Genzyme Launches New Diagnostic Test for Common Blood Cancerp53 Mutation Analysis Offers Critical Prognostic and Predictive Information for B-Cell Chronic Lymphocytic Leukemia
CAMBRIDGE, Mass., July 27 (HSMN NewsFeed) -- Genzyme Corporation (Nasdaq: GENZ ) announced today the availability of its p53 Mutation Analysis for B-cell chronic lymphocytic leukemia (B-CLL). P53 is a tumor suppressor gene that stops cell division when DNA damage is present. When the p53 gene does not function normally, genetic mutations that can occur in dividing cells remain unchecked, thereby leading to the accumulation of abnormal, malignant cells. Mutations in p53 are present in greater than 50 percent of all human cancers, including colon, breast, lung, bladder, brain, liver, and hematological malignancies.
A significant number of patients with B-CLL have a dysfunctional p53 gene caused by mutations and deletions, and this number increases as the disease progresses. Studies show that p53 is a poor prognostic factor in B-CLL.
Currently, physicians generally test for p53 deletions using a technology known as "fluorescent in-situ hybridization" (FISH). FISH detects a deletion of a fragment of chromosome 17 that bears the p53 gene. However, B-CLL patients may have a p53 deletion, mutation, or both. Genzyme's new test is a gene sequencing assay that detects specific mutations in the p53 gene with a higher degree of sensitivity than FISH alone, thereby providing more comprehensive diagnostic information for high-risk patients. With the new availability of the p53 Mutation Analysis, Genzyme is expanding its diagnostic menu for B-CLL patients. The company also offers a minimal residual disease test, which detects very low levels of disease in B-CLL patients.
Genzyme believes that effective cancer treatment requires personalized medicine, directing specific therapies at the patients most likely to benefit from them. This important convergence of diagnostics and therapeutics is a priority for Genzyme.
In 2005, Genzyme launched three new cancer tests directly related to understanding a patient's response to targeted therapies. This year, Genzyme introduced an important new test to monitor drug resistance in chronic myeloid leukemia patients who are treated with Gleevec® (imatinib mesylate) and launched two new molecular tests for acute myelogenous leukemia (AML): FLT3 Mutation Analysis and WT1 RQ-PCR. FLT3 mutations are considered a prognostic indicator of poor survival and response to standard chemotherapies. The WT1 RQ PCR test allows physicians to monitor AML patients for early relapse during and following therapy. Together, these tests may enable oncologists to better manage their patients.
"The availability of these new tests are just the beginning of Genzyme's commitment to deliver life-saving targeted medicine," said Mara Aspinall, president of Genzyme Genetics, the business unit of Genzyme Corp. focused on the research, development and provision of complex testing services. "We will continue to develop innovative testing that helps physicians select appropriate therapies for their patients."
About Chronic Lymphocytic Leukemia
CLL is the most prevalent form of adult leukemia, affecting approximately 120,000 people in Europe and the United States. The disease is most commonly diagnosed among people age 50 or older. CLL is characterized by the accumulation of functionally immature white blood cells (lymphocytes) in the bone marrow, blood, lymph tissue, and other organs. Two types of lymphocytes are present in the blood, B cells and T cells. About 95 percent of CLL cases involve cancerous B cells. Because these B cells have a longer than normal life span, they begin to build up and "crowd out" the normal, healthy blood cells. The accumulation of functionally immature cells in the bone marrow excludes the generation of healthy cells and can become fatal. Symptoms include fatigue, bone pain, night sweats, fevers, and decreased appetite and weight loss. Bone marrow involvement also leads to weakening of the immune system, exposing the patient to a higher risk of infection.
Campath® (alemtuzumab) is indicated in the United States for the treatment of patients with B-CLL who have been treated with alkylating agents and have failed fludarabine therapy. Genzyme and Schering AG, Germany, are co-developing Campath in oncology and other indications. The product is marketed in the United States by Berlex Laboratories, a U.S. affiliate of Schering.
Campath is the first and only humanized monoclonal antibody approved for the treatment of B-CLL in patients who have failed both alkylating agents and fludarabine phosphate treatment. Campath works by targeting the "CD52" antigen, which is one of the most common antigens found on B and T cells. When Campath binds to this CD52 antigen, it activates the immune system to destroy targeted cells not only in the blood but also in the bone marrow. Campath is not currently indicated as a first-line treatment in CLL.
Campath should be administered under the supervision of a physician experienced in the use of antineoplastic therapy. Campath has a boxed warning which includes events of hematologic toxicity, infusion reactions, and infections/opportunistic infections.
Campath is contraindicated in patients who have active systemic infections, underlying immunodeficiency (e.g., seropositive for HIV), or known Type 1 hypersensitivity or anaphylactic reactions to Campath or to any one of its components.
The most commonly reported infusion-related adverse events were rigors, drug-related fever, nausea, vomiting, and hypotension. Hematologic toxicities included pancytopenia/marrow hypoplasia, anemia, thrombocytopenia, neutropenia, and profound lymphopenia, and should be monitored. Infections reported included sepsis, pneumonia, and opportunistic infections such as CMV, candidiasis, aspergillosis, and mucormycosis.
