About this study

Official title: A Randomized Trial of Tamoxifen Combined With Amphotericin B and Fluconazole for Cryptococcal Meningitis

The purpose of this study is to develop initial efficacy, feasibility, and safety data regarding the use of Tamoxifen in combination with amphotericin B and fluconazole in the treatment of cryptococcal meningitis. The results of the study will inform the design and feasibility of a larger study powered to a survival endpoint. The study hypothesis is that adding tamoxifen to standard antifungal therapy increases the rate of clearance of yeast from cerebrospinal fluid. Increased rates of clearance of yeast from cerebrospinal fluid have previously been associated with improved clinical outcomes, including survival and disability.

Read the detailed description

A randomized, open-label trial with 2 parallel arms: standard antifungal therapy versus tamoxifen augmented antifungal therapy during the first 2 weeks (induction phase) of treatment. The study will recruit in two sites in Ho Chi Minh City: the Hospital for Tropical Diseases (HTD), and Cho Ray Hospital (CRH). 25 patients will be enrolled into the two study arms (intervention versus control). All anti-fungal administration will be directly observed by ward staff.

Intervention arm: Induction phase treatment (days 1-14): Tamoxifen will be given orally in a dose of 300mg/day for the first 14 days following randomization. It will be administered by nasogastric tube where patients are unconscious. In addition patients will receive amphotericin 1mg/kg once daily iv and fluconazole 800mg once daily orally. The tamoxifen will be administered in the morning combined with amphotericin and fluconazole dose.

Control arm: Induction phase treatment (days 1-14): Patients will receive amphotericin 1mg/kg/day combined with fluconazole 800mg once daily for the first 2 weeks. Amphotericin and fluconazole will be administered simultaneously.

The primary efficacy endpoint will be the rate of clearance of yeast cells from cerebrospinal fluid (CSF) over the first 2 weeks following randomisation. Patients will be followed for 10 weeks, which is conventional in clinical trials in cryptococcal meningitis. After the first 2 weeks of study treatment, all patients will receive fluconazole 800mg/day for 8 further weeks, until the study end. At this point, HIV infected patients will be switched to long term secondary prophylaxis with fluconazole 200mg/day as per standard practice. For HIV uninfected patients, the decision to continue antifungal treatment, and at which dose, will be made on a case by case basis by the attending physician in consultation with the patient.

What is being measured

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

  1. Early Fungicidal Activity (EFA), i.e. the rate of clearance of yeast from cerebrospinal fluid

    In the trial, lumbar punctures are scheduled on days 1, 3, 7, 14, and additionally as clinically indicated. Whenever a lumbar puncture is performed, the study team will determine the amount of viable yeast in CSF through culture. Based on the patients' longitudinal quantitative yeast count measurements, EFA will be determined as previously described e.g. see N Engl J Med 2016; 374:542-54

    Measured: over the first 2 weeks following randomisation

Secondary outcomes (11)
  1. Survival until 10 weeks after randomization

    International treatment guidelines recommend 10 weeks of high dose antifungal therapy for cryptococcal meningitis - an initial phase of amphotericin based induction therapy for 2 weeks followed by 8 weeks of moderate to high dose fluconazole. The rate of survival until this 10 week period of therapy is completed is a frequent endpoint in trials of treatment for cryptococcal meningitis.

    Measured: 10 weeks after randomisation

  2. Disability at 10 weeks

    Disability is an expected consequence of cryptococcal meningitis, including blindness, deafness and other focal neurological deficits. Neurological disability will be assessed using the modified Rankin score and the Two Simple Questions, and the results of each test combined and classified as good, intermediate, severe disability, or death, as we have previously published.

    Measured: at 10 weeks

  3. Adverse events

    The proportion of patients with any grade 3 or 4 adverse event, serious adverse event, or unexpected serious adverse event will be compared between treatment groups.

    Measured: During hospital stay, an average of 10 weeks

  4. Rate of IRIS until 10 weeks (in HIV infected patients only)

    The investigators will model the rate of IRIS over time with a cause-specific hazards model taking into account the competing risk of prior death.

    Measured: until 10 weeks

  5. Rate of Cryptococcal meningitis relapse

    A pragmatic definition of relapse will be used. This is defined as either intensification of antifungal therapy above that according to the study antifungal schedule, or readmission for treatment of cryptococcal disease.

    Measured: until 10 weeks

  6. QT prolongation

    Prolongation of the QT interval is a potential side-effect of both Tamoxifen and fluconazole, although it is not clear that either drug increases the risk of Torsade de Pointes, a potentially life-threatening arrhythmia. The QT interval will be estimated manually from 3 chest and 3 limb leads from a high resolution (50mm/sec) 12-lead ECG. The median value will be determined and used to calculate the corrected QT interval (QTc) using using Framingham's formula

    Measured: During hospital stay, an average of 10 weeks

  7. Visual deficit at 10 weeks

    Visual deficit occurs in 5-40% of patients with cryptococcal meningitis depending upon underlying immune status. The pathogenesis is unclear. The study team will compare the incidence of blindness and other visual deficit between treatment groups. Visual deficit will be assessed using a simple 6 point scale.

    Measured: at 10 weeks

  8. Time to new neurological event or death until 10 weeks

    A neurological event is defined as a fall in Glasgow coma score by ≥2 points for ≥2 days from the highest previously recorded Glasgow coma score (including baseline) or the occurrence of any of the following adverse events: cerebellar symptoms, coma, hemiplegia, paraplegia, seizures, cerebral herniation, new onset blindness or deafness, or cranial nerve palsy.

    Measured: until 10 weeks

  9. Longitudinal measurements of intracranial pressure during the first 2 weeks

    Intracranial pressure (ICP) will be measured at study entry, day 3, 7, and 14, and at other times as clinically indicated. The decline in raised intracranial pressure over the first 2 weeks will be modelled and compared between treatment arms.

    Measured: during the first 2 weeks

  10. CD4 count at 10 weeks

    CD4 count measurement is indicated in HIV infected patients, and CD4 lymphopenia has been described in HIV uninfected patients with cryptococcal meningitis. Moreover, Tamoxifen may reduce CD4 cell apoptosis which may be beneficial.

    Measured: at 10 weeks

  11. Blood and CSF concentrations of amphotericin, Tamoxifen and fluconazole

    All patients will undergo pharmacokinetic sampling to enable the description of the concentrations of Tamoxifen and fluconazole in plasma and CSF, and of amphotericin in blood, and relate these to the rate of clearance of yeast from CSF.

    Measured: During hospital stay, an average of 10 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tamoxifen, Amphotericin B and Fluconazole in people with Meningitis Streptococcal and Hiv, run by Oxford University Clinical Research Unit, Vietnam at 3 sites in Vietnam.

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 7 inclusion and 13 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: finished, as of the sponsor's last update on 2 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Vietnam. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Early Fungicidal Activity (EFA), i.e. the rate of clearance of yeast from cerebrospinal fluid (time frame: over the first 2 weeks following randomisation). 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 NCT03112031, which also lists 57 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 2 Dec 2019.
