Checkpoint Inhibitor Combinations Therapy as First Line for Inoperable Lung Cancer Via IT

Официальное название

Intra-tumor Delivery of Double Checkpoint Inhibitors, Chemodrug, and/or Bevacizumab Therapy as First Line for Inoperable Lung Cancer

Обзор

This trial is designed to investigate the safety, response rates and survival outcomes of patients with inoperable lung cancer by infusion of CTLA4, PD1 and PDL1 antibodies combination with chemodrug or/and bevacizumab through intra-tumor (IT).

Подробное описание

Antibodies against CTLA4, PD1 and PDL1 are representative drugs for the check-points inhibitory agents, and their clinical indications have been approved in various types of tumors, including advanced melanoma, non-small cell lung cancer, renal cell carcinoma, and classical Hodgkin's lymphoma and late recurrent head and neck squamous cell carcinoma patients, et al. Those drugs are regularly systemically administrated by vein infusion, however, local delivery of those drugs via interventional radiology technique including trans-artery or intra-tumor injection may increase the local drug concentration of the tumor, improve the efficacy, and reduce systemic adverse reactions. CTLA4 antibody ipilimumab has been widely effectively using to combine with PD1 or PDL1 antibody and this study is to combine ipilimumab and PD1 antibody or PDL1 antibody, so called double checkpoint inhibitors combination therapy, as first line for inoperable lung cancer via intra-tumor admistration. To the investigator's knowledge, no studies have been developed on the safety, efficacy and survival benefit of the double checkpoint inhibitors combination therapy for cancer patients as first line via intra-tumor delivery.

This phase II clinical trial is designed to assess the safety and survival benefit of ipilimumab and pembrolizumab or durvalumab combination with or without chemodrug or bevacizumab as first line therapy on patients with inoperable lung cancer, including PFS, ORR, DCR, and median survival time.

Вмешательства

• Препарат ipilimumab+pembrolizumab or ipilimumab+durvalumab, idarubicin, bevacizumab
  This study has 3 subgroups: Arm 1. Ipilimumab +pembrolizumab or Ipilimumab +durvalumab is administrated with a total dose of 1-2mg/kg via intra-tumor fine needle injection in 10 min, every 3 weeks. Arm 2. Ipilimumab +pembrolizumab or Ipilimumab +durvalumab combined with idarubicin is administrated via intra-tumor fine needle injection in 15 min, every 3 weeks. Arm 3. Ipilimumab +pembrolizumab or Ipilimumab +durvalumab combined with idarubicin plus bevacizumab is administrated via intra-tumor
