What data supports the effectiveness of the drug Pemigatinib for treating Acute Myeloid Leukemia?

The research highlights the effectiveness of daunorubicin and cytarabine, which are part of the treatment regimen for Acute Myeloid Leukemia, showing a 56% response rate in a study with a combination therapy. While Pemigatinib is not directly studied here, the effectiveness of similar drugs in combination therapies suggests potential benefits. ^{1 2 3 4 5}

Is Pemigatinib safe for use in humans?

The safety data for cytarabine and daunorubicin, which are used in treating acute myeloid leukemia, show that while they can cause side effects like nausea, vomiting, and liver and kidney issues, these are generally manageable. Serious complications are infrequent, and the treatment is considered well-tolerated in many patients. ^{6 7 8 9 10}

What makes the drug pemigatinib unique for treating acute myeloid leukemia?

Pemigatinib is unique for treating acute myeloid leukemia because it represents a novel approach compared to traditional chemotherapy regimens like cytarabine and daunorubicin, which have been standard for decades. While traditional treatments focus on cytotoxic effects, pemigatinib may offer a different mechanism of action, potentially targeting specific pathways involved in the disease. ^{10 11 12 13 14}

What is the purpose of this trial?

This phase I trial identifies the best dose and clinical benefit of giving pemigatinib following standard induction chemotherapy in patients with newly diagnosed acute myeloid leukemia. Pemigatinib selectively inhibits FGFR (fibroblast growth factor receptor) activity, a receptor that may contribute to the growth of leukemia cells. The genetic changes responsible for activating the growth of leukemia cells can be unique to each patient and can change during the course of the disease. Chemotherapy drugs, such as cytarabine and daunorubicin work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

Findings from Research

The DAF regimen, which includes daunorubicin, fludarabine, and cytarabine, showed a 56% overall response rate in 34 patients with relapsed or refractory acute myeloid leukemia (AML), with 15 out of 16 patients achieving complete remission after the first course.

The treatment was well tolerated, with severe neutropenia and serious infections occurring in a significant number of patients, but no severe long-term complications like liver or kidney failure were observed, indicating a favorable safety profile for this regimen.

In a study of adult patients with acute myeloid leukemia (AML) receiving the '7 + 3' induction therapy, 59% achieved remission, but many required multiple induction courses, leading to prolonged myelosuppression and increased infection rates.

High-dose cytarabine (HDARA-C) consolidation significantly improved disease-free survival for patients who achieved remission, while the myelosuppression and infection risks were comparable to those seen with single induction courses.

The study found significant variations in how acute myeloid leukemia (AML) patients respond to the chemotherapy drug cytarabine (Ara-C), with some patients being sensitive and others resistant based on their gene expression profiles.

Higher expression levels of certain genes like deoxycytidine kinase (DCK) and ribonucleotide reductase M1 (RRM1) were associated with better treatment outcomes, while a newly proposed Ara-C resistance index (RI) could help predict drug response and potential treatment toxicity.

Recent advancements in acute myeloid leukemia (AML) treatment have introduced new drugs like gemtuzumab and midostaurin, which are more effective for specific AML subtypes, challenging the traditional '3+7' chemotherapy approach.

While lower intensity therapies show high response rates, they are less effective at preventing relapses, and the only curative option for poor-risk AML remains allogeneic stem cell transplant, indicating that '3+7' still plays a crucial role in combination therapies for suitable patients.

The combination of 5-Aza-2'-deoxycytidine (DAC) and cytarabine (ara-C) demonstrated either additive or synergistic effects on cell death in various human leukemia cell lines, indicating a potential for enhanced efficacy in treating acute myeloid leukemia.

While DAC and ara-C together increased cell death, they exhibited antagonistic effects on epigenetic regulation, suggesting that hypomethylated cells may be more sensitive to ara-C, which could inform treatment strategies.
