[Early clinical trials in ECTG. Early Clinical Trial Group]. 1996

M Ogawa
Aichi Cancer Center, Japan.

Methodology to conduct phase I trials in the Early Clinical Trial Group (ECTG) in Europe was reviewed and compared with current status of the trials in Japan. Single dose acute toxicity studies and repeated dose toxicity studies were required in order to enter phase I trials in Europe, while in Japan those results and various other toxicity studies such as mutagenecity, carcinogenecity and reproductive toxicity were required. Since significant numbers of new anticancer drugs are dropped in the early stage of clinical investigations, it is recommended that unnecessary toxicological studies be avoided. Repeated administration and dose escalations in the same patients are allowed during phase I trials in ECTG, partly in consideration of the patient's desire to obtain antitumor effects. Dose intensity and quality of life are considered in order to decide the optimal dose and schedule in phase II trials.

D017321 Clinical Trials, Phase I as Topic Works about studies performed to evaluate the safety of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques in healthy subjects and to determine the safe dosage range (if appropriate). These tests also are used to determine pharmacologic and pharmacokinetic properties (toxicity, metabolism, absorption, elimination, and preferred route of administration). They involve a small number of persons and usually last about 1 year. This concept includes phase I studies conducted both in the U.S. and in other countries.
