Biopharma, Inc.

development,” said Lisa N. Drakeman, Ph.D., Chief Executive Officer.  “This is

“Zanolimumab has promise for treatment of patients with T cell cancers, and     
potential in other cancer types for which existing therapies are inadequate”,   
said Gardiner F.H. Smith, Chief Executive Officer of TenX Biopharma. “We are    
building a pipeline of new medicines for high unmet need, with a focus on the   
patient through business efficiency.” 

Asher Nathan, Managing Partner of Zoticon Bioventures, and lead investor in     
TenX, said “TenX and zanolimumab represent the fourth late stage drug funding   
which we've led in the past two years.  I'm delighted that this important       
product will be available in the future, and look forward to the management team
at TenX continuing to build value with novel cancer therapeutics.”
