Molecular Diagnostics Are in a Rut. The Industry Needs the FDA

Some of the more exciting ideas in biotech are coming up in molecular diagnostics. There’s cool science at work. A number of tests have potential to cut down on overtreatment, reduce waste in healthcare, and give physicians clever new ideas on how to help patients.

But this industry, which accounts for less than 2 percent of healthcare spending, is stuck in neutral. If it’s ever going to grow into a bigger business that delivers lots of valuable information about health, the molecular diagnostics industry needs a tough, science-minded, credible regulator. It needs a thorough, predictable, and efficient third party who can comb through complex data sets and say with confidence what’s real, what’s clinically meaningful, and what’s BS.

Physicians, patients, and payers aren’t just going to do this by themselves.

Just like the pharmaceutical industry, the diagnostics world needs a strong FDA.

“We have to have some kind of pathway that gets rid of the uncertainty hanging over the whole space now,” says Kim Popovits, CEO of Redwood City, CA-based Genomic Health (NASDAQ: [[ticker:GHDX]]), a leader in molecular diagnostics.

While the FDA has done some things in recent years to improve how it reviews companion diagnostics that help guide treatments for cancer, there is still a vast swath of the diagnostics world that is lightly regulated at best. It allows for skepticism about these tests to fester among payers, and spawns fear among investors who worry the payers will never pay. “We’d like a process that has clarity and some certainty around how you do it,” Popovits says. “When you develop a drug, you go through Phase I, II, and III, and then you go to FDA. They say ‘yea or nay,’ and then you get reimbursed. That’s a process we need.”

For sure, the idea of tough, consistent FDA regulation of diagnostics isn’t new. The FDA has been making noises for years about getting more aggressive about regulating “high-risk” laboratory-developed tests (LDTs) that influence big healthcare decisions like how to treat a cancer patient—where the consequences of a false test can be dire. AdvaMed, the trade group for medical device and diagnostic companies, has said the FDA should regulate “higher-risk” tests. Industry leaders Brook Byers of Kleiner Perkins Caufield & Byers and Mara Aspinall of Roche’s Ventana Medical Systems unit co-wrote an op-ed for the Boston Globe in 2011 about why they think the FDA should bring more rigorous regulation to the diagnostics business.

“For one thing, both payers and physicians need and deserve to have confidence that the advanced diagnostic methods being used are reliable and accurate,” Byers and Aspinall wrote. “As it stands today, diagnostics are regulated by a variety of state and federal agencies, but there are, as yet, no clear policies in place for the approval of new molecular diagnostics.”

Not a whole lot has changed on the regulatory front in the last couple years, but a lot has changed in the technology world. Consider some recent diagnostics stories:

—Cambridge, MA-based Foundation Medicine (NASDAQ: [[ticker:FMI]]) introduced a test in 2012 that takes a tumor sample from a cancer patient and scans it for alterations in 235 cancer-related genes to see what might be driving the tumor. Like many other lab-based companies, Foundation Medicine’s lab is certified under the usual Clinical Laboratory Improvement Amendments (CLIA) standard—a pretty low bar. The company has published its analytical methods in a top peer-reviewed journal, going further than most of its peers. But the Foundation Medicine test is not approved by the FDA for providing a clinically validated, health-outcome altering diagnostic test. Medicare still hasn’t come out with a consistent policy saying what the test is worth. The result? Foundation Medicine has to fight tooth and nail, and negotiate with payers, to get reimbursed each time a patient gets its test.

The company, to its credit, acknowledges the barrier to entry is pretty low, and it’s willing to jump over higher regulatory hurdles. “The stakes are high. You have really ill patients. There are doctors without a lot of bandwidth to reconcile conflicting results. We have to be right in what we report out to oncologists and pathologists,” says Vince Miller, chief medical officer of Foundation Medicine. “As we continue in this era of precision medicine, the good news is that the value of molecular diagnostics in cancer should go up. We’re certainly prepared and hopeful that the barriers to entry and new standards will be raised as well.”

—South San Francisco-based Crescendo Bioscience just enjoyed a big success, being acquired by Myriad Genetics (NASDAQ: [[ticker:MYGN]]) for $270 million. Crescendo, another lightly regulated CLIA lab, developed a proprietary test that looks at 12 proteins in a blood sample of patients with rheumatoid arthritis. It’s the first-ever quantifiable way of measuring the molecular activity of this common inflammatory disease. It’s a radical new idea in a world where physicians—even in 2014!—basically just squeeze knuckle joints, ask patients how much it hurts, and then make a subjective judgment on what to do next. The Crescendo test has the potential to tell a physician when a cheap generic drug is holding the disease in check at the molecular level, or when a $20,000 a year biotech drug isn’t getting the job done. Without going through an FDA clearance process, Crescendo had a pretty easy path to the market. But it took Crescendo three years on the market before it could get Medicare reimbursement at $575 per test. After a decade of work and $100 million in venture capital, the company got to the point
