Study Details

Study Description

Brief Summary

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

Condition or Disease Intervention/Treatment Phase
  • Biological: Engensis
  • Other: Placebo
Phase 3

Detailed Description

The purpose of this 6-month extension study (VMDN-003-2b) is to evaluate the durability of efficacy and long-term safety of intramuscular (IM) 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 (ADPS) of the full Brief Pain Inventory for Diabetic Peripheral Neuropathy (BPI-DPN), Bedside Sensory Testing (BST), physical examinations, laboratory assessments, vital signs, treatment-emergent adverse events (TEAEs), treatment-emergent serious adverse events (TESAEs), and adverse events of special interest (AESIs).

Outcome Measures

Primary Outcome Measures

  1. To evaluate the efficacy of IM administration of Engensis on pain in Participants with painful DPN in the feet and lower legs as compared to Placebo [From the 7 days prior to the Day 0 Visit (Study VMDN-003-2) to 7 days prior to the Day 365 Visit]

    Change in the means of the Average Daily Pain Scores (ADPSs) from the full Brief Pain Inventory for Diabetic Peripheral Neuropathy (BPI-DPN). Maximum score = 10, minimum score = 1, higher score is a worse outcome.

Secondary Outcome Measures

  1. To evaluate the efficacy of IM administration of Engensis on the worst pain in Participants with painful DPN in the feet and lower legs as compared to Placebo [From the 7 days prior to the Day 0 Visit (Study VMDN-003-2) to the 7 days prior to the Day 365 Visit]

    Change in the means of the Worst Pain scores from the full Brief Pain Inventory for Diabetic Peripheral Neuropathy (BPI-DPN). Maximum score = 10, minimum score = 1, higher score is a worse outcome.

  2. To evaluate the efficacy of IM administration of Engensis on reducing pain in Participants with painful DPN in the feet and lower legs [From the 7 days prior to the Day 0 Visit (Study VMDN-003-2) to the 7 days prior to the Day 270 Visit and the 7 days prior to the Day 365 Visit]

    Proportion of Responders (>=50% reduction in the ADPSs from the full BPI-DPN)

  3. To evaluate the safety of IM administration of Engensis in Participants with painful DPN in the feet and lower legs [Day 0 to Day 365]

    Incidence of treatment-emergent adverse events (TEAEs), treatment-emergent serious adverse events (TESAEs), and clinically significant laboratory values
