Type	Measure	Description	Time frame	Safety issue
Other	Change From A4091026 (NCT00863772) Baseline in 5 Nerve Conduction Tests, Normal Deviate (5NC [nd]) Score at Week 24	5NC (nd) score included five NCS attributes: peroneal MNDL, CMAP, MNCV; tibial MNDL; sural SNAP. Values of attributes scored as percentiles (calculated from distribution of normal values corresponding to participant's baseline demographic characteristics), then expressed as nd score based on standard normal distribution. For CMAP, MNCV, SNAP: score <0 indicated worse and >0 indicated better response; for peroneal,tibial MNDL: score >0 indicated worse and <0 indicated better response, as compared to normal matched population. For CMAP, MNCV, SNAP: score change <0 indicated worsening and >0 indicated improvement; for peroneal,tibial MNDL: score change >0 indicated worsening and <0 indicated improvement, as compared to baseline. Total score calculated as sum of each NCS attribute. Total score >0 indicated worse and <0 indicated better response as compared to normal matched population. Total score change >0 indicated worsening and <0 indicated improvement as compared to baseline.	A4091026: Baseline, A4091040: Week 24
Other	Change From A4091026 (NCT00863772) Baseline in Heart Rate-Deep Breathing, Normal Deviate (HRdb, [nd]) Score at Week 24	HRdb test was used to evaluate the effect of treatment on autonomic function. Participant took a series of 8 deep breaths and average heart rate difference was measured and compared to normative data. R-R (time between two consecutive R waves in the electrocardiogram) response to deep breathing was reported as normal deviates. Score <0 indicated worse response and >0 indicated better response as compared to normal matched population. Score change <0 indicated worsening and >0 indicated improvement as compared to baseline. 2 neurological visits (NVs) were conducted both at baseline and Week 24. Measurements were collected twice and highest nd score was selected at each NV. Mean of the selected measurements was calculated to obtain Baseline and Week 24 values.	A4091026: Baseline, A4091040: Week 24
Other	Change From A4091026 (NCT00863772) Baseline in Intraepidermal Nerve Fiber Density (IENF) at Week 24	IENF density was quantified in 3 millimeter (mm) immunostained (PGP 9.5 immunohistochemical staining) skin punch biopsies taken from the distal end of the leg, 10 centimeter (cm) above the lateral malleolus, within the territory of the sural nerve, containing epidermis and superficial dermis to evaluate amount of small diameter nerve fibers. Skin biopsies were taken from normal appearing skin and skin having local scar, signs of trauma, ulceration, or active dermatologic process were avoided.	A4091026: Baseline, A4091040: Week 24
Other	Change From A4091026 (NCT00863772) Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Domain Scores at Week 8, 16, 24 and 32	WOMAC Index: self-administered, disease-specific 24-item questionnaire which assesses clinically important, participant-relevant symptoms for pain (5 items), stiffness (2 items), and physical function (17 items) in participants with osteoarthritis of the index hip or index knee. Each question was assessed on Numeric Rating Scale (NRS) as 0(none) to 10(extreme).Total possible domain score was calculated as the mean of the score for each domain questions. Score range:0-10,high scores=high pain/stiffness/difficulty in physical activity.	A4091026: Baseline, A4091040: Week 8, 16, 24, 32
Other	Change From A4091026 (NCT00863772) Baseline in Patient's Global Assessment (PGA) of Osteoarthritis at Week 8, 16, 24 and 32	PGA: Participants answered the following question: "Considering all the ways your osteoarthritis in your knee or hip affects you, how are you doing today?" Participants rated their condition using a 5-point Likert scale. Score range: 1 to 5. 1: Very Good (asymptomatic and no limitation of normal activities); 2: Good (mild symptoms and no limitation of normal activities); 3: Fair (moderate symptoms and limitation of some normal activites); 4: Poor (severe symptoms and inability to carry out most normal activities); 5: Very Poor (very severe symptoms which are intolerable and inability to carry out all normal activities).

