This study is designed to compare the anti-tumor effects and adverse effects between engineered exosomes carrying HER2 siRNA and trastuzumab. The stable cell line of iRGD-293T was constructed by using lentiviruses, and iRGD-293T and 293T cells were transfected with si-HER2 and exosomes were isolated by ultra-centrifugation. Functional experiments were performed to examine the inhibitory effects of iRGD-exo-si-HER2 and trastuzumab on both HER2-positive GC cells and mouse xenograft models. Blood biochemical indexes were used to test the adverse effects, especially cardiotoxicity. The engineered exosomes modified by iRGD peptide showed higher tumor affinity compared to control exosomes in vitro and in vivo. si-HER2 delivered by iRGD-exosomes significantly inhibited the proliferation and promoted apoptosis of HER2-positive GC cells, and iRGD-exo-si-HER2 significantly reduced the expression of HER2 in GC cells in vitro and in vivo, showing similar efficacy as trastuzumab but with lower cardiac side effects. Our data indicated that iRGD-exo-si-HER2 shows good anti-tumor effect both in vivo and in vitro, and has fewer side effects compared with trastuzumab.

We examined this issue through a case study of isotretinoin, an established standard drug for high-risk neuroblastoma (affecting 45-60 new patients annually in Japan) since the 2000s that has not been granted regulatory approval in Japan as of 2025. Analysis of regulatory documents and clinical practices revealed that while isotretinoin has demonstrated improved event-free survival rates in international trials when used as maintenance therapy for high-risk neuroblastoma, multiple barriers have hindered its domestic approval. These include the challenges of conducting clinical trials in limited pediatric populations, substantial development costs, diminishing market attractiveness due to Japan's demographic shift, and restrictions on \"mixed billing system\" which means combining covered insurance treatments with uncovered treatments under the universal health insurance system in Japan. Currently, patients must rely on costly private imports or clinical trial participation to access the drug, leading to financial burdens and treatment discontinuation risks. Recent regulatory reforms, including the establishment of the Evaluation Committee on Unapproved or Off-labeled Drugs with High Medical Needs in 2009 and amendments enabling investigator-led trials, have facilitated progress. An investigator-led Phase II clinical trial evaluating isotretinoin's safety and efficacy is ongoing since 2023, with expected completion in 2026.
