Prokarium Achieves Milestone with First Patient Dosing in PARADIGM-1 Non-Muscle Invasive Bladder Cancer Clinical Trial

London, UK – February 7, 2024 –  Prokarium, a clinical-stage biopharmaceutical company bioengineering Living Cures through cutting-edge synthetic biology, today announces the dosing of the first patient in their PARADIGM-1 Phase I/Ib clinical trial in non-muscle invasive bladder cancer (NMIBC) patients (NCT06181266).

The study is being conducted at multiple clinical sites across the United States and will initially evaluate the safety of a single intravesical administration of their investigational immunotherapy, ZH9, in NMIBC patients. The study will further investigate and characterize clinical efficacy of the ZH9 treatment regimen in pre-planned expansion cohorts under the same IND.

“Dosing our first patient in the clinical trial is an exciting milestone,” said Dr Josefin-Beate (Josi) Holz, CMO of Prokarium. “It translates our scientific promises into practical advancements, as we strive to transform the treatment paradigm for patients with NMIBC.”

Dr Daniel Zainfeld, Urology San Antonio commented, “We are excited to have dosed our first patient in Prokarium’s PARADIGM-1 study. The trial provides us the opportunity to explore an innovative treatment approach for our NMIBC patients who are facing significant gaps in available effective treatment options.”

Kristen Albright, CEO of Prokarium, remarked, “We are grateful to the patients and urologists involved in the PARADIGM-1 clinical trial. This achievement represents a pivotal moment for Prokarium as we introduce Living Cures, a novel class of immunotherapies built with synthetic biology.”
