Description: Fenebrutinib, also known as GDC-0853, is orally available inhibitor of Bruton's tyrosine kinase (BTK) with potential antineoplastic activity. Upon administration, GDC-0853 inhibits the activity of BTK and prevents the activation of the B-cell antigen receptor (BCR) signaling pathway. This prevents both B-cell activation and BTK-mediated activation of downstream survival pathways, which leads to the inhibition of the growth of malignant B-cells that overexpress BTK. BTK, a member of the Src-related BTK/Tec family of cytoplasmic tyrosine kinases, is overexpressed in B-cell malignancies; it plays an important role in B-lymphocyte development, activation, signaling, proliferation and survival.

Biological target: Fenebrutinib (GDC-0853) is a bruton's tyrosine kinase (Btk) inhibitor with Kis of 0.91 nM, 1.6, 1.3, 12.6, and 3.4 nM for WT Btk, and the C481S, C481R, T474I, T474M mutants.
In vitro activity: In isolated primary human B cells, GDC-0853 potently inhibited anti-IgM-induced Btk Y223 tyrosine phosphorylation (IC50 = 3.1 nM) and anti-IgM and CD40L-induced B-cell proliferation (IC50 = 1.2 nM and 1.4 nM, respectively) (Table 8). Btk inhibition by GDC-0853 prevented FcγRIII-triggered TNFα production in human monocytes (IC50 = 1.3 nM). In human blood, GDC-0853 potently inhibited up-regulation of the early activation marker CD69 on B cells after overnight anti-IgM stimulation (IC50 = 8 nM). Furthermore, GDC-0853 also suppressed anti-IgM induced Btk Y223 autophosphorylation in human whole blood (IC50 = 11 nM). Taken together, these data demonstrate that GDC-0853 is a highly selective Btk inhibitor that blocks both B-cell BCR and monocyte FcγR signaling.

In vivo activity: To evaluate the in vivo efficacy of GDC-0853, it was tested in a B and myeloid cell-dependent inflammatory arthritis model. Female Lewis rats with developing collagen-induced arthritis were dosed orally for 16 days with GDC-0853 at a range of doses once (0.06, 0.25, 1, 4, and 16 mg/kg QD) (Figure 8A) or twice (0.125, 0.5, and 2 mg/kg BID) daily (Figure 8B). GDC-0853 dose-dependently reduced ankle thickness following QD (Figure 8A) and BID (Figure 8B) dosing regimens. Furthermore, GDC-0853 showed a dose responsive beneficial effect on a panel of ankle histopathology parameters (inflammation, pannus, cartilage damage, bone resorption; data not shown).
