About this trial

The goal of this clinical trial is to learn if adding a Traditional Chinese Medicine formula, Bu Yang Huanwu Decoction (specifically the capsule form called Hua Yu Wan Capsule), to standard treatment can help prevent leg pain at rest or foot ulcers in people with diabetic lower extremity vascular disease. The main questions it aims to answer are:

Does adding Hua Yu Wan Capsule to standard treatment lower the chance of developing leg pain at rest or foot ulcers after one year, compared to standard treatment alone?

Is the treatment combination safe for participants?

Researchers will compare two groups:

Group 1 (Experimental): Standard treatment (including aspirin, and medicines for blood sugar and cholesterol control) plus Hua Yu Wan Capsule.

Group 2 (Control): Standard treatment alone.

Participants in this study will:

Be adults aged 18 to 70 years with diabetes and early to moderate lower extremity vascular disease (confirmed by tests like the Ankle-Brachial Index or ABI).

Be randomly assigned to one of the two treatment groups.

Take their assigned treatment for 6 months.

Attend clinic visits at 1, 3 and 6 months during treatment, and again at 6 and 12 months after treatment ends for check-ups and tests.

Trial outcomes

Primary outcomes

1

Incidence of new-onset ischemic rest pain or foot ulcer at 12 months of treatment.

Ischemic Rest Pain: Persistent pain in the toes/forefoot at rest, typically nocturnal, worsened by elevation, relieved by dependency, often with pallor/coldness. Foot Ulcer: Ischemic skin breakdown/tissue necrosis in pressure areas (toes, heel, sole), with well-defined edges, dry/necrotic base, poor perfusion, and absence of significant inflammation. Assessment Method: Clinical evaluation by investigator at each scheduled visit. Confirmed by physical examination and documented photographically if applicable.

Time frame
From enrollment to the end of treatment at 12 months

Secondary outcomes

1

Number of participants with investigator-confirmed new-onset ischemic rest pain or clinically confirmed ischemic foot ulcer at 12 months

Composite primary outcome defined as the number of participants who develop either: (1) new-onset ischemic rest pain confirmed by investigator clinical assessment, or (2) ischemic foot ulcer confirmed by physical examination with photographic documentation when applicable, by Month 12.

Time frame
From enrollment to the end of treatment at 12 months
2

Number of participants with major adverse cardiovascular and cerebrovascular events (MACCE)

MACCE is defined as cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke.

Time frame

3

Number of participants hospitalized during the study

Number of participants who require inpatient hospitalization for any cause during the study period, as confirmed by hospital admission records or investigator documentation.

Time frame
From enrollment to the end of treatment at 12 months
4

Number of participants who die during the study

Number of participants who die from any cause during the study period, as confirmed by medical records, death certificates, hospital documentation, or investigator follow-up. Each participant will be counted once.
