A 24-week Randomized Placebo-controlled, Double-blind Multi-center Clinical Trial Evaluating the Efficacy and Safety of Oral QTI571 as an add-on Therapy in the Treatment of Severe Pulmonary Arterial Hypertension: Imatinib in Pulmonary Arterial Hypertension, a Randomized, Efficacy Study (IMPRES)

A multinational, multicenter, double blind, placebo-controlled study evaluating the efficacy
and safety of imatinib as an add-on therapy in the treatment of patients with severe
pulmonary arterial hypertension (PAH).


Key Inclusion criteria

- Male or female patients ≥18 years of age with a current diagnosis of pulmonary
arterial hypertension (PAH) according to the Dana Point 2008 Meeting: World Health
Organization (WHO) Diagnostic Group I, idiopathic or heritable (familial or sporadic)
PAH, PAH associated with collagen vascular disease including systemic sclerosis,
rheumatoid arthritis, mixed connective tissue diseases, and overlap syndrome. PAH
following one year repair of congenital heart defect [Atrial Septal Defect (ASD),
Ventricular Septal Defect (VSD) or Posterior Descending Artery (PDA)], or PAH
associated with diet therapies or other drugs

- A Pulmonary Vascular Resistance (PVR) ≥ 800 dynes.sec.cm-5 (as assessed by Right
Heart Catheterization (RHC) at screening or in the 3 months preceding the screening
visit) despite treatment with two or more specific PAH therapies, including
Endothelin Receptor Antagonists (ERAs), phosphodiesterase 5 inhibitors (PDE5), or
subcutaneous, inhaled, intravenous or oral prostacyclin analogues for ≥ 3 months.
Background therapy doses were to be stable for ≥ 30 days except for warfarin and
prostacyclin analogues ( ≥ 30 days but doses could vary even within the month before
enrollment).

- World Health Organization functional Class II-IV. For WHO Functional Class IV, one of
the 2 or more specific PAH therapies were to be an inhaled, subcutaneous, intravenous
or oral prostacyclin analogue, unless the subject showed intolerance of prostacyclin
analogues.

- 6MWD ≥ 150 meters and ≤ 450 meters at screening. Distances of two consecutive 6MWTs
were to be within 15% of one another.

Key Exclusion criteria

- With a pulmonary capillary wedge pressure > 15 mm Hg to rule out PAH secondary to
left ventricular dysfunction.

- With a diagnosis of pulmonary artery or vein stenosis

- Left ventricular ejection fraction (LVEF) < 45%

- With Disseminated Intravascular Coagulation (DIC)

- With evidence of major bleeding or intracranial hemorrhage

- With a history of elevated intracranial pressure

- With a history of latent bleeding risk such as diabetic retinopathy, gastrointestinal
bleeding due to gastric or duodenal ulcers, or colitis ulcerosa

- With a QTcF > 450 msec for males and > 470 msec for females at screening and baseline
in the absence of right bundle branch block.

- With a history of ventricular tachycardia, ventricular fibrillation or ventricular
flutter

- With a history of Torsades de Pointes

- With a history of long QT syndrome

- Having undergone atrial septostomy in the 3 months prior to the screening visit
