Frequently asked questions about Investigational Medicinal Product

What is the Investigational Medicinal Product used for?

The Investigational Medicinal Product is being studied for epilepsy. It is an investigational small molecule developed by GSK plc. A Phase 1 trial evaluated modified release formulations of the drug in healthy adult volunteers with the goal of characterizing its pharmacokinetic performance at steady state.

Who is developing the Investigational Medicinal Product?

GSK plc, which trades under the ticker GSK, is the developer of the Investigational Medicinal Product. The company sponsored the Phase 1 pharmacokinetic study of the drug in epilepsy. GSK plc is the sole company identified as developing this asset.

What phase is the Investigational Medicinal Product in?

The Investigational Medicinal Product is in Phase 1 development. One Phase 1 trial has been completed, and no trials are currently active. The completed study enrolled 36 participants and assessed repeat-dose pharmacokinetics of five modified release formulations compared with an immediate release formulation.

What clinical trial has been conducted with the Investigational Medicinal Product?

The Investigational Medicinal Product was studied in NCT01332513, a completed Phase 1 trial titled an open label, randomised, repeat dose study to assess the pharmacokinetic performance of five modified release formulations at steady state compared to the immediate release formulation. The trial enrolled 36 healthy adult volunteers in the United States.

Is the Investigational Medicinal Product the same as Investigational Medicinal Product (MR1)?

Yes. The Investigational Medicinal Product is also known as Investigational Medicinal Product (MR1). The MR1 designation refers to the modified release formulations evaluated in the Phase 1 pharmacokinetic study. Both names refer to the same GSK plc epilepsy asset in Phase 1 development.

How was the Investigational Medicinal Product studied in its Phase 1 trial?

The Phase 1 trial NCT01332513 was an open label, randomized, controlled, repeat dose study. It compared five modified release formulations of the Investigational Medicinal Product against the immediate release formulation at steady state. The study enrolled 36 healthy volunteers aged 18 years and older in the United States and has been completed.
