People with HIV usually take a combination of 2 or more anti-HIV drugs daily to help manage their infection. Sometimes, however, HIV becomes resistant to these drugs, and the infection cannot be treated. Untreated HIV infection can make people more vulnerable to other infections as well as some cancers. Better treatments are needed for people with drug-resistant HIV.
Objective:
To see if a study drug (UB-421) is effective in people with drug-resistant HIV.
Eligibility:
People aged 18 years and older with HIV that is resistant to anti-HIV drugs.
Design:
Participants will be in the study for 35 weeks.
Participants will have separate screening and baseline visits within 2 months of each other. They will have a physical exam with blood and urine tests both times. On the second visit, they will undergo apheresis: Blood will be drawn from a needle in one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be given back through a second needle in the other arm.
Participants will begin receiving the study drug 1 week after their baseline visit. UB-421 is given through a tube attached to a needle placed in a vein in the arm. They will return for UB-421 treatments every week for 26 weeks. Each visit will take 3 to 6 hours.
Participants will have 2 follow-up visits 4 and 8 weeks after their last treatment with UB-421. Apheresis will be repeated at 1 of these visits.

INCLUSION CRITERIA: In order to be eligible to participate in this study, an individual must meet all of the following criteria: -Ability to provide informed consent; -Stated willingness to comply with all study procedures and availability for the duration of the study; -Aged 18 years or older; -Have a life expectancy that is >6 months (as judged by the Principal Investigator [PI]); -HIV-1 seropositive; -Have a history of being treated for at least 6 months with ART; -Plasma HIV-1 RNA >= 1,000 copies/mL at the Screening visit; -Screening CD4+ T cell counts of > 350 cells/mm3; -Documented genotypic or phenotypic resistance to at least one ARV drug within three or more drug classes of ARV medications; -Receiving a stable failing regimen of cART for at least 8 weeks before Screening and are willing to continue the failing regimen during the Screening Phase and up to study day 21 of the Treatment Phase, OR have failed a regimen within 8 weeks of Screening, are off ART and are willing to stay off ART until day 21 of the Treatment Phase. Patients who failed to attain or maintain complete suppression of plasma viremia while receiving fostemsavir will not be allowed to enroll in the study. Patients who failed to attain or maintain complete suppression of plasma viremia while receiving ibalizumab-based salvage regimen will be allowed to enroll in this study; however, prior ibalizumab use must have ended at least five half-lives (i.e., 21 days) before the first dose of UB-421; -Have viral sensitivity to at least one FDA-approved ARV agent, as determined by genotypic or phenotypic ARV drug resistance testing, and such agent can be used as a component of OBT. Patients currently receiving enfuvirtide, ibalizumab, or maraviroc will be excluded from this study, unless patients agree to discontinue these drugs for at least five half-lives (i.e., 1 day, 21 days or 4 days, respectively), before the first dose of UB-421. These drugs also will not be allowed as a component of OBT; -Be willing to remain on treatment without any changes or additions to the OBT regimen, except for toxicity management or upon meeting criteria for treatment failure; -For females of reproductive potential: use of highly effective contraception - as detailed in the Centers for Disease Control and Prevention (CDC) US Selected Practice Recommendations for Contraceptive Use (US SPR) - for at least 1 month prior to Baseline visit and agreement to use such a method during study participation and for an additional 4 weeks after the end of UB-421 administration. For males of reproductive potential, for at least 1 month prior to Baseline visit and agreement to use such a method during study participation and for an additional 4 weeks after the end of UB-421 administration: use of condoms or other methods to ensure effective contraception with partner of childbearing potential; Non-reproductive potential is defined as azoospermia, postmenopausal, surgical sterilization at least 6 weeks before screening, or a congenital or acquired condition that definitively prevents conception. Further, postmenopausal is defined as at least 12 consecutive months with no menses at age 50 or older, and also a high follicle-stimulating hormone level in postmenopausal range at ages 45-50 years, for participants not using hormonal contraception or hormone replacement therapy. Participants of reproductive potential must either practice complete and uninterrupted abstinence from heterosexual activity or use two of the following methods of contraception with their partners. The 2 methods must include one from each group, both of which must be consistently use: Barrier methods: --Diaphragm with spermicide (cannot be used in conjunction with cervical cap/spermicide). --Cervical cap with spermicide (only for nulliparous partners). --Contraceptive sponge (only for nulliparous partners). --Male or female condom (cannot be used together). Non-barrier methods: --Intrauterine device. --Hormonal contraception: pill (estrogen/progestin or progestin-only), skin patch, vaginal ring, rod implanted in the skin, or subcutaneous injection. -Laboratory values at Screening of: --Absolute neutrophil count (ANC) >= 750/mm3; --Hemoglobin (Hb) >= 10.5 gm/dL (male) or >= 9.5 gm/dL (female); --Platelets >= 50,000 /mm3; --Serum alanine transaminase (ALT) < 2.5 x upper limit of normal (ULN); --Serum AST < 2.5 x ULN; --Bilirubin (total) < 2.5 x ULN (Exceptions: Gilbert's disease, or the subject is receiving atazanavir and there is no evidence of significant liver disease); --Estimated or a measured glomerular filtration rate >60 mL/min/1.73 m2 as determined by the NIH CC laboratory.
