First patient cells collected in XNK's preclinical bladder cancer study

HUDDINGE, Sweden, Dec. 15, 2022 /PRNewswire/ -- XNK Therapeutics AB ("XNK") today announced that the first patient has donated cells in the recently initiated preclinical evaluation of the autologous NK cell product XNK03 in locally advanced or metastatic urothelial cancer. The study is performed in collaboration with Anders Ullén's research group at the Karolinska University Hospital, Stockholm, Sweden.

This is the company's first solid tumor indication and complements the ongoing Phase II clinical study in multiple myeloma (MM) and the preclinical proof-of-concept study in acute myeloid leukemia (AML) using patient samples from The University of Texas MD Anderson Cancer Center. Between 10-15 patients with advanced urothelial cancer will be enrolled in the study and will donate cells before and after chemotherapy treatment.

"The possibility to confirm that our proprietary technology can successfully expand and activate NK cells from the exact patient population we intend to treat in the future is an important step towards a clinical study," said Johan Liwing, CEO of XNK Therapeutics. "We are enthusiastic about this joint effort with the Karolinska University Hospital to seek out more effective treatments in a patient population with high and unmet medical need."

Urothelial cancer is the most common form of bladder cancer. More than 80,000 new cases of bladder cancer are expected in the US in 2022 alone, according to the American Cancer Society.

About Bladder Cancer

According to the World Health Organization over 570,000 new cases of bladder cancer was diagnosed in 2020 globally. It is the 4^th most common form of cancer in men and the American Cancer Society estimates that bladder cancer will cause over 17,000 deaths in 2022 in US alone. It affects mainly older people with 90% of patients being diagnosed at an age above 55 years. In locally advanced urothelial cancer, which constitutes about 30% of bladder cancers, the 5-year survival rate is below 40% and current treatments may include removal of the entire bladder, radiation, chemotherapy and checkpoint inhibitors. For metastatic disease the 5-year survival rate is limited to approximately 6% and current standard systemic treatments include chemotherapy, immunotherapy and antibody-drug conjugates.
