Regulatory Requirement and Approval Procedures for Biologicals and Herbals
Biologicals •Biologics are the products manufactured, extracted from or semi synthesized from a biological source which are regulated by FDA and are used to prevent cure and treat diseases and medical conditions. •These are generally large, complex molecules produced through biotechnology in a living system such as a microorganisms, plant cell or animal cell. •These could be made of sugars, proteins, nucleic acids or complex combinations of these substances or may be living entities. •Examples: Botox, Herceptin, Vaccines, Enbrel
History of Biologicals • Biologics control act 1902 • Authorized hygienic laboratory • In 1934 hygienic laboratory renamed to national institute of health (NIH) • In 1948 divisions of biologics control within national microbiological institute (NMI) • In 1944 BCA incorporated into section 351 of PHSA (CFR title 21 Parts 600-680) • In 1955 salk polio vaccine division of biologics standard (DBS) • In 1972 DBS transferred to FDA as Bureau of biologics • In 1982 BB merged with national center for drugs and biologics (NCDB) • In 1988 NCDB split into 2 centers: CBER and CDER
Sources and Types of Biologics Sources: •Mammalian Cell Culture •Bacteria •Insect Cell Culture •Plant Cell Culture •Yeast •Transgenics •Humans Types: •Blood Derivatives •Vaccines •Allergenic Extracts •Whole Blood •Blood components •Proteins •Human Tissues
Difference b/w biologics & Chemical Drug Properties Biologics Chemical Drug Size Large Small Structure Complex Simple Stability Unstable Stable Modification Impossible to ensure identical copy Identical copy can be made Manufacturing Many options Well defined Characterization Impossible Easy
Regulatory Authority for Biologics •Center for biologics evaluation and research (CBER) is the center within FDA that regulates biological products for human use under applicable Federal laws including the Public health Services Act(PHS) and the Federal, Food, Drug and Cosmetics Act. •CBER protects and advances the public health by ensuring that biological products are safe and effective. •FDA’s regulatory authority for the approval of biologics resides in Act, biologics are subjected to regulation under Federal, Food, Drug and Cosmetics Act. •Some medical devices which are used to produce biologics are regulated by CBER under FD&C Act’s medical device amendments of 1976.
Development and Approval Process •Advertising and labeling •Investigational New Drug Application (IND) or Device Exemption process •Expanded Access •Premarket Approval •Biologics License application (BLA) New Drug Application process (NDA) •Biologics Approvals by Year
Biologics License Application (BLA) •The biologics license application (BLA) is a request for permission introduce or deliver for introduction a biologic product into the market. •It is mainly regulated by 21 CFR 600-800. It is in manufacture or an applicant for a license who takes responsibility for compliance with product and establishment of standards. •A biologic license application generally applies to vaccines and other allergenic drug products and cellular and genetic therapies.
Herbals •Herbal medicines, also known as phytomedicines or botanical medicines, involves the use of plant parts for medicinal/ therapeutic purpose. •It is the oldest and still the most generally used system of medicine in the world at present. The earliest recorded evidence of use of these medicine in India, Chinese, Egyptian, Greek, and Roman texts dates back to about 5000 years. •80% of the world population relies on herbal medicines as their primary healthcare system.

Category 2 : Herbal medicines in systems: Medicines in this category have been used for a long time and are documented with their special theories and concepts, and accepted by the countries. For example, Ayurveda, Unani and Siddha would fall into this category of TM. Category 3 : Modified herbal medicines: These are herbal medicines as described above in categories 1 and 2, except that they have been modified in some way-either shape, or form including dose, dosage form, mode of administration, herbal medicinal ingredients, methods of preparation and medical indications. Category 4 : Imported products with a herbal medicine base: This category covers all imported herbal medicines including raw materials and products. Imported herbal medicines must be registered and marketed in the countries of origin. The safety and efficacy date have to be submitted to the national authority of the importing country and need to meet the requirements of safety and efficacy of regulation of herbal medicines in the recipient country.
Indian Regulations •In India, herbal medicines are regulated under the drug and cosmetic act 1940 and rules 1945, where regulatory provisions for ayurveda, unani, siddha medicine are clearly laid down. Ministry of ayurveda, yoga and naturopathy, unani, siddha and homoeopathy(AYUSH) is the regulatory authority and mandate that any manufacture or marketing of herbal drugs have to be done after obtaining manufacturing license, as applicable. •The main focus of this department is on development of education and research in ayurveda, yoga and naturopathy, unani, siddha and homoeopathy systems. Laws and regulations on herbal medicines are partly the same as those for conventional pharmaceuticals. The D&C Act extends the control over licensing, formulation composition, manufacture, labelling, packing, quality and export. •Schedule T of the act lays down the GMP requirements to be followed for the manufacture of herbal medicines.
Ministry of AYUSH •The Ministry of AYUSH was formed on 9th November 2014 to ensure the optical development and propagation of AYUSH systems of health care. •Earlier it was known as the department of Indian system of medicine and homeopathy which was created in March 1995 and renamed as department of ayurveda, yoga and naturopathy, unani, siddha and homeopathy in November 2003, with focused attention in ayurveda, yoga and naturopathy, unani, siddha and homoeopathy. •In India, manufacturing, marketing, promotion of ASU drugs is controlled by AYUSH. Drug and Cosmetic Act 1940 •Herbal drugs are regulated under the drug and cosmetic act 1940 and rules 1945 in India, where regulatory provisions for ayurveda, unani, siddha medicine are clearly laid down in chapter IV-A. •There are 18 different section are present from section 33C to 33O Table 1. •These all sections provide all information related to ASU drugs regulations for manufacture, sale, registration, GMP certificate, licensing, and penalties.
Schedule T – GMP for Ayurvedic, Siddha and Unani Medicines •In India for getting approval to manufacture or sale of ASU drugs, manufacturer have to take GMP certificate. •According to D and C act rule 157, for getting a certificate of GMP of ASU drugs, the applicant has to file application on a plain paper with full information on existing infrastructure of the manufacturing unit including instruments available, equipment's and technical staff name with qualification. •After full verification by licensing authority as per schedule T requirements licensing authority will issue the certificate within a period of 3 months in form 26-E-I.
New Guidelines for Herbal Medicines •AYUSH providing time to new revised regulations for ASU drugs. Before there is no such guidelines for conducting clinical trials, but in March 2013 AYUSH publish new GCP guidelines for clinical trials in ASU drugs. •GCP is a set of guidelines which incorporates the design, conduct, termination, audit, analysis, reporting and documentation of the studies involving human subjects. •The fundamental tenet of GCP is that in research on man, the interest of science and society should never take precedence over considerations related to the well-being of the study subject. •Its intention to ensure that the studies are scientifically and ethically sound and that the clinical properties of the ASU medicine under investigation are properly documented. •The guidelines seek to establish two cardinal principles: protection of the rights of human subjects and authenticity of ASU medicine clinical trial data generated. •These guidelines are formulated based on CDSCO document on GCP guidelines (2001) for clinical trials on pharmaceutical products. •They should be followed for carrying out all ASU medicine research in India at all stages of drug development, whether prior or subsequent to product registration in India. •These GCP guidelines have to be followed during a clinical trial, if this not follow than clinical trial will be suspended by regulatory authorities. •GCP guidelines also provide the compensation related guidelines for participants if any unwanted result or death of participants occur during clinical trial. •From 2017 onwards, its also mandatory that there must be expiry and manufacturing date present on product label.
