Alvotech Complete Response Due to Inspection
FDA has issued Alvotech a complete response letter (CRL) for its BLA for AVT02, a high-concentration biosimilar candidate referencing AbbVie’s Humira (adalimumab). The letter cites manufacturing deficiencies that were documented during a 3/17 reinspection of the company’s Reykjavik, Iceland facility, according to the company. “The CRL noted that certain deficiencies … must be satisfactorily resolved before the application can be approved,” it says.
The Form FDA-483 from the inspection cited eight observations. They were:
- failing to have in writing and fully follow the responsibilities and procedures applicable to the quality unit;
- failing to have the written records of out-of-specification and deviation investigations include the conclusions, follow-up, and adequate root cause analysis;
- the quality of incoming stoppers was inadequate;
- failing to exercise appropriate controls over computers or related systems to assure that changes in quality control records are instituted only by authorized personnel;
- container closure integrity assay validation was inadequate;
- failing to establish and follow procedures designed to prevent microbiological contamination of drug products purporting to be sterile;
- aseptic processing areas are deficient regarding the system for cleaning and disinfecting the room and equipment to produce aseptic conditions; and
- equipment used in testing and holding operations in support of drug substances and drug products was not of appropriate design, of adequate size, and suitably located to facilitate operations for its intended use.
