Blood Pressure Management: Fresh Drug Proves Effective in Hypertension Control
Taming the Beast: Revolutionary Treatment for Unyielding Hypertension
In an astounding global study, lorundrostat, a novel aldosterone synthase inhibitor, has demonstrated its prowess, safely and consistently reducing high blood pressure in an extensive, diverse patient group, many of whom had previously failed to respond to other medications.
Blood pressure entails the force exercised by blood against the inner walls of the arteries. Hypertension, or abnormally high blood pressure, is a pressing global issue that significantly heightens the risk of heart disease, heart attacks, and strokes.Resistant hypertension is a formidable type of high blood pressure that remains refractory to treatment, despite the use of three different blood pressure medications at their maximum recommended doses. A significant proportion, up to 15%, of individuals experiencing hypertension have anomalous regulation of aldosterone, a hormone that impacts blood pressure regulation. When aldosterone levels are awry, it can trigger hypertension.
Recent research, divulged at the 34th European Meeting on Hypertension and Cardiovascular Protection, reveals that lorundrostat - a drug that impedes aldosterone synthase - proves both secure and effective in tackling uncontrolled or resistant hypertension. As of yet, the findings have not been published in a scholarly journal.
Lorundrostat selectively targets CYP11B2, the enzyme responsible for aldosterone production, thereby lowering aldosterone levels in the body. The study unveiled reductions in blood pressure across a large and multifaceted patient population. This represents the largest phase three trial for this class of treatment to date.
Manish Saxena, MD, the Lead Investigator of the study and Clinical Co-Director of the William Harvey Heart Centre at Queen Mary University of London, spoke to Medical News Today.
"Worldwide, more than half of adults with hypertension fail to achieve their blood pressure goals," Saxena stated. "Aldosterone pathways play a substantial role in blood pressure regulation, leading to complications such as heart failure and kidney problems. In the Launch-HTN trial, we explored the safety and effectiveness of lorundrostat, a novel class of drugs called aldosterone synthase inhibitors. By blocking aldosterone production from the adrenal glands, these drugs have promising potential for treating patients with hard-to-treat blood pressure."
Lorundrostat's Safety and ImpactThe Launch-HTN trial included adult participants whose blood pressure remained uncontrolled despite taking two to five antihypertensive medications. Designed to mirror real-world clinical practice, the trial utilized automated office blood pressure (AOBP) measurements and permitted participants to keep their existing treatments.
Lorundrostat, administered once daily at a 50 mg dose, resulted in meaningful and sustained reductions in systolic blood pressure, with a drop by 16.9 mmHg at Week 6 (a 9.1 mmHg reduction compared to placebo) and by 19 mmHg at Week 12 (an 11.7 mmHg reduction versus placebo).
Saxena went on to emphasize the significance of the results, "The LAUNCH-HTN trial demonstrated blood pressure lowering efficacy and safety of lorundrostat in a very diverse patient group with uncontrolled and difficult-to-treat hypertension that were on background 2-5 blood pressure-lowering medications. The blood pressure reduction observed was consistent across key sub-groups, significant, and clinically meaningful."
A New Weapon against Hypertension
Two additional experts, uninvolved in the study, provided their insights on the findings to MNT.
Cheng-Han Chen, MD, a board-certified interventional cardiologist and the Medical Director of the Structural Heart Program at MemorialCare Saddleback Medical Center in Laguna Hills, CA, highlighted the significance of lorundrostat's aldosterone synthase inhibitor capabilities.
"Aldosterone synthase inhibitors constitute a new class of drugs under investigation for the treatment of hypertension," Chen explained. "This trial demonstrates that lorundrostat, one of these new types of drugs, is safe and effective for patients with uncontrolled or resistant hypertension. This brings us one step closer to adding another weapon to our arsenal for patients with difficult-to-control blood pressure despite being on multiple medications."
Rigved Tadwalkar, MD, FACC, a consultative cardiologist, and the Director of Digital Transformation at Pacific Heart Institute in Santa Monica, CA, further underscored the importance of lorundrostat.
"This is a substantial advancement," Tadwalkar stated. "We still face a sizable number of patients with uncontrolled or resistant hypertension despite being on three, four, or even five medications. Aldosterone is a prevalent impetus in such cases, yet until now, we have lacked a means to directly target this mechanism safely and effectively. Lorundrostat appears to address this gap. By obstructing aldosterone synthesis at the enzymatic level, it seems to do so with a beneficial safety profile and consistent effectiveness across a varied population."
The blood pressure reductions - nearly 17 mmHg at six weeks and close to 19 mmHg at 12 weeks - are substantial, particularly given that these were already heavily treated patients.
Tadwalkar concluded by remarking that while lorundrostat has proven its significance, additional research is required to fully understand its potential and optimize its usage.
"Since patients remained on their background medications, these results feel more clinically relevant than more tightly controlled washout studies. It's a promising addition to the field, even as we continue to grapple with limitations in existing therapies, including newer device-based approaches like renal denervation," Tadwalkar noted.
Ultimately, Saxena expressed optimism for lorundrostat's potential to revolutionize the treatment of hypertension. "Once lorundostat becomes available commercially, it could offer a novel treatment option for hypertension for many patients," Saxena said.
Enrichment Data:Lorundrostat is a groundbreaking drug in development for treating hypertension by acting as an aldosterone synthase inhibitor (ASI). Here's how it functions:
Mechanism of Action
Lorundrostat targets aldosterone production, a hormone that plays a pivotal role in regulating blood pressure. Aldosterone promotes sodium retention and potassium excretion by the kidneys, which in turn leads to increased blood volume and blood pressure. By blocking the synthesis of aldosterone, lorundrostat diminishes the amount of this hormone in the body, thereby reducing sodium retention and lowering blood pressure.
Clinical Efficacy
In both Phase II and III clinical trials, lorundrostat has demonstrated substantial effectiveness in decreasing blood pressure in patients with uncontrolled or resistant hypertension. For instance, in the Phase II trial, patients noted an average reduction of 15 points in systolic blood pressure, with 42% achieving controlled blood pressure levels after 4 weeks. In the Phase III Launch-HTN trial, lorundrostat resulted in sustained reductions in systolic blood pressure, with a drop of 16.9 mmHg at six weeks and 19 mmHg at 12 weeks.
Safety Profile
Although lorundrostat's safety profile has generally shown to be favorable, potential side effects such as increased potassium levels (hyperkalemia) and reduced kidney function have been reported. However, these side effects are typically manageable and are consistent with aldosterone inhibition-related effects.
The implications of lorundrostat extend beyond hypertension treatment, as it could potentially revolutionize the management of other chronic diseases that share similar underlying mechanisms.
