About this trial

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

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

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

The participant is able to read and understand the language and content of the study material and provide written Informed Consent.

Willing and able to comply with study requirements and instructions

A diagnosis of OA of the target knee based on American College of Rheumatology (ACR) clinical and radiographic criteria(31), with OA symptoms (as reported by the participant) that have been present for at least 3 months prior to screening

Radiological OA grade 2 or 3 of the target knee, using the Kellgren-Lawrence method as graded by a central reader on a Fixed-Flexion X-ray obtained during screening, or on a recent (within 6 months) X-ray which fulfills the protocol specifications for reading

Disqualifiers

Partial or complete joint replacement of either knee

Target knee surgery or arthroscopy within 1 year prior to screening

Diagnosis of OA resulting from trauma within the last 5 years

Pain of the contralateral knee exceeding that of the target knee at the baseline visit, as measured by the WOMAC pain subscale

Trial outcomes

Primary outcomes

1

The proportional change in body weight from baseline to endpoint

Time frame
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.

Time frame
183 Days

Secondary outcomes

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.

Time frame
183 Days
2

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

Time frame
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.

Time frame
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)