Other	Percentage of Participants With Outcome Measures in Rheumatology - Osteoarthritis Research Society International (OMERACT-OARSI) Response	OMERACT-OARSI response: >=50 percent (%) improvement from A4091026 (NCT00863772) baseline and absolute change from A4091026 (NCT00863772) baseline of >=2 units at week of interest in WOMAC pain or physical function subscales, or at least 2 of the following 3 being true: >=20% improvement from A4091026 (NCT00863772) baseline and absolute change from A4091026 (NCT00863772) baseline of >=1 unit at week of interest in 1) WOMAC pain subscale, 2) WOMAC physical function subscale, 3) PGA of osteoarthritis (score: 1-5, higher score=more affected). WOMAC pain, physical function subscales assess amount of pain/difficulty experienced (score: 0-10, higher score=higher pain/difficulty).	Week 8, 16, 24
Other	Change From A4091026 (NCT00863772) Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Average Score at Week 8, 16 and 24	WOMAC: self-administered, disease-specific 24-item questionnaire which assesses clinically important, participant-relevant symptoms for pain (5 items), stiffness (2 items) and physical function (17 items) in participants with osteoarthritis of knee or hip. WOMAC average score is the mean of WOMAC pain, physical function and stiffness subscale scores and ranges from 0 to 10, where higher score indicates worse response. Change from baseline <0 indicates an improvement.	A4091026: Baseline, A4091040: Week 8, 16, 24
Other	Percentage of Participants With at Least 30%, 50%, 70% and 90% Reduction From A4091026 (NCT00863772) Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale Score	The WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis in the index joint (knee or hip) during the past 48 hours. It is calculated as the mean of the scores from the 5 individual questions scored on a numerical rating scale (NRS) of 0 to 10, where higher scores indicate higher pain. Total score range for WOMAC pain subscale score is 0 to 10, where higher scores indicate higher pain.	Week 8, 16, 24, 32
Other	Percentage of Participants With Improvement of At Least 2 Points From A4091026 (NCT00863772) Baseline in Patient's Global Assessment (PGA) of Osteoarthritis	PGA: Participants answered the following question: "Considering all the ways your osteoarthritis in your knee or hip affects you, how are you doing today?" Participants rated their condition using a 5-point Likert scale. Score range: 1 to 5. 1: Very Good (asymptomatic and no limitation of normal activities); 2: Good (mild symptoms and no limitation of normal activities); 3: Fair (moderate symptoms and limitation of some normal activites); 4: Poor (severe symptoms and inability to carry out most normal activities); 5: Very Poor (very severe symptoms which are intolerable and inability to carry out all normal activities).

Other	Change From A4091026 (NCT00863772) Baseline in 36-Item Short-Form Health Survey Version 2 (SF-36v2) Domain Scores at Week 24	SF-36v2 is a self-administered questionnaire evaluating 8 aspects/domains of functional health and wellbeing: physical function, role physical, bodily pain, vitality, general health, social function, role emotional and mental health. The total score for each domain is scaled 0-100 (100 = highest level of functioning). Change from baseline >0 indicates an improvement.	A4091026: Baseline, A4091040: Week 24
Other	Change From A4091026 (NCT00863772) Baseline in 36-Item Short-Form Health Survey Version 2 (SF-36v2) Physical and Mental Component Scores at Week 24	SF-36v2 is a self-administered questionnaire evaluating 8 aspects/domains of functional health and wellbeing: physical function, role physical, bodily pain, vitality, general health, social function, role emotional and mental health. Total score for each aspect were scaled 0-100 (100=highest level of functioning). For obtaining physical and mental component scores, z-score for each scale = (observed score -mean score for general 1990 United States [US] population)/corresponding standard deviation. The 2 component scores were obtained by multiplying each aspect z-score by physical or mental factor score coefficient (1990 general US population) and summing the eight products. Component scores indicated how many standard deviations higher (in case of positive z-score [better functioning])/lower (in case of negative z-score [worse functioning]) participant's value was relative to the mean of the reference population. Change from baseline >0 indicates an improvement.	A4091026: Baseline, A4091040: Week 24
