Targeted and immunotherapy drugs for hepatocellular carcinoma (HCC) have been rapidly developed. Atezolizumab in combination with bevacizumab has been recommended as the first-line standard of care for unresectable or advanced HCC in several national and international guidelines. The combination therapies with sindilizumab and bevacizumab biosimilar, apatinib and carrilizumab, dulvalizumab and tremelimumab are also recommended as first-line standard regimens for advanced HCC in the guideline of Chinese Society of Clinical Oncology. Local therapy combined with targeted drugs (such as sorafenib and lenvatinib) or immune checkpoint inhibitors can significantly improve outcomes. Therefore, some progress has also been made in the study of single-agent or combination regimens as perioperative neoadjuvant therapy.

Gaucher disease is a lysosomal storage disease for which enzyme replacement therapy has proven to be effective. A switch-over clinical trial was performed to evaluate the efficacy and safety of Abcertin(R) (ISU Abxis, Seoul, Korea) in subjects with type 1 Gaucher disease who were previously treated with imiglucerase. Five Korean patients with type 1 Gaucher disease were enrolled. Previous doses of imiglucerase ranged from 30 to 55 U/kg every other week. The same dose of Abcertin(R) was administered to all patients for 24 weeks. Primary efficacy endpoints were changes in hemoglobin levels and platelet counts, and the secondary efficacy endpoints included changes in liver and spleen volumes, serum biomarkers, skeletal status and bone mineral density (BMD). During the study period, no statistically significant changes were observed in all parameters including hemoglobin levels and platelet counts, liver and spleen volumes, skeletal status and BMD. Abcertin(R) administration was continued in three patients for another 24 weeks as an extension of the study. Hemoglobin levels and platelet counts were maintained in all three patients. In conclusion, the efficacy and safety of Abcertin(R) are similar to those of imiglucerase, and Abcertin(R) is an effective therapeutic agent for patients with type 1 Gaucher disease (Clinical Trial Registry No. NCT02053896 at www.clinicaltrials.gov).

Worldwide sales of biologic drugs exceeded 100 billion USD in 2011. About 32% is from therapeutic monoclonal antibody (mAb). With many blockbuster biopharmaceutical patents expiring over the next decade, there is a great opportunity for biosimilar to enter the worldwide especially emerging market. Both European Medicines Agency (EMA) and Food and Drug Administration (FDA) have introduced regulatory frameworks for the potential approval of biosimilar mAb therapeutics. Rather than providing a highly abbreviated path, as in the case for small molecule chemical drug, approval for biosimilar mAb will require clinical trial and the details will be very much on a case-by-case basis. Since mAb is the dominant category of biologic drugs, mAb will be the focus of this review. First, the United States (US) and European Union (EU) approved mAb and those in phase 3 trials will be reviewed, then strategies on how to win biosimilar competition will be reviewed.
