CDRH Looks to Drugs for Inspiration

CDRH Looks to Drugs for Inspiration

By Jim Dickinson 

When FDA’s current regulatory scheme for medical devices was being invented on Capitol Hill in the 1976 Medical Device Amendments, the universal credo was “don’t emulate drug regulation—medical devices are not drugs.”

So a totally different, less prescriptive matrix came into being, the most striking feature of which was section 510(k), under which new medical devices could enter the market without any FDA action at all, simply on the manufacturer’s notification of intent and sufficient documentation to show “substantial equivalence” to an already marketed, and thus grandfathered, pre-1976 device. FDA could disagree for good reason and prevent marketing, but the new matrix assumed this would be a rarity.

Like any new invention, the new regulatory scheme had its teething troubles. Adjusting interpretations were made in the courts and in Congress over the ensuing years, and there were numerous and typically unconfessed administrative abuses.

But always the 1976 Amendments’ defenders kept up the conceptual mantra: “Devices are not drugs.” Whenever CDRH was asked to look over the wall to its sister Center for Drug Evaluation and Research (CDER) for ideas, a negative chorus arose.

Until now. In what some may see as a tacit admission that “regulation lite” has not been a runaway success, FDA commissioner Margaret Hamburg openly acknowledged before a March hearing of the Senate Health, Education, Labor, and Pensions Committee that CDRH is now looking at approval pathways CDER provides to pharmaceutical companies as a means to build new mechanisms to help speed devices to market.

CDRH, Hamburg said, can learn from CDER and “real-world use with postmarket surveillance and collection of data and additional postapproval studies” that could speed devices that meet an unmet medical need to market.

“That has been a theme of the drug side, and it is part of CDRH’s strategic plan as an approach to integrating postmarket studies into the overall assessment and an ongoing understanding,” she said. “We will be eager to work with stakeholders to shape this pathway as we go forward.”

Relying on postmarketing data to speed device approvals is part of CDRH’s proposed Innovation Pathway, a program intended to put pioneering medical devices on the fast-track to review.

“We put out our Innovation Pathway as a way for engaging with the innovators far earlier in the device development in a shared, collaborative way for us to better understand newer technology,” CDRH director Jeffrey Shuren told a recent industry conference.

“When we don’t have a regulatory pathway in place, then let’s try to figure out that pathway together,” he urged. “What we did with the artificial pancreas is a nice example, and you will see more of that coming out in the future... Another innovative move is to also look at the circumstances where we might be able to shift some of the established premarket data needs into the postmarket setting, either through a more formal data collection process or by leveraging the national medical device surveillance system as we start to get that off the ground.”

A draft guidance is planned and CDRH is looking to obtain more stakeholder input on the proposal.

Newly appointed CDRH associate director for technology and innovation Murray Sheldon told a separate conference that the initial approach to implementing the new pathway involves practicing new review concepts without dismantling CDRH’s core review procedures, including the 510(k), IDE and Premarket Application (PMA).

If proven successful, Sheldon said, new review concepts applied to the more innovative products will be expanded to other existing review programs. He noted that experimentation is now underway with innovative reviews of three products intended to treat end-stage renal disease, chosen from among 32 device applicants.

Other Innovation Pathway projects for 2014 include study of ways to streamline clinical trials, ways to streamline approval to reimbursement (in collaboration with Medicare and CMS), and striking the “right” balance between pre- and postmarket evidentiary requirements.

According to Sheldon, an essential aspect of the Innovation Pathway will be to create a “shared view” of what constitutes program—and product—success. He indicated that reviewers must begin to understand the time-cost of different regulatory choices and work with sponsors to create a more collaborative environment.

The use of FDA’s IT Conference Center, which allows conference participants—sponsors and CDRH staff—to meet via Skype for exchange of views, will help foster and maintain “forward momentum” on innovative projects as they move through the development process.

