Lack Of New Antibiotics Threatens Global Efforts To Contain Drug-resistant Infections: WHO

UNITED NATIONS, (UrduPoint / Pakistan Point News - 18th Jan, 2020 ) :The World Health Organization, a U.N. agency has issued a fresh warning about the global threat of drug resistant infections which are on the rise as private investment in new antibiotic development declines.
Some 700,000 people die each year because medicines that once cured their conditions are no long effective. Yet the vast majority of the 60 new antimicrobial products in development worldwide are variations on existing therapies, and only a handful target the most dangerous drug-resistant infections, the agency said in a report.
"We urgently need research and development," said Sarah Paulin, technical officer of Antimicrobial Resistance and Innovation at the W.H.O. and an author of two reports on the subject issued Friday.
"We still have a window of opportunity but we need to ensure there is investment now so we don't run out of options for future generations." Without government intervention, the United Nations estimates that resistant infections could kill 10 million people annually by 2050 and prompt an economic slowdown to rival the global financial crisis of 2008.
In the two reports one that analyzed products being tested on patients and another that looked at therapies in the early stages of development the W.H.O. cited the grim economic realities that have been shutting down investment in the field by major pharmaceutical companies and strangling the few remaining small companies that have come to dominate development of antimicrobial therapies.
Unlike drugs that treat chronic conditions and are taken for years, antibiotics save lives, but are taken for just a week or two, diminishing their profitability for drugmakers.
"Never has the threat of antimicrobial resistance been more immediate and the need for solutions more urgent", WHO Director-General Tedros Adhanom Ghebreyesus said The reports also found that antibiotics research and development is primarily driven by small or medium-sized enterprises, as large pharmaceutical companies continue to exit the field.
"Numerous initiatives are underway to reduce resistance, but we also need countries and the pharmaceutical industry to step up and contribute with sustainable funding and innovative new medicines." With the aim of encouraging the medical research community to develop treatments for resistant bacteria, in 2017, WHO published a list of 12 classes of bacteria plus tuberculosis, that were resistant to most existing treatments and, thus, increasingly jeopardize human health.
Of the antibiotic agents in the pipeline, only a precious few target the rapidly spreading, multi-drug resistant Gram-negative bacteria.
Gram-negative bacteria, such as E-coli, can cause severe and often deadly infections that particularly threaten people with weak or not-yet-fully-developed immune systems, including newborns, the elderly, and people undergoing cancer treatment.
"It's important to focus public and private investment on the development of treatments that are effective against the highly resistant bacteria because we are running out of options", says Hanan Balkhy, WHO Assistant Director-General for Antimicrobial Resistance. "And we need to ensure that once we have these new treatments, they will be available to all who need them." The pre-clinical pipeline shows more innovation and diversity, with 252 agents under development to treat WHO-priority pathogens.
However, these products are in the very early stages and still need to be proven safe and effective. Forecasts suggest the first two to five products will not become available for another 10 years, said the report.
On a more positive note, the pipeline for antibacterial agents to treat tuberculosis and Clostridium difficile, which causes diarrhoea, is more promising, saying that more than half of the treatments fulfil all WHO-defined innovation criteria.
However, WHO says it has made clear that new treatments alone will not be sufficient to combat the threat of antimicrobial resistance and its scientists are working with countries and partners to improve infection prevention and control.
With the goal of delivering five new treatments by 2025, WHO and the Drugs for Neglected Diseases Initiative have established a non-profit research and development organization called the Global Antibiotic Research and Development Partnership, to develop new and improved antibiotics that tackle drug-resistant infections, the agency said.
The enterprise is currently working with more than 50 public and private sector partners in 20 countries to develop and ensure sustainable access to treatments.
