What this trial studies

This Phase 3 clinical trial is designed to assess the efficacy and safety of HCP1004 in patients suffering from chronic low-back pain. It is a randomized, double-blind, active-controlled study that compares HCP1004 to RLD2401, focusing on patients with chronic low-back pain lasting at least three months. The study aims to determine whether HCP1004 is non-inferior to the comparator in terms of pain relief and safety. Participants will be monitored for their pain levels and any adverse effects throughout the trial.

Who should consider this trial

Good fit: Ideal candidates are adults aged 19 and older with chronic low-back pain lasting at least three months and a need for daily NSAID therapy.

Not a fit: Patients with serious underlying conditions causing low-back pain or recent trauma may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide significant pain relief for patients suffering from chronic low-back pain.

How similar studies have performed: Other studies have shown promise in treating chronic low-back pain with similar approaches, but the specific efficacy of HCP1004 remains to be established.
