Conditions: Chronic Obstructive Pulmonary Disease Emphysema
Keywords: COPD belimumab biologic agent GRP78
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 17
Healthy volunteers: no

Brief 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.

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.

Arms:
arm 1: Subjects randomized to the experimental treatment arm will receive i.v. administrations of belimumab (10 mg/kg), consisting of three "loading" doses, two weeks apart, followed by five (5) more monthly infusions. The final assessment will be performed at month 8. arm 2: These subjects will be treated with identically appearing placebo i.v. on the same schedule as the experimental arm subjects (i.e., three "loading" doses, two weeks apart, followed by five more monthly infusions. Again, the final assessment will be performed at month 7 (210+10 days after treatment start).

Interventions: intervention 1: Belimumab intervention 2: Placebo
Intervention descriptions: intervention 1: Belimumab is an anti-BLyS (B-lymphocyte stimulating factor) agent administered by infusion. intervention 2: An identically appearing placebo infusion.

Study Aims: 
 
Specific Aim 1: To conduct a double-blind, Phase II trial, in which 18 former 
smokers with COPD 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 antibodies will be measured pre-treatment, and at 
1, 3, 5, and 7 months.  We 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.   We 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. 
 
Study Design: 
 
 
Following baseline screening assessments, patients that meet all 
inclusion/exclusion criteria will be randomly assigned to receive one of the 
following treatments in a ratio of 2:1: 
 
1.) Arm 1: Belimumab (n = 12).   Subjects randomized to the experimental 
treatment arm will receive i.v. administrations of belimumab (10 mg/kg), 
consisting of three "loading" doses, two weeks apart, followed by five (5) more 
monthly infusions.  The final dose is administered at month 6 with final 
assessment at month 7 and a safety visit at month 10.     
 
2.) Arm 2: Placebo Controls (n = 6).  These subjects will be treated with 
identically appearing placebo i.v. on the same schedule as the experimental 
arm subjects (i.e., three "loading" doses, two weeks apart, followed by five 
more monthly infusions.  Again, the final assessment will be performed at 
month 7 (210+10 days after treatment start).  
 
Planned Sample Size: 
A total of 18 subjects will be enrolled in this trial.  In order to reach the needed 
sample size of 18, twenty-five subjects will be randomized to account for subjects 
who have been withdrawn early due to the current COVID-19 pandemic in order 
to comply with guidance regarding human subjects research conduct and also 
for medical reasons un-related to study drug or study procedures. 
 
Duration of Treatment: 
Six months 
Duration of 
Participation 
Ten months 
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.) Clinical diagnosis of at least moderate COPD as defined by the Global 
Initiative for Obstructive Lung Disease (GOLD) criteria:

a. Post bronchodilator FEV1/FVC < 70%, 
 
 
b. Post bronchodilator FEV1 between 25% and 80% predicted, with or 
without chronic symptoms (i.e., cough, sputum production). 
COPD 
3.)  Ability and willingness to give informed consent.  
 
4.) Levels of plasma autoantibodies against a 15–mer peptide sequence within 
the GRP78 molecule (a.a. 246-260) that are in the upper three quartiles of 
values present in COPD patients.  This epitope will henceforth be denoted as 
GRP78 Peptide 25.  Levels of anti-GRP78 Peptide 25 autoantibodies are 
significantly correlated with carotid artery intimal medial thickness (IMT) among 
COPDpatients.     
 
5.) Age 40-75 y.o. COPD is a disease of older individuals.   
 
Major Exclusion 
Criteria: 
1.) History of more than one moderate (treated as outpatient) or severe 
(requiring hospitalization) acute exacerbation of COPD within the 12 months 
prior to screening or any moderate or severe exacerbation within the 4 months 
prior to screening.  A past history of an acute exacerbation is the single biggest 
risk for recurrence.36 Exclusion of subjects at highest risk 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 
(confirmed by self-report and medical record review).  
 
4.) Inability or unwillingness to complete the treatment and surveillance 
protocols.  
 
5.) Listed 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.) 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 screening. 
 
13.) Use of parenteral (IV or IM) antibiotics (antibacterials, antivirals, anti-
fungals, or anti-parasitic agents) within 60 days of screening. 
 
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 (for compliance 
and safety). 
 
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 urine 
pregnancy test 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:  
 
o Oral contraceptive, either combined or progestogen alone 
o Injectable progestogen  
o Implants of levonorgestrel or etonogestrel 
o Estrogenic vaginal ring 
o Percutaneous contraceptive patches 
o Intrauterine device (IUD) or intrauterine system (IUS) with <1% 
failure rate as stated in the product label

o 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

1.1 OBJECTIVE 
 
The goal of this randomized blinded Phase IIa clinical trial is to begin to determine selected 
effects (and safety) of belimumab therapy in pulmonary COPD patients who have autoantibodies 
with specificities against glucose regulated protein 78 (GRP78).    
 
The information gained in this trial will be invaluable, and enable us, and others, to credibly 
propose a subsequent larger and longer clinical trial, that could more definitively test the effects 
of belimumab on the progression of COPD and atherosclerosis (and perhaps other related 
comorbidities).   
 
 
1.2 SPECIFIC AIMS 
 
Hypothesis: 
 
Our specific study hypothesis is that belimumab treatment will safely reduce circulating levels 
of autoantibodies to GRP78 that have been associated with pulmonary COPD, and 
comorbidities of this lung disease, including atherosclerosis.    
 
Specific Aims: 
 
Specific Aim 1: To conduct a double-blind, Phase II trial, in which 18 former smokers with 
pulmonary COPD (per chest CT scans), and circulating anti-GRP78 autoantibody levels >mean 
normal values (by ELISA), will be randomized 2:1 to belimumab vs. placebo.  Plasma anti-
GRP78 will be measured pre-treatment, and at 1, 3, 5, and 7 months.  We 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 that 
include levels of pneumococcal-binding antibodies (by ELISA), circulating B-cell numbers and 
phenotypes (by flow cytometry), and adverse events (AE).   We hypothesize belimumab will have 
dose-related effects on B-cell numbers and their differentiation, but will minimally reduce host 
defense antibodies, and will have an acceptable adverse event profile. 
 
 
1.3 BACKGROUND 
Chronic obstructive pulmonary disease (COPD), which includes the COPD phenotype of COPD, is 
the third leading cause of death world-wide, and the prevalence (and impact) of these lung disorders 
are increasing.  COPD/COPD directly cause considerable disability and premature deaths.1-3 In 
addition, the systemic manifestations of COPD, such as osteoporosis and atherosclerosis, result in 
considerable additional morbidity and mortality.4-6 Current treatments are nonspecific and have little 
impact on the natural histories of either the lung abnormalities or comorbidities.   
 “Chronic inflammation” has been implicated in the genesis of COPD and the several singular 
comorbidities of this disease, but the causal immunological mechanism(s) have remained enigmatic. 
We, and others, have shown that chronic inflammation in COPD can be mediated by pathogenic 
autoantibodies, autoreactive T-cells, and other immunological abnormalities that parallel features of 
conventional autoimmune syndromes.6,7 Moreover, recent findings (to follow) implicate 
autoimmunity in the genesis and progression of COPD,  and the osteoporosis and 
atherosclerosis that are often associated with this lung disease:

1.4 PRELIMINARY DATA 
We, and now others, have shown that antigen-antibody (immune) and complement complexes, 
which are known to cause severe tissue injuries in SLE and other autoimmune diseases, are also 
near ubiquitous in lungs of patients with severe COPD/COPD.7  We have also shown circulating B-
cells are highly differentiated in COPD, a consequence of repetitive antigen stimulation typically 
seen in patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and other 
autoantibody-mediated disorders.8   
We’ve also reported serum B-lymphocyte stimulating factor (BLyS, aka: B cell activating factor 
or BAFF) concentrations are also abnormally increased in COPD patients (Figure 1).8  We were 
particularly interested in study of this mediator because belimumab, a specific anti-BLyS agent, is 
already available for treatment of SLE.  The adaptation of belimumab therapy for use in 
autoimmune COPD patients is the basis of the current proposal.  Our BLyS findings in COPD 
patients have since been corroborated by at least two other groups.9,10 One of those studies also 
indicated anti-BLyS therapy had favorable effects in a preclinical 
mouse model of COPD.9  
 
 
Figure 1 (right).  Plasma levels of BLyS are greater in COPD 
patients (n=90) than in healthy normal subjects (Nl) (n=53).8 
 
 
We also recently discovered autoantibodies against glucose 
regulated protein 78 (GRP78) are prevalent in patients with COPD 
(Figure 2).6 GRP78 is a heat shock protein, and an autoantigen in 
several other immune disorders.11,12 Intrapulmonary GRP78 is 
upregulated by smoke exposure, viral infections, and various other 
injuries, and this molecule is over-expressed in COPDtous lungs.6 The presence of anti-GRP78 was 
also highly associated with osteoporosis in smokers (Figure 3). 6    
 
 
 
Figure 2 (left). A) Anti-GRP78 autoantibodies detected by Western blots 
were more prevalent in smokers/former smokers with COPD,

Other recent 
findings also show anti-
GRP78 autoantibody levels are predictive of COPD progression (Figure 4).   
The circulating anti-GRP78 autoantibodies in these patients have direct pathogeneic effects that 
can cause or contribute to lung, bone, and other diseases.  In addition to function as an intracellular 
protein chaperone and key component of the unfolded protein response, GRP78 is extracellularly 
exported by stressed cells.11  Extracellular GRP78 acts like a cytokine, binding to and stimulating 
various cell surface receptors that transduce signals on many different cell types. Studies by us, and 
others, show anti-GRP78 autoantibodies can bind and crosslink these cell surface GRP78-
receptor complexes on target cells, including macrophages and osteoclasts (the bone 
correlate of a macrophage), which then increase their productions of pro-inflammatory 
mediators implicated in lung injury and bone resorption.6,12 Anti-GRP78 in patients with RA and 
other immunological diseases also have similar injurious effects.12  
 
 
 
Figure 4 (left). COPD Progression and Anti-GRP78 Autoantibodies. 
Anti-GRP78 autoantibody levels (per ELISA Optical Density [OD]) are 
greater in subjects whose COPD worsens over the next 2 years, per 
serial CT COPD scores.  Shown here are heavy smokers with COPD but 
normal spirometry (denoted as SC in Fig. 2). (Manuscript in preparation).   
 
