Eine Studie mit Setmelanotid bei erworbener hypothalamischer Fettleibigkeit

16. Juli 2026 aktualisiert von: Rhythm Pharmaceuticals, Inc.

Eine doppelblinde, randomisierte, placebokontrollierte Phase-3-Studie zur Bewertung der Wirksamkeit und Sicherheit von Setmelanotid bei Patienten mit erworbener hypothalamischer Adipositas

Das Ziel dieser Studie ist es herauszufinden, wie gut Setmelanotid wirkt, um Gewichtsreduktion, Hunger und Lebensqualität bei Patienten ab 4 Jahren mit erworbener hypothalamischer Adipositas (HO) zu verbessern. Um festzustellen, wie gut Setmelanotid wirkt und wie sicher es ist, erhalten Patienten mit HO eine tägliche Injektion von entweder Setmelanotid oder Placebo und führen die Studienbewertungen für bis zu 60 Wochen durch.

Pivotal Cohort: Percentage of Participants With ≥5% Reduction From Baseline in BMI (≥18 Years of Age) or ≥0.2-point Reduction From Baseline in BMI Z-score (<18 Years of Age)
Zeitfenster: After approximately 52 Weeks on a Therapeutic Regimen (baseline up to approximately 60 weeks)
BMI was calculated as weight (kg)/height (m^2). BMI Z-Score calculated for participants <18 years old only is a measure of relative weight adjusted for child's age, sex and height at the time of data collection. The Z-Scores were calculated using the World Health Organization's WHO 2007 BMI SAS Macro Package. A Z-score of 0 is equal to the mean of a reference population (i.e., healthy, age and sex-matched individuals). A decrease in BMI Z-score (< 0) indicates a reduction in BMI from Baseline whereas an increase in BMI-Z score (> 0) indicated an increase in BMI from Baseline. Baseline was defined as the most recent measurement prior to the first administration of study drug. Results below represent the percentage of estimated participants with either ≥5% BMI reduction or ≥0.2 point reduction in BMI Z-score by age in each treatment arm as calculated through the MIANALYZE SAS procedure.

Zeitfenster: Baseline, after approximately 52 Weeks on a Therapeutic Regimen (up to approximately 60 weeks)
Change from baseline in hunger scores for participants ≥12 years of age with acquired hypothalamic obesity was evaluated. Hunger score ranged from 0= "not hungry at all" to 10= "hungriest possible" on an 11-point numeric rating scale. On Daily Hunger Questionnaire, each of the 2 items (average hunger and most hunger) was scored separately and averaged on weekly basis. LSM and SE were calculated using ANCOVA model.

Hunger score ranged from 0= "not hungry at all" to 10= "hungriest possible" on an 11-point numeric rating scale. On Daily Hunger Questionnaire, each of the 2 items (average hunger and most hunger) was scored separately and averaged on weekly basis.

Pivotal Cohort: Mean Change From Baseline in the Weekly Average of the Symptoms of Hyperphagia Composite Score in Participants ≥12 Years of Age
Zeitfenster: Baseline, after approximately 52 Weeks on a Therapeutic Regimen (up to approximately 60 weeks)
Participants ≥12 years of age who were able to self-report were administered the Symptoms of Hyperphagia: Patient (Version 1.0). The questionnaire consisted of 4 items related to the frequency of a participant's hunger symptoms on a scale (Never, 1 or 2 times, 3 or more times) over the past 24 hours. The scores on this scale range from 0 to 2 with higher scores indicating more hyperphagia. Daily composite score was derived as the sum of daily answered questions divided by the number of answered questions per day. The weekly average of the daily composite scores equals to the sum of daily composite scores divided by the number of days with a composite score within the 7 identified days prior to the visit. LSM and SE were calculated using ANCOVA model.

BMI Percentile scores are measures of relative weight adjusted for child's age and gender. The percent of the BMI 95th percentile score expresses the participant's BMI as a percentage of the CDC 95th percentile reference population.

Pivotal Cohort: Mean Change From Baseline in Physical Functioning Score and Total Score on the Impact of Weight on Quality of Life-Lite (IWQOL)
Zeitfenster: Baseline, after approximately 52 Weeks on a Therapeutic Regimen (up to approximately 60 weeks)
The IWQOL-Lite-Clinical Trials (administered to participants ≥18 years of age) is a validated 20-item self-report measure of obesity-specific quality of life questionnaire. It assessed 2 primary domains of obesity-related health-related quality of life (HRQoL): physical (7 items) and psychosocial (13 items). Each item was rated on a scale from 0 (worst) to 100 (best), with higher scores indicating better levels of functioning. It provided composite scores for each domain, as well as a total score, all ranging from 0 (worst) to 100 (best). Higher scores reflect better levels of functioning and quality of life. LSM and SE were calculated using ANCOVA model.

Pivotal Cohort: Mean Change From Baseline in Total Score on the Impact of Weight on Quality of Life-Kids (IWQOL-Kids)
Zeitfenster: Baseline, after approximately 52 Weeks on a Therapeutic Regimen (up to approximately 60 weeks)
The IWQOL-Kids (administered to participants between the ages of 11 and <18 years) is a validated 27-item self-report measure of weight-related quality of life for youth. It provided a total score inclusive of 4 domains: physical comfort, body esteem, social life, and family relations. Results below represent the total score, which is rated on a scale from 0 (worst) to 100 (best), with higher scores indicating better levels of functioning.
