SEATTLE--(BUSINESS WIRE)--Aug. 11, 2020-- Alpine Immune Sciences, Inc. (NASDAQ:ALPN), a leading clinical-stage immunotherapy company focused on developing innovative treatments for cancer and autoimmune/inflammatory diseases, today provided a corporate update and reported financial results for the second quarter ended June 30, 2020.

Key Second Quarter 2020 and Subsequent Highlights

• Announced ALPN-101 Option and License Agreement with AbbVie for up to $865 million plus royalties on future sales. In June, Alpine and AbbVie announced an exclusive worldwide option and license agreement for ALPN-101, a first-in-class dual CD28/ICOS costimulation antagonist. Under the terms of the agreement, Alpine received an upfront payment of $60 million and is eligible to receive up to an aggregate of $805 million for exercise of the option and success-based development, regulatory, and commercial milestones. In addition, Alpine is eligible to receive tiered royalties on net sales of ALPN-101. In exchange, AbbVie received an exclusive option to an exclusive license for ALPN-101.
• Initiated the first-in-human, Phase 1 Trial of ALPN-202. In June, Alpine announced the first patient had been successfully dosed in its NEON-1 Phase 1 study of ALPN-202, a first-in-class conditional CD28 costimulator and dual checkpoint inhibitor, in advanced malignancies.
• Raised $60 Million in a Private Placement. In July, Alpine raised $60 million in gross proceeds through a private placement led by Omega Funds with participation from Avidity Partners, EcoR1 Capital, LLC, Invus Public Equities, L.P., and Samsara BioCapital, among others. Alpine intends to use the net proceeds to fund the development of its clinical and preclinical pipeline as well as for general corporate purposes.
• Presented at Multiple Scientific Meetings. From April to June, Alpine made a number of presentations at important scientific conferences including:
  • ALPN-202 Study Design Presented at AACR I - “NEON-1: A first-in-human phase I open-label study of ALPN-202, a conditional CD28 costimulator and dual checkpoint inhibitor, in advanced malignancies.”
  • ALPN-202 Additional Preclinical Data at AACR II - “ALPN-202 combines checkpoint inhibition with conditional T cell costimulation to overcome T cell suppression by M2c macrophages and improve the durability of engineered T cell anti-tumor responses.”
  • Novel Dual BAFF/APRIL Inhibitory Domains (ALPN-303) for B cell Mediated Autoimmune Diseases at EULAR 2020 - “B Cell Modulatory Variant TNF Receptor Domains (vTDs) Identified by Directed Evolution to Inhibit BAFF and APRIL, Alone or Combined with Variant Ig Domains (vIgD™) that Inhibit T Cell Costimulation, for the Treatment of Severe Autoimmune and/or Inflammatory Disease.”
  • ALPN-101 Phase 1 Trial Data at EULAR 2020 - “A Double Blind, Placebo Controlled, Single Ascending Dose (SAD) and Multiple Ascending Dose (MAD) Study of ALPN-101, a First-in-Class Dual ICOS/CD28 Antagonist, in Healthy Volunteers (HV).”

“The highlight of Alpine’s second quarter was the signing of a transformative option and license agreement for ALPN-101 with AbbVie. This highly competitive deal provides validation of our scientific approach and our unique Directed Evolution platform,” said Mitchell H. Gold, M.D., Executive Chairman and Chief Executive Officer of Alpine. “Importantly, the progression of ALPN-101 is now supported by our AbbVie partnership. Our platform has yielded multiple product candidates in addition to ALPN-101. First among these is ALPN-202, for which we dosed the first patient in our NEON-1 Phase 1 study during the quarter. In addition, we were able to further strengthen our balance sheet via a $60 million private financing, adding a number of high-quality institutions to our shareholder roster. I am very proud of all we have achieved of late and I look forward to further updating you on our progress.”

Financial Highlights

• As of June 30, 2020, Alpine had cash, cash equivalents, restricted cash, and short-term investments totaling $90.5 million. This balance includes the $60 million upfront cash payment from AbbVie for the option to license ALPN-101, but does not include the $60 million of gross proceeds from our July private placement. Taking the recent private placement into account, we ended July 31, 2020 with $147.5 million in cash, cash equivalents, restricted cash, and short-term investments. This compares to $36.1 million as of March 31, 2020.
• Net cash provided by operating activities for the six months ended June 30, 2020 was $44.8 million compared to $19.1 million in net cash used for the same period in 2019.
• Alpine recorded a net loss of $9.9 million and $11.9 million for the second quarters ended June 30, 2020 and 2019, respectively, and $15.5 million and $24.2 million for the six months ended June 30, 2020 and 2019, respectively.
• Research and development expenses for the second quarter ended June 30, 2020 were $7.1 million compared to $10.2 million for the second quarter ended June 30, 2019. For the first six months of 2020 they were $12.0 million compared to $20.5 million for the same period in 2019.
• General and administrative expenses for the second quarter ended June 30, 2020 were $3.3 million compared to $2.6 million for the second quarter ended June 30, 2019, and $5.1 million and $4.9 million for the six months ended June 30, 2020 and 2019, respectively.

Cash Guidance

Taking the recent private placement into account, Alpine ended July 31, 2020 with $147.5 million in cash, cash equivalents, restricted cash, and short-term investments. Alpine expects that its current cash resources, combined with the potential $75 million in pre-option exercise milestones payable under its option and license agreement with AbbVie, for the development and commercialization of ALPN-101, are sufficient to fund Alpine's planned operations through 2024, including a planned Phase 2 study of ALPN-101 in systemic lupus erythematosus and the further development of ALPN-202 and ALPN-303.

Management’s Discussion and Analysis of Financial Condition and Results of Operation - Liquidity and Capital Resources” in Alpine’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2020, which Alpine anticipates filing with the Securities and Exchange Commission on or about August 11, 2020.

About ALPN-101

ALPN-101 is a novel Fc fusion protein of a human inducible T cell costimulatory ligand (ICOSL) variant immunoglobulin domain (vIgD™), a first-in-class therapeutic designed to inhibit simultaneously the CD28 and ICOS inflammation pathways. CD28 and ICOS are closely related costimulatory molecules with partially overlapping roles in T cell activation likely playing a role in multiple autoimmune and inflammatory diseases. In June 2020, Alpine and AbbVie signed an option and license agreement for the development and commercialization of ALPN-101. During the option period, Alpine will conduct a phase 2 study in systemic lupus erythematosus. Upon exercise of the option, AbbVie will conduct all future clinical development, manufacturing, and commercialization activities for ALPN-101.

About ALPN-202

ALPN-202 is a first-in-class, conditional CD28 costimulator and dual checkpoint inhibitor with the potential to improve upon the efficacy of combined checkpoint inhibition while limiting significant toxicities. Preclinical studies of ALPN-202 have successfully demonstrated superior efficacy in tumor models compared to checkpoint inhibition alone. A phase 1 trial of ALPN-202 in advanced malignancies (NEON-1, NCT04186637) is currently enrolling.

About ALPN-303

ALPN-303 is a dual BAFF/APRIL B cell cytokine antagonist under development for the treatment of B cell-mediated inflammatory diseases. BAFF and APRIL are clinically validated targets, and in preclinical studies, ALPN-303 appears to have superior activity compared to other available inhibitors of these pathways, suggesting the potential to be best-in-class. Development activities to enable clinical trials have been initiated.
