Effect of N-803 on B Cell Follicles in Antiretroviral Treated HIV Disease

Inclusion Criteria

• HIV-1 infection, documented by any licensed rapid HIV test or HIV enzyme or chemiluminescence immunoassay (E/CIA) test kit at any time prior to study entry and confirmed by a licensed Western blot or a second antibody test by a method other than the initial rapid HIV and/or E/CIA, or by HIV-1 antigen or plasma HIV-1 RNA viral load.
• On continuous antiretroviral therapy for over 24 months without any interruptions of greater than 14 consecutive days, without plans to modify ARTduring the study period.
• Screening plasma HIV RNA levels 200 per participant report.
• Ability to be off prednisone and other immunosuppressive drugs for at least 14 days before screen. Inhaled, nasal spray, and topical steroids are acceptable.
• Acceptable blood pressure and heart rate parameters within normal limits (systolic = 88-140mmHg; diastolic = 50- 12.5 g/dL for men and > 11.5 g/dL for women. It is not acceptable for patients to be transfused to meet this requirement. The use of Epogen is permitted.
• Estimated Cr Cl (eGFR) > 50

Exclusion Criteria

• Active or recent malignancy requiring systemic chemotherapy or surgery in the preceding 36 months or for whom such therapies are expected in the subsequent 12 months; minor surgical removal of localized skin cancers (squamous cell carcinoma, basal cell carcinoma) are not exclusionary
• Chronic liver disease defined as Class B and C on the Child-Pugh chronic liver disease scale.
• Active and poorly controlled atherosclerotic cardiovascular disease (ASCVD), as defined by 2013 ACC/AHA guidelines, including a previous diagnosis of any of the following:
• acute myocardial infarction
• acute coronary syndromes
• stable or unstable angina
• coronary or other arterial revascularization
• stroke
• transient ischemic attack (TIA)
• peripheral arterial disease presumed to be of atherosclerotic origin.
• History of potential immune-mediated medical conditions requiring concomitant treatment with immunomodulatory drugs, and/or exposure to any immunomodulatory drug in the 30 days prior to screen (e.g. corticosteroid therapy equal to or exceeding a dose of 15 mg/day of prednisone for more than 10 days, IL-2, interferon, methotrexate, cancer chemotherapy). NOTE: use of inhaled, nasal steroid or topical steroid lotions and creams is not exclusionary. Prior exposure to N-803 is not exclusionary if prior exposure occurred at least 6 months before screen.
• Unable to undergo leukapheresis procedure
• Exposure to any experimental therapies within 90 days of study screen. Exposure to long acting injectable ART therapies is not exclusionary.
• Latent TB infection or active TB disease prior to completing a standard regimen of anti-TB therapy that is defined as meeting PPD criteria for TB exposure or a positive quantiferon gold test collected at screening.
• Active fungal infection requiring systemic antifungal therapy
• Active herpes outbreak or varicella-zoster virus infection requiring episodic treatment
• Chronic active hepatitis B or C. For Hepatitis B this will be defined as HBs antigen + and for Hepatitis C this will be defined as Hepatitis C antibody positive and Hepatitis C PCR+.
• History and/or presence of any clinically significant disease or disorder, such as cardiovascular, pulmonary, renal, hepatic, neurological, gastrointestinal and psychiatric/mental disease/disorder, which, in the opinion of the site Principle Investigator may either put the subject at risk because of participation in the study, influence the results of the study or the subject's ability to participate in the study.
• Any degree of baseline QT/QTc interval prolongation (QTc interval > 450 msec in males and > 470 msec in females.)
• Any ischemic changes seen in the stress treadmill test administered per the discretion of the PI in order to assess any other EKG abnormalities outlined in study protocol
• History or evidence of uncontrollable CNS disease such as dementia, demyelinating disease, Parkinson's,
