Journal ArticleDOI

Relationships between drug activity in NCI preclinical in vitro and in vivo models and early clinical trials.

TL;DR: For 39 agents with both xenograft data and Phase II clinical trials results available, in vivo activity in a particular histology in a tumour model did not closely correlate with activity in the same human cancer histology, casting doubt on the correspondence of the pre-clinical models to clinical results.
Journal ArticleDOI

Accelerated Titration Designs for Phase I Clinical Trials in Oncology

TL;DR: Accelerated titration (i.e., rapid intrapatient drug dose escalation) designs appear to effectively reduce the number of patients who are under-treated, speed the completion of phase I trials, and provide a substantial increase in the information obtained.
Journal ArticleDOI

Phase I trial of continuous infusion flavopiridol, a novel cyclin-dependent kinase inhibitor, in patients with refractory neoplasms.

TL;DR: The maximum-tolerated dose (MTD) of infusional flavopiridol is 50 mg/m2/d x 3 with dose-limiting secretory diarrhea, based on chronic tolerability, which is the recommended phase II dose without ADP.
Journal ArticleDOI

Clinical Trial Designs for Cytostatic Agents: Are New Approaches Needed?

TL;DR: Options for modifying trial designs to accommodate cytostatic agents are discussed and examples are given where these options have been tried or are currently being tried.
Journal ArticleDOI

Phase I Trial of 72-Hour Continuous Infusion UCN-01 in Patients With Refractory Neoplasms

TL;DR: Preliminary evidence suggests UCN-01 modulation of both PKC substrate phosphorylation and the DNA damage-related G(2) checkpoint may be responsible for disease stability in refractory neoplasms.
