“Results from the open-label period of IMPALA reaffirm our strong belief that Molgradex could improve outcomes for patients with aPAP, a rare and debilitating lung disease,” said Rob Neville, Chief Executive Officer, Savara. “We continue our conversations with the FDA, as our highest priority is to get clarity from the agency regarding the design and endpoints of a second Phase 3 study in aPAP.”

PROGRAM UPDATES

Molgradex for aPAP

• Announced the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation for Molgradex, an inhaled formulation of recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF), for the treatment of aPAP.
• Working in consultation with the FDA to plan a second Phase 3 study.
• Completed enrollment in IMPALA-X, an open-label multicenter extension study to determine the long-term safety and use of Molgradex in patients with aPAP. Sixty out of 64 eligible patients enrolled in the study.

The Company today announced results from the open-label follow-up period of IMPALA, a Phase 3 study that evaluated Molgradex for the treatment of aPAP. The results, found below, will be discussed on today’s conference call/webcast. Data from the double-blind period of IMPALA were presented at the 2019 European Respiratory Society (ERS) International Congress and can be found on the Articles and Publications page of Savara’s website.

IMPALA Study Design

IMPALA was a randomized, double-blind, placebo-controlled clinical study designed to compare the efficacy and safety of Molgradex with placebo in patients with aPAP. Patients were randomized to receive treatment for 24 weeks in one of three arms: 1) Molgradex 300 µg administered once daily continuously over 24 weeks, 2) Molgradex 300 µg, and matching placebo, each administered once daily every other week, or 3) inhaled placebo administered once daily continuously over 24 weeks. At the end of the 24-week double-blind period, all treatment arms rolled into a 24-week open-label follow-up period and received Molgradex 300 µg administered once daily every other week.

The primary endpoint was change from baseline in alveolar-arterial oxygen gradient, or (A-a)DO₂, to week 24. In addition, three key secondary endpoints―St. George’s Respiratory Questionnaire (SGRQ), six-minute walk distance (6MWD), and time to requirement for whole lung lavage (WLL)―along with multiple other secondary and exploratory endpoints were assessed.

IMPALA Open-Label Period

A total of 128 patients completed the open-label period of IMPALA. Sixty-eight patients enrolled in the open-label period through week 48. The other 60 patients were enrolled under an early protocol version of the study through week 72.

During the double-blind period, a dose frequency dependency was observed in most endpoints with continuous administration of Molgradex showing higher efficacy than placebo and continuous administration appearing to result in higher efficacy than once daily dosing every other week. Open-label results presented below focus on the group that had received a once daily continuous dose (OD) of Molgradex during the double-blind period versus those that had received once daily placebo (PBO) during the double-blind period―both of which received once daily dosing every other week during the open-label period.

Improvements in Two Independent Measures of Gas Exchange

In addition to (A-a)DO₂, diffusing capacity of the lungs for carbon monoxide (DLCO) is another way to assess gas exchange. As with (A-a)DO₂, DLCO is impaired in patients with aPAP and was assessed as an additional secondary endpoint in the study.

Patients who had been in the OD treatment group during the double-blind period:

Improvement from baseline was maintained or progressively increased in these patients during the open-label period of the study. The average (A-a)DO₂ improvement in the double-blind period was -12.1 mmHg at week 24, compared to an average improvement from baseline in the open-label period of -12.2 mmHg and -18.8 mmHg at weeks 48 and 72, respectively. (See Figure 1.) The mean absolute improvement in DLCO during the double-blind period was 11.6% predicted at week 24, compared to a mean absolute improvement from baseline in the open-label period of 13.7% and 19.8% predicted at weeks 48 and 72, respectively.

Patients who had been in the PBO group during the double-blind period:

PBO patients that transitioned to active drug in the open-label period showed similar average improvements to those who had been in the double-blind OD group. The average (A-a)DO₂ improvement in the double-blind period was -8.8 mmHg at week 24, compared to an average improvement from baseline in the open-label period of -14.6 mmHg and -17.0 mmHg at weeks 48 and 72, respectively. (See Figure 1.) The mean absolute improvement in DLCO during the double-blind period was 3.9% predicted at week 24, compared to a mean absolute improvement from baseline in the open-label period of 14.2% and 18.0% predicted at weeks 48 and 72, respectively.

