In the evolving landscape of drug discovery and new design, scientists and pharmaceutical innovators ­continually strive to develop therapies that are both highly ­selective and clinically effective, while addressing targets ­previously deemed “undruggable”. In recent years, macrocycles – a class of large, ring-shaped molecules – have emerged as a compelling solution at the crossroads between ­traditional small molecules and large biologics, offering a blend of high specificity, rich chemical diversity and promising pharma­cological profiles.

Basel-based Windward Bio did it again and has raised another three-digit millions – $165 million to be exact – to advance a pipeline of long-acting immunology therapies—much of it sourced through in-licensing deals with Chinese partners. Its lead candidate, WIN378, is moving into Phase III, with first clinical readouts expected from 2026.

Cytospire Therapeutics has raised a £61 million (€71 million) Series A round, positioning the British biotech to advance pan-gamma-delta T-cell engagers (TCEs) into cancer clinical trials.

UCB Candid Bio acquisition

Belgian biopharma UCB has moved quickly from testing the waters in autoimmune T-cell engagers to making one of the largest bets yet on the modality, agreeing to acquire San Diego-based Candid Therapeutics for up to US$2.2bn.
