Recently, Kexing Biopharm (688136.SH) has completed the first dose of its long-acting GC product, Pegylated Human Granulocyte Colony-stimulating Factor Injection (hereinafter referred to as long-acting GC) developed in China, in all enrolled subjects in Phase I clinical study, showing favorable safety and tolerability.
Synergistically Promoting Long- and Short-Acting Drugs, Effectively Accelerating R&D
For patients with malignancies, the chemotherapy course is potentially associated with adverse reactions, including reduction or deficiency of neutrophils.
Human granulocyte-colony stimulating factor (G-CSF), a drug to increase white blood cell (WBC) count, is indicated for patients with non-bone marrow cancer to reduce the incidence of infections manifested by febrile neutropenia after administration of myelosuppressive anti-cancer drugs that are prone to cause clinically significant febrile neutropenia. With an increasing number of cancer patients, the market size for such drugs is gradually expanding.
Kexing Biopharm's long-acting GC shares the same pharmacological effects as G-CSF. With the assurance of maintaining clinical efficacy, the long-acting GC is empowered with diverse advantages, such as reducing the number of injections and outpatient visits, improving patients' compliance, and facilitating clinical convenience. Hence, it serves as another option for the treatment and prevention of febrile neutropenia after chemotherapy.
Prior to the development of the long-acting GC, Kexing Biopharm's Human Granulocyte Colony-stimulating Factor Injection (WHITE-C®), as a first-line WBC-stimulating drug with a wide range of evidence-based applications for over 20 years, has been marketed in many countries, and its market share has been continuously climbing. From 2018 to 2022, the compound annual growth rate (CAGR) of domestic and foreign sales revenue of WHITE-C reached 25.34%.
