Our take
Clinical drug trials are lengthy and expensive, delaying the supply of vital new drugs to patients and costing lives. For Formation Bio, this is an efficiency issue - one which it hopes to solve with its end-to-end automation solution.
According to the company, its approach has teams running medical trials twice as fast and at half the cost. This success has pushed Formation to expand beyond supporting trials into developing assets itself. In 2025, it reached a major milestone by licensing its first drug in a deal worth up to hundreds of millions. Alongside this, the company has also added an early immunology program to its pipeline, signalling a broader push into in-house development.
Now a Unicorn, with partners including Pfizer, Sanofi, Novartis and 23andMe, Formation Bio is steadily embedding itself within the Big Pharma ecosystem. How far it can go remains an open question, but the prospect of cheaper drugs and faster innovation is becoming harder for the industry to ignore.
