The Latest Capecitabine Lonafarnib Is Twice The Fun

uires no coagulation monitoringand could be given when every day. It prolongs the activated partialthromboplastin time, but its effect isn't dose-linear andit Lonafarnib isn't suitable to get a precise quantification with the anticoagulanteffect. At the very least 80% of dabigatran is excreted unchangedvia the kidneys; therefore, the drug is contraindicatedin patients with serious renal failure, with a creatinineclearance less than 30 mL/min. Dabigatran etexilatehas been already licensed within the European Union andin Canada for the prevention of VTE in patients undergoinghip- and knee-replacement surgery, with a recommendeddose of 220 mg when every day for all patients but those withmoderate renal insufficiencyand the elderly, forwhom the advisable dose is 150 mg when every day.A dose reduction is also advisable for patients on amiodaronetreatment.
Dabigatran etexilate is at present undergoing a large phaseIII program for the evaluation of its efficacy and safety inthe acute therapy end within the secondary prevention of VTE.The RE-COVER trial Lonafarnib evaluated Capecitabine dabigatran for 6 month treatmentof acute symptomatic VTE, while the RE-MEDY andthe RE-SONATE trials are recruiting patients who have beensuccessfully treated with normal doses of an approved anticoagulantfor three to six months or who have completed6 to 18 months of therapy with vitamin K antagonist forconfirmed acute symptomatic VTE, respectively. The RECOVERstudy was published at the end of 2009. Patientswith acute VTE, DVT and/or PE, who were initially treatedwith parenteral anticoagulants, were randomized to receivedabigatran etexilate, administered at a dose of 150 mg twicedaily, or dose adjusted warfarin.
The principal outcome with the study wasthe 6-month incidence of recurrent symptomatic, objectivelyconfirmed VTE and related deaths. Thirty with the 1,274dabigatran patients, NSCLC as compared with 27 with the 1,265warfarin patients, had recurrent VTE. The difference in riskwas 0.4 percentage points. The hazard ratio with dabigatran was 1.10. Main bleeding episodes occurredin 20dabigatran patients and in 24warfarin patients, and episodes of any bleeding were observedin 205dabigatran patients and in 277warfarinpatients.2. Direct element Xa inhibitorsRivaroxaban is the initial of this new class of drugs. It isa potent and selective oral Element Xa inhibitor with a particularchemical structure in its active-site binding region thatplays a function within the oral absorption with the drug, with a relativelyhigh bioavailabity.
Plasma levels of thedrug peak immediately after 3 to 4 hours, with a mean half-life rangingfrom 5 to 9 hours in young people, and from 11 to13 hours within the elderly. The main route of excretionis renal, but the drug is also expelled by way of the faecal/biliarroute. Rivaroxaban Capecitabine could be administered at a fixed dosein any patient and doesn't need laboratory monitoring.Also rivaroxaban has been licensed within the European Unionand in Canada for the prevention of VTE in patients undergoinghip- and knee-replacement surgery, with a recommendeddose of 10 mg when every day.Two phase II, dose-finding studies compared rivaroxabanadministered at total every day doses ranging from 20 mg to60 mg with normal therapy with LMWH followed by oralvitamin K antagonists.
According to the optimistic resultsof these studies, the following doses were selected for furtherinvestigation within the three phase III clinical Lonafarnib trials aimed toassess the acute phase as well as the long term therapy of DVTand PE: 15 mg bid for 3 weeks followedby 20 mg qd within the ongoing Einstein DVT and EinsteinPE studies, in which patients with objectively confirmed,symptomatic DVT or PE are randomized to therapy withrivaroxaban alone or with LMWH and vitamin K antagonistsfor a total period of 3 to 12 months, and 20 mg qd in theEinstein Extension study, in which patients who had completed6 to 12 months of anticoagulant therapy with eithervitamin K antagonists or rivaroxabanafter an acute episode of VTE wererandomized to rivaroxaban or placebo for additional 6 to12 months.
The Einstein Extension study is already completed,as well as the outcomes have been presented at the AmericanSociety of Hematology meeting in December 2009. Inthis randomised, double blind, placebo-controlled study, theprimary efficacy outcome was the recurrence of symptomaticVTE as well as the principal safety outcome was the occurrenceof key bleeding. Throughout therapy, symptomatic Capecitabine recurrentVTE events occurred in 7.1% patients treated with placeboand in 1.3% patients treated with rivaroxaban. Right after stoppingthe study medication, 1.0% symptomatic recurrent VTEevents occurred in both groups during the a single month observationalperiod of adhere to up. No key bleeding eventswere documented within the group of patients treated with placebo,4major bleeding events occurred within the rivaroxabangroup. None of these bleeding events werefatal or occurred inside a vital site. Clinically relevant non-majorbleeding occurred in 1.2% and in 5.4% patients randomizedto placebo and rivaroxaban, respectively. Twopatients within the placebo group and 1patient