Improvements in SGRQ

Patients who had been in the OD treatment group during the double-blind period:

Changes from baseline in the SGRQ were maintained and further increased with longer exposure to Molgradex. The average improvement during the double-blind period was -12.3 points at week 24, compared to an average improvement from baseline in the open-label period of -13.1 and -17.4 points at weeks 48 and 72, respectively. (See Figure 2.)

Patients who had been in the PBO group during the double-blind period:

At the end of the open-label period, PBO patients that transitioned to active drug showed similar average improvements in the SGRQ to those who received OD in the double-blind period. The average improvement during the double-blind period was -4.7 points at week 24, compared to an average improvement from baseline in the open-label period of -14.7 and -14.9 points at weeks 48 and 72, respectively. (See Figure 2.)

Improvements in 6MWD

Patients who had been in the OD treatment group during the double-blind period:

The average improvement during the double-blind period was 39.6 meters at week 24, compared to an average improvement from baseline in the open-label period of 48.9 meters and 71.7 meters at weeks 48 and 72, respectively.

Patients who had been in the PBO group during the double-blind period:

The average improvement during the double-blind period was 6.0 meters at week 24, compared to an average improvement from baseline in the open-label period of 40.4 meters and 29.9 meters at weeks 48 and 72, respectively.

Improvements in WLL

During the double-blind period of the study, 33 whole lung lavage procedures were required, including 9 in the continuous group compared to 17 in the placebo group. During the open-label period of the study only 5 whole lung lavage procedures were conducted. The pre-study rate of WLL was 0.8 procedures per patient year, compared to 0.055 procedures per patient year during the open-label period of the study. (See Figure 3.)

The Company intends to present more comprehensive data from the IMPALA study at an upcoming scientific conference and/or submit it for consideration in a peer-reviewed journal.

Molgradex for NTM Lung Infection

The Company today announced top line microbiology results from OPTIMA, a Phase 2a, exploratory, open-label, non-controlled clinical study evaluating Molgradex for the treatment of NTM lung infection in patients not affected by cystic fibrosis (CF). The results, found below, will be discussed on today’s conference call/webcast.

OPTIMA Study Design

The OPTIMA study, comprised of a 48-week treatment period and a 12-week follow-up period, enrolled patients with either Mycobacterium avium complex (MAC) infection, or the more difficult-to-treat Mycobacterium abscessus (MABSC) infection. Prior to enrolling, all patients were diagnosed with bronchiectasis, with all except one having radiological evidence of nodular multifocal and/or cavitary bronchiectasis. Two treatment groups of patients were recruited into the study, both of which received Molgradex 300 µg administered once daily. Treatment group one consisted of patients who remained sputum culture positive while currently on a multidrug NTM guideline-based anti-mycobacterial regimen, which had been ongoing for at least six-months prior to the baseline visit. Treatment group two consisted of patients who remained sputum culture positive, but either stopped a multidrug NTM guideline-based anti-mycobacterial regimen at least 28 days prior to screening due to lack of response or intolerance, or never started such treatment.

Summary of Efficacy and Safety Results

Thirty-two patients were treated in the study, of which 24 had MAC infection and 8 had MABSC infection. Of the patients with MAC infection, 11 were in treatment group one and 13 were in treatment group two. Of the patients with MABSC infection, 3 were in treatment group one and 5 were in treatment group two.

Results from the Intention-to-Treat (ITT) population showed that 5 out of 24 patients (21%) with MAC infection achieved a sputum culture conversion, defined as at least three consecutive sputum samples without growth of nontuberculous mycobacteria during the treatment period. Two of these patients, one from each treatment group, remained culture negative through the 12-week follow-up period. Sputum culture conversions were not observed in patients with MABSC infection.

