To study the pharmacokinetic profile of micafungin administered, at a dose of 8 mg/Kg/day, to neonates suffering from definite or suspected systemic Candidiasis. |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate the proportion of success and of failure of the therapy with micafungin among treated neonates
• To identify a conversion factor to relate plasma levels of micafungin into capillary and venous blood, measured through blood samples from the heel and from a peripheral vein, collected simultaneously
• To evaluate the safety of Micafungin in neonates
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Infection by systemic Candidiasis, definite or suspected.
a) Definite systemic Candidiasis is diagnosed in case of isolation of Candida from at least one sample collected from a normally sterile site (Blood, CSF, Urine, Peritoneal Fluid) and/or positivity to Candida through PCR (Septifast test), associated with at least one clinical symptom (fever or hypothermia, mottled skin, feeding difficulties, muscular hypotonia or hypertonia, apnoea crisis, bradycardia, tachycardia, hypotension, dyspnea, polypnea, desaturation) and one laboratory symptom (WBC ≤5000/mm3 or WBC ≥20.000/mm3, I/T ratio >2, Platelet count ≤100.000/mm3, C-reactive Protein >0,5 mg/dL, Standard Base Excess >-7 mmol/L, CSF pleocytosis-cells ≥ 6).
b) Suspected systemic Candidiasis is diagnosed in case of worsening of clinical conditions while on therapy with antibiotics, isolation of Candida from at least two non contiguous sites (tracheal aspirate, gastric aspirate, faeces) associated with at least one clinical symptom (fever or hypothermia, mottled skin, feeding difficulties, muscular hypotonia or hypertonia, apnoea crisis, bradycardia, tachycardia, hypotension, dyspnea, polypnea, desaturation) and one laboratory symptom (WBC ≤5000/mm3 or WBC ≥20.000/mm3, I/T ratio >2, Platelet count ≤100.000/mm3, C-reactive Protein >0,5 mg/dL, Standard Base Excess >-7 mmol/L, CSF pleocytosis-cells ≥ 6) and positivity to test ELISA for the mannan antigen (≥250 pg/ml).
2. Neonates affected by definite or suspected Candida meningitis and/or hydrocephalus due to Candida infection and/or bearing external ventricular derivation, until enrolment of 4 subjects with this characteristics.
3. Parents of neonates, or their legal representative, able to consent and comply with protocol requirements.
4. Survival expectation not inferior to 3 days. |
|
E.4 | Principal exclusion criteria |
1. Hepatic acute or chronic insufficiency with at least one of the following abnormal parameters:
a. Ammonium > 85 µg/dL
b. ALT/GPT > 40 UI/L
c. AST/GOT > 40 UI/L
d. Direct Bilirubin > 2mg/dL
2. Baseline INR >5%
3. Known allergy or hypersensitivity to echinocandins or any of the excipients present in the formulation of the IMP.
4. Micafungin infusion already started.
5. Neonates affected by definite or suspected Candida meningitis and/or hydrocephalus due to Candida infection and/or bearing external ventricular derivation, if already 4 subjects with this characteristics have been enrolled into the study. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
• Quantification of micafungin levels into blood, through samples collected with capillary micro-method (draws from the heel). Blood draws are to be taken before infusion with the IMP and after 1, 2 and 8 hours from the end of the intravenous infusion, in one of the treatment days starting from the third and within the tenth.
• Quantification of micafungin levels in the cerebrospinal fluid, through samples collected from 4 neonates with Candida meningitis, hydrocephalus due to Candida infection and/or with external ventricular derivation. CSF draws are to be taken before infusion with the IMP and after 1, 2 and 8 hours from the end of the intravenous infusion, in one of the treatment days starting from the third and within the tenth. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Between third and tenth day of therapy. |
|
E.5.2 | Secondary end point(s) |
1) To evaluate the percentage of success and failure of therapy with micafungin, among treated patients, on the basis of the following definitions:
- In case of definite or suspected sepsis, the success of the therapy will be determined by survival associated with the negative results to Candida test of two consecutive blood cultures, performed starting from the beginning of treatment, or, only in case of suspected sepsis, determined by resolution of clinical and laboratory symptoms together with reduction of mannan antigen blood level (<250 pg/ml).
- In case of definite or suspected sepsis, the failure of the therapy will be determined by death due to Candida sepsis, by confirmation of persistence of positive result to Candida test at 14th (± 2days) day from one blood culture performed in the previous days, by the need to add or switch to another antifungal agent and/or change of micafungin dosage for the resolution of infection at any time or, only in case of suspected sepsis, by the persistence of Candida colonization in the different indicated sites associated with the persistence of clinical and laboratory symptoms and with high blood level of the mannan antigen (≥250 pg/ml) at 14th day (± 2days) from the start of the therapy.
- In case of Candida meningitis, the success of the therapy will be determined by survival associated with the negative results to Candida test of at least three consecutive CSF cultures, performed starting from the beginning of treatment, and resolution of clinical and laboratory symptoms.
- In case of Candida meningitis, the failure of the therapy will be determined by death due to Candida meningitis, by persistence of Candida infection as resulted from confirmation of positive CSF culture after the 14th day of therapy (± 2days) or by the need to add or switch to another antifungal agent or dosage change of micafungin for the resolution of Candida infection at any time.
- In case of neonates with hydrocephalus due to Candida infection and/or external ventricular derivation, the success of the therapy will be determined by survival associated with the negative results to Candida test of at least three consecutive CSF cultures, performed starting from the beginning of treatment.
- In case of neonates with hydrocephalus due to Candida infection and/or external ventricular derivation, the failure of the therapy will be determined by death due to Candida infection, by need o add or switch to another antifungal agent or dosage change of micafungin for the resolution of Candida infection at any time or by the persistence of Candida infection as resulted from confirmation of positive CSF culture after from the 14th day of therapy (± 2days).
2) For the pharmacokinetic assessment, in a sub-set of five neonates, blood draws will be collected simultaneously either via capillary micro-method (withdraw from the heel) and venous (withdraw from a peripheral vein) in order to compare the methods and identify a conversion factor between the levels of drug in capillary and venous blood, through simultaneous withdrawals.
3) Evaluation of adverse events (serious and non serious) and adverse drug reactions throughout the duration of trial by assessment of physical examination, vital signs, 12-lead electrocardiogram. Serious and non serious adverse events will be collected from Day1 until 30 days after trial participation, where possible. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
1) 14 days to 21days
2) Between third and tenth day of therapy.
3) Throughout the treatment period of approximately 21 days. |
