Revance Therapeutics FDA-483 Released
FDA has released the FDA-483 with five inspection observations issued following a 6/21-7/2 inspection at Revance Therapeutics, a Newark, CA, drug substance and drug product manufacturer. The inspection observations were:
- current release and stability cell bank testing methods are insufficient to monitor quality and shelf-life of working cell bank;
- the current manufacturing process is not the process proposed for licensure;
- the firm’s quality unit lacks the responsibility and authority for the control, review, and approval of outsourced activities, which includes defining the responsibilities and communication processes for quality-related activities in a written agreement;
- actual yield and percentages of theoretical yield, indicators of process performance, are not determined after each appropriate phase of manufacturing for a redacted drug product; and
- the responsibilities and procedures applicable to the quality control unit are not always in writing.