 
 
 
 
 
Additional preliminary (unpublished) data show anti-
GRP78 autoantibodies from COPD patients bind to primary human endothelial cells that were 
stressed by culturing them in turbulent flow conditions, due to increased translocation of 
GRP78 to the cell surfaces (not shown).   
 
We have recently further refined our immunological studies by testing for autoreactivity against 
individual short peptide sequences within the GRP78 molecule.  Thirty-one (31) different peptides 
within the GRP78 molecule  were selected using an autoantibody epitope prediction algorithm.  
Candidate peptides were then synthesized in vitro, and identities were confirmed by mass 
spectroscopy prior to individual testing in ELISA.  We have found associations between carotid artery 
IMT in COPD patients and circulating levels of autoantibodies with specificities against four particular 
linear epitopes.   The strongest of these associations is with a 15–mer peptide sequence (GRP78 aa. 
246-260) that we have denoted as anti-GRP78 Peptide 25 (Figure 5).   The use of specific peptide

epitope targets in subsequent ELISA and other autoantibody detection assays will improve 
reproducibility, diagnostic sensitivities and specificities, potentiate development of assays using 
panels of atherogenic autoantigens, and eliminate confounding introduced by vagaries of tertiary 
structure (e.g., folding) that we have noted among different batches of intact, whole recombinant 
GRP78.    
 
How Does Autoimmunity Arise?   COPD and COPD probably do not start as autoimmune 
diseases.  Autoimmunity usually develops subsequent to other injurious processes, such as 
infections, cancer, etc., by epitope spread or mimicry, or other unknown mechanisms.14-19 Most 
“secondary” autoimmunities are probably clinically benign.  In some cases, however, these “new” 
immune responses cause striking additional morbidity, e.g., carditis or nephritis following otherwise 
trivial Streptococcal infections, neurologic syndromes associated with cancer, and many others.14-16   
The microbiome within smoke-damaged lungs is highly immunogenic, and the chronic immune 
responses that result are also likely conducive to the development of autoimmunity.20   In addition, 
neoantigens generated by reactive constituents within tobacco smoke can also provoke autoimmune 
responses.21

upper limit of normal for IMT.13  O.D. = optical density of ELISA determinations.  B) Anti-GRP78 Peptide 25 
levels are greater in COPD patients with abnormally increased carotid IMT (n = 26) vs those with normal IMT 
(n = 38) per Mann-Whitney comparisons.  Ascending horizontal lines successively denote 10th, 25th, 50th, 75th, 
and 90th percentiles.  Solid squares denote mean.  These carotid-autoantibody associations were less 
significant among subjects who did not have pulmonary COPD.  
  
The involvement of autoimmune processes in the pathogenesis of smoking-associated lung 
disease could account for well-known, but heretofore enigmatic, observations that pulmonary 
inflammation among these patients often persists, and their respiratory function frequently continues 
to rapidly deteriorate, despite removal of the inciting injury (e.g., tobacco smoking).22  Once 
autoimmunity develops, the process has a tendency to be self-perpetuating, or at least recurrent, 
since the autologous protein(s) [autoantigen] that is the target of this immune responses is continually 
being renewed.   
Furthermore, an autoimmune pathogenesis can also help explain the resistance of these 
disorders to medical therapies, including aerosolized and systemic glucocorticoids.  Many 
autoimmune diseases, and autoantibody-mediated lung diseases in particular, are also highly 
resistant to steroids and nonspecific agents.  Among these examples, granulomatosis with polyangitis 
(“Wegener’s syndrome”), Goodpasture’s syndrome, acute interstitial lung diseases associated with 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD

polymyositis, RA, or other classical autoimmune diseases, and lung transplant rejection due to 
alloantibodies, have very high rates of progression and mortality when treated primarily (or solely) 
with steroids.  In contrast, targeted therapies that reduce autoantibodies or diminish their production 
can benefit patients afflicted with these syndromes.23-34     
The findings described in the preceding section led us to posit: Autoantibodies play a causal 
role in smoking-related COPD, osteoporosis, and atherosclerosis in patients with this lung 
disease.  A corollary of this paradigm is that autoantibody reduction therapy with belimumab may 
delay (or maybe even prevent) progression of these disorders better than current nonspecific 
therapies.   
The foregoing series of studies (and others) provide a rationale to treat at-risk COPD patients with 
biological agents that were developed for therapy of other autoantibody-mediated diseases.33,34 Our 
studies have also identified a mechanistic biomarker (anti-GRP78 IgG autoantibodies) that will be a 
useful surrogate endpoint in early phase clinical trials (as we intend to employ it here).6   
We propose to begin to test our hypothesis in an unprecedented bench-to-bedside pilot trial in 
which we aim to decrease autoantibody concentrations in COPD patients by using belimumab, a 
commercially-available biological agent with activity against BLyS. 
 
1.5 SIGNIFICANCE 
If our central hypothesis is correct, targeted therapy to reduce pathogenic autoantibodies could 
ultimately result in significant benefit for a lung disease, and associated comorbidities, that have been 
inexorable.  
 
2   RESEARCH DESIGN AND METHODS 
 
2.1  CLASSIFICATION AND METHODOLOGICAL DESIGN 
 
This is a randomized, double-blinded placebo-controlled Phase II clinical trial to explore the use of 
belimumab in patients with smoking-associated COPD and autoantibodies. 
 
2.2  STUDY DESIGN  
 
Subjects: Eighteen (18) subjects will be recruited for this project from among ambulatory patients in 
The Kirklin Clinic (TKC) or Lung Health Center (LHC) at the University of Alabama in Birmingham 
(UAB). The LHC is directed by Dr. Dransfield, a Co-PI of this proposal.  Potential participants of both 
genders and all ethnicities will be eligible for this trial.  No special populations will be studied.   
 
Recruitment Methods: The recruitment process will begin via one of two possible pathways:  
 
1) Referral of the prospective participant to the investigators/research coordinator by a clinic 
physician who has knowledge of the proposed research, and obtains patient consent for the research 
team to approach the patient.   
 
2) Alternatively, individuals who have provided signed IRB-approved HIPPA compliant consent for 
participation in clinical trial research registries may be approached by a designated investigator in 
those registries.  The LHC maintains a registry of more than 1000 COPD patients who could be 
screened for potential participation in the trial.

Following procurement of informed consent and completion of baseline screening assessments, 
patients that meet all inclusion/exclusion criteria will be randomly assigned to receive one of the two 
following treatments, starting on Day 1, in a ratio of 2:1.   
 
1.) EXPERIMENTAL BELIMUMAB TREATMENT (n=12).    Subjects randomized to the 
experimental treatment arm will receive i.v. administrations of belimumab (10 mg/kg), consisting of 
three "loading" doses, two weeks apart, followed by five (5) more monthly infusions.  The final 
assessment will be performed at month 7 (see Table 1).     
 
2.) PLACEBO CONTROLS (n=6):  These subjects will be treated with identically appearing 
placebo i.v. on the same schedule as the experimental arm subjects (i.e., three "loading" doses, two 
weeks apart, followed by five more monthly infusions.  The final assessment will be performed at 
month 7 (see Table 1).

2.6 STUDY PROCEDURES  
 
Routine clinical care for patients with pulmonary COPD will be followed as ordered by the 
primary physician.  
 
All subjects will have infusions of study medications (belimumab or placebo) in an expert, dedicated, 
continuously-monitored UAB infusion center at the intervals delineated in Table 1. The treatment 
protocol will last for 180 days (6 months), with a final observation and specimen collection at day 210 
(7 months) (see Table 1).  Patients removed from the study for unacceptable AE will be followed 
until resolution or stabilization of the problem(s).  Telephone interviews to detect potential late 
complications and outcomes will be conducted by study coordinators at other intervals (see Table 2).

