Detailed Description

  1. STUDY OBJECTIVES AND ENDPOINTS

1.1. Objectives

The primary objective of this study is to evaluate the safety and effectiveness of balloon kyphoplasty treatment for painful, acute, VCFs as compared to standard non-surgical therapy in patients with cancer.

1.2. Primary Endpoint

The primary endpoint of the study is the improvement in functional status, as measured by the Roland-Morris Disability Questionnaire (RDQ) at 1 month. The primary hypothesis of the study is that the mean improvement will be larger in subjects initially assigned to management with balloon kyphoplasty. Note that all subjects will undergo 12 months of follow-up after initial treatment assignment.

1.3. Secondary Endpoints

The following secondary endpoints will also be examined. Comparisons will be made at each follow-up visit.

Safety:
  • Rate of study treatment-related adverse events

  • Change in neurological status

Clinical:
  • Change in functional status as assessed with Karnofsky Performance Scale

  • Change in quality of life as assessed by the SF-36v2™ Health Survey

  • Change in back pain, as measured by a 10-point Numerical Rating Scale (NRS)

  • Change in back-pain analgesics used

  • Change in ambulation status

  • Changes in activities of daily living

  • Time to treatment failure

Radiographic:
  • Change in spinal deformity, defined as the degree of spine angulation as assessed by an independent radiologist at the core laboratory

  • Rate of subsequent vertebral body fractures, as assessed by independent radiologists at the core lab

In each case, the study hypothesis is that treatment with balloon kyphoplasty will result in an improvement in clinical or radiographic outcomes compared to baseline and compared to non-surgical treatment, with a preservation of outcomes in long-term follow-up.

      The full scale name is the Roland-Morris Disability Questionnaire; it is a validated measure of physical disability due to back pain. The best score is 0 (no disability) and worst is 24 (maximum disability)

    Secondary Outcome Measures

    1. Change in Roland-Morris Disability Questionnaire Score [Baseline, 1 month, 3 months, 6 months, and 12 months]

      Roland-Morris Disability Questionnaire (RMDQ) was used to assess the physical disability due to back pain. The best score is 0 (no disability) and worst is 24 (maximum disability).

    2. Change in Functional Status Assessed With the Karnofsky Performance Scale [Baseline and 1 month]

      The Karnofsky Performance Scale rates a patient on an 11-step scale from 0 (dead) to 100 (normal, no complaints, no evidence of disease).

    3. Change in Functional Status Assessed With the Karnofsky Performance Scale [Baseline, 1 month, 3 months, 6 months, and 12 months]

      The Karnofsky Performance Scale rates a patient on an 11-step scale from 0 (dead) to 100 (normal, no complaints, no evidence of disease).

    4. Change in Back Pain [Baseline and 1 month]

      Back pain was assessed on a 10-point Numerical Rating Scale (NRS) from 0 (no pain) to 10 (worst possible pain).

    5. Change in Back Pain [Baseline, 1 month, 3 months, 6 months, and 12 months]

      Back pain was assessed on a NRS from 0 (no pain) to 10 (worst possible pain).

    6. Change in Quality of Life. [Baseline and 1 month]

      The SF-36 was used to assess quality of life. The SF-36 results were summarized into two components, a physical component summary score (PCS) (0-100) and a mental component summary score (MCS) (0-100). The higher the score, the better the quality of life.

    7. Change in Quality of Life [Baseline, 1 month, 3 months, 6 months, and 12 months]

    Study Results

    Participant Flow

    Recruitment Details Of 134 enrolled subjects, 70 were randomized to Balloon Kyphoplasty and 64 to non-surgical management (NSM). Two of the subjects who were randomized to Balloon Kyphoplasty and 3 of the subjects who were randomized to NSM were excluded from the mITT and PP Populations, because they terminated in a few days of enrolment and had no treatment.
    Pre-assignment Detail Crossover from the NSM group to Balloon Kyphoplasty group was permitted after completion of the 1-month evaluation.
    Arm/Group Title Balloon Kyphoplasty Non-surgical Management Crossover
    Arm/Group Description The subjects assigned to this group have undergone the treatment with Balloon Kyphoplasty for their painful VCFs. The subjects in this group have undergone the non-operative treatments aimed at alleviation of back pain and restoration of decreased function associated with VCFs.

    Outcome Measure Data

    Analysis Population Description
    The analysis population was per-protocol analysis, which was based on the treatment that subjects received. Of 61 subjects randomized into NSM group, 38 subjects crossed over from NSM to Kyphoplasty after the 1-month visit, and 23 subjects remained in NSM group.
    Arm/Group Title Balloon Kyphoplasty Non Surgical Management Crossover
    Arm/Group Description The subjects assigned to this group have undergone the treatment with Balloon Kyphoplasty for their painful VCFs. The subjects in this group have undergone the non-operative treatments aimed at alleviation of back pain and restoration of decreased function associated with VCFs. Subjects in this group were randomized to NSM, then, crossed over to Balloon Kyphoplasty after completion of the 1-month evaluation in NSM group.
