US FDA Approval of IND for CTLA-4 Antibody YH001 for the Treatment of Front-line Sarcoma Patients in Combination with Envafolimab
14.9.2022 18:51:00 EEST | Business Wire | Press release
Biocytogen Pharmaceuticals (Beijing) Co., Ltd. ("Biocytogen") and TRACON Pharmaceuticals, Inc. (Nasdaq: TCON), today jointly announced that the U.S. Food and Drug Administration (FDA) has approved the Investigational New Drug (IND) application for the initiation of a Phase 1/2 clinical study of YH001 in combination with envafolimab and doxorubicin for the treatment of sarcoma patients, including patients who have not received prior therapy.
The Phase 1/2 trial will assess the safety and efficacy of YH001 and envafolimab in patients with the rare sarcoma subtypes of alveolar soft part sarcoma and chondrosarcoma and assess the safety and efficacy of the combination of YH001, envafolimab and doxorubicin in the common sarcoma subtypes of leiomyosarcoma and dedifferentiated liposarcoma.
“YH001 was discovered using Biocytogen’s evidence-based in vivo drug efficacy screening platform and has demonstrated a favorable safety profile and promising anti-tumor activity in combination with a PD-1 antibody in an earlier phase 1 clinical study,” said Rong Chen, M.D., Ph.D., VP of Biocytogen, CEO and CMO of Eucure Biopharma. “As an antibody targeting the validated checkpoint CTLA-4, YH001 is expected to play a very important role in immune-oncology therapy. We are glad to learn that the combination therapy of YH001 + envafolimab and doxorubicin received IND approval by the FDA.”
“We are pleased to receive approval from the FDA to initiate our triplet combination therapy study in sarcoma, which includes our potentially best-in-class CTLA-4 antibody YH001 and the only subcutaneous checkpoint inhibitor approved anywhere in the world, envafolimab,” said Charles Theuer, M.D., Ph.D., TRACON’s Chief Executive Officer. “We look forward to enrolling patients in this study and giving patients additional options for their sarcoma treatment.”
About YH001
YH001 is an IgG1 antibody targeting CTLA-4 that was invented by Biocytogen, the parent company of Eucure Biopharma, and licensed by TRACON. YH001 has shown enhanced antibody dependent cellular cytotoxicity (ADCC) and complement dependent cytotoxicity (CDC) in vitro when compared with ipilimumab. In preclinical studies YH001 demonstrated superior T cell activation and superior tumor growth inhibition activity compared to ipilimumab as a single agent and when combined with a PD-(L)1 antibody in human transgenic mouse tumor models. In these models, single agent YH001 depleted regulatory T cells and increased CD8+ T cells in tumor tissue. YH001 has been dosed as a single agent in a Phase 1 trial in China (NCT04699929) and in combination with the PD-1 antibody toripalimab in a Phase 1 trial in Australia (NCT04357756).

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.

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
