Friso Postma, vice president of AI for drug discovery at BioXcel Therapeutics, prefers the term “augmented intelligence” to “artificial intelligence.” His company uses AI tools to support human experts in drug repurposing efforts.

Postma, who holds a Ph.D. in signal transduction from the Netherlands Cancer Institute, transitioned to AI from wearable digital health devices. “I quickly found out that it’s very important to be able to contextualize AI,” he explains.

Now, Postma, trained as a biologist and electrophysiologist, that experience in contextualizing AI has been instrumental in developing and continuously refining an end-to-end platform for drug re-innovation, focusing on neurological rare and psychiatric disorders. This platform, which he helped create, is now central to his ongoing work. “Interestingly, I’m not a data scientist or an AI engineer, …

Repurposing is a drug development strategy that has been widely applied in cancer. This strategy, sometimes called label expansion, involves obtaining FDA approval to market a drug for the treatment of new indications, alone or in combination with other drugs. Not only can this approach extend the window of patent protection for a commercialized drug, but the path to regulatory approval can also be far less costly and risky than the traditional approach to drug development, largely because clinical evidence of safety already exists. And most importantly, the result is more and better treatment options for patients.

In keeping the law of unintended consequences, recent provisions introduced by the 2022 Inflation Reduction Act (IRA) blunted the potential benefits of drug repurposing. As a result of limiting the window of time during which pharmaceutical companies can recoup investments before…
