Dual Endothelin Receptor Antagonism in Large Vessel Vasculitis (DERAIL-LVV)

Large vessel vasculitis is a disease that causes damage to blood vessels. This damage to blood vessels can increase the risk of patients with LVV developing cardiovascular disease, including heart attacks and strokes. A chemical produced in the body called endothelin may contribute to this increase in cardiovascular disease risk by causing the vessels to stiffen and blood pressure to increase.
It has previously been shown that by blocking the effects of endothelin, vessel stiffness and blood pressure improve. Bosentan is a tablet that blocks the effects of endothelin. The investigators plan to assess blood vessel function in those with LVV and participants without LVV. Participants with LVV will then be given Bosentan for 6 weeks to evaluate its impact on blood vessel function.

Pressing Update: Aprocitentan for the Treatment of Hypertension

Review

Author: Whitner, Chardae ; Vascimini, Angelina ; Huston, Jessica ; St. Onge, Erin ; Phillips, Bradley

Objective::

This article reviews the published data including the pharmacology, efficacy, and safety of aprocitentan, a novel endothelin receptor antagonist developed to treat hypertension in conjunction with additional agents.

Data sources::

A literature search was conducted from drug discovery until May 2024 through PubMed, MEDLINE, and National Institutes of Health Clinical Trials Registry utilizing the following search terms: Tryvio, aprocitentan, hypertension, resistant hypertension, endothelin receptor antagonist, and ACT-132577.

Study selection and data extraction::

All relevant English-language studies, or studies that could be appropriately translated into English, containing the pharmacology, pharmacokinetics, safety, and efficacy of aprocitentan, were selected for review.

Data synthesis::

In the setting of resistant hypertension, aprocitentan has shown significant reductions in blood pressure in both medical office and 24-hour ambulatory settings at 4 weeks with a sustained effect at 40 weeks. Studies evaluating cardiovascular risk reduction have not been conducted at this time. Fluid retention and edema were the most frequent adverse events reported in clinical studies with aprocitentan. As a class, endothelin receptor antagonists may cause fetal harm; aprocitentan should be used with caution to avoid embryo-fetal toxicity.

Relevance to patient care and clinical practice in comparison to existing drugs::

Owing to the existent barriers for the treatment of resistant hypertension, aprocitentan presents itself as an effective option when added to traditional antihypertensives. This single-strength, once-daily regimen may serve as an appealing option to both patients and prescribers.

Conclusion::

Aprocitentan is a safe and effective medication for the treatment of hypertension when added to other pharmacological therapies.

Aprocitentan for Blood Pressure Reduction in Black Patients

Article

BACKGROUND::

Black individuals frequently present with resistant hypertension and disproportionately increased cardiovascular risk. We investigated the blood pressure (BP)-lowering effect of the dual endothelin receptor antagonist aprocitentan in Black individuals enrolled in the PRECISION study (Parallel-Group, Phase 3 Study with Aprocitentan in Subjects with Resistant Hypertension).

METHODS::

Patients with confirmed resistant hypertension were randomized to aprocitentan 12.5 mg, 25 mg, or placebo for 4 weeks (part 1). They subsequently received aprocitentan 25 mg for 32 weeks (part 2) before re-randomization to aprocitentan 25 mg or placebo (part 3).

RESULTS::

Eighty-two patients randomized in the PRECISION study were Black individuals. At week 4, aprocitentan 12.5 and 25 mg reduced office trough systolic BP (−11.3 and −11.9 mm Hg) to a similar degree as placebo (−12.0 mm Hg). Using 24-hour ambulatory BP monitoring, the placebo effect was minimal (−0.7 mm Hg), and aprocitentan reduced systolic BP by 4.0 and 8.6 mm Hg. During part 2, office BP continued to decrease (−16.4 mm Hg at week 36). In part 3, office and ambulatory systolic BP increased on placebo (+9.9 and +8.1 mm Hg, respectively), whereas the BP-lowering effect was maintained with aprocitentan. Aprocitentan markedly reduced albuminuria during the study. The most frequent adverse event was peripheral edema, occurring in 3 patients (10%) receiving aprocitentan 25 mg versus none receiving aprocitentan 12.5 mg or placebo.

