, carrying a citation, was given for his 'distinguished achievements and contribution to society over the years', the foundation chairman G Bhakthavatsalam, said at a function got up as part of the celebrations of World Doctors' Day, here.

Besides being conferred a global recognition for his 'project gateway' for promoting India as an investment destination, Arun had delivered a speech at the United Nationas, Geneva, on 'A New dimension to healthcare,' in 1996, he said. The first recipient of this award was the former president, A P J Abdul K…

Isotretinoin in India: A tragedy in the offing

Isotretinoin in India: A tragedy in the offing

Isotretinoin is the drug of choice for severe calcitrant cystic acne vulgaris, which often causes scarring and depression from disfigurement. Isotretinoin has been called "the greatest medical advance of the 1980's." A majority of patients with acne are permanently cleared after a four to five months course of treatment. It has also been used off-label for a variety of oncology uses including: cervical cancer, head and neck cancer, squamous cell cancer of the skin, juvenile chronic myelogenous leukemia (CML), and neuroblastoma. However, the drug is a proved teratogen and carries a significant risk of birth defects, if it taken during pregnancy. Birth defects, which have been documented following isotretinoin exposure include abnormalities of the face, eyes, ears, skull, central nervous system, cardiovascular system, and thymus and parathyroid glands. There is an increased risk …

An important discovery

"Gene therapy strategies will come in with a major cost advantage since DNA interference technology will act at the DNA level at lower doses, reduce toxicity and only one or two copies of the DNA"- Dr Ramanand Nadig

Genes are segments of DNA present in the chromosomes in the nucleus of every cell. Genes carry instructions for making proteins, which are then copied by special enzymes into many copies of messenger RNA (mRNA). The mRNA then comes out of the nucleus, into the body of the cell; where it goes on to create the proteins needed for everyday life. Faulty or mutated genes lead to malfunctioning proteins that cause disease. Gene expression can be blocked by restricting the ability of chromosomal DNA to be copied into RNA and made into proteins. This research has given the lead wherein the ways to correct genetic disease by changing mutant gene sequences to its normal has been …