Patients will be monitored carefully while participating in this study for occurrences of adverse 
events, laboratory test abnormalities, and changes in vital signs.  Adverse events will be 
evaluated according to criteria outlined in the NCI Common Terminology Criteria for Adverse 
Events (CTCAE), version 4.0.    
 
Belimumab will be administered IV over a minimum of 1 hour.  The infusion rate may be slowed or 
interrupted if the subject develops an infusion reaction. In the event of a serious reaction, study agent 
administration must be discontinued immediately and the appropriate medical therapy administered. 
 
In the post-marketing setting, delayed onset of symptoms of acute hypersensitivity reactions has 
been observed, especially in the first or second infusion. Subjects will remain under clinical 
supervision for 3 hours after completion of the first 2 infusions.  Should symptoms of acute 
hypersensitivity occur, an extended period of monitoring may be appropriate, based on clinical 
judgement. This may include, but is not limited to, monitoring vital signs and observing any untoward 
reactions. Beyond the first 2 infusions, subjects should be monitored during infusion and for an 
appropriate period of time after infusion (this will generally be one hour, again based on investigator 
judgement). 
 
Subjects should be made aware of the potential risk, the signs and symptoms of such reactions, 
and the importance of immediately seeking medical attention. For further information, see the 
belimumab IB.  
 
Venous blood for experimental purposes (e.g., end-point measures), totaling 29 ml, and study-
specific pulmonary function tests (i.e., spirometry and diffusing capacities), will be obtained at 
screening (baseline) and at 1, 3, 5, and 7 months after treatment started (Table 2).  Additional 
venous phlebotomy specimens for safety monitoring tests and assays appropriate for the 
experimental use of belimumab will be obtained at these and other intervals as needed (specified 
below).   
 
The results of the pulmonary function tests, clinical data, and safety studies will be logged in 
case report forms (CRF) as they are generated (in real time).  The experimental laboratory 
(immunological) assays will be performed intermittently among accumulated batched specimens 
and results recorded as they are performed. 
 
 
2.6.1 Screening 
Screening:  Following informed consent, patients will undergo screening assessments to determine 
that all inclusion/exclusion criteria are met prior to randomization or receiving the study drug 
treatments.   
The following screening information will be collected and entered into the study case report forms 
(CRFs) and/or web-based data collection system.

All research specimens and all records associated with the samples will be labeled only with a 
unique code that links to the trial data but contains no personal identifiers. The information linking 
these code numbers to the corresponding subject’s identity will be kept in a secure location in the 
contact PI’s office, and will not be available to staff managing samples at the research laboratory.  
 
Specimen Management and Storage: Specimens in excess of immediate assay requirements 
may be stored indefinitely in a secured freezer under the control of the responsible PI.  The 
coding information linking patient identifiers to the stored samples will be maintained in a locked, 
secure area that will be accessible only to the study investigator. Subjects may request to have 
their samples destroyed at any time. These samples will be destroyed immediately upon receipt 
of the subjects’ written request to do so. 
 
Restrictions to Direct Access of Specimens:  Specimens will be kept in the responsible study 
investigators’ laboratory indefinitely and will be under the control of the PIs.  Investigators or 
other personnel not involved with the management or operations of the study are not permitted 
direct access to the specimens.  
 
 
 
2.7  STUDY ENDPOINTS 
 
2.7.1. The Primary End-Point: 
 
The primary endpoint of this trial is a reduction of circulating levels of anti-GRP78 Peptide 25,  a 
clinically relevant surrogate biomarker of "autoimmunity" in these patients. Plasma concentrations of 
the anti-GRP78 autoantibodies will be measured pre-treatment, and at 1, 3, 5, and 7 months after 
treatment start.  
 
General:  Heparinized blood for end-point measures will be obtained from subjects by venous 
phlebotomy.  Gentle centrifugation will separate cells from plasma, which will then be aliquoted and 
appropriately stored for assays of anti-GRP78 IgG (primary endpoint) and anti-pneumococcal 
antibodies (a secondary endpoint). A separate unanticoagulated tube (red top) will be used to procure 
sera.  Peripheral blood mononuclear cells (PBMNC) will be isolated from the residual heparinized 
specimen by resuspension and density gradient centrifugation.  PBMNC will be used for B-cell studies 
(a secondary endpoint), and residual cells will also be stored frozen as dry pellets and in RNase 
protection media for potential later use (e.g, cloning and sequencing autoreactive B-cell IgG).    
 
Anti-GRP78 IgG levels will be measured in serial specimens by a custom ELISA that has already been 
developed, validated, and employed (see Figs. 4,5).   In brief, biotinylated GRP78 Peptide 25, which 
was synthesized by Thermo Scientific (Waltham, MA) is diluted to 0.5ug/ml in PBS and added to 
streptavidin-coated ELISA plate wells and incubated overnight at 4o C.  After thorough washing and 
blocking, patient plasma specimens (see Section 2.8.2) are added to the wells at 1:100 dilutions and 
incubated for 2 hours at room temperature. Following additional washes, alkaline phosphatase-
conjugated goat anti-human antibody (1:5000 dilution) is added, incubated, and color developed with a 
pNPP substrate system (KPL, Gaithers-burg, MD). Optical densities (OD) are determined at 405 nm.  
 
 ELISAs against GRP78 and epitopes within this molecule are accurate and reproducible.  We used 
identical aliquots of several specimens in assays performed by multiple different lab operators, 
separated temporally by up to 1 year.  Despite these variables, the ELISA yielded concordant values 
with r > 0.96.  Similarly, serial anti-GRP78 IgG measures in specimens collected after two-year intervals 
from a group of COPD patients yielded r > 0.82.  Most of the differences in OD values in the serial 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD 
_________________________________________________________________________________________________________ 
22 
 
measures seemed to be inversely concordant with interval changes of patient's clinical status (e.g., 
anti-GRP78 OD tended to increase as their lung disease severity got worse).   
 
 
2.7.2. Secondary End-Points  
 
Specific Aim 2 Endpoints: The secondary endpoints of this trial are: 1.) treatment effects on 
concentrations of pneumococcal polysaccharide-binding antibodies by ELISA33,36 2.) treatment effects 
on absolute numbers and phenotypes of circulating B-cells by flow cytometry,8 and 3.)  Adverse event 
comparisons. 
 
Secondary endpoint #1. (anti-pneumococcal antibodies) and #2. (B-cells) will be assessed among 
blood specimens obtained prior to treatment, and at 1, 3, 5, and 7 months after treatment starts.   
Secondary endpoint #3 (AE) will be assessed at each clinic visit, telephone encounter and in 
communications initiated by subjects or study personnel at any other interval.   
 
a.) Pneumococcal polysaccharide-binding antibody concentrations in plasma will be measured 
pre-treatment, and compared to results at the aforementioned intervals after treatment started.  The 
ELISA methodology is straightforward, highly standardized, and fully detailed previously.36  
 
b.) B-cell numbers and phenotypes will be assessed at the same time-points. Method-ologies are 
also well established and have been previously detailed.8 In brief, B-cells will be stained with panels of 
fluorochrome-conjugated monoclonal antibodies and characterized by flow cytometry.  B-lymphocytes 
will be identified as CD3-/CD14-/CD16-/CD19+ cells, and further stratified for comparisons as transitional 
(IgD+/CD38++),  IgM+ IgA- IgG- switched memory (IgD+/CD27+), IgG+ switched memory (IgD-/CD27+/-), 
and plasmablasts (CD19lo/+, CD20-, CD38++, IgD-, CD27++).8   
 
c.) Adverse Events: The NCI Common Toxicity Criteria Scale will be used to define grades (severity) 
of adverse events and toxicities.  An adverse event is defined as any untoward medical occurrence in a 
subject, regardless of its relationship to these treatments. Toxicity is an adverse event with a direct 
relationship to the study drug.  All toxicities are adverse events, but not all adverse events are toxicities.  
Case report forms (CRF) will require responses to all adverse events (and negatives), with a particular 
focus on allergic reactions, infections (including location and organism), and neuropsychiatric 
symptoms.  Recording adverse events in pre-specified checklists (and free text entries) in all subjects 
will guard against unintended bias.   
  
2.7.3 Other Measures that are not a Formal End-Point:  Carotid artery ultrasounds (US) will 
be obtained in participants at baseline evaluations and at the conclusion of formal 
observations (day 210), in order to determine carotid intimal medial thicknesses (IMT).  
We do not believe there is a high likelihood there will be a significant treatment effect, 
given the small number of participants and short duration of therapy in this exploratory 
trial.  Nonetheless, these tests will establish the feasibility of using these assays in 
subsequent larger and longer trials to examine effects of autoantibody reduction in COPD 
patients.  
 
 
2.8 DATA AND POWER ANALYSES 
 
2.8.1 Primary Endpoint Data Analyses:  
 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD 
_________________________________________________________________________________________________________

Baseline demographic and clinical data of participants will be summarized using means (with standard 
deviations) and medians (with inter-quartile ranges) for continuous variables, and counts and 
percentages for discrete variables, stratified by treatment group.  Differences among groups (to 
examine the randomization effectiveness), will be assessed by t-tests, or by Fisher’s exact test for 
discrete data, recognizing the limited power of our small trial. 
  
