Vertex Wins FDA Clearance of Investigational New Drug Application for VX-880, a Novel Cell Therapy for the Treatment of Type 1 Diabetes
29 January 2021 - - The US Food and Drug Administration has cleared an IND, enabling US-based Vertex Pharmaceuticals Inc. (NASDAQ: VRTX) to proceed with initiating a clinical trial for VX-880, an investigational stem cell-derived, fully differentiated pancreatic islet cell therapy to treat T1D, the company said.

Vertex plans to initiate a Phase 1/2 clinical trial in the first half of 2021 in patients who have T1D with impaired hypoglycemic awareness and severe hypoglycemia.

VX-880, formerly known as STx-02, is an investigational allogeneic human stem cell-derived islet cell therapy that 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 insulin production.

The VX-880 clinical trial will involve an infusion of fully differentiated, functional islet cells, as well as the chronic administration of concomitant immunosuppressive therapy, to protect the islet cells from immune rejection.

The clinical trial is a Phase 1/2, single-arm, open-label study in subjects who have T1D with impaired hypoglycemic awareness and severe hypoglycemia.

This will be a sequential, multi-part clinical trial to evaluate the safety and efficacy of different doses of VX-880.

Approximately 17 patients will be enrolled in the clinical trial.

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 patients with T1D.

Hypoglycemia remains a critical limiting factor in glycemic management, and severe hypoglycemia can cause loss of consciousness, coma, seizures, injury, and can be fatal.

There are currently limited treatment options beyond insulin for the management of T1D.
