About this study

Official title: A Double-blind, Placebo-controlled, Randomized Study to Evaluate the Efficacy and Safety of KBP-336 As an Adjunct to Diet and Exercise in Obese Individuals with Osteoarthritis of the Knee

The goal of this clinical trial is to learn if KBP-336 works to treat pain in osteoarthritis in individuals living with obesity. It will also learn about the effects on other parameters, such as quality of life and metabolism, as well as safety of KBP-336. The main questions it aims to answer are:

  • Does KBP-336 lower knee pain from osteoarthritis in individuals with obesity
  • Does KBP-336 lower bodyweight in the same population. Researchers will compare KBP-336 to a placebo (a look-alike substance that contains no drug) to see if KBP-336 works to pain and obesity
Read more

Participants will:

  • Take KBP-336 or a placebo every week for 6 months
  • Visit the clinic once every 2 weeks for checkups and tests
  • Keep a diary of their symptoms and the amount of medication they use in addition to KBP-336

What is being measured

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

  1. The proportional change in body weight from baseline to endpoint

    Measured: 183 Days

  2. The change in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scale from baseline to endpoint

    Higher scores indicate worse pain, stiffness, and functional limitations. The WOMAC measures five items for pain (score range 0-20), two for stiffness (score range 0-8), and 17 for functional limitation (score range 0-68). Following assessment the scores are normalized.

    Measured: 183 Days

Secondary outcomes (13)
  1. Change from baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) stiffness and function scales during the trial and at Day 183

    Higher scores indicate worse pain, stiffness, and functional limitations. The WOMAC measures five items for pain (score range 0-20), two for stiffness (score range 0-8), and 17 for functional limitation (score range 0-68). Following assessment the scores are normalized.

    Measured: 183 Days

  2. Proportion of subjects reaching ≥5, ≥10 or ≥15% weight loss from baseline at Day 183

    Measured: 183 Days

  3. Proportion of subjects reaching ≥30 and ≥50% reduction in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scale from baseline at Day 183

    Higher scores indicate worse pain, stiffness, and functional limitations. The WOMAC measures five items for pain (score range 0-20), two for stiffness (score range 0-8), and 17 for functional limitation (score range 0-68). Following assessment the scores are normalized.

    Measured: 183 Days

  4. Change from baseline in Assessment of Quality of Life 8 Dimensions (AQol 8D) at Day 183

    The AQoL-8D consists of eight dimensions measured by 35 items with four to six levels each. Five out of eight dimensions assess the psychosocial domains of health: happiness, coping, self-worth, relationships, and mental health. The scale if from 0 - 1 and is calculated using (https://www.aqol.com.au/index.php/scoring-algorithms)

    Measured: 183 Days

  5. Change from baseline in Assessment of Quality of Life 8 Dimensions (AQol 8D) subscore Independent living at Day 183

    The AQoL-8D consists of eight dimensions measured by 35 items with four to six levels each. Five out of eight dimensions assess the psychosocial domains of health: happiness, coping, self-worth, relationships, and mental health. The scale if from 0 - 1 and is calculated using (https://www.aqol.com.au/index.php/scoring-algorithms)

    Measured: 183 Days

  6. Change from baseline in the weekly average of daily pain using the Numerical Rating Scale (NRS) during the trial, and at Day 183

    The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable").

    Measured: 183 Days

  7. Area under the curve from baseline in the weekly average of daily pain using the Numerical Rating Scale (NRS) to Day 183

    The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable").

    Measured: 183 Days

  8. Change from baseline to Day 183 in waist-to-hip ratio

    Measured: 183 Days

  9. Change from baseline in whole body composition by DXA at Day 183

    Measured: 183 Days

  10. Change from baseline in bone mineral density of the lumber spine, femoral head, and total hip by DXA at Day 183

    Measured: 183 Days

  11. Change from baseline in Patient Global Assessment at Day 183

    Measured: 183 Days

  12. Outcome Measures in Rheumatology (OMERACT) - Osteoarthritis Research Society International (OARSI) responder rates at Day 183

    Measured: 183 Days

  13. Average weekly days using rescue medication

    Measured: 183 Days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing KBP-336 in people with Osteoarthritis in the Knee and Obesity, run by KeyBioscience AG at 20 sites in 6 countries.

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 10 inclusion and 32 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: looking for participants now, as of the sponsor's last update on 19 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in Czechia, Poland, Denmark, Moldova, Romania and 1 more country. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact KeyBioscience AG Program Director, PhD (+41 795207086, rocco@keybioscience.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The proportional change in body weight from baseline to endpoint (time frame: 183 Days). The study lists 2 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 19 Feb 2025.
