The rise of drug-resistant bacteria is a growing threat to modern
medicine with the emergence of infections resistant to even
last-resort antibiotics - a situation made worse in recent years by
overuse of antibiotics and cutbacks in drug research.
New analysis by the non-profit Access to Medicine Foundation (AMF),
published on Tuesday, found that GlaxoSmithKline and Johnson &
Johnson were doing more than most among large research-based
pharmaceutical companies to tackle the problem, while Mylan led the
way among generic drugmakers and Entasis was top among biotechs.
Overall, GSK led the field with 55 antimicrobial pipeline projects,
including 13 vaccines.
But action taken by such companies is only the start of what could
be done to address the problem, which former Goldman Sachs chief
economist Jim O'Neill in 2014 estimated could cause 10 million
deaths a year worldwide by 2050.
"The whole of modern medicine depends on being able to control and
treat infections," said Jeremy Farrar, director of the Wellcome
Trust charity. "Perhaps the most exciting area of medicine at the
moment, immunotherapies for cancer, is impossible unless you can
control infection."
While more experimental antibiotics are now moving through
development than a few years ago, the number is still down on the
1980s and 1990s. And a lot more work needs to be done to ensure
appropriate use of medicines - both new ones and the thousands of
tonnes of older pills churned out each year by generic companies.
"There's definitely more that all companies can do," said Jayasree
Iyer, executive director of AMF, which published the analysis at the
World Economic Forum annual meeting in Davos.

"We need to strengthen the research and development pipeline - and
when new products reach the market we need to ensure that they are
used in a conservative way, so that misuse and overuse is limited."
There are now 28 experimental antibiotics in late-stage development
against critical pathogens but only two of these are supported by
plans to ensure they can be both made accessible and used wisely if
they reach the market.
The AMF said four companies - GSK, Shionogi, Pfizer and Novartis -
had taken steps to separate sales representatives' bonuses from the
volume of antibiotics sold, but much more needed to be done across
the industry to counter overuse.
Another under-recognized problem is the pollution caused by mass
production of antibiotics, due to lax oversight of wastewater
run-off.
In India's Hyderabad region, for example, the presence of hundreds
of drug factories and inadequate water treatment has left lakes and
rivers laced with antibiotics, making the area a giant Petri dish
for anti-microbial resistance.
The AMF urged multinational drugmakers to do more to ensure that
their suppliers of bulk antibiotic ingredients were complying with
rigorous wastewater standards.
