About this study

Official title: A Long-Term Extension Study Evaluating the Safety and Efficacy of Lorecivivint in Subjects With Osteoarthritis of the Knee

Study OA-07 was a randomized, double-blind, placebo-controlled, Phase 3, multicenter, 2-year clinical trial that enrolled subjects from the recently completed Study OA-11 (NCT03928184).

The first 48 weeks of OA-07 the trial was placebo-controlled with subjects receiving the same randomized treatment received in OA-11. Investigators, research staff and subjects remained blinded to treatment allocation.

At Week 48, all subjects were administered LOR in the open-label portion of the trial.

Read the detailed description

At Visit 1E (on Day 1), upon completion of initial study procedures (e.g., informed consent, eligibility requirements, clinical evaluations including pregnancy testing [as applicable], baseline patient-reported outcome [PRO] assessments and safety data collection), subjects received a blinded IA injection of either LOR or PBO (as originally randomized in the parent [OA-11] study) into their target knee.

At Visit 3E (Week 48), upon completion of scheduled clinical, medical, safety and Patient-reported outcome (PRO) assessments, all subjects received an open-label injection of IA LOR into their target knee, such that previously PBO-treated subjects were effectively crossed over to the LOR treatment cohort.

Subjects were given the option to either receive a final injection of IA LOR into their target knee and complete both Visit 6E (Week 100) assessments and End-of-Study Visit assessments, or receive no injection and complete End-of-Study Visit assessments only. Subjects who had completed Visit 6E prior to the announcement of study closure were instructed to return to the clinic for End-of-Study Visit assessments.

Study OA-07's initial study design was to assess the safety and efficacy of additional treatment with LOR compared to PBO over one year and conclude at Visit 3E. The study was amended to become an open-label study at the Visit 3E that included an End-of-Study visit but without a specified time. The study was intended and described in the protocol to be run until such time as the Sponsor chose to close it. Study OA-07 was administratively closed at Visit 6E (Week 100), with no safety concerns, one year into the open-label study. For these reasons, Study OA-07 is considered a completed study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From OA-11-study Baseline Medial Joint Space Width (mJSW) in the Target Knee

    Change from OA-11-study baseline in mJSW measured in millimeters as documented by radiograph (X-ray) of the target knee. JSW measurements were provided by a blinded, central imaging vendor using landmark-based, computer-assisted proprietary methodology.

    Measured: OA-11-study baseline; Visit 3E (Week 48)

  2. Change From OA-07-study Baseline OA Pain in the Target Knee

    Change from OA-07-study baseline OA pain the target knee as assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Numeric Rating Scale (NRS 3.1) pain subscore (WOMAC Pain).

    The WOMAC is a widely-used, proprietary outcome measurement tool used by health professionals to evaluate the condition of subjects with OA of the knee and hip, including pain (5 questions), stiffness (2 questions), and physical functioning (17 questions) of the joints. Each question is measured on a scale from 0 (lowest pain/lowest stiffness/highest function) to 10 (highest pain/highest stiffness/lowest function).

    The WOMAC Pain subscore ranges from 0 [no pain] to 100 [pain as bad as it can be].

    Measured: OA-07-study baseline; Visit 2E (Week 24)

  3. Change From OA-07-study Baseline OA Function in the Target Knee

    Change from OA-07-study baseline OA function in the target knee as assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Numeric Rating Scale (NRS 3.1) physical functioning subscore (WOMAC Function).

    The WOMAC is a widely-used, proprietary outcome measurement tool used by health professionals to evaluate the condition of subjects with OA of the knee and hip, including pain (5 questions), stiffness (2 questions), and physical functioning (17 questions) of the joints. Each question is measured on a scale from 0 (lowest pain/lowest stiffness/highest function) to 10 (highest pain/highest stiffness/lowest function).

    The WOMAC Function subscore ranges from 0 [highest functional status] to 100 [most impaired functional status].

    Measured: OA-07-study baseline; Visit 2E (Week 24)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lorecivivint in people with Osteoarthritis, Knee, run by Biosplice Therapeutics, Inc. at 42 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 24 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 42 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Mar 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From OA-11-study Baseline Medial Joint Space Width (mJSW) in the Target Knee (time frame: OA-11-study baseline; Visit 3E (Week 48)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Mar 2026.
