Savara Provides Update on Case Reports of Inhaled Granulocyte-Macrophage Colony Stimulating Factor for the Treatment of Nontuberculous Mycobacteria Infection
AUSTIN, Texas, May 29, 2018 (GLOBE NEWSWIRE) -- Savara, Inc. (NASDAQ:SVRA), an orphan lung disease company, today provided an update on two case reports exploring the use of aerosolized granulocyte-macrophage colony stimulating factor (GM-CSF) for the treatment of Mycobacterium abscessus (M. abscessus), a species of multidrug-resistant nontuberculous mycobacteria (NTM), in individuals living with cystic fibrosis (CF). Notably, culture conversion has now been achieved in both patients, along with meaningful clinical improvement.
The two case reports were initially published in the European Respiratory Journal (ERJ) by Mark E. Wylam, M.D., pulmonologist and critical-care specialist at the Mayo Clinic College of Medicine, and his coworkers. In the published case reports, inhaled GM-CSF eradicated M. abscessus infection in the first subject and precipitated a strong microbiological response in the second subject. Subsequent to the publication, the second subject has now achieved culture conversion without NTM antibiotic treatment.
“This is a remarkable result given that this second subject, unlike the first one, was not treated with NTM antibiotics,” stated Mark E. Wylam, M.D., the senior author of the ERJ publication. “Both subjects remain on aerosolized GM-CSF and have experienced clinically meaningful improvements in weight gain and lung function. I believe these case studies strongly reinforce the scientific rationale for the treatment of NTM lung infection using inhaled GM-CSF, and I look forward to the results of Savara’s ongoing OPTIMA study.”
In Q1 2018 Savara initiated the OPTIMA study, a 30-patient, multi-center, open-label Phase 2a clinical trial to investigate the efficacy and safety of Molgradex for the treatment of chronic NTM lung infection. Subjects with either M. abscessus or Mycobacterium avium complex (MAC) infection are being enrolled, with all subjects having either antibiotic refractory infection or intolerance to standard NTM antibiotics. The trial consists of 24 weeks of Molgradex treatment, followed by a 12-week observational period. The primary endpoint is sputum culture conversion defined as at least three consecutive negative sputum cultures. Secondary endpoints include other microbiological indicators, exercise capacity and patient-reported outcomes.
Patient enrollment in the OPTIMA study is on track to complete in Q3 2018 and topline results are expected in H1 2019. However, as OPTIMA is an open-label study, depending on enrollment and other factors, interim results from the study may be provided in 2018.
About NTM Lung Infection
NTM lung infection is a rare and serious lung disorder associated with increased rates of morbidity and mortality. NTM are naturally-occurring organisms and NTM lung infection can occur when an individual inhales the organism from their environment and develops a slowly progressive and destructive lung disease. NTM lung infection is typically characterized by cough, fatigue and weight loss. NTM infection often becomes chronic and requires long courses of multiple antibiotics, and despite aggressive treatment regimens, treatment failure rates are high, and recurrence of infection common. Chronic NTM lung infection can have a significant impact on quality of life. There are approximately 50,000 to 80,000 individuals affected by NTM lung infection in the U.S., the most common types involving MAC and M. abscessus. There have been few advancements in new systemic treatments for NTM lung infection. However, in a recent Phase 3 clinical trial by Insmed, local delivery of an inhaled form of amikacin directly to the lung was shown to be effective in approximately one third of treatment refractory patients with pulmonary MAC infection, suggesting administration of high local concentrations of drug directly at the site of infection provides an attractive new avenue to improve clinical outcomes in this and other difficult-to-treat chronic lung infections.
Molgradex is an inhaled formulation of recombinant human GM-CSF, in Phase 3 development for autoimmune pulmonary alveolar proteinosis and in Phase 2a development for NTM lung infection. Molgradex is delivered via an investigational eFlow® Nebulizer System (PARI Pharma GmbH). Molgradex has been granted Orphan Drug Designation for the treatment of PAP in the United States and the European Union.
Savara is an orphan lung disease company. Savara's pipeline comprises: Molgradex, an inhaled granulocyte-macrophage colony-stimulating factor, or GM-CSF, in Phase 3 development for autoimmune pulmonary alveolar proteinosis and in Phase 2a development for NTM lung infection; and AeroVanc, a Phase 3 stage inhaled vancomycin for treatment of MRSA lung infection in CF. Savara's strategy involves expanding its pipeline of potentially best-in-class products through indication expansion, strategic development partnerships and product acquisitions, with the goal of becoming a leading company in its field. Savara's management team has significant experience in orphan drug development and pulmonary medicine, identifying unmet needs, developing and acquiring new product candidates, and effectively advancing them to approvals and commercialization.
