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
- 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
- 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.
- 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)
- 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
