OBJECTIVES 
 
1.1 
Primary Objectives – The primary objective is the evaluation of the effect of Aspirin as a 
chemopreventive agent for lung cancer. Particularly, the efficacy of Aspirin in reduction of size and 
number of CT-detected lung subsolid nodules will be evaluated in high-risk asymptomatic subjects 
currently undergoing CT screening programs at the European Institute of Oncology (EIO) and at MD 
Anderson Cancer Center (MDACC).  
In addition, we will include subjects undergoing CT outside the context of a screening program with a 
subsolid nodule confirmed by pulmonary CT scan (qualifying scan).  
The efficacy will be evaluated in a person-specific analysis.  
 
1.2 
Secondary Objectives – Secondary objective of the study will be the modulation of biological 
markers after treatment and the correlation of these findings with modification of lung nodules diameters. 
In particular we will evaluate the effect of Aspirin on a signature of serum microRNA correlated to 
subsolid nodules. Other secondary endpoints will be the per-lesion analysis including the evaluation of 
lung nodule density before and after treatment, the number and size of non target lesions including solid 
nodules and evaluation of response according to modified RECIST criteria. Additional biomarkers will 
include the modulation of ultrasensitive circulating hs-CRP, the evaluation of urinary cotinine as marker 
of tobacco exposure and investigation of the potential effect of aspirin according to its concentration, the 
measurement of urinary prostaglandin metabolites (PGEM) and leukotriene (LTE4), both normalized 
normalized to urinary creatinine concentration. Serum concentration of thromboxane B2 (TXB2) will be 
determined as a measure of compliance. We will also evaluate the tolerability of Aspirin at dose of 100 
mg/day.

BACKGROUND 
 
2.1 
Lung cancer 
 
Lung cancer is one of the most common cancers in humans and the annual incidence continues to grow. 
The burden caused by lung cancer is enormous worldwide and largely due to tobacco use. In Western 
countries smoke cessation campaigns and stricter regulations are beginning to multiply. This strategy will 
surely achieve good results in the future. However, there are still age and gender groups (the younger and 
women) who are at present more reluctant to avoid smoking, while the smoking epidemic is hitting the 
underdeveloped countries more and more alarmingly. In the meanwhile, new screening modalities are 
under evaluation: the most promising is currently spiral low-dose CT scan (ld-CT). 
 
2.2 
Aspirin 
 
Aspirin, the first non steroidal anti-inflammatory drug (NSAID) identified, may have anti-cancer 
properties, especially for diseases whose etiology implicates the role of chronic inflammation, such as 
colorectal and lung cancer. The anti-inflammatory effect of NSAIDs operates through inhibition of 
prostaglandins via suppression of cyclooxygenase-1 (COX-1) and COX-2. The most convincing evidence 
of this effect is derived from several recently published meta-analyses of aspirin in the prevention of 
cardiovascular events which showed that daily aspirin reduced the incidence of colorectal cancer and 
several other cancers and reduced metastases1-3. In 2011, Rothwell et al.4 pooled data from 8 double-blind 
randomized controlled trials of daily aspirin and analyzed the effect of aspirin on cancer mortality as 
secondary endpoints. The 20-year risk of death due to all cancers was consistently lower in the aspirin 
groups than in the control groups and the benefit increased with duration of treatment.

