- K-MASTER, Korea’s leading precision medicine research group, to conduct phase 1b/2 umbrella study testing varlitinib as a second-line treatment in HER1/HER2 co-expressing advanced or metastatic gastric cancer patients
SINGAPORE, May 10, 2019 (GLOBE NEWSWIRE) -- ASLAN Pharmaceuticals (Nasdaq:ASLN, TPEx:6497), a clinical-stage oncology and immunology focused biopharma company, today announced that it has signed an agreement with the Korean Cancer Diagnosis & Treatment Enterprise (K-MASTER) to investigate varlitinib in a phase 1b/2 multi-centre umbrella study to evaluate the safety and efficacy of varlitinib in combination with weekly paclitaxel as a second-line treatment in HER1/HER2 co-expressing advanced or metastatic gastric cancer patients.
K-MASTER, operated by Korea University, is funded by the South Korean government to support three key goals: genomic sequencing of cancers, clinical trials for South Korean cancer patients, and the development of a cancer genomics database. K-MASTER is already involved in 16 clinical trials, which include testing new drugs targeted at specific cancer mutations.
The two-part, phase 1b/2, open label, multi-centre study will recruit approximately 400 patients, divided between four experimental arms and a common control arm based on biomarker profiling. Patients that are HER1/HER2 co-expressing will receive varlitinib in combination with weekly paclitaxel. Other arms will test PD1 and PI3K-beta inhibitors. The study, led by Professor Sun Young Rha of the Yonsei Cancer Center, will be conducted in up to 10 sites in South Korea.
The primary objective of the phase 1b study is to determine the maximum tolerated dose and the recommended phase 2 dose of the varlitinib and paclitaxel combination. The phase 2 part of the study will evaluate the treatment effect of the varlitinib and paclitaxel combination on progression free survival (PFS) in subjects with HER1 and HER2 co-expression in advanced or metastatic gastric cancer. ASLAN has previously conducted studies of varlitinib in first-line gastric cancer patients where there was a trend towards a clinical benefit in patients treated with varlitinib.
Dr Chih-Yi Hsieh, Chief Medical Officer of ASLAN Pharmaceuticals, said: “The current prognosis of patients with advanced gastric cancer remains poor, even in countries like Korea where screening is widely performed. There is a clear need for new therapeutic agents to improve treatment outcomes and the survival of patients. Varlitinib is a potent inhibitor of HER1 and HER2, which are often over-expressed in gastric cancer, and we are delighted that it has been identified by the prestigious K-MASTER group as a promising new treatment for second-line gastric cancer in this ground breaking study.”
Gastric cancer is the fifth most common cancer worldwide. Gastric cancer is especially prevalent in Asia, with Asia making up 74.5% of gastric cancer incidences worldwide1. Korea has the highest age standardised rates in the world2.

About varlitinib (ASLAN001)
Varlitinib (ASLAN001) is a highly potent, oral, reversible, small molecule pan-HER inhibitor that targets the human epidermal growth factor receptors HER1, HER2 and HER4. These receptors can be mutated or overexpressed in many tumours, which can cause excessive proliferative activity and uncontrolled growth. Therefore, by inhibiting the activation of the HER receptors, varlitinib could inhibit proliferation and control tumour growth. Varlitinib has been granted orphan drug designation in the United States for gastric cancer and cholangiocarcinoma, a sub-type of biliary tract cancer, and was awarded orphan drug designation for the treatment of biliary tract cancer by the Ministry of Food and Drug Safety in South Korea.
