Summary

Maraviroc, a C-C Chemokine Receptor 5 (CCR5) antagonist, is well-tolerated without significant side effects in its current use in patients with HIV. CCR5 antagonism prior to the 'second wave' of inflammatory mediator expression in SARS-CoV-2 may reverse lymphoid depletion and may alter cell trafficking of inflammatory cells, both increasing viral control capacity and dampening damage to lung tissue, respectively. This study seeks to establish whether one week of treatment with Maraviroc, used at its approved dosage for HIV, is safe and tolerable in patients with SARS-CoV-2.

Detailed description

This pilot study seeks to establish that selective blockade of the CCR5/CCL5 axis as well as the potential anti-viral properties of Maraviroc may reduce disease severity. This proof-of-concept effort seeks to correlate differences in clinical outcomes to differential cytokine expression in the setting of CCR5 antagonism in patients infected with SARS-CoV-2. Maraviroc is FDA-approved for the treatment of CCR5-tropic HIV-1 and has a well-documented safety and tolerability record in previous trials in immunocompromised HIV patients. Maraviroc was not shown to have significant effect on the QT segment, can be delivered via oral formulation, and can be delivered safely to both patients with end-stage renal disease and dependence on hemodialysis12. For these reasons, Maraviroc is an ideal candidate to study as a potential therapy for hospitalized patients with moderate-to-severe COVID-19. The primary objective is to establish whether Maraviroc, used at its approved dosage for HIV, is safe, tolerable, and effective in hospitalized patients with SARS-CoV-2. The secondary objective is to investigate the relationship between reduction of inflammatory markers (such as IL-6, CCL5, etc.) and clinical outcomes, including avoidance of respiratory decompensation and death. This is a single-center, single-arm, open-label trial. Sixteen hospitalized patients will be enrolled. Screening data will be reviewed to determine subject eligibility. Subjects who meet all inclusion criteria and none of the exclusion criteria will be approached for consent prior to entering the study. Each subject will receive 7 days of Maraviroc twice daily. Each subject will have blood samples checked at time of enrollment (Day 0), Day 3, Day 7, and Day 15 or time of live discharge (whichever comes first) of the study. The total duration of subject participation will be five weeks. The total duration of the study is expected to be 16 weeks.
