Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 2 years and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Age greater than 2 years.
  • Proven or probable invasive mucormycosis, as defined by modification of consensus European Organization for Research and Treatment of Cancer (EORTC)/Mycosis Study Group (MSG) criteria. In brief, proven mucormycosis is defined as: 1) histopathologic or cytopathologic examination showing broad-based, aseptate, ribbon-like hyphae consistent with Mucorales from needle aspiration or biopsy specimen, with evidence of associated tissue damage (either microscopically or unequivocally by imaging); OR 2) a positive culture result for a sample obtained by sterile procedure from normally sterile and clinically or radiologically abnormal site consistent with infection, excluding urine and mucous membranes. Probable mucormycosis is defined as: 1) an at-risk host; AND 2) positive culture, cytology, or polymerase chain reaction (PCR) test (run at a CLIA-certified clinical microbiology laboratory) from sputum, bronchoalveolar lavage (BAL), endoscopy/colonoscopy, or sinus aspirate/biopsy; AND 3) 1 major or 2 minor clinical criteria.
  • Radiographic study by Computerized Tomography (CT) or Magnetic Resonance Imaging (MRI) has been obtained within 4 calendar days prior to enrollment and shows evidence of infection (i.e. focal nodule, mass, or abscess, or enhancement, or evidence of tissue edema or destruction that is not attributed to post-surgical reaction).
  • Subject or authorized decision maker able to provide informed consent.

Who cannot join

  • High likelihood of death within the 48 h after enrollment (investigator's discretion).
  • High likelihood of death due to factors unrelated to mucormycosis (e.g. due to uncontrolled and/or relapsed malignancy, severe graft versus host disease, other underlying diseases, etc.) within 30 days following enrollment (investigator's discretion).
  • Patient unable to receive enteral medication (oral or via feeding tube).
  • Infection limited to the supra-fascial skin (skin lesions in the presence of disseminated disease, deep invasive tissue infection spreading from a primary skin site, or subcutaneous infections extending to fascia are allowed).
  • Patient has received > 14 days of polyene antifungal therapy (i.e. amphotericin B deoxycholate, liposomal amphotericin B, amphotericin B lipid complex, or amphotericin B colloidal dispersion) at the time of screening.
  • Patient is already taking deferasirox therapy for any reason at the time of screening.
Show all 11Show fewer
  • Patient is allergic to or intolerant of deferasirox or LAmB.
  • Patient has significant renal dysfunction at the time of screening, defined as serum creatinine of > 3 mg/dL or a calculated creatinine clearance of < 30 ml/min (by the Cockroft-Gault formula: (140 - age (yrs) * wt (kg)) * 0.85 (for females) / (72 * serum creatinine (mg/dL)).
  • Patient has significant hepatic dysfunction at the time of screening, defined as BOTH an AST or ALT > 10 times the upper limit of normal, AND a direct (not total) bilirubin > 5 times the upper limit of normal.
  • Women of child-bearing potential (those with menses within the last year) with a positive serum pregnancy test.
  • Enrollment refused by the primary physician.

About this study

The purpose of this study is to determine if the addition of the medication, deferasirox, to standard antifungal therapy for the infection, mucormycosis, is safe and effective

Read the detailed description

Because of its extremely high morbidity and mortality, it is imperative to look for new antifungal therapies to treat mucormycosis. The agents of mucormycosis are exquisitely sensitive to iron availability, and we and others have demonstrated that iron chelation therapy improves the survival of rodents with mucormycosis. Deferasirox (Exjade) is the first orally bioavailable iron chelator approved for use in the United States (US) by the Food and Drug Administration (FDA), with an indication for treatment of iron overload from chronic transfusions. In clinical studies, deferasirox has been well tolerated and effective in iron-overloaded patients.

Although the safety and efficacy of deferasirox have been extensively evaluated in iron-overloaded patients, there are minimal data in non-iron-overloaded patients or in infected patients. Therefore, the safety and efficacy of deferasirox in patients with mucormycosis is unclear, and confirming safety in the current study, at the currently planned dose, is required to lay the groundwork for a future phase III clinical trial.

This is a prospective, phase II, randomized, double-blinded, placebo-controlled study of liposomal amphotericin B (LAmB; AmBisome) plus deferasirox vs. LAmB plus placebo for mucormycosis infection. Twenty patients with proven or probable mucormycosis (except for isolated skin infection) by consensus EORTC/MSG criteria, who have received less than 14 days of antifungal therapy for mucormycosis, and who have had radiographic imaging by CT or MRI within the past 72 hours that shows evidence of infection, will be randomized to receive LAmB plus deferasirox or placebo (n = 10 per arm), with randomization stratified by study site.

The primary objective is to determine the safety and tolerability of adjunctive deferasirox therapy in patients being treated with LAmB for mucormycosis, and to obtain exploratory data on the efficacy of the iron chelation treatment. The exploratory efficacy endpoint will be the global response rate (composite of clinical and radiographic response) at end of study drug administration, as determined by a blinded adjudication committee.

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 4 inclusion and 11 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 16 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States. 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 6 Oct 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Safety and Tolerability of Adjunctive Deferasirox Therapy in Patients Being Treated With LAmB for Mucormycosis (time frame: 14 days). 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 NCT00419770, which also lists 5 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 16 Oct 2023.