CONCLUSIONS::

Aprocitentan reduced BP and albuminuria in Black individuals with resistant hypertension. The BP-lowering efficacy was similar to that of the overall PRECISION population. Aprocitentan may represent an important addition to the often difficult-to-control hypertension in Black individuals.

New Therapy Update Aprocitentan: An Endothelin Receptor Antagonist for the Treatment of Drug-Resistant Systemic Hypertension

Review

Author: Frishman, WIlliam H. ; Airo, Michael ; Aronow, Wilbert S.

Resistant hypertension (RH) is the state of uncontrolled blood pressure in the face of ostensibly optimal pharmacological intervention. It accounts for roughly one in six cases of hypertension, and is associated with more severe morbidity and mortality outcomes than is non-RH. The prevalence of RH implies a currently unmanaged pathology, which may involve the potent vasoconstrictor endothelin. Several endothelin receptor antagonists are currently marketed for pulmonary arterial hypertension, but none so far has been marketed for RH. Aprocitentan is currently in development, an endothelin receptor antagonist that effectively produces clinically significant and sustained decreases in systolic and diastolic blood pressure in the setting of RH.

US FDA removes REMS requirement for TRYVIO (aprocitentan) – minimizing the burden on the healthcare delivery systems and patients

Ad hoc announcement pursuant to Art. 53 LR FDA confirms that prescribers and pharmacists are no longer expected to interact with the REMS Allschwil, Switzerland – March 17, 2025Idorsia Ltd (SIX: IDIA) today announced that – effective immediately – the US FDA has fully released TRYVIO™ (aprocitentan) from its REMS (Risk Evaluation and Mitigation Strategy) requirement. TRYVIO is Idorsia’s dual endothelin receptor antagonist (ERA) indicated for the treatment of systemic hypertension in combination with other antihypertensives to lower blood pressure in patients who are not adequately controlled on other drugs. The US FDA has determined that a REMS is no longer necessary to ensure the benefits of TRYVIO outweigh the risk of embryo-fetal toxicity and that labeling is sufficient for conveying the safety information. The FDA have therefore removed the requirement to minimize the burden on the healthcare delivery system of complying with the REMS. Consequently, Idorsia is also released from the post marketing requirement (PMR) to conduct a worldwide descriptive study that collects prospective and retrospective data in women exposed to TRYVIO during pregnancy and/or lactation as these data are no longer needed. Idorsia no longer has post marketing requirements for TRYVIO. Martine Clozel, Chief Scientific Officer of Idorsia, commented:“As a dual endothelin receptor antagonist (ERA), TRYVIO targets a previously unaddressed but important pathway in systemic hypertension, the endothelin pathway. The FDA decision that a REMS is no longer necessary for TRYVIO reflects the progressive understanding of the risk / benefit of TRYVIO. The decision of the FDA is based on an evaluation of human fetal outcomes after exposure to a drug in the ERA class. This change is very important considering that TRYVIO can be prescribed to a large patient population, who have a high cardiovascular risk and whose hypertension could not be brought under control with the previous classes of medication. This comes on top of the outstanding properties of TRYVIO, the result of over 25 years of optimization in our drug discovery team.” Michael Moye, President and General Manager of Idorsia US, commented:“TRYVIO is the first new antihypertensive working via a new pathway for over 40 years. It is a once-daily tablet, is easy to use for patients and easy to prescribe for physicians. In the absence of clinically relevant drug interactions, it can be safely combined with complex drug regimens and, importantly, can be used by chronic renal failure patients with hypertension without dose modification. On top of existing antihypertensives, aprocitentan has been shown to decrease systolic blood pressure by more than 15 mmHg from baseline at trough, and it is well tolerated over the long term. The release of the REMS is fantastic news as it makes TRYVIO even easier to prescribe. TRYVIO is available to prescribe today, and we are now looking for the best commercial solution to fully launch this important medication that fills a large unmet patient need.” Idorsia will submit revised labeling to the US FDA in accordance with the release of the REMS in the coming weeks. For current information on TRYVIO see the Full Prescribing Information including BOXED Warning (PI and Medication Guide). TRYVIO continues to be commercially available through Walgreens Specialty Pharmacy.

