Detailed Description
Endometriosis is a chronic inflammatory disease1 that affects 5 -10% of reproductive aged women1,2. It is characterized by the presence of uterine endometrium outside the uterus. The condition causes health distress through pelvic pain and decreased QOL. Current therapies to temporarily control symptoms include surgery as well as medical options that prevent pregnancy and have significant side-effects.3,4 The most common symptoms with endometriosis include dysmenorrhea, dyspareunia and NMPP. Ultimately these lead to a decrease in QOL. All current medical therapies to treat endometriosis pain prevent or contradict pregnancy.
Inflammation is a well-established central figure in the pathophysiology of endometriosis(1). Increasingly, data is suggesting that IL-1 is a mediator of inflammation in endometriosis (2, 3). In addition, there are data that single nucleotide polymorphisms at the IL-1A gene locus are associated with endometriosis risk (4). Hence, it is rational to assess anakinra, an IL-1 antagonist, in the control of symptoms and inflammation due to endometriosis. Therefore, we propose this pilot study testing an FDA approved medication (anakinra) to reduce IL-1 and on dysmenorrhea due to endometriosis without stopping periods (a sign of ovulation).
Anakinra is a self-administered subcutaneous injectable medication that is FDA approved for the treatment of rheumatoid arthritis. As an IL-1 antagonist, it works by decreasing inflammation and is administered daily by the patient. Because Anakinra interferes with the immune system functioning, the major concern with the use of Anakinra is reduced resistance to infection. Others include injection site reactions such as redness, itching, rash, and pain. Bruising or bleeding also can occur, but it is rare. These effects usually stop after one - two weeks. Headaches and low white blood cell counts can also occur, but these are very rare. Anakinra should be used with caution in those with chronic kidney disease.
Anakinra is not specifically FDA approved for endometriosis. Although no data on its use in women with endometriosis have been published, there is no reason to expect women with endometriosis would be at any particular or increased risk than those in the general population.
This study is a randomized, double blinded, placebo controlled, cross-over clinical pilot study of 20 women. Patients diagnosed with surgical or imaging-technique proven endometriosis will be randomized to either treatment with an FDA approved medication (Anakinra) or a placebo. This is an investigator initiated single center study sponsored by the Swedish Orphan Biovitrum (SOBI). SOBI will provide the study drug and placebo.

Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: Active Treatment with Anakinra
10 subjects will be enrolled in this group.
Initial treatment will consist of 100mg/day Anakinra, which is the standard, FDA approved dose for the treatment of rheumatoid arthritis.
The randomized treatment will be self-administered by the subject each evening by subcutaneous injection from within 24 hours of the onset of menses until within 24 hours of last menstrual day.

Placebo Comparator: Standard Comparison
10 subjects will be enrolled in this group.
This group will be given placebo injections as their initial treatment.
The placebo is comparable to the anakinra formulation without the active medication - a solution (pH 6.5) containing anhydrous citric acid (1.29 mg), disodium EDTA (0.12 mg), polysorbate 80 (0.70 mg), and sodium chloride (5.48 mg) in water for injection.
These individuals will self-administer the placebo each evening by subcutaneous injection from within 24 hours of the onset of menses until within 24 hours of last menstrual day.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Comparison of the impact of anakinra versus placebo on menstrual pain (dysmenorrhea) using the modified Biberoglu and Behrman scale.
Time Frame: Subjects will complete the baseline questionnaire at Visit 1. Subjects will fill out monthly questionnaires after the administration of either anakinra or placebo during 6 menstrual periods.
|
The primary pain outcome measure is to determine the impact of anakinra on dysmenorrhea due to endometriosis, using the modified Biberoglu and Behrman scale.
The modified Biberoglu and Behrman scale consists of three patient-reported symptoms (dysmenorrhea, dyspareunia, and non-menstrual pelvic pain).
Each of these is separately graded on a scale from 0 to 3, with a max of 9 and higher numbers indicating more severe symptoms.
Changes in dysmenorrhea is the primary endpoint.

Secondary pain outcome measures are to determine the impact of anakinra on dyspareunia and non-menstrual pelvic pain due to endometriosis, using the modified Biberoglu and Behrman scale.
The modified Biberoglu and Behrman scale consists of three patient-reported symptoms (dysmenorrhea, dyspareunia, and non-menstrual pelvic pain).
Each of these is separately graded on a scale from 0 to 3, with a max of 9 and higher numbers indicating more severe symptoms.
Changes in dyspareunia and non-menstrual pelvic pain are secondary pain endpoints.

Subjects will complete the baseline questionnaire at Visit 1. Subjects will fill out monthly questionnaires after the administration of either anakinra or placebo during 6 menstrual periods.
|
Comparison of the impact of anakinra versus placebo on the quality of life using the Endometriosis Health Profile 30 questionnaire (EHP-30), conducted after each course of study medication administration.
Time Frame: Subjects will complete the baseline questionnaire at Visit 1. Subjects will fill out monthly questionnaires after the administration of either anakinra or placebo during 6 menstrual periods.
|
The secondary outcome measure is to determine the impact of anakinra on the quality of life due to endometriosis, using the Endometriosis Health Profile 30 (EHP-30) questionnaire.
The EHP-30 consists of a 30 item instrument that assesses pain, control and powerlessness, social support, emotional well-being, and self image.
Each scale is standardized on a scale of 0 - 100, where 0 indicates the best health status through to 100 worst health status.
|
Subjects will complete the baseline questionnaire at Visit 1. Subjects will fill out monthly questionnaires after the administration of either anakinra or placebo during 6 menstrual periods.
|
Comparison of serum inflammatory markers before and after anakinra administration.
Time Frame: There will be blood tests at the start and end of each of of the subject's next 6 menstrual periods for a total of 12 blood draws.
|
The secondary outcome is to evaluate the effect of anakinra on serum inflammatory markers that are elevated in women with endometriosis.
Relevant inflammatory markers of endometriosis include CRP, CA125, IL-1, IL-4, IL-6, IL-10, BDNF, Glycodelin, and ZAG.
There will be blood tests at the start and end of each of of the subject's next 6 menstrual periods: At the time of each blood draw, we will collect 20 mL (approximately 4 teaspoons) of blood.
This will be needed for each of the 6 study menstrual periods for a total of 12 blood draws.
There will be a total of 240 ml of blood or approximately 16 tablespoons of blood collected throughout the entire study.
