Safety And Efficacy In Long Term Use Of Lyrica (Regulatory Post Marketing Commitment Plan)

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.

Time frame: From Week 1 to Week 104 at maximum

Population: The analysis population for this outcome measure was the baseline analysis population, which comprised of participants who satisfied the criteria of safety analysis population and had received LYRICA Capsules at least once.

The pain experienced at Week 104 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 104 was presented along with standard deviation.

Time frame: Baseline and at Week 104

Population: The analysis population for this outcome measure comprised of participants for whom the evaluation outcome of participant-rated pain score was available and who satisfied the inclusion criteria among the baseline analysis population.

The sleep interference (inability to sleep because of pain) experienced at Week 104 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 104 was presented along with standard deviation.

Time frame: Baseline and at Week 104

Population: The analysis population for this outcome measure comprised of participants for whom the evaluation outcome of participant-rated sleep interference score was available and who satisfied the inclusion criteria among the baseline analysis population.

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 104 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.

Time frame: At Week 104

Population: The analysis population for this outcome measure comprised of participants for whom the evaluation outcome of clinical effectiveness was available and who satisfied the inclusion criteria among the baseline analysis population. Of these, participants evaluated as impossible to judge were excluded from the analysis population.

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.

Time frame: From Week 1 to Week 104 at maximum

Population: The analysis population for this outcome measure was the baseline analysis population, which comprised of participants who satisfied the criteria of safety analysis population and had received LYRICA Capsules at least once.

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.

Time frame: From Week 1 to Week 104 at maximum

Population: The analysis population for this outcome measure was the baseline analysis population, which comprised of participants who satisfied the criteria of safety analysis population and had received LYRICA Capsules at least once.

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.

Time frame: From Week 1 to Week 104 at maximum

Population: The analysis population for this outcome measure was the baseline analysis population, which comprised of participants who satisfied the criteria of safety analysis population and had received LYRICA Capsules at least once.

The patient's impression (patient global impression of change \[PGIC\]) at Week 104, as compared to the baseline condition (including the first day of treatment), was rated by participants on a 7-grade scale.

Time frame: At Week 104

Population: The analysis population for this outcome measure comprised of participants for whom the evaluation outcome of PGIC was available and who satisfied the inclusion criteria among the baseline analysis population.

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.

Time frame: From Week 1 to Week 104 at maximum

Population: The analysis population for this outcome measure was the baseline analysis population, which comprised of participants who satisfied the criteria of safety analysis population and had received LYRICA Capsules at least once.

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.

Time frame: From Week 1 to Week 104 at maximum

Population: The analysis population for this outcome measure was the baseline analysis population, which comprised of participants who satisfied the criteria of safety analysis population and had received LYRICA Capsules at least once.

The physician's impression (clinical global impression of change \[CGIC\]) at Week 104, as compared to the baseline condition (including the first day of treatment), was rated by the physician on a 7-grade scale.

Time frame: At Week 104

Population: The analysis population for this outcome measure comprised of participants for whom the evaluation outcome of CGIC was available and who satisfied the inclusion criteria among the baseline analysis population.
