Cybersecurity Risk Management, Strategy, and Governance [Line Items] |
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | Item 1C. Cybersecurity. Cybersecurity Risk Management and Strategy We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity, and availability of our critical systems and information. We design and assess our program based on the Information Systems Audit and Control Association’s Control Objectives for Information Technologies framework and National Institute of Standards and Technology cybersecurity framework, as well as threat trends identified by multiple external and internal cybersecurity intelligence reports. We contract with external firms to assess our cybersecurity controls. We have processes in place to identify and evaluate risks associated with third party vendors and suppliers. In addition, we have systems in place to maintain business continuity and disaster recovery. Some or all of this work is done through our services agreement with Agenus. To date, we have not experienced any material cybersecurity incidents. We describe whether and how risks from cybersecurity threats are reasonably likely to affect our business, results of operations and financial condition, under the heading “Our internal computer systems, or those of our third-party vendors, collaborators or other contractors or consultants, may fail or suffer security breaches, which could result in a material disruption of our product development programs, compromise sensitive information related to our business or prevent us from accessing critical information, potentially exposing us to liability or otherwise adversely affecting our business” included as part of our Item 1A.