Among the 32 treated patients in the safety population, 14 experienced serious adverse events (SAEs), one of which was considered potentially treatment related. The most common SAE was infective exacerbation of bronchiectasis. Three patients died during the study, with all deaths unlikely related to the study treatment.

The Company will continue to assess data from the OPTIMA study to better understand the clinical outcomes seen in some patients. Next steps for the NTM program will be determined once results from ENCORE, an ongoing Phase 2a, open-label, non-controlled study evaluating Molgradex for the treatment of NTM in patients living with CF, are available.

The Company intends to submit the full data set from OPTIMA for consideration at an upcoming scientific conference.

AeroVanc

Enrollment continues in AVAIL, a pivotal Phase 3 clinical study of AeroVanc for the treatment of persistent methicillin-resistant Staphylococcus aureus (MRSA) lung infection in CF. Total target enrollment is 200 patients. The adult population is fully enrolled, and the Company has enrolled 133 patients out of a target of 150 in the primary analysis population (younger patients between 6-21 years of age). The Company will continue enrollment until Q2 2020 and anticipates enrolling a total of ~140 younger patients. Top line results are expected in early 2021.

Fourth Quarter Financial Results (Unaudited)

Savara's net loss for the fourth quarter of 2019 was $31.7 million, or $(0.72) per share, compared with a net loss of $10.5 million, or $(0.29) per share, for the fourth quarter of 2018. Research and development expenses were $8.7 million for the fourth quarter of 2019, compared with $9.9 million for the fourth quarter of 2018.

General and administrative expenses for the fourth quarter of 2019 and 2018 were $3.3 million.

As of December 31, 2019, the Company had cash of $49.8 million and short-term investments of $72.0 million. Operating expenses for the fourth quarter of 2019 were approximately $31.5 million which included $19.4 million in noncash goodwill impairment charges. The Company ended the fourth quarter of 2019 with approximately $25.1 million outstanding in short- and long-term debt on its balance sheet, which was used and will continue to be used to bolster operations and advance the development of drug candidates.

Fiscal Year 2019 Financial Results

The Company’s net loss for the year ended December 31, 2019 was $78.2 million, or $(1.95) per share, compared with a net loss of $61.5 million, or $(1.85) per share for the year ended December 31, 2018.

Research and development expenses increased by $1.6 million, or 4.3%, to $38.8 million for the year ended December 31, 2019 from $37.2 million for the year ended December 31, 2018. The increase was primarily due to increased development and regulatory costs associated with the development of Molgradex for the treatment of aPAP, NTM, and NTM in patients with CF as well as development costs associated with the enrollment and other Phase 3 study activities of the AeroVanc program.

General and administrative expenses increased by $2.4 million, or 22.8%, to $13.1 million for the year ended December 31, 2019 from $10.7 million for the year ended December 31, 2018. The increase was primarily due to increased commercial costs related to market research and similar activities for Molgradex, increases in personnel costs, legal, accounting, insurance, business development, and other operating activities.

During the year ended December 31, 2019, the Company recognized $26.9 million in noncash impairment charges to the carrying value of the Company’s goodwill following the results of the IMPALA Phase 3 study of Molgradex for the treatment of aPAP. During the year ended December 31, 2018, the Company recognized a $21.7 million noncash impairment charge against the carrying value of acquired IPR&D related to an ancillary drug candidate, previously assumed by Savara in the 2017 merger, due to unfavorable results from the Phase 2 study. The Company is no longer supporting or pursuing this ancillary drug candidate.

