Portola Pharmaceuticals first submitted the biologics license application BLA for andexanet alfa in December N Engl J Med Dec 1 Older patients with apiaban untreated disease had better outcomes with ibrutinib than with chemo-immunotherapy.
For additional information on andexanet alfa, visit https: The median duration of follow-up was 1. The rate of the primary outcome was 1.
Andexanet alfa is a modified human factor Xa molecule that acts as a decoy nemm target and sequester both oral and injectable factor Xa inhibitors in the blood. No between-group differences were seen in the rates of adverse events and deaths. Ravulizumab was noninferior to eculizumab in both previously treated and apixabxn patients.
The trial was designed to test for noninferiority, with key secondary objectives of testing for superiority with respect to the primary outcome and to the rates of major bleeding and death from any cause.
DOACs appear to be as effective as LMWH and are more acceptable to patients, but they pose similar risks for bleeding and should be used cautiously in those with gastrointestinal malignancies, renal impairment, or thrombocytopenia.
How Effective Are Guidelines? The rate of major bleeding was 2.
Comment Patients with active malignancies are at risk for VTE but do not always receive prophylactic anticoagulants because of concerns apixabaj bleeding, need for injections, and cost.
N Engl J Med Dec 13 At 23 years of follow-up, life expectancy was nearly 3 years longer with prostatectomy than with watchful waiting. Andexanet alfa is approved for use in patients treated with rivaroxaban or apixaban when apixabxn of anticoagulation is needed due to life-threatening or uncontrolled bleeding. Whether direct oral anticoagulants DOACs would be safe and effective for this indication is unclear. Apixaban to prevent venous thromboembolism in patients with cancer.
Gradishar, MD Highlights of the latest research. At 23 years of follow-up, life expectancy was nearly 3 years longer with prostatectomy than with watchful waiting. N Engl J Med Dec 4. With its first BLA submission, Portola was seeking approval for andexanet alfa as a reversal agent for apixbaan anticoagulated with an oral or injectable factor Xa inhibitor—apixaban, rivaroxaban, zpixaban, or enoxaparin—who experience serious uncontrolled or life-threatening bleeding or who require urgent or emergency surgery.

About andexanet alfa Andexanet alfa is a modified human factor Xa molecule that acts as a decoy to target and sequester both oral and injectable factor Xa inhibitors in the blood.
VTE was less frequent in patients assigned to apixaban versus placebo 4. Results from both studies were published in NEJM in Carrier M et al. N Engl J Med. N Engl J Med Dec 4 Venous thromboembolism occurred less frequently with the direct oral anticoagulant apixaban than with placebo.
Patients with active malignancies are at risk for VTE but do not always receive prophylactic anticoagulants because of concerns about bleeding, need for injections, and cost. National Comprehensive Cancer Network guidelines for multigene panel testing miss nearly half of patients with actionable variants.
FDA approves antidote for factor Xa inhibitors
Once bound, the factor Xa inhibitors are unable to bind to and inhibit native factor Xa, thus potentially allowing for the restoration of normal hemostatic processes. This study is scheduled to start inwith results expected to be available in N Engl J Med Dec 4; [e-pub]. Forty percent of patients with relapsed or refractory disease achieved complete remission.
N Engl J Med Dec 1. N Engl J Med Dec 1 Forty percent of patients with relapsed or refractory disease achieved complete remission. Please register or login here. Blood Dec 3, Kulasekararaj AG et al. J Clin Oncol Dec 7. The FDA had already granted andexanet alfa orphan drug designation earlier in and breakthrough therapy designation in Vitamin K antagonists are highly effective in preventing stroke in patients with atrial fibrillation but have several limitations.
Blood Dec 3. These trials were designed to evaluate the safety and efficacy of andexanet alfa in reversing the anticoagulant activity of rivaroxaban and apixaban in healthy volunteers.
Apixaban versus warfarin in patients with atrial fibrillation.
N Engl J Med Dec Continued FDA approval of andexanet alfa may be contingent upon post-marketing study results to demonstrate an improvement in hemostasis in patients taking rivaroxaban or apixaban who require reversal of anticoagulation.
In patients with atrial fibrillation, apixaban was superior to warfarin in preventing stroke or systemic embolism, caused less bleeding, and resulted in lower mortality.
In this randomized, double-blind trial, we compared nejn at a dose of 5 mg twice daily with warfarin target international normalized ratio, 2. Apixaban is a novel oral direct factor Xa inhibitor that has been shown to reduce the risk of stroke in a similar population in comparison with aspirin.
Apixaban versus warfarin in patients with atrial fibrillation.
A broader commercial launch of andexanet alfa is anticipated in earlydependent upon FDA approval of the generation 2 apiaxban process. This time, the company sought approval of the drug only for patients on apixaban or rivaroxaban who are experiencing uncontrolled or life-threatening bleeding. The rate of hemorrhagic stroke was 0.
Expert Opin Investig Apixabxn. Apixaban or placebo was given within 24 hours of starting chemotherapy and continued for 6 months.
The post-marketing requirement is a trial in which patients will be randomized to receive either andexanet alfa or usual care.
Major bleeding occurred more often with apixaban 3.
