Molgradex is an inhaled formulation of recombinant human GM-CSF that is being developed for the treatment of autoimmune pulmonary alveolar proteinosis, or PAP, a rare lung disease characterized by the build-up of lung surfactant in the alveoli, or air sacs, of the lungs.
PAP is estimated to have a prevalence of approximately 2,500 patients in the United States. The disease process underlying PAP involves an autoimmune response against a naturally occurring protein, GM-CSF, suppressing the stimulating activity of GM-CSF on lung macrophages which function to clear excess surfactant from the alveoli.
Molgradex has been granted Orphan Drug Designation for the treatment of PAP in the United States and the European Union. The Orphan Drug Designation makes Molgradex eligible for seven years of exclusivity from approval in the United States, and ten years of exclusivity in the European Union.
AeroVanc is an inhaled formulation of vancomycin, and is being developed for the treatment of persistent methicillin-resistant Staphylococcus aureus, or MRSA, lung infection in cystic fibrosis, or CF, patients.
CF is a genetic disease that involves sticky mucus buildup in the lungs, persistent lung infections and permanent and progressive respiratory disability. There are approximately 30,000 patients affected by CF in the United States, and MRSA infection has become increasingly common in these patients, with a prevalence of approximately 26 %. Persistent MRSA infection in CF patients is associated with increased use of intravenous, or IV, antibiotics, increased hospitalizations, a faster decline of lung function, as well as shortened life-expectancy. Due to the lung pathology associated with CF, persistent MRSA lung infection is difficult to eradicate or manage using oral or IV antibiotics, there is no standard of care to manage this condition and there are no approved inhaled antibiotics addressing MRSA lung infection.
In a randomized, double-blind, placebo-controlled Phase 2 study in CF patients with persistent MRSA infection, AeroVanc reduced MRSA density in sputum, and showed encouraging trends of improvement in lung function, and respiratory symptoms, as well as prolongation of the time to use of other antibiotics, with best responses in subjects under 21 years of age.
AeroVanc has been granted Orphan Drug Designation and Qualified Infectious Disease Product, or QIDP, status for the treatment of persistent MRSA lung infection in CF patients in the United States. The Orphan Drug Designation makes AeroVanc eligible for seven years of exclusivity from approval in the United States, and ten years of exclusivity in the European Union and the QIDP designation makes AeroVanc eligible for an additional five years of exclusivity in the United States.
Aironite is an inhaled formulation of sodium nitrite that is developed for the treatment of heart failure patients with preserved ejection fraction (HFpEF). Approximately 50% of patients hospitalized for heart failure have HFpEF and the prevalence of HFpEF is expected to increase as the population ages. Patients with HFpEF have a form of congestive heart failure the prevents a normal amount of blood to be pumped from the heart’s left ventricle.
Patients with HFpEF typically experience general fatigue, and shortness of breath caused by exercise. Evidence points to impaired nitric oxide-cyclic guanosine monophosphate (NO-cGMP) bioavailability as playing a central role in the abnormalities that limit exercise capacity in HFpEF patients. The hope is Aironite will restore NO-cGMP levels thus correcting abnormalities that contribute to the patients’ symptoms.
Aironite has also been selected by the Heart Failure Clinical Research Network</a> (HFN) for evaluation in a 100-patient, multicenter, randomized, double-blind, placebo-controlled, Phase 2 clinical trial. The HFN is made up of premier clinical centers located across North America and was established to study treatments for heart failure. Savara will provide test materials, nebulizers, and regulatory, technical, and additional financial support.
