The Marketplace for New Antibiotics is Fundamentally Broken

One of the mysteries of COVID-19 is why it kills some patients while sparing others with similar health profiles.

The answer to this will not prove singular, of course. But research published in the prestigious medical journal The Lancet found that 50% of hospitalized patients who died of COVID-19 also had secondary bacterial infections. Some patients contracted these fatal infections from the very intensive care unit (ICU) ventilators that were intended to save them.

By contrast, just 1% of hospitalized COVID-19 survivors suffered from secondary infections.

Too often, the secondary bacterial infections that exploit those who are already ill are resistant to our existing arsenal of antibiotics. These “superbugs” — the result of antimicrobial resistance, or AMR — are a mounting threat to everyone. As a United Nations panel reported last year, “drug-resistant diseases already cause at least 700,000 deaths globally a year.” Unless we develop new and more potent antibiotics, that figure could increase to 10 million a year worldwide by 2050.

Scientists are well aware of this future dystopia — and have been ringing alarm bells for decades.

When antibiotics first became widely available in the 1940s, they revolutionized medicine by offering a way to cure deadly infections. But in the seven decades since — thanks in large part to overuse and misuse — some bacteria have evolved into new, drug-resistant strains. In short, what doesn’t kill bacteria makes them stronger.

Most recently, the small biotech firm Melinta Therapeutics – which has four antibiotics on the market – filed for bankruptcy. Another promising antibiotics company – Achaogen – also went bankrupt despite having successfully received FDA approval for a novel antibiotic against superbugs.

Fixing this broken incentive structure for new antibiotics is best achieved in two ways.

First, policymakers must address how the newest and most clinically appropriate antibiotics are paid for when used in a hospital. Today’s reimbursement rates effectively penalize physicians and hospitals for prescribing newer, more advanced antibiotics.

Second, government and other stakeholders should consider creative incentives — like “market entry rewards” — to risk-taking scientists and investors that successfully deliver novel antibiotics to patients.

Along these lines, more than 20 global biopharmaceutical companies just announced a $1 billion “AMR Action Fund,” that will directly invest in early-stage research efforts. The new fund will provide a vital lifeline to smaller biotech companies by offering the financial resources needed to take potential medicines from the innovation stage over the finish line.
That will prove a critical bridge to rectifying the fundamentally broken antibiotic market.

It’s time to get serious about developing new medicines to fight superbugs and uniting behind long-term fixes to the commercial market failure. Otherwise, the coming scourge of superbugs will prove just as — if not more destructive — than the COVID-19 pandemic.
