Immunomedics Announces Agreement with University of Wisconsin Carbone Cancer Center to Expand Sacituzumab Govitecan (IMMU-132) into Prostate Cancer

Immunomedics to Fund Phase 2 Study Sponsored by the University of Wisconsin to Enable Further Investigation of Sacituzumab Govitecan in the Treatment of Patients with Castration-Resistant Prostate Cancer (CRPC)

Partnership Underscores Immunomedics’ Strategy to Broaden Development of Sacituzumab Govitecan Beyond Metastatic Triple-Negative Breast Cancer (mTNBC) and Advanced Urothelial Cancer (UC) and Meet High Unmet Medical Need in Patients with Advanced CRPC

MORRIS PLAINS, N.J., Jan. 11, 2018 (GLOBE NEWSWIRE) -- Immunomedics, Inc., (NASDAQ:IMMU) (“Immunomedics” or the “Company”) today announced a collaboration with the Carbone Cancer Center at the University of Wisconsin, through Immunomedics entering an agreement with The Prostate Cancer Clinical Trials Consortium (PCCTC), to investigate Immunomedics’ lead antibody-drug conjugate (ADC) product candidate, sacituzumab govitecan, in an investigator-sponsored Phase 2 trial in patients with advanced castration-resistant prostate cancer (CRPC).

“The therapeutic landscape for men with CRPC has become limited. With the earlier use of agents such as abiraterone acetate and docetaxel, as well as cross resistance to other FDA approved options, including enzalutamide or cabazitaxel, there is a critical need for new therapeutic agents with unique mechanisms of action,” stated Joshua M. Lang, MD, Assistant Professor, Division of Hematology/Oncology, University of Wisconsin Carbone Cancer Center, Madison, WI, and the lead investigator of the Phase 2 study. “Sacituzumab govitecan is a first-in-class ADC that targets a molecule known as Trop-2 and has shown clinical activity in patients with mTNBC and advanced UC.” 

Dr. Lang has previously demonstrated high Trop-2 expression on many types of resistant prostate cancer. In addition to the Phase 2 trial, Dr. Lang will also be leading a broad translational program integrated into the clinical study to further validate the expression and importance of Trop-2 as a therapeutic target in various stages of prostate cancer. A recent $1 million Challenge Award to conduct biomarker work from the Prostate Cancer Foundation will support this comprehensive examination of tumor samples for mutations and gene expression profiles in order to identify molecular pathways associated with Trop-2 expression and resistance development at various clinical disease states.

Through its relationship with PCCTC, Immunomedics is collaborating with the University of Wisconsin to expand these efforts into an investigator-sponsored Phase 2 clinical trial to assess whether targeting Trop-2 with sacituzumab govitecan is promising in prostate cancer patients. Approximately 55-60 male patients with CRPC progressing on enzalutamide or abiraterone, objectively or based on prostate-specific antigen level, in either hormone naïve or CRPC settings will be enrolled into the multicenter study.

“At Immunomedics, we continue to follow our strategic plan to become a fully-integrated biopharmaceutical company, and the exciting partnership with the Carbone Cancer Center is another important step in doing so,” commented Usama Malik, Chief Business Officer of Immunomedics. “We have developed a very robust and multi-faceted clinical development plan for sacituzumab govitecan, and exploring the efficacy and safety of our lead asset in indications beyond mTNBC and advanced UC is a core component of this strategy. Most importantly, advanced CRPC represents an area of high unmet need where we have an opportunity to change the outcome of patients with very limited treatment options.”
