About this study

Official title: Open Labeled, Non-randomized, Study of Efficacy and Safety of Gralise in Fibromyalgia Patients.

To determine Gralise in treating fibromyalgia pain:

  • efficacy
  • safety
Read the detailed description

Subject must carry a diagnosis of fibromyalgia based on American College of Rheumatology (ACR) criteria for fibromyalgia

  • Patient may be gaba-analogue (Pregabalin, trade name: lyrica, or Gabapentin, trade name: Neurontin) naïve, or had been on other gaba analogue before, and discontinued for lack of efficacy.
  • Patient who had allergic reaction or serious adverse reactions will not be included in this study.
  • Patient will start with starter pack of Gralise and will reach therapeutic dose of 1800 mg per day by end of 2 weeks.
  • Drug is to be taken with meal, once a day in the evening; once patient has reached the therapeutic dose of 1800 mg, patient will come in for visit, at which point the PI will evaluate the patient and may increase or decrease the dosage, but patient may not increase or decrease the dose of medication at his /her discretion.
  • During study, patient will have total of 5 visits, 4 of which will be for duration patient will be on Gralise, and the last visit will be for tapering off the medication.
  • During study, patient is asked keep a paper diary on which patient will record the numeric pain scale from Fibromyalgia, time the medication was taken, dose of medication, and any side effects.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Gabapentin ERDrug

    Also called Gralise

    Patient who are on gralise will report efficacy by rating his or her pain rating on a digital pain scale (11 points) from 0 to 10 on each scheduled clinical visits, which will be compared to their pain level at baseline.

    In addition, patients will also record the doses and any adverse effects that might arise during the trial in a diary provided by the study. All information will be recorded in a paper diary that will be followed by coordinator during each follow up visits.

Study groups in NCT02052414
Study groupRoleWhat they receive
Gralise (Gabapentin ER)ExperimentalAll patients will be treated with Gralise. Patients who are on pregabalin or gabapentin (lyrica or neurontin) will need to wash off the medication before starting Gralise. Patients who are ready to take Gralise will start with starter pack, and will gradually titrate the dose up to 1800mg per day. After that, patient will take 1800mg per day out of the bottle. Patient will be seen in clinic at 4weeks intervals for first 4 visits, and then there will be end of the study visit on week 15. On visit 4, week 12 of treatment, patients will be taught to taper off the study medication.
Receives: Drug: Gabapentin ER

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Numeric Pain Rating System (NPRS)

    Fibromyalgia pain experienced by study subjects will be captured using NPRS at baseline visit, at each follow visits that are scheduled to occur every 4 weeks over 12 weeks of treatment period, and at the end of treatment visit that will occur 3 weeks after treatment period (12 weeks treatment period + 3 weeks = 15 weeks). Any difference in NPRS scores between baseline and any subsequent visits will indicate the magnitude of pain relief as reflected in digital scale of 0-10 (0=no pain, 10=worst pain imaginable).

    Measured: 15 weeks

Secondary outcomes (3)
  1. Medical Outcome Study (MOS) Sleep Questionnaires

    Medical Outcomes Study (MOS) sleep questionnaires to assess how Fibromyalgia impacts patients' sleep in various areas.

    Specifically, Data reported below measured number of hours subjects spent per night sleeping. MOS sleep questionnaires were assessed at each follow up visits. (visits 1, 2, 3, 4, and 5).

    Measured: 15 weeks

  2. Self Reported Side Effects.

    Side / adverse effects were assessed at each follow up visits and resulted are as follows.

    Measured: 15 Weeks

  3. Fibromyalgia Impact Questionnaire (FIQ)

    The Fibromyalgia Impact Questionnaire (FIQ) is an instrument designed to quantitate the overall impact of fibromyalgia over many dimensions (e.g. function, pain level, fatigue, sleep disturbance, psychological distress etc.). It is scored from 0 to 100 with the latter number being the worst case. The average score for patients seen in tertiary care settings is about 50. The FIQ is widely used to assess change in fibromyalgia status.

    Measured: 15 weeks.
