Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 40 to 75 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • 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.
  • 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.
  • Ability and willingness to give informed consent.
  • 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.
  • Age 40-75 y.o. COPD is a disease of older individuals.

Who cannot join

  • 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.
  • Oral steroids or cellular immunosuppressant use (e.g., cyclophosphamide) within 6 months.
  • History or clinical or laboratory evidence of other autoimmune syndromes.
  • Inability or unwillingness to complete the treatment and surveillance protocols.
  • 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).
  • History of malignant neoplasm within the last 5 years.
Show all 41Show fewer
  • 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.
  • History of a primary immunodeficiency.
  • Significant IgG deficiency (IgG level < 400 mg/dL).
  • Have an IgA deficiency (IgA level < 10 mg/dL).
  • Currently on any suppressive therapy for a chronic infection (such as tuberculosis, pneumocystis, cytomegalovirus, herpes simplex virus, herpes zoster or atypical mycobacteria).
  • Hospitalization for treatment of infection within 60 days of Day 0.
  • Use of parenteral (IV or IM) antibiotics (antibacterials, antivirals, anti-fungals, or anti parasitic agents) within 60 days of Day 0.
  • Current drug or alcohol abuse or dependence, or a history of drug or alcohol abuse or dependence within 365 days prior to Day 0.
  • History of a positive HIV test or positive screening test for HIV.
  • Serologic evidence of current or past Hepatitis B (HB) or Hepatitis C (HC) infection based on positive tests for HBsAg or HBcAb, or HCAb.
  • History of an anaphylactic reaction to parenteral administration of contrast agents, human or murine proteins or monoclonal antibodies.
  • Any other clinically significant abnormal laboratory value in the opinion of the investigator.
  • Any intercurrent significant medical or psychiatric illness that the investigator considers would make the candidate unsuitable for the study.
  • 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:
  • Oral contraceptive, either combined or progestogen alone
  • Injectable progestogen
  • Implants of levonorgestrel or etonogestrel
  • Estrogenic vaginal ring
  • Percutaneous contraceptive patches
  • Intrauterine device (IUD) or intrauterine system (IUS) with <1% failure rate as stated in the product label
  • Male partner sterilization (vasectomy with documentation of azoospermia) prior to 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
  • Double barrier method: condom and occlusive cap (diaphragm or cervical/vault caps) plus spermicidal agent (foam/gel/film/cream/suppository)
  • Use of Excluded Medications:
  • Anti-B-cell therapy:

About this study

Official title: Proof-of-concept Randomized, Double-blind, Phase IIa Study to Show Feasibility, Validate Assays and Approaches, and Explore Dosing and Safety of Belimumab in Pulmonary Emphysema Patients

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.

Read the detailed description

Specific Aim 1: To conduct a double-blind, Phase IIa trial, in which 18 former smokers with pulmonary emphysema (per chest CT scans), and circulating anti-GRP78 autoantibody levels >mean normal values (by ELISA), will be randomized 2:1 to belimumab vs. placebo. Subjects will receive 8 infusions of either belimumab or placebo over a 6 month interval. Plasma anti-GRP78 will be measured pre-treatment, and at 1, 3, 5, and 7 months. The investigators hypothesize belimumab therapy will more effectively reduce anti-GRP78 IgG autoantibodies, the primary endpoint of this trial, compared to placebo.

Specific Aim 2: To determine effects of the belimumab therapy on secondary endpoints (at the times detailed for Aim 1) that include levels of pneumococcal-binding antibodies (by ELISA), circulating B-cell numbers and phenotypes (by flow cytometry), and the rate and severity of adverse events (AE) at any time during treatment. The investigators hypothesize belimumab will have dose-related effects on B-cell numbers and their differentiation, while minimally reducing host defense antibodies, and will also have an acceptable AE profile.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Change of Circulating Anti-GRP78 IgG Levels

    Anti-GRP78 IgG is a clinically relevant surrogate biomarker of autoimmunity in pulmonary emphysema patients who have clinically relevant (and quantifiable) autoimmune responses

    Measured: Plasma concentrations of the anti-GRP78 autoantibodies will be measured pre-treatment and at end of treatment at 210 days (or when subject withdraws)

Secondary outcomes (3)
  1. Percent Change of Pneumococcal Polysaccharide-binding Antibodies

    Treatment effects on concentrations of pneumococcal polysaccharide-binding antibodies by ELISA

    Measured: Prior to treatment and at end of treatment on day 210 (or the conclusion of treatment if subject withdraws)

  2. Percent Change of Circulating B-cells

    Treatment effect on relative percentages of circulating B-cells (CD20+) by flow cytometry

    Measured: Prior to treatment, and at treatment end on day 210 or when subject participation is terminated

  3. Adverse Events

    Adverse events will be evaluated according to criteria outlined in the National Cancer Institure (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4.0.

    Measured: Study start to completion (7 months)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Belimumab in people with Chronic Obstructive Pulmonary Disease and Emphysema, run by University of Alabama at Birmingham at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 41 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Jul 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent Change of Circulating Anti-GRP78 IgG Levels (time frame: Plasma concentrations of the anti-GRP78 autoantibodies will be measured pre-treatment and at end of treatment at 210 days (or when subject withdraws)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jul 2023.
