Drs. Mike and John Fralick dive into the top randomized controlled trials of 2024. They highlight finerenone’s impact on heart failure outcomes and discuss innovative uses of tirzepatide for obstructive sleep apnea and liver conditions. Semaglutide’s positive effects on kidney health in diabetes patients also takes center stage. The hosts review findings on antibiotic durations for bloodstream infections, revealing shorter treatment might be just as effective. They wrap up with thoughts on the importance of credible data and community engagement.

Quick takeaways
Finerenone significantly reduces heart failure and cardiovascular deaths in patients with preserved ejection fraction, though its interaction with SGLT2 inhibitors remains uncertain.
Terzepatide effectively treats obstructive sleep apnea and obesity by significantly improving the apnea-hypopnea index and promoting substantial weight loss, despite potential biases in the trial design.
Deep dives
Finerenone's Impact on Heart Failure Management
Research indicates that finerenone can effectively reduce morbidity and mortality in adults suffering from heart failure with preserved ejection fraction. In a double-blind placebo-controlled trial involving 6,000 participants, those taking finerenone experienced a 6% absolute risk reduction in worsening heart failure events and cardiovascular deaths, compared to those on a placebo. The trial highlighted that 36% of finerenone users faced adverse outcomes, contrasting with 42% in the placebo group, primarily driven by decreased heart failure events. However, the trial's limitation lies in the low concurrent use of SGLT2 inhibitors, leaving it uncertain if their combination would yield superior results.
Terzepatide's Efficacy for OSA and Obesity
Terzepatide has shown promising results in treating adults with obstructive sleep apnea (OSA) and obesity, demonstrating significant reductions in the apnea-hypopnea index (AHI). In two phase three trials, participants receiving terzepatide experienced a decrease of 25.3 events per hour in AHI at one year, while the placebo group only saw a reduction of 5.3 events. Furthermore, patients treated with terzepatide lost 18 to 20% of their body weight, which also correlated with improved quality of life metrics. Nevertheless, the studies had limitations, including reliance on data analyzed by employees of the drug sponsor and a lack of long-term follow-up.
Semaglutide's Role in Chronic Kidney Disease
Semaglutide offers beneficial effects in slowing the progression of chronic kidney disease in patients with type 2 diabetes. A randomized trial revealed a 4% absolute risk reduction in major kidney disease events among those receiving semaglutide compared to placebo, with a relative risk reduction of 25%. Key outcomes indicated that patients on semaglutide experienced a better glomerular filtration rate (GFR) by the trial's conclusion. However, concerns persist regarding the clinical relevance of the composite outcome, particularly with the limited use of SGLT2 inhibitors, raising questions about the potential synergy between these medications.
