|We are a clinical stage biopharmaceutical company focused on identifying, developing, and commercializing product candidates that modulate the activity of key regulatory proteins involved in the biology of mitochondrial function, oxidative stress, and inflammation to address the unmet medical needs of patients with a variety of serious or life-threatening diseases. Our lead product candidates, bardoxolone methyl and omaveloxolone, are members of a class of small molecules called antioxidant inflammation modulators, or AIMs. Bardoxolone methyl is in Phase 3 clinical development for the treatment of pulmonary arterial hypertension, or PAH, associated with connective tissue disease, or CTD-PAH, and Phase 2 clinical development for the treatment of idiopathic pulmonary arterial hypertension, or I-PAH, and pulmonary hypertension due to interstitial lung disease, or PH-ILD, each of which are subsets of pulmonary hypertension. Initial data for PAH patients in our Phase 2 trial have been presented publicly at the CHEST meeting in October 2015. In addition, we have completed an interaction with the U.S. Food and Drug Administration, or FDA, on these initial data, and the FDA concurred with our plan to initiate a Phase 3 trial in patients with CTD-PAH. We have initiated activity on our Phase 3 trial in CTD-PAH and plan to begin enrolling patients in the second half of 2016. Omaveloxolone is in Phase 2 clinical development for the treatment of multiple diseases, including Friedreich’s ataxia, mitochondrial myopathies and metastatic melanoma. Beyond our lead product candidates, we have several promising preclinical programs. We believe that our product candidates and preclinical programs have the potential to improve clinical outcomes in numerous underserved patient populations.
