Onapristone ER is a Small Molecule owned by Context Therapeutics, and is involved in 14 clinical trials, of which 8 were completed, 5 are ongoing, and 1 is planned.

Onapristone ER (IVV-1001) is an anti-progestin and anti-hormone. Anti-progestin is substance that prevents cells from making or using progesterone. It works by competitively binding to the progesterone receptor, resulting in inhibition of the effects of endogenous or exogenous progesterone. Antiprogestin inhibits the growth of different cancer cell lines with a cytostatic effect in association with a decline in the activity of the cell cycle regulatory protein Cdk2, and apoptotic lethality. Onapristone ER appears to have a unique ability to block the activated progesterone receptor, which is believed to be the mechanism by which it may inhibit the growth of breast and endometrial tumors.

The revenue for Onapristone ER is expected to reach a total of $1.9bn 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. View the complete picture with the Onapristone ER NPV Report.

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, potential applicable patients, drug margins, company expenses, and pricing estimates. 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 rNPV, 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.
