Safety And Efficacy Of Lyrica (Regulatory Post Marketing Commitment Plan)

Study Overview
=================
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.

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Pregabalin (Lyrica) capsule<br>Patients administered Pregabalin capsule. | Drug: Pregabalin (Lyrica) capsule<br>* 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.<br>* Other names: Lyrica® Capsules 25 mg, Lyrica® Capsules 75 mg, Lyrica® Capsules 150 mg;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Adverse Drug Reaction | An adverse drug reaction (ADR) was any untoward medical occurrence attributed to LYRICA Capsules in a participant who received LYRICA Capsules. Relatedness to LYRICA Capsules was assessed by the physician. | 13 weeks at maximum | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Serious Adverse Drug Reaction | An adverse drug reaction (ADR) was any untoward medical occurrence attributed to LYRICA Capsules in a participant who received LYRICA Capsules. A serious ADR was an ADR resulting in any of the following outcomes or deemed significant for any other reason: death; life-threatening experience (immediate risk of dying); initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly. Relatedness to LYRICA Capsules was assessed by the physician. | 13 weeks at maximum | 
| The Percentage of Participants With Adverse Drug Reaction Unexpected From Japanese Package Insert | An adverse drug reaction (ADR) was any untoward medical occurrence attributed to LYRICA Capsules in a participant who received LYRICA Capsules. Expectedness of the adverse event was determined according to the Japanese package insert. Relatedness to LYRICA Capsules was assessed by the physician. | 13 weeks at maximum | 
| Number of Participants With Adverse Drug Reactions Related to Peripheral Edema or Other Edema-related Events | An adverse drug reaction (ADR) was any untoward medical occurrence attributed to LYRICA Capsules in a participant who received LYRICA Capsules. Relatedness to LYRICA Capsules was assessed by the physician. Occurrence of ADRs related to peripheral edema or other edema-related events was evaluated. | 13 weeks at maximum | 
| Number of Participants With Adverse Drug Reactions Related to Dizziness, Somnolence, Loss of Consciousness, Syncope, and Potential for Accidental Injury | An adverse drug reaction (ADR) was any untoward medical occurrence attributed to LYRICA Capsules in a participant who received LYRICA Capsules. Relatedness to LYRICA Capsules was assessed by the physician. Occurrence of ADRs related to dizziness, somnolence, loss of consciousness, syncope, and potential for accidental injury was evaluated. | 13 weeks at maximum | 
| Number of Participants With Adverse Drug Reactions Related to Vision-related Events | An adverse drug reaction (ADR) was any untoward medical occurrence attributed to LYRICA Capsules in a participant who received LYRICA Capsules. Relatedness to LYRICA Capsules was assessed by the physician. Occurrence of ADRs related to vision-related events was evaluated. | 13 weeks at maximum | 
| Clinical Effectiveness Rate | Clinical 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. | At Week 13 | 
| Change From Baseline in Participant-rated Pain Score at Week 13 | The 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. | Baseline and at Week 13 | 
| Change From Baseline in Participant-rated Sleep Interference Score at Week 13 | The 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. | Baseline and at Week 13 | 
| Patient's Impression (PGIC) at Week 13 | The 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. | At Week 13 | 
| Physician's Impression (CGIC) at Week 13 | The 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. | At Week 13 |
