A Prospective Open-label, Multicenter Clinical Investigation to Assess the Safety and Performance of ARGOS-IO System in Patients Undergoing Implantation of a Boston Keratoprosthesis (BKPro)
In Brief
A clinical study evaluating ARGOS-IO system for Graft vs Host Disease and 4 related conditions. Completed, enrolled 13 participants across 2 sites.
Detailed Summary
The ARGOS-IO pressure sensor is intended to be implanted in the human eye in combination with Boston Keratoprosthesis (BKPro) surgery and to remain in place indefinitely. It is intended to be used together with the hand-held Mesograph reading device to telemetrically measure the intraocular pressure (IOP) of patients with a BKPro. The purpose of this study is to evaluate the safety and performance of the ARGOS-IO system in patients undergoing concomitant implantation of a BKPro and an ARGOS-IO sensor over the 12 month period beginning at implantation.

Timeline
Interventions
This study will enroll a minimum of 10 and a maximum of 15 patients. It is anticipated to be large enough to provide an initial estimate of common safety events and assessment of performance. Any adverse event (AE), serious adverse event (SAE), ADE (adverse device event) and SADE (serious adverse device event) will be listed. Incidence will be estimated with a 95% confidence interval (Pearson-Clopper, two-sided). The Bland-Altman method will be used to assess the limits of agreement between the IOP measurements ARGOS-IO and surgical manometry. When appropriate, two-sided 95% confidence intervals, for these limits will be calculated accounting for repeated measurements based on the method proposed by Zou (2011). Other secondary performance endpoints will be analyzed by descriptive and explorative statistical methods.
