What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the safety and effectiveness of lorundrostat for individuals with high blood pressure. Lorundrostat blocks a chemical in the body that raises blood pressure. Participants will receive either lorundrostat or a placebo (a pill with no active medicine) to assess its long-term effects. This trial suits those who have already participated in a lorundrostat study and completed the previous phases. As a Phase 3 trial, it serves as the final step before FDA approval, providing participants an opportunity to contribute to the potential availability of a new treatment.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications, but it mentions that certain medications are prohibited. It's best to discuss your current medications with the study team to see if they are allowed.

Is there any evidence suggesting that lorundrostat is likely to be safe for humans?

Research has shown that lorundrostat is generally safe for people with high blood pressure. Studies have found that it effectively lowers blood pressure both in the doctor's office and throughout the day. Importantly, these studies also indicate that lorundrostat has a good safety record. Participants experienced fewer side effects compared to those taking a placebo, a non-active substance used for comparison.

In one study, lorundrostat reduced the top number in a blood pressure reading by about 7 to 8 points, with a low risk of side effects. The treatment did not cause major problems, suggesting it is quite safe for most people. These findings may reassure those considering joining a trial about the treatment's safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for high blood pressure?

Unlike the standard high blood pressure treatments, which often include ACE inhibitors, beta-blockers, or diuretics, lorundrostat stands out because it targets a different pathway. Researchers are excited about lorundrostat because it inhibits aldosterone synthase, potentially offering a more precise way to manage high blood pressure. This novel mechanism could mean fewer side effects associated with traditional blood pressure medications, making it a promising option for patients who struggle with current treatments.

What evidence suggests that lorundrostat might be an effective treatment for high blood pressure?

Previous studies have shown that lorundrostat holds promise for lowering high blood pressure. Research indicates that lorundrostat led to larger drops in average blood pressure compared to a placebo. Specifically, one study found that 42% of patients taking lorundrostat had their blood pressure under control in just four weeks, compared to only 19% with a placebo. Additionally, lorundrostat significantly reduced the chances of experiencing very high blood pressure events. These findings suggest that lorundrostat could effectively manage high blood pressure. Participants in this trial will receive lorundrostat in different study arms, including an open-label arm and a double-blind randomized treatment withdrawal substudy. ^{1 2 3 4 6}

Trial Overview

The trial is testing the long-term effects of lorundrostat on people with high blood pressure. It aims to assess how safe and effective it is over time compared to a placebo (a substance with no active drug).

How Is the Trial Designed?

Group I: RTW Substudy Experimental Treatment 2 Interventions

lorundrostat or placebo once daily for 4 weeks starting at week 12, in the double-blind randomized treatment withdrawal substudy Optional for subjects from the MLS-101-301 parent study only

Group II: Optional Continuation Period Experimental Treatment 1 Intervention

lorundrostat once daily from week 52 or until marketing authorization or early termination of the trial by the sponsor

Group III: Open-Label Arm Experimental Treatment 1 Intervention

lorundrostat once daily for 52 weeks depending on when the subject enrolled

Published Research Related to This Trial

Baxdrostat, a selective aldosterone synthase inhibitor, was found to be safe and well-tolerated in a study of 54 healthy volunteers, with no serious adverse events reported and only mild side effects observed.

The study demonstrated that baxdrostat effectively reduced plasma aldosterone levels by 51 to 73% after 10 days of treatment at doses of 1.5 mg or higher, while having no significant impact on cortisol levels, indicating its selective action.

Baxdrostat (CIN-107) is a selective aldosterone synthase inhibitor being tested as a treatment for drug-resistant hypertension, which is linked to serious cardiovascular issues.

While a phase 2 trial (BrigHTN) showed promising efficacy results, the HALO trial found no significant blood pressure-lowering effect of baxdrostat compared to placebo, indicating the need for further studies to assess its effectiveness.

In a study involving 27 healthy volunteers, the co-administration of baxdrostat with metformin was found to be safe, with no serious adverse events or significant increases in side effects, indicating good tolerance of the combination.

Baxdrostat did not significantly alter the plasma levels or renal clearance of metformin, suggesting that diabetic patients with hypertension can take both medications without needing to adjust the metformin dose.
