Fc-silent anti-TIGIT antibodies potentiate anti-tumor immunity without depleting regulatory T cells
(SITC 2023)
- P1 | "The ability of human TIGIT-specific clinical antibodies that are Fc-silent (domvanalimab) or Fc-enabled (AB308) to promote NK-mediated antibody-dependent cell-mediated cytotoxicity (ADCC) was evaluated using an in vitro co-culture system and by measuring absolute T cell counts in longitudinal peripheral blood patient samples from Phase 1 dose escalation clinical trials NCT03628677 and NCT04772989. Anecdotal clinical outcomes in two patients from NCT03628677 receiving domvanalimab in combination with an anti-PD-1 antibody, zimberelimab, are also reported...Conclusions We demonstrate that Fc-silent anti-TIGIT antibodies potentiate activation of tumor-specific T cells and anti-tumor efficacy without depleting Treg (figure 1). These data provide critical insights related to activity of anti-TIGIT antibodies lacking Fc functionality, such as domvanalimab."

Taiho Pharmaceutical Enters into a Clinical Trial Agreement with Arcus Biosciences and Gilead Sciences
(Taiho Press Release)
- "Taiho Pharmaceutical...announced today that it has entered into a Clinical Trial Agreement with Arcus Biosciences, Inc. ('Arcus') and Gilead Sciences, Inc. ('Gilead') related to the Arcus programs which Taiho had previously obtained rights to develop and commercialize in Japan and certain other territories in Asia (excluding China)....These optioned programs currently are the anti-TIGIT program (domvanalimab and AB308), the anti-PD-1 monoclonal antibody program (zimberelimab), and the adenosine receptor antagonist program (etrumadenant). The Clinical Trial Agreement is expected to further accelerate the development of these Arcus in-licensed products in Japan. Taiho will participate in two global phase 3 clinical trials, STAR-121 trial in non-small cell lung cancer, and STAR-221 trial in upper gastrointestinal tract cancer, both of which are expected to be initiated in Japan during 2023."

Anti-TIGIT antibodies promote immune activation relevant to targeting stem-like and tumor-specific T cells in combination with anti-PD-1
(IMMUNOLOGY 2022)
- "In mice, while combining Fc-silent or Fc-enabled anti-mouse TIGIT antibody with anti-PD-1 resulted in greater tumor growth inhibition than with anti-PD-1 alone, the activity of Fc-enabled anti-TIGIT was associated with intratumoral Treg depletion. These data provide a rationale for combination with immune-activating agents and support ongoing clinical evaluation of AB154 and AB308 with biomarker strategies focused on understanding the role of Fc functionality."

Arcus Biosciences Provides Update on Clinical Programs, Including Key 2022 Milestones
(Businesswire)
- "Anti-TIGIT program (domvanalimab and AB308): Anticipated 2022 Milestones: Data from ARC-7, an ongoing randomized 150-patient three-arm study in first-line PD-L1≥50% NSCLC, including progression-free survival data, are expected to be presented in 2H22. In addition to ARC-10, an ongoing registrational study in 1L PD-L1≥50% NSCLC, we and Gilead plan to initiate two new Phase 3 studies in lung and gastrointestinal (GI) cancers, as well as additional clinical studies of domvanalimab-based combinations, in 2022. AstraZeneca and Arcus will initiate the PACIFIC-8 registrational Phase 3 study in January to evaluate domvanalimab plus durvalumab, an anti-PD-L1 antibody, in unresectable Stage 3 NSCLC with curative intent, where durvalumab is standard of care. Data from the Phase 1/1b ARC-12 study evaluating AB308, an Fc-enabled anti-TIGIT antibody, plus zimberelimab in advanced malignancies will inform future development plans."

Gilead Exercises Options to Three Arcus Biosciences Clinical-Stage Programs and Adds Research Collaboration
(GlobeNewswire)
- "Gilead Sciences, Inc...and Arcus Biosciences, Inc...announced that Gilead has exercised its options to three programs in Arcus’s clinical-stage portfolio, including both anti-TIGIT molecules, domvanalimab and AB308, as well as etrumadenant and quemliclustat...The parties expect the transaction to close by year-end...Under the terms of the parties’ Option, License and Collaboration Agreement (the '2020 Agreement'), for the three options that Gilead is exercising today, Arcus will receive option payments totaling $725 million....Arcus may be required to operationalize at least 50% of the clinical studies, with costs to be shared by Gilead and Arcus. The royalties payable by Gilead to Arcus on sales for these three programs outside of the U.S. were slightly reduced. The reduced royalties range from the mid-teens to the low twenties....Upon closing of the transaction for all three programs, the $100 million option continuation payment due in 2022 will not be made by Gilead."
