About PRTX007

PRTX007 is Primmune’s lead TherAjuvant™, a combination of therapeutic and adjuvant mechanisms of action. PRTX007 is designed to provide immediate benefit to patients through controlled stimulation of the innate immune response while also potentiating long-term effective innate and adaptive immune responses. PRTX007 uniquely engages TLR7 and targeted immune cells without increasing levels of proinflammatory factors like IL-6, TNFα and IL-1β via NF-κB. TherAjuvants™ differ from other small molecule approaches in that they engage the patient’s immune system rather than acting at virally encoded targets or endogenous tumor cell proteins. PRTX007 is being rapidly advanced towards clinical trials for viral diseases and cancer.
