**Summary**
Arecor Therapeutics plc, a biopharmaceutical company focused on diabetes and cardiometabolic diseases, announced two significant strategic developments on September 25, 2025
1. **Co-Development Agreement with Sequel Med Tech:**
Arecor has partnered with Sequel Med Tech, LLC, a US-based insulin pump device company, to co-develop AT278 (500U/mL), an ultra-concentrated and ultra-rapid acting insulin. The collaboration aims to integrate AT278 with Sequels twiistâ„¢ Automated Insulin Delivery (AID) system, powered by Tidepool. Both companies will jointly fund up to $1.3 million each for Phase 2 trial-enabling development work, including regulatory filings, manufacturing, and system compatibility. The goal is to achieve IND (Investigational New Drug) filing by 1H 2026 and initiate a pivotal Phase 2 trial in 2H 2026. The partnership also includes a broader co-development and commercialization agreement for future phases. This collaboration addresses unmet needs in diabetes management, particularly for patients requiring high daily insulin doses and extended-wear devices.
2. **Monetisation Deal with Ligand Pharmaceuticals:**
Arecor secured up to $11 million in non-dilutive funding by selling royalty rights related to AT220 (an Arestat®-enhanced biosimilar) and milestone/technology access fees for AT292 (now Sanofis Efdoralprin alfa) to Ligand Pharmaceuticals. The deal includes a $7 million upfront payment and $4 million in milestone payments, with $1 million expected in 2026. This funding extends Arecors cash runway to 1H 2027, enabling accelerated clinical development of AT278 without shareholder dilution.
**Key Highlights**
AT278 is positioned as the only ultra-concentrated, ultra-rapid insulin in development, designed for next-generation AID systems.
The Sequel partnership aligns with Arecors focus on transformative drug delivery solutions, leveraging Sequels advanced twiistâ„¢ system for precise insulin dosing.
The Ligand deal strengthens Arecors financial position, supporting R&D priorities like AT278 and oral peptide delivery platforms.
The total addressable US insulin market for AT278 is estimated at $2.9 billion, with additional global commercialization potential.
These agreements mark significant milestones for Arecor, enhancing its pipeline, financial stability, and market opportunities in diabetes care.
