Investigational Product Accountability

Clinical trials are conducted for new investigational products and also to explore additional endpoints/indications for marketed products or combinations.  The medication dispensed in the clinical trial is governed by country/local requirements and strict regulations dictating that it must be tracked and accounted for throughout conduct of the trial.  There are also regulations regarding how the medication is packaged in order to protect the safety and welfare of the subjects and also to maintain the integrity of the trial.  The guidances and guidelines (ICH GCP Guidelines 4.6) spell out recommendations for labeling, packaging, transport and storage.  Suffice it to say, the investigator is on the hook (although he may delegate some of this responsibility to a pharmacist or another person qualified by skills and experience) for confirming receipt of the investigational product (IP), storing/dispensing it properly, and ensuring subjects are compliant with the specified regimen.

The gold standard in clinical trial design is the blinded placebo controlled trial; in these studies the subject and/or the investigator doesn’t know which treatment is being given and that helps maintain objectivity and reduce bias when assessing safety and efficacy. Reference the FDA website for information on various types of trial designs. In order to maintain the blind in the study, the sponsor will deploy a system to disguise the active treatment and the comparator (achieved through manufacturing, opaque packaging, etc.) but also allow identification of the product(s) in the event of an emergency.  Many trials use an electronic randomization system with controlled access so that drug can be assigned according to a pre-determined stratification (to balance inventory across multiple study sites) and also to provide a record of any blind breaks.  Alternatively, trials may use sealed paper randomization envelopes and/or unblinded monitors.

The investigator needs to maintain records of shipment receipt and records of accountability for the disposition of the investigational product throughout the trial. Investigation product may be provided to the investigator in the form of blister packs, sealed bottles, syringes, inhalers, or some other delivery system.  The investigational product will have storage specifications in accordance to the instructions from the sponsor and applicable regulatory requirements.  If the investigational product is temperature controlled, it may be shipped to the study site with digital data loggers that monitor and record the temperature during shipping. The investigator will also need to demonstrate that the temperature has been recorded and maintained according to specifications since the time of receipt (using a paper log, digital device, or some other documentation).

Once the investigational product is at the site, as monitors we can review expiration dates and inspect the product regularly and document the inspection in our reports.  We need to check that everything that was supposed to be used is not present (counting the used IP and reconciling our counts against the tracking documentation), and also that everything that is supposed to be intact has not been used.  We can also physically check that blinding envelopes plus unused investigational product foils and seals are intact and have not been tampered with.  We will review the temperature logs to record and report any temperature excursions.  We will also verify that there is restricted access to the investigational product; controlled with double lock and key.  Finally, we can review the schedule of planned activities at the site and ensure there is adequate supply of investigational product to support continued research efforts.  We will record any deviations or discrepancies and report to the study team and retrain the study personnel as appropriate.

This red tamper-evident tape reveals the word "opened" if you lift and replace it.

Repeating the accountability exercise at every visit can be a time consuming process. If it isn’t stated in your study monitoring plan, ask your Project Lead if interim return/destruction of the used/expired investigational product is permitted.  This is certainly advantageous to waiting until the end of a long study and then trying to reconcile all the paperwork and re-count everything.  As an alternative, you may choose to box up the used investigational product and seal the box with tamper evident tape (at all seams) or just put the tamper-evident tape completely around the investigational product packaging itself and leave it in the controlled secure IP storage area to verify again at the next visit (though this will likely take more tape and it is actually kind of expensive. Also consider initialing across the tape or signing your name so any tampering will be additionally evident).  With your study team’s permission, this may be sufficient to avoid recounting all the investigational product at every single future visit, hopefully they will provide permission for you just to review that the taped up IP is still present and unaltered.

Occasionally drug will be transferred between investigational sites.  This creates a flurry of documentation and if you are asked to participate in a drug transfer you will receive plenty of training from your study team so I will just move on now.


