phase iii clinical trial scheme discussion of recombinant human erythropoietin -澳门凯发

recently, the phase iii clinical trial scheme discussion of recombinant human erythropoietin -fc fusion protein for injection (hereinafter referred to as "rhepo-fc fusion protein") jointly conducted by beijing new leading zhengzhou deep blue sea and shandong danhong pharmaceutical (a wholly-owned subsidiary of buchang pharmaceutical) was successfully held in the form of offline main venue (beijing) online video conference.

rhepo-fc fusion protein is a long-acting epo (erythropoietin) variety, and its indication is anemia caused by chronic renal failure or tumor chemotherapy. at present, the long-acting epo products listed in the world mainly include high glycosylation long-acting epo aranesp (and nesp) from amgen (and concord kirin) and pegylated long-acting epo mircera from roche. however, the domestic epo market is still dominated by short-acting epo, including yibiao, jimaixin, huanerbo and so on.

the rhepo-fc fusion protein is the first class 1 new drug of rhepo-fc with completely independent intellectual property rights in china, and it is the first to enter the phase iii clinical stage. phase iii clinical trial was led by professor zuo li, director of department of nephrology, peking university people's hospital, and nearly 40 centers in china participated in the study.

professor zuo li, director of the department of nephrology, peking university people's hospital, and more than 70 major researchers and institutional leaders from nearly 40 centers in china, as well as dr. the meeting was chaired by vice president zhang ronghuo. eneral manager of beijing buchang new drug research and development co., ltd., zhang ronghuo, new leading vice president of contract research organization in beijing and general manager of zhengzhou shenlanhai, lu xinghong, deputy general manager of clinical division, and relevant personnel of the project attended the meeting.

at the beginning of the meeting, dr. yang chun, general manager of beijing buchang new drug r&d co., ltd., the project sponsor, first introduced the background information of the project and the preparatory work in the early stage.
 

subsequently, dr. zhu haobin, director of beijing new leading zhengzhou deep blue sea medical department, elaborated on the research scheme in detail and had a heated discussion with all the participants. professor zuo li and the project team answered the questions one by one, which greatly improved the confidence of the participants.
 

in this seminar, all the participants showed a strong sense of responsibility, high professionalism and scientific and rigorous work style. i believe that in the upcoming phase iii clinical trial, beijing new leading zhengzhou deep blue sea will work together with researchers from more than 40 centers across the country to complete this research with high quality, high efficiency and intimacy in strict accordance with the latest regulations, which will add a lot of color to the research and development of new drugs in the field of long-acting epo in china.

 

epo project introduction
 

erythropoietin, epo) is a cytokine that promotes the proliferation and differentiation of bone marrow erythroid progenitor cells. the first generation of genetically engineered recombinant human erythropoietin (rhepo) drugs generally have the weakness of short half-life (4 ~ 8 hours), which requires 2-3 times or more per week to obtain curative effect, which brings inconvenience to its clinical application. al failure, tumor after radiotherapy and chemotherapy, multiple myeloma, myelodysplastic syndrome and anemia caused by aids.
 

in view of this, the research aimed at prolonging the plasma half-life and/or improving the biological activity of epo at home and abroad has never stopped. another way to prolong the serum half-life of epo is to prepare the fusion protein of epo and human igg fc (rhepo-fc). the mechanism of prolonging the half-life of this method is as follows: (1) the introduction of 1)fc increases the molecular weight of epo, reduces the glomerular filtration rate and prolongs the half-life; (2) after the introduction of fc, epo enters the endoplasmic body by endocytosis, and then combines with the intracellular fc recycling receptor to be released out of the cell, epo can be reused, thus prolonging the half-life of epo.
