Studio di IMGN632 in pazienti con BPDCN non trattato e BPDCN recidivato/refrattario

14 agosto 2026 aggiornato da: AbbVie

Uno studio di fase 1/2, multicentrico, in aperto sulla monoterapia IMGN632 somministrata per via endovenosa in pazienti con leucemia mieloide acuta CD123-positiva e altre neoplasie ematologiche CD123-positive

Questo è uno studio in aperto, multicentrico, di fase 1/2 per determinare l'MTD e valutare la sicurezza, la tollerabilità, la PK, l'immunogenicità e l'attività anti-leucemia di IMGN632 quando somministrato in monoterapia a pazienti con malattia CD123+.

Lo studio sta arruolando una coorte fondamentale di pazienti con BPDCN in prima linea e una coorte di pazienti con BPDCN recidivanti/refrattari.

Descrizione dettagliata

Lo studio ha completato una fase di escalation della dose e ora sta entrando in una fase di espansione della dose per caratterizzare ulteriormente il profilo di sicurezza e valutare l'efficacia di IMGN632 nei pazienti con BPDCN.

Descrizione

Criterio di inclusione:

  1. Caratteristiche della malattia:

    UN. Conferma della positività al CD123 mediante citometria a flusso o IHC. I partecipanti che hanno ricevuto in precedenza agenti mirati al CD123 saranno ammessi fintanto che le esplosioni hanno ancora un'espressione CD123 rilevabile.

  2. Inclusione di espansione:

    • Coorte 1 - Partecipanti con neoplasia a cellule dendritiche plasmacitoidi blastiche recidivante o refrattaria (BPDCN) con 1-3 precedenti linee di terapia
    • Coorte 6 - Partecipanti con BPDCN in prima linea allo screening che non hanno ricevuto una precedente terapia sistemica e partecipanti con BPDCN in prima linea che hanno PCHM e non hanno ricevuto una precedente terapia sistemica.

Nota: i partecipanti alla coorte 6 potrebbero aver ricevuto terapia locale (radioterapia, escissione chirurgica, terapia fotodinamica). I partecipanti idonei devono avere una recidiva o una progressione nel campo della terapia locale O una malattia al di fuori del campo della terapia locale.

Criteri di esclusione:

  1. I partecipanti che, a giudizio del proprio medico curante, dispongono di terapie standard di cura adeguate saranno esclusi dalle coorti da 1 a 5.
  2. Saranno esclusi i partecipanti BPDCN in prima linea con malattia del sistema nervoso centrale (SNC). Una puntura lombare deve essere eseguita durante il periodo di screening di 28 giorni, prima della somministrazione del farmaco. I partecipanti BPDCN recidivanti o refrattari con una storia nota di malattia del SNC devono essere stati trattati localmente, avere almeno 1 puntura lombare senza evidenza di malattia del SNC e devono essere clinicamente stabili prima della prima dose. La terapia concomitante per la profilassi del SNC o la continuazione della terapia per la malattia controllata del SNC è consentita con l'approvazione dello Sponsor.
  3. - Partecipanti con una storia di malattia veno-occlusiva del fegato.
  4. I partecipanti con una storia di sindrome da perdita capillare di grado 4 o edema di grado 4 non cardiaco non sono idonei, ad esempio, correlati a tagraxofusp-erzs o altra eziologia.
  5. Intervallo dalla precedente terapia antitumorale: 1. Per i partecipanti BPDCN in prima linea con precedente terapia locale (ad es. Radioterapia), i partecipanti non devono aver ricevuto trattamento entro 14 giorni prima della somministrazione del farmaco in questo studio. 2. I partecipanti BPDCN recidivanti o refrattari non devono aver ricevuto alcuna terapia antitumorale inclusa chemioterapia, immunoterapia, radioterapia, agenti ormonali, biologici o sperimentali nei 14 giorni precedenti la somministrazione del farmaco in questo studio. I partecipanti devono essersi ripresi al basale da tutta la tossicità acuta da questa precedente terapia.

Nota: l'eccezione che i partecipanti che hanno ricevuto un inibitore del checkpoint non devono aver ricevuto tale terapia entro 28 giorni prima della somministrazione del farmaco in questo studio.
