Ficerafusp alfa
Based on 1 Customer Validation
Ficerafusp alfa (BCA-101; FMAB2) is a bifunctional antibody targeting EGFR and TGFβ, with a Kd of 2.58 nM for EGFR and a Kd value of 61.3 nM for TGFβ1. Ficerafusp alfa binds EGFR, inhibits EGFR phosphorylation, blocks EGF-dependent cell proliferation, and mediates antibody-dependent cellular cytotoxicity against EGFR-positive tumor cells. Ficerafusp alfa sequesters TGFβ through its TGFβRII ECD domain, neutralizes the activity of TGFβ and TGFβ1, and blocks TGFβ-dependent processes, including epithelial-mesenchymal transition, cell invasion, and induced regulatory T cell differentiation. Ficerafusp alfa can be used in research related to head and neck squamous cell carcinoma, advanced solid tumors, squamous non-small cell lung cancer, anal squamous cell carcinoma, colorectal cancer, and pancreatic cancer.

Result:Significantly reduced TGFβ-induced IL11 secretion, with IL11 concentrations lower than those in cetuximab and isotype control groups.\nSignificantly reduced IL11 secretion in A549 cells with established TGFβ-induced EMT, with IL11 concentrations lower than those in cetuximab and isotype control groups.
In Vivo
Ficerafusp alfa (50 mg/kg; i.p.; twice weekly) enhances the antitumor efficacy of anti-PD1 immunotherapy in a syngeneic melanoma model expressing human EGFR, conferring superior event-free survival compared with the monotherapy group[1].
Ficerafusp alfa (10 mg/kg; i.p.; twice weekly) acts synergistically with the Pembrolizumab (HY-P9902) monoclonal antibody, enhancing antitumor efficacy in a humanized prostate cancer xenograft model, with a TGI of 78% on day 18[1].
Ficerafusp alfa (10 mg/kg; intraperitoneal injection; 3 times per week; for 27 days) achieves sustained tumor growth delay in a head and neck squamous cell carcinoma PDX model in female NOG mice and neutralizes 90% of tumor TGFβ[3].
Ficerafusp alfa (intraperitoneal injection; 6 doses total) enhances the antitumor efficacy of PD-1 blockade therapy (Pembrolizumab, administered at 10 mg/kg once every 5 days for 5 doses total) in the PC-3 xenograft model in humanized Hu-NOG-EXL mice[3].

Animal Model:NOG mice[1]
-
Dosage:10 mg/kg
-
Administration:i.p.; twice a week; 27 days (PDX-1); 34 days (PDX-2); 32 days (PDX-3)
-
Result:In PDX-1, after 27 days of treatment and 52 days of follow-up, only 1 of 9 mice had tumor regrowth beyond initial 130 mm3 volume, compared with 6 of 10 mice in cetuximab group; mean tumor volume on day 79 was 67 mm3 vs. 146 mm3 for cetuximab.\nIn PDX-2, produced statistically significant lower mean tumor volume at treatment cessation (134 mm3 vs. 210 mm3 for cetuximab) and longer tumor doubling time (68 days vs. 47 days for cetuximab) after 34 days of treatment and 74 days of follow-up.\nIn PDX-3 (recurrent metastatic model), no tumors relapsed, compared with 2 of 10 mice in cetuximab group.

Animal Model:C57BL/6 mice[1]
-
Dosage:50 mg/kg (monotherapy; in combination with anti-PD1 mAb 10 mg/kg)
-
Administration:i.p.; twice a week
-
Result:As monotherapy, reduced the number of mice reaching a tumor volume ≥ 300 mm3 to 4 of 9, compared with 8 of 9 in the vehicle group.\nIn combination with anti-PD1 mAb, only 1 of 9 mice reached a tumor volume ≥ 300 mm3, superior to anti-PD1 monotherapy (3 of 9 mice) and cetuximab plus anti-PD1 combination (3 of 9 mice).\nThe combination produced a significant improvement in event-free survival (P=0.0034 vs. vehicle).
-
Animal Model:HuNOG-EXL humanized mice[1]
-
Dosage:10 mg/kg (monotherapy; in combination with pembrolizumab 10 mg/kg)
-
Administration:i.p.; twice a week
-
Result:As monotherapy, produced a 40% tumor growth inhibition (TGI) on day 18.\nIn combination with pembrolizumab, TGI increased to 78% on day 18, superior to the 52% TGI achieved with pembrolizumab monotherapy.\nAll treatments were associated with acceptable weight loss (≤ 15%).
