2 Weekly Intra-articular Hyaluronan Knee Injections, Given 1 wk. Apart, of HYMOVIS Combined With Physical Exercise Program (PEP) Compared to PEP Alone, in Relatively Young, Active Population of Subjects With Patellofemoral Osteoarthritis (PFOA) and/or Tibiofemoral Osteoarthritis (TFOA)
Knee osteoarthritis (OA) is among the most common causes of musculoskeletal pain and disability. At present, there is no cure for OA. Therefore, the primary aims of therapy are to reduce pain, maintain or improve function and mobility, and prevent or slow the progression of adverse changes to the joint tissues, while keeping potential therapeutic toxicities to a minimum. Current treatment guidelines begin with non-pharmacologic modalities, such as patient education, weight loss, and physical therapy. Several exercise-based therapeutic approaches, such as aerobic exercise programs, range-of-motion exercises, and muscle-strengthening exercises are recommended and have shown clinical benefit in randomized, controlled clinical trials. However, non-pharmacologic approaches frequently provide insufficient pain relief and restoration of function and mobility, and pharmacologic modalities become necessary. Although simple analgesics such as acetaminophen provide relief for many OA subjects with mild to moderate pain, alternatives should be considered for subjects who fail to obtain adequate symptomatic relief with these measures. This post-market, single blind, multicenter, randomized, controlled clinical study is designed to enroll a relatively young, active population of subjects with patellofemoral osteoarthritis (PFOA) and/or tibiofemoral osteoarthritis (TFOA), and to compare responses to treatment with 2 weekly intra-articular (IA) hyaluronan (HA) injections, with each injection given 1 week apart, of HYMOVIS combined with a physical exercise program (PEP) to PEP alone. Because PEP or exercise programs may be considered the first line standard of care in OA knee pain, particularly in younger, active patients, the hypothesis of the study is that Hymovis combined with PEP program provides greater relief of pain associated with knee OA in the enrolled study subjects than with use of PEP alone. The study provides for subjects randomized to the PEP alone study group to cross over to HYMOVIS+PEP if improvement has not been achieved by the 3 month follow up visit. Subjects will be recruited over an 18 month period. The duration of the trial per center will be approximately 27 months. This includes the enrollment period of 6 months, the follow-up period at 3 and 6 months and the additional follow-up period for patients who crossed-over; they will be followed for an additional 6 months following the initial 3month follow-up. The trial will end when the last subject makes the last visit.
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