Lung cancer-speciﬁc mortality rates were reduced by 29% (95% CI, 11-42) in the aspirin group in the 20-
year period after the trial commenced4. No trend with dose (above 75 mg/day) was observed, but the 
effect on all cancers was more evident in adenocarcinomas and was present in both smokers and 
nonsmokers4. Several further observational studies have been published. In a prospective cohort study, 
total NSAID use was associated with a small reduction in risk of lung cancer, which was strongest for 
adenocarcinoma in men, and in long-term former smokers5. A suggestion of a protective effect of low-
dose aspirin was seen in the Women’s Health Study6. A hospital-base case-control study found that lung 
cancer risk was significantly lower for aspirin users compared to non-users and prolonged duration of use 
was associated with reduced lung cancer risk. Risk reductions were observed in both sexes, but significant 
dose-response relationship were only seen among male participants7. 
Controversy remains regarding the most appropriate long-term daily dose of aspirin in the prevention 
setting. The mechanisms by which aspirin reduces the risk of cancer are not clear. COX-2 is thought to be 
the isoform most commonly implicated in carcinogenesis, but at the low doses (80-325 mg), aspirin has 
little activity against this isoform8. Aspirin is, in fact, 170 fold less effective at inhibiting COX-2 than 
COX-19. Nonetheless, aspirin may suppress the expression of COX-210, and it may also have 
antineoplastic effects that are unrelated to cyclooxygenase11,12. Since the 81-mg dose and the 325-mg dose 
appear to suppress colorectal prostaglandin levels to a similar extent13-15, we could postulate that the two 
doses may have equivalent potency through COX-related mechanisms. The major risk of aspirin, as with 
other NSAIDs, is the risk of bleeding. Although the antiplatelet effects of aspirin likely contribute to an 
increase in the risk of bleeding, as highlighted by an increased risk of hemorrhagic stroke of 0.2 events 
per 1000 patient-years16, the majority of the increased bleeding has a gastrointestinal tract etiology. The 
influence of aspirin on gastric prostaglandin levels is dosage-dependent, with almost 50% inhibition at 
just 30 mg/d, but maximal inhibition requires approximately 1300 mg/d17. Consistent with these data, all 
conventional dosages of aspirin are associated with an increased bleeding risk. In a clinical trial in which 
1,121 patients with a recent history of histologically documented adenomas were randomly assigned to 
receive placebo (372 patients), 81 mg of aspirin (377 patients), or 325 mg of aspirin (372 patients) daily, 
the risk of bleeding was not a substantial problem and the risk of death and serious bleeding were similar 
among the groups18. In a case-control study of patients admitted with gastrointestinal bleeding, the odds 
ratio (OR) for admission with a bleeding ulcer was increased among aspirin users regardless of dosage19. 
Treatment with a 75-mg/d dosage of aspirin was associated with an odds ratio of 2.3 for a bleeding ulcer 
(95% CI, 1.2-4.4), whereas 300 mg/d increased the OR to 3.9 (95% CI, 2.5-6.3).  
 
2.3 
Rationale 
 
With the evolution of helical CT technology, CT screening for early detection of lung cancers is under 
evaluation in high risk individuals (former and current heavy smokers) with encouraging results20-22. At 
the EIO, a single center screening trial recruited 5,202 high-risk volunteers (both current or former 
smokers) to undergo an annual multidetector low dose CT (ld-CT) for 5 or more years, beginning in 
200421,23. The screening ld-CT, a non invasive test with low radiation exposure and no contrast medium, 
affords the opportunity to serially examine the peripheral lung for the first time, albeit with the limitation 
that small lesions cannot be biopsied and thus their identity remains unknown.  
In September 2012, a new multicenter screening program has been launched at the EIO (Cosmos 2) with 
the aim of enrolling 10,000 high-risk individuals in 6 centers in Italy in a one-year period, with the goal of 
recruiting 5000 at the EIO. The Cosmos protocol requires once yearly low-dose CT for 5 years. One of 
the main objective of the study is the validation of a serum signature of 34 circulating microRNA able to 
predict with high sensitivity the presence of an asymptomatic lung cancer and to validate the Cosmos risk 
model24 on an independent cohort of high risk individuals to better select the target population for 
screening and the optimal screening interval. The population enrolled in the Cosmos 2 will represent the 
major source of potentially eligible subjects for the chemoprevention study.

