In short
Pemigatinib is an innovative drug being studied in clinical trials for the treatment of various types of cancer. This article explores the use of pemigatinib in different clinical trials, focusing on its potential benefits for patients with cancers characterized by specific genetic alterations, particularly in the FGFR (Fibroblast Growth Factor Receptor) genes.

What is Pemigatinib?
Pemigatinib is a targeted cancer therapy drug. It is also known by the brand name Pemazyre or by its research code INCB054828. This medication is designed to treat specific types of cancers that have certain genetic changes in their cells.
How Does Pemigatinib Work?
Pemigatinib works by targeting and blocking proteins called fibroblast growth factor receptors (FGFRs), specifically FGFR1, FGFR2, and FGFR3. These proteins are involved in cancer cell growth and survival. By blocking these proteins, pemigatinib can help slow down or stop the growth of cancer cells.
What Cancers Can Pemigatinib Treat?
Pemigatinib is being studied for the treatment of various types of cancers, including:
- Cholangiocarcinoma (bile duct cancer): Pemigatinib is approved in Europe for treating a specific type of cholangiocarcinoma with FGFR2 alterations.
- Urothelial cancer (bladder cancer and cancers of the urinary system)
- Myeloid/lymphoid neoplasms (certain blood cancers)
- Other solid tumors with specific FGFR alterations, such as breast cancer, lung cancer, and soft tissue sarcomas
It's important to note that for many of these cancers, pemigatinib is still being studied and may not be approved for regular use yet.
How is Pemigatinib Administered?
Pemigatinib is taken orally (by mouth) as a tablet. The most common dosing schedule is:
- 13.5 mg once daily for 14 days, followed by 7 days off (21-day cycle)
Some studies are also looking at continuous daily dosing. Your doctor will determine the best dosing schedule for you based on your specific situation and how you respond to the treatment.
Effectiveness of Pemigatinib
The effectiveness of pemigatinib is measured in several ways in clinical trials:
- Objective Response Rate (ORR): This measures how many patients have a significant reduction in tumor size after treatment.
- Progression-Free Survival (PFS): This measures how long patients live without their cancer getting worse.
- Overall Survival (OS): This measures how long patients live after starting treatment.
- Duration of Response (DOR): This measures how long the cancer remains controlled after it starts responding to treatment.
The exact effectiveness can vary depending on the type of cancer and its specific genetic alterations. Your doctor can provide more specific information based on your individual case.
Side Effects and Safety
Like all medications, pemigatinib can cause side effects. Common side effects may include:
- High phosphate levels in the blood (hyperphosphatemia)
- Eye problems, including changes to the cornea and retina
- Fatigue
- Nausea and vomiting
- Diarrhea or constipation
- Changes in taste
- Mouth sores
Your doctor will monitor you closely for these and other side effects. They may adjust your dose or recommend treatments to manage side effects if they occur.
Ongoing Research
Pemigatinib is still being studied in many clinical trials. These studies are looking at its effectiveness in different types of cancers, different stages of disease, and in combination with other treatments. Some areas of ongoing research include:
- Using pemigatinib after surgery in cholangiocarcinoma to prevent cancer recurrence
- Combining pemigatinib with immunotherapy drugs
- Using pemigatinib in early-stage bladder cancer
- Studying pemigatinib in a wide range of solid tumors with specific genetic alterations
These ongoing studies will help researchers better understand how to use pemigatinib most effectively and safely in different situations.
