comparing 5 year EFS with dasatinib 100 mg once daily and imatinib 400 mg once daily.63 Finally, Studying Interventions for Managing Patients with Chronic Myeloid Leukemia in Chronic Phase: the 5 Year Prospective Cohort Study recently Varespladib has been initiated in patients with newly diagnosed CML CP receiving any BCR ABL inhibitor. Primary objectives include 12 month CCyR rate, initial treatment duration, rate of discontinuation and treatment changes after initial therapy, rates of best response to therapy, and adherence.64 CONCLUSIONS The key goal in treating patients with CML CP is to achieve and maintain clinical remission. Imatinib was successful in treating most patients with untreated CML CP, but resistance, which might result from a multitude of causes, including decreased imatinib plasma concentration and mutations, prevented many from achieving full clinical benefit.
Published data indicated that dasatinib, a compound less susceptible to the major molecular mechanisms of imatinib resistance, was effective in treating patients with clinical resistance to imatinib and was more effective than high dose imatinib in imatinib resistant and intolerant patients. Dasatinib had induced Ivacaftor VX-770 robust CCyRs by 3 months in Phase II, open label studies in newly diagnosed CML CP. The Phase III, open label DASISION study reported superior efficacy for dasatinib 100 mg once daily compared with imatinib 400 mg once daily. Dasatinib induced significantly higher rates of confirmed CCyR and MMR by 12 months compared with imatinib.
Because an early response to therapy, such as achievement of a CCyR within 12 months, was associated with better long term PFS, data obtained to date suggested epigallocatechin 989-51-5 that dasatinib has the potential to improve the long term outcomes for patients with newly diagnosed CML CP and that dasatinib was an effective treatment option. These findings will Gemcitabine 122111-03-9 require confirmation in Phase III, randomized, double blind trials. There were conflicting data regarding rates of myelosuppresion, and it was not clear whether patients treated with dasatinib experienced higher rates of bone marrow depression than patients treated with imatinib. Both dasatinib and nilotinib, another secondgeneration BCR ABL inhibitor, were approved by the FDA and EMA for the treatment of adults with newly diagnosed Ph CML CP, and the current National Comprehensive Cancer Network guidelines include the use of imatinib, dasatinib, and nilotinib as treatment options for patients with newly diagnosed CMLCP.
6 Future randomized trials will determine which newly diagnosed CML patients are most likely to achieve the maximum benefit from early therapy with dasatinib versus other treatment options in patients with newly diagnosed disease.Anticoagulation therapy has been a remarkably stable field of reasoning medicine for more than 50 years. In 1960, Barritt and Jordan published a randomized trial that demonstrated that a regimen of 6 days of intravenous heparin followed by an oral vitamin K antagonist resulted in a marked, significant reduction in fatal and nonfatal recurrent pulmonary embolism.1 Their study even included a simple algorithm for dose adjustment of the vitamin K antagonist based on the prothrombin time.
