Clinical Trial Summary

This is a prospective, non-interventional, multi-center study, in subjects with clinical indication of Human Immunodeficiency Virus (HIV)-1 infection. The aim of the study is to generate the real world evidence for the use of DTG+3TC in routine clinical care in Germany to supplement data obtained from controlled clinical trials. Approximately, 300 treatment naïve and pre-treated HIV-1 positive subjects will be enrolled in the study. The observation period for the study will be 3 years. Data will be collected from routine clinical care via electronic data capture (EDC) system.

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of subjects with sustained virologic suppression, with Viral load (VL) < 50 Copies per Milliliter (c/mL)	Percentage of subjects with sustained virologic suppression, defined as VL <50 c/mL or if between 50-200 c/mL with a subsequent next available measurement <50 c/mL (within 120 days) will be evaluated.	Up to 36 months
Secondary	Percentage of pre-treated subjects with low level viremia	Percentage of subjects with low level viremia, defined as a VL measurement between >50 to <200 c/mL for pre-treated subjects will be evaluated.	Up to 36 months
Secondary	Percentage of naïve subjects with low level viremia after initial suppression	Percentage of subjects with low level viremia, defined as a VL measurement between >50 to <200 c/mL after initial suppression of <50 c/mL for naïve subjects will be evaluated.	Up to 36 months
Secondary	Percentage of virologic non-responders for naïve subjects	Percentage of virologic non-responders, defined as two consecutive measurements >=200 c/mL after at least 24 weeks of treatment in naïve subjects will be evaluated.	Up to 36 months
Secondary	Percentage of naïve subjects with virologic rebound	Percentage of naïve subjects with virologic rebound, defined as two consecutive VL measurements >=200 c/mL after suppression (one VL <50 c/mL) will be evaluated.	Up to 36 months
Secondary	Percentage of subjects with VL < 50 c/mL	Percentage of subjects with VL <50 c/mL will be evaluated.	Up to 36 months
Secondary	Percentage of subjects with two consecutive VL measurements of >=200 c/mL	Percentage of subjects with two consecutive VL measurements of >=200 c/mL will be evaluated.	Up to 36 months
Secondary	Percentage of subjects with treatment switch	Percentage of subjects with treatment switch due to virologic failure (VF) or due to intolerability determined at the discretion of the physician will be evaluated.	Up to 36 months
Secondary	Percentage of subjects with VL > 50 c/mL with emergent resistance mutations	Percentage of subjects with VL >50 c/mL with emergent resistance mutations will be summarized. Resistance analysis will be performed at the physician's discretion.	Up to 36 months
Secondary	Number of monitoring measures	Number of monitoring measures (normalized to subject years) will be summarized.	Up to 36 months
Secondary	Number and frequency of serious adverse events (SAE)	An SAE is any untoward medical occurrence that, at any dose results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect or is medically significant.	Up to 36 months
Secondary	Number and frequency of adverse drug reactions (ADRs)	An ADR is defined as a noxious and unintended response to a medicinal investigational product related to any dose where at least a reasonable possibility, that is the relationship cannot be ruled out.	Up to 36 months
Secondary	Adherence to therapy	Adherence to therapy will be determined from the number of monthly doses missed.	Up to 36 months

Secondary	Change from Baseline for lipid laboratory parameters: cholesterol and triglycerides	Lipid laboratory parameters cholesterol and triglycerides data will be evaluated at indicated time points.	Baseline and up to 36 months
Secondary	Change in treatment satisfaction based on HIV Treatment Satisfaction questionnaire (HIV TSQ)	The HIV TSQ is a 10-item-self-reported scale that measures overall satisfaction with treatment and by specific domains e.g., convenience and flexibility. In treatment satisfaction score will range from 0-60, higher the score, greater the satisfaction with treatment. Individual item scores which included All rate score ranging from 0 (very dissatisfied, inconvenient, inflexible) to 6 (very satisfied, convenient, flexible), in case of general satisfaction , there will be 10 items which will be summed to produce a score ranging from 0 to 30, with higher the score greater the satisfaction with subscale. For lifestyle scale with 8 items which will be summed to produce a score ranging from 0 to 30, with higher the score greater the satisfaction with subscale.	Up to 36 months
Secondary	Change in Symptom Distress based on HIV Symptom Distress Module questionnaire	The Symptom Distress Module is a 20-item self-reported measure that addresses the presence and perceived distress linked to symptoms commonly associated with HIV or its treatment. This included sub-scales change in treatment satisfaction, individual satisfaction with treatment change. Treatment satisfaction score summed all items to produce scores ranging from +30 to -30, higher the score, greater the improvement in satisfaction with treatment, lower score greater is the deterioration in satisfaction. Individual item scores which included All rate score ranging from +3 (much more satisfied, much more convenient, much more flexible) to -3 (much less satisfied, much less convenient, much less flexible). General satisfaction and life style scores all items summed to produce score range +15 to -15, where higher the score greater the improvement in satisfaction, lower score greater is the deterioration in satisfaction.
