Official title

A Phase 1 Study of MGD020 as a Single Agent or in Combination With MGD014 in Persons With HIV-1 on Antiretroviral Therapy

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Study CP-MGD020-01 is a phase 1, open-label, dose-escalation, and multi-dose expansion study of MGD020 as a single agent or in combination with MGD014 in persons with HIV-1 (PWH) on antiretroviral therapy (ART). The study is designed to evaluate the safety, tolerability, pharmacokinetics (PK), immunogenicity, and pharmacodynamics (PD) of the study drugs. The study consists of 3 parts (Part 1A, Part 1B, and Part 2). The participant's standard of care ART regimen is continued throughout the study period. MGD020 is a bispecific DART® molecule that binds CD3 and gp41 subunit of HIV-1 envelope. MGD014 is a bispecific DART® molecule that binds CD3 and gp120 subunit of HIV-1 envelope. These DART molecules redirect CD3+ T lymphocytes to kill HIV-1-infected CD4+ T cells. Part 1A evaluates groups of participants given a single dose of MGD020. A 2-week safety period is observed prior to escalation to the next dose level. Dose escalation continues until either the maximum tolerated dose (MTD) or maximum administered dose (MAD) is determined. Part 1B begins after the end of Part 1A. Part 1B evaluates groups of participants given a single dose of the MGD020 MTD or MAD from Part 1A and a fixed dose of of MGD014. The first group will be treated with a single dose of MGD020, at a dose determined to be one dose lower than the single-agent MTD/MAD from Part 1A, and a single 300 mcg/kg dose of MGD014. Dose escalation proceeds until either the MTD or MAD is determined. Part 2 begins after the end of Part 1B. Part 2 is a multi-dose expansion group. Each participant will receive the MTD or MAD of MGD020 from Part 1B and a fixed dose of MGD014 from Part 1B, administered every 2 weeks (Q2W) for 3 combination doses over 4 weeks. Up to 6 participants may be enrolled in Part 2.
