Question
I would like to ask a question regarding the temperature control of investigational drugs.
We store investigational drugs from several companies in one refrigerator, and the temperature is controlled by a thermometer provided by the sponsor as well as our own thermometer, and we measure the temperature daily.
Recently, a temperature deviation was found in the thermometer provided by Company B for the storage of investigational drugs. However, when we looked at the readings of the thermometer provided by Company A and the thermometer at our hospital, both thermometers were within the normal range, so we assume that there was no actual measurement problem. (According to the investigation by the thermometer manufacturer), there was nothing wrong with the function of the thermometer provided by Company B.
In order to avoid such a situation in the future, the Investigator Site should also ensure the accuracy control of the thermometers and unify the measurement with one thermometer, and the sponsor should also check the refrigerator temperature using the Investigator Site's thermometer instead of providing its own thermometer. What is your opinion on this point?
JPMA's Opinion
If the Investigator Site's thermometers are thoroughly managed for accuracy, installed in a location where the temperature inside the storage unit can be evaluated (taking into account temperature differences within the storage unit), and the temperature is appropriately recorded, then we do not see any problem with using the thermometers and records of each Investigator Site.
However, there may be cases where individual requests (frequency of measurement, output format of records, installation of individual thermometers) are made depending on the contents of the study protocol and characteristics of the investigational drug. In such cases, the reasons and necessity of such requests should be discussed with the sponsor.
