If India is among the countries hit hardest by "antimicrobial resistance," some hope is said to be on the horizon. According to a BBC report, "a number of promising locally-developed new drugs show potential to combat antibiotic-resistant pathogens. They also offer a game-changing solution to preserve last-resort treatments."
Antimicrobial resistance, according to the World Health Organisation (WHO) occurs when bacteria, viruses, fungi and parasites change over time and no longer respond to medicines making infections harder to treat and increasing the risk of disease spread, severe illness and death. As a result, the medicines become ineffective and infections persist in the body, increasing the risk of spread to others.
According to the BBC report, "Enmetazobactam, developed by Chennai-based Orchid Pharma, is the first antimicrobial invented in India to be approved by the US Food and Drug Administration (FDA)."
This injectable drug, the report adds, treats severe conditions like urinary tract infections (UTIs), pneumonia and bloodstream infections by targeting bacteria’s defence mechanisms rather than the bacteria itself.
Trials across 19 countries - the drug has been approved by global regulators - with more than 1,000 patients have shown its effectiveness. “The drug has shown remarkable potency against these bacteria that have evolved over the years. It is administered via intravenous [IV] infusion in hospitals, specifically for critically ill patients, and is not available over the counter,” Dr Maneesh Paul, the lead co-inventor of the drug was quoted as saying to the BBC.
Similarly, Mumbai-based Wockhardt is testing a new antibiotic, called Zaynich, for severe drug-resistant infections. Developed over 25 years, the drug is currently in Phase-3 trials and expected to launch next year.
Also in Phase-3 testing is Wockhardt's Nafithromycin, trademarked as MIQNAF, a three-day oral treatment for community-acquired bacterial pneumonia with a 97% success rate.
Among other things, the BBC report says that a 30-member Bengaluru-based biopharma firm Bugworks Research has partnered with Geneva-based non-profit Global Antibiotic Research and Development Partnership, or GARDP, to develop a new class of antibiotics for treating serious drug-resistant infections. Currently in early Phase-1 trials, the drug is five-to-eight years from market readiness.
