The future of medical marijuana research is uncertain, though looks promising. In late July 1999, the FDA informed Dr. Ethan Russo, University of Montana, that his MAPS-supported protocol to study marijuana in the treatment of migraines was fully approved. However, the protocol was placed on hold until NIDA decides if it will supply the marijuana. NIDA's new policy is to submit FDA-approved projects to a special Public Health Service (PHS) review before agreeing to sell marijuana for a yet-to-be-determined price to non-government funded projects. Whether this PHS review will be conducted in a fair and timely manner remains to be seen.
Tuesday July 27, 1999 Subject: Cannabis in Migraine Treatment Project Close to FDA Approval
Dear Friends,
Inasmuch as FDA assesses its IND applications in 30 days from receipt, I would expect
similar treatment for this protocol from NIDA. I understand that NIDA has said that a
price for the cannabis will not be available until December 1999, but that should not
delay this process, since I am willing to pay any price that is required for the 200 grams
of cannabis, and 200 grams of acetone-treated cannabis placebo. Thus, I would hope to
hear from NIDA expeditiously as to plans and disposition of the project.
This application process began in early 1997 when FDA refused to review a first protocol
due to lack of an approved supply of cannabis from NIDA. A subsequent application to NIH
for funding was denied. The process repeated itself in 1998 with an FDA refusal, and
subsequent NIH denial of an amended protocol. In 1999, the protocol was submitted a
third time, but received the mandated 30 day review with request for certain
clarifications and supplementation. These were recently returned, and apparently were
sufficient to allow FDA approval pending NIDA cooperation. I am hoping that a "thaw" has
occurred in NIDA philosophy on provision of cannabis for clinical studies. If so, an
additional hurdle will remain in the fundraising for performance of the study. What was
originally envisioned as a simple clinical trial has grown into a budget of some $250,000
to study effects of cannabis, Marinol (synthetic THC), and their placebo equivalents vs.
injected sumatriptan (the current "gold standard") in 40 patients over 5 months. Ethan Russo, MD
