When TIGIT is combined with other immunotherapies, the TIGIT targeting proves to be more effective. TIGIT has a broad expression on lymphocytes, thus making it a crucial immune checkpoint with the potential to inhibit each step of the cancer immunity circle.
TIGIT, short form for T-cell immunoreceptor with Ig and ITIM domains, is a transmembrane glycoprotein receptor made of Ig-like V-type domain within its cytoplasmic domain and an ITIM in its extracellular domain. Several clinical studies having combination treatments have been started that study TIGIT-blockade in cancer. These clinical studies have proved TIGIT to be a suitable target for cancer treatment. Presently, there are six active clinical trials whose outcomes are eagerly anticipated.
Recent Collaboration Assessment:
- In 2018, AstraZeneca purchased an exclusive license to COM902 for the development of multi-specific and bispecific antibody products.
- In May 2020, Gilead and Arcus agreed on co-developing and co-commercializing anti-TIGIT domvanalimab.
- In May 2021, Bristol Myers Squibb purchased an exclusive license to Agenus’ AGEN1777, a bispecific antibody that blocks TIGIT and a second undisclosed target.
- In June 2021, iTeos Therapeutics and GlaxoSmithKline agreed on co-developing and co-commercializing EOS-488, an anti-TIGIT monoclonal antibody. EOS-488 is phase I as of now, and can be a potential treatment for cancer patients.
