Major research findings
Futibatinib is a covalent FGFR1-4 inhibitor that has been shown to be effective in treating patients with advanced intrahepatic cholangiocarcinoma harboring FGFR2 gene fusions/rearrangements. 4 . It was approved by the US Food and Drug Administration (FDA) for this indication. 4 . Futibatinib is also effective against a broad spectrum of tumors, including cholangiocarcinoma, gastric, urothelial, central nervous system, head and neck, and breast cancer. 13 . It has shown to be particularly effective in patients with FGFR2 aberrations, including fusions, rearrangements, and copy number gains. 2 . In patients with FGFR2 fusions, futibatinib showed an overall response rate (ORR) of 42% and a median duration of response (DoR) of 9.7 months. 7 . Additionally, futibatinib demonstrates efficacy in overcoming FGFR1 mutant resistance in vitro and in vivo. 16 . This is significant because many FGFR inhibitors are ineffective against these mutations. 16 . Several studies evaluated the pharmacokinetics of futibatinib in healthy subjects and patients with different liver function impairments. Futibatinib was rapidly absorbed, with a median time to peak drug concentration of 1.0 hour. 6 . Futibatinib is mainly eliminated through feces, with minimal urinary excretion. 6 . No clinically relevant changes in futibatinib pharmacokinetics were observed in subjects with mild, moderate, or severe hepatic impairment. 4 . This suggests that dose adjustments are not necessary in patients with hepatic impairment. 4 . Futibatinib's effect on cardiac repolarization was also studied in healthy subjects. The study found that futibatinib did not prolong QTc interval at therapeutic or supratherapeutic doses. 10 . The study described in 12 investigated the role of Grb2 and PLCγ1 in BCR-FGFR1-driven cell proliferation. It was found that BCR-FGFR1 requires both Grb2 and PLCγ1 binding partners for cell proliferation. 12 . This suggests that targeting these interactions might be a promising therapeutic strategy. 12 .
Benefits and risks
Benefit summary
Futibatinib shows promise as a treatment for various types of cancer, particularly those with FGFR2 aberrations. 13 , 7 , 2 . It is well-tolerated by patients, even those with hepatic impairment. 4 . Furthermore, futibatinib does not significantly affect cardiac function. 10 .
Risk summary
Futibatinib can cause a number of side effects, including hyperphosphatemia, musculoskeletal pain, constipation, diarrhea, fatigue, dry mouth, alopecia, stomatitis, and abdominal pain. 7 . It can also lead to ocular toxicity, such as dry eye, keratitis, and retinal epithelial detachment. 7 .
Comparison of studies
Similarities between studies
Multiple studies confirm the effectiveness of futibatinib in treating cholangiocarcinoma with FGFR2 aberrations. 13 , 7 , 2 . Moreover, most studies indicate that futibatinib is effective against a wide variety of cancer types, including cholangiocarcinoma, gastric, urothelial, central nervous system, head and neck, and breast cancer. 13 .
Differences between studies
The efficacy of futibatinib may vary depending on the type of cancer and the specific patient. 13 . The side effects of futibatinib can also vary between patients. 7 .
Consistency and contradictions of findings
Multiple clinical trials support the effectiveness of futibatinib in treating patients with FGFR2 fusions or rearrangements. 13 , 7 , 2 . However, the data also suggest that not all patients respond to the treatment and that resistance can occur. 3 . It's important to remember that treatment response and side effects can vary between individuals. 13 , 7 .
Considerations for real-world application
While futibatinib shows promise in treating certain cancers, it's essential to understand that it is not a cure-all and can have significant side effects. 7 . Careful monitoring by a healthcare professional is crucial when considering futibatinib treatment. 7 .
Limitations of current research
The research on futibatinib is still ongoing and more studies are needed to fully understand its long-term effects, side effects, and interactions with other medications. 3 .
Future research directions
Further research is needed to assess the long-term effects and side effects of futibatinib. 3 . Investigating the combination of futibatinib with other therapies and exploring mechanisms of resistance are also important areas for future research. 3 .
Conclusion
Futibatinib demonstrates significant potential in treating certain cancers, particularly those with FGFR2 aberrations. 13 , 7 , 2 . It is well-tolerated and has a relatively safe profile. 4 . However, it is important to be aware of its potential side effects and to discuss the risks and benefits with a healthcare professional before starting treatment. 7 . Further research is needed to better understand futibatinib's long-term effects and potential for combination therapy.
