For decades, the United States has led the world in pharmaceutical innovation — developing drugs that combat cancer, heart disease, AIDS, diabetes and other killer diseases. One recent study found that “in health-sciences output in the Nature Index, the United States’ Share is almost 8,500, higher than the next 10 leading countries combined.”

The industry’s research and development has saved and improved tens of millions of lives in the U.S. alone. Yet somehow Washington has come to regard the industry as a villain.

The newest U.S. wonder drug — Zepbound — is extraordinarily effective in driving major weight loss. This drug is now being used by millions of people and contributing to an improvement in the country’s health. Users of the drug treatments, which suppress appetite, typically lose 10%-20% of their body weight after taking the shots. This miracle drug is reducing lives lost from obesity, heart disease, cancer and stress.

Here’s the problem: The cost of developing new drugs and getting them approved typically exceeds $2 billion — and takes 10-15 years — according to the Tufts Center for the Study of Drug Development.

For every drug approved by the Food and Drug Administration, there are nearly a dozen that fail and lose money for investors. The rare wonder drug “hits” have to pay off to cover the cost of the much more common dead-end research — the “misses.”

The future of American drug innovation is threatened by U.S. regulations that permit knockoff versions of new drugs to be sold to U.S. consumers. Today, companies known as “compounders” specialize in creating these knockoffs — and cashing in along the way. They generated nearly $5 billion in revenues in 2023.

Compounders freeload off the high R&D costs and slow approval times associated with developing new drugs. Instead, they modify patented, FDA-approved medicines by adding an additional ingredient or tinkering with the doses and then mass-produce knockoffs. But there is no science supporting this trickery in the case of the weight-loss drugs.

The weight-loss drugs were so successful that demand outstripped supply. The FDA determined there was a shortage of Ozempic and Wegovy and allowed the copycat drugs access to the market.

But there is no shortage today. The FDA moved those weight-loss drugs off their shortage list but gave compounding pharmacies an extra 60-90 days to stop producing their drugs.

This was an undeserved gift that rewards the knockoffs to the tune of millions of dollars while penalizing the companies that did the hard and expensive work of creating these drugs and getting them approved.

The FDA should cut off access to these fake and unsafe drugs and allow the normal patent process to work to protect our intellectual property. Patent protection is what has made America the leading disease combatant of the world and what will speed along the next generation of lifesaving drugs.
