It’s unprecedented that Medicare doesn’t pay for a drug that received approval from the FDA,” even though it was not a full but an accelerated clearance.
A team of researchers at the National Cheng-Kung University in Taiwan has created monoclonal antibodies (MAbs) that can neutralize the secretory glycoprotein chitinase-3-like-1 (CHI3L1) to stop cancer growth.
A Japanese study has shown that targeting the chemokine receptor CCR4 using treatment with the monoclonal antibody mogamulizumab (Poteligeo, Kyowa, Amgen) depleted immune regulatory T cells and significantly improved survival in a canine model of advanced prostate cancer.
Celltrion Inc.’s Regkirona (regdanvimab), a monoclonal antibody treatment for COVID-19, received its latest approval from the European Commission (EC), making it the first Mab developed in South Korea to be approved there.
