New migraine preventative drugs

They are apparently making good progress on new drugs that specifically target migraines (as opposed to most preventatives which were all developed for other diseases).   Maybe 5 years out to hit the market. I guess it's something...

That link looks like it's the study on cholic and migraines

Link corrected. Sorry for the confusion.

Would someone be willing to quote part/all of this? I'm too tired/aura-y to want to create an account right now, but would love to see even the synopsis, if someone's willing.

Sure thing.  The basic points are:

1.  Something called the "calcitonin gene-related peptide" has been shown to increase during migraine attacks and decreases again once the migraine is over.

2.  The possible drugs would involve antibodies, in other words they would attack the CGRP pathway meaning a decrease in CGRP.

3.  It will be at least 5 years before any drug of this nature will be approved by the FDA.

4.  This would be the first medication(s) developed to prevent migraines.  As migrainegirl said, all other preventatives were actually made for other conditions, hence their poor success rate.

5.  There seem to be several drugs in the works.  Some mop up excess CGRP and some bind to the receptor disabling it.

6.  Trials so far show that patients receiving the real drug were more likely to have fewer migraines versus those receiving a placebo... notably, 41% receiving the real drug had a 100% reduction in migraines after 9 weeks, versus 17% of the placebo takers.  There are other trials mentioned as well.  All trials successfully showed that the real drug worked better than a placebo.

7.  Adverse events reported were upper respiratory tract infections, injection site pain, neck pain, abdominal pain, dizziness, injection site erythema, rash, hypertension, and pain in extremities, although it doesn't say how common the adverse events were.

Thank you!
