Summary:

      This is intended to be an initial "proof-of-concept" study to show feasibility, validate
      assays and approaches, and explore dosing and safety of belimumab in pulmonary emphysema
      patients who have clinically relevant (and quantifiable) autoimmune responses. The primary
      goal is to determine effects of belimumab on levels of autoantibodies against glucose
      regulated protein 78 (GRP78) among patients with pulmonary emphysema attributable to
      cigarette smoking. The investigators hypothesize that belimumab treatment will safely reduce
      circulating levels of autoantibodies that are associated with emphysema, and comorbidities of
      this lung disease, including atherosclerosis.
    

Eligibility criteria:

        Inclusion Criteria:

          1. A history of past tobacco smoking (>10 pack years), but quit for >6 months at the time
             of enrollment. Smoking cessation will be confirmed by serum cotinine assays.

          2. Pulmonary emphysema per chest CT scans (F950>5%). About 60% of COPD patients followed
             in the LHC registry meet these criteria.6 Chest CTs are routine, standard of practice
             evaluations for patients with COPD, so no new radiographic studies will be necessary
             for this project.

          3. Ability and willingness to give informed consent.

          4. Plasma anti-GRP78 binding IgG >mean values in former smokers with no lung disease
             (standardized OD >0.390) (hence this is a "personalized medicine" approach). Of the
             330 emphysema subjects assayed for anti-GRP78 to date, 111 (67%) met this criterion.

          5. Age 40-75 y.o. COPD is a disease of older individuals.

        Exclusion Criteria:

          1. History of prior acute COPD exacerbations or no more than one moderate exacerbation in
             the last year and no exacerbations four months prior to enrollment. A past history of
             an acute exacerbation is the single biggest risk for recurrence.36 Exclusion of these
             higher-risk subjects will minimize drop-outs.

          2. Oral steroids or cellular immunosuppressant use (e.g., cyclophosphamide) within 6
             months.

          3. History or clinical or laboratory evidence of other autoimmune syndromes.

          4. Inability or unwillingness to complete the treatment and surveillance protocols.

          5. Eligible for lung transplant at time of enrollment. This exclusion will mitigate any
             potential, however slight, that a patient could be rejected for transplantation due to
             surgeon concerns about this novel therapy (and will also obviate early drop-outs due
             to transplantation).

          6. History of malignant neoplasm within the last 5 years.

          7. Evidence of serious suicide risk including any history of suicidal behavior in the
             last 6 months and/or any suicidal ideation in the last 2 months or those, in the
             investigator's judgment, pose a significant suicide risk.

          8. History of a primary immunodeficiency.

          9. Significant IgG deficiency (IgG level < 400 mg/dL).

         10. Have an IgA deficiency (IgA level < 10 mg/dL).

         11. Currently on any suppressive therapy for a chronic infection (such as tuberculosis,
             pneumocystis, cytomegalovirus, herpes simplex virus, herpes zoster or atypical
             mycobacteria).

         12. Hospitalization for treatment of infection within 60 days of Day 0.

         13. Use of parenteral (IV or IM) antibiotics (antibacterials, antivirals, anti-fungals, or
             anti parasitic agents) within 60 days of Day 0.

         14. Current drug or alcohol abuse or dependence, or a history of drug or alcohol abuse or
             dependence within 365 days prior to Day 0.

         15. History of a positive HIV test or positive screening test for HIV.

         16. Serologic evidence of current or past Hepatitis B (HB) or Hepatitis C (HC) infection
             based on positive tests for HBsAg or HBcAb, or HCAb.

         17. History of an anaphylactic reaction to parenteral administration of contrast agents,
             human or murine proteins or monoclonal antibodies.

         18. Any other clinically significant abnormal laboratory value in the opinion of the
             investigator.

         19. Any intercurrent significant medical or psychiatric illness that the investigator
             considers would make the candidate unsuitable for the study.

         20. Women of Child Bearing Potential (WCBP) must have a negative serum pregnancy test
             (either blood or urine) at screening, and agree to 1 of the following:

             Complete abstinence from intercourse from 2 weeks prior to administration of the 1st
             dose of study agent until 16 weeks after the last dose of study agent (Sexual
             inactivity by abstinence must be consistent with the preferred and usual lifestyle of
             the subject. Periodic abstinence (e.g. calendar, ovulation, symptothermal,
             post-ovulation methods) and withdrawal are not acceptable methods of contraception)

             OR

             Consistent and correct use of 1 of the following acceptable methods of birth control
             for 1 month prior to the start of the study agent, during the study, and 16 weeks
             after the last dose of study agent:

                  the female subject's entry into the study, and this male is the sole partner for
                  that subject. For this definition, "documented" refers to the outcome of the
                  investigator's/designee's medical examination of the subject or review of the
                  subject's medical history for study eligibility, as obtained via a verbal
                  interview with the subject or from the subject's medical records
