Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
11 Subjects enrolled in the study and started a single-blind placebo lead-in period. Of those, 5 were randomized. 6 subjects did not continue and were either lost to follow-up, chose not to continue, or exhibited a large placebo response and no longer met the criteria to continue in the study.

Reporting Groups
Placebo, Then Gralise Subjects may receive a pill with no medicine.
Gralise Then Placebo

Gralise (a long acting gabapentinoid)

Gralise: Subjects will start at 600mg and titrate up by 600mg a week for two weeks (to 1800mg), then remain on 1800mg steady state dose of medication (or placebo pills) for 2 weeks. If intolerable side effects occur, the dose may be reduced to last tolerable dose at the discretion of the PI. A 2-week down-titration will be used. Subjects will have 1 week of “wash-out” before repeating the above procedure for the other arm of the study (placebo or medication).

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
This study was terminated early due to low recruitment. Therefore, the data presented represents a very small sample, with low 'n's in each group. The data tables represent all available data for the small sample.
