A Phase 1/2a, Sequential Cohort, Single Ascending Dose Study of the Safety, Tolerability, Biodistribution, and Pharmacodynamics of EBT 101 in Aviremic HIV-1 Infected Adults on Stable Antiretroviral Therapy

This is a FIH, open-label, sequential cohort, single ascending dose (SAD) study of EBT-101 administered IV to aviremic HIV-1 infected adults on stable ART.

Participants will be asked to attend several visits for screening to determine eligibility. On Day 1, eligible participants will receive a single IV dose of EBT-101. All participants will be assessed for eligibility for an analytical treatment interruption (ATI) of their background ART at Week 12. All participants will be followed through Week 48 (end of study). Participants are required to attend multiple study visits at the clinical site including daily visits for the first 14 days, followed by weekly visits after Week 12 for ATI participants. Non-ATI participants are followed monthly after Week 12.

Eligible participants who are enrolled in the FIH study (EBT-101-001) will also be enrolled in a separate Long Term Follow Up (LTFU) study (EBT-101-002) for safety monitoring. The duration of the LTFU study is 15 years.
