Safety and Bone Health Study of SM04690 for the Treatment of Moderately to Severely Symptomatic Knee Osteoarthritis
United States101 participantsStarted 2018-11-28
Plain-language summary
The primary purpose of this phase 2, placebo-controlled, double-blind, parallel group study was to provide an initial safety evaluation of two intra-articular (IA) injections of SM04690 (each at the dose of 0.07mg per 2mL injection) approximately six months apart into the target knee of moderately to severely symptomatic osteoarthritis (OA) subjects. Subjects who completed this 52-week long study were invited to enter the extension phase for an additional 52 weeks of treatment.

Inclusion criteria
. Males and females between 40 and 80 years of age, inclusive, in general good health
. Ambulatory
. Diagnosis of femorotibial OA in the target knee by standard American College of Rheumatology (ACR) criteria at Screening Visit 1 (clinical AND radiographic criteria); OA of the knee is not to be secondary to any rheumatologic conditions (e.g., rheumatoid arthritis)
. Pain compatible with OA of the knee(s) for at least 26 weeks prior to Screening Visit 1
. Primary source of pain throughout the body is due to OA in the target knee
. Daily OA knee pain diary average NRS intensity score ≥ 4 and ≤ 8 in the target knee on the 11-point (0-10) NRS scale for the 7 days immediately preceding Day 1
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Change in Total BMD From Baseline in the Treated Knee Compared to Placebo by qCT
. Pain NRS scores recorded for the target knee on at least 4 out of the 7 days immediately preceding Day 1
. Daily OA knee pain diary average NRS intensity score \< 4 in the non-target knee on the 11-point (0-10) NRS scale for the 7 days immediately preceding Day 1
Exclusion criteria
. Pregnant and breastfeeding women, and women who are not post-menopausal (defined as 12 months with no menses without an alternative medical cause) or permanently surgically sterile (includes hysterectomy, bilateral salpingectomy, and bilateral oophorectomy) and have a positive or indeterminate pregnancy result at Screening Visit 2 or Day 1
. Women who are not post-menopausal or permanently surgically sterile, who are sexually active, and who are not willing to use birth control (as outlined in Section 5.3.1) during the study period
. Males who are sexually active and have a partner who is capable of becoming pregnant, neither of whom have had surgery to become sterilized or who are not using birth control as outlined in Section 5.3.1
. Body mass index (BMI) \> 35
. Partial or complete joint replacement in either knee
. Currently requires:
