LAVA Therapeutics B.V. to Present Preclinical Findings Supporting Anti-Tumor Activity of Lead Clinical Candidate LAVA-051 at the American Association for Cancer Research (AACR) Virtual 2021 Annual Meeting

The following abstract is now available on the AACR website at www.aacr.org.

Title: Potent anti-tumor activity against patient CLL, MM and AML cells by LAVA-051, a bispecific Vγ9Vδ2-T and type 1 NKT cell engager targeting CD1d
Session Type: E-Poster Session
Session Title: Therapeutic Antibodies, Including Engineered Antibodies
Abstract Number: 1855

LAVA-051 is a humanized gamma-delta bsTCE which targets CD1d and the Vδ2 domain of the T cell receptor. It is the first antibody-based compound targeting CD1d to activate both Vγ9Vδ2-T and type 1 NKT cells. LAVA-051 exerted substantial antitumor activity against patient derived acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) cells that express CD1d. In addition, improved survival was observed in in vivo AML and MM mouse xenograft models treated with LAVA-051.

LAVA-051 is planned to enter a Phase I/IIa study in hematologic malignancies in 1H 2021.
