Satish Mallya January 20-22, |3 | TRS970 Annex 4 Overarching Principles: –The Pharmaceutical development section should contain information on the development studies conducted to establish that the dosage form, the formulation, manufacturing process, container-closure system, microbiological attributes and usage instructions are appropriate for the purpose specified in the product dossier. –Additionally, this section should identify and describe the formulation and process attributes (critical parameters) that can influence batch reproducibility, product performance and FPP quality.

Satish Mallya January 20-22, |6 | QTPP & CQA QTPP: A prospective summary of the quality characteristics of a drug product that ideally will be achieved to ensure the desired quality, taking into account safety and efficacy of the drug product. CQA: A physical, chemical, biological or microbiological property or characteristic that should be within an appropriate limit, range, or distribution to ensure the desired product quality.

Satish Mallya January 20-22, |9 | CQAs of the API & Excipients Key physicochemical characteristics of the API that can influence the performance of the FPP: –Physical properties: particle size distribution, bulk and tap densities, crystalline form, hygroscopicity, solubility ; –Chemical properties: stability under temperature, humidity, oxidative, photolytic conditions –Biological properties: permeability, partition coefficient, BCS The compatibility of the API(s) with each other (FDCs) and with excipients; The choice of excipients, their concentration and their characteristics that can influence the FPP performance.

Satish Mallya January 20-22, | Manufacturing Process Development Justification for the selection of the manufacturing process and in-process controls; –Appropriateness of the equipment used; –Identification of critical process parameters (CPP) Justification for differences between the manufacturing processes used to produce batches for bioequivalence studies or primary stability studies and the commercial process. May 18-21,2014

Satish Mallya January 20-22, | Critical Process Parameter (CPP) A process parameter whose variability has an impact on a critical quality attribute (CQA) and therefore should be monitored or controlled to ensure the process produces the desired quality –Blending –Granulation –Drying (LOD) –Compression –Coating May 18-21,2014

Satish Mallya January 20-22, | Other Considerations Justification for overages Issues surrounding score line - uniformity testing (i.e. Content uniformity for split portions containing less than 5 mg or less than 5% of the weight of the dosage unit portion, or mass uniformity for other situations) should be performed on each split portion from a minimum of 10 randomly selected whole tablets. In-vitro dissolution –Development of discriminatory method –Generation of dissolution profiles Optimization and Scale-up May 18-21,2014

Satish Mallya January 20-22, | Optimization Studies Studies are undertaken to optimize: –quantity of binder –quantity of disintegrant –LOD Different trial batches having varying amounts of disintegrant and binder are used; Results of granule flowability, tablet characteristics and comparative dissolution profiles are compared; Granules with different LOD levels are compressed and results with respect to flowability and tablet characteristics are used to finalize formulation; The formulation so developed is considered to be optimized when there are no problems (e.g. capping) and the dissolution profile matches the innovator product May 18-21,2014

Satish Mallya January 20-22, | Case Study #2 Applicant has developed an IR tablet product containing light and moisture sensitive API. The API belongs to BCS class 2 and exists in 2 polymorphic forms. The API constitutes 4% of the formulation.
