Comment Period Extended on Synthetic Peptide Guide
Federal Register notice: FDA has extended the comment period on a 10/3 draft guidance entitled “ANDAs for Certain Highly Purified Synthetic Peptide Drug Products That Refer to Listed Drugs of rDNA Origin.” Comments can now be submitted in electronic or written form by 2/4/2018. The document is intended to help applicants determine when submission of ANDAs for complex peptides would be appropriate. It addresses glucagon, liraglutide, nesiritide, teriparatide, and teduglutide ANDAs that reference brand-name versions of these peptides manufactured using recombinant DNA technology. The recommendations in the new guidance are intended to help ensure that the risk of an immune response from the generic due to differences in impurities will not differ from that of the reference drug.
