Lorecivivint promising treatment option for knee osteoarthritis, interim findings from trial reveal
USA: Repeated injections of the lorecivivint (LOR) in knee osteoarthritis patients may slow the decline of medial joint space width, according to interim findings from a long-term extension trial released by Biosplice.
"We believe these unique data highlight lorecivivint's promise to potentially provide structural benefit to the millions of patients suffering from osteoarthritis," commented Biosplice Chief Medical Officer, Yusuf Yazici, MD. "These latest interim results from OA-07 build upon our robust body of existing evidence, suggesting that repeat injections of LOR could provide patients and physicians with both structure-modifying and symptomatic benefits. We recently initiated our phase 3 OA-21 clinical trial and are enrolling subjects. We are excited to continue investigating LOR as a treatment option for knee OA."
OA-07 is a long-term extension trial, which enrolled patients who completed OA-11, a previous 12-month study. The primary efficacy objective of OA-07 is to measure the disease-modifying potential of lorecivivint over multiple years and injections. During the first year of the OA-07 study, patients and investigators remained blinded. Patients received injections of LOR annually, allowing Biosplice to capture both long-term and repeat-injection data for safety, efficacy, and mJSW.
Previously presented at the American Conference of Rheumatology Annual Meeting in November 2022, data for the first year of OA-07 show clinically significant improvement in mJSW relative to placebo, with an effect size of 0.13 mm in KL2 subjects. Moreover, OA-07 data demonstrate a significant improvement in WOMAC Pain and robust trends in Pain NRS (daily pain score) as well as WOMAC function in all subjects.
In the second year of the OA-07 trial, placebo subjects crossed-over to receiving LOR, although all subjects remain blinded as to whether they had previously received LOR or placebo. In subjects who have completed their second annual visit and who previously received LOR in OA-11 and OA-07, there continues to be an increase in their mJSW versus baseline. These subjects have now received three injections of LOR over three years.
Among those subjects who have completed their second annual OA-07 visit and who previously had received placebo, the introduction of LOR appears to have arrested their decline in mJSW.
Please see graphic below for the interim data generated to date.
Consistent with the clinical program to date, LOR continued to appear safe and well-tolerated in the recently completed studies, with no safety signals with repeat injections.
The OA-21 phase 3 clinical trial is designed as a 16-week study with a primary endpoint of Pain NRS at 12 weeks. This study will further evaluate the impact of LOR on knee osteoarthritis pain and function and has been designed to enroll the less structurally damaged patient population that has shown consistent responses across Biosplice's phase 2 and phase 3 clinical trials.
