Abbreviated new drug application submission
- 1. 1
- 2. An “Abbreviated new drug application”(ANDA) is an application for a U.S. generic drug approval for an existing licensed medication or approved drug. The termed as “abbreviated” because they generally not required to include preclinical (animal) and clinical (human) data to establish safety and effectiveness An ANDA contains data which is submitted to FDA for the review and potential approval of a generic drug product. Once approved, an applicant may manufacture and market the generic drug product to provide a safe, effective, lower cost alternative to the brand-name drug it references. A generic drug product is one that is comparable to an innovator drug product in dosage form, strength, route of administration, quality, performance characteristics, and intended use. Therapeutic Equivalence Evaluations: a drug that has essentially the same effect in the treatment of a disease as one or more other drugs. All approved products, both innovator and generic, are listed in FDA's Approved Drug Products with Therapeutic Equivalence Evaluations. 5/21/2019 DR G.K.SHARMA PHARMD, CPPM, CGCPh, DCMS 2
- 3. generic product performs in the same way as the innovator drug is to measure the time it takes the generic drug to reach the bloodstream in healthy volunteers. This demonstration of “bioequivalence” gives the rate of absorption, or bioavailability, of the generic drug, which can then be compared to that of the innovator drug. To be approved by FDA, the generic version must deliver the same amount of active ingredients into a patient's bloodstream in the same amount of time as the innovator drug. Basic generic drug requirement are:---- 1. Same active ingredient 2. Same route of administration 3. Same dosage form 4. Same strength 5. Same condition of use 6. Inactive ingredient already approved in a similar NDA 5/21/2019 DR G.K.SHARMA PHARMD, CPPM, CGCPh, DCMS 3
- 4. A. Signed FDA form 356h: Provides information regarding– 1. The applicants name & address, 2. Name of the drug product, 3. The product strength 4. Route of administration, 5. Indication of drug master files cited, 6. Proposed indications, 7. A statement regarding whether the product is for prescription or over the counter. B. Index: An index should specify volume & page number for each complete & detailed item. C. Information: Information on the basis for which the ANDA is being submitted. a) Name of the reference drug, its dosage form & strength. b) Information on exclusively for the listed drug. D. Condition for use, including: a) A statement regarding the condition for which the drug will be used. b) A reference to a noted labeling for the product & the currently approved labeling for the listed drug product 5/21/2019 DR G.K.SHARMA PHARMD, CPPM, CGCPh, DCMS 4
- 5. Active ingredient : 1. Reference drug: A statement that is the same active ingredient compare with Reference drug. 2. Combination product: this must be shown for both active ingredients. Statement: This should include a statement that the route of administration, dosage form & strength are same as the reference drug. Bioequivalence: proposed drug is bioequivalent to the listed drug product. Labeling Include a copy of currently approved labeling for the listed drug as well as the proposed labeling for the drug being provided for in the ANDA. A side by side comparison of two sets of labeling is also necessary. Chemistry, Manufacturing & Controls: Describe the composition, manufacture, specifications & analytical procedures for the drug substance & drug product. 1. Human Pharmacokinetics & Bioavailability: This include information concerning 2. The Design 3. The Dosing procedure 4. The number & frequency of blood & urine collection & Methodology for the assay5/21/2019 DR G.K.SHARMA PHARMD, CPPM, CGCPh, DCMS 5
- 6. Samples: The sample of the Drug substance & finished product should be provided four individuals units with sufficient quantities in each unit to permit the FDA to perform all the tests included in the specifications at least three times. Analytical method for drug substance & drug product: This section should consists of the specifications, analytical method, certificates of analysis, method of analysis, method validation & stability indicating data as contained in the chemistry, manufacturing & control part of the application. Labeling: 12 specimen of the final printed label & all labeling for the drug product are to be included. Case report forms & tabulations: The need for these should be discussed with appropriate personnel of the division of bioequivalence prior to submission of the ANDA. 5/21/2019 DR G.K.SHARMA PHARMD, CPPM, CGCPh, DCMS 6
- 7. To reduce the price of the drug. To reduce the time development. Increase the bioavailability of the drug in comparison to references list drug. 5/21/2019 DR G.K.SHARMA PHARMD, CPPM, CGCPh, DCMS 7
- 8. Commonly known as “Drug Price Competition & Patent Term Restoration Act” of 1984. “The Hatch-Waxman Act: is an act dealing with the approval of generic drugs and associated conditions for getting their approval from FDA, market exclusivity, rights of exclusivity, patent term extension and Orange Book Listing.” Established bioequivalence: as the basis for approving generic copies of drug products. These Amendments permit FDA to approve applications to market generic versions of brand- name drugs without repeating costly and duplicative clinical trials to establish safety and efficacy. Under the Hatch-Waxman Amendments, brand-name companies gained patent term extension to account for the time the patented product is under review by FDA and also gained certain periods of marketing exclusivity. In addition to the ANDA approval pathway, generic drug companies gained the ability to challenge patents in court prior to marketing as well as 180-day generic drug exclusivity. 5/21/2019 DR G.K.SHARMA PHARMD, CPPM, CGCPh, DCMS 8

These documents provide guidelines for the content, evaluation, and ultimate approval of applications and also to the design, production, manufacturing, and testing of regulated products for FDA review staff, applicants, and ANDA holders.
