Hillstream BioPharma, Inc. (Nasdaq: HILS) ("Hillstream" or the "Company"), a biotechnology company developing a portfolio of therapeutic candidates targeting drug resistant and devastating cancers, announced pharmacokinetic (PK) data of HSB-1216 supportive of its development strategy and pre-clinical data. These data suggest Quatramer protects HSB-1216 from metabolic degradation until its release at the tumor site and is consistent with the promising efficacy data demonstrating effective reduction of tumor growth in pre-clinical studies.

The preliminary safety and PK of HSB-1216 was evaluated in IND-enabling studies using rats and dogs showing the Quatramer bound HSB-1216 throughout a 48-hour exposure period prevented degradation in the in systemic circulation until its targeted release at the tumor site.

“We are greatly encouraged by these early PK data which are both supportive of our overall development strategy as well as our earlier pre-clinical data,” said Randy Milby, Hillstream’s Chief Executive Officer.
