Kymera Therapeutics, Inc. announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to KT-333 for the treatment of R/R Cutaneous T-cell Lymphoma (CTCL) and R/R Peripheral T-cell Lymphoma (PTCL). KT-333 is a highly selective degrader of STAT3 in development for the treatment of multiple STAT3-dependent pathologies, including hematological malignancies and solid tumors. STAT3 is a transcriptional regulator that has been linked to numerous cancers as well as to inflammatory and autoimmune diseases.

In 2022, KT-333 received FDA orphan drug designation for the treatment of both CTCL and PTCL. The FDA?s Fast Track process is designed to get important new medicines to patients more quickly, facilitating the development and expediting the review of therapies intended to treat serious conditions and address unmet medical needs. Companies whose programs are granted Fast Track designation are eligible for more frequent interactions with the FDA during clinical development and potentially accelerated approval and/or priority review, if relevant criteria are met.
