The revenue for Sepiapterin is expected to reach an annual total of $168 mn by 2034 in the US based off GlobalData’s Expiry Model. The drug’s revenue forecasts along with estimated costs are used to measure the value of an investment opportunity in that drug, otherwise known as net present value (NPV). Applying the drug’s phase transition success rate to remaining R&D costs and likelihood of approval (LoA) to sales related costs provides a risk-adjusted NPV model (rNPV). The rNPV model is a more conservative valuation measure that accounts for the risk of a drug in clinical development failing to progress.

Sepiapterin Overview

Sepiapterin (PTC-923 (CNSA-001)) is under development for the treatment of moderate to severe diabetic gastroparesis, tetrahydrobiopterin (BH4) deficiency resulting in hyperphenylalaninemia and phenylketonuria, segawa disease, central nervous system disorders and unspecified indications. The drug candidate is a tetrahydrobiopterin derivative. It is a small molecule administered through oral route. The drug candidate acts by targeting tetrahydrobiopterin.

it was also under development for the treatment of Parkinson's disease.

GlobalData

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.
