What side effects are associated with this type of intervention?

Common treatments for Acute Leukemia, such as ivosidenib combined with azacitidine, venetoclax, and other chemotherapeutic agents, often have side effects including hematologic adverse events like neutropenia, anemia, and thrombocytopenia. Other notable side effects can include QT prolongation, differentiation syndrome, serious infections, hypersensitivity reactions, and prolonged cytopenias. These treatments aim to balance efficacy with manageable toxicity to improve patient outcomes.

What prior FDA approvals exist?

The FDA has approved several treatments for Acute Leukemia, including hypomethylating agents like azacitidine and decitabine, which are used for maintenance therapy. Oral azacitidine (CC-486) is approved for continued treatment of AML in patients unable to complete intensive curative therapy. IDH inhibitors and gemtuzumab ozogamicin are also approved for maintenance therapy. While decitabine is approved by the EMA for AML, it is not FDA-approved. These treatments aim to prolong remission and improve survival rates in acute leukemia patients.

What other types of research exist?

One promising alternative is DAB486IL-2, a recombinant fusion toxin that has shown significant activity in patients with chemotherapy refractory hematological cancers, including those expressing the p55 component of the IL-2 receptor. Another potential option is MK0974, a CGRP receptor antagonist that induces apoptosis in AML cell lines by disrupting ERK signaling. Both of these agents are in various stages of clinical evaluation and could be considered for treatment in 2024.

CAR T-cell Therapy

JNJ-75276617 for Acute Leukemia

Q: What is the mechanism of action of this treatment?

The most common treatments for Acute Leukemia include chemotherapy, targeted therapy, and immunotherapy. Chemotherapy works by using cytotoxic agents to kill rapidly dividing leukemia cells, but it also affects normal cells, leading to significant side effects. Targeted therapies, such as tyrosine kinase inhibitors, specifically inhibit abnormal proteins or pathways that drive leukemia cell growth, offering a more precise treatment with potentially fewer side effects. Immunotherapy leverages the patient's immune system to recognize and destroy leukemia cells, providing a novel approach that can be effective even in resistant cases. Understanding these mechanisms is crucial for patients as it helps in selecting the most appropriate treatment based on the specific characteristics of their leukemia, potentially improving outcomes and minimizing adverse effects.

Summary

This trial tests JNJ-75276617, an oral drug designed to block a protein interaction that helps leukemia cells grow. It targets patients with specific genetic types of AML or ALL. By stopping these proteins from working together, the drug aims to slow down or stop cancer cell growth.

Who is the study for?

This trial is for adults with acute leukemia who have specific genetic alterations (KMT2A or NPM1), and whose disease has not improved after treatment, or they can't receive standard treatments. They must be in relatively good health otherwise, with acceptable blood counts and organ function. Women of childbearing age and men must agree to use contraception.

What is being tested?

The study is testing JNJ-75276617 to find the safest dose that's also effective (Phase 2). It starts by increasing doses (Part 1) then tests this dose further for safety and effectiveness (Part 2).

What are the potential side effects?

While the side effects of JNJ-75276617 are being studied, potential risks may include reactions at the infusion site, changes in blood counts, liver issues, fatigue, nausea, and increased risk of infection.

Experimental Treatment

Group I: BleximenibExperimental Treatment1 Intervention

Participants in Phase 1 Part 1 (dose escalation) will receive bleximenib orally. The dose levels will be escalated based on the dose limiting toxicities (DLT) evaluation by Study Evaluation Team (SET) until the recommended Phase 2 Doses (RP2Ds) have been identified. Participants in Phase 1 Part 2 (dose expansion) will receive bleximenib orally at the RP2D(s) determined in Part 1. Food effect cohort (optional) participants will receive bleximenib orally on Cycle 2 Day 1 under fasted condition and on Cycle 2 Day 2 under fed condition. Participants in Phase 2 part of the study will receive bleximenib orally at the RP2D level(s).
