Secondary outcomes (17)
Change From Parent Study Baseline in Neuropathy Impairment Score (NIS) at Week 4, 8, 16, 24, 32, 40, 48, 56, 64 and 72
NIS constitutes sum of 37 standard items of neuromuscular examination used to assess muscle strength, reflexes and sensation. Each item is scored separately for left and right sides. Components of muscle weakness (24 items) scored on a scale: 0 (normal) to 4 (paralysis), with higher score=more weakness; components of reflexes and sensation (13 items) scored on a scale: 0= normal, 1= decreased or 2= absent. Total NIS score range 0 (no impairment) to 244 (maximum impairment), higher score = more impairment. Parent study baseline value calculated as average of pre-dose measurements of participants from study A4091011, A4091014, A4091015 and A4091018.
Measured: Baseline of the parent study (A4091011, A4091014, A4091015, A4091018); A4091016: Week 4, 8, 16, 24, 32, 40, 48, 56, 64, 72
Number of Participants With Anti-drug Antibodies (ADA) for Tanezumab
Human serum anti-drug antibody (ADA) samples were analyzed for the presence or absence of anti-tanezumab antibodies by using the semi-quantitative enzyme-linked immunosorbent assay (ELISA). Same participant may have positive ADA result at more than 1 time point.
Measured: A4091016: Day 1, Week 16, 24, 40, 56, 72, 80 or Early Termination (ET: anytime till Week 80)
Number of Participants With Clinically Significant Changes From Baseline to Week 80 in Physical Examination Findings
Physical examination included examination of following sites in addition to general examination: abdomen, ears, extremities, eyes, head, heart, musculoskeletal, neck, nose, skin, throat and thyroid. Clinically significant changes were judged by investigator.
Measured: Baseline (Day 1) up to Week 80
Number of Participants With Clinically Significant Abnormality in Vital Signs
Following parameters were analyzed for examination of vital signs: body temperature, blood pressure, heart rate and respiratory rate. Number of participants with clinically significant abnormality in vital signs were judged by investigator and reported as adverse events were presented.
Measured: A4091016: Baseline (Day 1) up to Week 80
Change From Parent Study Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale Score at Week 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96 and 104
The WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis in index knee or hip joint during past 48 hours. The WOMAC pain score is calculated as mean of the scores from 5 individual questions scored on a numerical rating scale (NRS) of 0 (minimum pain) to 10 (maximum pain), where higher scores indicate higher pain. Total score range for WOMAC pain subscale score is 0 (minimum pain) to 10 (maximum pain), where higher scores indicate higher pain. Parent study baseline value calculated as average of pre-dose measurements of the participants from study A4091011, A4091014, A4091015 and A4091018.
Measured: Baseline of the parent study (A4091011, A4091014, A4091015, A4091018); A4091016: Week 4, 8, 16, 24, 32, 40, 48,56, 64, 72, 80, 88, 96, 104
Change From Parent Study Baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Physical Function Subscale Score at Week 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96 and 104
The WOMAC physical function subscale is a 17-item questionnaire used to assess the degree of difficulty experienced due to osteoarthritis in index knee or hip joint during past 48 hours. The WOMAC physical function score is calculated as mean of the scores from 17 individual questions scored on a NRS of 0 (minimum difficulty) to 10 (maximum difficulty), where higher scores indicate worse function. Total score range for WOMAC physical function subscale score is 0 (minimum difficulty) to 10 (maximum difficulty), where higher scores indicate worse function. Parent study baseline value calculated as average of pre-dose measurements of the participants from study A4091011, A4091014, A4091015 and A4091018.
Measured: Baseline of the parent study (A4091011, A4091014, A4091015, A4091018); A4091016: Week 4, 8, 16, 24, 32, 40, 48,56, 64, 72, 80, 88, 96, 104
Change From Parent Study Baseline in Patient Global Assessment (PGA) of Osteoarthritis at Week 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96 and 104
Participants answered: "Considering all the ways your osteoarthritis in your knee/hip affects you, how are you doing today?" Participants responded by using a 5-point scale where 1 = very good and 5 = very poor. Higher scores indicate worse condition. Parent study baseline value calculated as average of pre-dose measurements of the participants from study A4091011, A4091014, A4091015 and A4091018.
Measured: Baseline of the parent study (A4091011, A4091014, A4091015, A4091018); A4091016: Week 4, 8, 16, 24, 32, 40, 48,56, 64, 72, 80, 88, 96, 104

The WOMAC pain score is calculated as mean of the scores from 5 individual questions scored on a numerical rating scale (NRS) of 0 (minimum pain) to 10 (maximum pain), where higher scores indicate higher pain. Total score range for WOMAC pain subscale score is 0 (minimum pain) to 10 (maximum pain), where higher scores indicate higher pain. Parent study baseline value calculated as average of pre-dose measurements of the participants from study A4091011, A4091014, A4091015 and A4091018.
Measured: Baseline of the parent study (A4091011, A4091014, A4091015, A4091018); A4091016: Week 4, 8, 16, 24, 32, 40, 48,56, 64, 72, 80, 88, 96, 104

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 10 May 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Treatment Emergent Adverse Events (AEs) And Serious Adverse Events (SAEs) (time frame: A4091016: Baseline (Day 1) up to 112 days after last dose of study medication (up to Week 80)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00809783, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 May 2021.
