Abstract:
There is a proliferation of clinical trials worldwide to find effective therapies for patients diagnosed with coronavirus disease 2019 (COVID-19). The endpoints that are currently used to evaluate the efficacy of therapeutic agents against COVID-19 are focused on clinical status at a particular day or on time to a specific change of clinical status. To provide a full picture of the clinical course of a patient and make complete use of available data, we consider the trajectory of clinical status over the entire follow-up period. We also show how to combine the evidence of treatment effects on the occurrences of various clinical events. We compare the proposed and existing endpoints through extensive simulation studies. Finally, we provide guidelines on establishing the benefits of treatments.
Insights
This study introduces new methods for analyzing patient recovery trajectories in coronavirus disease 2019 (COVID-19) clinical trials. These advanced endpoints offer a more complete assessment of therapeutic benefits beyond single time points.
Area of Science:
- Clinical Trials Methodology
- Infectious Disease Epidemiology
- Biostatistics
Background:
- Numerous clinical trials are investigating treatments for coronavirus disease 2019 (COVID-19).
- Current COVID-19 trial endpoints often focus on clinical status at specific time points or time to a single clinical event.
Purpose of the Study:
- To propose novel endpoints for evaluating COVID-19 therapies that utilize the full clinical trajectory.
- To demonstrate methods for combining evidence on treatment effects across multiple clinical events.
Main Methods:
- Analysis of clinical status trajectories over the entire follow-up period.
- Development of statistical methods to synthesize evidence from various clinical events.
- Extensive simulation studies to compare proposed and existing endpoints.
Main Results:
- The proposed trajectory-based endpoints provide a more comprehensive evaluation of treatment efficacy.
- Methods for combining evidence across multiple events enhance the power to detect treatment benefits.
- Simulation results indicate advantages of the new endpoints over traditional ones.
Conclusions:
- Trajectory-based endpoints offer a fuller picture of patient clinical course in COVID-19 trials.
- Combining evidence from multiple events strengthens the assessment of therapeutic benefits.
- Guidelines are provided for establishing treatment benefits using these advanced endpoints.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
