Guest guest Posted June 7, 2010 Report Share Posted June 7, 2010 Hi all, For those of us who grew up with the discovery of Gleevec, here is an eloquent report by Marina Symcox (a GIST patient reporting from ASCO) on the passing of Gleevec as a treatment for CML. Zavie Zavie (age 72) dxd AUG/99 INF OCT/99 to FEB/00, CHF No meds FEB/00 to JAN/01 Gleevec since MAR/27/01 (400 mg) CCR SEP/01. #102 in Zero Club 2.8 log reduction Sep/05 3.0 log reduction Jan/06 2.9 log reduction Feb/07 3.6 log reduction Sep/08 4.0 log reduction Dec/09 4.4 log reduction Apr/10 e-mail: zmiller@... WSJ news from ASCO: Two Drugs Appear to Surpass Landmark Novartis Leukemia Treatment http://online.wsj.com/article/SB10001424052748704183204575288490590419492.ht ml?mod=J_hps_LEFTWhatsNews The large general ASCO meeting is underway this weekend (American Society of Clinical Oncology). It is kind of like a big trade show--academic science and a whole lot of industry news. Gleevec as the first line of defense treatment for chronic myeloid leukemia is becoming dethroned by newer drugs (nilotinib and dasatinib) that " do it better, " and which have longer patent lives for their companies too. And even though I have known for some time that this " changing of the guard " was underway and inevitable, and while probably it is a sign of progress and better things for patients, it also makes me feel a little nostalgic for it marks the dismantling of the Glory days of Gleevec. And such a day will come for the relationship between Gleevec and GIST too...right now two large phase III trials are grinding away quietly behind scenes comparing Gleevec as the old tried and true first line of defense drug against new drugs (Nilotinib or Mastinib). It seems like yesterday when Gleevec was the miracle news of ASCO 2001.... And there was a time back during WWII when penicillin was a great miracle... As went penicillin, so goes Gleevec, two iconic drugs of their day, surpassed by newer.... " " CHICAGO-Novartis AG's Gleevec is one of the closest things to a miracle drug to come out of the battle against cancer in recent years. But new research suggests two newer drugs are even more effective for the form of leukemia whose treatment Gleevec has transformed. " " " " Bristol-Myers Squibb Co.'s Sprycel and Novartis's Tasigna each were superior to Gleevec in treating people with newly diagnosed chronic myeloid leukemia. The two newer drugs are currently approved to treat patients whose disease persisted after trying Gleevec. " " " " The new studies could help widen the patient populations for both Sprycel and Tasigna if doctors begin choosing them over Gleevec for newly diagnosed patients " " " " But some doctors might still stick with Gleevec until Tasigna and Sprycel can demonstrate a long-term survival advantage over Gleevec. Also, Gleevec could be viewed as a more cost-effective option when the drug loses patent protection and cheaper generic versions become available in coming years. " " " " Gleevec had world-wide sales of $3.9 billion last year. " " " " Both Sprycel and Tasigna are more potent in going after a certain molecular target than Gleevec " " " " There were various side-effects associated with each drug in the studies, such as skin problems and headaches for Tasigna and accumulation of fluid in the chest for Sprycel. But Sawyers, a cancer specialist at the Memorial Sloan-Kettering Cancer Center in New York, wrote in an editorial in the NEJM that all three drugs have " outstanding safety profiles. " " " " " Dr. Sawyers raised the question of whether the new data would render Gleevec " forever enshrined in the history of oncology but no longer useful. " But he said Gleevec may get new life when it goes generic: " With rising pressure to balance cost and efficacy, patients and payers may be forced to select the cheapest among three excellent treatment options. " " " " " Dr. Kantarjian said Sprycel and Tasigna would have to show significant improvement in survival to justify their prices versus generic Gleevec in first-line CML. Pfizer Inc. is developing a similar CML drug, bosutinib, that would compete against the others if it reaches the market. " " Quote Link to comment Share on other sites More sharing options...
