What are the financial terms of the agreement: The detailed financial terms of the agreement were not disclosed. As per the publicly available details, ADC Therapeutics will cover all Avacta’s costs during the project. The firm also has the right to obtain exclusive licenses to the Affimer proteins for clinical development and commercialization.
What are Affimers: Affimers are small proteins that target and bind molecules on cellular surfaces in a manner analogous to monoclonal antibodies. The key difference is that affimers are optimized to enhance their structural stability. They are also more resistant than mAbs to changes in environmental pH and temperature.
How many of the ADCs in development have pyrrolobenzodiazepine (PBD) as warhead: Pyrrolobenzodiazepines are a class of compounds that kill cells by binding their DNA and interfering with replication. In nature, they are made by a group of bacteria known as actinomycetes. Of the ADCs in development, around 12% have PBD as the payload / warhead.
With such a strong development pipeline, the overall ADC therapeutics market is projected to be worth $15 billion by 2030, growing at a CAGR of over 20%. This fast-growing market offers immense opportunities for contract manufacturers, service providers, and technology developers.
