  Purpose

This is a multi-center, open-label, non-controlled Pilot Study. Approximately 24 patients will be assigned to one of 3 treatment groups (8 patients each group). Patients in each group will receive 2, 4, and 6 (3 followed by a retreatment of 3) subsegmental treatments, respectively. All patients will receive treatment in a single lung under conscious sedation or general anesthesia. Patients will be followed for 24 weeks after completion of PLVR treatment(s). Upon completion of 12-week follow-up, all safety and efficacy data will be analyzed to determine an effective treatment dose. Thereafter, Group 1 patients may elect to be retreated at additional sites so that their total dose received is consistent with the effective dose. All study patients will receive standard medical therapy in addition to PLVR.

Primary Outcome Measures:
  • Change in the ratio of Residual Volume (RV) to Total Lung Capacity (TLC) [ Time Frame: 12 and 24 weeks following treatment ] [ Designated as safety issue: No ]
    Change from baseline in RV/TLC ratio at 12 and 24 weeks following treatment


Secondary Outcome Measures:
  • Change in Forced Expiratory Volume in 1 Second (FEV1) [ Time Frame: 12 and 24 weeks following treatment ] [ Designated as safety issue: No ]
    o Change from baseline in FEV1 (post bronchodilator) at 12 and 24 weeks following treatment

  • Change in Forced Vital Capacity (FVC) [ Time Frame: 12 and 24 weeks following treatment ] [ Designated as safety issue: No ]
    Change from baseline in FVC (post bronchodilator) at 12 and 24 weeks following treatment

  • Change in Diffusing Capacity of the Lung for Carbon Monoxide (DLco) [ Time Frame: 12 and 24 weeks following treatment ] [ Designated as safety issue: No ]
    Change from baseline in DLco at 12 and 24 weeks following treatment

  • Change in Medical Research Council Dyspnea (MRCD) score [ Time Frame: 12 and 24 weeks following treatment ] [ Designated as safety issue: No ]
    Change from baseline in MRCD score at 12 and 24 weeks

  • Change in distance walked in six minutes [ Time Frame: 12 and 24 weeks following treatment ] [ Designated as safety issue: No ]
    Change from baseline at 12 and 248 weeks in 6 Minutes Walk Test (6MWT)

  • Change in St. George's Respiratory Questionnaire (SGRQ) domain score [ Time Frame: 12 and 24 weeks following treatment ] [ Designated as safety issue: No ]
    Change from baseline in disease-specific health related quality of life assessment (SGRQ) at 12 and 24 weeks following treatment


Enrollment: 25

Arms Assigned Interventions
Experimental: PLVR Device: Polymeric Lung Volume Reduction System (PLVR)
20ml (each) of polymer will be injected into 2, 3 or 4 subsegments during the first treatment. Eligible patients may have 20ml (each) of polymer will be injected into 2 or 3 subsegments during the second treatment.

  Eligibility

Criteria

Inclusion Criteria:

  • Patients must have a diagnosis of advanced upper lobe predominant (ULP) emphysema or advanced disease in the superior lower lobes as defined by FEV1/FVC <70 % predicted, FEV1 of < 50% predicted, TLC > 100% of predicted, and RV > 135% predicted.
  • Patients must have persistent symptoms despite medical therapy and either not be candidates for Lung Volume Reduction Surgery (LVRS) or have elected not to undergo LVRS.
  • Patients must be > 40 years of age, have symptoms despite medical therapy, and have none of the pre-specified co-morbid conditions that could influence study outcomes or their ability to tolerate bronchoscopy.