Mineralys’ Hypertension Drug Drops Blood Pressure in Phase II/III, Setting Up Market Clash

Tiny doctors examining heart health flat vector illustration. Cartoon medical specialists doing checkup of blood pressure, pulse rate and cholesterol. Cardiovascular disease and cardiology concept BRO Vector/Getty Images Mineralys’ shares got a more than 50% boost Monday morning as new data showed its hypertension drug reduced blood pressure in a pair of clinical trials. Mineralys Therapeutics’ hypertension drug reduced blood pressure in a Phase III trial , sending the biotech’s shares up by more than 50%. But lorundrostat will face a tough market battle, with incumbent Idorsia settling in with a new medicine and several late-stage options coming down the pike. Lorundrostat is an inhibitor of aldosterone synthase, the enzyme responsible for making the steroid aldosterone. Increased amounts of aldosterone have been often linked to rates of hypertension. The pivotal Phase III Launch-HTN and Phase II Advance-HTN trials tested lorundrostat in 1,000 patients with uncontrolled high blood pressure who were already taking two to five antihypertensive drugs. The Phase III trial met its primary goal, assessing the change in systolic blood pressure from baseline compared to placebo after six weeks. Patients who received 50 mg of lorundrostat on top of their preexisting regimens saw a 9.1 mmHg placebo-adjusted drop in blood pressure. Zooming out, at 12 weeks, patients on the lower dose of lorundrostat had an 11.7 mmHg decrease in blood pressure, while patients in the higher dose group had an 8.4 mmHg drop at 12 weeks when adjusted for placebo. As for safety, 4 patients across the two dosing groups reported adverse events that were deemed related to the treatment. Twelve patients in the 50 mg dose group had events such as increased serum potassium, decreased kidney activity, urinary tract infection and hypertension. In the Phase II study, patients with uncontrolled or treatment-resistant hypertension on background therapy saw their blood pressure drop by 7.9 with 50 mg of lorundrostat, meeting the main goal of the study. The primary endpoint of blood pressure reduction was measured using a 24-hour average at week 12. Adverse events were fewer in this study, with two patients reporting AEs, with one report of hyponatremia, which is when sodium levels in the body drop below normal. Mineralys’ shares rose 52% to $16 per share Monday morning after the results were announced. “We believe the clinical pro for lorundrostat supports the potential regulatory approval of this novel agent and its significant commercial value,” Mineralys CEO Jon Congleton said in a statement. The company plans to announce more detailed findings later this month at the American College of Cardiology Scientific Sessions. These results continue a positive trend for Mineralys, which in September 2023 announced positive Phase II data from the Target-HTN trial of lorundrostat, also showing improvements in blood pressure. Monday’s data release also comes after a blizzard of activity in the hypertension space. In March 2024, Idorsia won FDA approval for its hypertension drug Tryvio, an endothelin receptor antagonist, claiming to be the first new mechanism in hypertension treatments in decades. Other companies, including Alnylam and George Medicines , have also announced late-stage anti-hypertension data in the last few months.

Perfuse Therapeutics Announces Positive Visual, Structural and Safety Data from a Ph1/2a Trial of PER-001 in Glaucoma Patients at the American Glaucoma Society Meeting

