Clinical Trial Summary

This study is a Compassionate clinical study for the treatment of Malignant Tumors. The primary endpoint of the study is to assess the frequency, severity and causality of acute adverse events related to the DaRT treatment. Adverse events will be assessed and graded according to Common Terminology and Criteria for Adverse Events (CTCAE) version 5.0. The secondary endpoint is to assess the tumor response to DaRT treatment assessed using the Response Evaluation Criteria in Solid Tumors (RECIST) (Version 1.1) 3 months after DaRT seed insertion.

Description:

This is an Open label, one arm, prospective study for Compassionate use for the treatment of malignant tumors. The study objectives are to collect data on the safety and efficacy of DaRT among patients who do not fit the entry of existing investigational trials.

The primary endpoint of the study is to assess the frequency, severity and causality of acute adverse events related to the DaRT treatment. Adverse events will be assessed and graded according to Common Terminology and Criteria for Adverse Events (CTCAE) version 5.0. The secondary endpoint is to assess the tumor response to DaRT treatment assessed using the Response Evaluation Criteria in Solid Tumors (RECIST) (Version 1.1) 3 months after DaRT seed insertion.

• Malignant Tumor
• Neoplasms

Intervention

Device:
• Experimental: DaRT seeds
DaRT source will be inserted using preplanned radiotherapy parameters and reassessed by volumetric imaging 2-3 weeks after placement and then removed. The study objectives are to collect data on the general safety and efficacy of DaRT among patients who do not fit the entry criteria of existing investigational trials.
