Now that the U.S. FDA has nearly 15 years of experience with developing and implementing a biosimilar pathway, it’s time for that regulatory path to catch up with the science, according to experts that have been involved in biosimilar development even before Congress passed the Biologics Price Competition and Innovation Act that created the framework for the U.S. biosimilar market.
The U.S. FDA’s concerns about the 510(k) program over the past decade-plus are practically the stuff of regulatory urban legend, but the agency has just unveiled a trio of draft guidances to address some of those concerns. Perhaps the most significant of these is a draft guidance for selection of a predicate device for a 510(k) filing, a document that may come across to industry as little more than an attempt to limit the devices that a manufacturer can recite in a 510(k) filing.
The U.S. FDA recently posted another round of recalls for the Cardiosave line of intra-aortic balloon pumps (IABPs) by Datascope Corp., advising users to make sure they have a backup unit at the ready in the case of device failure. However, the agency noted that “alternative treatments are limited,” a clear sign that this market lacks competition, most likely due to a lack of incentives for the private sector to invest in this class of devices.
Uniqure NV has received FDA clearance of its IND application for AMT-260, the company’s gene therapy candidate that represents a potential one-time administered approach to treating refractory mesial temporal lobe epilepsy (MTLE).
After hitting the safety and efficacy endpoints in a pivotal study of wet age-related macular degeneration (AMD), Outlook Therapeutics Inc.’s CEO said he had not expected to receive a complete response letter (CRL) from the U.S. FDA. The BLA for ONS-5010 (bevacizumab-vikg) now is on hold, the company said, because the agency said chemistry, manufacturing, and controls management problems were getting in the way, along with “open observations from pre-approval manufacturing inspections, and a lack of substantial evidence.”
The U.S. FDA has awarded Bristol Myers Squibb Co. (BMS) with its third approval for treating anemia with Reblozyl (luspatercept-aamt). Specifically, the approval is for treating anemia without previous erythropoiesis stimulating agent use in adults with very low- to intermediate-risk myelodysplastic syndromes who may require regular red blood cell transfusions.
Tscan Therapeutics Inc. has received FDA clearance of its IND application for TSC-203-A0201, a T-cell receptor (TCR)-engineered T-cell therapy (TCR-T) targeting preferentially expressed antigen in melanoma (PRAME). PRAME is expressed in melanoma and other solid tumors, including head and neck cancers and non-small-cell lung cancers. TSC-203-A0201 is specific for patients with HLA type A*02:01.
The U.S. FDA has given Aquedeon Medical Inc. the green light to conduct an IDE clinical trial of its Duett vascular graft system. The device is designed to improve outcomes in surgical thoracic aortic procedures by simplifying treatment of target vessels and reducing overall procedure time.
Harbour Biomed Ltd. has received FDA clearance of its IND application to commence a phase I trial of HBM-9033 in advanced solid tumors. Developed in collaboration with Medilink Therapeutics (Suzhou) Co. Ltd., HBM-9033 is an antibody-drug conjugate that specifically targets human mesothelin (MSLN), an upregulated tumor-associated antigen in various solid tumors, including mesothelioma, ovarian cancer, lung cancer, breast cancer and pancreatic cancers. The fully human monoclonal antibody in HBM-9033, generated from the Harbour Mice platform, binds preferably to membrane bond MSLN over soluble MSLN, which minimizes the interference of the shedding MSLN on the binding and internalization of the membrane bond MSLN.
