Efficiency perspectives on adaptive designs in stroke clinical trialsKen Cheung
Department of Biostatistics, Columbia University, 722 W 168th Street, New York, NY 10032, USA
Stroke 42:2990-4. 2011..This understanding is critical to appreciate the limitations, as well as the full promise, of adaptive designs, so that investigators can deploy an appropriate statistical design--be it adaptive or not--in a clinical study...
Selecting promising treatments in randomized Phase II cancer trials with an active controlYing Kuen Cheung
Department of Biostatistics, Mailman School of Public Health, Columbia University, New York, NY 10032, USA
J Biopharm Stat 19:494-508. 2009..The operating characteristics of the proposed methods are compared to that of a single-stage design via simulations: The sample size requirement is reduced substantially and is feasible at an early stage of drug development...
Simple sequential boundaries for treatment selection in multi-armed randomized clinical trials with a controlYing Kuen Cheung
Department of Biostatistics, Mailman School of Public Health, Columbia University, 722 West 168th Street, New York, New York 10032, USA
Biometrics 64:940-9. 2008....
Selecting promising ALS therapies in clinical trialsYing Kuen Cheung
Department of Biostatistics, Columbia University Mailman School of Public Health, New York, NY 10032, USA
Neurology 67:1748-51. 2006....
Continuous Bayesian adaptive randomization based on event times with covariatesYing Kuen Cheung
Department of Biostatistics, Mailman School of Public Health, Columbia University, 722 West 168th Street, New York, NY 10032, USA
Stat Med 25:55-70. 2006..We illustrate these methods by application to a phase II selection trial in acute leukaemia. A simulation study in the context of this trial is presented...
Calibration of prior variance in the Bayesian continual reassessment methodShing M Lee
Department of Biostatistics, Mailman School of Public Health, Columbia University, 722 West 168th Street, New York, NY 10032, USA
Stat Med 30:2081-9. 2011..However, the new approaches yield a smaller interval of toxicity probabilities in which a neighboring dose may be selected...
Continual reassessment method with multiple toxicity constraintsShing M Lee
Department of Biostatistics, Columbia University, New York, NY 10032, USA
Biostatistics 12:386-98. 2011..Based on simulations, our proposed methods achieve comparable accuracy in identifying the maximum tolerated dose but have better control of the erroneous allocation and recommendation of an overdose...
Exact two-sample inference with missing dataYing Kuen Cheung
Department of Biostatistics, Mailman School of Public Health, Columbia University, New York, New York 10032, USA
Biometrics 61:524-31. 2005..Monte Carlo approximation by the Gibbs sampler is proposed, and is shown to be fast and accurate via simulation. The method is illustrated in two small data sets for which asymptotic inferential procedures may not be appropriate...
A simple technique to evaluate model sensitivity in the continual reassessment methodYing Kuen Cheung
Department of Biostatistics, Mailman School of Public Health, Columbia University, New York, New York 10032, USA
Biometrics 58:671-4. 2002..The technique presented is found to be a useful supplement to simulation when planning a phase I trial...
A novel, efficient, randomized selection trial comparing combinations of drug therapy for ALSPaul H Gordon
Department of Neurology, Columbia University, New York, USA
Amyotroph Lateral Scler 9:212-22. 2008..This phase II design was efficient, leading to treatment selection after just 60 patients, and can be used in other phase II trials to assess different agents...
Monitoring the rates of composite events with censored data in phase II clinical trialsYing Kuen Cheung
Department of Biostatistics, Mailman School of Public Health, Columbia University, New York, New York 10032, USA
Biometrics 58:89-97. 2002..Application to a leukemia trial with a composite event shows that the method can reduce trial duration substantially while maintaining the reliability of interim decisions...
On the use of nonparametric curves in phase I trials with low toxicity toleranceYing Kuen Cheung
Division of Biostatistics, School of Public Health, Columbia University, New York, New York 10032, USA
Biometrics 58:237-40. 2002..Interestingly, improvement can be achieved by prescribing slightly more informative priors. Some guidelines for prior elicitation are established using a connection between this curve-free method and the continual reassessment method...
