Pooled positive selection screens identified 474 activating and 738 mutations mediating resistance to the FGFR inhibitors pemigatinib and futibatinib, together revealing 301 druggable FGFR mutations analogous to a strong PS3/BS3 evidence level. The functional screens identified 97% of acquired resistance mutations in clinical trials. Our comprehensive catalog of every druggable mutation in the FGFR kinase domains is readily available for clinical decision support.

These findings suggest that tinengotinib might have activity in patients with cholangiocarcinoma with FGFR2 fusions that progressed following FGFR inhibitor therapy. Anti-tumour activity was also observed in patients with other FGFR alterations. The data from this phase 2 study supported the initiation of a phase 3 registration trial.

Advanced CCA remains largely inoperable, and combination gemcitabine plus cisplatin (GemCis) chemotherapy remains the standard treatment for patients affected by this disease...The FDA has approved the targeted therapies ivosidenib, pemigatinib, infigratinib, and futibatinib, as well as the immunotherapy durvalumab, for patients with CCA in recent years...While several promising advancements have been made, further research is required to improve outcomes for patients with CCA. This review provides an up-to-date, comprehensive overview of currently approved targeted therapies in CCA, as well as those under investigation.

Pan-FGFR-selective inhibitors (erdafitinib, pemigatinib, and futibatinib) have been developed in clinical practice...FGFR2-selective inhibitor lirafugratinib, FGFR3-selective inhibitors LOXO-435 and TYRA-300, FGFR2/3-selective inhibitor ABSK061, and FGFR4-selective inhibitors are in clinical development. Additionally, novel isoform-selective FGFR-targeting degraders, FGFR2b/FGFR3-selective antibodies, and de novo-designed 'c' isoform-selective proteins provide novel treatment strategies. This review provides an overview of the current FGFR-targeted therapeutics and limitations and evaluates next-generation inhibitor development to guide future research.

The article provides an overview of genetic alterations that are targetable with current oncological therapies, including FDA-approved inhibitors for FGFR2 (pemigatinib, futibatinib) and IDH1 (ivosidenib), along with inhibitors targeting BRAF, HER2, NTRK, and immunotherapies for MSI-high and TMB-high tumors. Intrahepatic CCA presents a broader spectrum of therapeutic targets, including rare fusions (ALK, RET), compared to perihilar and extrahepatic CCA, which share a poor prognosis and limited therapeutic options with pancreatic cancer. In this regard, intrahepatic CCA may become the "non-small cell lung cancer of gastrointestinal oncology."

If the tumour is unresectable, the recommended first-line treatment is cisplatin + gemcitabine + durvalumab a programmed cell death ligand 1 [PD-L1] inhibitor or pembrolizumab a programmed cell death protein 1 [PD-1] inhibitor. The development of targeted therapies has led to these treatments being recommended as second- or third-line therapy for patients with actionable gene alterations, while 5-fluorouracil-based chemotherapy is recommended for those without. Robust data support the use of ivosidenib in patients with IDH1 mutations (phase 3), and phase 2 trials showed efficacy of pemigatinib and futibatinib for patients with FGFR2 gene fusions, trastuzumab deruxtecan and zanidatamab for patients with HER2 overexpression/amplification, and dabrafenib + trametinib for patients with BRAFV600E mutations. It is hoped that wider dissemination of the content from this meeting will improve outcomes of patients with CCA by encouraging earlier referral, increasing the use of early molecular testing, an MDT approach, and maximising the use of targeted therapies. Continued efforts to raise awareness, implement education outreach opportunities, and involve patient advocacy groups are encouraged to improve CCA outcomes.

With a growing incidence of BTC and growing use of targeted therapies for FGFR2 alterations, the emergence of secondary resistance-causing point mutations following treatment with approved inhibitors is becoming increasingly challenging. Beyond selective inhibitors, lenvatinib may represent a viable therapeutic option.
