CNPR Healthcare Industry Knowledge & Drug Approval Process 3 — Questions and Answers
Question 1: What is a New Drug Application (NDA)?
- A request submitted to Congress to fund drug research
- A formal proposal asking FDA permission to market a new drug in the US (Correct answer)
- A patent application filed with the USPTO for a new chemical entity
- An application submitted to CMS for Medicare drug coverage
Correct answer: A formal proposal asking FDA permission to market a new drug in the US
An NDA is submitted to the FDA after clinical trials are complete, containing all data needed to demonstrate safety and efficacy for marketing approval.
Question 2: Which of the following is a key difference between brand-name and generic drugs?
- Generic drugs undergo no FDA review before approval
- Generic drugs must have the same active ingredient, strength, and route of administration as the brand (Correct answer)
- Brand-name drugs are always more effective than their generic counterparts
- Generic drugs are only approved for over-the-counter use
Correct answer: Generic drugs must have the same active ingredient, strength, and route of administration as the brand
The FDA requires generics to be bioequivalent — same active ingredient, dosage form, strength, and route of administration — but inactive ingredients may differ.
Question 3: What is the role of a Pharmacy Benefit Manager (PBM)?
- To license pharmacists at the state level
- To manage prescription drug benefits on behalf of health insurers, employers, and government programs (Correct answer)
- To set the wholesale price of medications for retail pharmacies
- To conduct post-marketing surveillance of adverse drug events
Correct answer: To manage prescription drug benefits on behalf of health insurers, employers, and government programs
PBMs negotiate drug prices, process claims, and develop formularies on behalf of plan sponsors, making them powerful gatekeepers in pharmaceutical access.
Question 4: Under the Prescription Drug Marketing Act (PDMA), which of the following is a pharmaceutical sales representative required to do with drug samples?
- Sell samples to physicians at a reduced rate
- Maintain accurate records of samples distributed and obtain a licensed practitioner's signature (Correct answer)
- Distribute samples only in hospital settings
- Obtain FDA approval for each sample batch before distribution
Correct answer: Maintain accurate records of samples distributed and obtain a licensed practitioner's signature
The PDMA requires reps to track samples, obtain signatures from licensed practitioners, and maintain records to prevent diversion or fraud.
Question 5: What is the primary goal of Phase III clinical trials?
- To identify the maximum tolerated dose in healthy subjects
- To confirm efficacy and monitor adverse reactions in large patient populations (Correct answer)
- To develop a scalable manufacturing process for the drug
- To establish the pharmacokinetic profile of the drug in animals
Correct answer: To confirm efficacy and monitor adverse reactions in large patient populations
Phase III trials involve hundreds to thousands of patients and are designed to confirm effectiveness and gather safety data needed for NDA submission.
Question 6: Which type of healthcare provider has the legal authority to prescribe Schedule II controlled substances in all 50 states?
- Registered Nurses (RNs)
- Certified Medical Assistants (CMAs)
- Physicians (MDs and DOs) (Correct answer)
- Pharmacy Technicians
Correct answer: Physicians (MDs and DOs)
Licensed physicians hold DEA registration that authorizes them to prescribe Schedule II controlled substances, though Nurse Practitioners and PAs may also have this authority in many states.
Question 7: What does 'market exclusivity' granted by the FDA protect, and how does it differ from a patent?
- It is identical to a patent and prevents all competitors from manufacturing the drug
- It is an FDA-granted period preventing generic approval regardless of patent status, based on regulatory criteria (Correct answer)
- It allows a company to set any price for a drug without government interference
- It restricts a drug to use only within a specific geographic region
Correct answer: It is an FDA-granted period preventing generic approval regardless of patent status, based on regulatory criteria
Market exclusivity is an FDA regulatory protection that blocks generic applications for a set period (e.g., 5 years for new chemical entities), independent of patent protection.
