Recent Operating Highlights

  • Cumulative CytoSorb® treatments delivered exceeded 228,000 at the end of 2023, up 17% from the end of 2022
  • The 140-patient, double-blinded, multicenter, pivotal STAR-T randomized, controlled trial was selected for a Breakout Presentation at the American Association of Thoracic Surgery (AATS) Annual Meeting being held April 27-30, 2024 in Toronto, Canada. We expect to follow this event with an Analyst and Investor Day and provide a review of the data by an esteemed thought leader panel
  • We plan to submit for regulatory approval of DrugSorb®-ATR to the FDA and Health Canada in the second half of 2024 to reduce the severity of bleeding in patients undergoing isolated coronary artery bypass graft (CABG) surgery on the blood thinner, Brilinta®. This follows the prior discussion of topline study results in December 2023, and subsequent additional data analysis from the STAR-T Trial
  • Our European Union CE Mark for CytoSorb was extended under the Medical Devices Directive (MDD) to the earlier of either December 2028 or when we achieve E.U. Medical Device Regulation (MDR) certification, which effort is currently ongoing
  • Entered into a new strategic partnership and temporary distribution agreement in India for CytoSorb with the publicly-traded Indian pharmaceutical company, Eris Lifesciences, following its definitive agreement with Biocon Biologics to acquire Biocon’s Nephrology branded formulations business unit, and with it, Biocon’s key leadership and field force of these businesses, including the personnel commercializing CytoSorb in India
  • Expecting to launch our new PuriFi stand-alone hemoperfusion pump later this year following the expiration of our previously disclosed distribution agreement with Nikkiso Europe GmbH for its PureAdjust® hemoperfusion pump in September 2023

Dr. Phillip Chan, Chief Executive Officer of CytoSorbents stated, “In 2024, we are intent on providing clarity to investors on the key factors that will determine the near-term and future success of this Company. These include visibility on submission of DrugSorb-ATR for regulatory approval to U.S. FDA and Health Canada this year, returning to significant growth in our core existing CytoSorb business outside the U.S. and Canada, continued improvements in product gross margins coupled with a right-sized operating expense structure, and adequately financing CytoSorbents for success.”

STAR-T Update

The pivotal, U.S. and Canadian STAR-T (Safe and Timely Antithrombotic Removal – Ticagrelor) randomized controlled trial was designed to support FDA and Health Canada marketing approval for DrugSorb®-ATR to reduce the risk of perioperative bleeding in patients undergoing cardiothoracic surgery potentially caused by Brilinta® (ticagrelor, AstraZeneca). Our technology has received FDA Breakthrough Device Designation for this application, highlighting the major unmet medical need and lack of approved or cleared therapies for this problem.

Following the completion of the STAR-T trial last year, we announced topline data from the study in December 2023 as follows:

  • The independent STAR-T Data and Safety Monitoring Board (DSMB) conducted a review of unblinded data on all 140 patients in the trial and concluded there were no issues with device safety, meeting the primary safety endpoint of the study
  • Following initial data analysis from STAR-T, the primary effectiveness endpoint in the overall patient population that underwent different types of cardiac surgeries was not met. However, in the pre-specified subpopulation of patients undergoing isolated coronary artery bypass graft (CABG) surgery that accounted for more than 90% of patients enrolled in the STAR-T trial and also represent the main use case for DrugSorb®-ATR, we observed evidence of reduced bleeding complications, including serious bleeding events.

We have since performed additional analyses of our trial data in the isolated CABG population and believe the results further support the favorable benefit-to-risk profile of DrugSorb-ATR in these patients who represent the overwhelming majority facing this clinical unmet need.  

We are pleased at the selection of the STAR-T trial for a breakout presentation at the 104th Annual Meeting of the American Association of Thoracic Surgery, described as the world’s most prestigious cardiothoracic surgery event. This year, the meeting will be in collaboration with the Society of Cardiovascular Anesthesiologists (SCA), who are often managing blood product usage due to intraoperative bleeding during surgical procedures.   In general, this conference is targeted towards cardiothoracic surgeons and physicians in related specialties; perfusionists; non-physician health care providers involved in the care of cardiothoracic surgical patients; as well as fellows, residents, and medical students in cardiothoracic surgery. These are the stakeholders who directly witness and need to manage the perioperative bleeding complications of their patients on blood thinners and who would use DrugSorb-ATR in clinical practice.

