Riociguat in children with pulmonary arterial hypertension (PAH)

Trial purpose

This study was designed to evaluate the safety, tolerability, pharmacodynamics and pharmacokinetics of riociguat at age-, sex- and body-weight-adjusted doses of 0.5 mg, 1.0 mg, 1.5 mg, 2.0 mg and 2.5 mg TID in children from ≥6 to less than 18 years with pulmonary arterial hypertension (PAH) group 1. The study design consisted of a main study part followed by an optional long-term extension part. The main treatment period consisted of two phases: titration phase up to 8 weeks and a maintenance phase up to 16 weeks.

Key Participants Requirements

Sex

Both

Age

6 - 17 Years
  • - Children from 6 years to less than 18 years of age with pulmonary arterial hypertension (PAH)
    - Diagnosed with PAH :
     -- Idiopathic (IPAH)
     -- Hereditable (HPAH)
     -- PAH associated with (APAH)
     --- Connective tissue disease
     --- Congenital heart disease with shunt closure more than 6 months ago (no open shunts, confirmed by RHC no less than 4 months after surgery)
    Regardless of the type of PAH, the following findings are not exclusionary:
     --- Patent foramen ovale (PFO) and asymptomatic, isolated, ostium secundum
    atrial septal defect (OS-ASD) ≤ 1 cm (both confirmed by echocardiogram) and not associated with hemodynamic alterations indicative of significant shunt, e.g. Qp/Qs ratio less <1.5:1 are not exclusionary
    - PAH diagnosed by right heart catheterization (RHC) at any time prior to enrolment (for patients with closed shunts – RHC no less than 4 months after surgery)
    - PAH confirmed by a RHC at any time prior to start of study, with mean pulmonary artery pressure (PAPmean) ≥25 mmHg at rest, pulmonary capillary wedge pressure (PCWP) or left ventricular end-diastolic pressure (LVEDP) ≤15 mmHg, and pulmonary vascular resistance (PVR) >240 dyn•sec•cm^-5 (i.e., ≥3.0 wood units•m^2)
    - Patients must be on standard of care PAH medications, allowing Endothelin Receptor Antagonists (ERA) and/or Prostacyclin Analogues (PCA), for at least 12 weeks prior to baseline visit.
    Two groups of patients will be included:

Primary Outcome

  • Number of participants with any treatment-emergent adverse events
    An adverse event (AE), including AE in relation to a medical device (i.e. Raumedic dosing pipette), is any untoward medical occurrence in a participant administered with a pharmaceutical product and does not necessarily have to have a causal relationship with this treatment. A serious AE (SAE) is any untoward medical occurrence that at any dose is resulting in death, is lifethreatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity. AEs occurring between start of study drug and up to 2 days after the last dose were defined as treatment-emergent AEs (TEAEs).
