Opportunity Information: Apply for RFA FD 14 024
The government grant opportunity titled "Pharmacokinetic and Pharmacodynamic (PK PD) Studies of Cardiovascular Drugs (U01)" aims to address concerns regarding the bioequivalence and therapeutic equivalence of metoprolol, a selective beta-1 receptor blocker commonly used to treat cardiovascular diseases such as hypertension. Metoprolol is primarily metabolized by the CYP2D6 enzyme, which varies among individuals due to genetic differences. Variations in the drug's formulations—such as salt forms and dosage types—can lead to differing pharmacokinetic (PK) profiles and potential therapeutic effectiveness.
The FDA has observed issues when patients switch from brand-name to generic metoprolol, including reports of ineffectiveness and adverse events. As the agency has not reached definitive conclusions on these concerns, there is a pressing need for PK/PD studies in patients to elucidate the intricacies of metoprolol's performance.
The objectives of the proposed study are to conduct a prospective PK/PD analysis involving hypertensive patients to establish relationships between drug pharmacokinetics and its pharmacodynamic effects. Key study goals include evaluating the PK/PD relationship, assessing the impact of treatment changes (specifically switching metoprolol products), analyzing variations in pH and delivery rates, and understanding the influence of CYP2D6 genetic variations.
A randomized crossover trial design is recommended, allowing for patients to switch products while maintaining the same dosage. This study will simultaneously collect PK and PD samples to connect PK characteristics with their effects on patients. The research will also focus on enrolling both extensive and poor CYP2D6 metabolizers to better understand how genetic differences affect drug metabolism and efficacy.
In the first year, efforts will concentrate on developing a study protocol for necessary approvals, ensuring product blinding, quality testing, validating bioanalytical methods, and initiating patient enrollment.Apply for RFA FD 14 024
