Polynoma LLC, a U.S. oncology-focused biotechnology company within Hong Kong-based CK Life Sciences Int’l., (Holdings) Inc., today announced the expansion of the Company’s senior leadership team with the appointments of Sara Zaknoen, MD, Chief Medical Officer, Andrew Buckland, Chief Financial Officer and Patrick Mallon, Chief Operating Officer. All three have extensive backgrounds in the life sciences industry and proven track records in development and commercialization.

“Sara, Andrew and Pat each have proven experience and track records that will be invaluable to Polynoma, and we are extremely excited to announce their appointments and the expansion of our management team,” said John Chiplin, PhD, Chief Executive Officer. “This is an exciting stage in Polynoma’s growth. We are continuing to enroll patients into our global Phase III clinical trial of POL 103A, our lead cancer vaccine candidate. These patients have Stage IIb, IIc & III melanoma, for which there currently are no adequate therapies and therefore a substantial unmet need.”

Dr. Zaknoen earned a BS degree in Chemistry and Biology from Valparaiso University, and an MD degree from the Indiana University School of Medicine.

He has served as Chief Financial Officer of Advanced Tissue Sciences and most recently as the Chief Financial Officer of PURE Bioscience – a company that he transitioned to a NASDAQ-listed company. He also held senior financial management positions at United Parcel Service and Bristol-Myers Squibb. Mr. Buckland earned a BA degree (with Honors) from the University of the West of England, and an MBA degree from the University of California, Irvine.

Mr. Mallon has broad-based C-level experience in the pharmaceutical, life sciences and medical device industries for both public and private companies, including Roche, Gen-Probe, Agouron Pharmaceuticals, and most recently at Genpathway, where he served as CEO.
