E-islet 01 therapy for people with long-standing Type 1 diabetes and impaired hypoglycemia awareness

Official title: A Phase 1/2a Study to Evaluate the Safety, Tolerability, and Efficacy of E-islet 01 in Subjects Who Have Type 1 Diabetes Mellitus With Impaired Hypoglycemic Awareness and Severe Hypoglycemia

Run by EndoCell Therapeutics, Inc. · NCT07126873 · Data updated 2026-11-12

This trial will test whether E-islet 01, an allogeneic human islet cell therapy, is safe and helps reduce severe or unrecognized low blood sugars in people with Type 1 diabetes of more than five years’ duration.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are people with Type 1 diabetes for more than five years, very low C-peptide (<0.3 ng/mL), on insulin therapy, and with impaired hypoglycemia awareness or at least one episode of severe hypoglycemia in the past year who can comply with frequent glucose monitoring.

Probably not a fit

People with active systemic infections, recent cancer, positive viral serology (HBsAg, HCV, HIV), or significant residual insulin production (higher C-peptide) are excluded and are unlikely to benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 1/2 interventional trial enrolls participants with Type 1 diabetes for at least five years, very low C-peptide, and either impaired hypoglycemia awareness or recent severe hypoglycemia to receive allogeneic human E-islet 01. The protocol focuses on safety and tolerability while tracking effects on hypoglycemia frequency and metabolic markers such as mixed-meal stimulated C-peptide. Eligible participants must be on continuous insulin therapy and able to perform frequent self-blood glucose monitoring, and those with active systemic infections or recent malignancy are excluded. Follow-up visits and safety/efficacy assessments are conducted at the single study site in Shanghai.

Why it matters

Potential benefit: If successful, E-islet 01 could reduce episodes of severe hypoglycemia and improve glycemic stability and quality of life for people with long-standing Type 1 diabetes.

How similar studies have gone: Allogeneic islet transplantation and other cell-based beta-cell replacement approaches have reduced severe hypoglycemia in selected patients, but these therapies remain experimental and results have been variable.
