消息面上，据映恩生物官微消息，12月18日，映恩生物宣布，美国食品药品监督管理局(FDA)已授予映恩生物新一代靶向HER3抗体偶联新药DB-1310快速通道资格认定(Fast Track Designation，FTD)，用于治疗曾接受过内分泌治疗、CDK4/6抑制剂治疗，且在不可切除或转移性疾病阶段接受或未接受过化疗，或在完成辅助化疗期间或结束后6个月内出现疾病复发的成人晚期/不可切除或转移性激素受体(HR)阳性、人表皮生长因子受体2(HER2)阴性(免疫组化0、1+或2+/原位杂交阴性)乳腺癌患者。
据悉，DB-1310成为全球首款在此适应症上获FTD的HER3-ADC药物。DB-1310在HR+/HER2-乳腺癌中的FTD适应症范围较广，涵盖“在不可切除或转移性疾病阶段接受或未接受过化疗”的患者。这一广阔适应症的FTD认定将有助于推动DB-1310在HR+/HER2-乳腺癌未经化疗前线场景与化疗耐药后线场景两条主要路径上的关键临床开发。
