Dear Forum-
We have a situation that I haven't previously encountered. In a clinical trial, an SAE occurred due to hospitalization, but the patient has not released the medical records to the clinical site. The principal investigator believes it will be unrelated however he cannot give a causality until he reviews the hospital records. If the records won't be released and a causality cannot be determined due to lost to followup, how is this reported to the FDA?
Thank you for your guidance.
