Acusphere (ACUS) Stock Price, News & Analysis

Company Overview

Acusphere, Inc. was a specialty pharmaceutical company focused on developing drug-delivery technologies and pharmaceutical products for cardiovascular, respiratory, and other medical conditions. The company’s work centered on proprietary particle-based formulations intended to improve the delivery, effectiveness, or tolerability of existing therapeutic compounds.

Acusphere’s historical development portfolio included AeroLEF, an inhaled formulation being evaluated for the treatment of acute pain, and AI-700, an inhaled contrast agent investigated for use in the diagnosis of pulmonary embolism. These products were development-stage candidates and were not established as broadly marketed medicines.

The company was based in the United States and conducted its development activities primarily through clinical research and partnerships. Publicly available information about Acusphere’s current operations, leadership, and geographic reach is limited, and the company appears to have significantly reduced its activities after its historical product-development programs.
