OncoMatch/Clinical Trials/NCT06493552
Modular Trial of sEphB4-HSA in EphrinB2-High Solid Tumors
Is NCT06493552 recruiting? Yes, currently enrolling (May 2026). This Phase 2/3 trial studies multiple treatments for muscle-invasive bladder carcinoma.
Treatment: SEphB4-HSA · Pembrolizumab · Gemcitabine · Cisplatin · Enfortumab vedotin — Patients with solid tumors that have high expression levels of EphrinB2 are treated with regimens that include EphrinB2 inhibitor, sEphB4-HSA. The primary objective of this study is to demonstrate additive therapeutic benefit for sEphB4-HSA. The secondary objectives are to determine whether the sEphB4-HSA containing regimen is safe and whether the oncological endpoints of importance in each cohort improve as a result of treatment with sEphB4-HSA containing regimen relative to a predefined threshold or to a control arm in the cohort where available. Treatment continues until progression of disease or unacceptable toxicities arise.
