Clinical Update on Pemetrexed

The articles in this supplement to ONCOLOGY, "Clinical Update on Pemetrexed," are presented by leading international clinical and preclinical investigators in the arenas of thoracic, gastrointestinal, breast, and gynecologic cancers. They cover a wide range of topics that focus on the promising agent pemetrexed (Alimta). Pemetrexed is a novel folate antimetabolite that inhibits thymidylate synthase, dihydrofolate reductase, and glycinamide ribonucleotide formyl transferase, all of which are involved in pyrimidine and purine synthesis, resulting in impeded synthesis of the nucleotide precursors of DNA and RNA. This agent has demonstrated activity in clinical trials in a variety of tumor types, such as those presented herein. In February 2004, the US Food and Drug Administration (FDA) approved pemetrexed-in combination with cisplatin, a commonly used chemotherapy agent- for use in the treatment of malignant pleural mesothelioma, a devastating cancer often associated with asbestos exposure. In July 2004, The Oncologic Drugs Advisory Committee (ODAC) of the FDA positively endorsed pemetrexed for accelerated approval as monotherapy in the second-line treatment of non-small-cell lung cancer. The topics in this volume include the biochemical pharmacology of pemetrexed, preclinical/phase I studies, and phase II and III studies in thoracic (non- small-cell lung cancer and mesothelioma), gastrointestinal (pancreas, bladder, colorectal, and gastric), breast, and gynecologic cancers. Moreover, data from current and future pharmacogenomics and translational research with pemetrexed and gemcitabine (Gemzar) are presented. In addition to presenting current trial data in this volume, the authors present information on clinical trends and the design of future trials focusing on pemetrexed, either as a single agent or in combination. Finally, an additional goal was to produce enduring material for investigators to aid them in current and future study. Therefore, the material contained in this volume is intended to be a thorough, objective, balanced presentation of clinical and preclinical research with pemetrexed in multiple tumor types. I hope that you, the reader, find the data and information to be stimulating, timely, and useful in patient management and/or the design of clinical trials.
