Cardiovascular diseases remain a leading cause of morbidity and mortality worldwide. This review highlights ten promising antihypertensive drug candidates with the potential to address pulmonary arterial hypertension (PAH), resistant hypertension and uncontrolled hypertension.

Aprocitentan, developed by Janssen NYSE:JNJ) and Idorsia (SIX:IDIA), is an experimental oral drug designed to treat resistant hypertension. As a dual endothelin receptor antagonist (ERA), it effectively blocks the binding of ET-1 to both ET A and ET B receptors. The drug has a low likelihood of interacting with other medications and its mechanism of action is well-suited for treating resistant hypertension. In clinical trials, aprocitentan demonstrated better blood pressure reduction than placebo, with the effects lasting up to week 40, and was generally well-tolerated by patients.

Merck & Co.’s (NYSE: MRK) sotatercept has received breakthrough therapy status from FDA and reported positive Phase 3 results for PAH pulmonary arterial hypertension (PAH), a life-threatening condition involving high blood pressure in the arteries of the lungs. Additionally, Arena Pharmaceuticals, recently acquired by Pfizer (NYSE:PFE), has demonstrated encouraging Phase 2 results for the antihypertensive ralinepag, which is now in Phase 3 for PAH. This drug candidate could potentially offer a new therapeutic strategy for PAH patients who do not respond well to existing treatments.

Drugs in Phase 2 trials include XXB750 from Novartis (NYSE:NVS), which holds potential for resistant hypertension, a condition that often requires complex and aggressive treatment strategies. This antihypertensive compound may offer a new treatment option for patients who fail to achieve blood pressure control with standard therapies. Also in Phase 2 is Alnylam’s (Nasdaq:ALNY) zilebesiran, which has a novel mechanism of action for hypertension, potentially leading to more effective and personalized treatment options.

In the same category is IONIS-AGT-LRx from Ionis (Nasdaq:IONS), which targets uncontrolled hypertension, a condition where blood pressure remains high despite treatment with medications. This investigational drug aims to improve blood pressure control for patients who have difficulty managing their hypertension. Baxdrostat, CinCor‘s lead asset, is also in Phase 2 for resistant hypertension. AstraZeneca (LON:AZN) acquired the company in February, further bolstering the drug’s prospects for successful development.

In early March, Mineralys Therapeutics announced positive data from its Target-HTN Phase 2 study, showing significant blood pressure reduction in hypertensive patients receiving once-daily lorundrostat. The study supports the hypothesis linking obesity, aldosterone and hypertension. The company believes lorundrostat has the potential for use earlier in the treatment paradigm for hypertension than current therapies.

The table above is based on factors such as clinical trial phases, obtained results, and potential impact on patient populations. We selected the following investigational drugs based on their potential impact in hypertension and PAH management from recent clinical studies. Criteria include the stage of development, target indications, which included PAH and uncontrolled and resistant hypertension. We also considered the novelty of the drug candidates’ mechanism of action as well as company reputation and experience.
