Frequently asked questions about Lamotrigine

What is Lamotrigine?

Lamotrigine is a small molecule drug developed by Dr. Reddy's Laboratories Ltd. It is being studied in Phase 1 clinical development. The specific therapeutic indication for this program is undisclosed, and the work falls within a general therapeutic area rather than a named disease category.

What does Lamotrigine target?

Lamotrigine targets the sodium channel proteins SCN1A, SCN5A, SCN4A, SCN7A, SCN2A, and SCN9A. It acts as a blocker at these targets. By blocking these sodium channels, the drug modulates the ion channel activity associated with this target class.

Who makes Lamotrigine?

Lamotrigine is developed by Dr. Reddy's Laboratories Ltd, which trades under the ticker RDY. The company is the sponsor behind the clinical program for this asset.

What phase is Lamotrigine in?

Lamotrigine is in Phase 1 clinical development. It is an investigational drug and has not been approved. Eight trials have been completed and none are currently active, with a total of 284 participants enrolled across the program.

What clinical trials is Lamotrigine in?

Completed Phase 1 trials include NCT01888757 and NCT01888731, both bioequivalence studies of 50 mg extended-release tablets in healthy male volunteers in India, plus NCT01888263 and NCT01888250, which tested 200 mg extended-release tablets under fed and fasting conditions.

How were the Lamotrigine trials designed?

The Lamotrigine trials were randomized and active controlled, though not double blind. They enrolled healthy adult male volunteers aged 18 years and older in India, and none of the studies used biomarker-based patient selection.
