Alprostadil is a Small Molecule owned by Endo Pharmaceuticals, and is involved in 2 clinical trials, which were completed.

Alprostadil is a prostaglandin analog and prostaglandin E1 agonist. It is a potent vasodilator agent that increases peripheral blood flow, inhibits platelet aggregation, and induces bronchodilation. Alprostadil causes vasodilation by means of a direct effect on vascular and ductus arteriosus (DA) smooth muscle, preventing or reversing the functional closure of the DA that occurs shortly after birth. This is because, as a form of prostaglandinE1 (PGE1) it has multiple effects on blood flow. This results in increased pulmonary or systemic blood flow in infants. Alprostadil is administered as intracavernosal injection or as an intraurethral suppository in the treatment of erectile dysfunction. It produce corporal smooth muscle relaxation by binding to PGE receptors, resulting in the activation of adenylate cyclase and the subsequent accumulation of 3'5'-cAMP.

The revenue for Alprostadil is expected to reach a total of $354m through 2038. This change impacts the valuation of this asset and is an important factor to understand the current value of the drug in a clinical process. GlobalData uses proprietary data and analytics to provide a complete picture of this assessment in their Alprostadil NPV Report.

Alprostadil is currently owned by Endo Pharmaceuticals. Endo International is the other company associated in development or marketing of Alprostadil.

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

To create this model, GlobalData takes into account factors including patent law, known and projected regulatory approval processes, cash flows, drug margins and company expenses. Combining these data points with GlobalData’s world class analysis creates high value models that companies can use to help in evaluation processes for each drug or company.

The rNPV method integrates the probability of a drug reaching a clinical stage into the cash flow at that time, which provides a more accurate valuation, as it considers the probability that the drug never makes it through the clinical pathway to commercialization. GlobalData’s rNPV model uses proprietary likelihood of approval (LoA) and phase transition success rate (PTSR) data for the indication in the highest development stage, which can be found on GlobalData’s Pharmaceutical Intelligence Center.
