Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 80 with a confirmed diagnosis of pulmonary hypertension and a CardioMEMS PA Sensor implanted.

Probably not a fit

Patients with pulmonary hypertension due to specific causes like HIV or portal hypertension, or those with significant cardiac disease, may not benefit from this study.

What this trial studies

This phase 2 trial evaluates the safety and tolerability of multiple subcutaneous injections of APL-9796 in adults diagnosed with pulmonary hypertension. The study is divided into two parts, with Part A focusing on patients with WHO Group 1 pulmonary arterial hypertension and Part B optionally including those with WHO Group 3 pulmonary hypertension associated with interstitial lung disease. The trial will also assess the effectiveness of APL-9796 and the body's immune response to the treatment.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients suffering from pulmonary hypertension.

How similar studies have gone: Other studies have shown promise in treating pulmonary hypertension with novel therapies, suggesting potential for success with this approach.
