Legato-HD -
paragraph image
LEGATO-HD is a Phase II clinical research trial that will look at the safety of an investigational drug called laquinimod and how it may affect movement, thinking and behaviour compared to placebo (a sugar pill) in people with Huntington’s disease (HD).

Laquinimod is an investigational drug being studied to see if it may have an effect on some of the symptoms of Huntington’s disease. Laquinimod has already been investigated for the treatment of multiple sclerosis (MS) as it acts both on the immune system and within the central nervous system. It has been suggested that day laquinimod may have an effect on the progression of HD. This trial is being conducted to determine if laquinimod helps with the signs and symptoms of HD.

LEGATO-HD is a joint collaboration between the Huntington Study Group (HSG), the European Huntington’s Disease Network (EHDN) and Teva Branded Pharmaceutical Products R&D Inc.
400 people are expected to take part in the LEGATO-HD Study at approximately 36 trial sites across North America and Europe.

Participants will receive laquinimod or placebo in the form of capsules, for 52 weeks (12 months). The trial will last approximately 14 months, which includes: 1 screening visit, 52 weeks of treatment (including 6 clinic visits and 1 telephone call) and 1 follow-up visit.

The LEGATO-HD Study
A randomized, double blind research study to see what effect the investigational drug, laquinimod, has on movement, thinking, and behavior, compared to placebo (a sugar pill), in people with Huntington disease after 52 weeks of receiving either laquinimod or placebo.

What is the LEGATO-HD Study?
The purpose of the LEGATO-HD trial is to see what effect different doses of an investigational drug called laquinimod may have on people with HD. In addition, information will be collected about the safety and possible side effects of laquinimod in people with HD. This is a placebo-controlled trial, with participants randomly assigned to receive one of three different doses of laquinimod, or placebo (sugar pill). Everyone will receive the same number of capsules (3, taken together once a day), and neither participants nor their trial doctors will know to which group they are assigned.
