Targeting the immune environment in Acute Myeloid Leukemia

Official title: Targeting Acute Myeloid Leukemia Immunosuppressive Microenvironment by combinedIDO1 Inhibition and PD-1 Blockade

Run by IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT06874257 · Data updated 2026-11-12

This study is testing how the bone marrow environment affects treatment outcomes in people with Acute Myeloid Leukemia who are receiving azacitidine and venetoclax, to see if understanding this can improve immunotherapy.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older with a new diagnosis of AML who are ineligible for intensive chemotherapy and will receive azacitidine and venetoclax.

Probably not a fit

Patients with acute promyelocytic leukemia or those with known AML involving the central nervous system may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to investigate the cellular composition of the bone marrow microenvironment in patients with Acute Myeloid Leukemia (AML) before and after treatment with azacitidine and venetoclax. It will explore the role of the IDO1 enzyme and its impact on the immune response and treatment outcomes. By analyzing the relationship between the microenvironment and clinical responses, the study seeks to uncover mechanisms that contribute to treatment resistance and survival rates. The findings may help to better understand how to enhance immunotherapy effectiveness in AML.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with AML by enhancing the effectiveness of immunotherapy.

How similar studies have gone: While there have been studies exploring immunotherapy in AML, the specific combination of IDO1 inhibition and PD-1 blockade in this context is relatively novel and has not been extensively tested.
