During the freezing phase, which occurs 60 hours after loading, the temperature of the freezers is monitored. If the temperature is warmer than the previously recorded temperature, supervision was notified. Additionally, after the freezer temperature drops below -60°C, the temperature recorded may be warmer due to the freezer operation caused by the freezer cycling to maintain the freezer set point, which is acceptable. A review of the log for the reported batch confirmed that all freezer temperatures were acceptable. Samples are then stored until the product is released for distribution. There were no issues recorded during the packaging or storage process which may have impacted the potency of the drug product.
