Abstract:
The objective of this study was to explore the impact of the coronavirus disease 2019 epidemic on ongoing and upcoming drug clinical trials. Qualitative semi-structured interviews were conducted with clinical trial staff and clinical trial subjects were surveyed by questionnaire in this study. The results of interviews and questionnaire showed that coronavirus disease 2019 pandemic has led to many changes in the implementation of drug clinical trials, including: a variety of meetings being held online webinars using various platforms, telemedicine and follow-up by video, A large number of deviations from protocol and losses of follow-up, delivery of clinical trial drugs by express, additional workload caused by screening for coronavirus, and anxiety of subjects. These results suggest that the coronavirus disease 2019 outbreak has hindered the progress and damaged the quality of clinical trials. The online meeting, remote follow-up, express delivery of drugs and remote monitoring in the epidemic environment can ensure the progress of clinical trials to a certain extent, but they cannot fully guarantee the quality as before.
Insights
The coronavirus disease 2019 pandemic significantly disrupted drug clinical trials, causing protocol deviations and affecting participant follow-up. While remote methods aided trial progress, overall quality was compromised.
Area of Science:
- Clinical Research
- Epidemiology
- Pharmaceutical Sciences
Background:
- The coronavirus disease 2019 (COVID-19) pandemic presented unprecedented challenges to global healthcare systems.
- Ongoing and upcoming drug clinical trials faced significant operational hurdles due to public health measures and resource reallocation.
Purpose of the Study:
- To investigate the multifaceted impact of the COVID-19 pandemic on the execution of drug clinical trials.
- To identify specific changes and challenges encountered in clinical trial implementation during the pandemic.
Main Methods:
- Qualitative semi-structured interviews were conducted with clinical trial staff.
- Clinical trial participants were surveyed using questionnaires to gather their experiences.
Main Results:
- The pandemic necessitated a shift to online meetings and telemedicine for follow-ups.
- Increased protocol deviations, participant loss to follow-up, and express drug delivery were observed.
- Screening for COVID-19 added workload, and participants experienced heightened anxiety.
Conclusions:
- The COVID-19 outbreak hindered clinical trial progress and diminished trial quality.
- While remote strategies like online meetings and telemedicine partially mitigated delays, they could not fully preserve pre-pandemic quality standards.
