PDA Technical Glossary

A series of tests designed to increase process knowledge by examining proposed operational ranges and their individual and/or combined impact on the chromatography process. (TR14) A late-stage study that evaluates the process to increase process knowledge and examines proposed operational ranges and their individual and/or combined impact on target protein quality. (TR42)

A pre-determined number of production lots, typically three, that represent the process and are evaluated to demonstrate consistency. [Synonyms: validation, consistency, demonstration lots, qualification lots] (TR14) (TR42)

Documentation and description of work done during the early phases of development. The goal is to document information about the way the process works and to document why key choices were made in selecting the specifics of the process (e.g., flow rate or temperature). These documents can serve as a reference during investigations of discrepancies and during the design of specific Validation and characterization studies.(TR14) (TR 42) Documentation and description of work done during the early phases of development (Stage 1). The goal is to document information about the way the process works and to document why key choices were made in selecting the specifics of the process (e.g., flow rate or temperature). These documents can serve as a reference during investigations of deviations and during the design of specific validation and process characterization studies.(TR60)

A pharmaceutical product type that contains a drug substance, generally, in association with excipients. [Synonym: Dosage Form; Finished Product] (TR57)(TR14)(TR42) A finished dosage form (e.g., tablet, capsule, or solution) that contains a drug substance, generally, but not necessarily, in association with one or more other ingredients.(TR38) (TR67) (TR88) The dosage form in the final immediate packaging intended for marketing.(TR60)(TR82)

Documented verification that the equipment or systems, as installed or modified, comply with the approved design, the manufacturer’s recommendations, and/or user requirements. (TR14) (TR42) (TR48) (TR61) (TR64) The documented verification that the facilities, systems and equipment, as installed or modified, comply with the approved design and the manu­facturer’s recommendations. (TR54-5) Documented verification that the equipment or systems, as installed or modified, comply with the approved design, the manufacturer’s recommendations, and/or user requirements (17). (TR60)

Documented verification that the equipment and ancillary systems, as connected together, can perform effectively and reproducibly based on the approved process method and specifications. (TR3) (TR14) (TR45) (TR42) (TR48) (TR61) (TR64) Transport tests of product or representative product that is conducted during actual transportation or distribution. (TR39) Documented evidence that provides a high de­gree of assurance that the equipment and/or system functions accurately and consistently according to predetermined specifications in its operating environment. (TR54-5) Documented verification that the equipment and ancillary systems, as connected together, can perform effectively and reproducibly based on the approved process method and specifications (17). (TR60-3)

The documented evidence that the process, operated within established parameters, can perform effectively and reproducibly to produce an intermediate or API (drug substance) meeting its predetermined specifications and quality attributes. (TR14) (TR42) Establishing documented evidence which provides a high degree of assurance that a specific process will consistently produce a product meeting its predetermined specifications and quality attributes. (TR44) The collection and evaluation of data, from the process design stage through commercial production, which establishes scientific evidence that a process is capable of consistently delivering quality products. (TR54) (TR57) (TR74) The collection and evaluation of data, from the pro­cess design stage through commercial production, which establishes scientific evidence that a process is capable of consistently delivering quality product. The documented evidence that the process, op­erated within established parameters, can per­form effectively and reproducibly to produce a medicinal product meeting its predetermined specifications and quality attributes, as described in EMA, EU GMP, Part 1, Annex 15, drug/me­dicinal product. (TR56) EMA: The documented evidence that the process, op­erated within established parameters, can per­form effectively and reproducibly to produce a medicinal product meeting its predetermined specifications and quality attributes. US FDA: The collection and evaluation of data, from the process design stage through commercial pro­duction, which establishes scientific evidence that a process is capable of consistently deliver­ing quality products. (TR60-2) The documented evidence that the process, operated within established parameters, can perform effectively and reproducibly to produce an intermediate or drug substance meeting its predetermined specifications and quality attributes (1, 17). (TR60-3)

A written plan pre-approved by the quality unit that specifies critical steps, controls, and measurements. The process validation protocol states how validation will be conducted, identifying sampling, assays, specific acceptance criteria, production equipment, and operating ranges. Results obtained for each study described in the protocol should be evaluated in an associated process Validation report. (TR14) (TR42)

A report approved by the quality unit that summarizes specific tests performed, compares the test results with the protocol acceptance criteria, and addresses deviations encountered during the study. (TR14) (TR42)

Validation of an existing manufacturing process that occurs by reviewing data from relevant historical and test production records. (TR14) (TR42)

Repeating partial or full validation of a process after a process change is implemented. Re-validation is change-based, not time-based. (TR14) (TR3) (TR42)
