title: [Current status and issues in clinical trials of anticancer agents].
abstract: NDA filing and government approval for drug manufacturing marketing rights are processes based on collaboration among the concerned parties; a drug manufacturer (or importer), a medical institution and a government agency. However, quality guidelines are necessary for a scientific, ethical and economically efficient clinical study to be conducted. It is more than 3 years since the Ministry of Health and Welfare of Japan introduced "The Guidelines on Clinical Evaluation for Anti-tumor Drugs" in February, 1991. However, some practical problems have been pointed out by clinicians for revision. Among them we discuss the following items for revision of the Guidelines and made suggestions and opinions from the manufacturers' point of view: Phase I: Number of institutions for clinical study, determination of MTD and study design. Phase II: Introduction of foreign data, late phase II study for plural numbers of indications at time of NDA filing and evidence of usefulness in concurrent therapy.
