Elucent Medical wins FDA nod for EnVisio breast surgery navigation device

Elucent Medical

Elucent Medical said today that it won FDA 510(k) clearance for its EnVisio surgical navigation system.

The Eden Prairie, Minn.-based company said that the EnVisio navigation system is designed for use in conjunction with the company’s SmartClip soft tissue marker during breast cancer procedures.

The SmartClip soft tissue marker is an alternative to hook-wire localization procedures used to identify malignant tissue for removal, the company said. When used with the Envisio system allows physicians to mark difficult lesions and navigate distances, depths and directions in real-time 3D during breast cancer procedures.

“Elucent Medical is offering a cost-effective solution that addresses a key challenge for breast surgeons: how to easily find the location of a malignant biopsy during surgery, especially in tissue that lacks anatomical landmarks. We developed a system designed by surgeons to be intuitive, efficient, and precise, eliminating the need for a localization procedure. We believe this innovation has the potential to improve cosmetic and clinical outcomes, with other possible applications for lymph and thoracic surgeries,” co-founder Dr. Lee Wilke said in a press release.

“Our vision is to disrupt the standard of care for women who receive localization prior to their lumpectomy as part of their breast cancer treatment. Today we take a significant step toward achieving this goal. The EnVisio Navigation System and SmartClip Soft Tissue Markers will provide patients and surgeons with a wire-free, minimally invasive alternative for pre-surgical planning and navigation throughout surgery,” co-founder and CEO Laura King said in a prepared statement.

Australia’s TGA considering, but not yet implementing, textured breast implant ban

Australia's TGA

Australia’s TGA said yesterday that it is seeking new data from suppliers of textured breast implants, which have been linked to a rare immune-system cancer, before making a decision on whether or not to suspend or cancel those products from its Register of Therapeutic Goods.

The regulatory body gave suppliers of the devices 10 working days to respond to the requests for more information, including dates they began to supply the devices and samples of the implants, according to a TGA release.

The decision comes after the convening of a breast implant expert panel on April 8, following recent decisions made in Canada and France to remove select implants from the market.

The implants have been linked to breast implant-associated anapestic large cell lymphoma (BIA-ALCL), a type of non-Hodgkin’s lymphoma.

The TGA said that the panel it convened discussed current data on the implants associated with BIA-ALCL and identified gap in the data that affected estimation of the true rate of the cancer in the country.

The regulatory body said that as of April 8, it has received 76 reports of BIA-ALCL in Australian women. The agency said that there are approximately 13,000 to 17,000 breast implant procedures performed in the country each year.

The panel also discussed the benefits of textured implants, particularly for reconstructive new surgery, and made suggestions including a need to update the TGA’s website with risks and benefits and to better encourage use of the Australian Breast Device Registry.

The TGA said that like the FDA and many other regulatory bodies, it has been monitoring BIA-ALCL cases since 2011, adding that the first adverse event report it received related to the cancer came in in 2009.

The agency said that textured implants of varying roughness are used in 82% of operations in the country.

Last month, a panel of experts convened by the FDA said that there’s not enough data to pull textured breast implants from the market over concerns that they may be linked to a type of immune system cancer.

FDA wants to update mammography standards

The FDA today issued a proposed rule that would modernize mammography quality standards and require mammography facilities to provide more information to patients and healthcare providers.

The proposed rule would be the first update in 20 years, amending regulations issued under the Mammography Quality Standards Act of 1992, which authorizes FDA oversight over mammography facilities, including their accreditation, certification, annual inspections and enforcement of standards. The new proposal could help patients and providers make more informed decisions regarding care, and boost the FDA’s regulatory power over the safety and quality of mammography services, the agency said.

The proposed amendments include:

  • Adding specific language about breast density to the mammography results summary letter provided to patients and to the medical report sent to providers.  Mammograms of breasts with a higher proportion of dense fibroglandular tissue compared to fatty tissue can be difficult to interpret because the dense tissue can obscure signs of breast cancer, lower the sensitivity of the image and increase the risk of developing breast cancer.
  • Codifying three more categories for mammogram assessment, including one titled “known biopsy-proven malignancy,” which would help identify for health care professionals cases in which cancer that is being evaluated by mammography for therapy has already been identified.
  • Adding more detailed information about the mammography facility to patient summaries and medical reports for caregivers to aid in post-exam communications.

Proposed changes to boost the FDA’s enforcement powers include:

  • Expressly stating that the FDA can directly notify patients and their health care professionals, should facilities be unwilling or unable to do so, that mammography at a facility did not meet quality standards and that reevaluation or repeat of the mammogram at another certified facility may be needed.
  • Requiring facilities to use only FDA-approved or -cleared digital accessory components for mammography, or that facilities use components that otherwise meet the requirements under the rule.
  • Strengthening record-keeping requirements to minimize information loss and improve access to and transfer of patient mammography records.

