Clinical Trial of CNS-targeted HAART (CIT2)

21. mars 2014 oppdatert av: Ronald J Ellis, University of California, San Diego

HIV Neurocognitive Disorders: A Randomized Clinical Trial of CNS-Targeted HAART

CIT2 is a strategy for targeting HAART (Highly Active Antiretroviral Therapy) to the CNS (Central Nervous System) in patients with HIV associated neurocognitive impairment (HNCI).

The primary goal of this study is to evaluate the effectiveness of CNS-targeted (CNS-T) as compared to non-CNS-targeted (non-CNS-T) HAART in treating HNCI globally and in different domains of functioning known to be affected by HIV.

It is hypothesized that participants in the CNS-T arm will have greater improvement in neurocognitive functioning than those in the non-CNS-T arm.

The secondary goal of the study is to compare participants assigned to CNS-T and non-CNS-T HAART on measures of CNS and systemic HIV suppression (undetectable CSF and plasma VL).

It is also hypothesized that although CSF viral suppression will be more frequent in the CNS-T arm, plasma viral suppression will be similar in the two treatment arms.

Detaljert beskrivelse

"HIV Neurocognitive Disorders: A Randomized Clinical Trial of CNS-targeted HAART" is a randomized, controlled clinical trial to assess the efficacy of a strategy for targeting highly active antiretroviral therapy (HAART) to the CNS in patients with HIV associated neurocognitive impairment (HNCI). Contemporary cohort studies have consistently demonstrated that HNCI remains a prevalent disorder in patients receiving HAART. HNCI is a significant burden to persons living with HIV infection, caregivers, and the healthcare system. Thus the development of effective treatment strategies is of critical public health importance.

This study is based on findings from a previous study. Briefly, among individuals with HNCI who initiated a new antiretroviral (ARV) therapy regimen, those receiving more highly CNS-penetrating ARV regimens were more likely to successfully suppress cerebrospinal fluid (CSF) viral load (VL), and those who achieved CSF suppression (VL < 50 c/mL) had better neurocognitive (NC) outcomes. These findings suggest that NC outcomes of ART may be enhanced by the planned application of an ARV selection and clinical monitoring strategy designed to optimize the treatment of CNS infection. In the future it will become increasingly important to consider CNS penetration issues in selecting ART regimens. The randomized clinical trial proposed here would provide the level of evidence needed to formulate ART guidelines specific to HNCI.

Subjects eligible for this trial will be individuals with HNCI who anticipate initiation of a new ARV regimen or substitution of their existing regimen following contemporary treatment guidelines. A total of 120 patients at 3 study sites will be randomized 1:1 to receive a CNS-targeted (CNS-T) ARV strategy versus a non-CNS-targeted (Comparison) strategy. The primary outcome, change in global neuropsychological (NP) performance, will be assessed at 16 weeks. CNS-T will comprise two components: 1) initial selection of agents to optimize CNS penetration of the overall regimen; and 2) modification of the regimen if an interim pharmacokinetic (PK) assessment determines that plasma ARV exposure is not appropriate (overdosing, underdosing).

Beskrivelse

Exclusion Criteria:

  • Presence of serious illness, including HIV-related opportunistic infections, requiring systemic treatment and/or hospitalization until candidate either completes therapy or is clinically stable on therapy, in the opinion of the investigator, for at least 14 days prior to study entry.
  • Presence of neurologic disorders other than HIV judged to be the principal cause of neurocognitive impairment.
  • Presence of active, severe psychiatric disorders (e.g., major depression, schizophrenia) that would interfere with interpretation of the study evaluations or adherence to the study protocol or that might make their participation in the study problematic or unsafe.
  • Presence of active drug or alcohol use or dependence that, in the opinion of the investigator, would interfere with adherence to study requirements.
  • Use of any immunomodulator (interferons, interleukins, cyclosporine), vaccine, or investigational therapy including dexamethasone within 30 days prior to study entry.
  • Inability to provide informed consent.
  • Enrollment in other ARV treatment studies, unless the study is: 1) observational; 2) a compassionate use study that predated the current study; 3) one that does not require specific interventions (or one that does not dictate the regimen); or 4) one that does not include NP testing.
  • A positive serum or urine pregnancy test, if female and of reproductive potential.

Tidsramme
Neuropsychological Performance Change
Tidsramme: Baseline and 16 weeks
The outcome measure is change in performance from baseline to 16 weeks as measured by the global deficit score (GDS). The GDS is calculated by averaging the individual deficit scores from each neurocognitive test. Deficit scores for each test were calculated from age-, education-, gender-, and ethnicity-adjusted raw scores by methods that capture unexpectedly poor performance while ignoring better than expected performance. The GDS ranges in value from 0-5; higher scores indicate poorer cognitive functioning. Subjects with scores greater than or equal to 0.5 are considered cognitively impaired.
