Safety, Pharmacokinetics and Efficacy Study of QCC374 in PAH Patients

Stopped early · Phase 2 · Has a placebo group

Conditions studied: Pulmonary Arterial Hypertension

In brief

This was a non-confirmatory, randomized, placebo controlled, subject and investigator blinded study of QCC374 in PAH subjects. The study was planned to have 2 Parts: Part 1, an initial safety cohort with a 0.03 mg bid starting dose, and Part 2, a larger cohort with a 0.06 mg bid starting dose. However, due to early study termination following Part 1, Part 2 was not completed. Both study parts were comprised of four phases: a screening period for up to 28 days, a titration period of 2 weeks, a stable dose period of 14 weeks and safety follow-up period for 28 days. At the end of the treatment period of 16 weeks, eligible patients were given the option to participate in a separate long-term extension study (CQCC374X2201E1 (NCT02939599)), where all patients were treated with an individual optimal dose of QCC374.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male and female patients 18 years of age or older with symptomatic PAH.
• Subjects with PAH belonging to one of the following subgroups of the Updated Clinical Classification Group 1 (Nice, 2013):
• Idiopathic PAH
• familial PAH
• PAH associated with connective tissue disease, congenital heart disease (surgically repaired at least 12 months prior to screening) or drug or toxin induced (for example, anorexigen use).
• Subjects must have persistent symptoms due to PAH despite therapy with at least one of the following PAH medications: an endothelin receptor antagonist, asoluble guanylate cyclase stimulator or a phosphodiesterase inhibitor. The subjects' PAH medication regimen, with typical medications including calcium channel blockers, endothelin receptor antagonists, soluble guanylate cyclase stimulators and/or phosphodiesterase inhibitors, must have been used at a stable dose and frequency for at least 12 weeks before the screening visit and during the screening period.
• Diagnosis of PAH established according to the standard criteria before the screening visit:
• Resting mean pulmonary arterial pressure > 25 mmHg.
• PVR > 240 dynes s/cm5.
• Pulmonary capillary wedge pressure or left ventricular end diastolic pressure < 15 mmHg
• PVR > 400 dynes s/cm5 at the time of the baseline right heart catheterization (RHC) (if a RHC was completed within one month of the screening visit, that result may be used for inclusion).
• 6-minute walk distance greater than 150 meters at Screening. This distance must be confirmed by a second 6MWT prior to randomization. The value of the second 6MWD should be within ± 15% of the value obtained at Screening.

You may not qualify if…

• Subjects with clinically unstable right heart failure within the last three months (New York Heart Association (NYHA) Class IV).
• Subjects with PAH associated with portal hypertension, Human Immunodeficiency Virus (HIV) infection or unrepaired congenital systemic to pulmonary shunts
• Subjects who have received or have been scheduled to receive long-term treatment with epoprostenol or any prostacyclin within the three months prior to the screening visit or during the screening period.
• Hypotensive subjects (systemic systolic blood pressure < 85 mmHg)
• Subjects with a history of left sided heart disease, chronic left sided heart failure, congenital or acquired valvular disease and/or pulmonary venous hypertension.
• Subjects with significant obstructive (forced expiratory volume in one second [FEV1]/forced vital capacity [FVC] < 70% predicted) or restrictive (total lung capacity < 70% predicted) lung disease at screening.
