Details and patient eligibility

About

The goal of this non-inferiority clinical trial is to evaluate the efficacy of Tappt, a novel digital medication companion solution, among individuals with hepatitis C virus (HCV) who are starting a daily oral medication regimen following standard of care in a clinical pharmacy setting.

• The primary aim is to assess the non-inferiority of Tappt with medication adherence, treatment completion, sustained virologic response (SVR) assessment, and SVR achievement rates.
• The secondary aim is to assess the efficacy of Tappt at enabling pharmacists to personalize treatment and management decision based on participants' reported barriers to adherence, care, and SVR achievement.

Participants will download and utilize the Tappt app to record adherence to oral medication. For the purposes of this study, adherence for participants in the intervention arm will be measured using a modified medication possession ratio (MPR) measure called medication tag scan ratio (MTSR). MTSR is defined as a percentage of the number of times participants scanned their passive tags versus the total of expected tag scans based on that participant's medication regimen and treatment period.

Upon study completion, a retrospective matched control will be established for the intervention group. Historic data for the matched control's adherence, treatment completion, SVR assessment, and SVR rates will be compared to the intervention arm.

Tappt App

Experimental group

Description:

Participants will download and utilize the Tappt app to record adherence to oral medication. For the purposes of this study, adherence for participants in the intervention arm will be measured using a modified medication possession ratio (MPR) measure called medication tag scan ratio (MTSR). MTSR is defined as a percentage of the number of times participants scanned their passive tags versus the total of expected tag scans based on that participant's medication regimen and treatment period.

Other: Use of Tappt App

Historical Control

No Intervention group

Description:

Upon study completion, a retrospective matched control will be established for the intervention group. Historic data for the matched control's adherence, treatment completion, SVR assessment, and SVR rates will be compared to the intervention arm.