Repeated measures linear mixed models will be used to evaluate differences of immunological 
parameters (continuous variables) that comprise the primary, and most second endpoints.  These 
models will track the changes over time as well as allow for missing observations, which should be 
minimal.  In general, analyses will follow intention to treat principles, with the last observed outcome 
over all time points being used as the primary measure for a given variable.   
 
The sample size of 18 subjects for this clinical trial is based on exposing a minimum number of patients 
to potential risks of the experimental therapy, while having the potential to obtain useful information.  
Given that this trial is unprecedented, it is impossible to use preliminary data to definitively derive power 
analyses.  Indeed, an important purpose of this study is to generate credible and relevant preliminary 
data in this population to power subsequent larger trials.  Trials to detect clinical efficacy (e.g., change 
in pulmonary function tests, reductions in acute exacerbations, etc.) will almost certainly require 
treatment of many subjects over prolonged periods.  
 
With these limitations in mind, we can assume belimumab effects in COPD patients are similar to 
those among patients with SLE.  Thus, we can expect to see reductions of anti-GRP78 autoantibody 
concentrations by ~30%, in addition to ~50% reductions of several circulating B-cell subpopulations, 
by or after approximately 6 months of therapy.   With respect to the primary endpoint (reduction of anti-
GRP78 IgG): If the true difference in the experimental and control means is 30%, with standard 
deviations that are two–thirds of this (20%), we will need to study 12 experimental subjects and 6 
control subjects to reject the null hypothesis that the population means of the experimental and control 
groups are equal, with probability (power) 0.8.   The Type I error probability associated with this test of 
the null hypothesis is 0.05.   
 
The 2:1 experimental arm: control enrollment will increase the amount of data regarding effects and 
safety of this drug in COPD patients, and only increases the necessary subject number to reach 80% 
power by two, compared to 1:1 enrollment. 
 
2.8.2 Secondary Endpoint Data Analyses:  Analyses will again follow intention to treat principles, 
with the last observed outcome over all time points being used as the primary measure for a given 
variable.  Multiple imputation will be used based on subject characteristics to assess the obvious 
issues with last observations carried forward in these analyses.  Trajectories over time, for a given 
patient and outcome measure, will be displayed via line graphs, and assessments conducted using 
linear mixed models on the repeated time points.  Comparisons between the treatment arms of the 
polysaccharide binding assay concentrations and B-cell parameters at various time points will be 
made using repeated measures techniques. Transformations of these tests may be needed, such as 
velocities, if many individuals are unable to complete the entire treatment protocol.  The proportion of 
subjects with adverse events and the count of adverse events per subject will be compared by 
treatment using Fisher’s exact test and the exact Poisson tests, respectively. 
 
 
2.8.3 Interim Analysis: Since the primary endpoint of this trial is a laboratory test and surrogate 
biomarker, rather than a clinical outcome parameter, and the subject number is small, no interim 
analysis will be conducted for efficacy.

2.9 ANTICIPATED RESULTS, ALTERNATIVES, AND PITFALLS 
 
2.9.1 Specific Aim 1 (Primary Endpoint).   
 
Specific Aim 1 Anticipated Results:  Based on the known action of belimumab in other disease 
populations,33,34 we anticipate anti-GRP78 reductions will be greatest in experimental arm subjects.   
 
Specific Aim 1 Alternative Experimental Therapies: In comparisons to other agents used for 
treatment of autoantibody diseases, belimumab is almost certainly the safest, particularly with 
respect to risks for later infections.23,33,34,37   We conservatively assume all subjects will have lower 
airway microbial colonization.20 The potential that autoantibody reduction treatment could promote 
infections is a singular consideration in this subject population.  Nonetheless, at least among SLE 
patients, belimumab reduces pathogenic autoantibodies, but leaves protective host defense 
antibody titers largely preserved.33 Confirming this happens too in COPD patients is an important 
secondary endpoint.  Experts with use of belimumab in SLE do not rigorously evaluate their patients 
for infections prior to initiating therapy (e.g., pre-treatment bronchoscopy is not indicated), nor 
reduce doses with infections other than those that are serious (W. Chatham, personal 
communication). 
 
In contrast, other potential agents, including cyclophosphamide, alemtuzumab and bortezomib, 
experimental anti-CD19 monoclonal antibodies, other anti-T-cell agents, and rituximab are more 
toxic and far more likely to promote infections (including opportunistic infections).  Moreover, with 
the exception of rituximab, the efficacy of these other, riskier agents for treatment of autoantibody-
mediated autoimmune disorders has not been established. 
    
Specific Aim 1 Potential Pitfalls:  Even if the experimental regimen decreases autoantibodies and 
is safe, it is unlikely to reverse the lung destruction, and vascular and other tissue injuries that 
already afflicted these patients prior to the start of therapy.  Nonetheless, slowing the rate of 
disease progression, particularly for otherwise untreatable morbid or lethal disorders, is still a 
worthwhile goal.    
 
Our subject numbers are small, and this will limit our power to detect small intergroup differences, 
especially if there are biological differences of drug actions within our demographically and 
ethnically heterogeneous study population.  This problem(s) will be confounded if there are several 
subject drop-outs due to the development of acute exacerbations, or if they lose interest and quit 
participating.   
 
We have attempted to minimize the potential number of acute exacerbation drop-outs by excluding 
those patients with the single greatest risk for these complications (i.e., those who have a history of 
same).  And the UAB LHC has a very good record for retaining trial subjects (approaching 100% in 
several studies).  Furthermore, our data analysis methods should still enable us to make meaningful 
intergroup comparisons if there are subject drop-outs (see Data Analyses).  
 
The alternative would be to propose a much bigger and more expensive initial trial, in the face of 
having absolutely no prior experience in COPD patients with this particular agent, or even this 
general approach.  However, this would expose many more subjects to potential risks of the 
experimental intervention, prior to having any indication of effectiveness or safety.  
 
The effectiveness of belimumab in autoimmune COPD patients is currently unknown, and it is 
conceivable that the autoimmune responses in this lung disease population are actually more 
fulminant, or otherwise more refractory, than those of SLE patients.  Of course, a rationale for the 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD 
_________________________________________________________________________________________________________ 
25 
 
proposed study is to begin to explore this possibility.  If, for whatever reason(s) COPD autoimmunity 
is resistant or partially resistant, it will further hinder our ability to find a treatment effect. Based on 
results of clinical trial results in other disease populations, and general biological 
considerations,23,33,34,37 we are confident that belimumab will, in fact, detectibly reduce anti-GRP78 
IgG in the treatment arm, and will likely alter circulating B-cell populations as well, even given the 
inherent limitations of this trial.    
 
There are almost certainly other processes, and other autoantibodies, not-yet-discovered, that may 
also be involved in the development and/or progression of COPD and its comorbidities.  The 
concurrent presence of diverse autoantibodies is a feature of autoimmune syndromes.38-41 As 
one of many examples, SLE and scleroderma are notable for the presence of particular 
autoantibodies, but >100 other autoantibodies are also present in these patients, and many of these 
immunoglobulins are highly related to particular disease phenotypes.40,41 Even if other autoantibody 
specificities are also important, as we suspect, our data show that GRP78 autoreactivity per se  is 
highly associated with the presence and severity of COPD and many of its associated comorbidities 
(Figs.2-5).  It is implausible to postulate that belimumab will have differential effects on 
concentrations of anti-GRP78 IgG compared to other (if undiscovered) pathogenic autoantibodies.  
Hence, even if other important and yet-to-be-recognized autoantibodies are present, values of our 
already developed and reproducible anti-GRP78 ELISA should change in parallel, and thus these 
results will be a useful generalizable measure of the autoantibody changes that occurred during this 
trial.  
 
Admittedly this trial is a high risk endeavor, which is a characteristic of pioneering studies.  
Nonetheless, we believe that voluminous data support the central premise here.  Furthermore, the 
enormous individual and public heath burdens that are attributable to these diseases, and their 
refractoriness to currently available medications, mean that the potential rewards of this novel 
therapeutic approach are also very high.   
 
