Clinical Trial Summary

Darunavir/cobicistat/emtricitabine/tenofovir alafenamide (DRV/COB/FTC/TAF) is a coformulated STR, is the only protease inhibitor based STR, and is noted for its high tolerability3. These traits have the potential to improve adherence in patients who have intolerance to the integrase inhibitor class. We propose a two part study design to evaluate if patients who have suboptimal adherence due to integrase inhibitor intolerance may better tolerate Symtuza and subsequently have improved adherence.


Description:

With the advent of anti-retroviral therapy, HIV transformed into a manageable chronic disease for patients who were able to obtain medications, provided they could remain adherent to them. When single tablet regimens (STR) became available, adherence to HIV medications was made easier for many patients. However even years after STR became available, 38% of patients reported they do not maintain optimal adherence to their HIV medications. While there are many factors that contribute to this problem, medication intolerance contributes to suboptimal adherence for many patients Darunavir/cobicistat/emtricitabine/tenofovir alafenamide (Symtuza) is a coformulated STR, is the only protease inhibitor based STR, and is noted for its high tolerability. This trait has the potential to improve adherence in patients who have intolerance to the integrase inhibitor class. We are not aware of any studies that have examined this potential and find that information gap worth investigating. We propose a two part study design to evaluate if patients who have suboptimal adherence due to integrase inhibitor intolerance may have better tolerability to Symtuza and subsequently have improved adherence. The initial portion of the study will consist of a self-administered adherence survey offered over a 4 month period to established patients at Midland Medical Center who are HIV+, regardless of disease state or regimen. Subjects who self-identify as non-adherent due to tolerability issues will be screened for enrollment in the primary study. Subjects found to be non-adherent due to other issues will be referred back to their provider. Subjects who are referred for screening who are on an integrase inhibitor and who do not have a contraindication will be enrolled, will complete a Patient Reported Outcome survey (PRO) to assess side effects/quality of life, and switched to Symtuza. Subjects who are not enrolled in the study will be referred back to their provider to address the issues with tolerance and adherence. Subjects will be followed for 4 months. During that period, they will be brought back for evaluation at the end of the first month and the end of the fourth month. At those evaluations, they will again complete the PRO and adherence surveys to assess tolerability and adherence. At the evaluations, they will also be monitored for safety and effectiveness via physical exams and laboratory studies (Complete Blood Count, Complete Metabolic Panel, Urinalysis, CD4 panel, HIV1 Quantitative viral load). The de-identified laboratory and survey results from the baseline and subsequent assessments will be turned over to a statistician to evaluate changes in adherence, tolerability, effectiveness, and safety.

Outcome

Type Measure Description Time frame Safety issue
Primary Part 1 of the study is a cohort survey of change in adherence, tolerability and safety of subjects who report poor adherence to ART due to intolerance/side effects from integrase inhibitor containing regimens. To evaluate trends and patterns in subjects who report sub-optimal adherence, analyzed by intention to treat with Integrase Inhibitor based Antiretroviral containing regimens, based upon the subjects completion of the Midland ART Adherence Survey (MAAS) 4 months
Secondary To determine potential changes in ART adherence in subjects who report sub-optimal adherence due to side effects from integrase containing regimens after switching to Symtuza. Sub-optimal adherence will be determined by comparing the study subjects completed Midland ART Adherence Survey at the week 4 visit to the week 16 visit to the number of the investigational product (Symtuza) tablets that are counted at week 4 visit and week 16 visit.
Each dispensed bottle of IP (Symtuza) will contain 30 tablets.
4 months
Secondary To evaluate the tolerability of switching from an integrase inhibitor containing regimen to Symtuza. We will be using the standardized Patient Reported Outcomes (PRO) questionnaire to determine a percentage of subjects who report suboptimal adherence due to tolerance issues/side effects and those who report suboptimal adherence due to reasons other than tolerance issues/side effects. 4 months
Secondary Safety and efficacy of switching from integrase inhibitor containing regimen to Symtuza as determined by the proportion of subjects with virologic failure, a change in laboratory parameters and change in CD4 cell count from baseline. We will be looking at the proportion of subjects that have an HIV-1 RNA = 50 copies/mL at baseline and at week 16 and comparing them to the subjects level of ART adherence.
There will be an assessment of whether or not there are any significant laboratory changes in subjects serum Creatinine- (0.70-1.33 mg/dL) , AST- (10-35 u/L) and ALT-(9-46 u/L) when compared to week 16 from the baseline evaluation.
We will compare any laboratory changes in the subjects Absolute CD4+ cell count- (490-1740 cells/uL) along with the % of CD4 cells- (30-61%) from the subjects week 16 laboratory levels to the baseline assessment by using the study site determined laboratory.
4 months
Secondary To evaluate for potential weight loss when switching from integrase inhibitor containing regimen to Symtuza. There will be an assessment of the subjects weight in kilograms- (kg) from the initial baseline visit to the week 16 visit with recorded BMI.
Initial subjects Body Mass Index (BMI) will be assessed by using the formula: weight (kg) / [height (m)]2
The World Health Organization's (WHO) recommended body weight based on BMI values for adults will be referenced.
Category BMI range - kg/m2 Severe Thinness < 16 Moderate Thinness 16 - 17 Mild Thinness 17 - 18.5 Normal 18.5 - 25 Overweight 25 - 30 Obese Class I 30 - 35 Obese Class II 35 - 40 Obese Class III > 40
