CCRP Exam Dumps : Certified Clinical Research Professional (CCRP)

TheInvestigator’s Brochure (IB)compilesclinical and nonclinical dataon an investigational product relevant to human study.

ICH E6(R2) 7.2.3:The IB should summarizenonclinical pharmacology, toxicology, pharmacokinetics, and efficacy data, including results of animal studies.

ICH E6(R2) 7.2.4:It should also includeavailable clinical trial dataand safety experience.

The “results of recent nude mouse study” (B) are nonclinical data, which appropriately belong in the IB. Lab draw requirements (A), dispensing instructions (C), and schedules of events (D) are operational/procedural and are found in theprotocol, not the IB.

Thus, the correct answer isB (Results of recent nude mouse study).

This question tests drug accountability and dosing calculation, which is central to ICH E6(R2) 4.6 (Investigational product management). Subjects must receive the correct supply and any discrepancy must be reconciled.

The prescribed regimen is 2 mg twice daily = 4 mg per day. With 1 mg tablets, this equals 4 tablets daily. Over 10 days, the subject should consume 40 tablets (4 × 10 = 40). Since 45 tablets were dispensed, the subject should have 5 tablets remaining after 10 days.

Accurate accountability ensures trial integrity and subject safety. Investigators are responsible for maintaining investigational product (IP) records, including dispensing, usage, and returns. According to ICH:

4.6.3: “The investigator/institution should maintain records of the product’s delivery to the trial site, the inventory, the use by each subject, and the return to the sponsor or alternative disposition.”

4.6.5: “The investigator should ensure that investigational products are used only in accordance with the approved protocol.”

Thus, the correct answer is C (5 tablets remain). This reflects proper dosing compliance and highlights the importance of meticulous IP tracking in clinical trials.

When reviewing protocols, IRBs/IECs are primarily responsible forsafeguarding human subjectsby evaluating risks, benefits, and fairness in subject selection.

21 CFR 56.111(a)(3):“In making its determination the IRB shall determine that… selection of subjects is equitable.”

45 CFR 46.111(a)(3):Repeats this requirement, emphasizing fairness across gender, race, age, and socioeconomic status.

Other options:

Patient population availability (A) is afeasibility issue, addressed by investigators and sponsors, not IRBs.

Education of the study team (C) is confirmed by thesponsor and investigator, not IRB.

Funding sources (D) may raise conflict of interest concerns, but they are not IRB approval criteria per federal regulations.

Thus, IRBs focus onjustice and fairness in subject selectionas part of the Belmont Report principles.
