About this study

Official title: An Open-Label, Randomized Controlled Trial of Pramipexole Versus Escitalopram to Treat Major Depressive Disorder (MDD) and Comorbid MDD With Mild Neurocognitive Disorder (MND) in Persons With HIV

A phase II, randomized, open-label, two-arm clinical trial evaluating the safety and efficacy of pramipexole extended release (ER) versus escitalopram for the treatment of major depressive disorder (MDD) and comorbid MDD with mild neurocognitive disorder (MND) in persons with HIV (PWH). Participants will be assessed comprehensively and briefly at intercurrent visits to monitor for toxicity, response to therapy, and to assess for dose changes.

An optional sub-study to evaluate treatment impact on the cerebrospinal fluid (CSF) profile will be conducted in a subset of 36 participants.

Arm 2: EscitalopramExperimentalNot described
Receives: Drug: Escitalopram

What is being measured

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

  1. Change in Beck Depression Inventory-II (BDI-II/BDI-2) total score defined as the sum of all symptom scores

    Measured: Baseline, Week 24

  2. Occurrence of Grade ≥3 Adverse Events (AEs) or Grade ≥2 neuropsychiatric AEs related to study treatment

    Measured: From study treatment administration through Week 24

  3. Occurrence of Grade ≥2 neuropsychiatric AEs related to study treatment

    Measured: From study treatment administration through Week 24

Secondary outcomes (8)
  1. Change in major depressive disorder (MDD) caseness, defined as the number of symptoms present from 0 to 9, of the symptoms of major depressive disorder

    Measured: Baseline, Week 24

  2. Complete remission of the major depressive episode defined as a score of 0 on all of the 9 symptoms

    Measured: Baseline, Week 24

  3. Change in neuropsychological (NP) z-score as assessed through 4 composite domain scores

    Each domain score is calculated as the average of the z-scores from the tests within the domain:

    • Outcome Domain 1: Cognitive Efficiency (Color Trails 1 and 2)
    • Outcome Domain 2: Verbal Learning and Memory (HVLT-R Learning Trials 1-3 Total and HVLT-R Delayed Recall)
    • Outcome Domain 3: Motor Skills (Grooved Pegboard, Non-dominant hand)
    • Outcome Domain 4: Language (Category Fluency Test [Animals])

    Measured: Baseline, Week 24

  4. Change in the medical outcomes study (MOS)-HIV mental health functioning summary score defined by the MOS-HIV Users Manual

    Measured: Baseline, Week 24

  5. Change in the MOS-HIV cognitive functioning subscale score defined by the MOS-HIV Users Manual

    Measured: Baseline, Week 24

  6. Occurrence of Grade ≥3 AEs or Grade ≥2 neuropsychiatric AEs (regardless of judged relationship to study treatment)

    Measured: From study treatment administration through Week 24

  7. Occurrence of Grade ≥2 neuropsychiatric AEs (regardless of judged relationship to study treatment)

    Measured: From study treatment administration through Week 24

  8. Number of participants with plasma HIV-1 RNA less than 50 copies/mL

    Measured: Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Pramipexole ER and Escitalopram in people with Major Depressive Disorder and Mild Neurocognitive Disorder, run by National Institute of Allergy and Infectious Diseases (NIAID) at 41 sites in 14 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 40 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: paused, as of the sponsor's last update on 14 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 41 sites in United States, Brazil, Kenya, Thailand, Botswana and 9 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Beck Depression Inventory-II (BDI-II/BDI-2) total score defined as the sum of all symptom scores (time frame: Baseline, Week 24). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06705478, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jul 2026.
