LSKB Announces its Clinical Initiative to Study the Safety and Efficacy of Combining Apatinib with Immunotherapy

SALT LAKE CITY, USA, December 10, 2017 — LSK BioPharma (LSKB, Company) announced a new initiative to study the safety and efficacy of cancer therapies combining apatinib with immunotherapy. The first clinical study, designated LSK-AM107, will take place at the Cancer Center of Southern California in Santa Monica, California under the direction of Sant P. Chawla, MD, FRACP. The Company has finalized a clinical trial agreement with Dr. Chawla’s institution and will conduct a Site Initiation Visit (SIV) on December 18th, 2017. LSKB expects to recruit patients soon after the SIV.

LSK-AM107, titled  “An Open-labeled Phase 1 Study to Evaluate the Safety and Tolerability of Apatinib with Nivolumab in Patients with Unresectable or Metastatic Cancer” is expected to enroll up to 30 patients and will assess the safety of the combination as well as preliminary efficacy from tumor response, progression-free, and overall survival.

Many cancers manipulate normal immune regulatory pathways (immune checkpoints) that allow them to hide from the immune system, shielding tumors from attack by the immune system. Cancer immunotherapy with checkpoint inhibitors such as nivolumab help restore the body’s natural antitumor immune response.

Preclinical research demonstrated the combination of apatinib, an angiogenesis inhibitor, with checkpoint inhibition is highly synergistic in limiting tumor growth. This synergy can be attributed to apatinib’s modulation of the tumor environment through upregulation of checkpoint target ligands, increasing of tumor-infiltrating lymphocytes, and decreasing of tumor immunosuppression.

LSKB is also planning to support an Investigator Initiated Trial (IIT) at a US institution studying the safety and efficacy of apatinib in combination with pembrolizumab. This study is expected to enroll its first patients in early 2018.

About Apatinib Apatinib is the first successful small-molecule angiogenesis inhibitor in gastric cancer. Apatinib acts by inhibiting angiogenesis, a critical process in cancer growth and proliferation. Specifically, apatinib selectively inhibits VEGFR-2 which mediates the primary pathway for tumor-mediated angiogenesis. It was approved in China (advanced gastric cancer, Dec 2014) where it is marketed by the Chinese-territory license-holder Jiangsu Hengrui Medicine Co., Ltd. LSK BioPharma, which holds the global rights (ex-China), has partnered development and marketing in South Korea with Bukwang Pharmaceutical Co., Ltd. The Company is currently conducting a global (12 countries including US, Japan, Korea, Italy, Germany, and Russia) Phase 3 clinical trial of apatinib in advanced or metastatic gastric cancer patients. Apatinib has been clinically tested in over 1,000 patients worldwide and has demonstrated efficacy in numerous cancers including gastric cancer, CRC, HCC, NSCLC, esophageal cancer, thyroid cancer, mesothelioma, and neuroendocrine tumors. It has also shown potential to significantly improve outcomes in combination with chemotherapeutics and immunotherapy, as well as for maintenance therapy. LSKB has received notification designating apatinib as an orphan medicinal product for the treatment of gastric cancer from the European Commission in the European Union, the US FDA, as well as the MFDS in South Korea.
