Chemoradiation Plus Iparomlimab Consolidation in Older With ESCC

Recruiting now · Phase 2

Conditions studied: Esophageal Cancer

In brief

This study was conducted in elderly (≥70 years old) patients with locally advanced esophageal squamous cell carcinoma (ESCC). Aim to evaluate the efficacy and safety of Iparomlimab consolidation therapy following concurrent chemoradiation with S-1 in elderly patients with unresectable locally advanced ESCC. Concurrent chemoradiation is the standard treatment for elderly esophageal cancer. However, the overall prognosis of patients still needs to be further improved. The emergence of immune checkpoint inhibitors has brought new hope for patients with ESCC. Iparomlimab can target both PD-1 and CTLA-4 immune inhibitory pathways simultaneously. Studies have shown that it can significantly improve the prognosis in the treatment of ESCC and has good tolerability. In elderly patients with ESCC, concurrent chemoradiation may potentially carry the risk of low treatment completion rate and significant toxicity. Therefore, this study aims to explore the efficacy and safety of Iparomlimab consolidation therapy following concurrent chemoradiotherapy in elderly patients with unresectable locally advanced ESCC. In the study, the investigators plan to enroll 52 elderly subjects with locally advanced ESCC. After receiving radiotherapy combined with the S-1 regimen, patients will enter the screening period. The enrolled patients will receive Iparomlimab consolidation therapy for 1 year. The treatment efficacy and safety will be evaluated.

ECOG performance status 0 or 1;
Provide fresh or archived tumour tissue samples within 6 months (fresh samples preferred) for biomarker analysis (e.g.PD-L1). Sample types are formalin-fixed, paraffin-embedded [FFPE] tumour tissue blocks or at least 5 unstained, 3-5 μm thick FFPE tumour tissue sections;

Serum creatinine ≤ 1.5 × ULN or creatinine clearance ≥ 60mL/min;
International normalized ratio (INR) and activated partial thromboplastin time (APTT) ≤ 1.5× ULN (subjects on stable doses of anticoagulation therapy, such as low molecular weight heparin or warfarin, and with INR within the expected therapeutic range of the anticoagulant can be screened);
Documented informed consent.

You may not qualify if…

Participation in a study of an investigational agent or device within 4 weeks before the first dose of study treatment;
Systemic treatment with corticosteroids (>10 mg prednisone equivalent dose per day) or other immunosuppressive agents is required for 2 weeks before the first dose of study treatment(except for the use of corticosteroids for local inflammation of the esophagus and for the prevention of allergy and nausea and vomiting). Other special circumstances need to be communicated to the sponsor. Inhaled or topical steroids and adrenocorticotropic hormone replacement at doses >10mg/day prednisone efficacy dose are permitted if the patient does not have active autoimmune disease;
Received an anti-tumour vaccine or received a live vaccine within 4 weeks before the first dose of study treatment;
Any active autoimmune disease or history of autoimmune disease (e.g., interstitial pneumonitis, uveitis, enteritis, hepatitis, pituitary gland inflammation, vasculitis, myocarditis, nephritis, hyperthyroidism, hypothyroidism); Except for patients with vitiligo or those who had asthma or allergies in childhood but did not need any intervention as adults; patients with autoimmune-mediated hypothyroidism treated with stable doses of thyroid replacement hormone and type I diabetes mellitus treated with stable doses of insulin may be included;
