About Allegria Therapeutics

Allegria Therapeutics, a Swiss biotechnology firm established in Basel in 2023, is focused on developing treatments for mast cell-mediated diseases. The company was founded by Forty51 Ventures, an early-stage investor and company builder, which also provided the initial seed funding of USD 3.5 million. The firm is led by co-founder and CEO, Dr. Maria van Dongen, a seasoned R&D leader with over 25 years of experience in the pharmaceutical and biotech sectors, including roles at Johnson & Johnson where she facilitated external partnerships and led projects in drug discovery.

Read full description

The company's core business revolves around creating a portfolio of proprietary therapeutic approaches that selectively modulate mast cells. These cells are key mediators of allergies and inflammatory diseases, conditions that represent a significant and growing global health burden with limited and often ineffective treatment options. Allegria Therapeutics is concentrating its research and development on conditions such as chronic urticaria, mast-cell-driven syndromes, and food allergies. The business model is centered on advancing its therapeutic candidates to the clinical proof-of-concept stage, with the ultimate goal of forming partnerships with larger pharmaceutical companies for full-scale development and global market access.

Allegria's therapeutic strategy is to directly and selectively target mast cells, aiming for improved efficacy and safety compared to existing treatments that often target immunoglobulin E (IgE) and histamine. To achieve this, the company collaborates with prominent academic partners in mast cell biology and drug discovery, including Prof. Marcus Maurer of the Institute for Allergy Research at Berlin's Charité and Dr. Philipp Starkl of the Medical University of Vienna. The initial seed funding is being used to advance a discovery portfolio that currently consists of three distinct programs. This targeted approach to mast cell modulation has the potential to address the unmet needs of patients suffering from these debilitating conditions.
