About ASCO The American Society of Clinical Oncology (ASCO) is the world's leading professional organization representing physicians who treat people with cancer. ASCO's members set the standard for patient care worldwide and lead the fight for more effective cancer treatments, increased funding for clinical and translational research, and, ultimately, cures for the many different cancers that strike millions of people around the world every year. About Allos Therapeutics, Inc. Allos Therapeutics, Inc. is a biopharmaceutical company focused on developing and commercializing innovative drugs for improving cancer treatments. The company's lead clinical candidate, RSR13 (efaproxiral), is a synthetic small molecule that has the potential to sensitize hypoxic (oxygen deprived) tumor tissues and enhance the efficacy of standard radiation therapy. Allos recently launched a multi-center Phase 3 randomized open label trial of RSR13 (efaproxiral) as an adjunct to whole brain radiation therapy for the treatment of brain metastases from breast cancer. The trial, called ENRICH (ENhancing Whole Brain Radiation Therapy In Patients with Breast Cancer and Hypoxic Brain Metastases), will seek to enroll approximately 360 patients at up to 50 cancer centers across North America. In addition, Allos is developing PDX, an injectable small molecule chemotherapeutic agent that has an enhanced potency and toxicity profile relative to methotrexate and other dihydrofolate reductase, or DHFR, inhibitors.
