The fantasy: 'spray-on-skin' for leg ulcers... WTF?

A novel spray-on skin treatment consisting of living cells made by Smith & Nephew, which is designed to work with the body’s own cells to help heal leg ulcers, has failed in a late-stage clinical trial.
The product, known as HP802-247, was viewed by some analysts as a key pipeline asset in the company's advanced wound management division and the Phase III failure is a setback for the healthcare group, which is a regular subject of takeover talk.
The unsuccessful North American trial, announced on Monday, is also something of a surprise, given the promise of earlier studies.
