E.3 | Principal inclusion criteria |
[1] Are male or female patients with OA, as determined by medical history and physical examination. Males and females with stable medical problems that,
in the investigator’s opinion, will not significantly alter the disposition of the
drug, will not place the patient at increased risk by participating in the study,
and will not interfere with interpretation of the data.
a Male patients: agree to use a reliable method of birth control during the
study and for 3 months following the last dose of the investigational
product.
b Female patients: women not of child-bearing potential due to surgical
sterilization (at least 6 weeks post surgical bilateral oophorectomy with
or without hysterectomy or tubal ligation) confirmed by medical history,
or menopause.
Postmenopausal women: Women with an intact uterus are deemed
postmenopausal if they have had cessation of menses for at least 1 year with
follicle-stimulating hormone (FSH) and oestradiol values compatible with
postmenopausal status, age ≥45 years old, and not taking oral contraceptives
within the last year.

presented in the Inclusion Disease Criteria, below.
[4] Blood pressure and pulse rate in supine and standing positions, within normal
reference ranges for the population and investigator CRU, or results with
acceptable deviations that are judged to be not clinically significant by the
investigator.
[5] Have clinical laboratory test results within normal reference range for the
population or investigator CRU, or results with acceptable deviations that are
judged to be not clinically significant by the investigator.
[6] Have venous access sufficient to allow for blood sampling as per the
protocol.

study and willing to abide by the study restrictions
[10] Have a unilateral or bilateral OA of the knee diagnosed according to the
American College of Rheumatology (ACR) criteria based on clinical and
radiographic evidence (Altman et al. 1986). The clinical diagnosis of OA
will be confirmed by the ACR clinical and radiographic criteria for
classification of idiopathic OA of the knee based upon the following criteria:
a. Knee pain for at least 14 days per month for the 3 months before
screening visit.
b. Osteophytes (with radiographic evidence).
c. At least 1 of the following 3 conditions: Age >50, or Morning stiffness
<30 minutes, or Crepitus.
d. If the patient has had an X-ray of the index joint within the last year
which can confirm the diagnosis it may be used, otherwise a new
anterior-posterior view x-ray should be obtained and reviewed by
Principal Investigator or his delegates to verify that the patient meets the
disease diagnostic criteria.
[11] Have a Kellgren and Lawrence grade of I, II, III or IV.
[12] Have a mean score of at least 4 (moderate) and less than or equal to 8
(moderate-severe) on the 24-hour average pain score (0-10) (question 1) in
the patient e-diary from Visit 2 to Visit 3 for the knee joint during walking.
[13] Discontinued use of all analgesic medications (including over-the-counter
[OTC] analgesics/ Non-Steroidal Anti-Inflammatory Drug (NSAID) at least 2
weeks prior to randomization (patients are allowed limited use of analgesic
medications). |
|
E.4 | Principal exclusion criteria |
Have an abnormality in the 12-lead ECG at screening that, in the opinion of
the investigator, increases the risks associated with participation in the study.
In addition, patients with following findings will be excluded:
- Confirmed Bazett’s corrected QT (QTcB) interval > 450 msec for men and
> 470 msec for women in 2 of 3 ECGs; additional ECGs may be performed if
required,

first degree atrio-ventricular block,
- Irregular rhythms other than sinus arrhythmia or occasional, rare
supraventricular or rare ventricular ectopic beats,
- History of unexplained syncope,
- Family history of unexplained sudden death or sudden death due to long QT
syndrome,
- T-wave configurations are not of sufficient quality for assessing QT interval
determination, as assessed by the investigator.
Have current or previous (within the past year) Axis 1 diagnosis of major
depressive disorder, mania, bipolar disorder, psychosis, dysthymia,
generalized anxiety disorder, alcohol or eating disorders according to
“Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Text
Revision” (DSM-IV; APA 2000) criteria, as determined by the investigator
and confirmed by the Mini-International Neuropsychiatric Interview (MINI,
Sheehan et al. 1998)).

inflammatory joint disease, articular fracture, major dysplasias or congenital
abnormality, ochronosis, acromegaly, hemochromatosis, Wilson's disease,

≥2000 mm3 that is indicative of a diagnosis other than OA.
Have a confounding painful condition that may interfere with assessment of
the index joint, i.e., knee. (Knee pain should be the predominant pain. Mild
OA of the hands is allowed, for instance).
Have any other musculoskeletal or arthritic condition that may affect the
interpretation of clinical efficacy and/or safety data or otherwise
contraindicates participation in this clinical study (i.e., currently symptomatic
fractures or any concurrent rheumatic disease such as but not limited to

Have initiated or have changed to an established physiotherapy program
within 2 weeks prior to Visit 3 or during the study period. An established
physiotherapy program may be continued throughout the study period if
