SAN DIEGO, Oct. 17, 2016

SAN DIEGO, Oct. 17, 2016 /PRNewswire/ -- Mast Therapeutics, Inc. (NYSE MKT: MSTX) today announced that its wholly-owned subsidiary, Aires Pharmaceuticals, Inc., has entered into a collaborative agreement with Philips Respironics, Inc., the sleep and respiratory care business of Royal Philips (NYSE: PHG, AEX: PHIA) related to the supply of Philips' I-neb® Adaptive Aersol Delivery (AAD™) devices and related consumables for the nebulized delivery of the Company's lead product candidate, AIR001, a sodium nitrite solution for intermittent inhalation. The I-neb® handheld AAD™ system is a small, portable and virtually silent vibrating mesh technology nebulizer system designed to deliver more precise, reproducible doses of medication faster than conventional jet or ultrasonic nebulizers. 

"As we announced last month, we are accelerating activities related to our AIR001 program with support for ongoing, investigator-sponsored Phase 2 clinical studies of AIR001 being conducted at three separate prestigious research institutions," said Brian M. Culley, Chief Executive Officer of Mast. "As part of this commitment, we are pleased to be working with Philips, a recognized global leader in the development of aerosol delivery devices and a leading provider of innovative solutions for the global respiratory market. Our agreement has been extended to include not only two of the Phase 2 studies of AIR001 currently underway, but also future clinical studies and will remain in place until 2020 or sooner, if replaced with a commercial supply agreement." 

About AIR001

AIR001 is a sodium nitrite solution for intermittent inhalation via nebulization. Nitrite is a direct vasodilator and can be recycled in vivo to form nitric oxide (NO) independent of the classical NO synthase (NOS) pathway. Nitrite mediated NO formation has several beneficial effects, including dilation of blood vessels and reduction of inflammation and undesirable cell growth. Generation of NO from sodium nitrite is not dependent upon endothelial function and is enhanced in the setting of tissue hypoxia and acidosis, conditions in which NOS activity typically is depressed. In early clinical studies, AIR001 demonstrated positive hemodynamic effects with reductions observed in right atrial pressure and pulmonary capillary wedge pressure, as well as improvements in mean pulmonary artery pressures, cardiac output, and exercise tolerance as measured by six-minute walk distance. In a randomized, double-blind, placebo-controlled Phase 2a study of AIR001 in patients with HFpEF (n=26), the AIR001 treatment group showed a statistically significant decrease in pulmonary capillary wedge pressure during exercise compared to the control group and AIR001 was generally well-tolerated.
