Undersøgelse af IMGN632 hos patienter med ubehandlet BPDCN og recidiverende/refraktær BPDCN

14. august 2026 opdateret af: AbbVie

Et fase 1/2, multicenter, åbent studie af IMGN632 monoterapi administreret intravenøst ​​hos patienter med CD123-positiv akut myeloid leukæmi og andre CD123-positive hæmatologiske maligniteter

Dette er et åbent, multicenter, fase 1/2-studie for at bestemme MTD og vurdere sikkerheden, tolerabiliteten, PK, immunogeniciteten og anti-leukæmiaktiviteten af ​​IMGN632, når det administreres som monoterapi til patienter med CD123+ sygdom.

Undersøgelsen inddrager en pivotal kohorte af BPDCN-patienter i frontlinjen og en kohorte af recidiverende/refraktære BPDCN-patienter.

Beskrivelse

Inklusionskriterier:

  1. Sygdomskarakteristika:

    en. Bekræftelse af CD123-positivitet ved flowcytometri eller IHC. Deltagere, der har modtaget tidligere CD123-målrettede midler, vil blive tilladt, så længe blasterne stadig har påviselig CD123-ekspression.

  2. Inkludering af udvidelse:

    • Kohorte 1 - Deltagere med recidiverende eller refraktær blastisk plasmacytoid dendritisk celle-neoplasma (BPDCN) med 1-3 tidligere behandlingslinjer
    • Kohorte 6 - Deltagere med frontline de novo BPDCN ved screening, som ikke har modtaget tidligere systemisk terapi og deltagere med frontline BPDCN, som har PCHM og ikke har modtaget tidligere systemisk terapi.

Bemærk: Deltagere i kohorte 6 kan have modtaget lokal terapi (strålebehandling, kirurgisk excision, fotodynamisk terapi). Støtteberettigede deltagere skal have et recidiv eller progression inden for lokalterapi ELLER sygdom uden for lokalterapiområdet.

Ekskluderingskriterier:

  2. Frontline BPDCN-deltagere med sygdom i centralnervesystemet (CNS) vil blive udelukket. En lumbalpunktur skal udføres i løbet af den 28-dages screeningsperiode, før lægemidlet indgives. Tilbagefaldende eller refraktære BPDCN-deltagere med en kendt historie med CNS-sygdom skal have været behandlet lokalt, have mindst 1 lumbalpunktur uden tegn på CNS-sygdom og skal være klinisk stabile før første dosis. Samtidig behandling til CNS-profylakse eller fortsættelse af terapi for kontrolleret CNS-sygdom er tilladt med sponsorens godkendelse.
  3. Deltagere med en anamnese med veno-okklusiv sygdom i leveren.
  4. Deltagere med en historie med grad 4 kapillær lækagesyndrom eller ikke-kardialt grad 4 ødem er ikke kvalificerede, f.eks. relateret til tagraxofusp-erzs eller anden ætiologi.
  5. Interval fra tidligere cancerbehandling: 1. For BPDCN-deltagere i frontlinjen med tidligere lokal terapi (f.eks. strålebehandling), må deltagerne ikke have modtaget behandling inden for 14 dage før lægemiddeladministration i denne undersøgelse. 2. Tilbagefaldende eller refraktære BPDCN-deltagere må ikke have modtaget nogen anti-cancerterapi, herunder kemoterapi, immunterapi, strålebehandling, hormonelle, biologiske eller andre forsøgsmidler inden for 14 dage før lægemiddeladministration i denne undersøgelse. Deltagerne skal være kommet sig til baseline efter al akut toksicitet fra denne tidligere behandling.

Bemærk: den undtagelse, at deltagere, der har modtaget en checkpoint-hæmmer, ikke må have modtaget denne behandling inden for 28 dage før lægemiddeladministration i denne undersøgelse.