 
2.9.2 Specific Aim 2 (Secondary Endpoints) Anticipated Results and Pitfalls 
 
Specific Aim 2 Anticipated Results:   
a.) Pneumococcal polysaccharide-binding antibody concentrations:  Based on results of 
analogous studies that examined belimumab effects in other populations (primarily SLE patients), 
we anticipate the experimental treatment will have only modest effects on concentrations of these 
important host defense immunoglobulins.  Proving these antibodies are also minimally, if at all, 
affected in COPD patients (a novel trial population) is an important element of this pilot study.  Dr. 
Duncan is an expert with these types of assays and no technical problems are anticipated. 
 
b.) B-cell Effects:  Again, based on analogous literature in SLE populations, we anticipate a 
gradual shift in circulating B-cell phenotypes among the experimental treatment subjects, 
particularly those at the higher doses.  In particular, we anticipate increases in proportions of less 
differentiated lymphocytes and corresponding decrements of more differentiated phenotypes.  Dr. 
Duncan is also experienced with these assays and no technical problems are anticipated.       
 
c.) Adverse Events: Based on multiple studies involving thousands of patients treated with 
analogous regimens, we anticipate high-grade adverse events will not be significantly more 
frequent among experimental arm subjects, and the experimental regimen will have an acceptable 
risk:benefit ratio.33,34,37  Examining the safety of belimumab in this potentially high-risk population is 
a critical aspect of our small and conservatively biased pilot trial.  It is conceivable this study will 
show that even carefully selected and closely observed COPD patients cannot tolerate any immune

suppression, even relatively benign belimumab. Even if so, these negative results (albeit 
disappointing) will be highly valuable, given the increasing interest (and seemingly 
increasing amount of supportive data and rationale) for therapeutic targeting of the 
autoimmune responses in these diseases.9,10 
 
 
2.10 STUDY TIMELINES AND MILESTONES 
 
Timelines and Milestones:  Infrastructure and regulatory requirements should be completed by <6 
months after funding is awarded (Table 3).  The personnel of this project have considerable clinical 
trial experience.  Our potential subject population is so many times greater than the necessary study 
numbers that we anticipate being able to meet our target goal enrollment before the end of the project 
duration.

3  HUMAN SUBJECTS 
 
3.1 SUBJECT POPULATION 
 
Human Subject Characteristics: 
The study population will be eighteen (18) adult patients with COPD and autoantibodies against 
GRP78.  The subjects will be recruited from the clinics or registries of the Lung Health Center 
(LHC) at the University of Alabama at Birmingham (UAB). The trial subjects must provide written 
informed consent prior to participation.  Surrogate consent will not be allowed.  No special 
vulnerable populations will be studied. 
 
The demographics of the study population will reflect the characteristics of patients who suffer 
from COPDand are evaluated at at the University of Alabama at Birmingham (UAB) clinics and 
LHC..  These will be older patients (COPD is predominantly a disease of mature and elderly 
individuals).  The ethnicities of the subjects will similarly reflect the demographics of our clinic 
populations that are afflicted with this disease. We anticipate that our recruited population will be 
50% female, 75% Caucasian and 25% African American) 
 
Recruitment goals (~9 subjects/year) are easily feasible, based on the large number of potential 
participants available here at UAB..  This pulmonary clinics at this academic medical center

routinely sees hundreds of new patients annually, and the majority of these have COPD.  The 
UAB LHC has a long history of success in the recruitment and retention of participants in various 
studies, and has routinely been among the top recruitment sites in several large, NIH funded, 
multicenter clinical trials.  A full time recruiter is employed at the LHC, who relies on in-clinic 
contact with potential participants, as well as print, television, and media advertising, as needed.  
There are currently over 1000 patients with COPD in the LHC databases and several hundred in 
the active research registries of the Center.     
 
3.1.1 Inclusion of Women and Minorities 
Women who meet the inclusion criteria, and have none of the exclusion criteria, will be enrolled 
without restriction as dictated by the study protocols.  Because of the use of a study medication, 
woman of child bearing potential must meet specialized inclusion/exclusion criteria to minimize this 
risk. We will make efforts to enroll participants in this research in a distribution that mirrors the 
clinic population at our center  (50% female, 75% Caucasian and 25% African American)..   
 
3.1.2 Inclusion of Children 
Children under 18 years of age will not be enrolled because they do not develop this disease.  
 
3.2  INCLUSION AND EXCLUSION CRITERIA 
The inclusion criteria have been selected to study a patient population with COPD and 
autoimmunity.   The exclusion criteria are selected to exclude patients with increased risk for the 
experimental intervention.   
 
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.)  Clinical diagnosis of at least moderate COPD as defined by the Global Initiative for 
Obstructive Lung Disease (GOLD) criteria: 
 
 
a. Post bronchodilator FEV1/FVC < 70%, 
 
 
b. Post bronchodilator FEV1 between 25% and 80% predicted, with or without chronic 
symptoms (i.e., cough, sputum production). 
COPD 
3.)  Ability and willingness to give informed consent.  
 
4.) Levels of plasma autoantibodies that have specifities against a 15–mer peptide sequence 
within the GRP78 molecule (aa. 246-260) that are in the upper three quartiles of values present 
in COPD patients.   We have discovered that circulating levels of IgG autoantibodies with avidity 
against this peptide (GRP78 Peptide 25) are associated with the magnitude of carotid artery 
intimal medial thickness (IMT) among COPD patients (Figure 5).  Limiting enrollments to subjects 
with readily detectible autoantibodies (e.g., those with levels in the 25th percentile or above) will 
easily enable us to ascertain if the experimental treatment (belimumab) results in a significant 
reduction of these autoantibodies.    
 
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 screening. 
 
13.) Use of parenteral (IV or IM) antibiotics (antibacterials, antivirals, anti-fungals, or 
anti-parasitic agents) within 60 days of screening. 
 
14.) Current drug or alcohol abuse or dependence, or a history of drug or alcohol abuse or 
dependence within 365 days prior to screening. 
 
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.

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

in the product label 
o 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

4  RECRUITMENT AND INFORMED CONSENT PROCEDURES 
 
4.1  RECRUITMENT METHODS 
 
Subjects will be recruited from the outpatient population followed at The Kirklin Clinic and UAB 
LHC.  The primary care physician/clinical care team, who may be study investigators or 
colleagues of the study investigators, will first identify potential research subjects.  The clinician 
investigators will discuss the research project with the potential subjects.  
 
 
4.2  INFORMED CONSENT PROCEDURES 
 
The consent process will begin via one of two possible pathways:  
  
 
1) Referral of the prospective participant to the investigators/research coordinator by a physician 
who has knowledge of the proposed research, and obtains patient consent for the research 
team to approach the patient/surrogate. 
 
2) Individuals who have provided signed IRB-approved HIPPA compliant consent for 
participation in clinical trial research registries.   
 
Subjects must provide informed consent prior to performing any of the study procedures.  The 
information about this study will be given to subjects in language understandable to subjects.  
Only physician investigators will present the study to the potential subjects. The physician 
investigator will verbally present a general outline of the research plan, including inclusion and 
exclusion criteria, to the prospective participant. The consent form, outlining the design of the 
study, will include the risks and benefits of participating, and will be reviewed and the investigator 
will answer any questions. Prospective participants may take as much time as required to make 
an informed decision. Written informed consent will be obtained from each participant prior to 
performing any research study procedures. 
 
In addition, older potential study participants whose competency to consent is in question will be 
tested for sufficient comprehension and recall of the information presented. Prospective subjects 
who do not remember the important facts about participation in the research study after repeated 
testing will not be included in the study. The investigators will also assess whether a participant 
understands experimental procedures over time, including assessment throughout the full duration 
of participation in the study.  
 
 
5 POTENTIAL RISKS AND BENEFITS 
 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD 
_________________________________________________________________________________________________________ 
31 
 
5.1.1 General Risks of Study Protocol and Procedures 
The potential subject risks specifically related to the study protocol procedures could include 
loss of confidentiality or actual physical harm due to experimental intervention as outlined in 
5.1.2. 
 
5.1.2 Potential Risks of Experimental Intervention 
 
The potential subject risks specifically related to the study protocol procedures could include: 
 
Venipuncture:  
Common Risks: temporary, minor discomfort, bruising. 
 
Other Risks: infection, bleeding and phlebitis. 
 
Belimumab: Common risks are temporary and self-limited or treatable with over the counter 
(OTC) medication (e.g., Benadryl, Tylenol).  The common adverse effects reported with 
belimumab include nausea, diarrhea, and fever, as well as hypersensitivity and infusion-site 
reactions.  However, there were few differences between treatment and placebo patients in the 
monitored clinical trials.  Infusion reactions were reported in 17% (251/1458) and 15% (99/675) 
of patients receiving belimumab and placebo, respectively. Serious infusion reactions 
(excluding hypersensitivity reactions) were reported in 0.5% of belimumab patients and 0.4% of 
placebo patients. 
 
Serious infection rates were comparable among drug and placebo cohorts (6.0% and 5.2%, 
respectively). Progressive multifocal leukoencephalopathy (PML) resulting in neurological 
deficits, including fatal cases, has been reported in SLE patients receiving immunosuppressant 
pharmacotherapy, including belimumab. 
 
There were 14 deaths during the controlled period of three clinical trials: 3/675 in placebo, 5/673 
in belimumab 1 mg/kg; 0/111 in belimumab 4 mg/kg, and 6/674 in belimumab 10 mg/kg.  Causes 
of death included infection, cardiovascular disease, and suicide.   
 
There are no known drug interactions, and the only absolute contraindication is a history of 
anaphylaxis to belimumab.   
 
 
 
5.2 ALTERNATIVE TREATMENTS 
 
The alternative treatments for the subjects participating in this investigation are to continue their 
usual medical care under the direction of their attending physician. 
 
