Brief summary
The primary objective of the study is to evaluate the efficacy of fasinumab in relieving Chronic low back pain (CLBP) as compared to placebo in participants with a clinical diagnosis of moderate-to-severe non-radicular CLBP and Osteoarthritis (OA) of the knee or hip when treated for up to 16 weeks. The secondary objectives of the study are: To evaluate the safety and tolerability of fasinumab compared to placebo when participants with a clinical diagnosis of moderate-to-severe non-radicular CLBP and OA of the knee or hip are treated for up to 16 weeks; To characterize the concentrations of fasinumab in serum over time when participants with a clinical diagnosis of moderate-to-severe non-radicular CLBP and OA of the knee or hip are treated for up to 16 weeks; To evaluate the immunogenicity of fasinumab when treated for up to 16 weeks in participants with a clinical diagnosis of moderate-to-severe non-radicular CLBP and OA of the knee or hip.

Time frame: Up to Week 36
| Arm | Measure | Group | Value (NUMBER) |
|---|---|---|---|
| Fasinumab-matching Placebo | Number of Peripheral Sensory Adverse Events (AEs) That Require a Neurology Consultation | Paraesthesia events | 1 Peripheral Sensory Adverse Events (AEs) |
| Fasinumab-matching Placebo | Number of Peripheral Sensory Adverse Events (AEs) That Require a Neurology Consultation | Hypoaesthesia events | 1 Peripheral Sensory Adverse Events (AEs) |
| Fasinumab 3 mg SC Q4W | Number of Peripheral Sensory Adverse Events (AEs) That Require a Neurology Consultation | Hypoaesthesia events | 0 Peripheral Sensory Adverse Events (AEs) |

Number of Sympathetic Nervous System (SNS) Dysfunction Events
Potential events of sympathetic nervous system (SNS) dysfunction were monitored throughout the study through physical examination, AE reporting, assessment of orthostatic hypotension, and the Survey of Autonomic Symptoms. Sympathetic nervous system dysfunction was diagnosed after consultation with an appropriate specialist, such as a neurologist and/or cardiologist.
Time frame: Up to Week 36
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Fasinumab-matching Placebo | Number of Sympathetic Nervous System (SNS) Dysfunction Events | 0 Sympathetic NS Dysfunction Events |
| Fasinumab 3 mg SC Q4W | Number of Sympathetic Nervous System (SNS) Dysfunction Events | 0 Sympathetic NS Dysfunction Events |
Number of Treatment-Emergent Adverse Events (TEAEs)
Treatment-emergent adverse events (TEAEs) are defined as those that are not present at baseline or represent the exacerbation of a pre-existing condition during the on-treatment period.
Time frame: Up to Week 16
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Fasinumab-matching Placebo | Number of Treatment-Emergent Adverse Events (TEAEs) | 33 Treatment-Emergent Adverse Events |
| Fasinumab 3 mg SC Q4W | Number of Treatment-Emergent Adverse Events (TEAEs) | 14 Treatment-Emergent Adverse Events |
