Under terms of the agreement, Stiefel has also received a conditional right to acquire further exclusive rights to develop and commercialize WBI-1001 in China, Taiwan, Macao and Hong Kong, collectively. Upon satisfaction of certain conditions, Welichem will receive an additional payment of CAD$15million.
“I’m delighted to build upon Stiefel’s clinical pipeline of novel dermatology assets with the acquisition of WBI-1001,” said Barbara White, Senior Vice President and Head of Research and Development, Stiefel. “We have a strong commitment to patients with skin conditions and are excited to undertake development of this innovative agent.”
WBI-1001 is a novel, non-steroidal, topical anti-inflammatory new chemical entity (NCE) that has demonstrated efficacy and safety in Ph1 and Ph2 clinical trials for the treatment of mild to moderate psoriasis[i] and moderate to severe atopic dermatitis[ii] for up to 12 weeks as a single therapy. However, Stiefel notes that WBI-1001 is still in development and there are still risks and uncertainties to which the NCE is subject.
