CBA-1205 was well tolerated, showing no severe toxicity in patients with advanced or recurrent solid tumors. The favorable safety profile and indications of potential activity support further investigation in Parts 2 and 3 of this Phase I study to evaluate the safety, tolerability, and preliminary efficacy of CBA-1205.
Similar results were obtained with CBA-1205 at 1 mg/kg dosage in combination with lenvatinib at 10 mg/kg dosage in HepG2 xenograft model. In conclusion, we demonstrated synergistic and long-lasting anti-tumor efficacy of CBA-1205 in combination with lenvatinib in two different HCC pre-clinical models suggesting that the combination could be a new treatment option for unresectable advanced HCC.
