Mast Therapeutics
 We are a publicly traded biopharmaceutical company headquartered in San Diego, California.

We are leveraging the MAST (Molecular Adhesion and Sealant Technology) platform, derived from over two decades of clinical, nonclinical and manufacturing experience with purified and non-purified poloxamers, to develop MST-188, our lead product candidate, for serious or life-threatening diseases with significant unmet needs.  Webcast from Cowen Healthcare Conference 03/03/14  Piper Jaffray Healthcare Conference 12/03/13 : 30 minute audio presentation by CEO B.

The purpose of this study is to evaluate whether ANX-188 can reduce the duration of vaso-occlusive crisis (VOC) in subjects with sickle cell disease. The study will also evaluate whether ANX-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 ANX-188 to those who do not receive ANX-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.
