Can a knee injection regrow cartilage? new trial tests LRX712
NCT ID NCT04097379
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tested an experimental drug called LRX712, given as injections into the knee, to see if it can help regrow cartilage in people with mild to moderate knee osteoarthritis. 45 participants received either the drug or a placebo over 8 weeks. The main goal was to measure changes in cartilage volume using advanced MRI scans.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- LRX712 (injected into the knee joint)
- What this could lead to
- If it works, this could point toward a treatment that repairs cartilage and slows knee osteoarthritis.
- What could go wrong
- This is a small, early-phase trial with only 45 people. The drug may not work better than placebo, and long-term safety is unknown.

Inclusion Criteria: Written informed consent must be obtained before any assessment is performed. To be eligible for inclusion in this study patients must meet all of the following criteria: * Patient must have a BMI between 18 -35 kg/m2 * Patient must have symptomatic knee osteoarthritis predominantly in one knee (index knee) * Patient must have knee osteoarthritis (Kellgren-Lawrence grade 2 or 3) in the index knee, as confirmed by radiography * Patient must have radiographic confirmation of a medial joint space width of 1.5 to 3.5 mm for females, or 2 to 4 mm for males within the medial tibio-femoral compartment of the index knee. Exclusion Criteria: Subjects meeting any of the following criteria are not eligible for inclusion in this study: * Patient has a known autoimmune disease, inflammatory or chronic arthropathy other than OA. * Patient had partial or complete joint replacement in one or both knees. * Patient has symptomatic, isolated patello-femoral pain in the index knee as per the Investigator's examination. * Pregnant or nursing (lactating) women. * Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant. * Previous use of LRX712 or use of other investigational drugs at the time of enrollment, or within 5 half-lives of enrollment, or within 30 days, whichever is longer; or longer if required by local regulations. * Patient has malalignment (valgus- or varus-deformity) ≥ 7.5° in the index knee as per anatomic PA axis measured by weight-bearing short knee radiography. * History of significant cardiac conduction/electrophysiological disorder, e.g. familial long QT syndrome or known family history of Torsades de Pointes or prolonged QT syndrome or QTcF ≥ 450 msec (Fridericia Correction) for males and ≥ 460 msec for females at screening or baseline (by local 12-lead digitized ECG reading). * Signs or symptoms, in the judgment of the investigator, of a clinically significant systemic viral, bacterial or fungal infection within 30 days prior to screening. Other protocol-defined inclusion/exclusion criteria may apply.
