Free CCRC Detailed Role Questions and Answers — Questions and Answers
Question 1: Which of the following scenarios are considered SAEs?
- infection following surgery prolonging hospital stay (Correct answer)
- pregnancy resulting in normal delivery of twins
- boating accident with overnight hospitalization (Correct answer)
- use of illicit drug during the trial
Correct answer: infection following surgery prolonging hospital stay
A Serious Adverse Event (SAE) is defined as any untoward medical occurrence that results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, or is a congenital anomaly/birth defect. An infection following surgery that prolongs a subject's hospital stay directly meets the criterion of 'prolongation of existing hospitalization,' thus qualifying as an SAE.
Question 2: Which of the following are responsibilities of an IDMC/DSMB
- assess the financial aspects of a trial
- assess the progress of a trial (Correct answer)
- recommend initiating a trial
- recommend stopping a trial (Correct answer)
Correct answer: assess the progress of a trial
An Independent Data Monitoring Committee (IDMC) or Data Safety Monitoring Board (DSMB) is an independent group of experts that periodically reviews accumulating data from an ongoing clinical trial. Their primary responsibilities include assessing the safety and efficacy data, monitoring the overall progress of the trial, and making recommendations to the sponsor regarding the continuation, modification, or termination of the study. They ensure the ethical conduct and scientific integrity of the trial.
Question 3: The trough blood level for a once-daily drug should be drawn how long after the dose?
- 24 hours (Correct answer)
- 20 hours
- 48 hours
- 15 hours
Correct answer: 24 hours
The trough blood level of a drug represents its lowest concentration in the bloodstream, typically occurring just before the next dose is administered. For a once-daily drug, this means the trough level should be drawn approximately 24 hours after the previous dose. This measurement is crucial for determining if the drug concentration remains within the therapeutic window and for assessing patient compliance.
Question 4: A CRA calls a CRC to schedule the final monitoring visit. The sponsor requires that the PI be present. The only dates available for the CRA conflict with the PI's schedule. To prepare for the visit, the CRC should:
- reschedule the visit (Correct answer)
- have the PI sign all documents prior to the visit
- discard unused trial documents.
- notify the IRB/IRC
Correct answer: reschedule the visit
If the sponsor requires the Principal Investigator (PI) to be present for a final monitoring visit and the available dates conflict with the PI's schedule, the CRC's primary responsibility is to ensure compliance with the sponsor's requirements. The most appropriate action is to reschedule the visit to a time when the PI can be present. This ensures all necessary parties are available for the comprehensive review and discussion required at a close-out visit.
Question 5: A CRA is conducting a close-out visit at a site to review the regulatory documents. The CRC has prepared the following documents to be filed and/or sent to the sponsor: treatment decoding documentation code list, documentation of IP destruction and final report to the IRB/IEC. Which of the following actions should the CRC perform?
- Send the treatment decoding documentation to the sponsor (Correct answer)
- Remove the subject identification code list from the material to be sent to the sponsor. (Correct answer)
- Send copies of the IP destruction forms to the sponsor. (Correct answer)
- Remove the drug accountability log from the material to be sent to the sponsor
Correct answer: Send the treatment decoding documentation to the sponsor
During a close-out visit, the CRC must ensure all required documents are properly filed and submitted according to sponsor and regulatory guidelines. The treatment decoding documentation (e.g., randomization code list) is crucial for the sponsor to unblind the study data and is typically sent to them. Subject identification code lists should be retained at the site to protect subject privacy, and drug accountability logs are usually retained by the site for audit purposes, with copies of destruction forms sent to the sponsor.
Question 6: A CRC is screening subjects for an oral IP. All subjects must be stabilized on currently approved medications. Which of the following questions should be asked by the CRC?
- When was the last time your medication dose changed? (Correct answer)
- Have you made any dietary changes in the last month?
- When was your last chest x-ray and ECG?
- Do you have any difficulty swallowing oral medications? (Correct answer)
Correct answer: When was the last time your medication dose changed?
When screening subjects for a clinical trial requiring stabilization on currently approved medications, it is critical to ascertain the stability of their current treatment regimen. Asking 'When was the last time your medication dose changed?' directly addresses whether their existing medications are stable and have not recently been adjusted. This ensures that any observed effects during the trial are more likely attributable to the investigational product and not to recent changes in concomitant medications.
Question 7: A PI has an enrollment goal of 24 subjects. Ten potential subjects are seen each week. Twenty percent of the potential subjects will not be interested in participating. Fifty percent of the subjects who are interested will fail to meet one or more inclusion/exclusion criteria. How long will it take the CRC to fulfill enrollment?
- 6 weeks (Correct answer)
- 5 weeks
- 7 weeks
- 8 weeks
Correct answer: 6 weeks
To calculate the time needed, first determine the number of eligible subjects per week. Out of 10 potential subjects, 20% are not interested (10 * 0.20 = 2), leaving 8 interested subjects. Of these 8, 50% fail screening (8 * 0.50 = 4), meaning 4 eligible subjects are enrolled per week. To reach an enrollment goal of 24 subjects, it will take 24 subjects / 4 subjects/week = 6 weeks.
