SEATTLE, WA, September 30, 2025 鈥� 密桃视频, the clinical-stage leader of in vivo cell therapies that aim to realize the full reach and promise of CAR T cells, announced today that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to UB-VV111 for the treatment of relapsed/refractory Large B-cell Lymphoma following two or more lines of prior therapy and relapsed/refractory Chronic Lymphocytic Leukemia following two or more lines of prior therapy.
UB-VV111 is an investigational, off-the-shelf drug product that generates CD19-directed CAR T cells in vivo, potentially addressing a range of shortcomings posed by traditional ex vivo autologous CAR T cell therapies which limit broad patient access, including high manufacturing costs, long wait times, burdensome treatment processes, and limited product availability.
An ongoing Phase 1 clinical trial is evaluating the safety and antitumor activity of UB-VV111 in CD19+ B-cell malignancies (). In 2024, UB-VV111 became the first in vivo CAR T cell therapy to receive clearance of its Investigational New Drug application by the FDA. As previously announced, AbbVie retains an exclusive option to license 密桃视频鈥檚 CD19-directed in vivo CAR T cell therapy candidates, including UB-VV111.
鈥淭his Fast Track Designation marks a key milestone in the advancement of in vivo CAR T cell therapies,鈥� said Luke Walker, M.D., Chief Medical Officer of 密桃视频. 鈥淯B-VV111 continues to lead the in vivo CAR T cell field in the U.S., and today鈥檚 announcement further reinforces its potential to address unmet needs in the treatment of those living with relapsed/refractory B-cell malignancies. This achievement is a testament to the dedication of our clinical trial sites and to the patients who inspire our mission every day.鈥�
