Clinical Trial Summary

The trial evaluates the overall tolerability of the drug and the efficacy of aerosolised amphotericin B as a lipid complex (ABLC) for primary prophylaxis of invasive pulmonary aspergillosis (IPA) in pediatric patients with acute leukemia undergoing intensive chemotherapy.

Description:

In recent years the incidence of invasive fungal infection (IFI) especially when caused by filamentous fungi has increased in patients with haematological malignancies and there exists an international consensus on diagnostic criteria. Despite diagnostic and therapeutic progress, invasive aspergillosis remains a major clinical problem of haematological patients, given the still high mortality rates and the huge economic cost of hospitalization of patients, which is attributable to aspergillosis. In addition to the morbidity and mortality rates, these infections interfere with the chemotherapy treatment plan with the risk of compromising the outcome of the antileukemic treatment.

In a few uncontrolled studies inhaled amphotericin B deoxycholate showed some benefit in haematological patients, however it was not effective in a large multicenter study with neutropenic patients. Based on the outcome of that clinical trial, the use of aerosolised amphotericin B deoxycholate in neutropenic patients was abandoned for nearly a decade. During this time the use of azole agents as drugs of choice for antifungal prophylaxis in high risk patients was consolidated. However, one of the main problems in the use of triazoles with activity against filamentous fungi (itraconazole, voriconazole, posaconazole) is drug-drug interactions due to their CYP3A4 inhibitory activity. One of the most serious interactions is that which occurs with vincristine, used throughout the treatment of acute lymphoblastic leukemia, and which has lead to reports of neurotoxicity due to metabolic inhibition.

ABLC (Abelcet®) belongs to the group of polyenes with antifungal activity against a broad spectrum of fungal species, including Aspergillus spp. The active component of ABELCET®, amphotericin B, acts by binding to sterols in the cell membrane of susceptible fungi, with a resultant change in the permeability of the membrane. Mammalian cell membranes also contain sterols, and damage to human cells is believed to occur through the same mechanism of action.

Abelcet® is recommended for the intravenous treatment of a broad spectrum of systemic fungal infections in adult patients. Although it has a pediatric indication, there are numerous studies published regarding the safety levels of Abelcet® administered intravenously in children and in haematological adults patients which look very promising. In this context, the working hypothesis proposed in this project is that the administration of aerosolised ABLC for pediatric patients with acute leukemia treated with intensive chemotherapy will be an effective alternative as a prophylaxis of pulmonary fungal infections in these patients.

In the treatment of pediatric patients with haematological malignancies the use of intensive chemotherapy is required, which is immunosuppressive and therefore significantly increases the risk of IFI, especially filamentous fungi. IPA is associated with high mortality (>50%) in those patients, making it imperative to adopt effective, preventive, prophylactic measures. Drug interactions occur frequently with triazole antifungal drugs; cases of clinically significant interactions with vincristine, an anchor drug in the treatment of the majority of pediatric leukemia, are documented. On the other hand, there are promising data from previous studies regarding the safety and efficacy of the intravenous ABLC formulation (Abelcet®) in the treatment of pediatric patients with fungal infections.

If the working hypothesis is confirmed, the aerosolised ABLC treatment would be an effective, safe and reliable prophylactic option for IPA. It would offer an alternative to the systemic administration of antifungal triazoles without affecting the antileukemic treatment in pediatric patients with AL.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Adverse Events That Results in the Interruption of Treatment, as a Measure of Safety and Tolerability	is assessed by the proportion of patients who discontinue prophylactic treatment with Abelcet® due to an adverse event that is related or not to the study drug or for intolerability to it. The last week of treatment will have a different calendar for each participant, depending on the number of cicles needed by each patient (it has been anticipated up to 5 cicles of 2-6 weeks each).	at the Baseline visit (week 1) and during the Last week of treatment, up to 6 weeks
Secondary	Efficacy of Primary Prophylaxis With Nebulized Abelcet® on the Incidence of Invasive Pulmonary Aspergillosis	The incidence of invasive pulmonary aspergillosis during the Abelcet® prophylactic treatment period was assessed by the relation between the number of patients with invasive pulmonary aspergillosis and the number of paediatric patients on prophylaxis with Acute Leukaemia (AL) undergoing intensive chemotherapy.	at the Baseline visit (week 1) and at the end of the profilaxis treatment phase, up to 6 weeks
Secondary	Invasive Pulmonary Aspergillosis -Related Mortality During Primary Prophylaxis With Abelcet®.	Percentage of deaths related to Invasive Pulmonary Aspergillosis during the prophylactic treatment period with Abelcet® in paediatric patients with Acute Leukaemia undergoing intensive chemotherapy.	at the Baseline visit (week 1) and at the end of the profilaxis treatment phase, up to 6 weeks