 
5.3 POTENTIAL BENEFITS 
 
Participation in the proposed research may or may not provide a direct benefit to the subjects.  
Potential benefits from the participation in this protocol include enhanced survival, improved 
respiratory symptoms, and decreased exacerbation frequency and/or severity. Identification of the 
mechanism(s) mediating these outcomes will facilitate risk-stratification for these adverse outcomes, 
and development of targeted treatment strategies for the future.   
 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD

Based on the preceding assessment of risks and potential benefits, the risks to subjects are 
reasonable in relation to anticipated benefits.  The research presents a balance of risks and 
expected direct benefits similar to that available in the clinical setting.  
 
Importance of the Knowledge to be Gained:  The preliminary data in this application outline a 
hypothesis for the development and/or progression of COPD and associated comorbidities.  The 
protocol specifically seeks to address that hypothesis.  If the study intervention is found to be both 
safe and effective in the study population, the treatment of these patients would be altered 
significantly, and ultimately could lead to a change in the disease natural history.  Completion of 
these protocols will begin to address important questions related to COPD and associated diseases. 
 
 
5.4 RISK MANAGEMENT PROCEDURES 
 
5.4.1 Protection Against Loss of Confidentiality  
 
All research interventions/activities will be conducted in private patient care areas. The collection 
of sensitive information about subjects is limited to the amount necessary to achieve the aims of 
the research, so that no unneeded sensitive information is being collected. 
 
To avoid any violation of subject confidentiality, all data will be stored in a password-protected 
database as well as Case Report Forms (CRFs), identified only by study ID number.   A 
confidential database linking patient identifying information with study ID number will be 
maintained by the PIs.   
 
All demographic and clinical information about the subject will be stored in a secured study 
database under the supervision of the PIs for this protocol. All staff will sign confidentiality 
statements.  
 
Specimens will be stripped of subject identifiers and stored according to a similar coding protocol 
as described above. These specimens will be stored safely in the custody of the PIs responsible 
for the individual assays. These Investigators will limit future access to any remaining sample to 
only those investigators with prior IRB approval for their studies. 
 
The PIs will retain the data for the entire period of this study. The investigators may continue to 
use and disclose subjects de-identified information for the purpose of this study for a minimum of 
seven years after final reporting or publication of the study. If the subject and/or legal 
representative decide to withdraw or be withdrawn from study participation, they may request 
that the study data and samples be destroyed. 
 
All staff involved in this study are properly credentialed and instructed in the areas of testing, 
confidentiality, and safety.  All principal and co-investigators, coordinators, and other Key 
Personnel are required to participate in courses and be certified as mandated by local IRBs 
regarding human subjects’ protections.   
 
 
5.4.2 Protection Against Risks of Experimental Procedures  
 
Despite the documented safety profile of the study medication in other human disorders of 
abnormal immune regulation, the study has been designed with a focus on protecting patients 
against risk including: 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD 
_________________________________________________________________________________________________________ 
33 
 
 
Selection of a target patient population with a high risk of morbidity and mortality due to 
the absence of definitive medical treatment for the disorder 
 
Involvement by trained staff/investigators with experience in the administration of 
belimumab 
 
Prior human experience with the study medication in other autoimmune disorders, 
including (SLE). 
 
Selection of a study population that is not taking other immunosuppressive agents will 
lessen risks of infections.   
 
Continuous monitoring by an independent Data Safety Monitoring Board (DSMB). 
 
Use of low rates of infusions (>1 hour), with continuous monitoring and observations, 
during study drug administrations.  Subjects will be visited and observed by study 
personnel during each of their treatments.  Subjects will also be contacted by phone on 
the day following their study drug administrations.  Assessments for adverse events will 
occur at each of those contacts.  
 
Infusion reactions occurred more frequently on the first two infusion days and tended to 
decrease with subsequent infusions. Delay in the onset of acute hypersensitivity 
reactions has been observed and recurrence of clinically significant reactions after initial 
resolution of symptoms following appropriate treatment, have been observed.  Therefore, 
patients will be monitored during and for an appropriate period of time after administration 
of belimumab.  Subjects will remain under clinical supervision for 3 hours after completion 
of the first 2 infusions.  Should symptoms of acute hypersensitivity occur, an extended 
period of monitoring may be appropriate, based on clinical judgement. This may include, 
but is not limited to, monitoring vital signs and observing any untoward reactions. Beyond 
the first 2 infusions, subjects will be monitored during and for an appropriate period of 
time after infusion according to the study sites’ guidelines or standard operating 
procedure for IV infusions. Subjects will be made aware of the potential risk, the signs 
and symptoms of such reactions, and the importance of immediately seeking medical 
attention. Delayed-type, non-acute hypersensitivity reactions have also been observed 
and included symptoms such as rash, nausea, fatigue, myalgia, headache, and facial 
edema. 
 
Subjects will be made aware of the potential risk, the signs and symptoms of allergic 
reactions, and the importance of immediately seeking medical attention.  In addition, 
other physicians who have responsible for various aspects of these subjects medical care 
will have continuous access to study investigators and will be encouraged to immediately 
report suspected adverse events.  Subjects and family members will similarly be 
encouraged to contact investigators for suspected adverse events. Subjects will be given 
a wallet-size card explaining that they are in a research study and that they are assigned 
to receive either belimumab or a matched placebo.  The card will include telephone 
numbers of the responsible investigator.  Subjects will be instructed to carry the card at 
all times.   
 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD

Some autoimmune diseases have an increased risk of suicidal behavior and/or 
ideation.  For this reason in studies of patients with autoimmune disease, patients will be 
clinically assessed for suicidal ideation and/or behavior at each visit by experienced 
medical personnel.   It is not known if the increased risk of suicidality with some 
autoimmune diseases is also present in COPD patients.    
 
PML will be considered in any subject presenting with new-onset or deteriorating 
neurological signs and symptoms. The subject will be referred to a neurologist or other 
appropriate specialist for evaluation. If PML is confirmed, the study agent will be 
discontinued, and the event will be immediately reported to GSK.  
 
Medical treatment for conditions that arise as a result of study participation will not be 
treated by study personnel. The subject will be informed of the problems identified, and this 
information will be transmitted to the responsible attending physician or physician 
designated for the subject. In the event of physical injury resulting from the research 
procedures, medical treatment will be available but not offered free of charge. In addition, 
financial compensation is not available for wages lost because of injury related to the 
research protocol. This will be emphasized at the time of consent. 
 
 
5.5 DATA SAFETY MONITORING PLAN 
      
5.5.1 Data Safety Monitoring Board 
A Data and Safety Monitoring Board (DSMB), independent of the study investigators, will monitor 
the clinical trial outlined in this proposal for the duration of this proposal.  The DSMB will be 
selected by study investigators, in concert and with approval of the sponsor (GSK), from among 
experts in the field.  The Food and Drug Administration has already provided an exemption from 
IND requirements for this protocol.   
 
The DSMB will be expected to meet as needed, but not less than every six months, to review the 
progression of the study including patient enrollment, protocol compliance, and adverse event 
reports. The DSMB will conduct interim monitoring of accumulating data from research activities 
to assure the continue safety of human subjects, relevance and appropriateness of the study, 
and the integrity of research data.  An emergency meeting of the DSMB may be called at any 
time by the DSMB Chair should participant safety questions or other unanticipated problems 
arise. 
 
The UAB study team will assume the following general responsibilities: 
 
• 
Maintain copies of FWA and Institutional Review Board (IRB) approvals. 
• 
Maintain updated roster of participants.  
• 
Verify eligibility. 
• 
Verify response. 
• 
Collect data on protocol specific CRFs. 
• 
Prepare all submitted data for review by the sponsor and DSMB. 
• 
Maintain documentation of Serious Adverse Event reports and submit these to the 
sponsor and DSMB for timely review.   
• 
Post on ClinicalTrials.gov 
 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD 
_________________________________________________________________________________________________________

The study PIs will establish a data collection protocol and mechanism.  Data will be collected on 
paper Case Report forms.  Numerous data quality checks, such as duplicate entry checks, 
double-entry verification, and real-time data checking (e.g., ID verification, range checks) will be 
implemented to ensure that the data are accurate, complete and secure.  Data entry personnel 
will be trained and certified in the correct use of the system.   
 
 
5.6. ADVERSE EVENTS:  
 
5.6.1. Definition of an Adverse Event: 
 
An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation 
subject, temporally associated with the use of a medicinal product, whether or not considered 
related to the medicinal product. 
 
Note: An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the 
use of a medicinal product.  For marketed medicinal products, this also includes failure to 
produce expected benefits (i.e., lack of efficacy), abuse or misuse. 
 
