Baxter Obtains U.S. FDA Emergency Use Authorization for Oxiris Blood Purification Filter for COVID-19 Treatment

Press Release
  • Only filter set available in the U.S. to reduce pro-inflammatory cytokine levels in the blood, including use in continuous renal replacement therapy (CRRT), for confirmed COVID-19 cases admitted to the ICU with confirmed or imminent respiratory failure who require blood purification

  • Support from U.S. Food and Drug Administration (FDA) enabled accelerated authorization process

  • Validated for use with Baxter's leading blood purification systems, PrisMax and Prismaflex

  • Supplements Baxter's efforts to increase supply of acute dialysis products that are in high demand

Oxiris Prismaflex Set



Baxter International Inc. (NYSE:BAX), a global leader in acute care, announced it has received emergency use authorization (EUA) from the U.S. FDA for the company's Oxiris filter set to treat patients who have confirmed COVID-19 and have been admitted to the intensive care unit (ICU) with confirmed or imminent respiratory failure in need of blood purification therapy to reduce pro-inflammatory cytokine levels, including use in continuous renal replacement therapy (CRRT).  

"We are doing whatever it takes to support healthcare providers as they care for patients during extraordinary circumstances. Oxiris offers a new tool in the COVID-19 fight while supplementing our overall supply of filters for blood purification therapies," said José (Joe) E. Almeida, chairman and chief executive officer.  "We are grateful for the FDA’s collaboration and support to make Oxiris available as quickly as possible to the influx of patients who are critically ill from COVID-19."

In severe cases of COVID-19, patients may develop acute kidney injury (AKI), a condition where the kidneys suddenly stop working, and/or cytokine storms, which occur when high levels of the inflammatory mediators circulate in the blood as an intense immune reaction to the virus. Both conditions can be life-threatening and require intervention. Early studies suggest that 15 to 30% of patients with severe forms of COVID-19 are developing AKI,while 67% of severely ill patients with COVID-19 infection may present with additional organ dysfunction syndromes that could be induced by a high level of circulating cytokines.2  

During blood purification therapy, the patient's blood passes through the Oxiris filter set, where it then removes cytokines, endotoxin, fluid and uremic toxins simultaneously, before returning the patient's blood to the body. Oxiris is the only filter set available in the U.S. that can be used to perform multiple blood purification therapies simultaneously, including CRRT and cytokine removal. When Oxiris is used, there is no change to traditional CRRT set up and delivery and no additional equipment is required for removal of inflammatory mediators. Unlike other products, Oxiris does not require the use of a second CRRT filter or adsorber, which can help conserve resources. 

Oxiris is currently in use across countries in Europe and Asia and has been used for more than 10 years to treat thousands of patients. Oxiris has been validated for use with Baxter's leading PrisMax and Prismaflex systems. PrisMax, which was launched in the U.S. in 2019, is the company's next-generation blood purification platform that helps simplify therapy delivery, while providing hospitals the flexibility to meet the unique demands of the ICU. 

A small initial shipment of Oxiris will be available in the U.S. immediately, with more significant production ramping up throughout the coming weeks and months.

Increasing Product Supply & Distribution to Respond to COVID-19

Baxter is maximizing production of its CRRT machines, fluids and sets to help address unprecedented surges in demand for its acute dialysis products in Europe and the U.S. The company has added multiple work shifts, with all facilities manufacturing products used in COVID-19 patient care running 24 hours a day, seven days a week. The company is partnering with vendors on a component-by-component basis to procure additional raw materials and parts to support increased production. In addition, Baxter has partnered with its logistics providers to fly critically needed medical devices and medicines back and forth between the U.S. and Europe. Flights started this past weekend, and the company expects the equivalent of one cargo plane per day will be transporting products for the next three weeks. This will accelerate the availability of products for patient care over the second quarter. Read more about our response here.

2. Severe disease, defined as:

  • Dyspnea,
  • Respiratory frequency ≥ 30/min,
  • Blood oxygen saturation ≤ 93%,
  • Partial pressure of arterial oxygen to fraction of inspired oxygen ratio < 300,and/or
  • Lung infiltrates >50% within 24 to 48 hours

3. Life-threatening disease, defined as:

  • Respiratory failure,
  • Septic shock, and/or
  • Multiple organ dysfunction or failure
