Trial Outcomes & Findings for Patient Acceptance and Preference Among Screening Modalities for Detection of Barrett's Esophagus (NCT NCT04301986)

NCT ID: NCT04301986

Last Updated: 2023-05-08

Results Overview

Impact of Events Score (IES): scale was developed to assess the distress associated with a specific life event. IES scores range from 0-75, with higher scores indicating more severe distress associated from an event. Scores ≥ 44 indicate a event has severe impact on self-reported distress while scores ≤ 25 indicate the event may have an effect on distress.

TNE Followed by EGD
Participants will undergo administration of a transnasal endoscopy (TNE) prior to their scheduled clinically indicated upper endoscopy performed per routine standard of care. Following the procedure, a follow-up phone call will be made during which an impact of events scale related to the subjective distress of each procedure, a preference and acceptance questionnaire, and adverse events related to study participation will be collected. Transnasal Endoscopy (TNE): In an upright position, the scope will be inserted via the nares to examine the posterior pharynx, esophagus and proximal stomach with the transnasal endoscopy approach. The scope will be withdrawn from the nares following completion of the exam. Esophagogastroduodenoscopy: Laying on the participants' left side, the flexible endoscope is inserted through the mouth to allow visualization of the esophageal mucosa from the upper esophageal sphincter all the way to the esophagogastric junction (EGJ).
Cytosponge, Then TNE, Followed by EGD
Participants will undergo administration of Cytosponge and transnasal endoscopy (TNE) prior to their scheduled clinically indicated upper endoscopy performed per routine standard of care. Following the procedure, a follow-up phone call will be made during which an impact of events scale related to the subjective distress of each procedure, a preference and acceptance questionnaire, and adverse events related to study participation will be collected. Cytosponge: In a seated position, participants will swallow the Cytosponge capsule with 150-250 mL of water. Seven minutes and 30 seconds to ten minutes after ingestion, the sponge is then withdrawn by gentle traction on the suture. After retrieval, the string is cut and the retrieved foam sphere containing the cytological specimen is immersed in fixative and stored refrigerated (1° to 12°C \[34° to 54°F\]). Transnasal Endoscopy (TNE): In an upright position, the scope will be inserted via the nares to examine the posterior pharynx, esophagus and proximal stomach with the transnasal endoscopy approach. The scope will be withdrawn from the nares following completion of the exam. Esophagogastroduodenoscopy: Laying on the participants' left side, the flexible endoscope is inserted through the mouth to allow visualization of the esophageal mucosa from the upper esophageal sphincter all the way to the esophagogastric junction (EGJ).

PRIMARY outcome

Timeframe: 7 days post-EGD

Population: All participants enrolled into the arm completing all 3 maneuvers (i.e., Cytosponge, Then TNE, Followed by EGD).

IES scores range from 0-75, with higher scores indicating more severe distress associated from an event. Scores ≥ 44 indicate a event has severe impact on self-reported distress while scores ≤ 25 indicate the event may have an effect on distress.

SECONDARY outcome

Timeframe: 7 days post-EGD

Population: Preferred screening was inadvertently omitted during form creation and these data were not collected.

Participants asked to rank preferred screening modality in order (1,2,3). Scores range from 0-3. Scores of 1 indicate a preference, while scores of 3 indicate aversion.
