Primary Outcome Measures:
  • Change From Baseline in 6-minutes Walk Test (6MWT) at Week 12 [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]
    The 6MWT measures the distance that a participant can walk in a period of 6 minutes. Change from Baseline was calculated as the Week 12 value minus the Baseline value. Baseline 6MWT comprised of an average of the last two consecutive measurements prior to dosing that varied by not greater than 10 percent (%). If only one measurement was available, that measurement was used as the Baseline value. The last observation carried forward method was used to impute missing values.


Secondary Outcome Measures:
  • Change From Baseline in 6MWT at Week 24 [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
    The 6MWT measures the distance that a participant can walk in a period of 6 minutes. Change from Baseline was calculated as the Week 24 value minus the Baseline value. Baseline 6MWT comprised of an average of the last two consecutive measurements prior to dosing that varied by not greater than 10%. If only one measurement was available, that measurement was used as the Baseline value. The last observation carried forward method was used to impute missing values.

  • Number of Participants With a Change From Baseline in Their World Health Organization (WHO) Functional Classification (FC) at Weeks 12 and 24 [ Time Frame: Baseline, Week 12 and Week 24 ] [ Designated as safety issue: No ]
    The WHO FC was determined by the investigator as follows: Class I- Participants with pulmonary hypertension (PH) but without resulting limitation of physical activity, II- Participants with PH resulting in slight limitation of physical activity, III- Participants with PH resulting in marked limitation of physical activity, IV- Participants with PH with inability to carry out any physical activity without symptoms. Changes from Baseline in functional class were summarized at Weeks 12 and 24. The number of participants improving by 2 classes, improving by 1 class, not changing, worsening by 1 class or worsening by 2 classes from Baseline at Weeks 12 and 24 were evaluated. The Baseline value was the last non-missing assessment value before treatment. Only participants with non-missing Baseline values and at least one non-missing post-Baseline value of the response variable were included. The last observation carried forward method was used to impute missing values.

  • Change From Baseline in the Borg Dyspnea Index (BDI) at Weeks 12 and 24 [ Time Frame: Baseline, Week 12 and Week 24 ] [ Designated as safety issue: No ]
    The BDI was calculated by using a 10-point scale (0 = None, 10 = Maximum). Change from Baseline was calculated as the Week 12 and 24 values minus the Baseline values. The BDI indicates the degree of exertion, breathlessness, fatigue, or difficulty breathing after completion of the 6MWT. The lower values, 0 as the lowest, indicates no exertion, fatigue, or breathlessness felt, and 10 would be the maximum amount of exertion felt as assessed by each participant. The last observation carried forward method was used to impute missing values.

    N-Terminal Pro-B-Type Natriuretic Peptide (NT-proBNP) is a surrogate maker of heart failure and was measured by a central laboratory. Mean change from Baseline at Weeks 12 and 24 were calculated as the Weeks 12 and 24 values minus the Baseline values.Observed data was analyzed (no imputation technique was performed for missing data). Log transformed mean change from Baseline at Weeks 12 and 24 data are summarized.

    Time to clinical worsening is defined as the time from Baseline to the first occurrence of death, lung transplantation, hospitalization for PAH treatment, atrial septostomy, or Investigational product (IP) discontinuation (discon) due to change to other PAH treatment. Time to clinical worsening was measured as the number of participants who experienced these events during 12 and 24 Weeks.

    An adverse event (AE) is defined as any untoward medical occurrence in a participant temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. A serious adverse event (SAE) is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, a congenital anomaly/birth defect, or important medical events that jeopardize the participants or may require medical or surgical intervention to prevent one of the other outcomes listed in the above definition.

The physical examination included an examination of the following: general appearance, skin, head, ears, eyes, nose, throat, neck, thyroid, lymph nodes, cardiovascular system, respiratory system, abdomen, musculoskeletal system, neurological system and height. Physical examination summary results were not collected therefore there is no data to present for this outcome measure.

Detailed Description:

Pulmonary arterial hypertension (PAH) consists of a group of progressive and incurable diseases of the pulmonary vasculature. These are characterised by profound vasoconstriction and abnormal proliferation of smooth muscle cells in the walls of the pulmonary arteries, which leads to a progressive increase in pulmonary vascular resistance (PVR) and sustained elevations in pulmonary artery pressure (PAP). A variety of drug classes have been used to treat PAH but no single compound has yet been shown to be effective in treating all patients with the disease. Three widely used treatment options are calcium channel blockers (CCBs), diuretics and anticoagulants but all have varying responses.There is a lack of clinical data on ambrisentan among the Chinese population,Ambrisentan is conditionally approved for the treatment of PAH in China.A clinical trial with a minimum of 100 patients in the ambrisentan arm was requested by SFDA.Several PAH medications have been approved in China, so a placebo-controlled study is not ethically appropriate while an active control non-inferiority design is unfeasible due to sample size requirements and inconsistency in indications.