In the meantime, two other screening programs are still ongoing at the EIO with annual ld-CT scans 
(Cosmos 1 and a pilot study) and they represent an additional source of potential participants. 
Unfortunately, the high rate of benign nodules and issues of making a differential diagnosis are critical 
factors that currently hamper introduction of large-scale screening programs. Small pulmonary nodules 
are, in fact, a frequent finding in the subjects submitted to ld-CT for early detection of lung cancer and 
have no clinical implications. Our data have demonstrated an incidence of undetermined lung nodules in 
more than 50% of high risk individuals21. The nature of these nodules remained uncertain but it is 
reasonable that some of them could represent precancerous lesions. In particular, literature suggests that 
ground glass opacities (GGO), as compared with solid nodules, can represent either localized 
bronchioloalveolar carcinoma without foci of active fibroblastic proliferation or atypical adenomatous 
hyperplasia20 which is a known putative adenocarcinoma precursor lesion25. The possibility to measure 
the nodule density in GGO lesions is an additional tool to monitor these preneoplastic lesions26. 
The actual identity of ld-CT detected GGO cannot be ascertained without histologic analysis, but this is 
the category of nodule that is most likely to represent atypical alveolar hyperplasia, the putative precursor 
of pulmonary adenocarcinoma27. Kim et al. reported that of 53 persistent GGO in 49 patients who 
underwent resection, 68% proved to be bronchoalveolar carcinoma, 7.5% were adenocarcinoma with 
predominant brochoalveolar components, 6% were atypical adenomatous hyperplasia, and 19% were 
nonspecific fibrosis or organizing pneumonia28. Similarly, Ohtsuka et al. reported that of 26 patients who 
underwent resection, bronchoalveolar carcinoma was diagnosed in 10 patients (38%), atypical 
adenomatous hyperplasia was diagnosed in 15 patients (58%), and focal scar was seen in 1 patient (4%)29. 
Although criteria such as size, the presence of air bronchograms, and nodule sphericity on CT scan have 
been used to differentiate carcinomas from atypical alveolar hyperplasia, histological analysis remains the 
gold standard for definitive categorization of nodules and there continues to be debate regarding the 
overlap between small bronchoalveolar carcinomas and atypical alveolar hyperplasia30,31. Since resected 
nodules represent lesions that are suspicious enough to merit surgery, it is possible and even likely that 
the smaller nodules identified in the context of our ld-CT screening study represent less advanced 
neoplasia than described in the above cited studies as well as non-neoplastic etiologies. 
 
In 2010 we published the results of the Budesonide trial (MDA05-5-01), a randomized phase IIb study 
that evaluated the role of inhaled Budesonide in the shrinkage of CT detected undetermined lung nodules. 
The study showed an effect of the treatment only on non solid nodules and a trend in partially solid 
nodules32. A 5-year follow up of the nodules with annual low dose CTs showed that the effect of 
treatment was maintained years after treatment and was significant for non solid and partially solid 
nodules (unpublished data). Specifically, after 60 months the mean reduction of maximum diameter in the 
treated arm were 2.65 mm and 0.69 mm in the non-solid and partially solid lesions, respectively. 
 
We concluded that screen-detected non solid and partially solid nodules represent a good target to test 
chemopreventive agents and that the role of Budesonide deserves further investigation. 
 
The University of Texas MD Anderson Cancer Center launched its Lung Cancer Screening Program in 
2011. To date, nearly 800 patients have been screened averaging approximately 20-30 screened patients 
per month. An additional resource for screening CTs is the active protocol entitled “Biospecimen Banking 
and Biomarker Validation for Lung Cancer Early Detection in Cohort Receiving Low Dose Helical Computed 
Tomography Screening” which has 194 patients currently enrolled. Although literature indicates the 
frequency of eligible lesions is approximately 30%, MDACC’s experience is slightly less at 10% (2-3 
patients per month) identified by low dose screening CT scan. From this population, it is anticipated the 
Lung Cancer Screening program may enroll less than 1 eligible patient per month after evaluation of other 
eligibility criteria. However, with the inclusion of lesions identified by diagnostic CT scan, MDACC’s 
large cancer survivor population offers a larger pool of potentially eligible patients undergoing CTs for 
surveillance.

Based on the recent knowledge on the chemopreventive effect of Aspirin on lung cancer, we intend to 
evaluate the effect of low dose Aspirin (100 mg/day) on non solid and partially solid nodules identified in 
high risk volunteers submitted to annual low dose CTs among the ongoing screening programs at EIO and 
MDACC.   
In addition, we will include subjects undergoing CT outside the context of a screening program with a 
subsolid nodule confirmed by pulmonary CT scan.  
 
