Effect of Hydroxychloroquine Sulphate in Healthy Lean Females (PLAQHV)

The Effect of Hydroxychloroquine Sulphate on Hedonic Food Intake, Appetite-related Sensations and Gastrointestinal Hormone Release in Healthy Female Subjects

The effect of an acute administration of hydroxychloroquine sulphate will be investigated on hedonic food intake, appetite related sensations and gastrointestinal hormone release in healthy female subjects.

Study Overview

• Status: Unknown
• Conditions: Obesity
• Intervention / Treatment: Drug: Hydroxychloroquine Sulphate; Drug: Placebo

Detailed 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. Ten healthy lean females will be recruited as a proof of concept, before testing hydroxychloroquine sulphate in overweight female subjects. 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.

Women of non-childbearing potential may be included if surgically sterile (tubal ligation or hysterectomy) or postmenopausal with at least 2 year without spontaneous menses.
• Subject understands the study procedures and agrees to participate in the study by giving written informed consent.

Exclusion Criteria:

• Subject has diabetes.
• Subject has a significant heart, lung, liver or kidney disease.
• Subject has a QT-interval > 450 ms.
• Subject has any history of a neurological disorder.
• Subject has a history of abdominal surgery. Those having undergone a simple appendectomy more than 1 year prior to the screening visit may participate.
• 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.
• Subjects with lactose intolerance.
• Subjects with quinine allergy.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Hydroxychloroquine Sulphate; Plaquenil (hydroxychloroquine sulphate) will be acutely administered per os with 240 ml of water. Two tablets of 200 mg hydroxychloroquine sulphate each will be given.	Drug: Hydroxychloroquine Sulphate; After a stabilization period of 20 min and 10 min after the first blood collection, Plaquenil (Hydroxychloroquine sulfate) will be administered per os (total dose of 400 mg) in a randomized, double-blinded fashion.; Other Names: Plaquenil
PLACEBO_COMPARATOR: Placebo; Two placebo tablets will be acutely administered per os with 240 ml of water.	Drug: Placebo; After a stabilization period of 20 min and 10 min after the first blood collection, Placebo will be administered per os (2 tablets) in a randomized, double-blinded fashion.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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. 1 g of chocolate milkshake = 1 kcal.	60 min after plaquenil or placebo administration

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.
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.
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.
