BRIDGEWATER, N.J., Feb. 23, 2018 (GLOBE NEWSWIRE) -- Insmed Incorporated (Nasdaq:INSM), a global biopharmaceutical company focused on the unmet needs of patients with rare diseases, today reported financial results for the fourth quarter and full year ended December 31, 2017 and provided a business update.

“Last year proved to be pivotal for Insmed in our efforts toward building a company that will transform the lives of patients living with serious rare diseases.  We are preparing for an even greater transformation in 2018 as we anticipate the launch of what would be the first approved inhaled therapy for the treatment of refractory NTM lung disease caused by MAC in the United States,” said Will Lewis, President and Chief Executive Officer of Insmed. “The data reported from our ALIS program, together with our ongoing regulatory and pre-commercial activities, puts us on a trajectory to significantly help patients afflicted by this disease.  We look forward to further expanding our global reach from the U.S. and Europe to include Japan.  Having successfully completed a public offering in January, we are in a solid financial position to fully fund our key strategic activities, and we look forward to sharing our progress throughout the year.”

Corporate Update

INS-212 and INS-312 Interim Results as of December 2017

In January, Insmed announced interim results from its INS-312 study, a 12-month extension study for patients who completed six months of treatment in the INS-212 study, but did not demonstrate culture conversion by Month 6, as well as long-term durability data from its INS-212 study evaluating ALIS + guideline-based therapy (GBT) vs. GBT alone in adult patients with nontuberculous mycobacterial (NTM) lung disease caused by Mycobacterium avium complex (MAC). Patients in either arm of the INS-212 study who did not achieve culture conversion by Month 6 had the option to enroll in INS-312 at Month 8.

• Sputum culture conversion results seen through December 2017 in INS-312 for GBT non-converters who crossed over to treatment with ALIS + GBT (28%) are consistent with sputum culture conversion observed in top-line results from INS-212 (29%).
• INS-312 interim descriptive data demonstrate that continued treatment with ALIS + GBT results in more patients achieving culture conversion, with 12% of prior non-converters from INS-212 ALIS + GBT achieving culture conversion by Month 6 in INS-312.
• INS-212 interim data show that durability of culture conversion three months off of all treatment, which the Company believes will be the endpoint required to support full regulatory approval, is substantially higher in ALIS + GBT (61%) vs. GBT alone (0%).
• Serious treatment emergent adverse events observed in INS-312 are similar to those seen in INS-212 and remain consistent with those seen with the use of inhaled antibiotics. As of December 2017, the dropout rate in INS-312 is 24%.
• The Company plans to continue to monitor and evaluate patients throughout the duration of the INS-212 study and expects to report additional data in late 2018 or early 2019 when the INS-312 study has completed its full 12 months and the data has been analyzed pursuant to its statistical analysis plan as agreed with FDA.

New U.S. Patent Issued Extends ALIS Intellectual Property Protection

Earlier this week, Insmed announced that the United States Patent and Trademark Office issued U.S. Patent Number 9,895,385 concerning methods for treating NTM lung infections, including NTM lung infections caused by MAC, with ALIS. The claims of the patent relate to methods for treating MAC lung infections via administration of ALIS to non-cystic fibrosis patients by nebulization once daily for a defined treatment period.  The patent extends previously existing patent coverage for ALIS by sixteen months, from January 2034 into May 2035.

Litigation Update

Insmed announces that the U.S. District Court for the District of New Jersey granted the Company’s motion to dismiss in the 2016 securities class action lawsuit brought against the Company and certain of its officers and directors. On February 15, 2018, the court dismissed the lawsuit without prejudice, meaning that the plaintiff has 30 days from the date of the order to file a second amended complaint.

Insmed Announces Key Management Promotions

Insmed also announces the promotions of Christine Pellizzari to the position of Chief Legal Officer from General Counsel and Corporate Secretary, and Nicole Schaeffer to Chief People Strategy Officer from Senior Vice President, Human Resources and Corporate Services.

Fourth Quarter Financial Results

For the fourth quarter of 2017, Insmed reported a net loss of $65.4 million, or $0.85 per share, compared with a net loss of $68.4 million, or $1.10 per share, for the fourth quarter of 2016.

Research and development expenses were $33.9 million for the fourth quarter of 2017, compared with $54.9 million for the fourth quarter of 2016. The decrease was primarily due to a one-time $30.0 million upfront payment related to INS1007 in October 2016, partially offset by an increase in expenses associated with the development of INS-1007 and higher compensation and related expenses due to an increase in headcount, as compared to the fourth quarter of 2016.

General and administrative expenses for the fourth quarter of 2017 were $31.4 million, compared with $12.2 million for the fourth quarter of 2016. The increase was primarily due to higher expenses related to our pre-commercial planning activities for ALIS, a one-time payment to reduce the royalty owed to PARI Pharma GmbH and higher compensation and related expenses due to an increase in headcount, as compared to the fourth quarter of 2016.

Balance Sheet and Cash Guidance 

As of December 31, 2017, Insmed had cash and cash equivalents of approximately $381.2 million and debt of $55.0 million.  These figures do not reflect the net proceeds of $435.8 million received in January 2018 from the public offering of $450 million of 1.75% senior convertible notes due in 2025. The Company's operating expenses for the fourth quarter of 2017 were $65.4 million and $188.9 million for the full year of 2017.  The cash-based operating expenses for the fourth quarter of 2017 were approximately $59.9 million and $167.9 million for the full year of 2017.  The Company intends to repay the existing debt from Hercules Capital on February 28, 2018.  The total payment including the backend fee and early prepayment penalty will be approximately $58 million.

