Not applicable Interventional University of Sao Paulo General Hospital · NCT06850792

This study will try whether regular telemedicine check-ins and guided education help people with PAH stick to their oral medications and manage side effects.

What this trial studies

OPENLINE is a randomized, multicenter trial testing a structured telemedicine intervention to improve medication adherence in adults with Group 1 PAH on stable oral therapy. Participants randomized to the intervention receive biweekly teleconsultations for six months focused on patient education, adherence monitoring, and side-effect management, while the control group receives standard clinical care. The primary outcome is medication adherence measured by the Martín-Bayarre-Grau (MBG) scale, and secondary outcomes include WHO functional class, six-minute walk distance, BNP levels, COMPERA 2.0 and REVEAL Lite risk scores, hospitalizations, mortality, and quality of life by CAMPHOR. The study is conducted at InCor - Universidade de São Paulo and requires participants to have access to a phone or internet for remote visits.

Who should consider this trial

Good fit: Adults (≥18 years) with WHO Group 1 PAH who have been on stable oral PAH therapy for at least four weeks, can use phone or internet for teleconsultations, and can give informed consent.

Not a fit: Patients unlikely to receive benefit include those with severe cognitive or psychiatric disorders, inability to use telemedicine, participation in conflicting interventional trials, limited life expectancy (<6 months), pregnancy or breastfeeding, or those not on stable oral therapy.

Why it matters

Potential benefit: If successful, this approach could increase medication adherence, reduce hospital admissions, and improve quality of life for people with PAH.

How similar studies have performed: Telemedicine and remote-monitoring programs have shown mixed but often positive effects on medication adherence in chronic diseases, though randomized data specific to PAH are limited.

Eligibility criteria

Exclusion Criteria:

* Severe cognitive impairment or psychiatric disorders that could affect adherence or study participation.
* Inability to communicate via phone or telemedicine due to technical or personal constraints.
* Concurrent participation in another interventional clinical trial that could interfere with outcomes.
