Brief summary
Inhibition of CXCL8 activity might represent a relevant therapeutic target to prevent injury occurring after pancreatic islet transplantation. Reparixin is a novel and specific inhibitor of CXCL8. This study is designed to explore the efficacy of reparixin in preventing graft dysfunction after islet transplantation in type 1 diabetes patients (T1D).
Detailed description
Pancreatic islet transplantation has become a feasible option in the treatment of T1D which offers advantages over whole pancreas transplantation. However to date insulin independence can be obtained in most cases only after the patient has received repeated infusions from several donors. A non-specific immune response, mediated predominantly by innate inflammatory processes, coupled with specific cellular immune responses, possibly promoted by early inflammation, play a major role in the loss of transplanted islets from the liver. PMNs have been found to be the predominant cell types infiltrating in vitro the islets. In this regard, CXCL8 has been shown to be expressed by human islets and could play a crucial role in triggering the inflammatory reaction. Thus, CXCL8 might represent a relevant therapeutic target to prevent early graft failure. The efficacy of reparixin in improving graft outcome in mice models of intrahepatic islet transplantation, as well as the safety shown in human phase 1 and 2 studies, provide a rationale for a clinical study aimed at evaluating the effect of reparixin in preventing graft dysfunction after islet transplantation in T1D patients.

| Beta-cell Function as Assessed by Beta-score | Months 1, 3, 6, 12 post-transplant | The beta-score provides a simple clinical scoring system that encompasses glycemic control, diabetes therapy, and endogenous insulin secretion that correlates well with physiological measures of beta-cell function. On this basis, it is suitable as an overall measure of beta-cell transplant function. Beta score is a composite scoring system based on fasting plasma glucose values, HbA1c, insulin independence or use of insulin/OHAs, and the determination of stimulated C-peptide levels. Normal values are given a score of 2, intermediate values merit a score of 1, and clearly abnormal values garner no points. Thus, a perfect score is 8, and a score of 0 indicates absolute absence of beta-cell function. |
| Beta-cell Function as Assessed by TEF/IEQ/kg Ratio | At months 1, 3, 6 after transplant 1 and months 1,3, 6, and 12 after transplant 2 | The TEF/IEQ/kg ratio is a parameter to assess transplant efficiency corrected by the number of transplanted islets. |
| Serum Level of Alanine Amino Transferase (ALT) | Pre-transplant and at days 1-7 and months 1 and 3 post-transplant | ALT is commonly measured clinically as part of liver function tests. |
| Serum Level of Aspartate Amino Transferase (AST) | Pre-transplant and at days 1-7 and months 1 and 3 post-transplant | AST is commonly measured clinically as part of liver function tests. |

A total of 9 patients were enrolled into the study; 6 were randomized to reparixin and 3 to the control group. All in the control group and 2 in the reparixin group were withdrawn after Transplant 1 due to graft loss. 4 in the reparixin group received Transplant 2. Thereafter, 1 was withdrawn due to graft loss. 1 was lost to follow-up.
Participants by arm
| Arm | Count |
|---|---|
| Reparixin Reparixin + Immunosuppression
Reparixin was administered at a dose of 2.772 mg/kg body weight/hour for 7 days (168 hours) at each transplant. It was administered as a continuous IV infusion into a (high-flow) central vein. Investigational Product infusion was to begin approximately 12 hours (range between 6 to 16 hours) before each pancreatic islet infusion was started. The Investigator identified the time to start study drug administration.
Reparixin was given to all patients of this arm using the same dosing solution (reparixin 11.00 mg/mL), but the pump rate was adjusted to provide an infusion rate of approximately 0.25 mL/kg/hour.
For immunosoppression regimen see the other arm description.
Reparixin: Reparixin + immunosuppression | 6 |
| No Experimental Intervention Immunosuppression only. Induction: First islet infusion: anti-thymocyte globulin (ATG), administered IV (central vein) at the dose of 1.5 mg/kg on Day -1, 0, 1, and 2 of islet infusion. The first ATG injection was preceded by a bolus IV injection of 500 mg methylprednisolone. Induction for the second islet infusion was to be administered per center practice. Maintenance: Mycophenolate mofetil (MMF), administered orally at the dose of 1 g twice a day, starting on Day -1 of the first islet infusion; Tacrolimus, administered orally starting on Day -1 of the first islet infusion at a dose of 0.087 mg/kg twice a day. Thereafter, dosing was to be targeted to blood trough levels of 8 to 10 ng/mL. Administration continued up to Month 3 after the first transplant. Rapamycin was to replace tacrolimus from Month 3 after the first transplant. It was to be administered orally at the starting dose of 0.1 mg/kg once a day, then targeted to a blood trough level of 10 to 12 ng/mL. | 3 |

Beta-cell Function as Assessed by Beta-score
The beta-score provides a simple clinical scoring system that encompasses glycemic control, diabetes therapy, and endogenous insulin secretion that correlates well with physiological measures of beta-cell function. On this basis, it is suitable as an overall measure of beta-cell transplant function. Beta score is a composite scoring system based on fasting plasma glucose values, HbA1c, insulin independence or use of insulin/OHAs, and the determination of stimulated C-peptide levels. Normal values are given a score of 2, intermediate values merit a score of 1, and clearly abnormal values garner no points. Thus, a perfect score is 8, and a score of 0 indicates absolute absence of beta-cell function.
Time frame: Months 1, 3, 6, 12 post-transplant
Population: Efficacy Population: All patients who were randomized and received the transplant were included in the efficacy population.

Time to Achieve Insulin-independence After the Transplant 2
Time to achieve insulin-independence after the transplant was defined as the number of days between islet infusion and onset of insulin-independence. This was calculated as: date of onset of insulin-independence minus the islet infusion date.
Time frame: up to 1 year after transplant 2
Population: Efficacy Population: All patients who were randomized and received the transplant were included in the efficacy population
| Arm | Measure | Value (MEAN) | Dispersion |

| Reparixin | Time to Achieve Insulin-independence After the Transplant 2 | 66.3 days | Standard Deviation 73.7 |
Total Time of Insulin Independence After the Transplant
Total time of insulin-independence after the transplant. This was defined as the number of days between the onset and loss of insulin-independence and was calculated as the date of loss of insulin-independence minus the date of onset of insulin-independence. Of the 3 patients who achieve insulin-independence after transplant 2, only 2 remained insulin-independent up to 1 year and the mean (SD) total time of insulin-independence after the second transplant was 276 (96.2) days with a range between 208 and 344 days.
Time frame: up to 1 year after transplant 2
Population: Efficacy Population: All patients who were randomized and received the transplant were included in the efficacy population.
