In its rush for the next breakthrough, the field of psychiatry often discards older, effective treatments due to historical stigma. For instance, MAO inhibitors and modern, safer Electroconvulsive Therapy (ECT) are highly effective for specific depression types but are underutilized because of past negative associations, a phenomenon driven more by politics than science.

When a promising ALS drug failed Phase 2 trials, the company shut down. The drug's original founder, Dr. Ari Azhir, still believed in the science, repurchased the asset and all its data, and ultimately uncovered its true potential, leading to a new FDA application.

Breakthrough drugs aren't always driven by novel biological targets. Major successes like Humira or GLP-1s often succeeded through a superior modality (a humanized antibody) or a contrarian bet on a market (obesity). This shows that business and technical execution can be more critical than being the first to discover a biological mechanism.

The transition to an engineering discipline in drug discovery, analogous to aeronautics, means using powerful in silico models to get much closer to a final product before physical testing. This reduces reliance on iterative, expensive, and time-consuming wet lab experiments.

To build investor confidence in the high-risk neuroscience field, Neurocrine employs a dual strategy. It highlights its own proven track record while simultaneously de-risking its pipeline by targeting biological pathways already validated by competitors, aiming to create superior, best-in-class medicines rather than pursuing unproven science.

Progress in drug development often hides inside failures. A therapy that fails in one clinical trial can provide critical scientific learnings. One company leveraged insights from a failed study to redesign a subsequent trial, which was successful and led to the drug's approval.

The GSK3 inhibitor was developed for CNS diseases, requiring high specificity and the ability to cross the blood-brain barrier. These same pharmaceutical characteristics—potency and lipophilicity—proved highly advantageous for treating cancer, demonstrating an unexpected but effective therapeutic pivot from neuroscience to oncology.

Biotech companies create more value by focusing on de-risking molecules for clinical success, not engineering them from scratch. Specialized platforms can create molecules faster and more reliably, allowing developers to focus their core competency on advancing de-risked assets through the pipeline.

Neurocrine's strategy with its M4 agonist hinges on achieving superior safety and tolerability through high selectivity. The company believes that for chronic psychiatric disorders, long-term patient adherence—driven by fewer side effects—is a more critical factor for commercial success than marginal gains in efficacy.
