E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Pharmacogenetics Version: 1.0 Date: 31/03/2020 Title: Translational Research Objectives: 1) To assess the incidence of commonly mutated genes with prognostic relevance (e.g. NPM1, FLT3) in the study population. 2) To assess Minimal Residual Disease after experimental treatment by multicolour flow cytometry and molecular analysis (if molecular marker available). 3) To perform a wide genomic analysis on BPDCN-like AMLs samples to identify recurrent genetic mutations and aberrant pathways in order to better characterize this rare biological entity. The use of BPDCN-like signature coupled with molecular evaluation may allow for a better selection of patients who may benefit from anti CD123 novel targeted therapy.

Farmacogenetica Versione: 1.0 Data: 31/03/2020 Titolo: Ricerca Traslazionale Obiettivi: 1) Per valutare l'incidenza di geni comunemente mutati con rilevanza prognostica (ad esempio NPM1, FLT3) nella popolazione in studio. 2) Valutare la Malattia Residua Minima dopo il trattamento sperimentale con citometria a flusso multicolore e analisi molecolare (se disponibile marcatore molecolare). 3) Eseguire un'ampia analisi genomica su campioni di AML simili a BPDCN per identificare la genetica ricorrente mutazioni e percorsi aberranti al fine di caratterizzare meglio questa rara entità biologica.L'uso di una firma simile a BPDCN unita a una valutazione molecolare può consentire una migliore selezione dei pazienti che possono beneficiare della nuova terapia mirata anti-CD123.

1. Diagnosi di leucemia promielocitica acuta (APL, FAB sottotipo M3). 2. Il paziente presenta persistenti tossicità clinicamente significative di Grado = 2 in seguito a precedente chemioterapia (escluse alopecia, nausea, fatica e valori di funzionalità epatica [come richiesto nei criteri di inclusione]). 3.

Il paziente ha ricevuto un trattamento con farmaco sperimentale nei 14 giorni precedenti l’ingresso nello studio. 5. Il paziente è stato precedentemente trattato con tagraxofusp. 6. Il paziente ha una neoplasia attiva e/o una storia tumorale (escluso MDS antecedente) che può portare a valutazioni erronee degli end-points dello studio. I pazienti con una storia tumorale (nei 2 anni precedenti l'ingresso) con un sostanziale potenziale di recidiva e/o neoplasie attive in corso saranno valutati caso per caso. I pazienti con le seguenti diagnosi neoplastiche sono eleggibili: carcinoma cutaneo non melanoma, carcinoma in situ, neoplasia intraepiteliale cervicale, carcinoma prostatico organo-confinato senza evidenza di malattia progressiva. 7.

Il paziente ha una patologia polmonare incontrollata e clinicamente significativa (come broncopneumopatia cronica ostruttiva, ipertensione polmonare) che, secondo il parere dello Sperimentatore, potrebbe mettere il paziente ad un rischio significativo di complicanze polmonari durante lo studio. 9. Il paziente ha una leucemia attiva o sospetta del sistema nervoso centrale (SNC). Se sospetta, la leucemia SNC dovrebbe essere esclusa con imaging e/o esame del liquido cerebrospinale. 10.

Il paziente ha una patologia incontrollata intercorrente tra cui, ad esempio, un’infezione incontrollata, una coagulazione intravascolare disseminata o una patologia psichiatrica/situazioni sociali che limiterebbero la conformità con i requisiti dello studio. 12. Donne in gravidanza o allattamento. 13. Il paziente presenta uno stato positivo noto per il virus dell’immunodeficienza umana o epatite B o C attiva o cronica (i pazienti con sierologia positiva per HBV possono essere arruolati e devono ricevere profilassi antivirale – i.e. lamivudina o entecavir). 14. Il paziente è dipendente dall'ossigeno. 15. Il paziente ha una qualsiasi condizione medica che, secondo il parere dello Sperimentatore, lo pone ad un rischio inaccettabilmente alto di tossicità. 16.
