Guest Commentaries

This page features some knowledgeable people writing on current topics of interest. I am pretty proud of the impressive list of Guest Contributors that have graced the pages of GxP Perspectives. One of the philosophies of this blog is that a lot of the common problems facing public health and drug & device development could be solved by those of us who do the work. That’s why I want to hear from GxP professionals on areas of their expertise. If you have a topic you wish to write about, please let me know!

    Hello Carl:

    I just finished up an extensive review of the FDA’s 2011 investigator warning letters (total of 6)and I found the Warning Letter issued to Martin Zaiac, MD on 3/21/2011 to be an interesting case analysis.

    This PI managed to commit 5 major violations, including the inability to identify a full-term pregnancy, peripartum cardiomyopathy, pneumonia, morbid obesity and substance abuse resulting in the patient’s death. This investigator was terminated from the study, and he failed to report his site closure to the IRB until after the FDA inspection.

    I would love to hear your expert opinion on this case as it is apparent this investigator did not take heed to his signature on the Form 1572.

    I noted this investigator states on his website that he is one of the top dermatologists in Miami Beach, FL.

    My question is, what impact does a for-cause site close-out and ultimately a for-cause FDA inspection have on an MD’s private practice?

    Looking forward to your commentary on this case.

    Thank you.
