再発・難治性（r/r）フィラデルフィア染色体陽性（Ph+）またはABLクラスPh様急性リンパ性白血病（ALL）の小児および若年成人におけるアスシミニブの安全性と有効性

2026年11月10日 更新者：Novartis Pharmaceuticals

小児、思春期、若年成人の再発または難治性BCR::ABL1陽性（フィラデルフィア染色体陽性、Ph+）またはBCR::ABL1様（Ph様）ALLにおける、アスシミニブと化学療法併用後のアスシミニブおよびブリナツモマブ併用療法の安全性と有効性を評価するためのオープンラベル第I/II相試験

Multi-center, open-label, single arm study of asciminib in participants aged ≥1 year to ≤30 years old with r/r Ph+ or ABL-class Ph-like ALL. This study will have 2 parts: Part 1 dose escalation and Part 2 dose expansion. Part 1 dose escalation will enroll participants aged ≥1 year to ≤30 years to determine the recommended phase 2 dose (RP2D) of asciminib when administered with low intensity chemotherapy. Part 2 dose expansion will enroll participants aged ≥1 year to ≤30 years to evaluate safety, tolerability, and efficacy of asciminib at the RP2D with the treatment regimen.

詳細な説明

This is a single arm phase I/II multicenter study to assess the safety and efficacy of asciminib at the RP2D in combination with low intensity chemotherapy (debulking induction) followed by asciminib plus blinatumomab (consolidation) in pediatric and young adult participants with r/r Ph+ ALL (inclusive of participants with T315I mutation).

The aim of the study design is to explore a novel treatment regimen which is expected to be more tolerable than the high intensity chemotherapy backbone-based regimens.

This study will consist of a 2-part design:

Part 1 dose escalation using a Bayesian Optimal Interval (BOIN) statistical design, and after determination of RP2D Part 2 dose expansion.

Participants will only enroll in either Part 1 or Part 2, and not both.

Both Part 1 and Part 2 (dose escalation and dose expansion) will have the following phases:

  • Core Study Treatment Phase
  • Survival Follow up Phase

Participants with known T315I mutation will not participate in Part 1 or Part 2. They will be part of a separate cohort.

The core study treatment phase will consist of 3 cycles of therapy: cycle 1 asciminib with low intensity chemotherapy (debulking induction), followed by cycle 2 (blinatumomab-block 1 with asciminib) and cycle 3 (blinatumomab-block 2 with asciminib).

Part 1 Dose Escalation: Incidence of Dose Limiting Toxicities (DLTs) occurring during cycle 1 (debulking induction)
時間枠：During Cycle 1 (Cycle 1 = 28 days)

A dose-limiting toxicity (DLT) is defined as an adverse event which starts between Day 1 and Day 28, is suspected by the investigator to be related to asciminib, and meets one of the several criteria.
During Cycle 1 (Cycle 1 = 28 days)
Part 1 Dose Escalation: Incidence and severity of adverse events (AEs) during cycle 1 (debulking induction)
時間枠：During Cycle 1 (Cycle = 28 days)

An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.
During Cycle 1 (Cycle = 28 days)
Part 2 Dose Expansion: Percentage of complete response/remission (CR) evaluable participants who achieve CR treated at recommended phase 2 dose (RP2D) (debulking induction)
時間枠：End of Cycle 1 (Cycle 1 = 28 days)

Participants with Complete Response/Remission (CR) will achieve the following:

No circulating blasts or extramedullary disease; No lymphadenopathy, splenomegaly, skin/gum infiltration, testicular mass/CNS involvement; Marrow <5% blasts (M1) OR < 1% blasts by flow cytometry. If a discrepancy occurs between disease detection methods, the result of the flow cytometry assay will be used to determine CR status; Peripheral blood count recovery; ANC > 1000μL and platelets > 100,000μL.

CR evaluable: Participants will be considered CR evaluable for Part 2 if they have relapsed/refractory Ph+ ALL defined as either >1% bone marrow (BM) blasts by MFC or immunoglobulin/T-cell receptor (IG/TCR) PCR, OR > 5% BM blasts by morphologic evaluation at enrollment and are treated at RP2D.