At the conclusion or termination of the trial or in the event of a recall, the investigational product (and the blinding envelopes or supplies if applicable) will be returned or destroyed as specified by the sponsor although sometimes it may be donated to a hospital, pharmacy, or doctor. Per ICH E6 8.4.2 there are requirements for documentation of investigational product(s) destruction.  Any drug or packing that was not returned by the study subject will be documented on the accountability log and it is recommended that there also be documentation in the source documents of counseling the subject on the requirement to adhere to all protocol procedures and instructions.  Documentation regarding the receipt, disposition during conduct, and return/destruction are to be kept on file in the Site Master File and the Trial Master File (your study team, SOPs, or monitoring plan will inform you which file gets the original documents and which gets the copies).  OK, a lot of material here, please let me know if there is anything you want me to clarify or expand further on.

Close-Out Visits

I've done about 10 close-out visits in the last few months so it feels like a good time to write a short article explaining what the objectives of these visits are and how a typical close-out visit (COV) is conducted.

A COV will occur once subjects are no longer being dosed, all the data have been collected (there are no more outstanding AEs/SAEs & all outstanding Queries/data clarification forms have been resolved appropriately), the database is locked and ready for statistical analysis, and the study conduct has ended. At this point, the site's contributions are over so the monitor returns for one final visit to shut down the site. The whole concept behind a close-out visit is to ensure that everything is neat and tidy at the study site and that the documentation is well organized and will remain intact and be accessible in the future as needed for regulatory reasons. A sponsor or the FDA should be able to return to the place of study conduct years later and re-create exactly what occurred at all points during the trial by reviewing the regulatory documentation, subject and source documentation, full medical charts, and any other applicable study records. Documentation is everything in our industry and we are always saying, "if it isn't documented it didn't happen." If thorough and accurate records are not maintained, the PI cannot prove that the study was conducted in accordance with the protocol and all applicable regulations and that subject safety was adequately monitored throughout the conduct of the trial.

Site Supplies and Drug Return

We are using tamper evident tape to
box up investigational product for return.
If the tape is lifted it leaves behind an
artifact to show it has been tampered with.

One of your major objectives at the COV will be to assist the site in dealing with any unneeded study materials or supplies. With permission from the sponsor, some of these activities can even take place before the close-out visit as you remotely supervise. The close-out duties will likely include disposing of or retrieving all unused lab or study supplies such as patient handouts, electronic diaries, etc. In most cases, you will have the site generate a file note or similar documentation so there is a record indicating that study supplies were disposed of or moved off-site. 9 times out of 10, the Investigational Product (unused and the used packaging) will need to be inventoried, accounted for in drug logs, and then shipped to a depot or destruction facility. Sometimes the drug will be destroyed on site by a pharmacist or according to the site's SOP but this is really the decision of the sponsor. If you are lucky, you were able to pack up and ship back drug routinely throughout conduct otherwise you will have to deal with it all at the end.


Essential Documents
You will have the PI sign off on any tracking logs that were used during the study. The original will be placed in the site's Regulatory binder but you will retrieve a copy for the Trial Master File. You will ensure that a Subject Identity List was completed and will be kept that lists the contact information for all treated subjects (you will not take a copy of this document as it has private information and stays at the site only). Documents you will take copies of include: Site Visit Log, Subject Screening AND Enrollment Log, Delegation of Authority Log, Proof of Drug Receipt, Subject Specific Investigational Product (IP) Accountability Logs, Copies of temperature/freezer logs, Site Initiation Statement, Training Documentation, Overall Site IP Log, Protocol/Amendment Signature Pages, Any updated 1572s, medical licenses, or CVs, Site communications to the IRB/IEC (ethic committee), and the IRB Final Status Document. Obviously in a study with many safety reports, a long line of routine monitoring visits, multiple site hand-offs/transitions between several different monitors, or a slew of important correspondence, checking that the essential documents binder(s) is in perfect order can be a time-consuming task.

