Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the durability of efficacy and long-term safety of intramuscular administration of Engensis or Placebo that was administered in the double-blind, randomized, VMDN-003-2 Placebo-controlled Phase 3 Study.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this 6-month extension study (VMDN-003-2b) is to evaluate the durability of efficacy and long-term safety of intramuscular administration of Engensis or Placebo that was administered in the double-blind, randomized, VMDN-003-2 Placebo-controlled Phase 3 Study. No treatments will be administered in this VMDN-003-2b extension study. The combined overall duration of the VMDN-003-2 and VMDN-003-2b studies will be 12 months.

Participants will be enrolled in the VMDN-003-2b study at completion of the Day 180 Visit of Study VMDN-003-2. Participants will continue to be identified by the same Participant number and the same treatment group (Engensis or Placebo) assigned by randomization in Study VMDN-003-2. No study drug or treatment will be administered in this VMDN-003-2b extension study. The double-blind treatment assignment from the prior study will be maintained for Investigators and Participants during this extension study.

This extension study will assess the durability of efficacy and long-term safety of Engensis compared to Placebo as measured by changes in Average Daily Pain Score of the full Brief Pain Inventory for Diabetic Peripheral Neuropathy, Bedside sensory testing, physical examinations, laboratory assessments, vital signs, treatment-emergent adverse events, treatment-emergent serious adverse events, and adverse events of special interest.
