henlius publishes clinical data of bevacizumab biosimilar hlx04 in internationally renowned journals biodrugs and ccp

recently, henlius announced that the results of the phase 1[1]and phase 3[2]

clinical trials of hlx04, an independently developed bevacizumab biosimilar were published in two well-known journals, cancer chemotherapy and pharmacology (ccp) and biodrugs, respectively.

hlx04 is a bevacizumab biosimilar developed by henlius independently in accordance with technical guidelines for the development and evaluation of biosimilars (tentative), which can be used in the treatment of advanced, metastatic or recurrent non-small cell lung cancer(nsclc) and metastatic colorectal cancer(mcrc). hlx04 can block the interaction between vascular endothelial growth factor (vegf) and its receptors by binding with vegf specifically, which then inhibits tumour angiogenesis and thus suppressing the growth and metastases of tumours[3]. henlius has conducted multiple head-to-head comparisons between hlx04 and the reference bevacizumab including the analytical and preclinical study, phase 1 and phase 3 clinical studies. the results showed that hlx04 was highly similar to the reference bevacizumab in terms of quality, safety and efficacy.

the leading principal investigator of this muti-centre, randomised, double-blind, four-arm, parallel-controlled phase 1 study was yanhua ding, m.d. from the first hospital of jilin university. the clinical data were first presented at the 21st annual meeting of chinese society of clinical oncology (csco) in 2018.  the results demonstrated that hlx04 had similar pharmacokinetic and safety profiles to the reference bevacizumab sourced from the united states (bevacizumab-us), the european union (bevacizumab-eu) and china (bevacizumab-cn), supporting the confirmatory phase 3 study investigating the efficacy and safety equivalence between hlx04 and bevacizumab in patients with mcrc.

different from currently approved bevacizumab biosimilars in china, the phase 3 study of hlx04 was conducted among chinese patients with mcrc, which helps to accumulate more clinical evidence and experience of bevacizumab in this patient population. shukui qin from nanjing bayi hospital of chinese people's liberation army and jin li from shanghai east hospital are co-leading principal investigators of this study. this study had reached its primary and secondary endpoints in august 2020. the study results were presented  by professor jin li as an oral presentation at the csco 23rd annual meeting, which won the outstanding award. 

hlx04-mcrc03(nct03511963) is a multi-centre, randomised, double-blind, parallel-controlled phase 3 study aimed to compare the efficacy, safety and immunogenicity of hlx04 to the reference bevacizumab in combination with chemotherapy (xelox or mfolfox6) as a first-line treatment in patients with mcrc. the primary endpoint was progression-free survival rate at week 36 (pfsr36wk) per recist v1.1. secondary endpoints included the evaluations of efficacy, safety, immunogenicity, and pharmacokinetics. a total of 677 patients were randomised in this study (hlx04, n = 340; bevacizumab, n = 337). pfsr36wk was 46.4% (95% confidence interval [ci]: 41.1%, 51.8%) in the hlx04 group and 50.7% (95% ci:  45.4%, 56.1%) in the bevacizumab group. the rate difference (−4.2%, 90% ci: -10.6% to 2.1%) and rate ratio (0.92, 90% ci: 0.8, 1.05) both fell within the prespecified equivalence margins. the results of the phase 3 study demonstrated the efficacy equivalence between hlx04 and the reference bevacizumab with similar safety and immunogenicity profiles as a first-line treatment for mcrc patients. hlx04 will provide an alternative treatment option for mcrc patients as a potential biosimilar candidate.

publication of the results from the two hlx04 clinical trials again provided strong evidence for the efficacy and safety similarity between hlx04 and the reference bevacizumab. as of now, henlius has submitted the new drug application (nda) of hlx04 to the national medical products administration (nmpa) for the use of hlx04 in advanced, metastatic or recurrent nsclc and mcrc patients, and has received nda acceptance notification from the nmpa. we expect that hlx04 will benefit more tumour patients as soon as possible as a high-quality and affordable treatment option.