“As part of our overall commitment to protecting the health of women, we’re proposing new policies to modernize our oversight of mammography services, by capitalizing on a number of important advances in mammography, like the increased use of 3-D digital screening tools and the need for more uniform breast density reporting,” said FDA commissioner Dr. Scott Gottlieb in a prepared statement. “We’re committed to making sure patients have access to high-quality mammography. Today’s proposed rule would help to ensure patients continue to benefit from advances in new tools and robust oversight of this field.”

According to the National Cancer Institute (NCI), approximately 12.4% of women will be diagnosed with breast cancer at some point during their lifetime. NCI estimates that, in 2018, more than 260,000 women were diagnosed with breast cancer and more than 40,920 women died of the disease. Aside from skin cancer, breast cancer is the most common cancer among women and the second leading cause of death. Mammography can also be an important tool in detecting male breast cancers. According to the NCI, breast cancer may occur in men at any age, but usually occurs in men between 60-70 years of age.

“The FDA is committed to advancing efforts that improve the health of women,” said FDA principal deputy commissioner Dr. Amy Abernethy. “Given that more than half of women over the age of 40 in the U.S. have dense breasts, helping to ensure patient access to information about the impact that breast density and other factors can have on the risk for developing breast cancer is an important part of a comprehensive breast health strategy.”

The proposed rule may be found here and is available for public comment for 90 days from publication.

FDA Panel: Too early to pull textured breast implants over cancer risk, need more data

FDA

A panel of experts convened by the FDA yesterday said that there’s not enough data to pull textured breast implants from the market over concerns that they may be linked to a type of immune system cancer, according to an AP News report.

The recommendation comes from the first day of a two-day panel meeting discussing the risks associated with breast implant devices, reviewing current study data and exploring how to best track and treat the cancer, and other issues, the devices have been tied to.

The FDA only began reporting on the cancer, known as breast implant-associated anaplastic large cell lymphoma, and its link to implants in 2011. Last month, the federal watchdog said it has received 457 unique reports of the cancer, with 246 new adverse event reports related to it since 2017.

Estimates of the frequency of the disease range greatly, from one in 3,000 to one in 30,000, according to the AP News report. The disease has also been reported to the FDA by patients with smooth implants, and other research has indicated that silicone that leaks from the implant could possibly trigger or exacerbate immune system disorders.

Despite the increased visibility of the cancer and its link to implants, the panel did not recommend any immediate restrictions on the devices, according to the report. The majority of the 19 panelists said that it was too soon to pull the products from the shelves.

Consumer advocates, and the panel’s consumer representative, did not agree, according to AP News. The consumer rep said that many women who receive the implants do so as part of reconstructive surgery following breast cancer surgery, and the risk of subjecting those women to a second cancer was enough to justify their commercial removal.

Panelists were receptive to patient advocates’ calls for more standardized risk disclosures and informed consent for women considering the devices, according to the report.

The panel is meeting again today, continuing to explore how to diagnose and treat the breast implant-linked cancer as well as other concerns related to the devices.

Though they are meeting for another day, the panel is still not expected to recommend a ban on textured implants, according to SVBLeerink analyst Richard Newitter, which is good news for manufacturers of the devices, including Sientra(NSDQ:SIEN) and Johnson & Johnson (NYSE:JNJ) subsidiary Mentor Worldwide.

Both Sientra and Mentor received warning letters last week from the FDA over failures to conduct appropriate post-approval studies of the devices.

“It seems more likely that the panel will focus its “actionable” recommendations on: (a) improved data collection around implants going into patients (at the time of primary & revision surgeries,) (b) stepped up infrastructure/resources to facilitate (possible mandatory) registry participation, (c) more compliant post-surgery surveillance on the part of industry, and (d) a more rigorous approach to informed consent,” Leerink analyst Newitter said in a letter to investors.

The FDA said today it has begun more closely scrutinizing the roles of certain materials associated with harm to patients who have breast implants, nitinol-containing devices, metal-on-metal hip implants and devices made from animal-derived substances.

It’s the latest in a series of statements the agency has issued following increasingly harsh public criticism of its efforts to regulate the medical device industry. In the past year, Netflix’s documentary “The Bleeding Edge” and the International Consortium of Investigative Journalists’ “The Implant Files” series ripped the agency and the industry over patient injuries attributed to faulty devices. The FDA has been particularly faulted for its 510(k) clearance pathway, under which it allows devices that are similar to previously approved technology to undergo a less strenuous review before they can be sold.
