Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hair samples from subjects on antiretroviral therapy, both HIV- and HIV+ patients with HIV RNA \<50copies/mL for \>6 months will be analyzed to investigate the influence of race, hair color and hair treatment on ARV response.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A small thatch of hair (approximately 20 strands) will be collected from 85 participants who are currently taking antiretrovirals (ARVs). Hair collection will be evenly distributed into color cohorts: Black, Brown, Blonde and Grey. Participants will need to be \>80% adherent to their medication and have had an undetectable HIV RNA VL within the previous 6 months. In the lab, samples will be used to develop IR-MALDESI MSI hair protocols for high sensitivity and accuracy to quantify ARVs in 5 therapeutic drug classes (Integrase Inhibitors, Nucleoside Reverse Transcriptase Inhibitors, Non-Nucleoside Reverse Transcriptase Inhibitors, Entry Inhibitors, Protease Inhibitors).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

HIV negative and positive individuals

HIV Negative or HIV positive individuals, aged 18 years or older, who have been taking their ARV medication for at least 3 months and are adherent based on blood plasma HIV RNA of \<50 copies/mL or HIV negative status. Hair analysis.

Hair analysis

Intervention Type OTHER

Within the laboratory, experimental factors controlling IR-MALDESI response to key ARVs representing various drug classes will be systematically evaluated using the design of experiments (DOE) statistical approach (41,127) for an unbiased optimization of IRMALDESI response to each of the ARVs and their major metabolites. The goal will be to achieve a lower limit of quantification (LLOQ) below clinically relevant hair strand concentrations.
