What You Need to Know Before You Apply

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.

Do I have to stop taking my current medications for the trial?

The trial protocol does not specify if you must stop taking your current medications. However, you cannot use certain medications that strongly affect liver enzymes (CYP3A4 inducers) within 14 days before starting the study drug. It's best to discuss your current medications with the trial team.

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. ^{1 2 3 4 5}

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. ^{5 6 7 8 9}

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. ^{10 11 12 13 14}

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.