Shortly after AATS, we plan to host an Analyst and Investor Day to share these data with participants, who will then be able to evaluate the benefit-risk proposition of DrugSorb-ATR.   Our data give us confidence in our decision to submit for regulatory approval to U.S. FDA and Health Canada, estimated in the second-half of 2024. For an interesting discussion on therapies seeking FDA approval in our situation, see page 3 of this report from Zacks Research.

Although we cannot predict the outcome of a regulatory submission, should DrugSorb-ATR be approved in both the U.S. and Canada only for patients undergoing isolated CABG, we believe the initial total addressable market opportunity remains relatively intact at approximately $325 million initially, and may expand significantly as ticagrelor (aka   Brilinta®, AstraZeneca) becomes generic this year and potentially displaces generic clopidogrel (aka Plavix®, BMS/Sanofi) in the market as the preferred P2Y12 inhibitor in patients with acute coronary syndromes based on both the superior efficacy data over clopidogrel and the ability to be removed in cases where urgent CABG is required (due to DrugSorb-ATR).

2023 Sales Highlights

2023 was a reasonable recovery year of progress and growth, where core (non-COVID-19) CytoSorb sales grew roughly 10% over the prior year. This was particularly true coming off of a challenging 2022 that we described last year as a “perfect storm” of geopolitical, economic, post-pandemic, and company-specific factors. That said, the results understate some of the excellent progress we are making to grow and diversify our revenue base, based upon our long-term growth strategy and investment commitments to support our hybrid sales model.

  • Strong performance from our International Direct sales division (representing 14 countries, excluding Germany) resulted in 27% sales growth year-over-year to approximately $6.0 million, or 19% of 2023 product sales
  • Distributor and Partner sales (representing more than 60 countries) grew 18% (excluding U.S. dsitributor sales in 2022) in the first three quarters of 2023 over the prior year. Based on our stand-alone pump initiative that is expected to catalyze sales of CytoSorb in countries with less developed dialysis capabilities, we had budgeted higher growth in Q4 for this division. For a number of different reasons, it became clear that Nikkiso’s PureAdjust® hemoperfusion machine was not the long-term solution for our stand-alone pump initiative and we mutually agreed to not renew our distributor agreement in September 2023.   We pivoted to an alternative strategy, focused on the launch of our own hemoperfusion machine called Purifi that we expect to launch later this year. Anticipation of this machine, however, led to some order slippage from distributors to the new year, resulting in lower than expected Q4 2023 sales overall. For the year, Distributor and Partner sales grew 9% (excluding U.S. distributor sales in 2022) to $12.1 million, or 39% of 2023 product sales
  • Direct Sales Germany was flat at 3% growth to $13.0 million for the year, or 42% of 2023 product sales. German hospitals are still working through the aftermath of the COVID-19 pandemic with staff shortages, decreased hospital beds, fewer patients, and fewer revenue generating procedures, and economic stressors such as inflation, labor, energy, and other unexpected costs.   Notwithstanding this market backdrop, the costs and challenges that physicians and healthcare workers continue to face in the management of critical illness and cardiac surgery are real. Given the numerous applications, both old and new, that our products can help to address, and other initiatives such as our preferred supplier agreement with the largest private hospital networks in Germany, we believe there are many opportunities to return to significant growth in the country.

That said, we are currently tracking a proposal for healthcare reform of Germany’s hospital system. In July 2023, Germany’s federal and state governments issued a consensus white paper that could result in new laws that change how hospitals are funded. Government payments to hospitals would de-emphasize the DRG (diagnosis-related group) “lump sum” payment system that incentivizes revenue generation through more patients treated and procedures performed, and instead emphasize base payments focused on quality measures and appropriate patient care.  This is expected to favor a shift of routine operations and procedures to outpatient centers, consolidation of smaller hospitals into larger ones, and importantly, an increased focus of remaining hospitals on sicker patients, more complex operations such as cardiothoracic surgery and organ transplant, and on therapies that help reduce the severity of illness and help patients recover faster.  Given that the goal of our therapies is to improve clinical outcomes while reducing the costs of critical care and cardiac surgery by controlling deadly inflammation and other life-threatening conditions, while reducing the need for expensive life support measures that keep patients in the hospital, we believe such reform may favor our business in the longer-term. Hospital administrators expect such change will take careful planning and time, potentially years, to implement. We continue to track these developments with interest.    

