- Study result signals potential kidney benefit with RLX030;1 future studies will further explore this impact
- Kidney dysfunction affects approximately 30 percent of US heart failure patients and is associated with worse prognosis of these patients2
- Data presented at a late-breaking session at the 17th annual Heart Failure Society of America (HFSA) Scientific Meeting in Orlando, Fla.
East Hanover, September 23, 2013 – Novartis today announced new data from a study in chronic heart failure patients assessing the effects of RLX030 (serelaxin) on renal hemodynamics, which included co-primary end points of renal plasma flow (RPF: amount of blood reaching the kidneys) and glomerular filtration rate (GFR: how fast blood is being filtered through the kidneys).1 Results demonstrated there was a statistically significant improvement in RPF in patients taking RLX030 (n=39) compared to placebo (n=48), and there was no statistically significant difference in GFR change. Results also showed RLX030 infusion was well tolerated.1
The kidneys filter blood and remove excess fluid and waste.3 Heart failure, a condition where the heart cannot pump enough blood to the body,4 may decrease RPF. Decreased RPF can initiate a cascade of damage and ultimately lead to reduced kidney function.5 Certain standard of care treatments for heart failure (eg, diuretics) can also contribute to the worsening of kidney function in some patients, making it challenging for physicians to optimally treat this condition at present.5
“Approximately 30 percent of heart failure patients also suffer from kidney dysfunction, an indicator for adverse outcomes,” said Javed Butler, MD, Professor of Medicine and Director, Heart Failure Research at Emory University. “This study is of particular interest because it showed a positive impact on the kidneys. Further studies are needed to establish the relationship of the renal hemodynamic effects seen in this study of stable patients with chronic heart failure to those in patients with acute heart failure.”
RLX030 is currently under review by the US Food and Drug Administration (FDA) for acute heart failure.
Study details1
This was a randomized, double-blind, exploratory study, designed to assess the effects of RLX030 on renal hemodynamics. Patients with chronic heart failure and mild to moderate renal dysfunction received RLX030 or a placebo infused intravenously for 24-hours. The study had two co-primary end points, assessing the effects of RLX030 compared to placebo on renal plasma flow (RPF) in patients and on glomerular filtration rate (GFR), over 8–24 hours after start of infusion.
The results showed RPF increased from baseline over 8–24 hours by 29% in the RLX030 group and 14% in the placebo group. Compared with placebo, RLX030 increased RPF over 8–24 hours by 13% (p=0.0386). There was no statistically significant treatment difference for the co-primary endpoint of GFR change from baseline over 8–24 hours.
Observed as one of the secondary end points in this trial, RLX030 resulted in a 16% relative reduction in filtration fraction (a measure of how hard the kidneys are working) over 8–24 hours, compared with placebo. Filtration fraction is the ratio of GFR to RPF and is a measure of renal work, which is elevated in heart failure.
RLX030 was well tolerated by the patients treated in this study, with slightly fewer patients reporting adverse events (n=8; 20.5%) compared with the placebo group (n=12; 25.0%). The most common AE seen in previous clinical trials (hypotension/blood pressure decrease) occurred in 2 RLX030 patients versus 1 patient in the placebo group.
About RLX030
RLX030 is a recombinant form of a naturally occurring hormone (human relaxin-2), present in both men and women, although its levels rise in pregnant women to help the body cope with the additional cardiovascular demands during pregnancy.6
About heart failure
Heart failure is a debilitating and potentially life-threatening condition where the heart cannot pump enough blood around the body.4 An estimated 5.1 million people suffer from heart failure in the US.7 The condition is often fatal when patients have one or repeated acute heart failure (AHF) episodes.8,9 As an AHF episode approaches, patients become severely breathless and incapacitated and may rapidly gain weight due to fluid build-up in the lungs and around the body.9
Patients experiencing an AHF episode usually need to be rushed to the emergency room for urgent treatment. In fact, AHF is the most common cause of hospitalization in patients over 65 years.10
