• Purple said that it has achieved a commercially viable yield for IM1240, positioning the program competitively for future development.
• The company now plans to make an Investigational New Drug (IND) submission to the U.S. Food and Drug Administration in 2026, paving the way for its first-in-human clinical trials.
  

NASDAQ-listed shares of Purple Biotech Ltd. (PPBT) soared 92% on Wednesday morning after the company achieved a manufacturing milestone for its experimental cancer drug IM1240.

The company said that it has achieved a commercially viable yield for IM1240, positioning the program competitively for future development.

IM1240 is a tri-specific antibody from the CAPTN-3 preclinical platform targeting the antigen 5T4, which is expressed in a variety of solid tumors and is associated with advanced disease, increased invasiveness, and poor clinical outcomes. The company now plans to make an Investigational New Drug (IND) submission to the U.S. Food and Drug Administration in 2026, paving the way for its first-in-human clinical trials.

“Drawing on my decades of experience in antibody manufacturing, producing a tri-specific protein such as IM1240 at high yield and purity was perceived as a significant challenge-one that I’m pleased to have successfully mastered.” 
Michael Schickler, Head of Clinical and Regulatory Affairs, Purple Biotech

The company now has until April 14, 2026, to regain compliance with the minimum bid price requirement.
