To counter the inevitable patent expiration of its blockbuster drug Jakafi, Incyte's long-term strategy involved developing superior internal products to replace it. This approach aims to cannibalize its own revenue stream before competitors can.

The company once invested 13% of revenue in R&D but saw stagnant growth. The issue was that new products were primarily replacing older ones, not creating new markets. This improved profitability but highlighted the need to balance R&D between incremental improvements and true market expansion.

Since most biotech programs fail (as few as 1 in 10 succeed), a company's survival depends on running a portfolio of multiple programs simultaneously. This requires the discipline to quickly terminate unsuccessful projects and the foresight to have subsequent programs already underway.

A promising drug can be rendered obsolete if a competitor develops a superior, disease-modifying therapy that eliminates the original market need. This highlights that competitive dynamics are as critical as scientific validity, as when a cystic fibrosis therapy was sidelined by Vertex's core treatment.

Gilead consistently demonstrates an appetite for high-risk, novel science. From pioneering CAR-T (Kite) and new ADCs (Trodelvi) to its latest T-cell engager deal, the company's acquisition history signals a clear preference for cutting-edge platforms rather than safer, later-in-class assets.

Gilead has tightened its criteria for advancing projects, demanding a deep mechanistic understanding before committing significant resources. This involves validating the target, understanding its biological impact preclinically, and identifying biomarkers—moving beyond just a promising hypothesis to a de-risked scientific thesis.

To compete with China's rapid 'me-better' development, U.S. innovators should proactively partner with Chinese firms to create improved versions of their own drugs. This self-cannibalization strategy is necessary to stay ahead before competitors do it for them.

While biotech cannot easily replicate tech's rapid iteration cycles due to high costs and long feedback loops, it can adopt the capital efficiency model of tech seed investing. The strategy is to kill flawed projects quickly and cheaply, ensuring that when you lose, you lose small.

Gilead timed its acquisition of Arcelix to capitalize on peak investor sentiment and a surging stock price, which were driven by its successful HIV franchise. This allowed the company to strategically bolster its smaller oncology pipeline from a position of financial and market strength.
