Eligibility Criteria  ICMJE

Patient Inclusion Criteria:

  • Patient has confirmed positivity for SARS-CoV-2 as measured by rRT-PCR or other approved test to detect SAR-CoV-2 per institutional practice.

  • Patient is ≥ 18 years of age at the time of signing the Study informed consent form (ICF).
  • Patient understands and voluntarily signs the Study ICF prior to any study-related assessments/procedures are conducted.
  • Patient is willing and able to adhere to the study schedule and other protocol requirements.
  • SpO2 ≥ 88% on room air; oxygen is permitted as delivered by nasal cannula and/or face mask at any flow rate to achieve this SpO2. Patients must have an SpO2 ≥ 92% if on supplementary oxygen.
  • Ability to be off immunosuppressive drugs for 3 days prior to infusion, unless clinically indicated. Steroids are permitted if clinically indicated and at the discretion of the treating physician. If clinically indicated, careful consideration should be taken regarding the timing and tapering of high-dose steroids.

    • FCBP is a female who: 1) has achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral oophorectomy or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).
  • Male Patients must agree to use a condom during sexual contact for at least 28 days following the last infusion of CYNK-001, even if he has undergone a successful vasectomy.

Patient Exclusion Criteria

  • Patient requires supplemental oxygen delivered by mechanical ventilation, either invasive or bilevel positive airway pressure.
  • Patient admitted to Intensive Care Unit / Pulmonary Acute Care Unit designated area with severe pulmonary pneumonia, ARDS or Sepsis.
  • Patient is pregnant or breastfeeding.
  • Patient has a history of chronic asthma requiring ongoing medical therapy or other chronic pulmonary disease that, at the discretion of the treating physician, would contraindicate participation in this study.
  • Patient has any other organ dysfunction [Common Terminology Criteria for AEs (CTCAE) Version 5.0 Grade 3] that will interfere with the administration of the therapy according to this protocol.
  • Patient has inadequate organ function as defined below at time of Treatment Eligibility Period:

    1. Patient has aspartate aminotransferase (AST), alanine aminotransferase (ALT), or alkaline phosphatase ≥ 5 x the upper limit of normal (ULN). (It is anticipated that the infection may impact liver.)
    2. Estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m^2 as calculated using the Modification of Diet in Renal Disease Study equation (Levey, 2006) or history of an abnormal eGFR < 60. A decline of > 15 mL/min/1.73 m^2 below normal in the past year prior to infection. (It is anticipated that the infection may impact renal function.)
    3. Patient has a bilirubin level > 2 mg/dL (unless Patient has known Gilbert's Syndrome).
  • Patient has a known sensitivity or allergy to treatment additives or diluent substances of dimethyl sulfoxide (DMSO), PlasmaLyte A or human serum albumin (HSA). Please refer to investigational brochure (IB).

    4. Carcinoma in situ of the breast
    5. Incidental histological finding of prostate cancer (TNM stage of T1a or T1b)
  • Detection of other respiratory viruses from mucosal surfaces that would interfere with the study treatment plan; detection of another respiratory virus is not in itself an exclusion criteria unless the investigator believes it would interfere with administration of CYNK-001.
  • Patient must not have a history of unconsciousness or hemoptysis within 2 weeks of signing informed consent form.
  • Patients must not have a history of unconsciousness or hemoptysis within 2 weeks of signing ICF.
  • Patients must not have end stage liver disease and/or cirrhosis.
  • Patient has any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the patient from participating in the study.
  • Patient has any condition including the presence of laboratory abnormalities which places the patient at unacceptable risk if he or she were to participate in the study.
