Cryoablation Combined with Sintilimab Plus Lenvatinib in Previously Treated Unresectable Liver Metastasis from Solid Tumors

A Phase II Study of Cryoablation Combined with Sintilimab Plus Lenvatinib in Previously Treated Unresectable Liver Metastasis from Solid Tumors (CASTLE-04)

The objective of this study is to evaluate the efficacy and safety of cryoablation combined with Sintilimab plus lenvatinib for patients with unresectable liver metastasis, who had progressed after, or were refractory to first- or later-line therapy.

Study Overview

• Status: Recruiting
• Conditions: Liver Metastasis
• Intervention / Treatment: Drug: Sintilimab; Drug: Lenvatinib; Drug: Cryoablation

Detailed Description

Recent studies have suggested that local destruction of tumor tissue by cryoablation induced activation and maturation of dendritic cells and tumor-specific T cells by cross-presentation of tumor antigens. While pd-1 blocking antibody interferes with PD-1 mediated T-cell regulatory signaling. And combination of pd-1 blocking antibody plus lenvatinib showed increased ORR in many type of solid tumors. Therefore, the objective of this study is to evaluate the efficacy and safety of cryoablation combined with Sintilimab plus lenvatinib in previously treated unresectable liver metastasis from solid tumors.

• Immunocompromised patients, e.g. patients who are known to be serologically positive for human immunodeficiency virus (HIV).
• Participation in another clinical study with an investigational product during the last 30 days before inclusion or 7 half-lifes of previously used trial medication, whichever is longer.

• Any condition or comorbidity that, in the opinion of the investigator, would interfere with evaluation of study Treatment or interpretation of patient safety or study results, including but not limited to:

  8. Has an active autoimmune disease requiring systemic treatment within the past 3 months or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents. Exceptions: Subjects with vitiligo, hypothyroidism, diabetes mellitus type I or resolved childhood asthma/atopy are an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Subjects with Hashimoto thyroiditis, hypothyroidism stable on hormone replacement or psoriasis not requiring treatment are not excluded from the study.

Intervention / Treatment

Experimental: Cryoablation in combination with Sintilimab plus lenvatinib

Drug: Sintilimab; Sintilimab plus lenvatinib will be initiated on day 14 after cryoablation. Sintilimab will be administered at 200 mg i.v. every 3 weeks.; Drug: Lenvatinib; Sintilimab plus lenvatinib will be initiated on day 14 after cryoablation. Lenvatinib (bodyweight ≥ 60 kg, 12 mg; < 60 kg, 8 mg) was given orally daily every 3 weeks until documented disease progression, development of unacceptable toxicity, participant request, or withdrawal of consent.; Drug: Cryoablation; Cryoablation treatment starts at day 0. Cryoablation will be performed with a two-cycle freeze-thaw phase protocol; US or non-contrast CT images will be obtained to visualize the evolving ablation zone
