Clinical Trial Summary

We want to investigate whether an acute administration of hydroxychloroquine sulphate affects hedonic food intake, appetite related sensations and gastrointestinal hormone release in overweight female subjects.

Description:

Intragastric administration of a quinine-solution has shown to decrease hedonic food intake in healthy female volunteers. The effect of a tablet containing hydroxychloroquine sulphate on hedonic food intake in overweight female individuals has not been studied to date. The primary outcome of the current study is to evaluate the effect of hydroxychloroquine sulphate on hedonic food intake, assessed by ad libitum food intake of a chocolate milkshake one hour after dosing. The study is a randomized, placebo-controlled, double blinded cross-over study. Forty overweight females will be recruited. An acute dose of 400 mg hydroxychloroquine sulphate will be administered. Blood samples will be collected at regular time points to measure gastrointestinal hormone release and whole blood glucose levels. Appetite-related sensations will be scored at regular time points on visual analog scales.

• Subject has diabetes.

• Subject has a significant heart, lung, liver or kidney disease.

• Subject has a QT-interval > 450 ms.

• Subject has retinopathy.

• Subject suffers from psoriasis.

• Subject has porphyria.

• Subject shows abnormal eating behavior or has an eating disorder.

• History or current use of drugs that can affect glycaemia, gastrointestinal function, motility or sensitivity or gastric acidity.

• History or current use of centrally acting medication, including antidepressants, antipsychotics and/or benzodiazepines (in the last year before screening visit).

• Subject consumes excessive amounts of alcohol, defined as >14 units per week.

• Subject is currently (defined as within approximately 1 year of the screening visit) a regular or irregular user (including "recreational use") of any illicit drugs (including marijuana) or has a history of drug (including alcohol) abuse. Further, patient is unwilling to refrain from the use of drugs during this study.

• High caffeine intake (> 500 ml coffee daily or equivalent).

• Inability or unwillingness to perform all of the study procedures, or the subject is considered unsuitable in any way by the principal investigator.

• Recent participation (<30 days) or simultaneous participation in another clinical study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The effect of hydroxychloroquine sulphate on hedonic food intake	Hedonic food intake will be assessed using a chocolate milkshake drinking task. Subjects are instructed to drink ad libitum from a chocolate milkshake until fully satiated. The milkshake will be weighted before and after the experiment and 1 g of chocolate milkshake = 1 kcal.	60 min after plaquenil or placebo administration
Secondary	The effect of hydroxychloroquine sulphate on gastrointestinal hormone release	Gastrointestinal hormone release will be measured in plasma samples collected at regular time points to assess the release of ghrelin and motilin.	First sample 10 min prior to administration. Followed by collections every 10 min after administration for a period of one hour. A final blood sample will be collected 30 min after consumption of the chocolate milkshake.
Secondary	The effect of hydroxychloroquine sulphate on glucose	Whole blood glucose levels will be measured at regular time points with a blood glucose meter.	First sample 10 min prior to administration. Followed by collections every 10 min after administration for a period of one hour. A final blood sample will be collected 30 min after consumption of the chocolate milkshake.
Secondary	The effect of hydroxychloroquine sulphate on appetite-related sensations	Hunger, prospective food consumption, satiety, fullness, bloating, belching, cramps and pain will be scored by the subjects on visual analog scales of 100 mm.	All appetite-related sensations will be scored every 10 min for a period of 110 minutes, starting 20 min before plaquenil or placebo administration and ending 90 min after administration..
