Maybe not enough of it is absorbed into the blood stream. Maybe the drug is not specific to the target, and binds to other molecules in undesirable ways. The hit-to-lead process involves selecting the most promising hits, testing them, and modifying to make them more "drug like". They are just starting points for future drug development efforts. I use the term "matter" rather than "drugs" because the compounds used in these screens often don't have the qualities needed to be a drug: they may be toxic, they may not get to the right place within the body, etc. Hits are molecules that interact with the target in the desired way. The target-to-hit process entails screening large libraries of chemical or biologic matter to find "hits". Researchers select targets that they believe are highly involved in causing disease or making disease worse. The "active case" changes when you change the assumptions below the "base case" represents the original assumptions.įor a more detailed overview of the drug development process, see this post.Ī target is a molecule that the drug is intended to interact with. Later in this post, there's a tool that lets you play around with the assumptions driving this valuation model. The chart also shows the total investment required to reach each stage, and the probability that a drug reaches a given stage. The inputs are cost and time of development, probability of success at various stages of the drug development process, market size, costs of commercialization, and discount rate.
The below chart shows the output of the drug valuation calculator: how the value of a drug program grows over time, assuming the program is successful at each stage (if it fails, the value generally goes to zero). The post is accompanied by two tools that can help you apply this knowledge: an interactive drug valuation calculator and an excel spreadsheet with an example of how a drug company might be valued. I'll describe key concepts related to risk and value in biotech, provide some examples of how risk and valuation drive company strategy, and examine whether current biotech valuations are in-line with fundamentals. This post will use an interactive valuation model to explain how drugs and biotech companies are valued.
