N-803 Combined With the Broadly Neutralizing Antibodies Plus or Minus haNK Cells for HIV

HIV Infections Clinical Trial

Official title:
A Phase 1B Study of N-803 Combined With the Broadly Neutralizing Antibodies VRC07-523LS and PGT121 Plus or Minus haNK Cells for Reduction of HIV Reservoirs

Clinical Trial Summary

To assess the safety of combination immune therapy in HIV-infected participants whose HIV is controlled with ART, by determining the incidence and severity of adverse events.

Clinical Trial Description

This is a phase 1b study to examine the safety, tolerability and efficacy of the combination of 4 immunotherapies for treatment of HIV in participants with controlled HIV viremia and stable CD4 counts on antiretroviral therapy (ART). The study will be conducted in two separate phases using two distinct to groups of participants where each group will have 10 individuals enrolled. Treatment will consist of N-803, VRC07-523LS, PGT121, and haNK, with N-803 given for 3 cycles of 9 weeks/cycle. N-803 will be given every 3 weeks (3 doses/cycle), bNAbs will be given every 9 weeks, and haNK cells administered on the same day as each infusion of N-803. Total study duration will be 27 weeks. Group 1 will receive only N-803 and the bNAbs; they will not receive the haNK™ cells. When 2 participants are enrolled and on active treatment for one month in Group 1, the Safety Monitoring Committee will review all data and if there are no safety concerns raised in the data recorded from administration of the interventions to those participants, Group 1 will continue. When Group 1 is complete, the SMC will again review all data before Group 2 can proceed with enrollment. The protocol for Group 2 will be identical to the one followed by Group 1, except that they will receive haNK™ cells at 2 × 109 cells/dose IV on the same day as each dose of N-803. Optional tissue biopsies (lymph node and colonoscopy to collect gut-associated lymphoid tissue (GALT)) will occur at baseline and again 9 weeks after the last infusion of bNAbs. We aim to perform biopsies on least 8 out of 10 participants in each group. ;
