PF-06940434
PF-06940434 (ADWA-11) is a monoclonal antibody targeting integrin αvβ8. PF-06940434 inhibits αvβ8-mediated TGF-β activation. PF-06940434 increases the accumulation of tumor-infiltrating CD8+ T cells and upregulates the expression of granzyme B and TNF-γ. PF-06940434 blocks the inhibitory effect of CD4+CD25+ T cells on the cytotoxic activity of tumor CD8+ T cells. PF-06940434 enhances the anti-tumor efficacy of combination therapies with other immunomodulators or radiotherapy and induces long-term anti-tumor immunity. PF-06940434 can be used in the research of squamous cell carcinoma, breast cancer, colon cancer, and prostate adenocarcinoma.

PF-06940434 (0.067-66.67 pM) potently inhibits αvβ8-mediated cell adhesion to TGF-β1 latency-associated peptide in SNB19 human glioblastoma cells[1].
PF-06940434 (0.067-66.67 pM; 16 h) potently blocks αvβ8-mediated TGF-β activation in a co-culture system of SNB229 human glioblastoma cells and TMLC reporter cells[1].
PF-06940434 (48 h) blocks the suppressive effect of TRAMPC2 tumor-derived CD25+/CD4+ T cells on CD8+ T cell-mediated TRAMPC2 tumor cell killing in a 48-hour in vitro co-culture assay[1].

PF-06940434 (10 mg/kg; i.p.; days 0 and 7) monotherapy induces complete tumor regression in 10% of mice with mammary carcinoma, enhances intratumoral CD8+ T cell cytotoxic function, inhibits TGF-β signaling, and elicits long-term anti-tumor immunity[1].
PF-06940434 (10 mg/kg; i.p.; days 0 and 7) monotherapy potently inhibits prostate adenocarcinoma tumor growth, increases intratumoral CD8+ T cell accumulation and cytotoxic gene expression, and inhibits TGF-β signaling[1].
PF-06940434 (10 mg/kg; i.p.; days 0 and 7) inhibits prostate adenocarcinoma tumor growth and improves survival in wild-type littermate mice, with no additive effect in mice with T cell-specific Itgb8 deletion[1].