Events meeting the definition of an AE include: 
 
• 
Exacerbation of a chronic or intermittent pre-existing condition including either an increase in 
frequency and/or intensity of the condition 
• 
New conditions detected or diagnosed after study treatment administration even though it 
may have been present prior to the start of the study 
• 
Signs, symptoms, or the clinical sequelae of a suspected interaction 
• 
Signs, symptoms, or the clinical sequelae of a suspected overdose of either study treatment 
or a concomitant medication (overdose per se will not be reported as an AE/SAE) unless this 
is an intentional overdose taken with possible suicidal/self-harming intent.  This should be 
reported regardless of sequelae 
 “Lack of efficacy” or “failure of expected pharmacological action” per se will not be reported as 
an AE or SAE. However, the signs and symptoms and/or clinical sequelae resulting from lack of 
efficacy will be reported if they fulfill the definition of an AE or SAE  
 
Events that do not meet the definition of an AE include: 
• 
Medical or surgical procedure (e.g., endoscopy, appendectomy); the condition that leads to 
the procedure is an AE 
• 
Situations where an untoward medical occurrence did not occur (social and/or convenience 
admission to a hospital) 
• 
Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or 
detected at the start of the study that do not worsen 
• 
The disease/disorder being studied, or expected progression, signs, or symptoms of the 
disease/disorder being studied, unless more severe than expected for the subject’s condition 
 
5.6.2 Definition of a Serious Adverse Event 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD 
_________________________________________________________________________________________________________ 
36 
 
A serious adverse event is any untoward medical occurrence that, at any dose: 
 
a. 
Results in death 
b. 
Is life-threatening 
NOTE:  The term 'life-threatening' in the definition of 'serious' refers to an event in which the 
subject was at risk of death at the time of the event.  It does not refer to an event, which 
hypothetically might have caused death, if it were more severe. 
c. 
Requires hospitalization or prolongation of existing hospitalization 
NOTE:  In general, hospitalization signifies that the subject has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for observation and/or 
treatment that would not have been appropriate in the physician’s office or outpatient setting.  
Complications that occur during hospitalization are AEs.  If a complication prolongs 
hospitalization or fulfills any other serious criteria, the event is serious.  When in doubt as to 
whether “hospitalization” occurred or was necessary, the AE should be considered serious. 
Hospitalization for elective treatment of a pre-existing condition that did not worsen from 
baseline is not considered an AE 
d. 
Results in disability/incapacity, or 
NOTE:  The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions.  This definition is not intended to include experiences of relatively 
minor medical significance such as uncomplicated headache, nausea, vomiting, diarrhea, 
influenza, and accidental trauma (e.g. sprained ankle) which may interfere or prevent 
everyday life functions but do not constitute a substantial disruption 
e. 
Is a congenital anomaly/birth defect 
f. 
Medical or scientific judgement should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize the 
subject or may require medical or surgical intervention to prevent one of the other outcomes 
listed in the above definition.  These should also be considered serious.  Examples of such 
events are invasive or malignant cancers, intensive treatment in an emergency room or at 
home for allergic bronchospasm, blood dyscrasias or convulsions that do not result in 
hospitalisation, or development of drug dependency or drug abuse 
g. 
All events of possible drug-induced liver injury (see Section 5.6.5) with hyperbilirubinaemia 
defined as ALT  3xULN and bilirubin  2xULN (>35% direct) (or ALT  3xULN and 
INR>1.5, termed ‘Hy’s Law’ events (the INR threshold value stated will not apply to patients 
receiving anticoagulants) 
Laboratory and Other Safety Assessment Abnormalities Reported as AEs and SAEs 
Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or other safety 
assessments (e.g., ECGs, radiological scans, vital signs measurements), including those that 
worsen from baseline, and felt to be clinically significant in the medical and scientific judgement 
of the investigator are to be recorded as AEs or SAEs. However, any clinically significant safety 
assessments that are associated with the underlying disease, unless judged by the investigator 
to be more severe than expected for the subject’s condition, are not to be reported as AEs or 
SAEs. 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD 
_________________________________________________________________________________________________________ 
37 
 
Pregnancy 
Any pregnancy that occurs during study participation must be reported to GSK.  To ensure 
subject safety, each pregnancy must be reported within 2 weeks of learning of its occurrence.  
The pregnancy must be followed up to determine outcome (including premature termination) and 
status of mother and child.  Pregnancy complications and elective terminations for medical 
reasons must be reported as an AE or SAE.  Spontaneous abortions must be reported as an 
SAE. 
 
Any SAE occurring in association with a pregnancy, brought to the investigator’s attention after 
the subject has completed the study and considered by the investigator as possibly related to the 
study treatment, must be reported to GSK within 24 hours of learning of its occurrence. 
 
The National Cancer Institute Common Toxicity Criteria Scale will be used to define grades 
(severity) of adverse events and toxicities.  An adverse event is any untoward medical 
occurrence in a participant who received study drug, regardless of its relationship to the study 
drug.  Toxicity is an adverse event with a direct relationship to the study drug.  All toxicities are 
adverse events, but not all adverse events are toxicities.  This is a determination made by the 
study investigator.  The study investigators will classify adverse events as “definitely or most 
likely,” “possibly,” or “very unlikely” due to the study drug.  Toxicity will be defined as an adverse 
event that is definitely, most likely, or possibly caused by the study drug. 
 
The severity of adverse changes in physical signs or symptoms will be classified as follows: 
 
• 
Grade 1 (Mild): asymptomatic or mild symptoms; clinical or diagnostic observation only; 
intervention not indicated. 
 
• 
Grade 2 (Moderate): minimal, local or noninvasive intervention indicated; limiting age-
appreciate instrumental ADL (Activities of Daily Living). 
 
• 
Grade 3 (Severe): medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; limiting self care 
ADL. 
 
• 
Grade 4 (Life-threatening): consequences; urgent intervention indicated. 
 
• 
Grade 5 (Death): event is a direct cause of death. 
 
Assuring patient safety is an essential component of this protocol.  The contact PI has primary 
responsibility for the oversight of the data and safety monitoring.  The study investigators will 
evaluate all adverse events.  All subjects who have adverse events, whether considered 
associated with the use of the study medication or not, must be monitored to determine the 
outcome.   
 
All untoward medical occurrences observed in subjects will be recorded on the participants’ 
adverse event CRF by the study coordinator under the supervision of a PI, with a particular focus 
on infections (including location and organism), metabolic or hemodynamic perturbations (e.g., 
hyperglycemia, hypotension, etc.), liver function test abnormalities, and other, less frequent 
complications (e.g., neurologic and psychiatric symptoms), as well as having provision for free 
text entries.  Recording all adverse events in pre-specified checklists (and free text entries), will 
guard against unintended bias.  The CRFs will then be reviewed for completeness and internal

consistency.  
 
The clinical course of the adverse event will be followed up according to accepted standards of 
medical practice, even after the end of the period of observation, until a satisfactory explanation 
is found or the PI considers it medically justifiable to terminate follow-up. 
 
The PIs will work with the coordinator(s) to prepare a detailed written summary of serious, 
unexpected, and treatment related adverse events, and will compare, and contrast the event with 
prior events. The detailed written summary will be provided to the DSMB, IRB, and sponsor.  
 
In addition, the DSMB Report addressing the following information will be submitted to the IRB at 
the time of continuing review annually or more often as required. 
 
 
5.6.3 Adverse Events Reporting Timeline 
 
The investigators or site staff are responsible for detecting, documenting and reporting events 
that meet the definition of an AE or SAE.  AEs will be collected from the start of study treatment 
and until the follow up contact.  SAEs will be collected over the same time period as stated 
above for AEs. However, any SAEs assessed as related to study participation (e.g., study 
treatment, protocol-mandated procedures, invasive tests, or change in existing therapy) or 
related to a GSK concomitant medication, will be recorded from the time a subject consents to 
participate in the study up to and including any follow up contact.  
 
The investigators will report life-threatening or fatal unexpected adverse events associated with 
the use of the study drug or procedures to the DSMB, and the IRB within 24 hours of discovery 
of the incident with subsequent follow-up submission of a detailed written report. 
 
All SAE will be reported via email notification within 24 hours of awareness to the following 
sponsor (GSK) contacts including:  
1) ISS Chairperson 
2) ISS Managing Director 
3) GMAL or designee 
4) LOC Physician 
5) LOC Safety Contact 
6) LOC Study Accountable Person 
7) GCSP Safety Physician 
8) GCSP Safety Scientist 
9) US.NAPS@gsk.com  
 
Serious (but not fatal or life-threatening) and unexpected adverse events associated with the use 
of the study drugs or procedures must be reported to the DSMB and the IRB within 5 working 
days with subsequent follow-up submission of a detailed written report.

Individual subject-specific stopping rules: A study participant will be discontinued from 
further study drug treatment/Intervention(s) administration if any of the following occur: 
 
Any clinical adverse event, laboratory abnormality, intercurrent illness, other medical 
condition or situation occurs such that continued participation in the study would not be in 
the best interest of the participant. 
 
An unexpected fatal or life-threatening adverse event, which requires discontinuation of 
study treatment. 
 
Patients who develop acute exacerbations that require an addition to their lung 
medications, or a hospitalization, will be terminated from the study.  Any subject who 
develops new conditions or statuses that would have been an exclusion criterion, will be 
terminated from the trial.   
 
Request by the subject to withdraw from the study.

used instead of the primary endpoint since the primary endpoint is not a clinical marker of 
efficacy.  The DSMB and sponsor (GSK) will have responsibility for invoking a study-wide 
stopping rule based on their evaluations of the data.   
 
