Primary Outcome Measures :
  1. Percentage of Participants Classified as Responders at Week 12 of the Double- Blind Period [ Time Frame: Week 12 ]
    A participant who meets all of the following criteria will be classified as a responder: (1)Has a reduction of >=30% in mean pain score compared with baseline (2)Has not discontinued randomized treatment before the end of Week 12 of the double-blind period (3)Has not taken prohibited pain medication before the end of Week 12 of the double-blind period.

  2. Number of Participants Experiencing Adverse Events (AEs) and Serious Adverse Events (SAEs) During the Long Term Extension (LTE) Period [ Time Frame: Baseline up to Week 104 of the LTE ]
    An AE is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An SAE was defined as any untoward medical occurrence that at any dose: results in death; in the view of the Investigator, places the subject at immediate risk of death (a life-threatening event; however, this does not include an event that, had it occurred in a more severe form, might have caused death); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; or results in a congenital anomaly/birth defect.


Secondary Outcome Measures :
  1. Percentage of Participants Classified as Responders Achieving Patient Global Impression of Change (PGIC) Response at Week 12 of the Double-Blind Period [ Time Frame: Week 12 ]
    A participant who meets all of the following criteria will be classified as a responder: (1) Achieving Patient Global Impression of Change (PGIC) response of "Much Improved" or "Very Much Improved" at Week 12 of the double-blind period (2) has not discontinued randomized study treatment before the end of Week 12 of the double-blind period, (3)has not taken prohibited pain medication before the end of Week 12 of the double-blind period. PGIC is a 7-point selfreport scale depicting a participant's rating of overall improvement. Participants rate their change as "very much improved," "much improved," "minimally improved," "no change," "minimally worse," "much worse," or "very much worse."

  2. Percentage of Participants Classified as Responders Achieving >=50 Percent Reduction From Baseline Mean Number of Paroxysms at Week 12 [ Time Frame: Week 12 ]
    A participant who meets all of the following criteria will be classified as a responder: (1) Achieving >=50 percent reduction from baseline mean number of paroxysms at Week 12 (2) has not discontinued randomized study treatment before the end of Week 12 of the double-blind period, (3)has not taken prohibited pain medication before the end of Week 12 of the double-blind period.11-point Pain Intensity Numerical Rating Scale (PINRS) is used to assess TM paroxysmal pain. PINRS is an 11-point pain intensity numerical rating scale, where 0=no pain and 10=worst possible pain. Weekly average is defined as the total of severity scores during a week divided by the total number of paroxysms during that week.

  3. Percentage of Participants Classified as Responders Achieving >=50 Percent Reduction From Baseline Mean Pain Score at Week 12 [ Time Frame: Week 12 ]
    A participant who meets all of the following criteria will be classified as a responder: (1) Achieving >=50 percent reduction from baseline mean pain score at Week 12 (2) has not discontinued randomized study treatment before the end of Week 12 of the double-blind period, (3)has not taken prohibited pain medication before the end of Week 12 of the double-blind period. Pain score is a 11-point numerical rating scale where 0 = no pain; 10 = maximum pain imaginable. Higher scores representing more pain.

  4. Number of Participants Experiencing Adverse Events (AEs) and Serious Adverse Events (SAEs) During the Double Blind Period [ Time Frame: Up to Week 14 of Double blind period ]
    An AE is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An SAE was defined as any untoward medical occurrence that at any dose: results in death; in the view of the Investigator, places the subject at immediate risk of death (a life-threatening event; however, this does not include an event that, had it occurred in a more severe form, might have caused death); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; or results in a congenital anomaly/birth defect.

  9. Change From Baseline in Mean Worst Pain Score During the Long Term Extension (LTE) Period [ Time Frame: Baseline, Week 1 through Week 104 ]
    Pain score is a 11-point numerical rating scale where 0 = no pain; 10 = maximum pain imaginable. Higher scores representing more pain.

  10. Percentage of Participants with >=50% Reduction From Baseline in Mean Number of Paroxysms During Long Term Extension (LTE) Period [ Time Frame: Week 1 through Week 104 ]
    11-point Pain Intensity Numerical Rating Scale (PI-NRS) is used to assess TM paroxysmal pain.

    PGIC is a 7-point self-report scale depicting a participant's rating of overall improvement. Participants rate their change as "very much improved," "much improved," "minimally improved," "no change," "minimally worse," "much worse," or "very much worse." Participants with "Much Improved or "Very Much Improved" will be reported.

  13. Change From Baseline in the PENN-FPS-R Score by Visit During the Long Term Extension (LTE) Period [ Time Frame: Baseline, Day 1, Week 2, 4, 6, 8, every 12 weeks up to Week 104 ]
    A self-report measure of pain intensity adapted from the Faces Pain Scale to make it possible to score the sensation of pain on the widely accepted 0-to-10 metric; "0" equals "No pain" and "10" equals "Very much pain.

  14. Change From Baseline in the EQ-5D-5L Score by Visit During the Long Term Extension (LTE) Period [ Time Frame: Baseline, Day 1, Week 4, 8, every 12 weeks up to Week 104 ]
    EQ-5D-5L is a standardized, subject-rated instrument for use as a measure of health outcomes. The EQ 5D-5L includes 2 components: the EQ-5D-5L descriptive system and the EQ-Visual Analog Scale (EQ-VAS). The EQ-5D-5L descriptive system provides a profile of the participant's health state in 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). For each dimension, the participant is instructed to indicate whether he or she has "no problems" (1), "some problems" (2), or "severe problems" (3). A negative change from Baseline indicates improvement.

  15. Change From Baseline in the WPAI Neuropathic Pain (V2.0) Score by Visit During the Long Term Extension (LTE) Period [ Time Frame: Baseline, Day 1, Week 4, 8, every 12 weeks up to Week 104 ]
    The WPAI questionnaire is a validated instrument to measure impairments in work and activities. The WPAI yields four types of scores: 1. Absenteeism (percentage of work time missed) 2. Presenteeism (percentage of impairment at work/reduced on-the-job effectiveness) 3. Work productivity loss (percentage of overall work impairment [absenteeism plus presenteeism]) 4. Activity Impairment (percentage of overall activity impairment). WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity.
