Current Primary Outcome Measures  ICMJE
 (submitted: October 11, 2017)
  • Number of Participants With Any Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Up to Month 24 ]
    AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE include adverse events that result in any of the following outcomes: death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, a persistent or significant incapacity or substantial disruption of the ability to conduct normal functions, or a congenital anomaly/birth defect. Important medical events that may not result in death, be life-threatening, or require hospitalization may be considered serious when, based upon appropriate medical judgment, they may jeopardize the participant and may require medical or surgical intervention to prevent one of the outcomes listed in this definition.
  • Number of Participants With Cytokine Release AE [ Time Frame: Up to Month 24 ]
    AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Cytokine release AEs were defined as occurring during dosing or within a limited time window after the last dose.
  • Number of Participants With Abnormal Hematology Values of Potential Clinical Concern (PCC) [ Time Frame: Up to Month 48 ]
    Hematology parameters: hemoglobin, white blood cell (WBC) count, basophils, eosinophils, lymphocytes, monocytes, neutrophils, platelet count, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration were assessed for abnormal PCC values. Data for abnormal parameters (high and low) is presented. Only those parameters for which at least one value of PCC was reported are summarized.
  • Number of Participants With Abnormal Clinical Chemistry Values of PCC [ Time Frame: Up to Month 48 ]
    Clinical chemistry parameters: alkaline phosphatase, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, gamma-glutamyl transferase, lactate dehydrogenase, lipids, blood urea nitrogen, creatinine, uric acid, sodium, potassium, chloride, carbon dioxide, creatinine phosphokinase, albumin, calcium, magnesium, glucose, phosphate, bicarbonate and total protein were assessed for abnormal PCC values. Data for abnormal parameters (high and low) is presented. Only those parameters for which at least one value of PCC was reported are summarized.
  • Number of Participants With Abnormal Urinalysis Dipstick Results [ Time Frame: Up to Month 48 ]
    Urinalysis parameters: Occult blood, Glucose urine, Ketones, Leukocyte esterase, Nitrite, pH, Protein urine were assessed. Abnormal values for occult blood and ketones were presented as 1+, 2+ and 3+ (the plus sign increases with a higher level of parameters: 1+=slightly positive, 2+=positive, 3+=high positive). Abnormal glucose urine values were presented as 50, 100, 250 and 1000 mg/dL. Abnormal nitrite values were presented as 'positive', and abnormal urine protein values were presented as 30 and 100 mg/dL.
  • Mean Overall Maximum Cytokines Level [ Time Frame: Up to Week 8 ]
    Levels of cytokines: interferon (IFN)-gamma, interleukin (IL)-10, IL-6 and tumor necrosis factor (TNF)-alpha were assessed. One sample was collected at Baseline, on dose Day 1 at 1, 2, 3, and 8 hours post-end of infusion (EOI) and on all other dosing days at pre-dose, and 1, 2, 3, and 8 hour post-EOI. After the completion of dosing, on Day 21 and Week 8, only the IL-10 level was assessed in the cytokine blood sample.
  • Number of Participants With Positive Epstein Barr Virus (EBV) Viral Load [ Time Frame: Up to Month 18 ]
    EBV load was measured using quantitative polymerase chain reaction (PCR) method. If a participant had an EBV viral load of >100,000 copies/10^6 peripheral blood mononuclear cells (c/10^6 PBMC) lymphocytes at any time post-dose, the test was repeated immediately. Data for participants with abnormal viral load is presented.

  • Number of Participants With Use of Analgesics, Antihistamines and IV Hydration as Concomitant Medication During Dosing Days [ Time Frame: Up to Day 8 ]
    Ibuprofen (analgesic) was given orally as follows: 400-800 mg 2 hour before SOI, 400-800 mg 2 hour after SOI, 400-800 mg 6 hour after SOI, and 400-800 mg at bedtime. If ibuprofen was contraindicated, acetaminophen was used in place of ibuprofen. Acetaminophen doses were adjusted so as it did not exceed 1000 mg per 6 hour or 4000 mg per day. A non-sedating antihistamine (cetirizine) was administered approximately 1 hour prior to each infusion of study drug. The recommended initial dose of cetirizine was 5 mg or 10 mg per day in adults and children aged 12 years and older. Normal saline solution was administered IV as needed to maintain hydration.
  • Change From Baseline in Percent Glycosylated Hemoglobin (HbA1c) [ Time Frame: Baseline and up to Month 48 ]
    Participants were seen weekly during the first 4 weeks post-dose and then every other week through Week 12. After Week 12, visits occurred every 1 to 3 months through Month 18, which completes the Core Study up to Month 48 (follow up). Day 1 pre-dose value was considered as Baseline value. Change from Baseline was post-Baseline value minus Baseline value.
