Big Pharma, Big Data: Why Drugmakers Want Our Health Records

Real-world evidence is attracting a lot of attention, pro and con

Drug-makers are racing to scoop up patient health records and strike deals with technology companies as big data analytics start to unlock a trove of information about how medicines perform in the real world, according to a Reuters report.

Studying such real-world evidence (RWE) offers manufacturers a powerful tool to prove the value of their drugs—something Roche aims to leverage, for example, with last month’s $2 billion purchase of Flatiron Health.

RWE involves collecting data outside traditional randomized clinical trials. Half of the world’s 1,800 clinical studies involving RWE since 2006 have been started in the last three years, with a record 300 last year, according to a Reuters analysis of the National Institutes of Health’s website. Hot areas for such studies include cancer, heart disease and respiratory disorders.

Historically, it has been hard to get a handle on how drugs work in routine clinical practice, but the rise of electronic medical records, databases of insurance claims, fitness wearables, and even social media now offers a wealth of new data.

The ability to capture the experience of real-world patients, who represent a wider sample of society than the relatively narrow selection enrolled in traditional trials, is increasingly useful as medicine becomes more personalized. However, it also opens a new front in the debate about corporate access to personal data at a time when tech giants Apple, Amazon, and Google’s parent Alphabet are seeking to carve out a health care niche. Some campaigners and academics worry such data will be used primarily as a commercial tool by drug-makers and may intrude upon patients’ privacy.

Learning from the experience of millions of patients provides granularity and is especially important in a disease like cancer, where doctors want to know if there is a greater benefit from using a certain drug in patients with highly specific tumor characteristics. In the Flatiron deal, Roche is acquiring a firm working with 265 U.S. community cancer clinics and six major academic research centers, making it a leading curator of oncology evidence. Roche, which already owns 12.6% of Flatiron, will pay $1.9 billion for the rest.

All the world’s major drug companies now have departments focused on the use of RWE across multiple diseases, and several have completed studies using the information to delve into key areas addressed by their drugs. They include diabetes studies by AstraZeneca and Sanofi, joint research by Pfizer and Bristol-Myers Squibb into stroke prevention, and a Takeda Pharmaceutical project in bowel disease.

“It’s getting more expensive to do traditional clinical trial research, so industry is looking at ways it can achieve similar goals using routinely collected data,” said Paul Taylor, a health informatics expert at University College London.

FDA Commissioner Scott Gottlieb believes more widespread use of RWE could cut drug development costs and help doctors make better medical choices. Under the 21st Century Cures Act, the FDA has been directed to evaluate the expanded use of RWE. “As the breadth and reliability of RWE increases, so do opportunities for FDA to also make use of this information,” Gottlieb said in a speech last September.

But the growth of real-world evidence also raises questions about data access and patient privacy. Sam Smith, a campaigner for medical data privacy at Britain’s MedConfidential, is concerned drug-makers’ RWE studies are just a cover for marketing. “How much of this is really for scientific discovery and how much is it about boosting profits by getting one product used instead of another?”

Some academics also worry RWE studies could be susceptible to “data dredging,” where multiple analyses are conducted until one gives the hoped-for result.

AstraZeneca’s head of innovative medicines Mene Pangalos, whose company has struck several deals with tech start-ups and patient groups to gather real-world data, acknowledges ensuring privacy and scientific rigor is a challenge. “It’s a real problem but I don’t think it’s insurmountable,” he told Reuters. “As people get more comfortable with real-world evidence studies I think it will be much more widely used. I would like to see a world where real-world data can be used to help change drug labels and be used much more aggressively than it is today.”

Roche Chief Executive Severin Schwan believes data is the next frontier for drug-makers, and he is betting that the Swiss group’s leadership in both cancer medicine and diagnostics will put it in pole position. “There’s an opportunity for us to have a strategic advantage by bringing together diagnostics and pharma with data management. This triangle is almost impossible for anybody else to copy,” he said.

Still, even Roche cannot work alone in this new world. “You can have a big debate about whose data it is—the patient‘s, the government‘s, the insurer’s—but one thing for sure is the pharmaceutical company does not own it. So there’s no choice but to do partnerships,” Schwan said.
