Rolontis, a neutropenia agent developed by Hanmi Pharmaceutical The US Food and Drug Administration has begun reviewing a medicine developed by South Korea’s Hanmi Pharmaceutical Co. for marketing authorization of the treatment of a white blood cell disease.The FDA will complete its review of the drug, Rolontis, by Sept. 9 in accordance with the Prescription Drug User Fee Act (PDUFA), Hanmi said on Tuesday.The US drug administration in August 2021 rejected an earlier marketing request by Spectrum Pharmaceuticals Inc., Hanmi’s US partner, of Rolontis, also known as eflapegrastim, citing manufacturing deficiencies at Hanmi’s drug substance facility in Korea. Hanmi Pharmaceutical headquarters Spectrum, a US biotechnology firm focused on novel and targeted oncology therapies, recently resubmitted a biologics license application (BLA) to the FDA, which accepted it after remediation of the Hanmi facility.Spectrum Chief Executive Tom Riga said the FDA’s acceptance of the BLA is important progress in the company’s efforts to bring the agent to the market and that he’s confident that the US drug agency will approve it.Kwon Se-chang, chief executive of Hanmi, said the company will closely cooperate with Spectrum for the approval and marketing of the drug. Hanmi's blockbuster high blood pressure drug Amosartan Rolontis, licensed out to Spectrum in 2012, is being developed for the treatment of chemotherapy-induced neutropenia, which occurs when a patient has too few neutrophils, a type of white blood cell. While all white blood cells help the body fight infections, neutrophils are important for fighting certain infections, especially those caused by bacteria.The molecule of the agent is manufactured by Hanmi at its biomanufacturing site in Korea.Hanmi, a leading pharmaceutical company in Korea, is also seeking to obtain the FDA’s marketing approval on its lung cancer medicine Poziotinib by the end of this year.By Do-Hee LeeTuxi0123@hankyung.comIn-Soo Nam edited this article.
