Without antibiotics, many of us would be dead already, and modern medicine would not exist.
Now, most antibiotics are redundant because of the spread of antibiotic resistance around the world.
By 2050, it is predicted that more people will die from resistant microbes, than will die from cancer and diabetes combined.
The most dangerous of these resistant bacteria are CRE* (see video ).
For the past forty years no new classes of antibiotic against CRE have been marketed.
Helperby Therapeutics is one of a small handful of companies which has a treatment for CRE at the clinical trials stage of development.
