About Infinity and Eganelisib

Infinity Pharmaceuticals, Inc. ("Infinity" or the "Company"), is a clinical-stage biotechnology company developing eganelisib (IPI-549), a potentially first-in-class, oral, immuno-oncology macrophage reprogramming therapeutic which addresses a fundamental biologic mechanism of immune suppression in cancer in multiple clinical studies. MARIO-275 is a randomized, controlled combination study of eganelisib combined with Opdivo® in I/O naïve urothelial cancer. MARIO-3 is the first eganelisib combination study in front-line advanced cancer patients and is evaluating eganelisib in combination with Tecentriq® and Abraxane® in front-line TNBC and in combination with Tecentriq and Avastin® in front-line RCC. In collaboration with Arcus Biosciences, Infinity is evaluating a checkpoint inhibitor-free, novel combination regimen of eganelisib plus etrumadenant (AB928, a dual adenosine receptor antagonist) plus Doxil® in advanced TNBC patients. In 2019, Infinity completed enrollment in MARIO-1, a Phase 1/1b study evaluating eganelisib as a monotherapy and in combination with Opdivo (nivolumab) in patients with advanced solid tumors including patients refractory to checkpoint inhibitor therapy. With these studies Infinity is evaluating eganelisib in the anti-PD-1 refractory, I/O-naïve, and front-line settings.
