Disease

Names and IDs as Open Targets gives them. Its IDs in MeSH, Orphanet, the Disease Ontology and the NCI Thesaurus are those Open Targets states for it.

Name: Pulmonary arterial hypertension associated with portal hypertension; Open Targets
Open Targets ID: EFO_0009197; Open Targets
Other names: PAH associated with portal hypertension, POPH, Portopulmonary hypertension, portal hypertension-associated PAH; Open Targets
Orphanet: ORPHA:275813; Orphanet
Highest stage of its drugs: Phase 3, for 1 of its 3 drugs, from ClinicalTrials.gov; Open Targets

Drugs3

The drugs Open Targets' clinical reports study for the disease, the highest stage first, then the most trial reports. The stage is Open Targets', the highest any of its sources reports for the pair, and each row names the sources that report it.

Targets4

The targets ChEMBL's mechanism records give for the disease's drugs, through Open Targets, the most drugs first. A mechanism record says what a drug acts on, not that the target causes the disease.

EDNRA	Endothelin receptor, ET-A/ET-B	1	Endothelin receptor, ET-A/ET-B antagonist	Phase 3	https://conductscience.org/library/genes/1909	Drugs and targets

Trials4

Trials an Open Targets clinical report links to the disease, posted results first, then the largest. A trial is shown when the release's checks confirm its link to the disease and Drugs and targets shows its link to one of the disease's drugs.

NCT01224210	Ambrisentan in Patients With Porto-pulmonary Hypertension A Multicenter Open Label Trial	Phase 3	30	2021-01-12	Portopulmonary Hypertension	AMBRISENTAN	Its record names the disease	ClinicalTrials.gov

NCT00145938	Sildenafil and Pulmonary Artery Pressure	Phase 2	10		Pulmonary Hypertension	SILDENAFIL	Its record names the disease	ClinicalTrials.gov
NCT01733095	Ambrisentan for Treatment of Portopulmonary Hypertension	Phase 1/2	0		Portopulmonary Hypertension	AMBRISENTAN	Its record names the disease	ClinicalTrials.gov

Comparisons in its trials0

Comparisons Trial comparisons calculated in the trials shown here, most participants first. A comparison in one of these trials does not always compare a treatment for the disease, so read the two groups.

None in this release.

Papers from its trials1

The papers the trials shown here list on ClinicalTrials.gov as their results (RESULT) or as drawn from them (DERIVED), results first, newest first.
