Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in Weekly Mean 24-hour Average Pain Score Using the 11 Point Numerical Rating Scale (NRS) From Baseline to Week 12 | The NRS is an 11-point scale ranging from zero ("no pain") to ten ("pain as bad as you can imagine") for self-reporting of pain by patients. The following parameters were evaluated using the 11-point NRS: 24-hour Average Pain Score and 24-hour Worst Pain Score Patients evaluated their "average pain" and "worst pain" during the past 24 hours in the evening prior to sleep by touching the appropriate corresponding number between zero and ten on a eDiary device. | Baseline up to Week 12 | |
Secondary | Change in Neuropathic Pain Symptom Inventory (NPSI) From Baseline to Week 12 | The Neuropathic Pain Symptom Inventory (NPSI) is a 12 item patient reported outcome measure that contains 10 descriptors representing 5 dimensions of pain (burning pain, deep/pressing pain, paroxysmal pain, evoked pain and paraesthesia/dysesthesia) and 2 temporal items designed to assess pain duration and the number of pain paroxysms. The sum of the responses to the 10 questions (all except temporal questions) was regarded as the total score and was divided by 10 (10 questions). The range of the total score and of the 5 dimensional scores is 0 to 10. Lower values represent better outcomes. | Baseline up to Week 12 | |
Secondary | Change in Brief Pain Inventory-Short Form Interference (BPI-SF) Mean Total Score From Baseline to Week 12 | The BPI-SF is a validated, self-administered (at clinic) questionnaire that assesses pain severity and its mpact on daily functions. Patients were asked to complete the 7-item pain interference scale that assessed the degree to which pain interfered with walking and other physical activity, work, mood, relations with others and sleep using a zero to ten scale with zero being "does not interfere" and ten being "completely interferes". The BPI total score is the sum of the 7 items. Each item ranges from 0 to 10, thus the total score ranges from 0 to 70. Lower values indicate a better outcome. | Baseline up to Week 12 | |
Secondary | Change in Weekly Mean of the 24-hour Worst Pain Score, Using an 11-point NRS, From Baseline to Week 12 | The NRS is an 11-point scale ranging from zero ("no pain") to ten ("pain as bad as you can imagine") for self-reporting of pain by patients. The following parameters were evaluated using the 11-point NRS: 24-hour Average Pain Score and 24-hour Worst Pain Score Patients evaluated their "average pain" and "worst pain" during the past 24 hours in the evening prior to sleep by touching the appropriate corresponding number between zero and ten on a eDiary device. | Baseline up to Week 12 | |
Secondary | Number of Participants Per Patient Global Impression of Change Category at Week 12 | The Patient Global Impression of Change (PGIC) is a patient-reported instrument that measures change in overall status on a scale ranging from one ("very much improved") to seven ("very much worse"). The PGIC is based on the validated Clinical Global Impression of Change scale. The PGIC was to be completed by patients using the electronic tablet at the site | Baseline up to Week 12 | |
Secondary | Percentage of Patients Achieving at Least 30% Pain Reduction at Week 12 on NRS 11 Point Scale | The NRS is an 11-point scale ranging from zero ("no pain") to ten ("pain as bad as you can imagine") for self-reporting of pain by patients. The number of patients with observed response, i.e. a decrease of 30% units in weekly mean of the 24-hour average pain score NRS. Logistic regression model with region, treatment, sex, use of PHN medications (yes/no) as factors and age and baseline NRS as covariates. An odds ratio >1 = higher chance of a clinically important improvement. | Baseline up to Week 12 | |
Secondary | Percentage of Patients Achieving at Least 50% Pain Reduction at Week 12 on NRS 11 Point Scale | The NRS is an 11-point scale ranging from zero ("no pain") to ten ("pain as bad as you can imagine") for self-reporting of pain by patients. The number of patients with observed response, i.e. a decrease of 50% units in weekly mean of the 24-hour average pain score NRS. Logistic regression model with region, treatment, sex, use of PHN medications (yes/no) as factors and age and baseline NRS as covariates. An odds ratio >1 = higher chance of a clinically important improvement. | Baseline up to Week 12 | |
Secondary | Mean Change in Insomnia Severity Index (ISI) From Baseline to Week 12 | Patients were asked to complete the ISI using five-point Likert-style scale as a measure of perceived sleep difficulties. The questionnaire assessed the severity of insomnia, satisfaction with current sleep pattern, sleep interference, "noticeability" of sleeping problem to others and concern about sleeping problems. The scale consists of 7 items. The sum of seven items represents the total score. Each of the 7 items is scored using a range from 0 to 4, thus the total score values ranges from zero to 28. Lower values represent better outcomes. | Baseline up to Week 12 | |
Secondary | Plasma Pharmacokinetics (PK) Concentrations at Week 8 and 12 | Due to the premature termination of the study, the number of patients and observations providing PK data was much smaller than planned, and no PK model was developed. As a consequence, no PK parameters (Cmax, Tmax, AUC) were derived for this study. Only, summary statistics of the plasma concentrations were calculated | Week 8 (Prior dose, 1-3 hours, 4-6 hours), Week 12 (Prior dose, 1-3 hours, 4-6 hours) | |
Secondary | Percentage of Patients Who Required Rescue Medication in Double-blind Treatment Period | Patients were allowed to take acetaminophen/paracetamol up to a maximum of 3 g daily (divided into 4 times/day) for unacceptable pain due to any reason during the study. This medication use was to be recorded in eDiary prior to use. Percentages of patients presented are those who required rescue meds within 7 days prior to visit. | Baseline and weekly up to 12 weeks, once during double-blind period | |
Secondary | Percentage of Patients Who Required Rescue Medication in Treatment Withdrawal Period | Patients were allowed to take acetaminophen/paracetamol up to a maximum of 3 g daily (divided into 4 times/day) for unacceptable pain due to any reason during the study. This medication use was to be recorded in eDiary prior to use. Percentages of patients presented are those who required rescue meds within 7 days prior to visit. | Week 12 to Week 13 (planned duration subject to varibility in visit scheduling) | |
Secondary | Time to First Rescue Medication Intake | Patients were allowed to take acetaminophen/paracetamol up to a maximum of 3 g daily (divided into 4 times/day) for unacceptable pain due to any reason during the study. This medication use was to be recorded in eDiary prior to use. Patients who did not take any rescue medication were censored at the last date of double-blind treatment period. | Baseline up to day 92 | |
Secondary | Treatment Emergent Adverse Events During Urgent Safety Measure (USM) Follow-Up | Participants were instructed to stop taking drug immediately upon termination of study and asked to come in for two unscheduled visits for follow up safety assessments | Approximately from 3 weeks after end of study up to 16 weeks |
