Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a multi-center, randomized, double-blind, and placebo-controlled phase 3 study evaluating the safety and efficacy of HP-5000 in subjects with OA pain of the knees. The study will consist of up to a 28-day Screening Phase that will include a Washout Period of current prescription and over the counter (OTC) analgesics; a 12-week Double-blind Treatment Phase, and a 1-week safety Follow-up Phase.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Male or female aged 40 to 85 years with a clinical diagnosis of OA of the target knee according to the American College of Rheumatology criteria.
  • Has an X-ray of the target knee, taken no more than 1 year before Baseline, showing evidence of OA.
  • Has pain of OA in the designated/target study knee.

Exclusion Criteria:

  • Body mass index (BMI) > 40.
  • Any subject who did not follow the restriction of prohibited therapies during Washout period.
  • Arthritis of the target knee that is not caused by OA but caused by diseases such as rheumatoid arthritis, gout, psoriasis, syphilitic arthropathy, ochronosis, metabolic or other primary bone disease, or acute traumatic injury.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline to Week 12 in WOMAC Pain Score (Intent-to-treat Set)
Time Frame: Baseline and 12-week
To evaluate efficacy of HP-5000 patch treatment compared with HP-5000 placebo patch treatment of Osteoarthritis of the knee as evaluated by change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score from baseline to week 12. WOMAC pain score is a scale that evaluate five items including walking, stair climbing, nocturnal, rest and weight bearing. Each item is rated on a scale of 0 to 4, with 0 being no difficulty and 4 being extremely difficulty. The total score is the sum of five items. The total score ranges from 0 to 20 with a low score considered a better outcome and a high score considered a worse outcome.
Baseline and 12-week

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline to Week 12 in WOMAC Stiffness Score
Time Frame: 12 weeks
To evaluate efficacy of HP-5000 patch treatment compared with HP-5000 placebo patch treatment of Osteoarthritis of the knee as evaluated by change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score from baseline to week 12. WOMAC pain score is a scale that evaluate five items including walking, stair climbing, nocturnal, rest and weight bearing. Each item is rated on a scale of 0 to 4, with 0 being no difficulty and 4 being extremely difficulty. The total score is the sum of five items. The total score ranges from 0 to 20 with a low score considered a better outcome and a high score considered a worse outcome.
12 weeks
WOMAC Physical Function Change From Baseline at Week 12

To evaluate efficacy of HP-5000 patch treatment compared with HP-5000 placebo patch treatment of Osteoarthritis of the knee as evaluated by change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score from baseline to week 12. WOMAC pain score is a scale that evaluate five items including walking, stair climbing, nocturnal, rest and weight bearing. Each item is rated on a scale of 0 to 4, with 0 being no difficulty and 4 being extremely difficulty. The total score is the sum of five items.