Subject Records
Although you will have already verified this throughout conduct, the close-out visit is your last opportunity to be absolutely sure that the appropriate version of signed and dated Informed Consent Forms are on file for every subject. You will also check that all source is complete (all lab reports and ECGs have been signed and dated with Clinical Significance assessed by the PI/Sub-I) and that all AEs/SAEs have been signed off by the PI/Sub-I and that they were followed to resolution as specified by the protocol. Finally, check that all significant Protocol Deviations (study procedures not conducted according to protocol, enrollment of inappropriate subjects, dosing errors, consenting errors, unblinding, subjects developing withdrawal criteria yet continuing in study, etc.) have been properly recorded and the sponsor/IRB has been notified as appropriate.

PI Responsibilities
Discuss with the PI his/her responsibilities including: query/data collection following the close-out visit, essential document retention, publication rights, and the necessity to update the Financial Disclosure statement if there are changes in their financial interest for up to one year following completion of the study. Finally, explain to the PI the potential for regulatory agency inspection and the requirement that the site notify the CRO/sponsor immediately if contacted for an audit/inspection.

Assuming you have done a thorough job in monitoring throughout conduct, the COV should be a relatively short-visit. Meeting with the PI to discuss their regulatory responsibilities post trial conduct and obtaining required signatures usually takes less than 20 minutes assuming they are an experienced investigator and are already familiar with the GCP schpeel. Drug return often takes several hours but you can prepare most drug return documents in advance of the visit by using sponsor or IVRS reports and usually save a considerable amount of time on-site. You should have been reviewing the regulatory binder at every visit throughout conduct so it should really be in order at this point and stuffed to the brim - I usually budget no more than an hour to ensuring that the binder is complete.

After you complete the close-out visit, you will write a report to the sponsor to let them know that all of the objectives were completed and a follow-up letter to the site thanking them for their participation and informing them that there are no further pending action items. Any new regulatory documentation you copied while on site will need to be forwarded to the Trial Master File so that the sponsor's documentation is a true mirror of what is on site.

Routine Monitoring Visits

Routine or Interim Monitoring visits are basically any visit that occurs after the site is initiated and up until the site is closed out. As monitors, we visit our sites periodically to ensure that they are compliant with all the regulations, subject safety is being adequately followed, data is being captured in a timely and reliable manner, the Investigational Product is being handled as per protocol and relevant regulations/guidelines, there are no significant deviations from the planned study protocol, all important study documentation is being generated and stored properly, and that the research site is adequately supplied in regards to lab kits and other pertinent study materials. The ultimate purpose of our job is to protect subject safety by monitoring the trial conduct for ICH/GCP compliance.

When planning your monitoring visits
it is helpful to have a reasonable expectation
of how think the medical records and source
documents will be. Know in advance how much
you will need to review so you budget enough
time to successfully complete your objectives.

Your agenda from visit to visit may vary slightly based on the length of the study and how many times you plan to visit, the amount of time you spend to plan at the site for this particular visit, the site's progress to date (if a site has yet to enroll any subjects you surely won't have any CRFs to review or pull), and where you are at with the general monitoring plan (for example, drug accountability may be done all along or just at close-out).

Prior to your visit you will contact the site to set up a suitable time for your visit. Visits typically last a day or two. Ideally, the PI would be available to meet with you during the visit. You will send a confirmation letter to the site once a date is set (be sure to confirm the address before you go if you haven't been there before!). More often than not, your study lead will provide you with a monitoring visit checklist or at the very least, a monitoring report template so you will know exactly what tasks you are expected to perform on-site and what topics to cover. Here are some of the specific tasks that are routinely performed at these visits:

