Incyte Announces Japanese Approval of Pemazyre (pemigatinib) for the Treatment of Patients with Myeloid/Lymphoid Neoplasms (MLNs) - Seite 2

MLNs with FGFR1 rearrangement are a form of very rare hematological cancers caused by a chromosomal abnormality (translocation) in which the chromosome breaks where the FGFR1 gene is located (position 11 in the short arm of chromosome 8: location 8p11) and fuses with fragments (genes) of other chromosomes. Various partner genes cause a constitutive activation of the FGFR1 tyrosine kinase, impacting cell proliferation and survival. These cancers are largely divided into two phases according to clinical presentation: the chronic phase, if diagnosed as myeloproliferative disorder or myelodysplastic syndrome, or acute phase, if diagnosed as acute leukemia. The prognosis is unfavorable, and while allogenic hematopoietic stem cell transplant is considered to be the only currently available treatment option that may achieve cure or long-term remission, no standard of care has been established.

About FIGHT-203

FIGHT-203 is a Phase 2, multicenter trial that enrolled patients 18 years and older with myeloid/lymphoid neoplasms (MLNs) with a fibroblast growth factor receptor 1 (FGFR1) rearrangement. Sponsored by Incyte, the study evaluated the safety and efficacy of pemigatinib for the treatment of adults with MLNs with FGFR1 rearrangement. Patients received pemigatinib 13.5 mg once daily in 21-day cycles, either on a continuous schedule (the approved recommended starting dosage for use in patients with MLNs with FGFR1 rearrangement) or as an intermittent schedule (14 days on, 7 days off, an unapproved dosage regimen in MLN with FGFR1 rearrangement). Pemigatinib was administered until disease progression or unacceptable toxicity or until patients were able to receive allo-HSCT.

About Pemigatinib

Pemazyre is a kinase inhibitor indicated in the United States for the treatment of adults with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion or other rearrangement as detected by an FDA-approved test². This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).
