XNK Therapeutics receives US orphan drug status

November 4, 2020

XNK Therapeutics AB (“XNK”) today announced it has received Orphan Drug Designation (ODD) from the U.S. Food and Drug Administration (FDA) for its leading investigational drug candidate in the treatment of multiple myeloma (MM).

Receiving ODD status from the FDA for the treatment of multiple myeloma is a critical next step for the development of XNK’s leading investigational drug candidate. XNK has already received ODD status in the EU.

“Obtaining an ODD by the FDA is a significant milestone for XNK and our goal of taking the present drug candidate to the next level,” said Johan Liwing, CEO of XNK Therapeutics. “This is the starting point for us to expand clinical development into the most important market globally for cancer treatment.”

XNK has already completed its first-in-human Phase I/II clinical trial (ACP-001) in multiple myeloma at the Karolinska University Hospital in Stockholm, Sweden, showing a very good safety profile, and promising efficacy data. The company is continuing the clinical development in multiple myeloma in Europe and plans to initiate a Phase II clinical trial in the near future.

About Our Therapy
The leading drug candidate from XNK Therapeutics’ technology platform was previously clinically tested in a first-in-human Phase I/II clinical trial (ACP-001). The study was performed at the Karolinska University Hospital, Stockholm, Sweden in a setting of consolidation treatment following high dose stem cell transplantation in patients newly diagnosed with multiple myeloma. The study was an open, single-arm, triple escalating dose/patient clinical trial with the primary objective of studying the product’s safety and tolerability. In the study, the therapy showed a very good safety profile, and promising efficacy data. XNK Therapeutics is continuing its clinical development in multiple myeloma and plans to initiate a Phase II clinical trial in the near future.

About multiple myeloma
Multiple myeloma, the company’s first target, is the third most frequent hematological malignancy worldwide. Multiple myeloma treatment has improved over the last two decades with the development and introduction of new agents leading to more effective treatments. Still, it remains a fatal disease in the majority of cases.