The Company is investing in the following key activities in 2018: (i) the build-out of the commercial organization to support global expansion activities for ALIS, (ii) manufacturing of commercial inventory and build out of an additional third-party manufacturing facility and (iii) clinical activities for ALIS and the phase 2 development program for INS-1007, along with advancement of other pipeline programs.  As a result of these activities, Insmed expects cash based operating expenses and capital and other cash investments to be in the range of $145 million to $165 million for the first half of 2018.

Non-GAAP Financial Measures

In addition to the United States generally accepted accounting principles (GAAP) results, this earnings release includes cash-based operating expenses, a non-GAAP financial measure, which Insmed defines as total operating expenses excluding stock-based compensation expense and depreciation expense. A reconciliation of this non-GAAP financial measure to its most directly comparable GAAP financial measure is presented in the table attached to this press release.

Management believes that this non-GAAP financial measure is useful to both management and investors in analyzing our ongoing business and operating performance. Management believes that providing non-GAAP information to investors, in addition to the GAAP presentation, allows investors to view our financial results in the way that management views financial results.  Management does not intend the presentation of this non-GAAP financial measure to be considered in isolation or as a substitute for results prepared in accordance with GAAP. In addition, this non-GAAP financial measure may differ from similarly named measures used by other companies.

About NTM Lung Disease

NTM lung disease is a rare and serious disorder associated with increased rates of morbidity and mortality. There is an increasing prevalence of lung disease caused by NTM, and we believe it is an emerging public health concern worldwide. Patients with NTM lung disease may experience a multitude of symptoms such as fever, weight loss, cough, lack of appetite, night sweats, blood in the sputum, and fatigue. Patients with NTM lung disease frequently require lengthy hospital stays to manage their condition.  We are not aware of any approved inhaled therapies specifically indicated for refractory NTM lung disease caused by MAC in North America, Japan or Europe.  Current guideline-based approaches involve use of multi-drug regimens not approved for the treatment of NTM lung disease, and treatment can be as long as two years or more.

The prevalence of human disease attributable to NTM has increased over the past two decades. In a decade long study (1997 to 2007), researchers found that the prevalence of NTM lung disease in the U.S. was increasing at approximately 8% per year and that NTM patients on Medicare over the age of 65 were 40% more likely to die over the period of the study than those who did not have the disease. In the U.S., we estimate there will be between 75,000 and 105,000 patients with diagnosed NTM lung disease in 2018, of which we expect 40,000 to 50,000 will be treated for NTM lung disease caused by MAC.  We expect that between 10,000 and 15,000 of these patients will be refractory to treatment.  In Japan, we estimate there will be between 125,000 and 145,000 patients with diagnosed NTM lung disease in 2018, with approximately 60,000 to 70,000 of those patients being treated for NTM lung disease caused by MAC and 15,000 to 18,000 of these treated patients being refractory to treatment. We also estimate there will be approximately 14,000 patients with diagnosed NTM lung disease in the EU5 (comprised of France, Germany, Italy, Spain and the United Kingdom) in 2018, of which we estimate approximately 4,400 will be treated for NTM lung disease caused by MAC and approximately 1,400 of these treated patients will be refractory to treatment.  

About ALIS

ALIS is a novel, inhaled, once-daily formulation of amikacin that is in late-stage clinical development for adult patients with treatment-refractory NTM lung disease caused by MAC. Amikacin solution for parenteral administration is an established drug that has activity against a variety of NTM; however, its use is limited by the need to administer it intravenously and by toxicity to hearing, balance, and kidney function. Insmed's advanced pulmonary liposome technology uses charge neutral liposomes to deliver amikacin directly to the lung where it is taken up by the lung macrophages where the NTM infection resides. This prolongs the release of amikacin in the lungs while minimizing systemic exposure thereby offering the potential for decreased systemic toxicities. ALIS’s ability to deliver high levels of amikacin directly to the lung distinguishes it from intravenous amikacin. ALIS is administered once daily using an optimized, investigational eFlow® Nebulizer System manufactured by PARI Pharma GmbH (PARI), a portable aerosol delivery system.

About CONVERT (INS-212) and INS-312

CONVERT is a randomized, open-label, global Phase 3 trial designed to confirm the culture conversion results seen in Insmed’s Phase 2 clinical trial of ALIS in patients with refractory NTM lung disease caused by MAC. CONVERT is being conducted in 18 countries at more than 125 sites. The primary efficacy endpoint is the proportion of patients who achieve culture conversion at Month 6 in the ALIS plus GBT arm compared to the GBT-only arm. Patients who achieve culture conversion by Month 6 will continue in the CONVERT study for an additional 12 months of treatment following the first monthly negative sputum culture. Patients who do not culture convert have the option of enrolling in our INS-312 study. INS-312 is a single-arm open-label extension study for patients who completed six months of treatment in the INS-212 study, but did not demonstrate culture conversion by Month 6. Under the study protocol, patients in the ALIS plus GBT arm of the INS-212 study will receive an additional 12 months of ALIS plus GBT. Patients who crossed over from the GBT-only arm of the INS-212 study will receive 12 months of treatment of ALIS + GBT.

About Insmed
