Brief summary

The purpose of this multicentre, open label, single-arm study in approximately 20 adult patients is to evaluate the Impact on lifestyle of a new thermo stable formulation of epoprostenol sodium in subjects with Pulmonary Arterial Hypertension (PAH).

Detailed description

This is a multicentre, open label, single-arm study in approximately 20 adult patients (18 - 75 years old) designed to evaluate the Impact on lifestyle of a new thermo stable formulation of epoprostenol sodium in subjects with Pulmonary Arterial Hypertension (PAH). The co-primary objectives are 1) to describe the effect of the new thermo stable formulation of epoprostenol sodium on quality of life and 2) to determine the dose titration requirement in patients switching from the currently marketed FLOLAN (epoprostenol sodium) to the new thermo stable formulation. Secondary objectives include assessing the safety, tolerability and efficacy of the thermo stable formulation of epoprostenol sodium and the exploratory objective is to evaluate the effect of the new thermo stable formulation of epoprostenol sodium on haemodynamic parameters in a subset of subjects. Subjects who are already receiving FLOLAN (epoprostenol sodium) for the treatment of PAH and have been on a stable dose for at least 3 months and on stable doses of other PAH treatments for at least 30 days prior to screening will be enrolled. After a screening visit, eligible subjects will have a 4-week run-in period with their existing FLOLAN (epoprostenol sodium) treatment. At the end of the 4-week period, they will be admitted to the clinic for baseline assessments and for switching to study medication (the new thermo stable formulation of epoprostenol sodium). Subjects will remain in hospital for a minimum of 6 hours to ensure clinical and hemodynamic stability prior to discharge. Subjects may stay in hospital for up to 24-48 hours after switching to the new thermo stable formulation of epoprostenol sodium at the discretion of the investigator. Dose titration requirement will be assessed at the time of discharge. Haemodynamic parameters will be obtained in a subgroup of subjects enrolled in centres where the collection of haemodynamic data is considered part of the standard of care. Subjects will receive the study medication as a continuous intravenous infusion for a 4-week treatment period. Those who complete the 4-week treatment period will have the option of entering an extension phase of the study to continue receiving the new formulation.

Number of Participants With Abnormal HematologyUp to 1 week after Week 4 (Follow-up)Values for hemoglobin, hematocrit, and platelet count were analyzed. Participants with abnormal values have been reported. The low and high value concern were as follows: hemoglobin (Males \< 98, \>180.0) (females \<91, \>161.0)grams per litre (g/L); hematocrit (Males \< 32.0, \>54.0) (females \<29.0, \>50.6) fraction (1); platelet count (\< 100, \> 500) gram international units per litre (gI/L).
Number of Participants With Abnormal UrinalysisUp to 1 week after Week 4 (Follow-up)Dipstick method was used to measure blood, glucose and protein. Data was analyzed up to 1 week after Week 4 (Follow-up visit).
Number of Participants With Any Treatment Emergent Adverse Events (AEs) and Treatment Emergent Serious Adverse Events(SAEs)Up to visit 3 (Week 4)An AE was defined as any untoward medical occurrence that occurred during the course of the trial after study treatment had started. An adverse event was therefore any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. An SAE is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, congenital anomaly/birth defect and medically significant and all events of possible drug-induced liver injury with hyperbilirubinaemia. Only treatment emergent AEs and SAEs were reported in this outcome measure. Specifically, this study reported 2 SAEs, but only 1 was categorized as treatment emergent.
Breathlessness After 6MWD - Borg Dyspnoea Index (BDI)Baseline (Visit 2 i.e. Day-14 [+ or - 7 days]) to Week 4The BDI was calculated by using a 10-point scale (0 = None, 10 = Maximum) and indicates the degree of breathlessness after completion of the 6-minute walk test. The BDI scale was assessed by each participant. Change from Baseline = score at observation minus score at Baseline. Baseline visit was Visit 2 i.e. Day-14 (+ or - 7 days).
World Health Organization [WHO] Functional Class at Baseline and After 4- Weeks of TreatmentBaseline (Visit 2 i.e. Day-14 [+ or - 7 days]) and Week 4World Health Organization functional class was analyzed as class I, class II, class III and class IV.
