In an article published in JCO Oncology Practice, David Waterhouse, MD, MPH, of Oncology Hematology Care, Cincinnati, Ohio, and colleagues presented the results of a recent ASCO survey of clinical programs on the early impact of the COVID-19 pandemic on the performance of oncology clinical trials.1 The findings highlight the numerous issues faced by the programs, steps that are being taken to address these issues, and the potential for beneficial changes in the conduct of trials post–COVID-19.

The survey, conducted in late March 2020, was offered to clinical programs represented on the ASCO Cancer Research Committee and Research Community Forum Steering Group and taskforces to obtain information on the types of changes and challenges clinical trial programs were experiencing early in the COVID-19 pandemic. Among 32 survey respondents, 14 represented academic programs and 18, community-based programs. Survey findings are summarized here. A detailed report of the survey findings can be found on ASCO’s website:

Survey Findings

• Research Program Policies and Priorities: Most respondents (64%) reported that their institutions had developed and instituted formal policies related to the COVID-19 pandemic, with most reporting having implemented remote patient care interactions, including patient review of symptoms (90.6%) and telehealth visits (87.5%). Approximately three-quarters of programs mandated remote work by research staff; 65.6% had implemented remote site initiation visits, and 71.9% had remote monitoring by sponsors and/or contract research organizations.

Delay of clinical research activities was common: 59.4% of programs halted screening and/or enrollment for certain clinical trials, and 59.4% had stopped research-only visits except those providing cancer treatment. Half of the programs had stopped research-only blood and/or tissue collections.

Approximately half (53.1%) of programs reported prioritizing enrollment for certain clinical trials, with reported prioritization strategies including a tier-based approach based on patient needs, safety, and disease severity; potential patient and site burdens; and availability and allocation of program resources. National Cancer Institute (NCI)-funded cancer care delivery research and prevention/control trials were halted in accordance with NCI guidance.

• Challenges in Conducting Clinical Trials: More than half of programs reported a decrease in patient ability or willingness to come to the site (54.8%) and reported the staff time required to organize, implement, and conduct telehealth visits was a significant challenge. In addition, 51.6% reported limited availability of ancillary services such as radiology, surgery, and cardiology. Time spent in discussion with sponsors, contract research organizations, and institutional review boards with regard to modification of clinical trial procedures was cited as a challenge by 51.6%.

Opportunities to Improve Clinical Trials: Respondents also identified a number of ways in which experience during the COVID-19 pandemic might help to improve clinical trial conduct post–COVID-19. Among the potential improvements cited were telehealth visits for trial participants (90.3%), remote patient review of symptoms (77.4%), remote site initiation visits (71.0%), monitoring by sponsors/contract research organizations (64.5%), and remote safety lab collections (45.2%).


  • The survey identified numerous challenges posed to clinical trial conduct during the COVID-19 pandemic.
  • Measures implemented to face these challenges offer the opportunity for improvements in clinical trial conduct post–COVID-19.

Other opportunities to improve clinical trial conduct identified by respondents included improved efficiency during study launch and enrollment (eg, enhanced electronic institutional review board communications and responses); remote patient care (including shipping oral drugs directly to patients and remote adverse-event assessments); flexibility with drug and specimen distribution, management, and documentation for transportation; and streamlined data collection.

Increased remote work by research staff was identified as a potential means for improving job productivity, satisfaction, and staff retention and alleviating space issues at study sites.

Strategies for Conducting Trials During the COVID-19 Pandemic

The authors stated: “Adaptations to clinical trial practices during the pandemic are critical to ensuring patient access to both ongoing and new study treatments. Clinical trial programs should follow guidance on conducting clinical trials during the pandemic from the U.S. Food and Drug Administration, NCI, ASCO, and others.” They recommended programs should also consider adopting a number of “high-level” strategies to assist in meeting the challenges posed by the pandemic:

  • Keep participants informed about changes to trials and their care and remind participants to alert their research team about changes to their health
  • Develop formal COVID-19 standard operating procedures for clinical trials that could be repurposed with other disease outbreaks
  • Leverage e-signatures for informed consent and other study documents
  • Organize daily staff “huddles” to provide updates and discuss operational challenges
  • Promote telehealth visits for patients
  • Implement patient review of symptoms and adverse events (eg, through patient portal, e-mail, phone, video)
  • Establish a system for prioritizing clinical trial resource allocation (eg, determine which trials should maintain screening and enrollment)
  • Require remote study initiation visits and monitoring from trial sponsors and contract research organizations
  • Use remote safety lab collections, where feasible
  • Ship oral drugs directly to patients
  • Communicate any changes or concerns about existing trials to institutional review boards
  • Ensure, thorough documentation of changes to procedures and modifications to or deviations from protocols, and use a “COVID-19” tag to facilitate searching after the pandemic.

They noted such changes offer the potential to make clinical trials more patient-friendly and reduce the time and expense of participating in clinical trials.

The authors summarized, in part: “The changes in clinical trial procedures identified by the survey could serve as strategies for other programs attempting to maintain their clinical trial portfolios during the COVID-19 pandemic. Additionally, many of the adaptations to trials made during the pandemic provide a long-term opportunity to improve and transform the clinical trial system.”
