Brief summary
The purpose of the study is to evaluate the efficacy and safety of actovegin in participants with peripheral arterial disease (PAD) Fontaine Stage IIB.
Detailed description
The study will enroll approximately 366 participants. Participants will be randomly assigned to one of the two treatment groups in 1:1 ratio: 1. Actovegin 2. Placebo (dummy inactive substance) - this is a tablet/intravenous infusion that looks like the study drug but has no active ingredient All participants will be asked to take intravenous infusion for 2 weeks followed by oral tablets for 10 weeks. This multi-center trial will be conducted Russia, Georgia, and Kazakhstan. The overall time to participate in this study is 25 to 26 weeks. Participants will make multiple visits to the clinic, and 12 weeks after last dose of study drug for a follow-up assessment.
Interventions
Actovegin intravenous infusion and tablets.
Actovegin placebo-matching intravenous infusion and tablets.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percent Change From Baseline in Initial Claudication Distance (ICD) at Week 12 | Baseline up to Week 12 | ICD was the distance walked at the onset of claudication pain or pain-free walking distance. ICD was assessed using treadmill testing. A fixed load treadmill test was carried out at 3.0 kilometer per hour (km/h) with a 10 percent (%) grade. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percent Change From Baseline in ICD at Weeks 2 and 24 | Baseline up to Weeks 2 and 24 | ICD was the distance walked at the onset of claudication pain or pain-free walking distance. ICD was assessed using treadmill testing. A fixed load treadmill test was carried out at 3.0 km/h with a 10% grade. |
| Absolute Change From Baseline in Absolute Claudication Distance (ACD) at Weeks 2, 12 and 24 | Baseline, Weeks 2, 12 and 24 | ACD was the distance at which claudication pain becomes so severe that the participant was forced to stop, also known as maximal walking distance. ACD was assessed using treadmill testing. A fixed load treadmill test was carried out at 3.0 km/h with a 10% grade. The investigator will record the distance from walking start to the point where the participant is unable to walk anymore. |
| Percentage of Participants With Rest Pain at Weeks 12 and 24 | Weeks 12 and 24 | Rest pain was defined as a continuous burning pain, that begins, or is aggravated, after reclining or elevating the limb and is relieved by sitting or standing. |
| Percentage of Participants With Revascularization Procedures at Week 24 | Week 24 | Revascularization was defined by a Thrombolysis in Myocardial Infarction (TIMI) score of 2 or 3 following use of the Penumbra System. TIMI scores were used to describe blood flow at the treated vessel with 0 designating no flow and 3 for normal flow. |
| Change From Baseline in 36-Item Short Form Survey (SF-36) at Weeks 12 and 24 | Baseline, Weeks 12 and 24 | The SF-36 was a questionnaire that evaluated a participant's health related quality of life. SF-36 included 36 questions related to 8 health dimensions: physical functioning, role-physical (role limitations due to physical health problems), bodily pain, general health, vitality (energy/fatigue), social functioning, role-emotional (role limitations due to emotional problems), and mental health. Based on these 4 scales (physical functioning, role-physical, bodily pain, general health), the physical health score was generated which ranges between 0 and 100, with higher scores indicating a better quality of life. Based on these 4 scales (vitality, social functioning, role-emotional, and mental health), the mental health score was generated which ranges between 0 and 100, with higher scores indicating a better quality of life. |

Outcome results
Percent Change From Baseline in Initial Claudication Distance (ICD) at Week 12
ICD was the distance walked at the onset of claudication pain or pain-free walking distance. ICD was assessed using treadmill testing. A fixed load treadmill test was carried out at 3.0 kilometer per hour (km/h) with a 10 percent (%) grade.
