Site #:
Investigator #:
Phase 2
Subjects 100/10 Sites = 10 Subjects per Site
Primary Objective: Evaluate the effect of administering four doses of narcotic, (Doses A, B, C and D) of a Hydromorphone Skin Patch versus P (Placebo) in the treatment of moderate to severe Osteoarthritis Pain. (A is the Lowest & D the Highest dose).
AE’s were mild to moderate: HA, Nausea
Pt’s already on Opioids: R in a 2:2:1 ratio to: A, B or P
Pt’s Opioid Naïve: R in a 2:1 ratio to: either the lowest dose of the Study Drug, Dose A or Placebo
MS is the “escape” or rescue medication
All Pts will be required to remain at the randomized dose of study drug for the first week after which they will be allowed to escalate.
Dose escalations will be allowed once a week thereafter based on pain relief and use of rescue medication.
Pts will be allowed to escalate up to Dose D if required.
WOMAC: Western Ontario and McMaster University Index for disease-specific assessment of Hip or Knee OA
(Assesses the three dimensions of Pain, Disability and Joint Stiffness where 0 is Worst or most severe pain & 96 Best or least pain)
Diary: evaluate daily pain severity on a 4 point scale
IC
Age: 30-80 3 month h/o Symptomatic OA Hip or Knee with Lequesne severity index equal/greater than 9 @ screening requiring NSAID’s, Analgesics or Narcotics
WOMAC < 60 at Baseline Visit
All non-opioid Analgesics & NSAID’s must have been discontinued for 5 or more half-lives prior to study drug administration on day 1
If previously on Opioids, Pts must be taking only MS to control the pain, at the time of drug administration on day 1
EC
Any Skin Disorder
RA or Ankylosing Spondylitis
Neuropathic, Congenital or Metabolic Joint Diseases, FM
+ FH Drug or ETOH abuse
No systemic corticosteroids within 4 weeks study drug administration on Day 1
No intra-articular administration of corticosteroids within 8 weeks prior to study drug administration on Day 1
Must d/c the following drugs 5 or more half-lives prior to drug administration on Day 1:

Kellgren-Lawrence X-Ray Grading Scale

Osteoarthritis Severity Grades for Knee and Hip Joints
Adapted from the Council for International Organizations of Medical Sciences 1963

Subjects are required to have radiographic evidence of Grade 2-4 osteoarthritis of the Hip or Knee. The Kellgren scale used for assessing OA, described below, must be applied to a radiograph of the joint as follows: (Required position: Knee Standing + Hip Supine.)
Knee Joint (Standing Knee)
0 Normal
1 Doubtful narrowing of joint space and possible osteophyte lipping
2 Definite osteophytes and possible narrowing of joint space
3 Moderate multiple osteophytes, definite narrowing of joint space and some sclerosis and some sclerosis and possible deformity of bone ends
4 Large osteophytes, marked narrowing of joint space, severe sclerosis and definite deformity of bone ends
Hip Joint (Supine Hip)
0 Normal
1 Possible narrowing
2 Definite narrowing of joint space inferiorly, definite osteophytes and slight sclerosis
3 Marked narrowing of joint space, slight osteophytes, some sclerosis and cyst formation and deformity of femoral head and acetabulum
4 Gross loss of joint space with sclerosis and cysts, marked deformity of femoral head and acetabulum and large osteophytes