 
5.6.5 Parameters to be Monitored 
The following progress will be monitored throughout the course of the research to ensure the 
safety of subjects as well as the integrity and confidentiality of their data. 
 
• 
An evaluation of the progress of the research study, including subject recruitment and 
retention, and an assessment of the timeliness and quality of the data. 
 
• 
A review of collected data (including adverse events, unanticipated problems, and subject 
withdrawals) to determine whether there is a change to the anticipated benefit-to-risk 
assessment of study participation and whether the study should continue as originally 
designed, should be changed, or should be terminated. 
 
• 
An assessment of external factors or relevant information (eg. Pertinent scientific 
literature reports or therapeutic development, results of related studies) that may have an 
impact on the safety and study participants or the ethics of the research study. 
 
• 
A review of study procedures designed to protect the privacy of the research subjects and 
the confidentiality of their research data. 
 
 
5.6.6 Frequency of Monitoring 
 
The PIs will review subject safety data as it generated. The PIs and research staff will meet or 
converse bi-monthly when the study is being initiated, and then thereafter at least at monthly 
intervals, or more frequently if necessary, to re-evaluate study goals, subject recruitment, data 
coding and retention, documentation and identification of adverse events, complaints, and 
confidentiality of subjects. There will be an evaluation of the progress of the research study, 
including assessments of data quality, time lines, participant recruitment, accrual, and retention. 
The PIs will also review the outcome and adverse event data to determine whether there is any 
change to the anticipated benefit-to-risk ratio of study participation and whether the study should 
continue as originally designed or should it be re-evaluated and changed. 
 
 
6. STUDY ADMINSTRATION 
 
6.1 REGULATORY AND ETHICAL CONSIDERATIONS 
 
The clinical study will be conducted in accordance with the IRB-approved clinical protocol; 
International Conference of Harmonization (ICH) guidelines on Good Clinical Practice, and 
relevant policies, requirements, and regulations of the IRBs, and applicable federal regulations, 
including those required under an IND exemption. 
 
The clinical trial will be registered with ClinicalTrials.gov to comply with Section 801 of Public 
Law 110-85. 
 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD

The investigators will make certain that appropriate processes and procedures are in place to 
ensure that ongoing questions and concerns of enrolled subjects are adequately addressed and 
that the subjects are informed of any new information that may affect their decision to continue 
participation in the clinical study.  In the event of substantial changes to the clinical study or the 
risk-to-benefit ratio of study participation, the investigators will obtain the informed consent of 
enrolled subjects for continued participation in the clinical study. 
 
 
6.2  PROTOCOL DEVELOPMENT 
 
6.2.1 Activation of a protocol 
The PI and the Co-PI are responsible for the coordination, development, and approval of the 
protocol as well as its subsequent amendments, and reporting serious adverse events, violations 
and deviations per IRB guidelines. 
 
To meet these requirements, the PI and the Co-PI will be responsible for the following minimum 
standards: 
 
• 
Commit to the provision that the protocol will not be rewritten or modified by anyone other 
than the PIs. 
• 
Ensure that there is only one version of the protocol.  
• 
Oversee the development of data collection forms (case report forms).  
 
 
6.3 PROTOCOL MANAGEMENT 
 
6.3.1 Protocol distribution 
 
The Contact PI will distribute the final approved protocol and any subsequent amended protocols 
to all study staff.    
 
 
6.4 INFORMED CONSENT REQUIREMENTS 
 
 
 
All study participants in this study will be provided a consent form describing the study and 
providing sufficient information for participants to make informed decisions about their 
participation in this study.  The study participant MUST be consented with the IRB approved 
consent form before the participant is subjected to any study procedures.  The approved consent 
form MUST be signed and dated by the study participant and the investigator or other qualified 
study staff member obtaining the consent. 
 
 
 
6.5 IRB DOCUMENTATION 
 
6.5.1 IRB Renewal Approval 
Annual IRB renewal approval is required in order to continue research and recruit participants 
onto a protocol.  There is no grace period for continuing approvals. 
 
 
6.6  QUALITY CONTROL AND QUALITY ASSURANCE  
 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD 
_________________________________________________________________________________________________________

To ensure the human subject protection, study procedures, laboratory, study intervention 
administration, and data collection processes are of high quality and meet GCP and, when 
appropriate, regulatory guidelines, the DSMB and/or sponsor may conduct a quality assurance 
audit (site monitoring) of the site records at any time during or after completion of the study.  Audits 
of a random selection of data, and all protocol consents will also be reviewed.   
 
Monitoring will be scheduled periodically throughout the conduct of the study to assure compliance 
with the approved protocol, and to verify the completeness and accuracy of study data.  Monitoring 
also aids in identifying any research-related problems for the investigator to correct.  A brief written 
report on each audit or site visit will be prepared by the auditor(s) and sent to the sponsor, DSMB, 
and PIs after each site visit. 
 
 
6.7  DATA HANDLING AND RECORD-KEEPING 
 
6.7.1 Data recording/Case Report Forms    
 
Case report forms (CRFs) are the primary data collection instruments for the study.  All data 
requested on the CRFs must be recorded, and any missing data must be explained.  If a space is 
left blank because the procedure was not done or the question was not asked, “N/D” must be noted.  
If the item is not applicable to the individual case “N/A” must be noted.  All entries must be printed 
legibly in black ink on the paper case report forms.  In the event of any entry errors, corrections 
must be made by drawing a single straight line through the incorrect entry, writing the initials of the 
person making the correction, recording the date when the correction is being made, and entering 
the correct data above the strike through.    
 
Data elements that are extracted from the medical record (such as participant history or official 
clinical interpretations of images, pathology, or surgery results) and recorded on the case report 
forms (CRFs) will be audited against the appropriate component of the medical record.  The 
investigator will review, approve and sign/date each completed CRF; the investigator’s signature 
serving as attestation of the investigator’s responsibility for ensuring that all clinical and 
laboratory data entered on the CRF are complete, accurate and authentic.   
 
Source Data are the clinical findings and observations, laboratory and test data, and other 
information contained in Source Documents.  Source Documents are the original records (and 
certified copies of original records); including, but not limited to, hospital medical records,  
physician or office charts, physician or nursing notes, subject diaries or evaluation checklists, 
pharmacy dispensing records, recorded data from automated instruments, x-rays, etc.  
Information recorded on the CRF must be consistent with the Source Data recorded on the 
Source Documents or discrepancies must be explained. 
 
Source data are found in all information, original records of findings, observations, or other 
activities in a clinical trial necessary for the reconstruction and evaluation of the trial.  Source 
data are contained in source documents.  Source documents represent the first recording of any 
observations made or data generated about a study participant while he or she is enrolled in a 
clinical trial. Source documents for each study participant substantiate the data that are 
submitted in the CRF. 
 
If data is abstracted from medical charts that are not filed at the investigative sites (e.g. hospital 
charts), copies of these records should be filed in the research chart.  However, every attempt 
must be made to obtain all records/charts that were used to abstract any study data for this 


BOTEGA  V.2.5 , June 19, 2020                                                                                                              Steven R. Duncan, MD 
_________________________________________________________________________________________________________ 
45 
 
protocol at the time of the audit visit.  This will prevent any discrepancies and the inability to 
verify the document and the data reported.   
 
The CRFs must be kept current to reflect subject status at each phase during the course of the 
trial. In all cases, subjects must not be identified on the CRF by name.  Appropriate coded 
identifications (i.e. Subject ID number) will be used. Every effort will be made to collect complete 
data for each study visit. Causes of missing data will be fully documented. With respect to safety 
evaluation, it is not planned to impute missing data. 
 
6.7.1 Record maintenance and retention   
 
Following closure of the study, the investigator must maintain all site study records in a safe and 
secure location. The records must be easily accessible when needed (e.g., for audits or 
regulatory inspections) and must be available for review in conjunction with assessment of the 
facility, supporting systems, and relevant site staff. 
 
Where permitted by local laws/regulations or institutional policy, some or all of the records may 
be maintained in a format other than hard copy (e.g., microfiche, scanned, electronic); however, 
caution must be exercised before such action is taken. The investigator must ensure that all 
reproductions are legible and are a true and accurate copy of the original. In addition, they must 
meet accessibility and retrieval standards, including regeneration of a hard copy, if required. The 
investigator must also ensure that an acceptable back-up of the reproductions exists and that 
there is an acceptable quality control procedure in place for creating the reproductions. 
 
The minimum retention time will meet the strictest standard applicable, as dictated by local 
laws/regulations, and/or institutional requirements. 
 
 
7  COSTS AND PAYMENTS 
 
7.1  COSTS 
 
Staff (Coordinator and laboratory technician) salaries will be borne the sponsor.  The sponsor will 
also pay for study-specific assays, tests, procedures, and therapeutics.   
 
 
7.2  PAYMENTS 
 
Participation in this protocol is completely voluntary. Subjects will be compensated a maximum of 
$1425 for their participation in this research study.  Parking will be provided at no cost while 
at the research clinic.
