Reporting adverse event of a
drug is one of the most important aspects of conducting a clinical research.
Clinical trials are conducted to know the safety, tolerability and efficacy of
a new drug in human system, which in turn would decide whether that particular
drug would receive marketing authorization in a particular region and if the
drug receives marketing authorization what could be the potential side effects
and risks associated with the usage of that medicine. Different adverse events
caused by a drug/medicinal product have to be properly collected in time and
should be reported to the corresponding regulatory authority. As many
stakeholders are involved in a clinical trial process, reporting adverse events
thus become a joint responsibility of all the involved parties.Depending on the
seriousness, every adverse event has to be reported within particular time
period. Any delay in the reporting of the adverse event would be considered as
punishable for the sponsor company who is conducting the trial. Thus adverse
event reporting would be a joint responsibility for the sponsor (the Biopharma
company, Govt. agency or a particular physician who is conducting the trial),
investigator (the doctor who is conducting the clinical trial at site) and the
monitor (who would work as sponsor’s representative and monitor the trial
conducted at sites).
Sponsor responsibility
The sponsor should expedite
to all concerned investigator(s) working at different institutions(s), to the
IRB/IEC where required, and to the regulatory authority (ies) of all adverse
drug reactions (ADRs) recorded during clinical trials that are both serious and
unexpected. Such expedited reports should comply with the applicable regulatory
requirement(s) and with the ICH Guideline for Clinical Safety Data Management.
The sponsor should submit to the regulatory authority(ies) all safety updates
and periodic reports, as required by applicable regulatory requirement(s). The
sponsor should monitor if the clinical trials has been conducted in compliance
to the protocol, GCP guidelines and applicable regulatory requirements by
proper monitoring processes at regular intervals.
Monitor responsibility
Monitors are one of the
important stakeholders recruited by the Sponsor/CRO. The primary responsibility
of a monitor is to check whether the rights and well-being of human subjects
are protected during the conduct of the clinical trial. He/she would also check
if the reported trial data are accurate, complete, and could be verified from
source documents. Monitor has to check if the site team is conducting the trial
in compliance with the approved protocol, GCP, and the applicable regulatory
requirement(s).
The monitor should check if
the study has been conducted in site properly, by directly visiting the trial sites,
through continuous review of the records. Apart from direct visits the monitor
should communicate with the site through telephone, fax or email in the interim
period. Specific reports and data collected at site which may be indicative of
an unreported adverse event should be promptly instructed to the investigator
to report. This includes addition of concomitant medications at any visit, assessment
of symptoms reported by the subject, subject diaries and all medical record entries
collected after the initial study visit date and prior to the study end date.
Another major responsibility
of monitor would be to evaluate all reported adverse events to assess the need
for obtaining a follow-up report from the investigator. Cases where follow up report
might be required include, (i) a serious adverse event for which complete information
was not available from the initial report, (ii) previously reported adverse
event, for which any new information becomes available, (iii) finding a resolution
of a previously reported unresolved adverse event, (iv) early termination of a
subject for whom an unresolved event was reported, (v) study completion by a
subject for whom an unresolved event was report.
The monitor is the first
line of communication between the sponsor and investigator throughout the
study.One of the most critical functions of the monitor is
to assure that investigators are fully aware of working in compliance to responsibilities of immediate reporting the adverse events to the
sponsor and the IRB ( Institution Review Board) .To achieve this, the monitor
must teach the adverse event reporting requirements to investigators properly
and whenever required help them in future. Thus, the monitor must be
knowledgeable about the regulatory and sponsor-specific requirements for
reporting serious and non serious adverse events in clinical trials.
Investigator responsibility
The investigator would be
conducting the clinical trial at site. The investigator would lead the team working
at site, would conduct the research and provide treatment to the subjects and
collect their data. All serious adverse events (SAEs) collected by the
investigator should be reported immediately to the sponsor except for those
SAEs which according to the protocol or other document (e.g., Investigator's
Brochure) identified as not requiring immediate reporting. The investigator has
to send the immediate report of any serious adverse event to the sponsor by phone,
email, fax within 24 hrs. A detailed written report of the event should follow
within the next 48 hrs for most of the cases. The immediate and follow-up
reports should identify subjects by unique subjects identification number
assigned to the trial subjects.The investigator also has to report unexpected
serious adverse drug reactions to the regulatory authority (ies) and to the
IRB/IEC in compliance to the applicable requirement(s). Adverse events along
with abnormal laboratory findings (specially mentioned in the protocol as
critical for safety evaluations) should be reported to the sponsor according to
the reporting requirements and within time periods specified in the protocol. For
reporting of fatal outcome (death), the investigator should submit an additional
requested information (e.g., autopsy reports and terminal medical reports) to the
sponsor and the IRB/IEC with any additional requested information (e.g.,
autopsy reports and terminal medical reports).
Thus proper reporting,
monitoring of the AE reporting and successful coordination between the
different stakeholders finally results in successful reporting of AE data which
in turn helps to collect all the side effect, adverse effect of the drug and help
in the development of drugs with more
efficacy and less side effects.
