Kintor Pharmaceutical Limited Announces 2020 Business Progress and Annual Results

SUZHOU,China,March 26,2021 -- Kintor Pharmaceutical Limited (stock code 9939.HK,"Kintor Pharmaceutical" or the "Company"),a clinical-stage biotechnology company developing small molecule and biological therapeutics,recently announced its business highlights and financial results for the year ended December 31,2020.

Dr. Youzhi Tong,co-founder,chairman,and CEO of Kintor Pharmaceutical,said,"In 2020,despite the global COVID-19 pandemic and subsequent public health crisis,theKintor teamovercame numerous challenges and continued making breakthroughs in research and development,and progress in clinical operations and commercial collaborations. On May 22,the Company was officially listed on the main board of the Hong Kong Stock Exchange,raising approximately US$240 million,which will support the Company's long-term goals in developing and commercializing important therapeutics for unmet medical needs.

The Company's new investigational drug,proxalutamide,has expanded its indication to COVID-19. Clinical research has found that it may be an important tool in treating COVID-19 patients with mild,moderate,severe,and critical symptoms. In an investigator-initiated clinical trial in Brazil,results announced showed that among patients treated with proxalutamide the hospitalization rate of male patients with mild or moderate symptoms was reduced by 100%,while that of female patients was reduced by 90%; the mortality rate of severely-ill patients was reduced by 92%,cutting the length of stay by 9 days.

In addition,the Company collected positive data in a Taiwan-based Phase II clinical trial of the combination therapy of ALK-1 monoclonal antibody and nivolumab to treat metastatic hepatocellular carcinoma (HCC). The trial results showed an objective response rate (ORR) of 40%. The Phase II clinical trial of the combination therapy of ALK-1 monoclonal antibody and nivolumab for the second line therapy of HCC has been approved by the U.S. Food and Drug Administration(FDA),and we are in the process of recruiting patients.

In 2020,the Company established partnerships with six companies. We entered into an exclusive license agreement with the American firm,Gensun for the development and commercialization of the dual-target antibody PD-L1/TGF-β in Greater China. We will be collaborating in the field of monoclonal antibody and bispecific antibody of biological medicine. We also reached a collaboration agreement with Alphamab Oncology to jointly promote the clinical research of ALK-1monoclonal antibody GT90001 combined with recombinant humanized PD-L1/CTLA-4 bispecific antibody KN046 for the treatment of hepatocellular carcinoma andother tumors globally. In August,Kintor Pharmaceutical opened a Good Manufacturing Plant (GMP).

In the face of the COVID-19 pandemic,we at Kintor Pharmaceutical,are deeply aware of the great responsibilities we shoulder. We are gratified to see that proxalutamide is showing great promise in clinical trials for the treatment of COVID-19. The Kintor team has worked on proxalutamide for more than ten years. At the same time,I am pleased that we have received this Phase III clinical trial approval from the FDA. This has been the first Phase III clinical trial approval from the FDA since Kintor's 2009 founding.

Looking ahead to 2021,Kintor Pharmaceutical will continue its efforts to advance the developmentand commercialization of proxalutamide,as a safe and effective treatment for COVID-19.

In the future,the Company will accelerate the global clinical development of our existing product pipeline,continue to strengthen international and domestic partnerships,and fulfill our mission of "focusing on the research,development and commercialization of a large number of indications with unmet clinical needs." We will continue to work on benefiting more patients and creating long-term value for shareholders."