As we discussed in the last earnings release, we believe we can return to and potentially even exceed our historic compound annual growth rate (CAGR) of approximately 25%. We outlined a number of macro trends in healthcare that favor our therapies, such as the aging population that is prone to critical illness, the use of blood thinners by millions of people worldwide to reduce the risk of stroke and heart attack, and the epidemic of chronic liver disease that afflicts one in every five people globally.   Meanwhile, we also discussed our numerous growth initiatives, like our stand-alone pump intiative with the pending launch of our own PuriFi machine, the impact that supportive data from STAR-T may have on the blood thinner opportunity worldwide, our global marketing agreement with Fresenius Medical Care where CytoSorb is the featured solution for cytokine, bilirubin, and myoglobin removal on its critical care platforms worldwide, our new E.U. trademark of “Expanding the Dimension of Blood Purification®” that highlights the up to 40-50% of patients in the ICU where our therapies could be beneficial, and relatively “new” applications with exciting recently published clinical data in fields such as artificial liver support, fluid balance in septic shock, infective endocarditis, heart transplant, ex vivo organ perfusion – particularly lung transplant, acute respiratory distress syndrome (ARDS), and the effect of CytoSorb on gram negative endotoxin-induced cytokine storm – a major cause of septic shock.

Reduced Cash Burn with Tight Control Over Expenses

Following our equity financing in December, we ended the year with $15.6 million in cash, including $1.5 million in restricted cash, and $5 million in debt. We have implemented significant cost cutting measures to significantly reduce our cash burn, including a 15% reduction-in-force, termination of non-core R&D programs, termination of the STAR-D trial to focus on STAR-T, and a third consecutive year of salary freezes for executive management. The benefit of these cost cuts on operating expenses, particularly our headcount reductions, will become more apparent with time as notice periods and severance payments are completed. Finally, we have worked diligently to optimize our manufacturing efficiencies and expect CytoSorb product gross margins to be in the 75-80% range on a quarterly basis this year, after averaging 72% in 2023.

Dr. Chan concluded, “We believe the successful execution of our strategy will form the basis of a strong turnaround of our business and position us well for strong growth and profitability in the next several years. We thank you for your continued support.”

Results of Operations

Comparison of the year ended December 31, 2023 and 2022


For the year ended December 31, 2023, we generated total revenue, which includes product revenue and grant income, of approximately $36,349,000 as compared to revenues of approximately $34,689,000 for the year ended December 31, 2022, an increase of approximately $1,660,000, or 5%. Revenue from CytoSorb product sales was approximately $31,015,000 for the year ended December 31, 2023, as compared to approximately $28,573,000 in the year ended December 31, 2022, an increase of approximately $2,442,000, or 9%. Other product revenue was approximately $70,000 for the year ended December 31, 2023, as compared to $787,000 for the year ended December 31, 2022, a decrease of approximately $717,000. COVID-19 product sales were $0 in 2023 and approximately $300,000 in 2022. Direct sales increased by approximately $928,000, or 5% and distributor sales increased by approximately $797,000, or 7% during the year ended December 31, 2023, as compared to the year ended December 31, 2022. The increase in the average exchange rate of the Euro to the U.S. dollar also positively impacted 2023 product sales by approximately $780,000. For the year ended December 31, 2023, the average exchange rate of the Euro to the U.S. dollar was $1.08 as compared to an average exchange rate of $1.05 for the year ended December 31, 2022.

Grant income was approximately $5,264,000 for the year ended December 31, 2023, as compared to approximately $5,329,000 for the year ended December 31, 2022, a decrease of approximately $65,000, or 1%.

Cost of Revenue:

For the years ended December 31, 2023 and 2022, cost of revenue was approximately $13,957,000 and $13,956,000, respectively. Grant cost of revenue increased approximately $41,000 during the year ended December 31, 2023, as compared to the year ended December 31, 2022. Product cost of revenues decreased approximately $39,000 during the year ended December 31, 2023, as compared to the year ended December 31, 2022. Product gross margins were approximately 72% for the year ended December 31, 2023, and approximately 70% for the year ended December 31, 2022. This increase was primarily due to inefficiencies related to the relocation of our production activities to our new manufacturing facility in Princeton, New Jersey during the year ended December 31, 2022, that did not recur in 2023.

