Clinical Trial Summary

The objective of this study is to evaluate the feasibility of using the Hyivy device as a non-hormonal therapy in post-radiation patients with pelvic malignancies

Description:

Prior to study enrollment, all prospective participants will have the ability to contact the study team to learn more about the study and be provided with the relevant study-specific information. After being informed about the study and potential risks, all participants giving written informed consent will be assessed for their eligibility for the study, and enrolled participants will undergo a maximum 30-day screening period. On Day 0, eligible participants will start a 12-week use of Hyivy device with one visit on Week 6-7 and another on Week 12. After completing the 12-week intervention period, a virtual follow-up will be conducted on Week 16.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The usability and satisfaction of the Hyivy device by study-specific questionnaire	The usability and satisfaction of the Hyivy device for Hyivy's product development as assessed by study-specific questionnaires ranging from 11 (worst usability and satisfaction) to 55 (best usability and satisfaction)	12 weeks
Secondary	Changes in quality of life	Changes in quality of life as assessed by the European Organization for Research and Treatment of Cancer (EORTC)-QLQ-C30. All of the scales and single-item measures range in score from 0 to 100. Higher score for the functioning scales and global health status indicate a better state of the patient, while higher scores on the symptom and single-item scales indicate a worse state of the patient.	12 weeks
Secondary	Changes in sexual function as assessed by the EORTC-SHQ-22	Changes in sexual function as assessed by the EORTC-SHQ-22. The EORTC-SHQ-22 score range is from 0 to 100; a higher score represents a higher ("better") level of functioning, or a higher ("worse") level of symptoms.	12 weeks
Secondary	Changes in pelvic pain as assessed by visual analog scale (VAS).	Changes in pelvic pain as assessed by visual analog scale (VAS) ranging from 0 (no discomfort) to 10 (severe discomfort)	12 weeks
Secondary	Safety and tolerability of the Hyivy device as a non-hormonal therapy in post- radiation patients with pelvic malignancies as assessed by review of adverse events (AE) and serious adverse events (SAE).	Safety of the Hyivy device assessed by the Number of participants with treatment-related adverse events as assessed by CTCAE v4.0)	12 weeks
Secondary	The adherence of the Hyivy device assessed by participants' compliance	Adherence to the study regimen as assessed by comparing usage data collected by the Hyivy device to the recommended intervention regimen(adherence rate = # of times of patients did dilation therapy/# of times of patients should do dilation therapy *100%)	12 weeks
