Phase I trial design for solid tumor studies of targeted, non-cytotoxic agents: theory and practice.

BACKGROUND New targeted, non-cytotoxic anticancer agents, such as small-molecule kinase inhibitors, pose challenges to the current phase I paradigm of dose selection based on toxicity. Moreover, increasing the drug dose to toxicity may be unnecessary for drug effect, making the use of maximum tolerated dose as a surrogate of effective dose inappropriate in the phase I setting. Because little is...

Randomized phase III clinical trial designs for targeted agents.

PURPOSE Cancer therapies with mechanisms of action which are very different from the more conventional chemotherapies are now being developed. In this article, we investigate the performance of several phase III clinical trial designs, both for testing the overall efficacy of a targeted agent and for testing its efficacy in a subgroup of patients with a tumor marker present. We study different ...

Clinical trial designs for targeted agents.

With an increasing number of targeted agents available for testing, clinical trials must be rationally designed based on sound knowledge of the molecular mechanisms linking target and disease, fortified by strong preclinical data demonstrating how this relationship is modified by the targeted agent. Patients and resources are precious and should be expended judiciously on clinical trials that a...

Challenges and Innovations in Phase I Dose-Finding Designs for Molecularly Targeted Agents and Cancer Immunotherapies

Phase I oncology trials are designed to identify a safe dose with an acceptable toxicity profile. In traditional phase I dose-finding design, the dose is typically determined based on the probability of severe toxicity observed during the first treatment cycle. The recent development of molecularly targeted agents and cancer immunotherapies call for new innovations in phase I designs, because o...

Efficiency of New Dose Escalation Designs in Dose-Finding Phase I Trials of Molecularly Targeted Agents

BACKGROUND Statistical simulations have consistently demonstrated that new dose-escalation designs such as accelerated titration design (ATD) and continual reassessment method (CRM)-type designs outperform the standard "3+3" design in phase I cancer clinical trials. METHODS We evaluated the actual efficiency of different dose escalation methods employed in first-in-human phase I clinical tria...
