Combining Siltuximab with Chemotherapy for High-Risk Acute Myeloid Leukemia

Monocentric Phase 1 Study With Dose-escalation of Siltuximab in Combination With Idarubicin and Cytarabine Chemotherapy in Patients With Acute Myeloblastic Leukaemia (AML) With Poor Prognosis: SILTUXILAM

Phase 1 Interventional Nantes University Hospital · NCT05697510

This study is testing if adding a new drug called siltuximab to standard chemotherapy can help people with high-risk acute myeloid leukemia feel better and improve their treatment results.

What this trial studies

This phase 1 trial investigates the safety and efficacy of adding siltuximab, an anti-IL6 agent, to standard chemotherapy regimens for patients with high-risk acute myeloid leukemia (AML). Participants will receive siltuximab on day 8 of their chemotherapy, which includes idarubicin and cytarabine. The study aims to determine the optimal dose of siltuximab that can be safely administered alongside these chemotherapeutic agents. The trial focuses on patients with poor prognostic factors to assess potential improvements in treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with acute myeloid leukemia classified as having a poor prognosis.

Not a fit: Patients with specific genetic mutations eligible for targeted therapies or those with uncontrolled infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance treatment effectiveness and improve survival rates for patients with high-risk AML.

How similar studies have performed: While the combination of siltuximab with chemotherapy is a novel approach, previous studies have shown promise in targeting IL-6 in hematological malignancies.
