About this trial

The treatment of anorexia nervosa often proves to be difficult. There are no drugs that work specifically for the treatment of anorexia nervosa. Experimental administration of metreleptin (synthetically produced leptin) to patients with anorexia nervosa has produced positive results. This study tests the effect of metreleptin in comparison with placebo, which could potentially make treatment easier. The aim of the study is to investigate whether treatment with metreleptin can help to reduce the symptoms of anorexia nervosa and improve mood and weight.

Treatments tested in this trial

  • Metreleptin

    Drug

    Metreleptin 3 mg is packaged in 3 ml Type I glass vials with chlorobutyl rubber stoppers, and aluminum seals with plastic flip-off caps. The vials are stored in refrigerator (2 - 8°C) and protected from light. Metreleptin for injection is a sterile, white, solid lyophilised cake. Prior to patient use, the content of a vial is reconstituted with 0.6 ml of water for injection for a final formulation of 10 millimolar (mM) glutamic acid, 2% glycine, 1% sucrose, 0.01% polysorbate 20, potential hydrogen (pH) 4.25. The resulting solution is administered by subcutaneous injection.

  • Sodium chloride

    Drug

    The placebo will consist of sterile 0.9% saline (Sodium chloride), drawn up from a 10 ml i.v. vials. The placebo will be administered as an subcutaneous injection in an identical procedure as the metreleptin verum.

Trial outcomes

Primary outcomes

1

Clinician-rated depression on the 17 point Hamilton Depression Scale (HAMD-17) in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up

HAMD-17 is a semi-structured interview and consists of 17 items assessing symptoms of depression from the perspective of the clinician. Possible scores range from 0 (no depressive symptom) to 4 (strong depressive symptom). The higher the total score, the more severe the depressive symptoms.

Time frame
Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
2

Body weight status in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up

Body weight status will be indicated by weight in kilograms (kg).

Time frame
Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)

Secondary outcomes

1

Subjective depression by the Beck Depression Inventory-II (BDI-II) in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up

The Beck Depression Inventory-II is a self-report rating inventory that measures characteristic attitudes and symptoms of depression with 21 items, ranging from 0 (no depressive symptoms) to 3 (strong depressive symptoms). The higher the total score, the more severe the depressive symptoms.

Time frame
Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
2

Functional brain connectivity in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up

For assessment of intrinsic functional connectivity in the brain, functional MRI images will be acquired for each patient. A region-of-interest analysis and calculating correlations between any pair of two brain regions, obtaining a connectivity matrix, will be done.

Time frame
Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
3

Anorexia Nervosa psychopathology assessed by the Eating Disorders Examination Questionnaire (EDE-Q) in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up

The Eating Disorders Examination Questionnaire (EDE-Q) is the self-report version of the Eating Disorder Examination (EDE). The 22 items on the four subscales of restraint, eating concern, weight concern, and shape concern are used to assess eating disorder-specific characteristics in their current manifestations during the last 28 days. 7-point rating scales are used to assess frequencies from 0 (characteristic was not present) to 6 (characteristic was present every day or to an extreme degree). Six further, non-scale-forming items also measure the frequency of diagnostically relevant core behaviors over the last 28 days. The EDE-Q is evaluated by calculating subscale mean values for the Restraint, Eating Concern, Weight Concern and Shape Concern subscales and a total score. At Baseline, Post Treatment and intermediate measurements, the instruction of EDE-Q will be modified to refer to a shortened shortened observation time (last week).

Time frame
Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
4

External rated hyperkinesia assessed by the Structured Inventory for Anorexic and Bulimic Eating Disorders (SIAB, item 42) in the metreleptin-assisted therapy group compared to placebo-therapy group between Baseline, Post Treatment and 5 weeks Follow Up

Hyperkinesia will be assessed with only one item (item 42) from the Structured Inventory for Anorexic and Bulimic Eating Disorders (SIAB). This Inventory is used to record the entire spectrum of eating disorder symptoms. Item 42 assesses excessive physical exercise ranging from 0 (no physical exercise) to 4 (very frequent physical exercise).

Time frame
Baseline (day -1), Post Treatment (day 14) and after 5 weeks Follow Up (day 49)
