Vertex Presents Positive, Updated VX-880 Results From Ongoing Phase 1/2 Study in Type 1 Diabetes at the European Association for the Study of Diabetes 59th Annual Meeting
- All patients treated with VX-880 in Parts A and B have follow-up data beyond Day 90 and have demonstrated islet cell engraftment and glucose-responsive insulin production -
- All patients showed improvement across all measures of glucose control, including decreases in HbA1c, increases in blood glucose time-in-range, and reduction or elimination of insulin use -
- The two patients with at least 1 year of follow-up met the criteria for the primary endpoint of elimination of severe hypoglycemic events (SHEs) and HbA1c <7.0% -
- VX-880 was generally well tolerated -
- Part C concurrent dosing well underway -
All patients in Part A and B now have more than 90 days of follow-up and have demonstrated islet cell engraftment and endogenous glucose-responsive insulin production on the Day 90 mixed-meal tolerance test (MMTT). All patients demonstrated improved glycemic control across all measures, including decreases in HbA1c, improved time-in-range on continuous insulin monitoring, and reduction or elimination of exogenous insulin use.
The two patients with at least 12 months of follow-up after VX-880 infusion, who were therefore evaluable for the study’s primary efficacy endpoint, met the criteria for the primary endpoint of elimination of SHEs between Day 90 and Month 12 with an HbA1c <7.0%. The first patient achieved insulin independence at Day 270 through Month 24. This is a patient who has had T1D for nearly 42 years and prior to trial enrollment was on 34 units of daily exogenous insulin. The second patient achieved insulin independence at Day 180 through Month 12. This is a patient who has had T1D for 19 years and prior to trial enrollment was on 45.1 units of daily exogenous insulin. Starting at Month 15, this patient was started on four units of basal insulin daily, at the investigator’s discretion. After the data cut-off date, a third patient achieved insulin independence at Day 180.
VX-880 has been generally well tolerated in all patients dosed to date. The majority of adverse events (AEs) were mild or moderate, and there were no serious AEs related to VX-880 treatment. As previously reported, one subject had SHEs in the perioperative period. There have been no other SHEs in the study.
“We continue to marvel at the impressive data from the VX-880 program as evidenced by the improvements in all treated patients across all glycemic measures,” said
“These data are particularly meaningful in the context of our overall investigational T1D program, as these same VX-880 cells are the foundation for our VX-264 cells-plus-device program, and our hypoimmune islet cell program,” said
These data were presented during the
VX-880 is an investigational allogeneic stem cell-derived, fully differentiated, insulin-producing islet cell therapy manufactured using proprietary technology. VX-880 is being evaluated for patients who have T1D with impaired hypoglycemic awareness and severe hypoglycemia. VX-880 has the potential to restore the body’s ability to regulate glucose levels by restoring pancreatic islet cell function, including glucose responsive insulin production. VX-880 is delivered by an infusion into the hepatic portal vein and requires chronic immunosuppressive therapy to protect the islet cells from immune rejection. The VX-880 trial has expanded to additional sites that are currently active and enrolling in the

About the VX-880 Phase 1/2 Clinical Trial
The clinical trial is a Phase 1/2, multi-center, single-arm, open-label study in patients who have T1D with impaired hypoglycemic awareness and severe hypoglycemia. This study is designed as a sequential, multi-part clinical trial to evaluate the safety and efficacy of VX-880. Approximately 17 patients will be enrolled in the clinical trial. Enrollment in Part C of the study is ongoing and multiple patients have been dosed.
VX-264 is an investigational cell therapy in which allogeneic human stem cell-derived islets are encapsulated in a channel array device designed to shield the cells from the body’s immune system. VX-264 is designed to be surgically implanted and is currently being evaluated for patients with T1D.
About the VX-264 Phase 1/2 Clinical Trial
The clinical trial is a Phase 1/2, single-arm, open-label study in patients who have T1D. This will be a sequential, multi-part clinical trial to evaluate the safety, tolerability, and efficacy of VX-264. Approximately 17 patients will be enrolled in the global clinical trial. Enrollment is ongoing in this study.
About Type 1 Diabetes
T1D results from the autoimmune destruction of insulin-producing islet cells in the pancreas, leading to loss of insulin production and impairment of blood glucose control. The absence of insulin leads to abnormalities in how the body processes nutrients, leading to high blood glucose levels. High blood glucose can lead to diabetic ketoacidosis and, over time, to complications such as kidney disease/failure, eye disease (including vision loss), heart disease, stroke, nerve damage, and even death.
Due to the limitations and complexities of insulin delivery systems, it can be difficult to achieve and maintain balance in glucose control in people with T1D. Current standards of care do not address the underlying causes of the disease, and there are limited treatment options beyond insulin for the management of T1D; there is currently no cure for diabetes.