1. Informed Consent Form (ICF) review: You are ensuring that every subject was adequately informed and consented to the study before any study procedures were completed (I recommend checking lab draw times and ECG times - if required at the screening visit - against the consent time to be extra sure that the consent was the first study procedure to occur). There are other state specific regulations you will need to know and monitor for. For example, in some states subjects must be 19 to participate and in California every subject must sign the 'CA Bill of Rights' document, etc. Sometimes there are multiple versions of a consent due to a change in the facility address or the details of the protocol. Ensure that all subjects signed on an IRB approved version (each page will be stamped in the upper right hand corner and the version date will be printed on each page). Proper consenting of subjects is critical to ensure the security and privacy of health data and that subjects are adequately informed of the study procedures, risks and, benefits. If the consent is not signed or properly completed inform the Study Coordinator and do not review this subject's medical chart until consent has been properly obtained.
2. Check for Serious Adverse Events (SAEs): Per the guidelines, an SAE is any untoward event that results in death, prolonged or new hospitalization (longer than 24hrs), significant disability, or congenital anomaly (birth defect). If the event has not been reported, assist the Study Coordinator in doing so and inform the sponsor immediately.
3. Review Protocol Compliance: In your chart and source document review, you can verify that subjects were sign at the right times and the right procedures were conducted as per the protocol. You will have study-specific procedures for reporting deviations. Deviations of a serious nature may be reported in an expedited manner and may need to go to the IRB (dosing errors, unblinding of study treatment, subject enrolled that did not satisfy entry criteria, etc.)
4. Compare source documents to Case Report Forms: You are checking that the data in the chart matches the Case Report Forms (which will be later entered into the clinical database and combined with other subject's data to complete the safety and efficacy analysis for the Investigational Product). Determine whether or not CRFS being completed in a timely manner. You also want to verify that the source is complete, neat (all corrections must be compliant with the regulations - white-out is not OK), attributable (who wrote it? Is it initialed and dated), contemporaneous (was it written at the time the procedure was completed?), valid (is the data collected even possible?), etc. Sometimes you will be asked to pull the case report forms and send them in to data management and other times they will stay at the site until the end of the study.
5. Review Investigational Product (IP): The study protocol will explain how the IP is to be stored, dispensed, and returned. Verify that all of this occurred properly by reviewing temperature logs, storage facilities, administration records, IVRS entries/reports for subject-specific IP accountability, and speaking to the relevant personnel.
6. Regulatory Binder / Essential Documents Review: Determine if any forms need to be updated or pulled for the Trial Master File (TMF). The TMF is meant to be an exact replica of all the documentation at the site. Specific information regarding the contents of the essential documents binder are covered in section 8 of the guidelines.
7. Confirm Site Adequacy / Site Status: Determine if there are new staff at the site or if staff have left. Can the site manage with current staff? Has the site or the lab moved? Confirm that there are adequate study supplies
8. Study-Specific Monitoring Tasks: Depending on the protocol, you may need to perform additional tasks such as shipping materials back to headquarters (for example lab specimens, xrays, etc.), calibrating or reviewing calibrations of equipment, site training, checking eDiary compliance, etc.
9. Review Ongoing or Pending Issues from Previous Visits: At some point during every visit work with the staff to resolve any items identified at previous visits as ongoing issues. Indicate in your report once these are resolved.
10. Review of findings with the site: Whether or not you find issues during your visit, keep the site staff posted on your progress and how things are going. Especially, if the Principal Investigator is not available during the visit, be sure to summarize everything accurately and completely in your follow-up letter.

Try to schedule your next (or next several) visits before you leave the site. After the visit, write your report and send the follow-up letter within a week or per your monitoring plan and refer to your company's SOPs. Always report significant compliance issues to your management, the sponsor, IRB, and QA as appropriate. Remember that you must document everything because of the adage, "if it isn't documented, it didn't happen". Please contact me if I can elaborate on anything or if you think I've left something important out.

Home from the Investigator's Meeting

I've been assigned another study and attended a kickoff and Investigator Meeting on the East Coast last week. As I mentioned in my last post, an Investigator's Meeting is basically a chance to get all the doctors and staff together at one venue with the sponsor (usually a fancy hotel or somewhere fun) so that all the details of the study protocol can be reviewed and everyone's questions get answered. Also, because a lot of money is spent at these meetings to woo, wine, and dine the Principal Investigators (PIs), the meeting has the bonus effect of getting everyone psyched up and excited/competitive about enrolling in the study.

