 clinical trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. Approved autologous T cell therapies and those under development by other companies have shown frequent rates of CRS, neurotoxicity, serious infections, prolonged cytopenia and hypogammaglobulinemia, and adverse events have resulted in the death of patients. Similar adverse events may occur for our T cell product candidates. In addition, we utilize a lymphodepletion regimen, which generally includes fludarabine and cyclophosphamide, that may cause serious adverse events. For instance, because the regimen will cause a transient and sometimes prolonged immune suppression, patients will have an increased risk of infection, such as to COVID-19, that may be unable to be cleared by the patient and ultimately lead to other serious adverse events or death. Our lymphodepletion regimen has caused and may also cause prolonged cytopenia and aplastic anemia. We may also combine the use of our product candidates with other investigational or approved therapies that may cause separate adverse events or events related to the combination or potentiate side effects of approved drugs. 33 If unacceptable toxicities arise in the development of our product candidates, we could suspend or terminate our trials or the FDA, the EMA or comparable foreign regulatory authorities could order us to cease clinical trials or deny approval of our product candidates for any or all targeted indications. Any data safety monitoring board may also suspend or terminate a clinical trial at any time on various grounds, including a finding that the research patients are being exposed to an unacceptable health risk, including risks inferred from other unrelated immunotherapy trials. Treatment-related side effects could also affect patient recruitment or the ability of enrolled subjects to complete the trial or result in potential product liability claims. In addition, these side effects may not be appropriately recognized or managed by the treating medical staff, as toxicities resulting from T cell therapy are not normally encountered in the general patient population and by medical personnel. Inadequate training in recognizing or managing the potential side effects of our product candidates could result in patient deaths. Any of these occurrences may harm our business, financial condition and prospects significantly. Our product candidates may target healthy cells expressing target antigens, leading to potentially fatal adverse effects. Our product candidates target specific antigens that are also expressed on healthy cells. For example, cell surface phosphatidylserine, the target of CER-1236, has been observed on activated immune cells, including platelets, and in rapidly dividing cells across various organs including the gastrointestinal
