Post # of 340 
RICHMOND, Calif. and WALTHAM, Mass., Oct. 2, 2017 /PRNewswire/ -- Sangamo Therapeutics, Inc. (NASDAQ: SGMO), the leader in therapeutic genome editing, and Bioverativ Inc. (NASDAQ: BIVV), a global biopharmaceutical company focused on the discovery, development, and commercialization of innovative therapies for hemophilia and other rare blood disorders, announced today that the U.S. Food and Drug Administration (FDA) has accepted the Investigational New Drug (IND) application for ST-400, a gene-edited cell therapy candidate for people with transfusion-dependent beta-thalassemia. Sangamo and Bioverativ are developing ST-400 as part of an exclusive worldwide collaboration to develop and commercialize gene-edited cell therapies for beta-thalassemia and sickle cell disease.

"We are very pleased with the FDA's acceptance of the IND for ST-400 for the treatment of beta-thalassemia and look forward to initiating the first clinical trial," said Edward Conner, M.D., chief medical officer at Sangamo. "We believe the precision, efficiency and specificity of zinc finger nuclease gene editing technology will differentiate ST-400 among other genomic therapies in development for beta-thalassemia."

"Beta-thalassemia is a serious, lifelong blood disorder, and many children and adults with the disease require frequent and demanding blood transfusions that may lead to iron overload and long-term organ damage," said Tim Harris, Ph.D., D.Sc., executive vice president of research and development at Bioverativ. "The advancement of ST-400 demonstrates our commitment to progressing novel science that has the potential to make a meaningful, lasting difference in the lives of people with beta-thalassemia."

The IND enables Sangamo to initiate a Phase 1/2 clinical trial to assess the safety, tolerability and efficacy of ST-400 in adults with transfusion-dependent beta-thalassemia. Sangamo expects to open several clinical sites across the United States and begin enrolling patients in the first half of 2018.

Beta-thalassemia is an inherited blood disorder caused by mutations in the beta-globin gene that leads to reduced or absent production of adult hemoglobin, the protein in red blood cells that carries oxygen to cells throughout the body. The disorder causes the destruction of red blood cells, which results in severe anemia and reduced oxygen transport to various tissues in the body.

According to the World Health Organization, there are approximately 100,000 treated beta-thalassemia patients worldwide, with ~19,000 of those in the United States and Europe.1 The majority of these patients are transfusion-dependent, and their current standard of care includes a chronic regimen of red blood cell transfusions, which may lead to iron overload and organ damage even with daily iron chelation therapy. Allogeneic bone marrow transplant may be a treatment option for these patients if a suitable donor can be found, but carries substantial risks such as graft-versus-host disease and chronic morbidity.

About ST-400 and the Phase 1/2 Clinical Trial
ST-400 is an autologous cell therapy that involves gene editing of a patient's own hematopoietic stem cells (HSCs) using zinc finger nuclease (ZFN) technology. It is being developed with the aim of providing a one-time treatment for people with transfusion-dependent beta-thalassemia by increasing production of fetal hemoglobin, which can more effectively carry oxygen, potentially eliminating the need for chronic blood transfusions. As part of the Phase 1/2 clinical trial protocol, a patient's HSCs are isolated from the blood, and the cells then undergo ex-vivo gene editing using ZFNs to modify a specific sequence of the BCL11A gene that suppresses fetal hemoglobin production in erythrocytes. Following a conditioning regimen, patients will be infused with their own modified HSCs, with the goal of producing increased amounts of fetal hemoglobin to compensate for the decrease in functional beta-globin levels, potentially resolving the need for chronic blood transfusions and ameliorating the complications from major organ failure that frequently arise from the disease.

About the Sangamo and Bioverativ collaboration
Sangamo and Bioverativ have an exclusive worldwide collaboration to develop and commercialize ZFN-mediated gene-edited cell therapies for the treatment of beta-thalassemia and sickle cell disease. Based on the terms of the agreement, Sangamo is responsible for conducting the ST-400 Phase 1/2 clinical trial, and Bioverativ will be responsible for subsequent worldwide clinical development, manufacturing, and commercialization.

Sangamo's Forward-Looking Statements
This press release contains forward-looking statements, including, but not limited to, statements related to the therapeutic potential of gene editing and ST-400, including the potential of ST-400 as a one-time treatment option for people with beta-thalassemia, the planned Phase 1/2 clinical trial of ST-400, including its design and Sangamo's expectations for opening clinical sites and enrolling patients and the timing thereof, as well as other statements that are not historical facts. These forward-looking statements are based on Sangamo's current plans, objectives, estimates, expectations and intentions and inherently involve significant risks and uncertainties. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties, which include, without limitation, risks and uncertainties associated with: gene therapy product candidate development and the inherent uncertainty of clinical success, including the risks that Sangamo and/or Bioverativ may encounter unanticipated toxicity or adverse events in, or fail to demonstrate the efficacy of ST-400 in, clinical development and that the planned Phase 1/2 clinical trial may otherwise fail to validate and support the tolerability and efficacy of ST-400; Sangamo's substantial dependence on the clinical success of its lead therapeutic programs; the initiation, enrollment and completion of the stages of its clinical trials, including Sangamo's potential inability to enroll the planned Phase 1/2 clinical trial of ST-400 in a timely manner or at all; technological challenges; the lengthy and uncertain regulatory approval process; Sangamo's and Bioverativ's ability to develop a commercially viable ST-400 product or other products under the collaboration; technological developments by competitors and others in the genomic therapy field; and Sangamo's dependence on its collaboration with Bioverativ for the development of ST-400 and its ability to maintain its collaboration with Bioverativ.
