Our competitive analysis shows 9-ING-41 to be Best in Class. Ongoing research has demonstrated significant anti-tumor activity in many in vivo models of difficult to treat cancers, including cancers of the brain, pancreas, lung, and breast. We are unaware of any published research demonstrating the kind of efficacy in treatment-resistant glioblastoma that we have been able to achieve with 9-ING-41. Importantly, the toxicity and pharmacokinetic profiles of the drug candidate are quite attractive. | $6.5M / Series B / Nov 12, 2019 | |

Lung Therapeutics
|
Lung Therapeutics is a pharmaceutical company targeting niche, orphan drug indications for lung injury and disease, with an emphasis on fibrosis. Current efforts are focused on a severe complication of pneumonia, called loculated pleural effusion, a debilitating condition where fluid has built up in the chest cavity surrounding the lungs andfibrinous scar tissue in the pleural cavity blocks fluid drainage. Their first product, LTI-01 (single chain urokinase plasminogen activator, or scuPA), is being studied for safe clearance of fibrinous scar tissue in patients with loculated pleural effusion. By clearing the fibrinous buildup pharmaceutically, the clinical pathway for these patients is significantly improved, enabling simple draining of pleural fluid without surgery. Their longer-term efforts will target improvement of clinical pathways for Acute Lung Injury, Idiopathic Pulmonary Fibrosis and other disease conditions. | $36M / Series C / Jun 04, 2019 | |
