Official title
HIV Outpatient Monitoring Evaluation Through Self-collection of Dried Blood Spots (HOME-1)
Overview
The goal of this observational study is to establish an operational framework for home self-collections of blood samples to be used for antiviral drug concentration measurements. Participants will continue on their prescribed antiviral(s) for HIV treatment or prevention and followed for up to approximately 1 year. The investigators will compare drug concentrations of antivirals and relevant metabolites/anabolites in clinic-collected and self-collected blood samples.
Detailed description
Up to 150 people receiving care at the UCH-IDGP will be enrolled in the study at a routine clinic visit where a standard of care (SOC) blood collection and/or SOC dose of LA antivirals (e.g., LA IM CAB±RPV) is planned. Once consented, demographic and clinical data will be obtained. Clinical data that will be collected from participant and medical records may include: age, sex at birth and gender identity, race, ethnicity, medication history, duration of current antiviral therapy, hematocrit, CD4+ T-cell count, HIV VL, and self-reported adherence.
The investigators will collect an extra \~5 mL of blood in EDTA by venipuncture for DBS, plasma, whole blood, and blood cells at each clinic-collection visit. At the first clinic-collection visit, participants will be given home self-collection kits and instructed to self-collect samples at various timepoints prior to their next injection (if on LA antivirals), monitored by live video-streaming or time-stamped video. The investigators will go through how to self-collect, handle, and mail the blood samples by self-collecting together in the clinic (in-person training), and participants will be asked about their medical history and medications.
Participants on PO antivirals (e.g., TFV/FTC) may only complete one clinic-collection visit (and one at-home self-collection). At home self-collections and clinic-collections may continue for participants on LA antivirals (e.g., LA IM CAB±RPV) for up to approximately 1 year. All study visits will be linked to SOC visits; there will be no additional visits to the clinic beyond what is already required for SOC:
* If continuing prescribed Q8W injections, up to 7 SOC clinic visits at (approximately) weeks 0, 8, 16, 24, 32, 40, and 48 * If initiating prescribed Q8W injections, up to 7 SOC clinic visits at (approximately) weeks 0, 4, 12, 20, 28, 36, and 44 * If continuing or initiating prescribed Q4W injections, up to 13 SOC clinic visits at (approximately) weeks 0, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and 48 * If continuing or initiating prescribed Q26W injections, up to 3 SOC clinic visits at (approximately) weeks 0, 26, and 52
Participants will be asked to self-collect samples at home by two or more methods (self-collection kits): fingerstick and spotting onto Whatman 903 protein saver card, and/or use of one or more self-collection devices (e.g., Tasso-M20/Tasso+, Mitra, others). After sample collection, samples/devices will be shipped back to our laboratory in their provided box(es). All samples obtained by self-collection methods/devices are approved for shipping via mail or other carriers in the US. Participants may complete up to 25 at home self-collections (approximately once biweekly for the participants followed longitudinally).
Interventions
- Other At Home Self-Collections
Directly observed at home self-collection of blood samples
Primary outcome measures
- Agreement of drug concentrations of antivirals and relevant metabolites/anabolites in blood samples [Time frame: Up to approximately 1 year]
Secondary outcome measures (2)
- Acceptability of at home self-collection of blood samples [Time frame: One-time, approximately 1-2 weeks after first clinic-collection visit]
- Feasibility of at home self-collection of blood samples [Time frame: One-time, approximately 1-2 weeks after first clinic-collection visit]
Eligibility criteria
Inclusion criteria
- ≥18 years old
- Receiving one or more antivirals for HIV treatment or prevention. This may include TFV (as TDF or TAF) and FTC (or 3TC)-based, LA (e.g., LA IM CAB±RPV Q4W or Q8W), or other antivirals (those who are transitioning to LA antivirals \[e.g., LA IM CAB±RPV Q4W or Q8W\] will also be eligible)
- Current patient at the UCH-IDGP clinic
- Able to comply with study procedures, including directly observed self-collection of DBS by fingerstick, Tasso-M20/Tasso+, Mitra, and/or other self-collection methods/devices, and completion of survey
Exclusion criteria
- Inability to provide informed consent
- Unable or unwilling to comply with directly observed self-collection of DBS (e.g., unavailable or unable to use live video-streaming or time-stamped video recording technology)
- Any uncontrolled medical, social, or mental health issue(s) that, in the opinion of the investigators, could interfere with the study participation or study outcomes (e.g., current incarceration)
- Any medical condition that, in the opinion of the study team, acutely and/or transiently influences the PK of CAB±RPV, including acute kidney injury, hepatic insufficiency, significant drug-drug interactions, active hemolysis or symptomatic hemoglobinopathies, etc. (Note: Given the need for PK data in pregnancy, women who become pregnant while on LA IM CAB±RPV Q4W or Q8W will be allowed to participate in this study, if their clinical provider decides to continue this regimen.)
