Respironics field action

On June 14, 2021, Royal Philips’ subsidiary, Philips Respironics, initiated a voluntary recall notification* for certain sleep and respiratory care products to address identified potential health risks related to the polyester-based polyurethane (PE-PUR) sound abatement foam in these devices. Following the substantial ramp-up of its production, service, and repair capacity, the repair and replacement program in the U.S. and several other markets is under way. Philips Respironics has also been conducting a comprehensive test and research program on the PE-PUR foam to better assess and scope potential patient health risks related to possible emission of particulates from degraded foam and certain Volatile Organic Compounds (VOCs).

Resolution of personal injury and medical monitoring litigation in the US
Summary of settlement

Philips and plaintiffs’ leadership, through a Court-appointed mediator, have reached an agreement to resolve the personal injury litigation and the medical monitoring class action in the US

The personal injury settlement addresses the claims filed in US courts and potential claims submitted to the census registry

Philips and Philips Respironics do not admit fault, liability, or that any injuries were caused by the devices

It is the responsibility of plaintiffs’ leadership and the Settlement Administrator to allocate the funds to personal injury claimants they deem eligible. Philips is not endorsing any particular per-patient or per-injury amounts

Philips Respironics has agreed to pay capped total amount of USD 1.1 billion (covering all costs); most of the related payments are expected in 2025 and to be funded by cash on hand.

Plaintiffs’ leadership will not be pursuing any further claims in the Multidistrict Litigation (MDL), and the census registry has already been terminated

Regardless of whether eligible personal injury claimants filed a case, joined the census registry, or did nothing at all, they had until the extended deadline of January 31, 2025, to sign up for the settlement

Amount is capped regardless of number of participants

As required, 95% of individuals with qualifying injuries have agreed to participate in the personal injury settlement

For any individuals who still wish to continue to pursue litigation, they will first need to comply with a case management order (also known as Lone Pine Order), which requires them to come forward with prima facie injury, exposure and causation evidence, or else face dismissal

Philips and Plaintiffs’ leadership are confident that the vast majority of potential personal injury claimants have already identified themselves, given:

Recall was initiated almost four years ago, followed by extensive advertising

MDL formed more than three years ago

Census registry was active beginning in September 2022, and volumes were stable prior to its termination

To the extent any new personal injury claims surface, those individuals:

Will also be subject to the Lone Pine order

Will not have access to completed expert reports and will have to prepare their own experts reports

May already be time-barred

Medical Device Reporting

Medical Device Reporting

Medical device manufacturers are required to submit medical device reports (MDRs) to the FDA when they receive complaints for certain types of device malfunctions and safety issues

These complaints may be submitted to the manufacturer by health care professionals, patients, caregivers and consumers

The FDA acknowledges that “the submission of an MDR itself is not evidence that the device caused or contributed to the adverse outcome or event” and that the “cause of an event cannot typically be determined from this reporting system alone”

Following Philips’ public statements on possible risks to users in April 2021 and the June 2021 recall notification/field safety notice, Philips Respironics received a steep increase in complaints allegedly associated with possible foam degradation

This led to approximately 230,540 MDRs filed by Philips Respironics to the FDA from April 2021 through March 31, 2025

The vast majority of the MDRs filed since April 2021 up to and including March 2025 are alleged technical malfunctions that do not involve serious injury or death. Based on the investigations to date, Philips Respironics has found no conclusive data linking these devices and the deaths reported in the MDRs

Other legal matters

Other legal matters

Collective and individual civil complaints have been filed in various jurisdictions globally, including but not limited to the US, Australia, Canada, Israel and Chile. The complaints variously allege economic loss, personal injury, and in some cases, the need for medical monitoring

SoClean, a manufacturer of ozone-based CPAP cleaning devices, filed an amended complaint against Philips and certain of its US affiliates, including Philips Respironics, in October 2022 for alleged unfair competition, tortious interference with business relationships, defamation, and commercial disparagement

In January 2024, Philips countersued SoClean for marketing its ozone cleaners as compatible with Philips PAP devices without the required FDA approval or clearance, despite knowing that ozone can degrade PE-PUR foam. Allegations include false advertising, trademark dilution and deceptive trade practices

Philips has also filed a third-party complaint against SoClean seeking contribution to the personal injury settlement. That litigation is ongoing

Securities class action suit was filed against the company in August 2021 in the US, alleging Philips’ statements in connection with the recall triggered a fall in stock price. The company moved to dismiss the case, which the court granted in part, dismissing certain individuals from the case, dismissing certain claims, and narrowing the remaining claims. The company will vigorously contest the remaining claims, which it continues to believe are wholly unsupported, and intends to seek their dismissal as the case proceeds

In July 2024, Philips filed a lawsuit against PSN Labs seeking damages for the harm caused by the laboratory’s flawed assessment of potential health risks related to the PE-PUR sound abatement, as well as its subsequent cover-up of its mistakes.

On April 8, 2022, Philips Respironics and certain of Philips’ subsidiaries in the US received a subpoena from the DOJ to provide information related to events leading to the Philips Respironics recall. The relevant subsidiaries are cooperating with the agency

Following earlier requests for information from the US Securities and Exchange Commission (SEC), in March 2024, the company received a subpoena from the SEC relating to the Respironics recall and compliance with relevant securities laws. The investigation is not an indication that the SEC or its staff have determined that any violations of law have occurred. The company is fully cooperating with the investigation

Given the uncertain nature of the relevant events, and of their potential impact and associated obligations, if any, the company has not provided for these matters

Next steps

Next steps

Additional testing for sleep therapy devices to supplement current test data as agreed with the FDA¹

VOC and Particulate Matter testing, as well as chemical evaluation and toxicological assessments for Trilogy 100/200 (~3% of registered devices), and OmniLab (~2% of registered devices)

New Trilogy 100/200 devices passed VOC and PM testing to date, as well as several biocompatibility tests including ISO 10993 cytotoxicity, irritation and sensitization testing

New and lab-aged Trilogy 100/200 foam failed ISO 10993 genotoxicity testing under laboratory conditions, and therefore a weight of evidence assessment is ongoing to confirm or exclude potential risks for patients

These devices contain a different type of PE-PUR foam than the DreamStation1 devices²

1. Following ongoing communications with the FDA, Philips Respironics has agreed to implement additional testing to supplement current test data on PE-PUR foam. The FDA stated that current testing is extensive and conducted with independent parties and expressed no concerns with its validity or objectivity. Additional testing on the CPAP and BiPAP sleep therapy devices is ongoing in consultation with the FDA

2. The known differences between the DreamStation foam and the foam for the Trilogy 100/200, are that the latter can be used with an acrylic pressure sensitive adhesive, has a lower density, has a different thickness, and also contains an additive to reduce potential flammability

Summary of third-party epidemiological studies

Summary of third-party epidemiological studies

There were thirteen identified epidemiological studies, all of which found no consistent statistical association between use of PAP devices - including Philips Respironics’ - and the risk of cancer in patients with obstructive sleep apnea (OSA) - click here for more details

Two of the studies¹ showed no statistical difference in cancer risk between users of Philips Respironics PAPdevices and users of other brands of PAP devices

Eleven studies provided limited additional insights, but their results also suggested no excess risk of cancer associated with use of PAP devices

The 2022 study by Palm and others reported more frequent prescription of respiratory relief medication among patients with both OSA and obstructive lung disease, but no statistical difference in hospitalization, i.e., health outcomes, was observed for OLD among OSA patients between the users or polyurethane PAP and non-foamPAP - click here for more details
