Inspyr Therapeutics announced the initiation of development programs focused on Mipsagargin combination therapies. To evaluate the potential of Mipsagargin in combination with Nexavar®, Inspyr plans to conduct a preclinical study in liver PDX tumor models that express PSMA, the target of Mipsagargin. The tumor models selected express different levels of PSMA, including one that is resistant to Nexavar®. The Company expects to share initial results of this study in the second quarter of 2017. Concurrently, the Company is finalizing the design of a clinical study to examine the potential benefits of Mipsagargin in combination with Nexavar® in patients with advanced hepatocellular carcinoma (HCC), or liver cancer.
