GLPs: DefinitionGLPs: Definition

Basis: 21 CFR Part 58: GOOD LABORATORY PRACTICE FOR NONCLINICAL LABORATORY STUDIES

GLPs: Good Laboratory Practices Nonclinical laboratory study means in vivo or in vitro experiments in which

test articles are studied prospectively in test systems under laboratory conditions to determine their safety. The term does not include studies utilizing human subjects or clinical studies or field trials in animals. The term does not include basic exploratory studies carried out to determine whether a test article has any potential utility or to determine physical or chemical characteristics of a test article.

GLP does not mean: Requirements for recording QC data Requirements for any laboratory work (e.g., R&D or

QC) Definition of a material grade (“GLP-grade”)

GLP does not pertain to ANYTHING other than a nonclinical laboratory study.

GLPs have more specific requirements, compared with other regulations.

GLPs apply only to nonclinical safety studies. GLP studies can be in vitro or in vivo. Nonclinical studies are critical to any clinical

study leading through market application (drug, devices, biologics).

PitfallsPitfalls

Not ensuring the test article is representative of the process, materials, etc., of the clinical product You may have to repeat the study Your clinical study could be delayed

Not using the data obtained from the study to establish monitoring in the human study.

Not reporting safety issues from a GLP study while the clinical study is occurring.

Assuming the contract lab knows what they’re doing (trust but verify)

Not seeking FDA concurrence of the study design before starting (risky)

Not carefully reviewing the draft report before sending it to FDA.

Not reporting ALL data obtained from a nonclinical study - you can discount it but you must report it.
