Phase 1 Interventional Xijing Hospital · NCT07339631

This trial tests whether oral sodium aescinate tablets can reduce pain and improve function in adults aged 18–65 with chronic low back pain lasting at least 12 weeks and a pain score above 4.

What this trial studies

This is a randomized, double-blind, placebo-controlled Phase 1 trial comparing oral sodium aescinate tablets to matched placebo in adults with non-specific chronic low back pain. Eligible participants (age 18–65, VAS >4, symptoms ≥12 weeks) are randomly assigned 1:1 and take 2 tablets twice daily for 6 weeks. Outcomes include pain intensity (VAS) at weeks 1, 3, and 6, disability scores (ODI), functional measures, and MRI measures of lumbar paraspinal muscle cross-sectional area and fat infiltration, with safety and adverse events monitored throughout. Follow-up visits occur at baseline, week 1, week 3, and week 6 for efficacy and safety assessments.

Who should consider this trial

Good fit: Adults 18–65 with non-specific chronic low back pain for at least 12 weeks and moderate to severe pain (VAS >4) who can take oral medication and attend in-person visits are ideal candidates.

Not a fit: People in an acute pain flare, those whose back pain is caused by infection, tumor, or other specific structural disease, patients outside the 18–65 age range, or those unable to attend visits are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, sodium aescinate could offer a new oral option to reduce pain and improve function and paraspinal muscle condition in people with chronic low back pain.

How similar studies have performed: There is limited clinical evidence for aescinate's anti-inflammatory effects, but oral sodium aescinate for chronic low back pain is relatively novel and not yet well established by prior trials.
