Brief Summary
Reducing HIV persistence in lymph nodes by Interleukin-15 (IL-15) Receptor super-agonist (N-803) in Individuals with Acute HIV Infection
Detailed Description
This is a phase II, randomized, unblinded, controlled trial to investigate the safety, tolerability and immunomodulation effect of combining N-803 with ART during AHI. The study will be conducted at t...
Eligibility Criteria
Inclusion
- Inclusion Criteria for step 1:
- Age 18 years and above.
- Acute HIV infection (Fiebig I to V: Fiebig I: RNA+, p24 antigen-; Fiebig II: p24 antigen+, IgM-; Fiebig III: IgM+, Western Blot-; Fiebig IV: Western Blot indeterminate; Fiebig V: Western Blot+ without p31 protein band)
- All female participants of childbearing potential must have a negative urine pregnancy test at the screening visit
- Women of child bearing potential and men with partners of child bearing potential must agree to use effective contraception (as defined in section 8.1.2 Pregnancy Risks) during therapy and for 4 months after completion of therapy
- Can read and write Thai and/or English language and must be able to understand and complete the informed consent process
- Must successfully complete a Test of Understanding (TOU) prior to enrollment as described in Section 7.1
- Willing to undergo inguinal LN Bx at two time points (baseline and week 6) and blood draws during each study visit
- Willing to participate for the duration of the study visits and follow up.
- Exclusion Criteria for step 1:
- Pregnant, breastfeeding, or unwilling to practice birth control during participation in the study
- 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
- Receipt of any vaccine within 2 weeks prior to study enrollment and anticipated need for any vaccine within 2 weeks prior to or after any of the study agent administrations.
- Current or anticipated use of systemic steroid medications.
- Any clinically significant acute or chronic medical condition, including, pulmonary, hepatic, renal, gastrointestinal, genitourinary, hematological, coagulation, that in the opinion of the investigator would preclude participation (e.g., history of seizure disorders, cardiac disease, bleeding/clotting disorder, autoimmune disease, active malignancy, poorly controlled asthma, active tuberculosis or other systemic infections, etc.)
- Chronic liver disease
- Active and poorly controlled atherosclerotic cardiovascular disease (ASCVD), as defined by 2013 ACC/AHA guidelines, including a previous diagnosis of any of the following: (a) acute myocardial infarction, (b) acute coronary syndromes, (c) stable or unstable angina, (d) coronary or other arterial revascularization, (e) stroke, (f) transient ischemic attack, or (g) peripheral arterial disease presumed to be of atherosclerotic origin
- History of potential immune-mediated medical conditions
- Serious illness requiring systemic treatment and/or hospitalization in the 3 months prior to study enrollment
- Major psychiatric illness and/or substance use during the past 12 months that in the opinion of the investigator would preclude participation
- Concurrent treatment with immunomodulatory drugs, and/or exposure to any immunomodulatory drug in the 4 weeks prior to study enrollment
- Exposure to any experimental therapies within 90 days of study entry
- Pre-exposure prophylaxis (PrEP) use within 90 days of study entry
- Inclusion criteria for Step 2:
- Completed Step 1 as per protocol
- Plasma HIV-1 RNA \<50 copies/mL at the Step 2 screening visit
- CD4 T-cell count ≥400 cells/mm3 at the Step 2 screening visit Note: The CD4 T-cell count can be repeated once, provided that the repeat is done within 1 week prior to Step 2 entry.
- No CDC Category C event after study entry
- Documented negative hepatitis B virus (HBV) surface antigen (HBsAg) at the screening Step 2 visit.
- Documented negative hepatitis C virus (HCV) antibody (anti-HCV) or negative HCV RNA (if anti-HCV reactive) at the Step 2 screening visit
- For persons of childbearing potential, negative pregnancy test at the Step 2 screening visit.
- Persons of childbearing potential must agree to not become pregnant and use two methods of contraception if engaging in sexual activity that could lead to pregnancy. One contraceptive method must be from the list of highly effective methods listed in section 7.12. The second method of contraception must be from the barrier methods also listed in section 7.13.
- Willingness to abstain from sexual intercourse, or use a condom, or partner(s) using pre-exposure prophylaxis consistently during ATI and until plasma HIV-1 RNA is less than limit of detection after ART restart with all partners that are HIV-uninfected or serostatus unknown.
- Willingness to participate in ATI for up to 12 weeks.
- Willingness to restart ART according to study guidelines.
- Exclusion Criteria for Step 2 ATI
- Virologic failure (two consecutive HIV-1 RNA \>1000 copies/mL)
- Intercurrent illness, new medical diagnosis, laboratory abnormality, sign, or symptom that, in the opinion of the site investigator, would place participant at higher risk of morbidity during ATI.
- Receipt of any non-nucleoside reverse transcriptase inhibitor (NNRTI) within 60 days before Step 2 entry.
- Receipt of long-acting ART such as long-acting cabotegravir (CAB LA) or long-acting rilpivirine (RPV LA) at any point after study entry.
- Failure by the participant to attend three consecutive Step 1 study visits.
- Pregnancy or breastfeeding.
- Active drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements.
