Clinical trials

What it is

Clinical trials are the staged human studies that decide whether a treatment works and is safe enough to approve: small phase 1 safety studies, mid-size phase 2 dose and signal studies, and large randomised phase 3 trials that regulators rely on. Most drugs that enter trials fail, and a positive early-phase press release is not evidence of benefit. Stories tagged here include trial results, recruitment and diversity problems, regulatory speed, and the growing move of trials to Africa and Asia.