Rationale for Biomarkers selection 
microRNA: Modulation of biological markers after treatment and the correlation of these findings with 
modification of lung nodules diameters will be investigated as secondary endpoints. In particular, we have 
recently identified serum circulating microRNA (miRNA) able to accurately predict the presence of lung 
cancer during early stages disease33. The test was accurate enough to capture the onset of the disease in 
patients of whom serum samples were available before and after diagnosis of lung cancer by ld-CT. The 
same signature was also able to identify the premalignant GGO lesions among Cosmos 1 participants 
(unpublished data). In brief, we screened a group of 27 individuals with GGO lung nodules and applied 
the miRNA test. Twenty-four out of 27 were positives to the test (~89%). Furthermore, the average 
miRNA-test risk score of the GGO group was 12.5 while the average score of two other groups of 
individuals with solid nodules (N=25), or without nodules (N=25), were -2.2 and -4.4 respectively (p 
<0.0001; Student’s t-test). This confirmed the validity of the miRNA-test to predict the presence of GGO 
lesions as well as early stages lung cancer, and suggest that active or passive release in the blood of 
specific miRNA species is already present in lung premalignant lesions. 
The advantages of such a test compared to ld-CT are the potential for an easy applicability on a 
population-wide scale, the high potential for implementation of screening on a nation-wide scale, the 
absence of risks related to ionizing radiations, and the reduced costs 
As regards the technical aspects we have developed a fully automatized procedure based on low-density 
qRT-PCR array that allows the screening of expression of ~800 different miRNA species and using less 
than 300l of serum. This will give us the opportunity to test every known miRNA present in the serum 
and to perform an accurate analysis of their quantities.  
We intend to apply the very same technology to identify serum miRNAs predictive of the effect of aspirin 
treatment in patients with GGO lung nodules. 
 
C-reactive Protein: Inflammation has been hypothesized to increase the risk of cancer34 although data 
from epidemiologic study are sparse. Many inflammatory conditions are well-known cancer precursors 
(Barrett’s esophagus, chronic gastritis, hepatitis, pancreatitis, and ulcerative colitis). So, early correction 
of inflammatory conditions by chemoprevention may be theoretically very useful. C-reactive protein 
(CRP), a member of the pentraxin family of proteins involved with pattern recognition in innate 
immunity, is the principal downstream mediator of the acute-phase response and is primarily derived via 
the interleukin 6-dependent hepatic biosynthesis35. Moreover, ultrasensitive CRP (hs-CRP) is an known 
index of subclinical systemic inflammation associated with increased risk for cardiovascular events and 
diabetes. Elevated levels of hs-CRP have been linked to colon cancer development and a recent meta-
analysis36 including 1,918 lung cancer cases points to its implication also with lung cancer risk. 
Given our previous experience in measuring hs-CRP in subjects at higher risk for breast cancer37, we are 
interested in investigating change in hs-CRP also in subjects at higher risk of lung cancer. 
 
Cotinine: Measurement of cotinine, the nicotine metabolite, provides an accurate estimate of recent 
tobacco smoke exposure and are able to account for individual differences in smoking practices, such as 
depth of inhalation and how much each cigarette is smoked38,39. 
 
Prostaglandin (PGEM): Prostaglandin synthesis is driven by the two COX. Prostaglandin E2 is the most 
abundant prostanoid in the human body and it has been implicated in various tumorigenic processes and

induces proliferation by activating at least two signalling pathways: Ras–Erk and glycogen synthase 
kinase-3β (GSK3β)–β-catenin in colon and lung cancer cells40. Circulating prostaglandin E2 is rapidly 
cleared by a single passage through the lungs and measurement of the metabolites is necessary to provide 
a reliable estimate for its actual production. 
 
Leukotriene E4 (LTE4): Leukotriene E4 is an urinary metabolite indicating activation of the 
lipoxygenase pathway41. To perform urine analysis for LTE4, we will show relationship between acetyl-
salicylic acid (ASA) and the LTE4 shunt in healthy smokers. 
 
