Laquinimod Fails For Multiple Sclerosis
If you haven't been reading carefully, you might have had trouble figuring out Teva's oral therapy for multiple sclerosis, laquinimod. After all, earlier this year, the company was blowing the horn for the compound at neurology meetings, touting how safe and effective it was, its advantages over existing therapies, and its potential in the market. You'd hardly know that the compound actually didn't perform as well as many people were hoping. And of course, that very article does mention, near the end, that the company was going to have some more results later in the year. . .
. . .and that day has arrived. Unfortunately. Laquinimod missed its primary endpoint of reducing relapses in MS patients, and unless Teva and its
Israeli Swedish partner company (Active Biotech) have some real surprises to unveil, you'd have to presume that the compound is dead. Or if not dead, destined to never make much of an impact in the market, for sure. This program has had a long history, with an earlier version of the structure (roquinimex) running into severe cardiovascular issues ten or twelve years ago.
Teva is a huge player in the generic world, and in recent years has been trying to break into the research end of the drug business. (Their first was Copaxone (glatiramer acetate), also for MS, a compound with a tangled history). Enjoy the experience, guys. If you're used to dealing with compounds whose value has already been proven, this sort of thing must come as even more of a shock than usual.
