By GlobalDataNew ‘heavy chain only’ antibodies, nearly half the size of a standard IgG, are created using HCAb’s technology.
These antibodies possess IgG-like PK characteristics and Fc-domain works without requiring further engineering or humanisation.
The latest agreement comes after Nona entered a licence and partnership agreement with Moderna for nucleic acid-based immunotherapies for chosen oncology targets.
Under the partnership deal, Nona was entitled to receive an upfront payment as well as payments on meeting specific regulatory, development and sales-based milestones and tiered royalty payments.
In April this year, Dragonfly and AbbVie expanded their research collaboration to discover and develop the new immunotherapies of the former for new targets in fibrotic and autoimmune diseases.
