Alpine Immune Sciences Reports First Quarter 2024 Financial Results

Alpine Immune Sciences, Inc. (NASDAQ:ALPN), a leading clinical-stage immunotherapy company focused on developing innovative treatments for autoimmune and inflammatory diseases, today reported financial results for the first quarter ended March 31, 2024.

On April 10, 2024, Vertex Pharmaceuticals Incorporated (NASDAQ:VRTX) and Alpine announced that the companies had entered into a definitive agreement under which Vertex will acquire Alpine for $65 per share in cash. The transaction was unanimously approved by both the Vertex and Alpine Boards of Directors and is anticipated to close in the second quarter of 2024.

First Quarter 2024 Financial Results

Cash Position and Runway: As of March 31, 2024, Alpine's cash and investments totaled $362.4 million compared to $368.2 million as of December 31, 2023. The Company anticipates its current cash and investments are sufficient to fund planned operations into 2026.

Collaboration Revenue: For the three months ended March 31, 2024, collaboration revenue was $7.0 million compared to $9.4 million for the same period in 2023. The decrease in collaboration revenue relates primarily to a $1.8 million decrease in Amgen revenue, due to work progressing simultaneously during the 2023 period on our second Research Program, which was completed in 2023, as well as on our first Research Program, which as of March 31, 2024, was also nearing completion. AbbVie revenue decreased by $0.2 million primarily due to lower contributed employee hours. All services related to our Adaptimmune collaboration were completed by June 2023.

Research and Development Expense: For the three months ended March 31, 2024, research and development expense, inclusive of non-cash expenses, was $22.5 million compared to $19.6 million for the same period in 2023. The increase of $2.9 million was driven by an $4.8 million increase in povetacicept costs, primarily related to higher clinical trial, process development and manufacturing costs as we continue our RUBY studies, and a $1.6 million increase in personnel costs. This increase was partially offset by a $2.7 million decrease in acazicolcept costs, which was primarily due to decreased manufacturing costs during the 2024 period, and a $1.4 million decrease in davoceticept costs, which was due to study closeout following the voluntary termination of enrollment in our NEON-1 and NEON-2 clinical studies in October 2022.

General and Administrative Expense: For the three months ended March 31, 2024, general and administrative expense, inclusive of non-cash expenses, was $7.3 million compared to $5.4 million for the same period in 2023. The increase of $1.9 million was primarily attributable to increases in personnel costs and professional services.

Net Loss: Net loss for the three months ended March 31, 2024, was $17.9 million compared to $13.3 million for the same period in 2023.
