A Study of Gastrointestinal Emptying Time in Adult Participants With Migraine Before and After Start of a mAb CGRP Antagonist

Eli Lilly and Company65 enrolled

Overview

The purpose of this study is to measure the gastrointestinal emptying time using the wireless motility capsule (WMC) technology (FDA approved SmartPill™) in adult participants with migraine who are taking a monoclonal antibody (mAb) calcitonin gene-related peptide (CGRP) antagonist called galcanezumab or erenumab.

Outcomes

Primary Outcomes

Change From Baseline in Colonic Transit Time (CTT) at Week 2

Least squares (LS) mean change from baseline was calculated using analysis of covariance (ANCOVA) model with categorical effects of treatment, pooled investigative site, Body mass index (BMI) category (\<30kg/m2, ≥30 kg/m2) and baseline migraine frequency (\<8 migraine headache days, ≥8 migraine headache days) as well as the continuous baseline CTT (hours). A negative change from baseline indicates a decrease in CTT and a positive change from baseline indicate an increase in CTT.

Time frame: Baseline, Week 2

Secondary Outcomes

Change From Baseline in Whole Gut Transit Time (WGTT) at Week 2

Least squares (LS) mean change from baseline was calculated using ANCOVA model with categorical effects of treatment, pooled investigative site, Body mass index (BMI) category (\<30kg/m2, ≥30 kg/m2) and baseline migraine frequency (\<8 migraine headache days, ≥8 migraine headache days) as well as the continuous baseline WGTT (hours). A negative change from baseline indicates a decrease in WGTT and a positive change from baseline indicate an increase in WGTT.

Time frame: Baseline, Week 2

Change From Baseline in Gastric Emptying Time (GET) at Week 2

Least squares (LS) mean change from baseline was calculated using ANCOVA model with categorical effects of treatment, pooled investigative site, Body mass index (BMI) category (\<30kg/m2, ≥30 kg/m2) and baseline migraine frequency (\<8 migraine headache days, ≥8 migraine headache days) as well as the continuous baseline GET (hours). A negative change from baseline indicates a decrease in GET and a positive change from baseline indicate an increase in GET.

Time frame: Baseline, Week 2

Change From Baseline in Small Intestine Bowel Transit Time (SBTT) at Week 2

Least squares (LS) mean change from baseline was calculated using ANCOVA model with categorical effects of treatment, pooled investigative site, Body mass index (BMI) category (\<30kg/m2, ≥30 kg/m2) and baseline migraine frequency (\<8 migraine headache days, ≥8 migraine headache days) as well as the continuous baseline SBTT (hours). A negative change from baseline indicates a decrease in SBTT and a positive change from baseline indicate an increase in SBTT.

Change From Baseline in Combined Small and Large Intestine Bowel Transit Time (SLBTT) at Week 2

Least squares (LS) mean change from baseline was calculated using ANCOVA model with categorical effects of treatment, pooled investigative site, Body mass index (BMI) category (\<30kg/m2, ≥30 kg/m2) and baseline migraine frequency (\<8 migraine headache days, ≥8 migraine headache days) as well as the continuous baseline SLBTT (hours). A negative change from baseline indicates a decrease in SLBTT and a positive change from baseline indicate an increase in SLBTT.

Time frame: Baseline, Week 2

Change From Baseline in Motility Index by Quartile in the Colon at Week 2

Motility index (MI) is a calculated outcome, based on the formula: In (Number of contractions x Σpressure amplitudes +1) where ln = natural logorithm, Σ = Sum. Least squares (LS) mean change from baseline was calculated using ANCOVA model with categorical effects of treatment, pooled investigative site, Body mass index (BMI) category (\<30kg/m2, ≥30 kg/m2) and baseline migraine frequency (\<8 migraine headache days, ≥8 migraine headache days) as well as the continuous baseline MI. A negative change from baseline indicates a decrease in colonic contractions or pressure or both, and a positive change from baseline indicates an increase in colonic contractions or pressure or both.

Change From Baseline in Gastrointestinal (GI) Symptom Rating Scale (GSRS) at Weeks 2 and 4

GSRS is a validated 15-item questionnaire that evaluates the common symptoms of GI disorders. It has five subscales: abdominal pain (abdominal pain, hunger pains, nausea), reflux (heartburn, acid reflux), indigestion (rumbling, bloating, belching, and increased flatus/breaking wind), constipation (constipation, hard stools, and sensation of not completely emptying the bowels), and diarrhea (diarrhea, loose stools, urgent need to have a bowel movement) syndromes. Subscale scores range from 1 to 7. Higher scores indicate greater severity of symptoms. LS mean change from baseline was calculated using mixed effects model for repeated measures (MMRM) with fixed categorical effects of treatment, pooled investigative site, BMI category (\<30kg/m2, ≥30 kg/m2), baseline migraine frequency (\<8 migraine headache days, ≥8 migraine headache days), week, and treatment-by-week interaction, as well as the continuous fixed covariates of baseline value and baseline-by-week interaction.

Time frame: Baseline, Week 2, Week 4

Change From Baseline in Bristol Stool Form Scale (BSFS) at Weeks 2 and 4

The BSFS is a 7-point ordinal scale which classifies the type of bowel movement based on the appearance of stool. Score 1, 2 indicate constipation (harder stools); 6, 7 indicate diarrhea (loose/liquid stools ); 3 to 5 are considered normal. A better score would trend toward the middle of the scale (3 to 5), while scores at either end of the scale correspond to worse outcomes. LS mean change from baseline was calculated using mixed effects model for repeated measures (MMRM) with fixed categorical effects of treatment, pooled investigative site, BMI category (\<30kg/m2, ≥30 kg/m2), baseline migraine frequency (\<8 migraine headache days, ≥8 migraine headache days), week, and treatment-by-week interaction, as well as the continuous fixed covariates of baseline value and baseline-by-week interaction.

Time frame: Baseline, Week 2, Week 4

Change From Baseline in the Weekly Spontaneous Bowel Movements (SBMs) at Weeks 2 and 4

Weekly SBM is the number of spontaneous (un-aided by laxatives, enemas, or suppositories) bowel movements that a participant has had in the past 7 days. LS mean change from baseline was calculated using mixed effects model for repeated measures (MMRM) with fixed categorical effects of treatment, pooled investigative site, BMI category (\<30kg/m2, ≥30 kg/m2), baseline migraine frequency (\<8 migraine headache days, ≥8 migraine headache days), week, and treatment-by-week interaction, as well as the continuous fixed covariates of baseline value and baseline-by-week interaction. A negative change from baseline indicates a decrease in weekly SBMs, and a positive change from baseline indicates an increase in weekly SBMs.
