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.

Who should consider this trial

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

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.

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