Subject: For Wiki-Mon, Phase II trial for GIST: HSP90 Inhibitor BIIB021

The trial sites include NYC (I assume MSKCC) and Rochester MN (I assume the Mayo clinic). Contact is through the trial sponsor, Biogen: oncologyclinicaltrials@biogenidec.com

Biogen has a HSP90 drug called CNF2024. I DO NOT KNOW if BIIB021 is a different drug than CNF2024???? Don't know, but I bring it up because Herb Flom tried CNF2024 and Kathy wrote about it in the Wiki. There many different intestigational HSP90 inhibitors out there. HSP90 is a very drug-able target. Some inhibitors are based on the antibiotic geldanamycin, and others are smaller synthetic molecules that mimic the shape and chemical characteristics of the ATP binding pocket on HSP90.

For the new people, HSP90 is a chaperone that facilitates the actions of mutated KIT in GIST. When HSP90 is blocked by an inhibiting drug, then the mutated KIT proteins in GIST are destroyed at a faster rate...

Marina,

I'm going to participate in this trial. The insurance cleared and MSKCC is setting up my pre-tests.

You're right on all counts- It is at both MSKCC and the Mayo Clinic. It is CNF2024, renamed after Biogen Idec bought out the prior drug company.

It's a PET Scan intensive trial.

Kerry,

The metasteses from GIST can go pretty much anywhere as the disease advances. I'm finishing up a 10 day regimen of radiation for several sites in and/or on my back muscles and bones. There are also sites in my lungs. I have about a half dozen sites in my leg muscles, both calf and thigh, and one that I can feel and move around with my fingers on my left shoulder. None of the leg or shoulder sites bother me but they're easy to see on CAT and PET scans.

I was in a trial at Fox Chase for AMN 107 and it didn't do anything for me either.

Nexavar is pretty nasty stuff. It gave me high blood pressure, lowered my appetite, I lost weight quickly, developed thick callouses on the soles of my feet and had very serious bouts of diarrhea. I'm surprised the insurance company has a problem with a prescription for it since it's FDA approved for kidney cancer. You're just getting it off-label.

I'll be returning to MSKCC for a phase 2 trial of BIIB021, (NCT00618319 Clinical.trials.gov identifier) in 2 weeks. They insisted that I get the back sites irradiated before I could start the trial.

I hope this helps, Good luck with your husbands fight.

Dave
