Management Comments

Chief executive officer and chairman of CTMX, Sean McCarthy, commented that they are happy to publish the initial results from its Phase-II study of CX-2029. The response rate from recent data in heavily-pretreated sqNSCLC patients is trending with their stated target of 20%. They are also motivated by the low discontinuation rate due to unfavorable events. These results affirm their earlier Phase-I observations. The company will continue to collaborate with its partner, AbbVie. They look forward to finishing the expansion phase of the CX-2029 program and delivering further updates by 2022, Mr. Sean added.
