RECRUITING

Imaging Immune Activation in HIV by PET-MR

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a single center exploratory imaging study involving one intravenous microdose of \[18F\]F-AraG followed by whole-body positron emission tomography-magnetic resonance (PET-MR) imaging in HIV infected individuals to determine the anatomical distribution of the PET tracer. Participants will be enrolled if they were treated during early or late HIV infection. In addition, individuals not on antiretroviral therapy (ART) or with HIV-1 plasma RNA levels \>5,000 copies/mL will be enrolled. Up to 30 participants will be enrolled with HIV.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:18 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. 1. Age \>18 years
  2. 2. Ability to read and understand written informed consent document
  3. 3. HIV infection, and Initiated a combination ART regimen, or, has never received ART, or, has received ART in the past, but has not been taking for a least 1 week prior to study imaging.
  4. 4. Laboratory evaluations obtained within 60 days prior to entry. i. Platelet count ≥100,000/mm3 ii. ANC \>1500/mm3 iii. Aspartate aminotransferase (AST) \<2 x ULN iv. Alanine aminotransferase (ALT) \<2 x ULN v. CD4+ T cell count \>100 cells/mm3 for HIV infected individuals vi. Calculated creatinine clearance (CrCl) ≥60 mL/min as estimated by the Cockcroft-Gault equation: For men, (140 - age in years) x (body weight in kg) ÷ (serum creatinine in mg/dL x 72) = CrCl (mL/min)\*
  5. * For women, multiply the result by 0.85 = CrCl (mL/min)
  1. 1. Exclusion criteria will include any contra-indication to MRI, including permanent pacemaker, implantable metallic device/ prosthetic, aneurysm clip, non-removable piercing, or severe claustrophobia
  2. 2. Any medical condition that would compromise the imaging acquisition, in the opinion of the investigator
  3. 3. Individuals who have received systemic immune modifying therapy within 60 days of study enrollment (excluding HIV DNA vaccine).
  4. 4. Participants who are pregnant (female participants of childbearing age will be tested prior to injection of imaging agent at entry visit/initial visit - positive test will exclude from further participation in the study)
  5. 5. Participants who are breastfeeding
  6. 6. Female participants of reproductive potential (defined as women who have not been post-menopausal for at least 24 consecutive months (i.e., who have had menses within the preceding 24 months), or women who have not undergone surgical sterilization, specifically hysterectomy and/or bilateral oophorectomy or bilateral salpingectomy) must have a negative urine or serum pregnancy test with a sensitivity of at least 25 mIU/mL performed at the entry/initial visit, and again within 24 hours prior to PET imaging. Females of reproductive potential will need to be on 2 forms of birth control (excluding withdrawal or timing methods).
  7. 7. Participants who have had prior allogeneic stem cell or solid organ transplant
  8. 8. Screening absolute neutrophil count \<1,500 cells/mm3, platelet count \<100,000 cells/mm3, hemoglobin \< 8 mg/dL, estimated creatinine clearance \<60 mL/minute, aspartate aminotransferase \>2 x ULN, alanine aminotransferase \>2 x ULN.
  9. 9. Serious illness requiring hospitalization or parental antibiotics within the preceding 3 months
  10. 10. Current HIV-related opportunistic infection such as pneumocystis pneumonia, disseminated microbacterial infection, invasive cryptococcal disease, candidal esophagitis (limited oral thrush acceptable) and cerebral toxoplasmosis
  11. 11. Previously diagnosed myelodysplasia syndrome. or history of lymphoproliferative disease prior to study entry
  12. 12. History of congestive heart failure as defined by physician documentation in the medical record at any time prior to screening that required medication for heart failure or that required medical management within 1 year prior to study entry
  13. 13. Active Hepatitis C virus (HCV) infection. Prior history of treated HCV infection with sustained virological response will be allowed.
  14. 14. Active systemic autoimmune diseases.
  15. 15. Routine clinical vaccination within 14 days of study entry
