Trials that died the same way

• Impact of T Cells on Age-related Vascular Dysfunction: A Translational Approach
  “COVID initially delayed plans to begin recruitment of subjects. Subsequently, the departure of a clinical investigator and loss of access to equipment and study subject population resulted in study termination before any subjects were enrolled.” (71% match in meaning)
• Low Cost QTc Meter for Long QT Syndrome Screening in Primary Care
  “COVID, lack of funding and interruption of patient recruitment led to ending the study early.” (71% match in meaning)
• Assessing Closed-loop Insulin Delivery in Children With Type 1 Diabetes.
  “The sponsor has requested to end the study prematurely due to the accumulation of delays caused by COVID-19 as potential participants were hesitant to allow staff members into their homes or stay at the hospital per the study design.” (69% match in meaning)
• Foot Perfusion Analysis to Predict Limb Salvage
  “COVID-19 disrupted recruitment and follow-up in 2020. Following the investigators' departure, recruitment could not resume, leading to premature study termination.” (69% match in meaning)
• Global CALM Implementation Study
  “Study recruitment \& data collection ceased in Dec 2022 in part due to funding shortages and the impact of the COVID-19 Pandemic. 40 clinician-participants consented; 35 completed measures; no data were analyzed or published; REB was closed Nov 2024.” (69% match in meaning)
