Alpine Immune Sciences Provides Corporate Update and Reports Third Quarter 2018 Financial Results

SEATTLE--(BUSINESS WIRE)--Alpine Immune Sciences, Inc. (NASDAQ:ALPN), a leading immunotherapy company focused on developing innovative treatments for autoimmune/inflammatory diseases and cancer, today provided a corporate update and reported financial results for the third quarter ended September 30, 2018.

“We have had a highly productive quarter as we continue to rapidly advance our two lead programs, ALPN-101 for the treatment of autoimmune/inflammatory disease and ALPN-202 for oncology, toward our first human clinical trials,” said Mitchell H. Gold, M.D., Executive Chairman and Chief Executive Officer of Alpine. “We are excited by the strong cadence of preclinical data to be presented at upcoming scientific meetings in the fourth quarter, highlighting the potential of our molecules as novel, next generation immunotherapies.”

Corporate Development Highlights

• ALPN-101 preclinical data presented at ACR/ARHP and ANA annual meetings: In October, we presented positive results from our lead autoimmune/inflammatory program, ALPN-101, a dual ICOS/CD28 antagonist, in experimental models of inflammatory arthritis and multiple sclerosis. The data were presented in poster sessions at the American College of Rheumatology (ACR)/Association of Rheumatology Health Professionals (ARHP) Annual Meeting in Chicago as well as the 143rd Annual Meeting of the American Neurological Association (ANA) in Atlanta.
• Advancing both lead programs towards the clinic: ALPN-101 remains on track to advance to clinical trials and we anticipate completing all tasks necessary to commence clinical trials in the first quarter of 2019. ALPN-202 pre-clinical development activities continue as planned with the goal of human clinical trials starting in 2019.
• Two upcoming poster presentations at the Society for Immunotherapy of Cancer (SITC) 33rd Annual Meeting: We will have two poster presentations at the upcoming SITC annual meeting on Friday, November 9, 2018 and Saturday, November 10, 2018 in Washington, D.C.

Third Quarter 2018 Financial Results

• We ended the third quarter of 2018 with $62.0 million in cash, cash equivalents and short-term investments, compared to $81.2 million as of December 31, 2017.
• Net loss for the third quarter of 2018 was $12.1 million, compared to a net income of $2.1 million for the same period in 2017. The increase in net loss is primarily attributable to our preparations to initiate human clinical trials for ALPN-101 and ALPN-202 in 2019.
• Research and development expenses for the third quarter of 2018 were $10.5 million, compared to $2.8 million for the same period in 2017. The increase was primarily attributable to increases in contract manufacturing and process development for ALPN-101 and ALPN-202 and direct research activities, in addition to personnel-related expenses, overhead and facilities.
• General and administrative expenses for the third quarter of 2018 were $1.9 million, relatively flat, compared to $1.9 million for the same period of 2017. There was an insignificant net decrease, primarily attributable to a decrease in professional and legal service fees related to merger costs incurred during the 2017 period, partially offset by increases in personnel-related expenses and costs incurred to support the growth and expansion of the business, overhead and facilities.

Cash Guidance

We expect to have sufficient cash to fund operations into 2020, including the clinical advancement of ALPN-101 for the treatment of autoimmune/inflammatory diseases and ALPN-202 for the treatment of cancer.

About Alpine Immune Sciences, Inc.

Alpine Immune Sciences, Inc. is committed to developing new modalities of functional immune therapeutics. Alpine is employing directed evolution to create potentially powerful multifunctional immunotherapies to improve patients’ lives. Supported by promising preclinical data, we aim to have two programs in the clinic in 2019. The first, ALPN-101 for autoimmune/inflammatory diseases, is a dual ICOS/CD28 antagonist, engineered to reverse pathogenic immune responses. The second, ALPN-202 for cancer, is a dual PD-L1/CTLA-4 antagonist and PD-L1-dependent CD28 T cell costimulator intended to combine checkpoint inhibition with a necessary costimulation signal - an approach currently absent from approved checkpoint therapies. Alpine is backed by world-class research capabilities, a highly-productive scientific platform, and a proven management team. For more information, visit www.alpineimmunesciences.com.
