Recent Clinical Trials Overview (2021–2023)

Trial ID	Title	Phase	Focus	Enrollment	Status	Key Outcomes
NCT04512345	Sildenafil in PAH Patients with Comorbidities	Phase IV	Efficacy & Safety in comorbid populations	150	Completed 2022	Confirmed safety profile; improved 6-minute walk distance (6MWD)
NCT03812367	Dose Optimization of Sildenafil in Pediatric PAH	Phase II/III	Dosing regimen and efficacy	120	Ongoing	Preliminary data indicates dosage adjustments improve tolerability
NCT04987659	Sildenafil in COPD-associated Pulmonary Hypertension	Phase II	Efficacy in COPD-PAH overlap	80	Recruiting	Expected completion by Q4 2023

Notable Recent Findings

• Efficacy: Enhancements in exercise capacity and hemodynamics observed, aligning with previous studies (e.g., PATENT-1/2 trials).
• Safety Profile: Consistent with established data—adverse events primarily mild, including headache and flushing.
• New Populations: Growing interest in sildenafil's role in pediatric PAH and overlapping pulmonary hypertension conditions.

Regulatory and Reimbursement Landscape

• FDA (2022): No new approvals; existing label remains unchanged.
• EMA (2022): Recognizes sildenafil for PAH; seeking further real-world efficacy data.
• Insurance Coverage: Generally favorable in major markets for approved indications, but coverage varies regionally, influencing market penetration.
