Clinical data management has massive career development, and the people in this position experience tremendous career development. You should aspire for this position and experience the advantages of this massive career development. Here are clinical data management interview questions and answers you need to practice in order to pass your next interview.

1. What Is Meant by Masking or Blinding?

In masking or blinding, a researcher hides the details from the research subject, even if the research subject is receiving a placebo, investigational product, or current standard treatment. There are two types of binding: Single and double binding. Single binding is where the patient is unaware of the treatment while double binding, neither the patient nor the researcher knows the treatment. Masking or binding helps eliminate biases in the treatment process that the researcher is investigating.

2. What is Placebo?

Placebo refers to a powder, pill, or liquid that has no active ingredients. Placebo helps researchers to isolate the study treatment effect. They are a significant part of clinical studies. They give researchers a comparison point for new therapies to prove if they are effective and safe. Additionally, they provide the clinical data managers with the evidence they need to use to regulatory bodies to approve a new drug.

3. What is a Patient File? What Information Does It Contain?

A patient’s file contains the medical and treatment history of the patient and demographic data. It can also have paper records or a combination of both computer and paper records. The patient file is significant for the continuity of care for the patients. It’s also essential for defending a complaint or clinical negligence claim.

4. Define the Different Phases of Clinical Trials

There are four major clinical trial phases and include:

  • Phase I: Human pharmacology trials
  • Phase II: Therapeutic exploratory trials
  • Phase III: Therapeutic confirmatory trials
  • Phase IV: Post-marketing surveillance trials

Phase I trials take one or more years and test one or more combinations of objectives. It also includes MAD, SAD, and food effect studies. Phase II trials last for one or two years and test the effective dose and the dosing regimen. Phase III trials range from 3 to 5 years and are called randomized, controlled, and multicenter trials and are significant for the approval of drugs. Phase IV trials are those that the regulatory authorities require the manufacturer to take for competitiveness.

5. What are Orphan Trials?

Orphan trials are tests that the clinical manager performs on drugs designed to treat diseases that affect less than 200,000 people. They carry out the test on a small number of extremely sick people and see if the drugs work immediately.

6. What is Bioequivalence?

Bioequivalence is where the clinical manager evaluates the anticipated in-vivo biological equivalence of two proprietary preparation of drugs. Two drugs are bioequivalent if they are for the same intent and purpose. Bioequivalence is very significant in the development of pharmaceuticals. It matches the set standards to ensure the therapeutic performance of the drug that has undergone several processes from manufacturing until it reached the market is good.

7. What Causes the Different Phases of Trials to Fail?

Phase I trial fails when the pre-clinical model isn’t equivalent to human behavior, or there is insufficient pre-clinical data or extra toxic drug in humans. It can also fail when there is a shift in drug formulation from pre-clinical testing to clinical testing. Phase II and III trial fails due to drug interaction, drug-disease interaction, economic, infrequent ADRs and insufficient effectiveness.

8. What Does the Declaration of Helsinki State?

The Helsinki declaration describes the rules for research, clinical care, and non-therapeutic research. The rules are that:

  • Risk should never outdo benefits
  • Only medically scientifically qualified individuals should conduct research
  • Researchers should base research on human beings on the results from animal and laboratory experiments
  • Independent committee should review research protocols before initiation

9. What are the Objectives of Ich?

The primary goal of Ich is to give recommendations on various ways to attain greater harmonization in the application and interpretation of technical guidelines and requirements for product registration. It aims at reducing the need to duplicate the tests conducted during the research and development of new medicines.

10. What are the Participants of Pharmacovigilance?

The participants include patients, doctors, nurses, pharmaceutical companies, and importing and distributing companies. The patients are the core consumers of the medicine. Doctors, nurses, and other health care practitioners are responsible for monitoring the safety standards of the medicines.

11. What is the Importance of Pharmacovigilance?

Pharmacovigilance is important in limiting the illegal sale of medicines and drugs of abuse over the internet. It also curbs increased self-medication, and increased use of traditional medication outside the borders of traditional practices use. Besides, pharmacovigilance reduces the increased use of different system medications with the potential for drug interaction.

12. What is Ib?

The investigator brochure (Ib) is a primary document which the clinical manager needs for clinical trials concerning FDA regulations. Ib contains:

  • The formulation and description of the drug substance.
  • Summary of the toxicological and pharmacological effects.
  • Summary of information relating to its safety and effectiveness in humans
  • Describes the adverse reaction and possible risks a patient should expect and the investigator’s precautions.

13. What is Protocol Document?

A protocol document defines the objectives, methodology, design, statistical considerations, and clinical trial organization. It permits researchers at multiple locations to research in the same manner to allow a combination of their data as if they did the study in the same location. Moreover, the protocol document gives the research administrators and the local researchers a common reference document for their roles during the trial.

14. What is an Audit Trail?

The audit trail refers to the data that shows the study was carried out following the accepted protocols. It mentions who, why, and when the changes in the data take place. It can also be referred to as documentation that permits the reconstruction of the course of events, according to the Society for Clinical Data Management (SCDM). Audit trails are vital in ensuring visibility in developing a system to an accurate review of the historical security and ensures the information is secure and can’t get in the hands of unauthorized personnel.

15. Describe the Process of Discrepancy Resolution

The discrepancy management team resolves the discrepancy resolution using Data Clarification Form (CDF) or the Data Query Form (DQF). The team generates DCF and sends it to the site investigator for clarification. The investigator receives the corrected values as a response to the CDF and updates them in the database. Lastly, the investigator locks the database to prevent further unauthorized modifications after he has crosschecked the data for errors.
