AMPLIFY Post-Hoc Early Time Course Analysis Evaluated Recurrent Venous Thromboembolism (VTE), VTE-Related Death and Major Bleeding in Deep Vein Thrombosis and Pulmonary Embolism Patients Treated with Eliquis (apixaban) or Conventional Therapy

OREANDA-NEWS. December 11, 2015. Bristol-Myers Squibb Company (NYSE:BMY) and Pfizer Inc. (NYSE:PFE) today announced results from a post-hoc early time course subanalysis of the Phase 3 AMPLIFY (Apixaban for the Initial Management of Pulmonary Embolism and Deep Vein Thrombosis as First-Line Therapy) trial. The subanalysis demonstrated Eliquis (apixaban) was comparable to conventional therapy (subcutaneous enoxaparin overlapped and followed by oral warfarin dose-adjusted to an international normalized ratio of 2.0 to 3.0) in recurrent VTE and VTE-related death with significantly less major bleeding during the first 7, 21 and 90 days after starting treatment. These data were published in Thrombosis and Haemostasis.

“For the millions of patients worldwide who experience VTE, the risks of recurrence and major bleeding are highest during the first few weeks of anticoagulant therapy,” said Giancarlo Agnelli, M.D., Professor of Internal Medicine at the University of Perugia, Italy, Director of the Department of Internal and Cardiovascular Medicine and Stroke-Unit at the University Hospital in Perugia, Italy, chair of the AMPLIFY Steering Committee, and co-author of the publication. “These findings indicate that the favorable benefit-to-risk profile of Eliquis was demonstrated early during treatment for VTE, including the use of a higher Eliquis dose of 10 mg twice daily for the initial seven days.”

The results of the subanalyses at each pre-specified time interval were consistent with the overall results of the AMPLIFY trial at 6 months, which demonstrated non-inferiority of Eliquis versus conventional therapy in the primary efficacy endpoint of recurrent VTE and VTE-related death, and superiority in the primary safety endpoint by showing significantly fewer major bleeding events, with a 69 percent relative risk reduction (RRR) (absolute risk reduction [ARR] of 1.1 percentage points [95 percent CI, -1.7 to -0.6]) compared to conventional therapy.

In this post-hoc early time course subanalysis, recurrent VTE and VTE-related death at 7, 21, and 90 days after starting treatment occurred in 18 (0.7 percent), 29 (1.1 percent), and 46 (1.8 percent), patients who were given Eliquis, respectively, and in 23 (0.9 percent), 35 (1.3 percent), and 58 (2.2 percent) patients given conventional therapy, respectively. Outcomes at each time point were similar in patients by index event (deep vein thrombosis (DVT) alone or pulmonary embolism (PE) with or without DVT) and were consistent with the results for the entire study period. Major bleeding at the corresponding time points occurred in 3 (0.1 percent), 5 (0.2 percent), and 11 (0.4 percent) patients, who received Eliquis, respectively, and in 16 (0.6 percent), 26 (1.0 percent), and 38 (1.4 percent) patients given conventional therapy, respectively. Eliquis was non-inferior to conventional therapy in recurrent VTE and VTE-related death at each time point analyzed, with no excess of early recurrences; and patients treated with Eliquis were less likely to have major bleeding early in the course of treatment than those treated with conventional therapy.

The AMPLIFY trial was a double-blind, randomized, multicenter study that compared the efficacy and safety of Eliquis (at a dose of 10 mg orally twice daily for seven days, followed by 5 mg orally twice daily for six months) with those of conventional therapy in 5,395 patients with symptomatic proximal DVT or symptomatic PE with or without DVT. The primary efficacy outcome was the incidence of the adjudicated composite of recurrent symptomatic VTE or death related to VTE that occurred by the end of the treatment period. The primary safety outcome was adjudicated major bleeding that occurred by the end of the treatment period.

For this subanalysis, efficacy and safety outcomes were analyzed for days 7, 21, and 90 after randomization, substratified for the index event (DVT alone, or PE with or without DVT).

About Venous Thromboembolism

Venous thromboembolism, or VTE, encompasses two serious conditions: deep vein thrombosis (DVT), a blood clot in a vein, usually in the lower leg, thigh or pelvis, which partially or totally blocks the flow of blood; and pulmonary embolism (PE), a potentially life-threatening condition in which a blood clot blocks blood vessels in the lungs. Estimates suggest that the number of adults in the U.S. with VTE is projected to nearly double from 0.95 million in 2006 to 1.82 million in 2050. Approximately one million patients in the E.U. are diagnosed with VTE every year. Once a VTE has occurred, up to 11 percent of people may have a VTE reoccurrence, which could potentially be fatal.

About Eliquis

Eliquis (apixaban) is an oral selective Factor Xa inhibitor. By inhibiting Factor Xa, a key blood clotting protein, Eliquis decreases thrombin generation and blood clot formation. Eliquis is approved for multiple indications in the U.S. based on efficacy and safety data from seven Phase 3 clinical trials. Eliquis is a prescription medicine indicated to reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation (NVAF); for the prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE), in patients who have undergone hip or knee replacement surgery; for the treatment of DVT and PE; and to reduce the risk of recurrent DVT and PE, following initial therapy.

