简要总结
Study objectives To evaluate the safety of the echinocandin anidulafungin for prophylaxis or treatment of invasive fungal infections (IFI) in hematologic patients.
Study design, Study conduct period Prospective, open label, phase II, one arm, single centre study October 2009 - September 2010
Study population Twenty adult patients (≥ 18 years) with a hematologic disorder and an indication for antifungal prophylaxis or therapy, but a relative contraindication for azoles or polyenes due to hepatic and renal dysfunction respectively
Methods and Main Out-come Variables Main Outcome Parameter Safety: Adverse events and changes of important laboratory parameters with clinical impact will be reported.
Secondary Outcome Parameter Efficacy: In therapeutically use the outcome will be categorized into success or failure. For patients receiving anidulafungin as prophylaxis the number and rate of breakthrough infections will be documented.
Risk assessment Treatment related adverse effects as reported in the approved physician prescribing information (usually mild and with an incidence of < 5%). Treatment failure due to resistant pathogens.
Expected benefit from this study IFI is a major cause of death among hematological patients, especially those undergoing high dose chemotherapy. It is conceivable that anidulafungin is a new treatment option for patients in whom azoles or polyenes are relatively contraindicated.
详细描述
Treatment of patients with hematologic disorders is frequently complicated by invasive fungal infections (IFI). The current spectrum of pathogens in this patient population is characterised by an increasing rate of aspergillosis, atypical moulds and yeasts, which might be explained by an extended application of myelosuppressive chemotherapy and prophylactic use of antibiotic therapy, but also more sensitive diagnostic tools. Although several new antifungal drugs have been approved recently for the treatment of invasive fungal infections, the mortality rates remain unacceptably high. In patients with suspected IFI invasive diagnostic procedures can often not be performed due to thrombocytopenia and blood testing of fungal antigens with ELISA or PCR-methods are at most additive tools at this time. Thus, antifungal drugs are frequently applied empirically when neutropenic fever persists despite of antibiotic therapy or preemptive in case of radiological or laboratory suspicion of IFI. The antifungal armamentarium consists mainly of azoles, polyenes, and echinocandins. Therapy with azoles is frequently complicated by hepatological side effects and drug interactions, whereas the application of polyenes is often associated with a worsening of the renal function, severe hypopotassemia and shivering. Because of their favourable efficacy and outstanding safety profile, nowadays echinocandins are increasingly used in hematologic wards, especially in patients with renal or liver comorbidity. Anidulafungin is a novel echinocandin with potent invitro fungicidal activity against several pathogen yeasts and moulds like Candida- or Aspergillus spp. It has recently been approved by the EMEA for treatment of invasive candidiasis in non-neutropenic patients. A low cytochrome P450 interaction profile has been reported and dose adaption in case of hepatical or renal impairment is not recommended. In the pivotal clinical trial anidulafungin achieved a superior response rate for treatment of invasive candida infection in comparison with fluconazole. In this trial, only a quarter of patients had cancer and only 3% had neutrophil counts below 500/cm3 blood at randomisation. Although the clinical experience of the efficacy and tolerability of anidulafungin in adult hematologic patients is limited, the Infectious Diseases Society of America recently recommended anidulafungin for use in neutropenic patients with candidiasis.
Primary endpoint:
Safety: For all patients who will receive anidulafungin without regard to indication the incidence of (serious) adverse events and changes of important laboratory parameters (in particular liver and renal function parameters) with clinical impact will be reported.

入选标准
- •Adult patients (≥ 18 years) with a hematologic disorder AND an indication for IFI prophylaxis or therapy, but a relative contraindication for azoles or polyenes due to hepatic or renal dysfunction*, are scheduled to receive anidulafungin for one of the following specific indications:
- •Need for primary antifungal prophylaxis in patients with Acute leucaemia/MDS during induction, reinduction or consolidation chemotherapy (who are expected to become neutropenic for at least 10 days) OR after allogenic HSCT with GvHD (at least grade II or more - systemic steroid treatment required)
- •Need for secondary antifungal prophylaxis in patients with the history of a proven or probable invasive fungal infection who are expected to become neutropenic during induction, reinduction or consolidation chemotherapy
- •Indication for treatment of proven**, probable or possible fungal infection:
- •Neutropenic patients with fever resistant to antibiotics (empirical use)
- •Neutropenic patients with fever resistant to antibiotics and additive laboratory or imaging signs of IFI (preemptive use)
- •Patients who failed other antifungal therapy due to intolerance or progressive infection
排除标准
- •Absence of written informed consent
- •Female patients who are pregnant or lactating
- •Use of anidulafungin within 30 days prior to study
- •Known hypersensitivity to anidulafungin
- •Proven IFI with pathogen of known resistance to echinocandins (e.g. zygomycetes)
- •Life expectancy less than 1 month
- •Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.