About IMPALA

The IMPALA clinical study was a randomized, double-blind, placebo-controlled, Phase 3 clinical study of Molgradex in 138 patients with aPAP. Patients were randomized to receive treatment for 24 weeks in one of three arms: 1) Molgradex 300 µg administered once daily continuously over 24 weeks, 2) Molgradex 300 µg, and matching placebo, each administered once daily every other week, or 3) inhaled placebo administered once daily continuously over 24 weeks. At the end of the 24-week double-blind period, all treatment arms rolled into a 24-week open-label follow-up period and received Molgradex 300 µg administered once daily every other week. The primary endpoint of the study was change from baseline in alveolar-arterial oxygen gradient, or (A-a)DO₂, a commonly used measure of oxygenation impairment, to week 24. In addition, three key secondary endpoints―St. George’s Respiratory Questionnaire (SGRQ), six-minute walk distance (6MWD), and time to requirement for whole lung lavage (WLL)―along with multiple other secondary and exploratory endpoints were assessed to determine improvement in the disease pathology and pathophysiology, clinical symptoms, and function.

About OPTIMA

The OPTIMA clinical study was an exploratory, open-label, non-controlled, multi-center, Phase 2a clinical study of Molgradex in 32 patients with persistent pulmonary NTM lung infection. OPTIMA enrolled patients with chronic Mycobacterium avium complex (MAC) infection or Mycobacterium abscessus (MABSC) infection, with all patients having either antibiotic refractory infection or intolerance to standard NTM antibiotics. Patients with cystic fibrosis were not enrolled. The study comprised a 48-week treatment period and a 12-week follow-up period. Two groups of patients were recruited into the OPTIMA study. Treatment group one consisted of patients who remained sputum culture positive while currently on a multidrug NTM guideline-based anti-mycobacterial regimen, which had been ongoing for at least six months prior to the baseline visit. Treatment group two consisted of patients who remained sputum culture positive, but either stopped a multidrug NTM guideline-based anti-mycobacterial regimen at least 28 days prior to screening due to lack of response or intolerance, or never started such treatment.

The primary endpoint in the study was sputum culture conversion, defined as at least three consecutive sputum samples without growth of nontuberculous mycobacteria. Secondary endpoints included: (i) the number of patients with sputum smear conversion to negative, defined as at least three consecutive negative acid-fast bacilli (AFB) stained sputum smears on microscopy among patients who were smear positive at baseline, (ii) the number of patients with durable sputum culture conversion, defined as sputum culture conversion at or before week 48 and culture still negative for growth of nontuberculous mycobacteria at 12-week follow-up, (iii) the number of patients with durable sputum smear conversion, defined as sputum smear conversion at or before week 48 and AFB stained smear still negative for nontuberculous mycobacteria at 12-week follow-up among patients who were smear positive at baseline, and (iv) other microbiological indicators, exercise capacities, and patient reported outcomes.

About AVAIL

AVAIL is a randomized, double-blind, placebo-controlled, Phase 3 study of vancomycin hydrochloride inhalation powder (AeroVanc) in people living with cystic fibrosis who have methicillin-resistant Staphylococcus aureus (MRSA) lung infection. Target enrollment is 200 patients. During Period 1 of the study, patients are randomly assigned in a blinded 1:1 fashion to receive either AeroVanc (30 mg) twice daily, or placebo, by inhalation for 24 weeks or 3 dosing cycles. A dosing cycle is defined as 28 days of treatment followed by 28 days of observation. During Period 2 of the study, patients receive open-label AeroVanc (30 mg) twice daily for an additional 24 weeks or 3 dosing cycles, to evaluate the long-term safety of AeroVanc.

The primary endpoint is the mean absolute change in FEV1 percent predicted from baseline, which will be analyzed sequentially at week 4 (the end of cycle 1), at week 12 (the end of cycle 2) and at week 20 (the end of cycle 3). Analysis of the primary endpoint will be based on patients between 6-21 years of age. Secondary efficacy endpoints include: (i) time-to-use of another antibiotic medication for pulmonary infection, (ii) the number of successful FEV1-response cycles a patient achieves over Period 1 (weeks 4, 12, and 20), (iii) relative change from baseline in FEV1 percent predicted at weeks 4 and 20, (iv) change from baseline CF Questionnaire-Revised scores at weeks 4 and 20 and (v) change from Baseline in CF Respiratory Symptom Diary-Chronic Respiratory Symptom scores at weeks 4 and 20.