ELIQUIS Important Safety Information and Indications

CONTRAINDICATIONS

• Active pathological bleeding
• Severe hypersensitivity reaction to ELIQUIS (e.g., anaphylactic reactions)

WARNINGS AND PRECAUTIONS

• Increased Risk of Thrombotic Events after Premature Discontinuation: Premature discontinuation of any oral anticoagulant, including ELIQUIS, in the absence of adequate alternative anticoagulation increases the risk of thrombotic events. An increased rate of stroke was observed during the transition from ELIQUIS to warfarin in clinical trials in atrial fibrillation patients. If ELIQUIS is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant.
• Bleeding Risk: ELIQUIS increases the risk of bleeding and can cause serious, potentially fatal, bleeding.
  • Concomitant use of drugs affecting hemostasis increases the risk of bleeding, including aspirin and other antiplatelet agents, other anticoagulants, heparin, thrombolytic agents, SSRIs, SNRIs, and NSAIDs.
  • Advise patients of signs and symptoms of blood loss and to report them immediately or go to an emergency room. Discontinue ELIQUIS in patients with active pathological hemorrhage.
  • There is no established way to reverse the anticoagulant effect of apixaban, which can be expected to persist for at least 24 hours after the last dose (i.e., about two half-lives). A specific antidote for ELIQUIS is not available.
• Spinal/Epidural Anesthesia or Puncture: Patients treated with ELIQUIS undergoing spinal/epidural anesthesia or puncture may develop an epidural or spinal hematoma which can result in long-term or permanent paralysis.

The risk of these events may be increased by the postoperative use of indwelling epidural catheters or the concomitant use of medicinal products affecting hemostasis. Indwelling epidural or intrathecal catheters should not be removed earlier than 24 hours after the last administration of ELIQUIS. The next dose of ELIQUIS should not be administered earlier than 5 hours after the removal of the catheter. The risk may also be increased by traumatic or repeated epidural or spinal puncture. If traumatic puncture occurs, delay the administration of ELIQUIS for 48 hours.

Monitor patients frequently and if neurological compromise is noted, urgent diagnosis and treatment is necessary. Physicians should consider the potential benefit versus the risk of neuraxial intervention in ELIQUIS patients.

• Prosthetic Heart Valves: The safety and efficacy of ELIQUIS have not been studied in patients with prosthetic heart valves and is not recommended in these patients.
• Acute PE in Hemodynamically Unstable Patients or Patients who Require Thrombolysis or Pulmonary Embolectomy: Initiation of ELIQUIS is not recommended as an alternative to unfractionated heparin for the initial treatment of patients with PE who present with hemodynamic instability or who may receive thrombolysis or pulmonary embolectomy.

ADVERSE REACTIONS

• The most common and most serious adverse reactions reported with ELIQUIS were related to bleeding.

TEMPORARY INTERRUPTION FOR SURGERY AND OTHER INTERVENTIONS

• ELIQUIS should be discontinued at least 48 hours prior to elective surgery or invasive procedures with a moderate or high risk of unacceptable or clinically significant bleeding. ELIQUIS should be discontinued at least 24 hours prior to elective surgery or invasive procedures with a low risk of bleeding or where the bleeding would be noncritical in location and easily controlled. Bridging anticoagulation during the 24 to 48 hours after stopping ELIQUIS and prior to the intervention is not generally required. ELIQUIS should be restarted after the surgical or other procedures as soon as adequate hemostasis has been established.

DRUG INTERACTIONS

• Strong Dual Inhibitors of CYP3A4 and P-gp: Inhibitors of cytochrome P450 3A4 (CYP3A4) and P-glycoprotein (P-gp) increase exposure to apixaban and increase the risk of bleeding. For patients receiving ELIQUIS doses of 5 mg or 10 mg twice daily, reduce the dose of ELIQUIS by 50% when ELIQUIS is coadministered with drugs that are strong dual inhibitors of CYP3A4 and P-gp (e.g., ketoconazole, itraconazole, ritonavir, or clarithromycin). In patients already taking 2.5 mg twice daily, avoid coadministration of ELIQUIS with strong dual inhibitors of CYP3A4 and P-gp.
• Strong Dual Inducers of CYP3A4 and P-gp: Avoid concomitant use of ELIQUIS with strong dual inducers of CYP3A4 and P-gp (e.g., rifampin, carbamazepine, phenytoin, St. John’s wort) because such drugs will decrease exposure to apixaban and increase the risk of stroke and other thromboembolic events.
• Anticoagulants and Antiplatelet Agents: Coadministration of antiplatelet agents, fibrinolytics, heparin, aspirin, and chronic NSAID use increases the risk of bleeding. APPRAISE-2, a placebo-controlled clinical trial of apixaban in high-risk post-acute coronary syndrome patients treated with aspirin or the combination of aspirin and clopidogrel, was terminated early due to a higher rate of bleeding with apixaban compared to placebo.

PREGNANCY CATEGORY B

• There are no adequate and well-controlled studies of ELIQUIS in pregnant women. Treatment is likely to increase the risk of hemorrhage during pregnancy and delivery. ELIQUIS should be used during pregnancy only if the potential benefit outweighs the potential risk to the mother and fetus.
