Using roflumilast with TMS to enhance brain plasticity

PDE4 Inhibition and Theta-burst Stimulation Transcranial Magnetic Stimulation Motor Plasticity: a Randomized Placebo-controlled Single-blind Crossover Study

Phase 1 Interventional University of Calgary · NCT06457191

This study is testing if a medication called roflumilast can boost brain function when used with a treatment called rTMS in healthy people.

What this trial studies

This study investigates the effects of roflumilast, a medication that targets intracellular regulation of synaptic plasticity, when combined with repetitive transcranial magnetic stimulation (rTMS) in healthy individuals. It employs a randomized, placebo-controlled, single-blind crossover design to assess the impact of this combination on corticospinal excitability. Participants will undergo screening to determine eligibility and will be randomly assigned to receive either the medication or placebo before undergoing TMS. The study aims to quantify the effects of this intervention on brain function and assess any side effects experienced by participants.

Who should consider this trial

Good fit: Ideal candidates are healthy individuals aged 18-60 with no chronic medical conditions.

Not a fit: Patients with chronic medical conditions, psychiatric concerns, or those taking medications that interact with roflumilast may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved treatments for mental illnesses by enhancing brain plasticity.

How similar studies have performed: While the combination of pharmacological agents with TMS is being explored, this specific approach targeting intracellular mechanisms is novel and has not been extensively tested.
