Plain English Summary

Background and study aims
Brain cells use certain messengers to communicate which each other, which are called neurotransmitters. Acetylcholine (ACh) is such a neurotransmitter and plays a crucial role in processes such as memory and attention. Importantly, it might have a role in the origin of disorders such as Alzheimer’s disease and/or psychiatric disorders such as schizophrenia. Affecting brain cell communication with certain drugs that target ACh can reliably brings on symptoms in healthy volunteers that are similar to patients suffering from Alzheimer's or schizophrenia. These so-called challenges could potentially be new tools to investigate new drugs that interact with ACh and that could improve the symptoms of Alzheimer's disease or schizophrenia. One of these potential challenge drugs is biperiden, as it induces deficits in memory and attention. In this study the aim is to investigate biperiden administered into a vein (IV) as a challenge drug, so it can later be applied to test new drugs that interact with ACh.

Who can participate?
Healthy volunteers aged between 65 and 80 (inclusive) years old

What does the study involve?
The treatment phase will consist of three identical visits to the clinic during which biperiden or placebo will be administered. These visits will be separated by a period of 7-14 days between administrations. Participants will receive IV biperiden Lactate 2.6 mg over 60 min, IV biperiden Lactate 1.3 mg over 60 min and IV placebo (glucose 5%). During the study safety measures such as measurement of blood pressure, heart rate, breathing rate and ECG will be done. Additionally, two computerized test batteries will be performed several times to test, for example, memory and coordination.

What are the possible benefits and risks of participating?
Biperiden is a registered drug that is prescribed to patients suffering from Parkinson's disease. In addition to cognitive effects, self-limiting and mild dizziness and drowsiness may be observed. All effects will be closely monitored up to 24 hours following biperiden administration. There will be no benefit from participating in this study. However, participation will provide valuable information for future research into dementia.

Scientific titleRandomized, double-blind, placebo-controlled, 3-way cross-over study to characterize the pharmacodynamics and pharmacokinetics of single-dose intravenously administered biperiden in healthy elderly male and female subjects
Study hypothesisIntraveneously administered biperiden will induce transient impairment on cognitive domains such as working memory and sustained attention.
Ethics approval(s)Approved 26/01/2022, Stichting BEBO (Doctor Nassaulaan 10, 9401 HK Assen, The Netherlands; +31 592-405871; info@stbebo.nl), ref: NL80005.056.21
ConditionImproving the cognitive impairment associated with dementia and other neurocognitive disorders
InterventionThe double-blind treatment phase will consist of three identical treatment periods separated by a washout period of 7-14 days between the biperiden/placebo administrations. Admission to the CRU is on the evening of Day -1, study drug administration is on Day 1, and discharge on Day 2.

Study treatments:
IV biperiden Lactate (5 mg/ml) 2.6 mg over 60 min (corresponds to biperiden base 2.0 mg)
IV biperiden Lactate (5 mg/ml) 1.3 mg over 60 min (corresponds to biperiden base 1.0 mg)
IV placebo (glucose 5%) for 60 min

The study will consist of three treatment arms for 12 subjects. Each subject will receive one dose of placebo (glucose 5%) and two doses of IV biperiden Lactate dissolved in glucose 5% (5 mg/ml). Once 2.6 mg biperiden and once 1.3 mg biperiden. The study drug will be administered as a 60-minute continuous IV infusion given on Day 1 of the treatment period.

Subjects will have three treatment occasions separated by 7 to 14 days and one follow-up visit 7 to 14 days after the third treatment visit. Subjects will enter the clinical unit on Day -1 and be discharged on Day 2.

Subjects will be randomized using a 1- or 2-digit subject number. They will be randomized in a consecutive order, starting with the lowest number, in blocks of 4. Subjects will be randomized in such a way that biperiden 2.6 mg will only be administered after the subjects have completed the study day with the 1.3 mg dose. In this way, the effects of the 2.6 mg dose may be tolerated better. The randomization code will be generated using SAS version 9.4 (or a more recent version) by a study-independent, Centre for Human Drug Research (CHDR) statistician. The randomization code will be unblinded/broken and made available for data analysis only after study closure, i.e., when the study has been completed, the protocol deviations determined, and the clinical database declared complete, accurate and locked. The randomization code will be kept strictly confidential. Sealed individual randomization codes, per subject and per treatment, will be placed in a sealed envelope with the label 'emergency decoding envelopes' in a safe cabinet at CHDR.
