About this study
In plain language
This study tests how safe VX-880 and VX-017 infusions are, how well people tolerate them, and how well they work. It is for people with type 1 diabetes who have severe low blood sugar and trouble noticing when their blood sugar is low.
This study will evaluate the safety, tolerability and efficacy of VX-880 infusion and VX-017 infusion in participants with type 1 diabetes (T1D) and impaired awareness of hypoglycemia (IAH) and severe hypoglycemia.
Compensation is read from the study's own description and may be missing — always confirm with the study team.
Eligibility
Who can join
- Have type 1 diabetes and have needed insulin for at least 5 years.
- Have had at least 2 recorded episodes of severe low blood sugar in the 12 months before joining.
- Have a stable diabetes treatment plan.
- Have regularly used a continuous glucose monitor (CGM), a device that tracks blood sugar, for at least 3 months before screening and agree to use it throughout the study.
Who can't join
- Have had an islet cell transplant (cells that make insulin), an organ transplant, or cell therapy (treatment using cells).
- Other study rules may also affect who can join.
