Helix BioPharma Corp. (TSX:HBP, OTC PINK:HBPCD, FRANKFURT:HBP0) announced the appointments of Helen Middleton as General Counsel and David Browning as Vice President of Clinical Operations, strengthening its executive leadership as the company prepares for a planned U.S. securities exchange listing and advances L-DOS47 into a Phase IB/Randomized Phase II study for first-line non-small cell lung cancer (NSCLC).
“The next stage of Helix’s evolution demands a different kind of company than the one we were building two years ago,” said Thomas Mehrling, MD, PhD, Chief Executive Officer. “As we prepare for our planned U.S. securities exchange listing and advance L-DOS47 into its next stage of clinical development, we are deliberately strengthening every part of the organization. From our legal and governance framework to our clinical execution capabilities, we are building the leadership team required to support the next phase of Helix’s growth.”
With the preparation of a base shelf prospectus underway and auditor review of second-quarter financials completed, the company is executing on a clear capital markets roadmap. “Helen and David are exceptional additions to Helix. Helen brings decades of experience navigating the legal and governance challenges faced by growing life sciences companies, while David has successfully led complex global oncology programs from planning through execution. Together, they significantly strengthen our ability to deliver on our clinical, corporate and capital markets objectives,” Mehrling added.
