Hypertension remains the most common treatable cardiovascular risk factor globally, yet blood pressure control rates remain suboptimal despite multiple effective drug classes. Clinical trials now investigate novel mechanisms including aldosterone synthase inhibitors, renal denervation devices, and RNA-based therapies targeting angiotensinogen to achieve durable pressure reduction with minimal pill burden.
Active research includes zilebesiran (RNA interference targeting angiotensinogen), baxdrostat (aldosterone synthase inhibitor), ultrasound renal denervation (Symplicity HTN-4), and resistant hypertension approaches combining SGLT2 inhibitors with MRA spironolactone. Ambulatory blood pressure monitoring is increasingly used as the primary endpoint instead of clinic readings.
Frequently Asked Questions — pulmonary arterial hypertension pah Clinical Trials
How many clinical trials are currently recruiting for pulmonary arterial hypertension pah?
ClinicalMetric currently tracks 4 actively recruiting clinical trials for pulmonary arterial hypertension pah, sourced in real time from ClinicalTrials.gov. The total number of registered studies—including those not yet enrolling or in active follow-up—is 4. Trial availability changes daily as new studies open enrollment and existing ones reach capacity.
What trial phases are available for pulmonary arterial hypertension pah?
pulmonary arterial hypertension pah research spans Phase 3 (1 trial). Phase 1 studies evaluate safety and dosing in small groups, Phase 2 studies assess preliminary efficacy in 100–300 participants, and Phase 3 trials compare the new treatment against the standard of care in 300–3,000+ patients. Phase 4 post-approval studies monitor long-term outcomes in real-world populations.
How do I find out if I qualify for a pulmonary arterial hypertension pah clinical trial?
Eligibility criteria for pulmonary arterial hypertension pah trials vary by study and typically specify age range, disease stage or severity, prior treatment history, and specific diagnostic or laboratory parameters. Each listing on ClinicalMetric links to the full protocol on ClinicalTrials.gov, where inclusion and exclusion criteria are documented.