Twenty-four-week data from the Ph1/2a trial in glaucoma patients reveals PER-001 to be well-tolerated. Proof of concept is established with both strong functional and structural outcomes Glaucoma patients treated with PER-001 on top of IOP reducing therapies experienced a mean improvement in visual field mean deviation of 1 decibel (dB) per year and a mean increase in retinal nerve fiber layer thickness of 3 microns at 24 weeks SAN FRANCISCO, March 3, 2025 /PRNewswire/ -- Perfuse Therapeutics, a biopharmaceutical company pioneering transformational therapies to treat ischemia-induced ocular diseases announced today the presentation of 24-week data from its first-in-human Phase 1/2a trial of PER-001 intravitreal implant in patients with glaucoma. The data was presented by Steven Mansberger, MD, MPH, Chief of Ophthalmology, Director of Glaucoma Services at Legacy Devers Eye Institute, March 1, 2025, at the American Glaucoma Society Meeting in Washington DC. The trial is fully enrolled with glaucoma patients (n=33) receiving a single administration of PER-001 on top of IOP reducing therapies. Data presented included results from the Ph1 (n=6) and Ph2a Dose 1 (n=12) cohorts, both of which completed the trial. The Ph2a Dose 2 (n=15) cohort is ongoing. The 24-week data demonstrated that PER-001 was well-tolerated, with only one drug-related adverse event of vitreous floater (mild and transient), no drug-related serious adverse events and no reports of intraocular inflammation. Patients treated with PER-001 showed a mean increase in optic nerve head blood flow of at least 10% from baseline starting at Week 1, which was sustained out to Week 24 and was associated with a mean improvement in visual field mean deviation of 1 dB/yr and a mean increase in retinal nerve fiber layer thickness of 3 microns, as measured by optical coherence tomography (OCT) at Week 24. In contrast, the sham control group revealed a 0.63 dB/yr decline in visual field mean deviation and a decrease of 1.3 microns in OCT RNFL at Week 24. "These results are distinctive and noteworthy," stated Steven Mansberger, MD, MPH. "There remains an unmet need for neuroprotective therapies for patients with glaucoma and while this is early data, the observed improvements in the optic nerve head blood flow, as well as key functional and structural outcomes are very promising." "We are excited to share first-in-human data from the ongoing PER-001 trials," said Sevgi Gurkan, MD, CEO and Founder. "Endothelin is a well-established, clinically validated pathway with many approved products in systemic diseases. The Ph1/2a trial marks the first ever clinical application of an endothelin antagonist for local treatment of back of the eye diseases, and we are encouraged by the safety profile and efficacy data to date." "Glaucoma is the leading cause of irreversible blindness worldwide, and there are no currently approved therapies. This trial provides the first clinical validation of the key role of endothelin pathway in glaucoma. The results of this trial are highly encouraging and the data supports the potential of PER-001 intravitreal implant as a disease-modifying therapy that could significantly improve the vision and lives of glaucoma patients," said Phil Lai, MD, Chief Medical Officer. About PER-001 Intravitreal Implant, a Long Acting Endothelin Receptor Antagonist PER-001 is a novel (NCE), first-in-class small molecule endothelin receptor antagonist. Endothelin is the most potent vasoconstrictor in the human body and is upregulated in glaucoma. Endothelin is involved in inflammation and cell death through its receptors expressed in retinal vascular and neuroretinal cells. The PER-001 intravitreal implant is a bio-erodible implant, administered into the vitreous cavity of the eye using a single use, 25-gauge applicator and designed to provide a sustained release of PER-001, allowing for a convenient every 6 months dosing frequency. About the Ph1/2a Trial The Phase 1/2a trial is a multi-center two-part trial designed to assess the safety, tolerability and pharmacodynamics of PER-001 in glaucoma patients. The Phase 1 part of the trial was a first-in-human, open-label, single ascending dose (SAD) study that evaluated the safety and tolerability of two doses of PER-001 intravitreal implant in patients with advanced glaucoma. The Phase 2a part of the trial was a patient and reading center masked, randomized, sham-controlled study that evaluated the safety, tolerability, and pharmacodynamics of two doses of PER-001 in patients with progressing, mild to moderate glaucoma. Patients in both phases received a single intravitreal administration of PER-001 while maintaining their pre-study IOP-lowering therapies. Two doses of PER-001 intravitreal implant were tested sequentially in cohorts of 3 patients each during the Ph1 SAD portion and the same two doses were subsequently tested in a larger cohort of patients during the Ph2a portion of the trial. All patients were followed for 24 weeks from their first and single dose. The Ph1 cohorts and Ph2a Dose 1 cohort have completed the trial. Ph2a Dose 2 cohort is ongoing and the topline data will be available in second quarter 2025. About Perfuse Therapeutics, Inc.
