Last week, China’s State Food and Drug Administration (SFDA) Drug Registration Department Director Zhang Wei was interviewed by the Xinhua news bureau about the upcoming 2009 SFDA annual report. He revealed some interesting statistics about approvals as well as clinical trial activities.
In response to the H1N1 epidemic, the SFDA initiated an expedited review process. This resulted in the approval of 10 different H1N1 vaccines in 2009. Tamiflu (oseltamivir phosphate capsules) received approval for scaled-up manufacturing as well as new indications to include special populations and pediatric use. Expedited approval was also granted for the import of By Le-Wei (zanamivir powder for inhalation).
For HIV therapy, Zhang reported that key pharmaceuticals in currently accepted regimens are now available, and some of these are manufactured in China. The approval of nevirapine, zidovudine and lamivudine will go a long way in managing the disease and disrupting maternal-fetal transmission of the virus.
In oncology, the approval of Tasigna (nilotinib) for CML patients offers an alternative for those who are resistant to Gleevec (imatinib mesylate) treatment. Felodipine, developed in China, entered clinical trials.
For hepatitis B, a major health concern in China, Zhang noted that the approval of generic entecavir will reduce cost and improve access. Similarly, in CV drugs, the generic version of levosimendan was approved, and the generic paliperidone entered clinical trials. In diabetes, a dipeptidyl peptidase-4 (DPP-4) inhibitor for type II diabetes, was approved. In antimicrobials, Cubicin (daptomycin) was approved. Several traditional Chinese medicine (TCM) drugs also received approval. These approvals cover several categories including respiratory and women’s health.
All told, the SFDA approved 2,609 drug applications covering 1,464 different products in 2009. Nine of these are new drug entities that became available for the first time on a worldwide basis. And 69 of the new products are TCM entities. The overall approval rate is at 40 percent, holding steady for the past three years. (By comparison, the approval rate was closer to 90 percent in previous years.)
On the clinical trials front, the SFDA approved the initiation of 773 trials for 627 pharmaceuticals, 81 TCM entities and 64 biologicals, most of them in the anti-infective, oncology, cardiovascular and other chronic disease categories.
