Levicept Announces The Lancet Publication of LEVI-04 Phase II Clinical Trial Results, Showing Significant Reduction in Pain and Symptoms of Osteoarthritis
- Significant improvements in pain, function and patient global outcomes demonstrated
- LEVI-04 well tolerated and exhibits a favourable safety profile
Sandwich, UK – 30 March 2026 – Levicept Ltd, a biotechnology company focused on the development of LEVI-04, a first-in-class treatment for osteoarthritis (OA), today announces the publication in The Lancet of positive results of its Phase II study of LEVI-04 in patients with pain and disability due to OA of the knee [LANCET17736]1.
The trial was a multi-arm, International, multicentre, randomized, double-blind, placebo-controlled, Phase II study which enrolled 518 participants with pain and disability due to OA of the knee (ClinicalTrials.gov ID: NCT05618782).
Professor Philip Conaghan MBBS PhD, Director NIHR Leeds Biomedical Research Centre, Chief Investigator of the study and lead author of The Lancet publication said, “The potential benefits of this treatment for patients are very significant. Osteoarthritis impacts on all aspects of people’s lives and there are limited therapy options currently to manage the symptoms. This has left us and our patients with very few choices to relieve the discomfort caused by the condition.
“LEVI-04 as the first in a new line of therapies offers the possibility to be a game-changer, giving us better options to treat the pain faced by patients, and with further possibilities to unlock new treatments in the future. It also offers us as a chance to improve wellbeing, reduce the cost of support patients need from health services, and giving patients hope of being able to live more independently.”
LEVI-04 demonstrated significant differences to placebo for the WOMAC pain score primary endpoint for all doses. Additionally, significant improvements with LEVI-04 were observed across secondary endpoints, including patient-reported function, stiffness, and Patient Global Assessment. Responder analyses confirmed the clinical meaningfulness of the reductions in pain, with more than half the patients treated with LEVI-04 reporting a 50% reduction in pain, and more than a quarter reporting a 75% reduction in pain.
LEVI-04 was well tolerated with no observed safety concerns. Incident rates of treatment-emergent adverse events were similar in the active treatment and placebo groups. The incidence of joint pathologies was not increased, with a low number of events recorded across the treatment and placebo groups.
Headline results were first presented at ACR Convergence, 2024. Further data analysis shared at ACR Convergence, 2025 has shown that LEVI-04 had positive dose-dependent effects on the size and presence of bone marrow lesions compared to placebo, suggesting LEVI-04 may have disease modification properties in addition to the analgesic properties already reported.
Simon Westbrook, Founder and CSO and senior author of The Lancet publication said, “We are hugely proud to have had our study selected for publication in The Lancet. We believe LEVI-04 has a unique profile as a new treatment option for OA. As shown in The Lancet publication, LEVI-04 significantly reduces pain and symptoms of OA. Separately, we have also demonstrated potential to directly address the OA disease process. We believe it is the only molecule to have demonstrated both analgesia and the potential for disease modification in a clinical study in patients with OA.
“I would like to thank our investigators, all those involved in the study, and most importantly the participants. We now concentrate on further advancing the clinical development of LEVI-04 as new treatment options for millions of patients with OA in need worldwide.”
