Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Saizen®
Drug: Saizen®
Saizen® (Somatropin) 0.006 milligram per kilogram (mg/kg) will be administered subcutaneously daily for 12 months. Dose will be titrated (an increase of 0.2 milligram per day) if the increase in insulin-like growth factor 1 (IGF-1) is less than 50 percent of the baseline value. Dose titrations will be made at Month 1, 3, 7 and 9.
Other Names:
  • Somatropin
Active Comparator: Placebo + Saizen®
Drug: Placebo and Saizen®
Placebo matched to Saizen® will be administered for the first 6 months followed by treatment with Saizen® (Somatropin) 0.006 mg/kg subcutaneously daily for next 6 months. Saizen® dose will be titrated (an increase of 0.2 milligram per day) if the increase in insulin-like growth factor 1 (IGF-1) is less than 50 percent of the baseline value. Dose titrations will be made at Month 7 and 9.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Less Than 11 Tender Points at Month 6
Time Frame: Month 6
The musculoskeletal component in form of pain on palpation in at least 11 of 18 tender point sites is required to fulfill the American College of Rheumatology (ACR) criteria for fibromyalgia syndrome, An important response is considered when the number of tender points falls below 11 since it is the threshold for fibromyalgia diagnosis.
Month 6
Percentage of Participants With Less Than 11 Tender Points at Month 12
Time Frame: Month 12
The musculoskeletal component in form of pain on palpation in at least 11 of 18 tender point sites is required to fulfill the ACR criteria for fibromyalgia syndrome, An important response is considered when the number of tender points falls below 11 since it is the threshold for fibromyalgia diagnosis.
Month 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Fibromyalgia Impact Questionnaire (FIQ) Total Score
Time Frame: Baseline, Month 1, 3, 6, 7, 9 and 12
Fibromyalgia Impact Questionnaire (FIQ) is a 10-item questionnaire that measures physical impairment, well-being, missed work, pain, fatigue, rest, stiffness, anxiety, and depression. Score ranges from 0 (best result - very well) to 100 (worst result - awful).
Baseline, Month 1, 3, 6, 7, 9 and 12
Visual Analog Scale (VAS) Total Score
Time Frame: Baseline, Month 1, 3, 6, 7, 9 and 12
Visual Analog Scale (VAS) is a 100 millimeter (mm) scale. Intensity of pain range: 0 mm=no pain to 100 mm=worst possible pain.
Baseline, Month 1, 3, 6, 7, 9 and 12
EuroQol 5-Dimensions (EQ-5D) Total Score
Time Frame: Baseline, Month 1, 3, 6, 7, 9 and 12
EuroQol 5-Dimensions (EQ-5D) questionnaire is a measure of health status and quality of life (QoL). The EQ-5D defines health in terms of mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Score range for each item is 0 to 3, with 3 being the most severe. Total score range is 0 to 15. Lower scores represent a better QoL.
Baseline, Month 1, 3, 6, 7, 9 and 12
Multidimensional Assessment of Fatigue (MAF) Total Score
Time Frame: Baseline, Month 6 and 12
Multidimensional Assessment of Fatigue (MAF) consists of 16 questions. The score range for first 14 questions is between 0 and 10 for each question while for the last two questions it is 0 and 4 for each question. Total score range for first 14 questions is 0 to 100 and for last two questions is 0 to 8. Lower scores on the each represent the better participant's condition, whereas, higher scores indicate worsening condition.
Baseline, Month 6 and 12
Percentage of Participants With Positive Response on Quality of Life Assessment of Growth Hormone [GH] Deficiency in Adults (QoL AGHDA) Scale
Time Frame: Baseline, Month 6 and 12
Quality of Life Assessment of GH Deficiency in Adults (QoL AGHDA) questionnaire consists of 25 items that evoke yes or no answers. A score of 1 is given to each item affirmed and these are summed to give the total score. The maximum score is 25, which represents a poor quality of life. The minimum score is 0, which represents a good quality of life. Each question has to be answered with a NO/YES and for each YES, one point is added. The more YES, the higher the score and the worse. Decrease in the positive responses is an index of improvement. So, when the percentage of positive responses on the scale decreases, it is considered a response rate.
Baseline, Month 6 and 12