Intuitive Stock Surges 13% As It Readies New Surgical Robot

Intuitive Surgical has announced FDA clearance and the U.S. launch of its new da Vinci Xi Surgical System. The company, in a Tuesday news release, described the Xi as a "technological leap forward in replacing large-incision abdominal surgeries (open surgery) with a minimally invasive approach." The company plans to market the da Vinci Xi System around the world. News of U.S. approval of its latest robotic-assisted minimally invasive surgery system caused Intuitive's stock to rise nearly 13% in value, to nearly $494 per share, at the close of trading Tuesday. It's now up more than 28% year-to-date. "The da Vinci Xi System's new overhead architecture means that multi-quadrant surgery can be performed without repositioning the system, an innovation long sought by surgeons who perform complex procedures," Gary Guthart, Intuitive Surgical's president and CEO, said in a news release. Intuitive needs the boost, because Guthart and other executives in the company have been engaged in damage control in the discourse regarding the safety of Da Vinci robotic surgery. Guthart has complained that despite reported adverse events and ongoing FDA issues, surgery with the Da Vinci system is still far safer than conventional open surgery. Medgadget is also reporting on new competition for Intuitive Surgical from SOFAR, an Italian pharmaceutical firm, that has its own surgical robotics platform: "The Telelap ALF-X features haptic feedback, allowing the surgeon to indirectly 'feel' the tissues that are being manipulated. This can lead to improved safety and allow certain maneuvers to be performed with greater confidence."

When it comes to its stock price, Intuitive Surgical is one of the best performing medical device companies of early 2014. But it is also worth noting that it was trading at more than $500 a share a year ago. The da Vinci Xi System expands upon core da Vinci System features, including wristed instruments, 3D-HD visualization, intuitive motion, and an ergonomic design. Improvements upon older models include a new overhead instrument arm architecture designed to facilitate access to a patient from virtually any position; a new endoscope digital architecture that creates a simpler, more compact design; an ability to attach the endoscope to any arm, improving visualization; and smaller, thinner arms with newly designed joints to improve range of motion.

Thoratec LVAD Recall Gets Class I Status

The FDA on Tuesday issued a Class I recall designation over Thoratec's advisory involving four patient deaths related to its HeartMate II left ventricular assist device (LVAD).

HeartMate II
HeartMate II, as shown on Thoratec's website
The issue actually has nothing to do with the LVAD itself, but rather is related to patients and caregivers who were unable to understand instructions and lacked the training needed to hook up a back-up system controller in cases of device alarm or malfunction. Besides resulting in four deaths, such difficulties also caused lost consciousness or reduced blood flow for five other patients, according to Pleasanton, CA-based Thoratec and the FDA. The FDA elaborates on what happened:
"All reports were linked to patients whose HeartMate II LVAS device was originally attached to an older model of controller, the EPC System controller. When the Pocket System Controller became available, patients were switched from the EPC System Controller to the Pocket System Controller. However, these patients did not receive intensive training on connecting the new controller."

Thoratec sent an "Urgent Medical Device Correction" letter by email to all affected customers in early March. The company is updating labeling and training materials for the HeartMate II LVAS Pocket System Controller and has been urging physicians, caregivers and patients to get up to speed on the new instructions and training. Thoratec isn't the only company experiencing potentially deadly issues around device instructions. The FDA has also been warning that a Greatbatch Medical Orthopedic surgical tool could cause serious injury or death because it came with inadequate sterilization recommendations.

CoreValve Beats Traditional Valve Replacement in Trial

Medtronic has announced the results of two studies testing its CoreValve transcatheter aortic valve replacement product, which were presented at the American College of Cardiology's 63rd Annual Scientific Session in Washington, DC.

The High Risk Study of the CoreValve US Pivotal Trial met its primary endpoint with a low one-year, all-cause mortality rate of only 14.2 percent in patients receiving the CoreValve System, compared to 19.1 percent in patients receiving surgical aortic valve replacement (SAVR). "We're making continual progress. It's not only an alternative but may be a preferable alternative [to open heart surgery]," said David Adams, MD, a co-principal investigator in the study in an interview with Reuters.

Final four-year follow-up results from the CoreValve CE Pivotal Study, which demonstrated excellent long-term durability in patients with severe aortic stenosis who were treated with the CoreValve System, were also announced.

The CoreValve High Risk Study, simultaneously published in The New England Journal of Medicine, showed that the CoreValve System is superior to SAVR in patients with severe aortic stenosis who are considered high risk for surgery.

Medtronic says this is the first and only study to show the superiority of a transcatheter aortic valve over conventional surgery. Its CoreValve System met its primary study endpoint with higher than expected survival. All-cause mortality at one year was only 14.2% in patients receiving the CoreValve System, versus 19.1% in patients receiving SAVR. This difference calculates to be a 26% decrease in mortality risk.

Major stroke rates in patients who received the CoreValve System were 3.9% at 30 days and 5.8% at one year, versus 3.1% at 30 days and 7.0% at one year for patients who received SAVR. Medtronic says these stroke rates were low and not statistically different. This finding is said to be important because stroke is one of the complications most concerning to physicians and patients because it increases mortality and affects quality of life.
