AveXis Inspection Observations
FDA has released the FDA-483 issued following a 7/24-8/2 inspection at AveXis, San Diego, CA, the control testing laboratory at the center of data manipulation concerns (see story) with recently approved Zlogensma, a gene therapy product intended to treat children less than two years old with spinal muscular atrophy. An agency statement says FDA was informed 6/28 about the data manipulation issue that affects the accuracy of certain data from product testing performed in animals submitted in the BLA reviewed by FDA.
The document contains five inspection observations:
- failing to thoroughly review any unexplained discrepancy, whether or not the batch has been already distributed;
- laboratory records do not include complete data derived from all tests, examinations, and assay necessary to assure compliance with established specifications and standards;
- failing to fully follow the responsibilities and procedures applicable to the quality control unit;
- laboratory records do not include complete records of any testing and standardization of laboratory reference standards; and
- failing to follow established test procedures.