Thromboxane B2 (TXB2): Thromboxane B2 is a biologically inactive metabolite of Thromboxane A2, 
an arachidionate metabolite with potent platelet aggregation activity and prothrombotic properties, that is 
rapidly hydrolyzed to TXB2. TXB2 is thus a suitable markers for monitoring platelet function and 
assessment of aspirin compliance. 
 
 
3. 
SUMMARY OF STUDY PLAN 
 
We will conduct a double-blind placebo-controlled phase IIb study in which participants will be 
randomized to receive either Aspirin (100 mg/day) or placebo for 12 months. 
 
A total of 128 subjects will be accrued (randomized to drug or placebo); 64 per arm in a 3.5 year time 
period. 
 
Participants will be men and women, current or former smokers, with undetermined subsolid lung 
nodules detected at low dose screening CT scan (without constrast medium) running at the EIO and 
MDACC. In addition, we will include subjects undergoing CT outside the context of a screening 
program, providing a subsolid nodule confirmation by a CT scan. Participants will be given 100 mg 
Aspirin daily or placebo for 12 months.  
 
The primary endpoint will be the shrinkage of GGO and partially solid lung nodules after one-year 
treatment per-subject analysis.  
 
Secondary endpoints will be the modulation of biological markers after treatment and the correlation of 
these findings with modification of lung nodules diameters. In particular we will evaluate the effect of 
Aspirin on a signature of serum miRNA correlated to subsolid nodules. Other secondary endpoints will be 
the per-lesion analysis including the evaluation of lung nodule density before and after treatment and the 
number and size of non target lesions. Additional biomarkers will include the modulation of hs-CRP, the 
evaluation of urinary cotinine as marker of tobacco exposure and investigation of the potential effect of 
aspirin according to its concentration, the measurement of urinary prostaglandin metabolites (PGEM) and 
urine leukotriene E4 (LTE4) both normalized to urinary creatinine concentration. Serum concentration of 
thromboxane B2 (TXB2) will be determined as a measure of compliance. We will also evaluate the 
tolerability of Aspirin at dose of 100 mg/day. 
 
Complete physical exam and safety lab tests will be performed at 0, 6 and 12 months. Phone contact will 
occur at month 1, 3, 9 and 13 (i.e, one month after treatment completion).  
 
Biomarkers: blood and urine will be collected at 0, 6 and 12 months 
 
Lung lesions will be measured with a CT scan at 0 and 12 months. Both standard dose and low dose CT 
scans are allowed provided that the same procedure is used at both time points.

Inclusion Criteria 
 
4.1.1 
Asymptomatic current or former smokers (having stopped within the last 20 years). See Appendix 
D 
 
4.1.2 
Age > 50 years (risk of lung cancer in subjects under 50 is low thus screening is not indicated by 
actual international guidelines).

4.1.9 The effects of Aspirin on the developing human fetus at the recommended therapeutic dose are 
unknown. For this reason and because acetyl salicylic acid (ASA) is known to be teratogenic, women of 
child-bearing potential (from first menstruation to 1 year after last menstruation) must agree to use 
adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and 
for the duration of study participation.  
Should a woman become pregnant or suspect she is pregnant while participating in this study, she should 
inform her study physician immediately.

Subjects with chronic treatment (at least twice/week for more than 3 months) with Aspirin or 
other NSAIDs. 
 
4.2.2 
History of allergic reactions attributed to compounds of similar chemical or biological 
composition to aspirin, NSAIDs, COX2 inhibitors.

4.2.5 
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, 
symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric 
illness/social situations that would limit compliance with study requirements. 
 
4.2.6 
Pregnant women are excluded from this study because Aspirin is an agent with the potential for 
teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in 
nursing infants secondary to treatment of the mother with Aspirin, breastfeeding should be discontinued if 
the mother is treated with Aspirin.

precipitated bronchospasm, patients unwilling or unable to limit alcohol consumption to i.e. ≤ 3 alcohol 
drinks a day. 
 
