Efficacy and Safety of Upfront Combination of ΒΟsentan and ΤΑdalafil in Pulmonary Arterial Hypertension (BOTA-PAH)

An Observational, Non-interventional, Multicenter Study to Evaluate the Efficacy and Safety of Upfront Combination of Bosentan and Tadalafil in Pulmonary Arterial Hypertension in Greek Patients
The development of disease-targeted drugs for the treatment of pulmonary arterial hypertension (PAH) has significantly improved within the last years.
Combining drug products with different mechanisms of action such as Endothelin-Receptor-Antagonists (ERAs) and Phosphodiesterase-Type-5-inhibitors (PDE-5-Inhibitors) has become increasingly important for the treatment of PAH.
Recently, the results of the AMBITION study reported that an upfront combination treatment of ambrisentan and tadalafil immediately after diagnosis leads to a delayed disease progression.
On the other hand, the sequential combination of bosentan and sildenafil did not show a similar positive clinical effect and this was attributed to a negative clinically relevant pharmacodynamic drug-drug interaction.
Although, recent guidelines have extrapolated that initial upfront combination treatment follows a class effect in terms of efficacy and safety, there is an imperative need to support this notion with other combinations of ERAs and PDE-5-Inhibitors.

상세 설명
The primary objective of BOTA study is to compare the change in clinical and hemodynamic measures of PAH after the initiation of first line combination therapy with bosentan and tadalafil in adult patients with PAH. The safety and tolerability of first line combination therapy will also be evaluated.
In patients with PAH initial upfront combination treatment with bosentan and tadalafil
Improves
- Exercise capacity as expressed by distance walked in six minute walk test and WHO functional class
- Hemodynamics in terms of pulmonary vascular resistance (PVR), mean pulmonary artery pressure (mPAP) reduction and cardiac index (CI) elevation
- Quality of life
- NTproBNP serum levels
- Echocardiographic prognostic parameters such as right atrial area and presence of pericardial effusion.
Is safe as assessed by
- Liver function markers such as serum SGOT and SGPT levels
- Hemoglobin levels

Change From Baseline in the N-Terminal Pro-B-Type Natriuretic Peptide at Month 6
기간: 6 months
|
N-Terminal Pro-B-Type Natriuretic Peptide (NT-proBNP) is a surrogate marker of heart failure.
The geometric mean ratio will be calculated as the ratio between the month 6 value and the Baseline value and presented as percent change = 100 * (geometric mean ratio - 1).
The Baseline value is the last value prior to administration of study drug; this may be prior to or on the day of study drug initiation.
