Webdose escalation: A progressive increase in the strength of any treatment (e.g., a drug or a radiation dose), to improve its tolerability or maximize its effect. WebNov 1, 2024 · Fictional examples of how the dose-escalation method chosen can alter the outcomes of a phase 1 study are described, including the number of patients enrolled, the trial’s timeframe, and the dose level chosen as MTD. Finally, the recent trends in dose-escalation methods applied in phase 1 trials in the immunotherapeutics era are reviewed.

Patients often have limited treatment options to consider when entering a dose-escalation oncology trial. In such studies which generally aim to assess a novel agent's safety profile based on a limited number of patients, one critical and challenging task is to identify the maximum tolerated dose (MTD) that may be the final …

A number of novel model-based and model-assisted designs have been proposed to find the MTD in phase I clinical trials, but their differences and relative pros and cons are not clear to many practitioners. We review three model-based designs, including the continual reassessment method (CRM), dose escalation with overdose …
WebNov 13, 2024 · All patients will receive NKTR-255 once every three weeks. Patients will be observed for a dose-limiting toxicity (DLT) window of three weeks following the first NKTR-255 dose. A two-parameter Bayesian logistic regression model (BLRM) will be used during the escalation part of the study for dose level selection and for determination of MTDs.
