SINGAPORE I January 03, 2018 I ASLAN Pharmaceuticals (ASLAN, 6497.TT), a clinical-stage biopharmaceutical company targeting cancers that are both highly prevalent in Asia and orphan indications in the United States and Europe, today announced that Array BioPharma Inc (Array) has granted ASLAN full global rights to develop, manufacture and commercialise varlitinib. The new licensing agreement replaces the prior licensing agreement signed in 2011 to develop and sublicense varlitinib, which did not grant commercial rights to ASLAN.

Dr Carl Firth, Chief Executive Officer of ASLAN Pharmaceuticals, said:Acquiring full global commercial rights to varlitinib is a significant positive move for ASLAN. Varlitinib has demonstrated strong efficacy in the studies that we have conducted since signing the original licensing agreement with Array, in biliary tract, gastric, breast and colorectal cancer. Based on this data, we want to take the drug to market and commercialise it ourselves in certain geographies, which was not contemplated under the original agreement. The new agreement allows us to retain much more downstream value from our own commercial and future partnering activities.”

Under the terms of the original agreement signed on 12 July 2011, ASLAN was responsible for the development of varlitinib through to proof-of-concept and the identification of a partner to complete phase 3 development and commercialisation. Array was eligible to receive 50% of all varlitinib revenues, including proceeds from outlicensing agreements. 

The terms of the new agreement grant ASLAN exclusive global rights to commercialise and sublicense varlitinib. ASLAN will make an upfront payment of US$12 million to Array on signature and a further payment of up to US$12 million within the next twelve months, together with up to US$30 million of development and US$75 million of commercial milestones, as well as tiered low double-digit royalties as a percentage of net sales of varlitinib

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, HER3 and HER4. These receptors can be mutated or overexpressed in many tumors, which can cause excessive proliferative activity and uncontrolled growth. Therefore, by inhibiting the activation of the HER receptors, varlitinib could inhibit proliferation and control tumor growth. Varlitinib is currently being studied in gastric, biliary tract, breast and colorectal cancers.  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.
