Study Endpoints

Primary Endpoints

Percent Change From 0 Hour in Pulmonary Vascular Resistance (PVR) at 0.5 Hour Post-separation From Cardiopulmonary Bypass (CPB)
0 hour, 0.5 hour post-separation from CPB

PVR in participants was derived from mean pulmonary artery pressure (PAP) (millimeter of mercury \[mmHg\]), pulmonary capillary wedge pressure (PCWP \[mmHg\]) and cardiac output (CO \[litres per minute\]). It was calculated using the following formula: (\[mean PAP-PCWP\] divided by CO)\*80, where CO= stroke volume (SV)\*heart rate (HR). Post-separation from CPB was the time immediately following cross-clamp release in CPB. Percent change in PVR at 0.5 hour post-separation from CPB in participants were summarized and reported.

Percent Change From 0 Hour in Pulmonary Vascular Resistance (PVR) at 6 Hour Post-separation From Cardiopulmonary Bypass (CPB)
0 hour, 6 hour post-separation from CPB

PVR in participants was derived from mean PAP (mmHg), PCWP (mmHg) and CO (litres per minute). It was calculated using the following formula: (\[mean PAP-PCWP\] divided by CO)\*80, where CO= SV \* HR. Percent change in PVR at 6 hour in participants were summarized and reported.

Percent Change From 0 Hour in Pulmonary Vascular Resistance (PVR) at 12 Hour Post-separation From Cardiopulmonary Bypass (CPB)
0 hour, 12 hour post-separation from CPB

PVR in participants was derived from mean PAP (mmHg), PCWP (mmHg) and CO (litres per minute). It was calculated using the following formula: (\[mean PAP-PCWP\] divided by CO)\*80, where CO= SV \* HR. Percent change in PVR at 12 hour in participants were summarized and reported.

Percent Change From 0 Hour in Pulmonary Vascular Resistance (PVR) at 24 Hour Post-separation From Cardiopulmonary Bypass (CPB)
0 hour, 24 hour post-separation from CPB

PVR in participants was derived from mean PAP (mmHg), PCWP (mmHg) and CO (litres per minute). It was calculated using the following formula: (\[mean PAP-PCWP\] divided by CO)\*80, where CO= SV \* HR. Percent change in PVR at 24 hour in participants were summarized and reported.

Mortality: Number of Participants Died During Surgery and Initial Hospitalization
During surgery, initial hospitalization period (up to 29 days for 1 mg/kg group, up to 44 days for 2 mg/kg dose group, up to 19 days for placebo group)

Number of participants who died during surgery or during initial hospitalization are reported here.

Number of Participants With Myocardial Infarction, Cerebrovascular Event, Hemodynamic Collapse and Re-operation
Initial hospitalization period (up to 44 days)

Number of participants with following incidents: myocardial infarction (Q and non-Q wave); stroke or cerebrovascular event (acute ischemia, hemorrhagic stroke or infarction, or a transient ischemia attack); hemodynamic collapse (requiring ventricular assistance devices) and re-operation (participants who returned to the operating room) during the initial hospitalization were reported.

Secondary Endpoints

Number of Participants With Inotropic Requirements During the 24 Hours Postoperative Period
Immediately after cross-clamp removal up to 24 hours post-separation from CPB
Change From 0 Hour in Cardiac Output (CO) at 0.5, 6, 12, and 24 Hours Post-Separation From Cardiopulmonary Bypass (CPB)
0, 0.5, 6, 12, 24 hours post-separation from CPB
Change From 0 Hour in Central Venous Pressure (CVP) at 0.5, 6, 12, and 24 Hours Post-separation From Cardiopulmonary Bypass (CPB)
0, 0.5, 6, 12, 24 hours post-separation from CPB

Frequently asked questions about sitaxsentan

What is sitaxsentan?

Sitaxsentan is a small molecule drug candidate that Pfizer, Inc. (ticker: PFE) has studied in the cardiovascular therapeutic area. It is also known as sitaxsentan (Thelin). The specific indication pursued in its clinical program is undisclosed, and the asset has reached Phase 2 testing.

Who makes sitaxsentan?

Sitaxsentan is developed by Pfizer, Inc., which trades under the ticker PFE. Pfizer sponsored the clinical work conducted on the compound, including the Phase 2 study run in the United States in patients undergoing heart surgery.

What phase is sitaxsentan in?

Sitaxsentan is in Phase 2 development. It is an investigational small molecule and is not described as approved. One Phase 2 trial has been completed, and no trials are currently active, so the program's recorded clinical activity consists of that finished study.

What clinical trials is sitaxsentan in?

Sitaxsentan has been studied in one completed Phase 2 trial, NCT00838383, titled Confirming The Sitaxsentan Dose In Patients Undergoing Heart Surgery. That randomized, placebo-controlled study enrolled 29 participants in the United States, including subjects undergoing CABG and/or cardiac valve replacement, with a minimum age of 48 years.

Is sitaxsentan the same as Thelin?

Yes. Sitaxsentan is also known as sitaxsentan (Thelin), so searches for Thelin refer to the same compound. It is a small molecule developed by Pfizer, Inc. (ticker: PFE) in the cardiovascular therapeutic area and has been tested at the Phase 2 stage.
