  Purpose

The purpose of this study is to evaluate whether MST-188 can reduce the duration of vaso-occlusive crisis (VOC) in subjects with sickle cell disease. The study will also evaluate whether MST-188 can reduce the frequency of rehospitalization of subjects due to a recurrence of VOC. Additionally, this study will compare the development of acute chest syndrome during VOC in subjects who receive MST-188 to those who do not receive MST-188.

MST-188 (lead product candidate)

MST-188 (purified poloxamer 188) is an investigational agent that has potential to reduce ischemic tissue injury and end-organ damage by restoring microvascular function, which is compromised in a wide range of serious and life-threatening diseases and conditions. We initially are developing MST-188 as a treatment for complications arising from sickle cell disease.

AIR001

 

This page contains Forward Looking Statements.*

AIR001 is a sodium nitrite solution for intermittent inhalation via nebulizer. 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 and cardiac output.

We are developing AIR001 for treatment of heart failure with preserved ejection fraction (HFpEF), a condition that affects millions in the U.S. and for which no proven therapeutic agent is available. Numerous lines of evidence suggest that HFpEF is a disease of NO deficiency. We are supporting two institution-sponsored Phase 2a studies in patients with HFpEF to evaluate acute hemodynamic effects of AIR001 and to evaluate its acute effects versus placebo on submaximal oxygen consumption and exercise hemodynamics.

How Does AIR001 Work?

 

AIR001 Inhalation Solution is sodium nitrite formulated with a phosphate buffer into an inhalation solution. Nitrite is a physiological signaling molecule with roles in intravascular endocrine nitric oxide (NO) production, hypoxic vasodilation, signaling, and cytoprotection after ischemia-reperfusion. Nitrite serves as the largest physiologic reservoir of NO and can be converted to NO independent of NO synthase (NOS) activity.

In experimental models, nitrite use demonstrated improved remodeling both in the pulmonary vasculature and right ventricle. Hemodynamic effects include venodilation with reductions in right atrial pressures, pulmonary and systemic vasodilation with reductions in pulmonary vascular resistance and left atrial pressures, and improved cardiac relaxation. In addition, recent clinical and nonclinical studies have demonstrated that nitrite can stimulate mitochondrial biogenesis and mitochondrial fusion and decrease mitochondrial oxygen consumption through a mechanism distinct from that of NO, which may have utility in treating heart failure.

AIR001 Clinical Data

 

We obtained the AIR001 program through our acquisition of Aires Pharmaceuticals, Inc. in February 2014. Prior to the acquisition, AIR001 had been tested in more than 120 healthy volunteers and patients with various forms of pulmonary hypertension in three Phase 1 studies and in one Phase 2 study in patients with pulmonary arterial hypertension. While the Phase 2 study was prematurely terminated due to Aires’ capital constraints prior to the acquisition, preliminary data from the study are positive, showing improvements in hemodynamic parameters and in exercise capacity from baseline. There were no treatment-related serious adverse events and methemoglobin levels remained normal (< 1.5%), which distinguishes AIR001 from safety concerns associated with intravenously-administered nitrite.

Data from these early clinical studies support continued clinical development of AIR001. Given the observed hemodynamic improvements of decreased right arterial pressure, decreased pulmonary capillary wedge (or left atrial pressure), as well as improvements in pulmonary vascular resistance and cardiac lusitropic effects, AIR001 may benefit patients with exercise impairment due to heart failure with preserved ejection fraction (HFpEF), for whom these are all desirable effects.

 


Potential Applications of AIR001

Hemodynamic improvements, improvements in pulmonary artery pressures, and cardiac lusitropic effects observed in earlier studies of AIR001 support AIR001’s potential to benefit patients with heart failure with preserved ejection fraction (HFpEF). We currently are pursuing clinical development of AIR001 for that patient population.
