About this study

Official title: Advanced Neuroimaging Evaluation of the Central Nervous System Biological Changes Associated With Efavirenz Therapy Switch to an Raltegravir-based Regimen

In this study investigators will use a multi-modal imaging approach of MRS and fMRI to comprehensively assess the biological changes in the brain associated with EFV-based regimen (EFV/FTC/TDF), specifically alterations in the brain circuitry, function and local neurochemistry, and their correlation with neuropsychological function.

Read the detailed description

In a cohort of HIV-infected patients who are clinically stable on the commonly use regimen of EFV/emtricitabine (FTC)/truvada (TDF) or Atripla, investigators propose to replace the EFV component with an integrase inhibitor, Raltegravir (RAL), given as the RAL and FTC/TDF to evaluate the EFV-related neural alterations. This is a multidisciplinary study which will be lead by Dr. Nina Lin, in collaboration with the research teams of Dr. Alexander Lin, Director of the Center for Clinical Spectroscopy, and Dr. Emily Stern, Director of the Functional Neuroimaging Laboratory, both members of the Brigham and Women's Department of Radiology at Harvard Medical School, as well as Dr. Jane Epstein, a researcher in Dr. Stern's research group. Dr. Epstein is a staff psychiatrist at Brigham and Women's hospital with extensive experience and expertise in research on abnormalities of affective and motivational processing in the context of neuropsychiatric disorders. Investigators will utilize the established clinical research platform in the Infectious Disease outpatient clinical practice at the Brigham and Women's Hospital, where there is currently have many ongoing HIV-related studies and a large panel of HIV-infected patients motivated to be involved in clinically relevant research. Investigators propose to use advanced neuroimaging to measure biologically changes in the brain associated with long-term EFV use with the following specific aims:

  1. Determine changes in neurometabolites measured by MRS in the brain associated with long-term EFV use
  2. Assess for alterations in neural activity correlated with affective symptoms associated with EFV vs RAL use using fMRI, and their associations with changes in neurometabolites assessed by MRS, and with changes in cognition assessed by Trail Making and Digit Substitution Tests.
  3. Determine changes in emotion, cognition and sleep quality after switching from EFV to RAL, and how they correlate with subject treatment preference.

This clinical study will extend our current understanding of EFV neurotoxicity by further defining the nature of these biological changes. Further elucidation of the neurobiological underpinnings of EFV-induced CNS toxicity will have clinical relevance in improving the quality of life and drug adherence of HIV-infected patients on ART, especially among older patients or those with baseline neuropsychiatric disorders, whom at baseline are more vulnerable to neurocognitive decline from long-term HIV infection.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Neurometabolites Based on Magnetic Resonance Spectroscopy (MRS)

    Assess the levels of neuro-metabolites measured by MRS at week 0 before switching to the efavirenz-based therapy. Two areas of the brain: 1) posterior cingulate gyrus and 2) anterior cingulate will be assessed for the levels of brain creatine (Cr), gamma-aminobutyric acid (GABA) and glutathione (GLU).

    Measured: week 0 and week 8

  2. Neural Activation Networks Using Functional Magnetic Resonance Imaging (fMRI)

    Assess changes in neural activation correlated with affective disturbances associated with EFV vs. RAL using fMRI employing a paradigm that probes affective symptomatologies typical with EFV use; anxiety/dysphoria and affective dysregulation, and their association with changes in cognitive function. Four brain regions of interests (ROIs) are specified to show the differential frontal-limbic activation patterns in the task-evoked neural responses to the 3 linear contrasts of Pre-/Post-/ Pre-vs. Post-switch: [Negative Word vs. Neutral Word] x [No-Go Trial Block vs. Go Trial Block]: anterior Frontal Pole (aFP), posterior Cingulate Gyrus (pCG), dorsal anterior Cingulate Gyrus (daCG), Left Hippocampus (LHC). A linear mixed-effects model is utilized to examine the effect sizes of the key Regimen/Condition contrasts, with the Subject factor as the random-effect, and Age incorporated as a co-variate of no interest. A z-score is the Mean with a SD=1 and Measure of Dispersion equal to 1.

    Measured: week 0 and week 8

Secondary outcomes (7)
  1. Other Neurometabolite Changes Measured by MRS

    Use MRS to evaluate a fuller panel of known neurometabolites (in addition to the primary endpoints) to evaluate for prominent and significant changes associated with EFV use.

    Measured: week 0 and week 8

  2. Neurocognitive Changes Measured by a Panel of Indexes: WAIS-R, HAMD, DASS-21, FRSBE, STAI

    Assess for changes in cognitive and affective function prior to and after switching off EFV-based regimen. Indexes used to access neurocognitive changes included:

    1. Wechsler Adult Intelligence Scale (WAIS-R) Digital Symbol Substitution Test: sensitive to brain dmamage, dementia, age and depressive changes. Range of 0-100, the higher the score the better the person's performance
    2. Hamilton Rating Scale for Depression (HAMD): Measure of depression. Score of 0-7 is normal, score of >20 is moderate/severe depression
    3. Depression Anxiety Stress Scale (DASS-21) the lower the score, the less severe depression, anxiety and stress. Scale range of 0-63
    4. Frontal Systems Behavior Scale (FRSBE): Increased score indicates greater behavioral impairment associated with frontal systems, range 37.2 to 186
    5. Spielberger state trait anxiety inventory (STAI): the higher the score the greater then anxiety level, range of 20 to 80.

    Measured: week 0 and week 8

  3. Fasting Lipid Profile

    Measure the change in fasting lipid panel prior to and after switching off EFV-based regimen.

    Measured: week 0 and week 8

  4. Sleep Quality

    Assess for changes in sleep pattern and quality prior to and after switching off EFV-based regimen through a self-administered Pittsburg Sleep Quality Index (PSQI). Measure consists of 19 items with each weighted on 0-3 scale and the sum produces a total score, which ranges from 0-21. The lower the score the healthier the sleep quality.

    Measured: week 0 and week 8

  5. ART Regimen Preference

    Evaluate patient preference in ART regimen (Atripla, EFV/FTC/TDF versus RAL + FTC/TDF) through self-administered questionnaires.

    Measured: week 0 and week 8

  6. Markers of Immune Activation

    Change in markers of immune activation and inflammation associated with change to RAL (ie, sCD14, IL-6, hsCRP, D-dimer, CRP, LPS, sCD163, EndoCab)

    Measured: week 0 and week 8

  7. Change in Level of EFV and Metabolites

    Correlate change in level of EFV and metabolites with neurocognitive and neuroimaging changes

    Measured: week 0 and week 8
