What this trial studies

This is a randomized, double-blind, placebo-controlled phase III trial comparing a single treatment of SL1002 to normal saline for knee pain from mild to moderate osteoarthritis (Kellgren-Lawrence grade 2–3). Adults aged 40 and older with chronic knee pain who meet screening criteria, including a positive diagnostic nerve block response, may be enrolled and continue stable baseline analgesics. Participants are randomized to receive either SL1002 or placebo and are followed for safety and pain outcomes after the single dose. The study is conducted at multiple clinical research sites in the United States.

Who should consider this trial

Good fit: Ideal candidates are adults aged 40 or older with chronic knee pain from mild to moderate osteoarthritis (KL grade 2–3), meeting BMI limits, responsive to a diagnostic nerve block, and able to attend study visits at a participating site.

Not a fit: Patients with non-osteoarthritis inflammatory arthritis, severe (KL grade 4) disease, significant hepatic or renal impairment, certain medication conflicts, or relevant allergies or recent substance abuse are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, SL1002 could offer meaningful single-dose pain relief for knee osteoarthritis and reduce reliance on daily systemic pain medications.

How similar studies have performed: Early-phase trials of SL1002 or similar single-dose local or nerve-targeted therapies have shown mixed but sometimes promising signals, so a phase III trial is being done to confirm benefit.
