Brief summary

The objective of this Investigation is to evaluate the safety and efficacy of Lyrica in medical practice. Also, occurrence of unknown and known adverse drug reactions (ADRs) in subjects treated with Lyrica will be monitored during the survey period, and whether an additional treatment outcome investigation and/or a post-marketing clinical study is required in the future will be determined.

Detailed description

All the patients whom an investigator prescribes the first Lyrica® should be registered consecutively until the number of subjects reaches target number in order to extract patients enrolled into the investigation at random.

Interventions

Lyrica® Capsules depending on the investigator prescription. Frequency and duration are according to Package Insert as follows. The usual adult dosage for oral use begins at 150 mg/day of pregabalin in twice daily, and should be gradually increased to 300 mg/day over 1 week or more and should be orally administered twice daily. Dosage should be adjusted, depending on age or symptoms. However, the daily maximum dose should not be beyond 600 mg, and should be orally administered twice daily.

Relatedness to LYRICA Capsules was assessed by the physician.
Change From Baseline in Participant-rated Pain Score at Week 13Baseline and at Week 13The pain experienced at Week 13 during the past 24 hours was rated by participants at the time of getting up in the morning on an 11-grade scale, ranging from 0 (no pain) to 10 (the most severe pain possible). Mean change from baseline in participant-rated pain score at Week 13 was presented along with standard deviation. For the participants who completed or discontinued the treatment before Week 13, the data at the time of the completion or discontinuation was used for the analysis.
Change From Baseline in Participant-rated Sleep Interference Score at Week 13Baseline and at Week 13The sleep interference (inability to sleep because of pain) experienced at Week 13 during the past 24 hours was rated by participants at the time of getting up in the morning on an 11-grade scale, ranging from 0 (no disturbance) to 10 (totally unable to sleep because of pain). Mean change from baseline in participant-rated sleep interference score at Week 13 was presented along with standard deviation. For the participants who completed or discontinued the treatment before Week 13, the data at the time of the completion or discontinuation was used for the analysis.
Patient's Impression (PGIC) at Week 13At Week 13The patient's impression (patient global impression of change \[PGIC\]) at Week 13, as compared to the baseline condition (including the first day of treatment), was rated by participants on a 7-grade scale. For the participants who completed or discontinued the treatment before Week 13, the data at the time of the completion or discontinuation was used for the analysis.
Physician's Impression (CGIC) at Week 13At Week 13The physician's impression (clinical global impression of change \[CGIC\]) at Week 13, as compared to the baseline condition (including the first day of treatment), was rated by the physician on a 7-grade scale. For the participants who completed or discontinued the treatment before Week 13, the data at the time of the completion or discontinuation was used for the analysis.
Clinical Effectiveness RateAt Week 13Clinical effectiveness of LYRICA Capsules was determined by the physician based on the following categories: (1) effective, (2) ineffective, or (3) impossible to judge at Week 13 of the treatment. Clinical effectiveness rate, which was defined as the percentage of participants who achieved clinical effectiveness over the total number of the analysis population, was presented along with the corresponding 2-sided 95% CI. For the participants who completed or discontinued the treatment before Week 13, the data at the time of the completion or discontinuation was used for the analysis.