For my new study (it is a high cholesterol drug therapy study) I will have 11 sites each of which needs to be visited at least every 4 weeks depending on enrollment. There are 60 PIs total and 4 other CRAs but I am the only one on the West Coast. I am lucky that 7 of my sites are located near one another in LA so I can combine my visits into longer trips and not have to fly so often. I also have 2 sites in Phoenix, a site in Seattle, and a site 1.5 hrs drive East of my house. In any case, this is a heavy site load but luckily it is a straightforward study and the PIs seem to be both experienced and motivated.

An electronic patient diary looks just
like a little PDA and the patient gets
an alarm to remind them it is time
to take their medicine or fill out a
little outcomes summary. This data
gets sent in via the telephone or
loaded into a computer and is used
in the study analysis.

The trial leverages some cool technology such as an electronic data capture system (so CRFs go into the computer in an EDC system rather than on triplicate forms) and the patients all get electronic diaries (little palm pilot devices) so they can capture adverse events and be reminded when it is time to take their medicine, plus the medicine (Investigational Product - IP) comes in blister packs one week at a time, so drug accountability should be a cinch thanks to this clever packaging. This is a proof of concept study so there are 6 different study arms (some patients get placebo, some get the real drug, some get a mix of both...) and only 275 subjects will be enrolled. The subjects take their meds for around 7 weeks. Recruitment is anticipated to end in mid-April so it is a really short enrollment period. The Inclusion exclusion criteria are very tight so a high number of screen failures are expected (up to 800). Luckily, screen failures will not get their own casebooks but just be captured in the Integrated Voice Response System (IVRS) web portal.

In my next post I will tell you more about how to prepare for a CRA interview and what types of questions you can expect to be asked. Then I will post about Routine Monitoring Visits, as promised. Let me know if there are other topics that are of interest to you by emailing me or leaving me a comment here and I will be sure to address them in future posts.

Introduction to Monitoring

I've been out on the road for the past few weeks assisting some other monitors to review patient's medical records and the data that has been collected for the clinical trial. It occurs to me, that it would be beneficial at this point to further describe to you the roles and expectations of a Clinical Research Associate (CRA).

In a pharmaceutical/biotech company, teams of scientists are working to discover new molecules, compounds, and foundations for new drugs. In addition, these same scientists sometimes work to re-formulate current drugs or apply them for new diseases and indications (all of this work is done in animal models before the human clinical trials can begin). It is at this point that monitors such as myself come into play. Once an experiment that involves humans is designed, monitors help the company choose qualified and interested physicians to carry out the study. These 'investigators' are reimbursed for their efforts to conduct the trial and a CRA may also help negotiate the budget and/or contract between the parties involved.

A CRA job is a traveling job. Sometimes we go to glamorous places but more often than not we are monitoring in hard to reach or otherwise obscure locations. 

Objectives when we visit the investigative site (Doctor office, hospital, research center, etc.) include: 1) perform pre-study tasks during a Pre-Study Visit (PSV), 2) kick-off the study with a Site Initiation Visit (SIV), 3) routinely check back with the site regarding subject enrollment, trial conduct, and data collection during one (or typically many!) Interim Site Monitoring Visits (MV), and finally 4) shut down the site after their participation has ended during a Close Out Visit (COV). Before and after each visit, there are a variety of tasks and communications that need to occur in regards to preparing for, scheduling, confirming, and then following up on items from previous visits. Read some of my other blog posts to learn more about Site Initiation Visits, Routine Monitoring Visits, and Close-Out Visits.

Also, between visits, a CRA needs to regularly contact the sites and perform site management activities such as answering questions regarding the study design, encouraging enrollment, sharing tips from other sites, and distributing study drug (Investigational Product, IP), and managing site supplies inventory levels (often you are assigned up to 10 different sites to manage but this really can vary depending on geography, how many patients/doctor sites are participating, how many monitors are on the study, how complex the trial is, and a variety of other factors).

I'll explain more regarding the key tasks at each visit in later articles. There are many Federal and International regulations that apply to human research to ensure that the studies are valid, reliable, and above all, that the rights of the participating subjects are protected and we'll also get into those soon.
