Data Provenance | Financial Data Quantitative Analysis Analysis: Mar 17, 2026

What Is the Investment Thesis for ALPN?

As of Mar 17, 2026 — figures reflect the data available on that date.

Alpine Immune Sciences presents a notable research candidate within the biotechnology sector. The company's innovative pipeline, particularly ALPN-101, ALPN-202, and ALPN-303, targets significant unmet needs in autoimmune diseases and cancer. The collaboration with AbbVie for ALPN-101 validates the potential of Alpine's platform and provides financial resources for further development. Key value drivers include successful clinical trial outcomes for its lead programs, potential regulatory approvals, and expansion of its pipeline through internal research and strategic partnerships. A potential risk lies in the inherent uncertainty of clinical development and regulatory approval processes. The company's negative profit margin of -54.7% indicates that it is not currently profitable and relies on external funding or partnership revenue. Continued progress in clinical trials and strategic collaborations are essential for realizing the company's long-term value.
