F-star Therapeutics (“F-star”), a clinical-stage biopharmaceutical company focused on transforming the lives of patients with cancer through the development of innovative tetravalent bispecific (mAb2™) antibodies, today announces that new preclinical data on FS120, a mAb² product candidate targeting OX40 and CD137, will be presented at the Society for Immunotherapy of Cancer (SITC) 2019 Annual Meeting in National Harbor, Maryland, United States, being held from 06 - 10 November 2019.

FS120 is a potentially best-in-class dual agonist that has the potential to overcome cancer resistance by simultaneously engaging OX40 (CD134, TNFRSF4) and CD137 (4-1BB), two receptors found on the surface of tumor-infiltrating lymphocytes. Targeting this class of receptors using bispecific tetravalent binding mobilizes multiple arms of the immune system, which research shows is essential for eliminating tumors. F-star’s preclinical data demonstrated that FS120’s crosslink-dependent approach has the potential to provide therapeutic benefit, for example in combination with checkpoint antagonists, and reverse T cell exhaustion in immunosuppressive tumor environments.

Neil Brewis, CSO of F-star said “Recent clinical trials involving agonist molecules have reported that a meaningful anti-cancer response is often associated with liver toxicity, in line with preclinical observations. F-star’s OX40/CD137 mAb² antibody is showing preclinical evidence that an effective tumor-killing response can be decoupled from liver inflammation. We look forward to progressing FS120 into the clinic as we aim to potentially improve treatment outcomes for patients with difficult-to-treat cancers.”

Some CD137 agonist antibodies have been shown to induce adverse effects either in clinical or in preclinical studies as they constitutively activate T cells and thus release cytotoxic immunity outside of the tumor. In contrast, FS120 is designed to mitigate off-target toxicity through conditional, crosslink-dependent activation upon binding to both OX40 and CD137, which are predominantly present on T cells in the tumor microenvironment.

F-star expects to submit an IND application for FS120 during the fourth quarter of 2019.

Crosslink-independent CD137 agonism is associated with liver inflammation

From Network Automation to Agentic NetOps: NetBrain Sets the Standard for Deploying AI in Network Operations29.5.2026 16:00:00 EEST | Press release

NetBrain Technologies, Inc. today announced major new platform features that advance Agentic NetOps from an emerging category to operational reality. NetBrain's clients are already deploying agents that are diagnosing and remediating issues across complex multi-vendor enterprise networks. These new features further extend the platform with new agent tooling, cross-domain context, and open interfaces for the broader agentic enterprise. Early customer outcomes show the magnitude of the shift: A leading health insurer used NetBrain's Deep Diagnosis agent to diagnose and resolve a weeks old VPN connectivity issue in under five minutes. A large manufacturer resolved a critical device issue with a single prompt, isolating the root cause across the network path in under 20 minutes, saving hundreds of hours of engineer time, shrinking MTTR by more than 95%. A global telecommunications firm found NetBrain's context-grounded agents outperformed a stand-alone frontier LLM on a persistent firewall

Adtran resolves long-running patent litigation, reinforcing commitment to defend innovation29.5.2026 15:00:00 EEST | Press release

Adtran today announced it has resolved a patent litigation matter, resulting in a full settlement and dismissal of all claims with prejudice. The case, initiated in 2020 by a non-practicing entity asserting five patents, was transferred to the US District Court for the Northern District of Alabama in 2021 following a successful motion by Adtran. Adtran subsequently filed counterclaims, including bad-faith patent assertion under Alabama statutory law. The settlement includes payment to Adtran to resolve its counterclaims. Terms of the agreement remain confidential. “This outcome reflects a disciplined and consistent approach to protecting our innovation and our customers,” said Justin Ferguson, SVP and general counsel at Adtran. “We take all claims seriously, but we will not hesitate to defend ourselves when assertions lack merit. Situations like this place unnecessary strain on technology providers and divert resources from advancing networks and services. By advancing our counterclaim
