En undersøgelse af TAK-226 for transfusionsafhængig anæmi hos japanske patienter med lavrisiko myelodysplastiske syndromer

1. september 2026 opdateret af: Takeda

En fase 2, multicenter, åben-label, enarmet undersøgelse til evaluering af effektiviteten og sikkerheden af TAK-226 for transfusionsafhængig anæmi hos japanske patienter med meget lav-, lav- eller mellemrisiko myelodysplastiske syndromer

Hovedformålet med studiet er at evaluere, hvordan TAK-226 forbedrer symptomer på transfusionafhængig anæmi hos japanske patienter med myelodysplastiske syndromer af lavere risiko.

Studiet består af screeningsperioden (op til 6 uger), behandlingsperioden, sikkerhedsopfølgningen (8 uger) og langtidsopfølgningen (5 år fra den første dosis af undersøgelseslægemidlet eller 3 år efter den sidste dosis, alt efter hvad der er længst).

Deltagerne i dette studie vil få administreret TAK-226 under behandlingsperioden. Herefter vil deltagerne blive overvåget for bivirkninger relateret til studiebehandlingen under sikkerhedsopfølgningen og langtidsopfølgningen. Den omtrentlige deltagelsesvarighed for en deltager er op til ca. 6 år.

I løbet af studieperioden vil deltagerne besøge klinikken/sygehuset flere gange i henhold til studieplanen. Under behandlingsperioden vil deltagerne komme til klinikken/sygehuset ca. hver anden til fjerde uge.

    Bemærk: På grund af forventede virkninger af transfusion kan Hgb-værdier fra blodprøver indsamlet inden for 14 dage efter en RBS-transfusion og trombocytantal opnået inden for 7 dage efter en trombocyt-transfusion ikke bruges til at evaluere IPSS-R for berettigelse.

  4. Transfusionsafhængighed vurderet i de 16 uger umiddelbart før indskrivelse i to 8-ugers blokke klassificeret som enten:

    a. LTB, defineret som 4 til 7 RBS-enheder pr. 16 uger; eller b. HTB, defineret som ≥8 RBS-enheder pr. 16 uger; og c. For alle deltagere: i.

  5. Refraktær eller intolerant over for tidligere ESA-behandling (afbrudt ≥4 uger før indskrivelse), eller usandsynligt at svare på ESA-behandling, defineret som følger:

    a. Refraktær over for tidligere ESA-behandling: dokumentation af manglende respons eller et respons, der ikke længere blev opretholdt med et tidligere ESA-indeholdende regimen, enten som monoterapi eller kombination (f.eks. med granulocytkoloni-stimulerende faktor [G-CSF]); ESA-regimen skal have været enten: i. Rekombinant humant EPO ≥40.000 IU/uge i ≥8 doser eller tilsvarende; eller ii. Darbepoetin alfa ≥500 mcrg hver 3. uge i ≥4 doser eller tilsvarende. b.

An AE is any untoward medical occurrence in a clinical trial participant, temporally associated with the use of the trial intervention, whether or not the occurrence is considered related to the trial intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of the trial intervention. A TEAE is defined as an AE that commences on or after the first dose of the study treatment and within 60 days after the last dose of the study treatment, or analysis cutoff date, whichever is earlier. An SAE is any untoward medical occurrence that, at any dose: results in death, is life threatening, requires in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is a medically important event.

Plan for individuelle deltagerdata (IPD)

Planlægger du at dele individuelle deltagerdata (IPD)?

JA

IPD-planbeskrivelse

Takeda giver adgang til de-anonymiserede individuelle deltagerdata (IPD) for kvalificerede studier for at hjælpe kvalificerede forskere med at adressere legitime videnskabelige mål (Takedas datadelingstilsagn er tilgængeligt på https://clinicaltrials.takeda.com/takedas-commitment?commitment=5). Disse IPD'er vil blive leveret i et sikkert forskningsmiljø efter godkendelse af en anmodning om datadeling og under vilkårene i en datadelingsaftale.

IPD-delingsadgangskriterier

IPD fra kvalificerede undersøgelser vil blive delt med kvalificerede forskere i henhold til kriterierne og processen beskrevet på https://vivli.org/ourmember/takeda/. For godkendte anmodninger vil forskerne få adgang til anonymiserede data (for at respektere patienternes privatliv i overensstemmelse med gældende love og forskrifter) samt med de oplysninger, der er nødvendige for at adressere forskningsmålene i henhold til betingelserne i en datauddelingsaftale.
