Safety of a single transforaminal C-1101 injection versus saline for chronic sciatica
Official title: A Phase 1, Randomized, Double-Blind, Single Dose Escalation Study to Assess the Safety and Tolerability of Transforaminal Epidural Administration of C-1101 Versus Sterile Saline in Adults With Chronic Painful Lumbosacral Radiculopathy
Run by Consano Bio · NCT07264270 · Data updated 2026-11-12
This will test whether a single transforaminal epidural injection of C-1101 is safe and well tolerated compared with sterile saline in adults with chronic sciatica who have not improved with conservative care.

Is this trial a fit for you?
✓Likely a good fit
Adults with chronic lumbosacral radicular pain radiating to or below the knee who have not improved with conservative care and meet medical criteria (including BMI <35 and no bleeding risk, neuropathy, recent steroids, or prior back surgery) are the ideal candidates.
✕Probably not a fit
Patients with other significant painful conditions, peripheral neuropathies, active cancer, recent major cardiac events, those on anticoagulants or requiring transfusions, recent steroid/immunosuppressant use, or prior back surgery are excluded and therefore unlikely to benefit from participation.

What this trial studies
This Phase 1, randomized interventional trial compares a single transforaminal epidural dose of C-1101 to sterile saline with a primary focus on safety and tolerability. Eligible adults have lumbosacral radicular pain (sciatica) radiating at or below the knee and an inadequate response to conservative treatments, with body mass index under 35 kg/m2. Important exclusions include bleeding risk or anticoagulant use, peripheral neuropathies, recent major cardiac events, active malignancy, prior back surgery, recent systemic immunosuppression or steroids, and certain psychiatric diagnoses. The study is being conducted at Consano Bio research sites in Australia and uses a placebo-controlled design to isolate safety signals.
Why it matters
Potential benefit: If shown safe and tolerable, C-1101 could be developed further as a new injectable option to treat radicular leg pain from sciatica.
How similar studies have gone: Epidural injections (e.g., steroids, local anesthetics) have shown mixed short-term benefit for radicular pain in prior research, while C-1101 itself appears to be a novel agent without established clinical efficacy for this indication.
