QXL138AM is a Masked Immunocytokine (MIC) comprised of a masked interferon alpha (IFNa) fused to an antibody that targets the CD138 protein on the surface of the tumor cells. Once QXL138AM binds to the tumor cell, proteases on the cell surface cleave the mask off of the IFNa allowing it to bind its receptor. Activation of the IFNa receptor complex induces direct killing of tumor cells in addition to activating innate and adaptive anti-tumor immunity. Preclinical data has demonstrated significant anti-tumor efficacy across more than 10 tumor types including multiple myeloma where complete regression at doses as low as 0.1 mg/kg have been observed. Nammi has secured Orphan Drug Designation in multiple myeloma from the FDA on the strength of this data.

"While the multiple myeloma field has greatly benefitted from development of bispecific and cell therapies, there unfortunately remains a significant need for novel therapeutics such as QXL138AM.", said David Stover, Ph.D., President and CEO of Nammi. "We are very excited to partner with MIF and the Multiple Myeloma Research Foundation (MMRF) and leverage their expertise to accelerate the development of QXL138AM. Together, we will work to realize the potential of this therapy to improve the lives of patients with multiple myeloma."

With this investment by MIF, Nammi anticipates the $30M Series B financing round will be fully subscribed upon its closing when the first patient has been treated with QXL138AM.

"Nammi’s innovative technology and its application in multiple myeloma is an important step for the myeloma patient community," said Michael Andreini, President and CEO of the Multiple Myeloma Research Foundation. "Advancing new therapeutic options for patients is the most critical task-at-hand, so we are thrilled to support Nammi’s Phase-1 trial to learn the potential of this exciting new immunotherapy approach."