Gross Profit:

Gross profit was approximately $22,392,000 for the year ended December 31, 2023, an increase of approximately $1,659,000 or 8%, versus gross profit of $20,733,000 in 2022. This increase is attributed to increased sales and the increase in product gross margin percentage as discussed above.

Research and Development Expenses:

Our research and development costs were approximately $15,729,000 and $15,119,000 for the years ended December 31, 2023 and 2022, respectively, an increase of approximately $610,000, or 4%. This increase was related to approximately $850,000 of costs incurred related to pre-production manufacturing activities required to bring the new manufacturing plant to a state of commercial readiness and approximately $720,000 of costs related to pre-commercialization activities related to DrugSorb ATR. These increases were offset by a decrease in clinical trial related costs of approximately $940,000, due primarily to the termination of our STAR-D clinical trial in the U.S., and other non-grant related research and development costs of approximately $20,000.

Legal, Financial and Other Consulting Expenses:

Our legal, financial and other consulting costs were approximately $4,272,000 and $2,848,000 for the years ended December 31, 2023 and 2022, respectively, an increase of approximately $1,424,000, or 50%. This increase was due to an increase in legal fees of approximately $1,010,000 due to the abandonment of certain issued patents and patent applications, fees related to Company’s equity transactions and the settlement of a litigation matter; an increase in employment agency fees of approximately $178,000 related to the hiring of certain management personnel, an increase in consulting fees of approximately $179,000 related to regulatory matters on DrugSorb-ATR and an increase in accounting fees of approximately $57,000.

Selling, General and Administrative Expenses:

Our selling, general and administrative expenses were approximately $33,600,000 and $34,288,000 for the years ended December 31, 2023 and 2022, respectively, a decrease of approximately $688,000, or 2%. This decrease was due to a decrease in sales and marketing costs, which include advertising and conference attendance, of approximately $839,000, a decrease in royalty expense of approximately $109,000, a decrease in non-cash stock compensation expense (which includes both stock options and restricted stock units) of approximately $115,000, a decrease in commercial insurance of approximately $165,000 and a decrease in public relations costs of approximately $135,000. These decreases were offset by an increase in salaries, commissions, and related costs of approximately $532,000 and an increase in other general and administrative costs of approximately $143,000.

Gain (Loss) on Foreign Currency Transactions:

For the year ended December 31, 2023, the gain on foreign currency transactions was approximately $1,949,000, as compared to a loss on foreign currency transactions of approximately $2,449,000 for the year ended December 31, 2022. The 2023 gain is directly related to the increase of the exchange rate of the Euro as of December 31, 2023, as compared to December 31, 2022. The exchange rate of the Euro to the U.S. dollar was $1.11 per Euro as of December 31, 2023, as compared to $1.07 per Euro at December 31, 2022. The 2022 loss is directly related to the decrease in the exchange rate of the Euro as of December 31, 2022, as compared to December 31, 2021. The exchange rate of the Euro to the U.S. dollar was $1.07 per Euro as of December 31, 2022, as compared to $1.14 per Euro at December 31, 2021.

Benefit from Income Taxes:

Our benefit from income taxes was approximately $814,000 and $1,093,000 for the years ended December 31, 2023 and 2022, respectively. These benefits were realized by utilizing the New Jersey Technology Business Tax Certificate Transfer Program whereby the State of New Jersey allows us to sell a portion of our state net operating losses to a third party.

Liquidity and Capital Resources

Since inception, our operations have been primarily financed through the issuance of debt and equity securities. As of December 31, 2023, we had current assets of approximately $25.7 million and current liabilities of approximately $14.5 million. As of December 31, 2023, $25 million of our total shelf amount was allocated to our ATM facility, of which approximately $20.3 million remained available. During the year ended December 31, 2023, the Company sold 2,656,464 shares pursuant to the Sale Agreement, at an average selling price of $1.76 per share, generating net proceeds of approximately $4,532,000.

In April of 2023, we received approximately $1,000,000 in cash from the approved sale of our net operating losses and research and development credits from the State of New Jersey. In March of 2024, we received approximately $880,000 in cash from the approved sale of our net operating losses and research and development credits from the State of New Jersey.

