Michael, in my lexicon, QC is done by those who produce the product (e.g., clinical data). That would be the clinical investigator, not the study sponsor.
QA is done to
assure management (eg., a study sponsor) that the product being produced meets quality requirements. It is up to management to decide what it needs to feel assured, including who will conduct QA on its behalf, and what type of QA activities will be conducted. If management feels the need to have someone check on data quality on an ongoing basis and to also have someone else verify data quality at various points in the study, then that's its prerogative. If it feels the need for only one or the other, or neither, then that is its perogative as well.
Another common view is that QC is product-focused, while QA is process-focused. This would dictate that all activities intended to evaluate the quality of data for a specific study (manufacturing lot) are QC, and that all activities intended to determine whether the process being used will reliably produce acceptable quality across studies (manufacturing lots) are QA. From this perspective, both monitoring and auditing of the data for a specific study are QC. I think this viewpoint is adopted more for pragmatic purposes, rather than as a quality philosophy, because it is often the only way to persuade management, which likes to think it has both QC and QA, to support activities that evaluate processes in addition to product.
Certainly various regulations and standards will specify the who and the what and the how often. For studies to be conducted in compliance with specified regulations and/or in conformance to specified standards, management's authority to decide these things is curtailed. Regardless, monitoring and auditing both remain forms of QA, IMO.
The term "monitoring" was coined within the pharma space way back, I don't know by whom, but not by quality professionals. Pharma, which at the time managed and monitored its own clinical trials, had no clinical research quality anything in place at the time, and CROs were virtually non-existent.

Actually, monitoring and auditing are two completely different things and roles in GCP. Monitoring is the ongoing QC oversight of a clinical study to check on data integrity, study execution and ethical oversight, Auditing on the other hand, is a QA function performed at various points to verify study execution and data integrity. It is really no different than the role of QC and QA in GMP (or GLP).
Monitors typically work for the company that is sponsor of the study, thought these days this is often subcontracted to a CRO (who works for the sponsor). QA is performed by a separate QA function (or subcontractor) who reports independently to management. Monitoring of a study does involve actual site visits in order to verify collected information against the subject medical records. This is a cornerstone of clinical monitoring.
Safety monitoring is a different function that is handled by professionals in the safety oversight dept (pharmacovigilance). These persons do need specific expertise in the review and interpretation of safety information.
It is expected that all personnel involved in the management and oversight of a clinical study must be adequately trained in clinical research and GCP. Therapeutic experience can also be very helpful.

I don't think a clinical monitor is different from an auditor. I think you just need to figure out on whose behalf they are auditing the quality and completeness of the data, and who is responsible for collecting those data. Usually the study is monitored on behalf of the sponsor (because it's the sponsor that needs quality and complete data) and the clinical investigator is responsible for collecting the data. As the sponsor, I would want the monitor to be independent of the clinical investigator, because I would see that as a conflict of interest. Who pulled together the clinical documents is irrelevant, unless the monitor is also auditing the quality of those documents. On the contrary, the more the monitor knows about the study, including the documents, the better the job they can do at monitoring it.
I think the qualification that are needed to monitor data quality is an understanding of clinical data (can you read a patient chart, figure out if an adverse event was severe) and in the general concept of "evidence," since the monitor needs to confirm that there is evidence (eg, lab report) to support the data that the clinical investigator is reporting. I would want my study monitored for data quality, regulatory compliance, and subject safety. A lot of sponsors also want study progress to be closely monitored.
I think subject safety should be monitored by a clinical professional. This does not mean that they have to make site visits, but that they should review the data to assure that no safety issues have emerged during the course of the study.

A clinical monitor can be an employee of the company and even part of the clinical team. There is no requirement/expectation that they be independent of the clinical team. This is different than an auditor, who should be independent of the clinical group. The qualifications for a monitor are generally described in numerous guidances (such as ISO 145155 and ICH) but this person can be anyone who is qualified. It does not matter if the work in regulatory as long as they are properly trained and qualified to be a monitor.

Hi everyone,
What is the training and experience study data monitors? Note, the study monitor is somebody who oversees the quality and completeness of the data, not to be confused with the data safety monitoring committee. I have searched ISO 14155 and also did some research online. It looks like somebody with CRA credentials can do it. But I also wonder if somebody representing the sponsor can do it too, e.g. an experienced regulatory affairs specialist with some training in clinical research. Does it matter that the person representing the sponsor was also heavily involved in putting together the clinical documents? The sponsor is a small company where almost everyone is involved in putting together the clinical documents.
Thanks.
