Safety and Efficacy of CELZ-201 in Patients With Recent Onset Type 1 Diabetes

Prior treatment

• Subjects with any history of cardiac disease, including but not limited to myocardial infarction, uncompensated heart failure, fluid overload, as well as any clinically significant abnormality identified on prior cardiac stress test, angiogram evaluation, or echocardiogram.
• Recent recipient of any licensed or investigational live attenuated vaccine(s) within 6 weeks of randomization.
• Patients who have participated in previous clinical studies, other than observational studies, will be excluded.
• Concomitant therapy with immunosuppressive drugs, immunomodulators, or cytotoxic agents, or previous therapy less than 3 months from randomization.
• Diagnosed or self-reported drug or alcohol abuse.
• Known history of serious allergic reactions, including anaphylaxis to CELZ-201 or its preparation components. Specifically, patients with a prior history of heparin induced thrombocytopenia or any other adverse reaction to heparin, will be excluded.

Other illness

• Subjects with poorly controlled hypertension as defined by systolic blood pressure \>140 mmHg or diastolic blood pressure \>90 mmHg.
• Subjects with liver disease, portal hypertension, any coagulopathy (including history of Factor V deficiency) or long-term anti-coagulant therapy (except low-dose aspirin). Other hepatic conditions including hepatic anatomic abnormalities or variants that would place the individual at increased risk in the judgment of the investigator are also considered exclusionary.
• Symptomatic cholecystolithiasis; acute or chronic pancreatitis; or current symptomatic peptic ulcer disease.
• Subjects with uncontrolled thyroid disease: thyroid stimulating hormone \<0.3 mU/L or \>5 mU/L; free T4 \<5.0 ug/dL or \>11.0 ug/dL.
• Ongoing acute infections, e.g., acute respiratory tract, urinary tract, or gastrointestinal tract infections.
• Subjects with eating disorders.
• Ongoing or anticipated use of diabetes medications other than insulin.
• History or diagnosis of malignancy with the exception of a history of localized basal or squamous cell carcinoma.
• Any history of gastroparesis or other severe gastrointestinal disease.
• An individual who has a medical, psychological or social condition that, in the opinion of the Principal Investigator, would interfere with safe and proper completion of the trial.
• Positive for coronavirus disease (COVID)-19 by PCR or evidence of active infection per local institutional standards.
• Allergy to iodine contrast or anesthesia

Lab values

• HbA1c \> 9%
• Any of the following laboratory findings: hemoglobin \<11.5 g/dL (females) or \<13.2 g/dL (males); leukocytes \<3,000/μL; neutrophils \<1,500/μL; lymphocytes \<800/μL; platelets \<100,000/μL; elevation in AST and ALT \>2 x ULN (upper limit of normal); LDL cholesterol \>160; Triglycerides \>3 x ULN; total bilirubin \>1.5 x ULN.
• Screening laboratory evidence consistent with significant chronic active infection (i.e.., hepatitis B and C, tuberculosis, and HIV), and IGRA Tuberculosis (Tb) test during screening

Age

• Pregnancy or ongoing breastfeeding for women; unwillingness or inability of both females and males of childbearing age to use a reliable and effective form of contraception, for the entire 2-year duration of the study.

Other

• Inability or unwillingness of a subject to give written informed consent or comply with study protocol.
• BMI\>28 kg/m.
• Current or ongoing use of non-insulin pharmaceuticals that affect glycemic control within 7 days of screening.
• Presence of an allograft.
• Inability to perform any of the assessments required for endpoint analysis.
• The investigator believes that participating in the trial is not in the best interest of the patient, or the investigator considers patient unsuitable for enrollment (such as unpredictable risks or subject compliance issues).
• For female subjects: Pregnant, nursing, or planning to become pregnant during the course of entire duration of the study (approximately little over two years) or unwillingness to comply with contraceptive requirements.
• For male subjects: Male subjects with a female partner who is planning to become pregnant with the male subject during the entire course of the study or unwillingness to comply with contraceptive requirements.

• Subject must be able to understand and provide signed informed consent.
• Males and females, 18-35 years of age.
• Diagnosis of T1D within 1 year, with stimulated C-peptide peak level \>0.6 ng/mL as assessed by 4-hour MMTT at the time of Visit 0 (screening).
• Diagnosed with T1D, according to ADA standard criteria, and confirmed by positivity to at least two islet autoantibodies, GAD65, IA-2, or ZnT8.
• Mentally stable and able to comply with the procedures of the study protocol
• Subjects must be willing to comply with "standard-of-care" diabetes management.
• Subjects with eGFR \>80 ml/min/1.73m2
• Female subjects of childbearing potential must have a negative pregnancy test upon study entry.
• Female (and male) subjects with reproductive potential must agree to use two FDA approved methods of birth control for the entire duration of the study.
  • Potential subjects of childbearing potential should agree to use effective contraception for the entire 2-year period.
• Adequate venous access to support study required blood draws.