On December 13, 2023, the Company closed on a registered direct offering for the sale, directly to investors, of 7,733,090 shares of registered common stock and warrants to purchase up to 2,706,561 shares of common stock (the “Offering”). Each share of common stock and accompanying warrant to purchase up to 0.35 shares of common stock, were sold together for a combined purchase price of $1.33, for an aggregate purchase price of approximately $10,285,000. After deducting transaction fees and expenses payable by the Company in connection with the Offering, the Company received net proceeds of approximately $9,785,000, excluding any proceeds that may be received upon the exercise of the warrants. Each warrant is immediately cash exercisable at an exercise price of $2.00 per share and will expire on the fifth anniversary of the issue date.

We are also managing our resources proactively, continuing to invest in key areas such as our U.S. and Canadian pivotal STAR-T trial, which includes the detailed analysis of trial data and the preparation of our application for marketing approval to the U.S. FDA and Health Canada. We have also instituted and continue to maintain tight control over expenditures.

As of December 31, 2023, we have approximately $15.6 million in cash, including approximately $14.1 million and $1.5 million in unrestricted and restricted cash, respectively. We believe this is sufficient to fund the Company’s operations into the fourth quarter of 2024. We will need to raise additional capital to support our ongoing operations in the future, and the Company is actively pursuing financing sources, including less or non-dilutive debt financing, royalty financing, strategic or direct investments, equity financing, and/or combinations thereof. There can be no assurance that management will be successful in these endeavors.

About CytoSorbents Corporation (NASDAQ: CTSO)

CytoSorbents Corporation is a leader in the treatment of life-threatening conditions in the intensive care unit and in cardiac surgery through blood purification. Its lead product, CytoSorb®, is approved in the European Union and distributed in 75 countries worldwide. It is an extracorporeal cytokine adsorber that reduces “cytokine storm” or “cytokine release syndrome” in common critical illnesses that can lead to massive inflammation, organ failure and patient death. In these diseases, the risk of death can be extremely high, and there are few, if any, effective treatments. CytoSorb is also used during and after cardiothoracic surgery to remove antithrombotic drugs and inflammatory mediators that can lead to postoperative complications, including severe bleeding and multiple organ failure. At the end of 2023, more than 228,000 CytoSorb devices had been used cumulatively. CytoSorb was originally launched in the European Union under CE mark as the first cytokine adsorber. Additional CE mark extensions were granted for bilirubin and myoglobin removal in clinical conditions such as liver disease and trauma, respectively, and for ticagrelor and rivaroxaban removal in cardiothoracic surgery procedures. CytoSorb has also received FDA Emergency Use Authorization in the United States for use in adult critically ill COVID-19 patients with impending or confirmed respiratory failure. The DrugSorb™-ATR antithrombotic removal system, based on the same polymer technology as CytoSorb, also received two FDA Breakthrough Device Designations, one for the removal of ticagrelor and another for the removal of the direct oral anticoagulants (DOAC) apixaban and rivaroxaban in a cardiopulmonary bypass circuit during urgent cardiothoracic procedures. The Company has completed the FDA-approved, randomized, controlled STAR-T (Safe and Timely Antithrombotic Removal-Ticagrelor) study of 140 patients at approximately 30 centers in U.S. and Canada to evaluate whether intraoperative use of DrugSorb-ATR can reduce the perioperative risk of bleeding in patients receiving ticagrelor and undergoing cardiothoracic surgery. This pivotal study is intended to support U.S. FDA and Health Canada marketing approval for DrugSorb-ATR in this application.

CytoSorbents’ purification technologies are based on biocompatible, highly porous polymer beads that can actively remove toxic substances from blood and other bodily fluids by pore capture and surface adsorption. Its technologies have received non-dilutive grant, contract, and other funding of approximately $50 million from DARPA, the U.S. Department of Health and Human Services (HHS), the National Institutes of Health (NIH), National Heart, Lung, and Blood Institute (NHLBI), the U.S. Army, the U.S. Air Force, U.S. Special Operations Command (SOCOM), Air Force Material Command (USAF/AFMC), and others. The Company has numerous marketed products and products under development based upon this unique blood purification technology protected by many issued U.S. and international patents and registered trademarks, and multiple patent applications pending, including ECOS-300CY®, CytoSorb-XL™, HemoDefend-RBC™, HemoDefend-BGA™, VetResQ®, K+ontrol™, DrugSorb™, ContrastSorb, and others.  For more information, please visit the Company’s websites at and or follow us on Facebook and X (fka Twitter).
