We are striving to fulfill our mission,to make cancer manageable and curable,and add new dimensions to biotechnology through innovation,including the development of subcutaneous administration,investigating new options for PD-(L)1 refractory NSCLC,or indications with inadequate response,including pancreatic cancer,thymic cancer etc.,and bring hope to more oncology patients."
Business Highlights
Since April 20,being the latest practicable date of the Company's 2020 annual report,we have been making significant progress with respect to our drug pipeline and business operations.
Product Pipeline
Our highly differentiated in-house pipeline consists of tumor monoclonal antibodies,bispecific antibodies,and one COVID-19 multifunctional antibody. Among our pipeline products,we have one biologics license application ("BLA") submitted,three in late clinical stage,and three in schedule for investigational new drug ("IND") submission.
KN046 (PD-L1/CTLA-4 bispecific antibody)
Several pivotal clinical trials are currently being conducted,including Phase III clinical research of KN046 in combination with chemotherapy for the treatment of sqNSCLC.
Events during the Reporting Period
On April 29,we entered into a clinical trial collaboration and supply agreement with Pfizer Inc. to evaluate the efficacy and safety of KN046 in combination with Inlyta (axitinib) for the first-line treatment of NSCLC.
Data from a Phase II study (KN046-IST-04) of KN046 plus nab-paclitaxel/gemcitabine as first-line treatment for pancreatic ductal adenocarcinoma (PDAC) was presented at ASCO 2021,which indicated good tolerability. The ORR was 55.6%,and DCR was 88.9%.
Data from the Phase II clinical study of KN046 combined with platinum doublet chemotherapy for the treatment of patients with advanced NSCLC is presented at ASCO 2021. The results show that KN046 combined with platinum doublet chemotherapy is well tolerated and has shown promising clinical benefit as IL treatment for stage IV NSCLC particularly in PD-L1≥1% tumors and squamous histology. The Phase III clinical study of KN046 combined with chemotherapy for the treatment of sqNSCLC is ongoing.
Data from Phase 2 clinical study of KN046 plus paclitaxel/cisplatin for the first-line treatment of unresectable locally advanced,recurrent or metastatic ESCC is presented at ASCO 2021. Tolerability was good,and the ORR was 58.3%,and the DCR was 91.6%.
Expected milestones for 2021
Data from several clinical studies of KN046 will be presented at the ESMO Congress 2021.
Updated results from phase II clinical study of KN046 plus nab-paclitaxel/gemcitabine as first-line treatment for unresectable locally advanced or metastatic PDAC will be presented at an upcoming medical meeting. Phase III clinical study of KN046 in combination with chemotherapy for the first line treatment of pancreatic cancer will be launched this year.
To complete enrollment and generate interim readout for ENREACH-LUNG-01: KN046+chemo,1L sq-NSCLC.
To complete the Chinese enrollment for ENREACH-THYMIC: KN046,≥2L thymic carcinoma.
To initiate pivotal trial: KN046+lenvatinib,PD-(L)1 refractory NSCLC.
To complete the US FDA EoP2 Communication: KN046+Lenvatinib,1L HCC.
KN026 (a next-generation anti-HER2 BsAb)
It can simultaneously bind two distinct clinically validated epitopes of HER2,resulting in potentially superior efficacy.
Events during the Reporting Period
We made advancement in evaluating the preliminary efficacy of KN026 in advanced GC/ GEJ patients with HER2 expression,which indicated that KN026 demonstrated favorable safety and promising efficacy in Chinese HER2 over expressing GC/GEJ patients pretreated with or without anti-HER2 treatments. Such results were presented at the 2021 ASCO.
Events after the Reporting Period and Expected milestones for 2021
In August 2021,the Company completed the first drug administration in a phase II clinical study of KN026 for the neoadjuvant treatment of HER2 positive early or locally advanced breast cancer. The phase II multicenter clinical study aims to evaluate the efficacy,safety and tolerability.
In August 2021,the Company received a notice of approval for supplementary application for drug clinical trials from the NMPA,which approved the supplementary application for the pharmaceutical change of KN026 to use a liquid formulation for clinical research.