4.2.9 Participants who in the opinion of the PI will be at higher risk of ASA-related complications.  
 
4.2.10 Participants with known inability to adequately absorb oral medication.  
 
4.3 
Inclusion of Women and Minorities 
 
Both men and women and members of all races and ethnic groups will be eligible for this trial. However, 
given that the distribution of the Italian population mainly consists of white Caucasians (about 93%), we 
expect very few subjects of different ethnic background to be enrolled in the screening. The gender 
distribution among the Cosmos 2 screening population is about 65% and 35% for men and women, 
respectively and we expect a similar distribution in the chemoprevention study. Detailed information 
about distribution is reported in the DCP Protocol Submission Worksheet (PSW).

Recruitment and Retention Plan 
 
The projected number of eligible subjects in the entire cohort of 8,000 individuals undergoing annual 
screening at EIO will be close to 600. Considering that 20% of subjects will be excluded because of 
ongoing treatment with Aspirin, the eligible pool will include about 480 subjects. Accrual rate is expected 
to be no less than 32% of the predicted pool. This percentage is higher than the average recruitment rate 
in chemoprevention trials in healthy subjects (average 10%), but is reasonable given that the population is 
represented by highly motivated volunteers and previous EIO screening compliance has been higher than 
97%. This would allow to consent about 150 people, whose slides will be re-reviewed and re-measured by 
a study dedicated radiologist and pulmonologist. It is expected that approximately 128, or 80% of 
consented individuals, will meet all eligibility criteria for the protocol and will be randomized. Since the 
Cosmos 2 trial is a five year protocol with annual low-dose CT scans, we will have the opportunity to pre-
screen the individuals participating in the Cosmos trial for eligibility and to approach them with the 
present protocol at the time of their next scheduled Cosmos trial-directed CT scan that falls within the 
window of our trial accrual period. Additionally, there will be individulas who develop new small nodules 
for the first time while participating in the Cosmos protocol. Such individuals will return per Cosmos 
protocol for a repeat CT scan in 3 months, and if they meet the inclusion criteria of the present trial after 
the repeat CT scan, they will also be captured. 
 
MDACC launched its Lung Cancer Screening Program in 2011. To date, nearly 800 participants have 
been screened averaging approximately 20-30 screened participants per month. An additional resource for 
screening CTs is the active protocol entitled “Biospecimen Banking and Biomarker Validation for Lung 
Cancer Early Detection in Cohort Receiving Low Dose Helical Computed Tomography Screening” which has 
194 participants currently enrolled. Although literature indicates the frequency of eligible lesions is 
approximately 30%, MDACC’s experience is slightly less at 10% (2-3 participants per month) identified 
by low dose screening CT scan.  From this population, it is anticipated the Lung Cancer Screening 
program may enroll approx. 1 eligible participant per month after evaluation of other eligibility criteria.  
However, with the inclusion of lesions identified by diagnostic CT scan, MDACC’s large cancer survivor 
population offers a larger pool of potentially eligible participants undergoing CTs for surveillance. 
 
Pre-Initiation phase  
 
Both at IEO and MDACC, subjects with persistent subsolid lung nodules detected during any of the 
screening programs are potentially eligible for the trial and will be identified as potential candidates for 
the study by the local Lung Cancer Screening program coordinator.  In addition, subjects with subsolid 
lesions identified outside the context of a screening program will be indicated to the research staff by the 
collaborating radiologists creating a future recruitment resource.  While waiting for the subsequent CT 
scan, the potential candidate will be given a leaflet about the possibility of being contacted for taking part 
in a prevention trial. 
 
Active Recruitment phase 
At EIO, after the evaluation of the CT scan by the radiologist and the thoracic surgeon (Co-PI), and the 
verification of all inclusion criteria, the potential candidate will be contacted by the staff of the Division 
of Cancer Prevention and Genetics for the first phone interview. Each subject will be given a unique and 
consecutive ID number (four digits). The trial design will be explained and availability to participate will 
be asked. Candidates accepting to participate or interested in the study will be invited for a visit at EIO for 
informed consent and baseline visit. 
 
