The purpose of this study is to determine if the combination of oral cyclosporine, an immune therapy and oral omeprazole, a proton pump inhibitor, are effective in rendering insulin independence among recent onset type 1 diabetes patients. This two-arm study is designed to evaluate the safety and efficacy for insulin independence of two FDA and EMA-approved therapies among recent onset type 1 diabetes patients.

One of the greatest new insights of today in the field of type 1 diabetes, is the understanding that in man, unlike the success seen in type 1 diabetes mouse models, there is no beta cell regeneration with immune therapy alone. In man, type 1 diabetes is now considered to be a disease of both autoimmunity and lack of beta cell regeneration (Levetan 2103).

More than 500 patients with new onset type 1 diabetes have been given cyclosporine and some studies have demonstrated as high as a 57% insulin-free remission rate that was not sustained due to the lack of beta cell regeneration (Feutren 1986, Bougneres 1988, Eisenbarth 1989, Sobel 2010). Studies among diabetes patients with proton pump inhibitors have shown the potential to increase beta cell mass by 40%, but among type 1 patients without immune protection, such outcomes cannot be not achieved (Singh 2012, Griffin 2014).

The usage of a beta cell regeneration agent such as omeprazole, in combination with an immune tolerance, like cyclosporine, provides both the potential ability to maintain and regenerate beta cells. This is a new paradigm for the treatment of new onset type 1 diabetes.

More than 60 human trials have been conducted among type 1 diabetes with a variety of different therapies aimed at preventing autoimmune attack on insulin-producing beta cells. None have been as effective as cyclosporine in both slowing the decline in beta cell mass and resulting in the potential for insulin-free remissions. (Canadian-European Randomized Control Trial 1988, Eisenbarth 1989, Skyler 1992, Sobel 2010).

Because cyclosporine is known for its potential side-effects, most notably in the kidney, all previous studies among type 1 patients have carefully monitored kidney function. Follow-up studies for up to 13 years among 285 type 1 patients utilizing cyclosporine for 20 months did not demonstrate renal or other side effects at the dosages that will be used in this trial (Assan 2002).

The most effective initiating dosage for insulin independence in the cyclosporine trials was 7.5 mg/kg/day, but for safety, this study will begin at a lower dosage of 5 mg/kg/day and will monitor kidney function and cyclosporine levels initially on a weekly basis. This study will use only those dosages of cyclosporine that have not demonstrated toxicity to the kidney or resulted in non-reversible side effects among more than 500 patients with recent onset type 1 diabetes treated with cyclosporine.

Omeprazole has been shown to significantly increase gastrin levels which is associated with increased beta cells. Lansoprazole has also been shown to be safe among patients with new onset type 1 diabetes for one year with a trend toward increased beta cell mass among patients with higher gastrin levels.

In a randomized trial for 12 weeks among 56 patients undergoing pancreatectomy, those randomized to receive a proton pump inhibitor had significantly increased gastrin levels, higher insulin levels and improved endocrine function by glucose tolerance testing and less pancreatic atrophy as measured by CT scans (Jang 2003).

The recently completed REPAIR T1D trial among newly diagnosed type 1 patients used a proton pump inhibitor and GLP-1 therapies for 1 year for beta regeneration failed to meet its endpoint of increased stimulated C-peptide. Lack of maintenance or regeneration of beta cells was specifically noted to have likely been due to lack of usage of immune therapy to protect beta cells (Griffin 2014, Rigby 2014).

Those patients in REPAIR T1D, who did achieve gastrin and GLP-1 levels above those in the control group had a trend towards improved preservation of C-peptide with a suggestion of a decreased rate of fall of C-peptide through 12 months (Griffin 2014 Appendix Supplemental data). Glucose levels also trended lower than controls in the intervention arm with gastrin levels above the control arm (Griffin 2014 Appendix Supplemental data). In humans, the newly forming beta cells are under the greatest immune attack among type 1 patients (Meier 2006). REPAIR T1D underscores the importance for both immune therapy with a regeneration therapy among type 1 patients (Griffin 2014, Rigby 2014).

The combination of cyclosporine with a proton pump inhibitor has the potential to demonstrate maintenance and expansion of residual beta cells. This combination therapy provides the unique ability for patients to become insulin independent.
