- AGEN2373, a novel, potential best-in-class anti-CD137 antibody for the treatment of human malignancies, is well-tolerated in pre-clinical studies

LEXINGTON, Mass., Nov. 6, 2018 /PRNewswire/ -- Agenus Inc. (NASDAQ: AGEN), an immuno-oncology company with a pipeline of immune checkpoint antibodies, cancer vaccines, and adoptive cell therapies1, will present new data on several of its programs – including AutoSynVax™ (ASV™), discovery of a novel vaccine candidate for CRC and pre-clinical data on a novel anti-CD137 antibody – at the Society for Immunotherapy of Cancer's (SITC) 33rd Annual Meeting in Washington, D.C. November 7-11.

The three posters include:

  • Safety and tolerability data from a phase 1 trial of AutoSynVax™ (ASV™) in patients with advanced cancers. ASV is an individualized, fully synthetic neoantigen vaccine administered with QS-21 Stimulon® adjuvant.
  • Pre-clinical data on a novel, potential best-in-class anti-CD137 antibody (AGEN2373), designed for the treatment of human malignancies.
  • Discovery of novel phosphopeptide tumor targets (PTT), for developing off-the-shelf vaccine for CRC, with potential for pan-indication application

These programs build on Agenus' portfolio of antibodies directed to clinically validated targets such as CTLA-4 and PD-1, which are progressing towards a potential BLA as early as 2020.  Agenus' discovery platforms have delivered nine INDs from 2016 to first half of 2018.  Agenus is on track to advance four additional discoveries to IND by 1H 2019 – which would comprise a total of 13 INDs in three years, an immuno-oncology industry record. Because of Agenus' broad pipeline of I-O agents, the company is uniquely positioned to pursue novel combinations in the clinic.
