Information provided by (Responsible Party):
University of California, San Francisco
  Purpose
The overall objective of this pilot project is to evaluate the safety and efficacy of the gastric submucosal space as a novel site for clinical islet transplantation. The site has several physiologic attributes that may improve the outcomes of islet transplantation compared with the conventional intraportal transplant site.

Criteria

Inclusion Criteria:

Key Inclusion Criteria:

  3. One or more of the following signs or symptoms despite intensive efforts made in close cooperation with their diabetic care team:

    • Metabolic lability/instability characterized by hypoglycemia or ketoacidosis (>2 hospital admissions in the previous year), erratic glucose profiles (MAGE>120 mg/dL), or disruption in lifestyle of danger to life, self or others
    • Reduced awareness of hypoglycemia or >1 episode in the last 1.5 years of severe hypoglycemia
    • Persistently poor glucose control (as defined by HgbA1c>10% at the end of six months of Intensive management efforts with the diabetes care team)
    • Progressive secondary complications as defined by (i) a new proliferative retinopathy or clinically significant macular edema or therapy with photocoagulation during the last year; or (ii) symptomatic autonomic neuropathy (as defined by postural hypotension or neuropathic bladder)
  4. Age 18 and older
  5. Patients who have a renal transplant must have received their transplant at least 3 months previously and must have stable renal function (see exclusion criteria below)

Exclusion Criteria:

Key Exclusion Criteria:

  2. Presence of panel-reactive anti-HLA antibody >20%
  3. Positive lymphocytotoxic cross-match using donor lymphocytes and serum
  4. Evidence of acute EBV infection (IgM>IgG) OR no serologic evidence of previous exposure to EBV (IgG>IgM)
  5. Calculated or measured GFR < 50 ml/min/m2 in patients without a renal transplant.
  6. Calculated or measured GFR < 40 ml/min/m2 in patients with a renal transplant.
  7. Portal hypertension or history of significant liver disease
  8. History of malignancy within 10 years (except for treated basal or squamous cell CA of the skin)
  9. Active peptic ulcer disease or other gastric mucosal abnormalities as identified on screening endoscopy
  10. Severe unremitting diarrhea or other GI disorders potentially interfering with the ability to absorb oral medications
  11. Untreated proliferative retinopathy
  12. Pregnancy or breastfeeding
  13. Female subjects not post-menopausal or surgically sterile who are sexually active but not using an acceptable method of contraception
  14. Active infections
  15. Serologic evidence of infection with HIV, or HbsAg or HCV Ab positive
  16. Major ongoing psychiatric illness
  17. Ongoing substance abuse, drug or alcohol; or recent history of noncompliance
  18. Any condition that in the opinion of the Principal Investigator does not allow safe participation in the study
