|Cancer Pleural Neoplasms||Device: CryoSpray Ablation (TM) System||Phase 4|
|Study Design:||Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
|Official Title:||A Pilot Study of the Safety, Efficacy, and Side Effects of Interventional Cryotherapy for the Eradication of Disease in the Pleural Space ("ICE PLS")|
- To Reduce Tumor Burden in the Pleural Space, as Determined by Visual Inspection and Biopsy of the Treatment Sites 2-5 Days Post Treatment. Safety Endpoint Clinical and Radiographic Status at 30 Days Post CryoSpray Treatment and Adverse Events. [ Time Frame: 1 year ]
- To Determine if CryoSpray Causes a Pleurodesis Effect. To Determine if CryoSpray Affects Production of Malignant Effusion Within the Treated Pleural Cavity. To Determine if Pleural Cavity Treatment With CryoSpray is Dosimetry Dependent. [ Time Frame: 1 year ]

Experimental: CryoSpray Ablation (TM) System
subjects will receive cryotherapy using the CryoSpray Ablation (TM) System DOSE: up to 3 cycles of 10-40 second sprays
Device: CryoSpray Ablation (TM) System
Subjects will be treated with spray cryotherapy using the CryoSpray Ablation (TM) System at Day 0 using up to 3 cycles of 10-40 second sprays as the studied dosimetry and will cover the affected area, including the tumor and the parietal pleural surface. If disease exists bilaterally, only one side will be sprayed. Subjects will be assessed 2-5 days from the initial treatment (Day 0) to check for mucosal sloughing, to reassess tumor burden and for additional CSA therapy as needed.
The proposed study is a pilot study consisting of an estimated 10 subjects with biopsy-proven metastatic cancer in the parietal pleural surface treated with CryoSpray at dye marked metastatic foci.
Initial treatment dosimetry will be up to 3 cycles of 10-40 second sprays. If necessary, dosimetry changes may occur after 3 subjects are treated and observed. It is unknown if dosimetry will need to be increased to enhance effectiveness. The PI may increase dosimetry by 1 cycle after each subject is treated and observed as a conservative approach to efficacy determination. If disease exists bilaterally, only one side will be sprayed.
