Studie av IMGN632 hos pasienter med ubehandlet BPDCN og residiverende/refraktær BPDCN

14. august 2026 oppdatert av: AbbVie

En fase 1/2, multisenter, åpen studie av IMGN632 monoterapi administrert intravenøst ​​hos pasienter med CD123-positiv akutt myeloid leukemi og andre CD123-positive hematologiske maligniteter

Dette er en åpen, multisenter, fase 1/2-studie for å bestemme MTD og vurdere sikkerhet, tolerabilitet, PK, immunogenisitet og anti-leukemiaktivitet til IMGN632 når det administreres som monoterapi til pasienter med CD123+ sykdom.

Studien inkluderer en sentral kohort av BPDCN-pasienter i frontlinjen og en kohort med residiverende/refraktære BPDCN-pasienter.

Beskrivelse

Inklusjonskriterier:

  1. Sykdomsegenskaper:

    en. Bekreftelse av CD123-positivitet ved flowcytometri eller IHC. Deltakere som har mottatt tidligere CD123-målrettede midler vil bli tillatt så lenge blastene fortsatt har påvisbart CD123-uttrykk.

  2. Inkludering av utvidelse:

    • Kohort 1 - Deltakere med residiverende eller refraktær blastisk plasmacytoid dendritisk celle-neoplasma (BPDCN) med 1-3 tidligere behandlingslinjer
    • Kohort 6 - Deltakere med frontline de novo BPDCN ved screening som ikke har mottatt tidligere systemisk terapi og deltakere med frontline BPDCN som har PCHM og ikke har mottatt tidligere systemisk terapi.

Merk: Deltakere i kohort 6 kan ha mottatt lokal terapi (strålebehandling, kirurgisk eksisjon, fotodynamisk terapi). Kvalifiserte deltakere må ha residiv eller progresjon innen lokalterapi ELLER sykdom utenfor lokalterapifeltet.

Ekskluderingskriterier:

  1. Deltakere som, etter sin behandlende leges vurdering, har passende standardbehandlingsterapier, vil bli ekskludert fra kohorter 1 til 5.
  2. Frontline BPDCN-deltakere med sykdom i sentralnervesystemet (CNS) vil bli ekskludert. En lumbalpunksjon må utføres i løpet av den 28-dagers screeningsperioden før legemiddeladministrering. Tilbakefallende eller refraktære BPDCN-deltakere med en kjent historie med CNS-sykdom må ha blitt behandlet lokalt, ha minst 1 lumbalpunksjon uten tegn på CNS-sykdom, og må være klinisk stabile før første dose. Samtidig behandling for CNS-profylakse eller fortsettelse av terapi for kontrollert CNS-sykdom er tillatt med godkjenning av sponsoren.
  3. Deltakere med en historie med veno-okklusiv sykdom i leveren.
  4. Deltakere med en historie med grad 4 kapillærlekkasjesyndrom eller ikke-kardialt grad 4 ødem er ikke kvalifisert, f.eks. relatert til tagraxofusp-erzs eller annen etiologi.
  5. Intervall fra tidligere kreftbehandling: 1. For BPDCN-deltakere i frontlinjen med tidligere lokal terapi (f.eks. strålebehandling), må deltakerne ikke ha mottatt behandling innen 14 dager før legemiddeladministrering i denne studien. 2. Residiverende eller refraktære BPDCN-deltakere må ikke ha mottatt noen anti-kreftbehandling inkludert kjemoterapi, immunterapi, strålebehandling, hormonelle, biologiske eller andre undersøkelsesmidler innen 14 dager før legemiddeladministrering i denne studien. Deltakerne må ha kommet seg til baseline fra all akutt toksisitet fra denne tidligere behandlingen.

Merk: unntaket fra at deltakere som har mottatt en sjekkpunkthemmer ikke må ha fått den behandlingen innen 28 dager før legemiddeladministrering i denne studien.
