| THOUSAND OAKS, Calif., Sept. 24, 2019 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today announced that the results of a prespecified interim analysis of an open-label, randomized, controlled global multicenter Phase 3 trial (20120215) showed that the primary endpoint of event-free survival was met. The study evaluated the efficacy, safety and tolerability of BLINCYTO® (blinatumomab) compared to conventional consolidation chemotherapy in pediatric patients with high-risk, B-cell acute lymphoblastic leukemia (ALL) at first relapse. Enrollment was terminated early due to encouraging efficacy in the BLINCYTO arm and was based on a recommendation from the Independent Data Monitoring Committee (DMC). Follow up will continue as prescribed per protocol. In addition, a randomized, Phase 3 trial (AALL1331) conducted by the Children’s Oncology Group (COG) using BLINCYTO in pediatric B-cell ALL patients at first relapse has closed to accrual for the high-risk and intermediate risk-arm based on the recommendation of the COG DMC. The DMC closure decision was based on a strong trend towards improved disease-free survival and improved overall survival, markedly lower toxicity, and better minimal residual disease (MRD) clearance for BLINCYTO compared to chemotherapy. The COG DMC recommended that the AALL1331 low-risk group continue to enroll and randomize patients until enrollment goals are reached. AALL1331 is sponsored by the Cancer Therapy Evaulation Program of the National Cancer Institute (NCI), part of the National Institutes of Health, and is conducted by the NCI-funded COG. Amgen provided BLINCYTO for AALL1331 under a Collaborative Research and Development Agreement between the NCI and Amgen. “Considered together, the results of these studies are remarkable. Children and adolescents who relapse with acute lymphoblastic leukemia face a poor prognosis and there remains a need for additional treatment options, particularly for those that are identified as high-risk. These data have the potential to be practice-changing and may provide a treatment approach to prevent further relapse that is superior to chemotherapy,” said David M. Reese, M.D., executive vice president of Research and Development at Amgen. “We look forward to discussing these data with regulatory authorities.” The BLINCYTO adverse events observed in the Phase 3 20120215 and the COG AALL1331 studies were consistent with the known safety profile of BLINCYTO. These interim data will be submitted to a future medical conference and for publication. About the 20120215 Study Study 20120215 is a Phase 3 open-label, multicenter, randomized, controlled trial to evaluate event-free survival after treatment with BLINCYTO compared with standard of care consolidation chemotherapy in pediatric patients with high-risk first relapsed B-cell ALL. Key secondary endpoints included incidence of overall survival and MRD response, AEs, 100-day mortality after alloHSCT, incidence of anti-blinatumomab antibody formation, cumulative incidence of relapse. This is a global study that is being conducted as part of the PIP (Pediatric Investigation Plan) agreed to between Amgen and the EMA. The study is being conducted in Australia and various countries in EU and Latin America. Click here to read about the trial on ClinicalTrials.gov. About the COG AALL1331 Study The COG AALL1331 study is a risk-stratified, randomized, Phase 3 trial of blinatumomab in first relapse of pediatric B-ALL to evaluate disease-free survival (DFS) of high-risk (HR) and intermediate-risk (IR) relapsed B-ALL patients who are randomized following induction block 1 chemotherapy to receive either two intensive chemotherapy blocks or two 5-week blocks of blinatumomab. It also compares the DFS of low risk (LR) relapse B-ALL patients who are randomized following block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab. Key secondary endpoints include overall survival of HR, IR, and LR relapsed B-ALL patients. This is a global study that is being conducted in Australia, Canada, New Zealand and United States.

About BLINCYTO® (blinatumomab) BLINCYTO is a bispecific CD19-directed CD3 T cell engager (BiTE®) antibody construct that binds specifically to CD19 expressed on the surface of cells of B-lineage origin and CD3 expressed on the surface of T cells. BiTE antibody constructs are a type of immunotherapy being investigated for fighting cancer by helping the body’s immune system to detect and target malignant cells. The modified antibodies are designed to engage two different targets simultaneously, thereby juxtaposing T cells (a type of white blood cell capable of killing other cells perceived as threats) to cancer cells. BiTE antibody constructs help place the T cells within reach of the targeted cell, with the intent of allowing T cells to inject toxins and trigger the cancer cell to die (apoptosis). BiTE antibody constructs are currently being investigated for their potential to treat a wide variety of cancers. BLINCYTO was granted breakthrough therapy and priority review designations by the U.S. Food and Drug Administration and is approved in the U.S. for the treatment of:
In the EU, BLINCYTO is indicated as monotherapy for the treatment of:
About BiTE® Technology Bispecific T cell engager (BiTE®) technology is a targeted immuno-oncology platform designed to engage patients’ own T cells to any tumor-specific antigen, activating the cytotoxic potential of T cells to eliminate detectable cancer. BiTE antibody constructs are currently being investigated for their potential to treat a wide variety of cancers. For more information, visit www.biteantibodies.com.

Forward-looking statements involve significant risks and uncertainties, including those discussed below and more fully described in the Securities and Exchange Commission reports filed by Amgen, including our most recent annual report on Form 10-K and any subsequent periodic reports on Form 10-Q and current reports on Form 8-K. Unless otherwise noted, Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise. No forward-looking statement can be guaranteed and actual results may differ materially from those we project. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, preclinical results do not guarantee safe and effective performance of product candidates in humans. The complexity of the human body cannot be perfectly, or sometimes, even adequately modeled by computer or cell culture systems or animal models. The length of time that it takes for us to complete clinical trials and obtain regulatory approval for product marketing has in the past varied and we expect similar variability in the future. Even when clinical trials are successful, regulatory authorities may question the sufficiency for approval of the trial endpoints we have selected. We develop product candidates internally and through licensing collaborations, partnerships and joint ventures. Product candidates that are derived from relationships may be subject to disputes between the parties or may prove to be not as effective or as safe as we may have believed at the time of entering into such relationship. Also, we or others could identify safety, side effects or manufacturing problems with our products, including our devices, after they are on the market. Our results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments involving current and future products, sales growth of recently launched products, competition from other products including biosimilars, difficulties or delays in manufacturing our products and global economic conditions. In addition, sales of our products are affected by pricing pressure, political and public scrutiny and reimbursement policies imposed by third-party payers, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and healthcare cost containment. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. Our business may be impacted by government investigations, litigation and product liability claims. In addition, our business may be impacted by the adoption of new tax legislation or exposure to additional tax liabilities. If we fail to meet the compliance obligations in the corporate integrity agreement between us and the U.S. government, we could become subject to significant sanctions. Further, while we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors, or we may fail to prevail in present and future intellectual property litigation. We perform a substantial amount of our commercial manufacturing activities at a few key facilities, including in Puerto Rico, and also depend on third parties for a portion of our manufacturing activities, and limits on supply may constrain sales of certain of our current products and product candidate development. We rely on collaborations with third parties for the development of some of our product candidates and for the commercialization and sales of some of our commercial products. In addition, we compete with other companies with respect to many of our marketed products as well as for the discovery and development of new products. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers. Certain of our distributors, customers and payers have substantial purchasing leverage in their dealings with us. The discovery of significant problems with a product similar to one of our products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on our business and results of operations. Our efforts to acquire other companies or products and to integrate the operations of companies we have acquired may not be successful. A breakdown, cyberattack or information security breach could compromise the confidentiality, integrity and availability of our systems and our data.
