Area Under the Plasma Concentration-time Curve From Time Zero to Last Time of Quantifiable Concentration [AUC(0-t)] After Administration of AMB Under Fasted Condition
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 18, 24, 36, 48 and 72 hours post-dose

Blood samples were collected at indicated time-points for PK analysis of AMB. PK parameters were calculated by standard non-compartmental analysis.

Apparent Terminal Phase Half-life (t1/2) After Administration of AMB Under Fasted Condition
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 18, 24, 36, 48 and 72 hours post-dose

Blood samples were collected at indicated time-points for PK analysis of AMB. PK parameters were calculated by standard non-compartmental analysis.

Frequently asked questions about AMB new formulation

What is AMB new formulation used for?

AMB new formulation is an investigational small molecule being developed for pulmonary hypertension, a condition of high blood pressure in the arteries of the lungs. It is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

Who makes AMB new formulation?

AMB new formulation is being developed by GSK plc, a global biopharmaceutical company listed on the stock exchange under the ticker GSK. The company is conducting clinical trials to evaluate the drug's safety and pharmacokinetics in healthy volunteers.

What phase is AMB new formulation in?

AMB new formulation is in Phase 1 clinical development. A Phase 1 study has been completed, which evaluated the relative bioavailability of marketed and lower dose ambrisentan in healthy adult participants. The drug remains investigational and is not yet approved for any use.

What clinical trials is AMB new formulation in?

AMB new formulation has one completed clinical trial, NCT04095286, titled 'Relative Bioavailability Study of Marketed and Lower Dose Ambrisentan in Healthy Adult Participants.' This Phase 1 study enrolled 29 participants in the United Kingdom and was a controlled, randomized trial.

Is AMB new formulation the same as ambrisentan?

AMB new formulation is a new formulation of ambrisentan, a drug used for pulmonary hypertension. The clinical trial NCT04095286 compares the relative bioavailability of the marketed form and a lower dose formulation of ambrisentan, indicating that AMB new formulation is a modified version of the existing drug.
