Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
* Documented HIV-1 infection
* Adults age 18-65 years
* On ART for a minimum of 18 months.
* CD4+ T cell count >500 at screening
* HIV-1 RNA plasma level of < 50 copies/mL by standard assays for at least 15 months (a single viral load measurement > 50 but < 500 copies/mL during this time period is allowable).
* Able to give informed consent
* Viral reservoir sensitivity to 3BNC117 and 10-1074. (Sensitivity of the viral reservoir to neutralization by 3BNC117 and 10-1074 will be tested following the screening visit (i.e. prior to randomization)).

Sensitivity of the viral reservoir to neutralization by 3BNC117 and 10-1074 will be tested following the screening visit (i.e. prior to enrollment and randomization). Isolated PBMCs will be analyzed using the PhenoSense HIV mAb Assay, Monogram Biosciences. The sensitivity of an individuals archieved proviruses to bNAb neutralization will be determined by the IC50 value of PBMC derived pseudovirus inhibition. Subjects that are considered sensitive to both 3BNC117 (IC90<=1.5 µg/mL) and 10-1074 (IC90<=2.0 µg/mL) AND MPI>97 AND fulfill the other inclusion/exclusion criteria will proceed to study enrolment and randomization.

If sensitivity cannot be determined by the PhenoSense HIVmAb Assay, participants will be screened for 3BNC117 and 10-1074 sensitivity using HIV env sequencing carried out in-house (Aarhus, Denmark). The method was originally established and validated by Rockefeller University that already has this method implemented. The method utilizes HIV-1 DNA envelope sequencing and a mathematical prediction binding algoritm of known binding sites of the antibodies. Based on the individual HIV env sequence, proviruses are categorized as "sensitive" or "resistant". Subjects that are determined to be sensitive to both 3BNC117 and 10-1074 (defined as at least 90% of known sequences sensitive to either bNAb) AND fulfill the other inclusion/exclusion criteria will proceed to study enrolment and randomization.

* Hepatitis B or C infection
* History of: Malignancy, excluding non-melanoma skin cancers, or organ transplantation
* Receipt of strong immunosuppressive or systemic chemotherapeutic agents within 28 days prior to study entry

* Pre-existing autoimmune or antibody-mediated diseases
* Women who are pregnant or breastfeeding, or unwilling/ unable to use an acceptable method of contraception (if of child bearing potential)
* Males or females who are unwilling or unable to use barrier contraception during sexual intercourse until plasma HIV-1 RNA is undetectable using standard assays
