Study of OPF-310 for Type 1 Diabetes Mellitus

This study is testing a new treatment called OPF-310, which uses porcine (pig) pancreatic cells, for people with unstable Type 1 Diabetes Mellitus. The main goal is to see how safe and effective OPF-310 is, and to figure out the best dose for future studies. You might be able to join if you are 35 to 65 years old, have had Type 1 diabetes for at least 5 years, and have experienced severe low blood sugar (hypoglycemia) multiple times in the past year, even with a closed-loop insulin system. The study will measure how many participants reach a specific treatment goal one year after receiving the transplant. This is a "first-in-human" study, meaning it's the first time this treatment is being given to people.

Study design
This is an interventional study, meaning participants will receive a specific treatment. It plans to enroll 13 participants to assess the safety and effectiveness of OPF-310.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for one year after the transplant to measure the main treatment goal.

  • Percentage of Subjects Reaching the Efficacy GoalOne year after transplant

    A successful primary endpoint was defined as achieve both an HbA1c \< 7 % and a reduction of at least 0.5% from baseline, and absence of a Level 3 (severe) hypoglycemic episode from 12 weeks to 52 weeks post-transplant.
