Spectrum Pharmaceuticals Announces a National Institute-Sponsored Phase 1/2 Study of in Thymic Malignancies

IRVINE, Calif., Mar 22, 2010 (BUSINESS WIRE) -- Spectrum Pharmaceuticals, Inc. (NasdaqGM:SPPI), a commercial-stage company with a primary focus in oncology and hematology, and TopoTarget A/S, today announced that the first patient has been dosed in a National Cancer Institute (NCI)-sponsored Phase 1/2 trial of belinostat in combination with cisplatin, doxorubicin and cyclophosphamide in the first line treatment of advanced or recurrent thymic malignancies. The trial is designed to determine what drug doses can be safely administered together in patients, and to make dose recommendations for future clinical trials. This trial is among the first to test the feasibility of simultaneously administering a (HDAC) inhibitor, such as belinostat, with common agents such as cisplatin, doxorubicin, and cyclophosphamide, in the first line treatment of advanced or recurrent thymic malignancies. The study is expected to recruit between 30 and 48 evaluable patients.

"We are pleased that the NCI continues to investigate the use of belinostat in the treatment of various ," said Rajesh C. Shrotriya, MD, Chairman, Chief Executive Officer, and President of Spectrum Pharmaceuticals. "We believe belinostat has the potential to be an effective treatment in combination with existing chemotherapeutic agents for the treatment of thymomas, thymic malignancies, and other cancers."

About Belinostat

Belinostat (PXD 101) is a novel HDAC inhibitor that is being studied in multiple clinical trials as a single agent or in combination with chemotherapeutic agents for the treatment of various hematological and solid cancers. Its anticancer effect is thought to be mediated through multiple mechanisms of action, including the inhibition of cell proliferation, induction of (programmed cell death), inhibition of angiogenesis, induction of differentiation, and the resensitization of cells that have overcome drug resistance to anticancer agents such as platinums, taxanes and topoisomerase II inhibitors. Belinostat is the only HDAC inhibitor in clinical development with multiple potential routes of administration, including intravenous administration, continuous intravenous infusion and oral administration.

About Thymoma and Thymic Carcinoma

Thymus cancers are uncommon cancers that start in the thymus. This small organ is located just behind the breast bone in the front part of the mediastinum, the space in the chest between the lungs. The thymus is an important part of the body's immune system. During fetal development and childhood, the thymus is involved in the production and maturation of T lymphocytes (also known as T cells), a type of white blood cell. T lymphocytes develop in the thymus and then travel to lymph nodes (bean- sized collections of immune system cells) throughout the body. There they help the immune system protect the body from viruses, fungus, and other types of infections. The thymus contains different types of cells, each of which can develop into different types of cancer: Epithelial cells give the thymus its structure and shape. They can give rise to thymomas and thymic carcinomas; Lymphocytes make up most of the rest of the thymus. Whether in the thymus or in other parts of the body, these immunes system cells can develop into cancers called Hodgkin disease and non-Hodgkin ; and Kulchitsky cells, or neuroendocrine cells, are much less common cells that normally release certain hormones. These cells can give rise to cancers called carcinoid tumors. Thymomas and thymic carcinomas are tumors that start from thymic epithelial cells.

About the Belinostat Registrational Study

Belinostat is currently in registrational trial, under a Special Protocol Assessment (SPA), as a monotherapy for Peripheral T-Cell (PTCL), an indication which has been granted Orphan Drug and Fast Track designation by the U.S. Food and Drug Administration (FDA). The registrational trial is in an open-label, multicenter, single arm efficacy and safety study in patients with relapsed or refractory peripheral T-cell lymphoma, who have failed at least one prior systemic therapy. The primary endpoint is objective response rate (ORR).

About the NCI

The National Cancer Institute (NCI) is part of the National Institutes of Health (NIH), which is one of 11 agencies that compose the Department of Health and Human Services (HHS). The NCI, established under the National Cancer Institute Act of 1937, is the Federal Government's principal agency for cancer research and training. The National Cancer Act of 1971 broadened the scope and responsibilities of the NCI and created the National Cancer Program. Over the years, legislative amendments have maintained the NCI authorities and responsibilities and added new information dissemination mandates as well as a requirement to assess the incorporation of state-of-the-art cancer treatments into clinical practice.

The National Cancer Institute coordinates the National Cancer Program, which conducts and supports research, training, health information dissemination, and other programs with respect to the cause, diagnosis, prevention, and treatment of cancer, rehabilitation from cancer, and the continuing care of cancer patients and the families of cancer patients.