At MDACC, after the evaluation of the CT scan by the thoracic radiologist (Co-PI), and the verification 
of all inclusion criteria, the potential participant will be contacted by the MDACC staff for the first phone

interview. The study design, treatment plan, procedures, follow-up schedule, risks, side effects and

Retention phase (which include adherence strategies)  
The retention phase will be identical between EIO and MD Anderson.  Participants will be scheduled for 
periodic clinic visits (at 0, 6 and 12 months) during which a complete physical exam and lab tests will be 
performed. At months 1, 3 and 9 subjects will be contacted by phone to evaluate self-reported 
compliance/adherence to the treatment and toxicity. In addition they will be reminded about the visit, CT 
scan and blood and urine samples at month 6 and 12.  
 
Recruitment and retention effort will be evaluated routinely by the site coordinator and the study staff. It 
can be modified as necessary to promote rapid accrual and to assure maximally high retention rate of 
participants.

AGENT ADMINISTRATION 
 
Drug will be administered on an outpatient basis. Reported adverse events and potential risks are 
described in Section 6.2.  
 
5.1 
Dose Regimen and Dose Groups 
 
Group 1 
Agent: Aspirin 
Daily doses: one dose of 100 mg once a day 
Duration: one year 
 
Group 2 
Agent: placebo 
Daily doses: one dose once a day 
Duration: one year 
 
5.2 
Aspirin Administration 
 
At EIO, Dr Bonanni (PI) will be responsible for drug administration. He can delegate the colleagues of 
the Division of Cancer Prevention and Genetics (MDs and research nurses) to administer the agent on his 
behalf. 
 
At MD Anderson, Dr Bevers (MD Anderson Site PI) will be responsible for drug administration. She can 
delegate to MDACC site collaborators to administer agent on her behalf as noted in the Delegation of 
Authority log. 
 
Subjects will receive a 7-month supply of the drug/placebo as outlined in the clinical procedure schema 
(see paragraph 7.1. for a detailed description). Each kit contains of 210 tablets (7 bottles of 30 tables 
each) of aspirin 100 mg or placebo. 
Subjects will be advised to take aspirin after food.

Run-in Procedures  
 
No run-in procedure will take place in the present protocol. 
 
5.4 
Contraindications 
 
Aspirin should not be taken by people who are allergic to ibuprofen or naproxen, or who have salicylate 
intolerance or a more generalized drug intolerance to non-steroidal anti-inflammatory drugs (NSAIDs), 
and caution should be exercised in those with asthma or NSAID-precipitated bronchospasm. Owing to its 
effect on the stomach lining, manufacturers recommend people with peptic ulcers, mild diabetes, or 
gastritis seek medical advice before using aspirin. Even if none of these conditions is present, the risk of 
stomach bleeding is still increased when aspirin is taken with alcohol or warfarin. Patients with 
hemophilia or other bleeding tendencies should not take aspirin or other salicylates. Aspirin is known to 
cause haemolytic anemia in people who have the genetic disease glucose-6-phosphate dehydrogenase 
deficiency, particularly in large doses and depending on the severity of the disease. People with kidney 
disease, hyperuricemia, or gout should not take aspirin because it inhibits the kidneys' ability to excrete 
uric acid, and thus may exacerbate these conditions. 
 
5.5 
Concomitant Medications 
 
Other NSAIDs or glucocorticosteroids should be avoided or limited. Any use of systemic or topic 
NSAIDs or glucocorticosteroids should be clearly documented (time, doses, routes, indications) and 
followed regularly. 
 
If a participant requires pain relievers or antipyretics, the use of non-NSAIDs, e.g., acetaminophen, 
should be encouraged. It is not necessary to break the blind in most situations. A protonic pump inhibitor 
(PPI, omeprazole 20 mg/day tablet) will be added during the period of any NSAIDs or 
glucocorticosteroids treatment and will be stopped once NSAIDs or glucocorticosteroids are withdrawn. 
 
Short courses of systemic NSAIDs or glucocorticosteroids (defined as up to 2 weeks at a time) are 
allowed. No more than 1 month total of off-protocol NSAIDs or glucocorticosteroidsis allowed in a 6 
months period. If it is anticipated that continuous NSAIDs or glucocorticosteroids will be needed or if 
more than 1 month of NSAIDS or glucocorticosteroids occurs during a 6 months period, the participant 
will stop study drug. However, since the participant will still undergo his/her yearly scan, they can still be 
assessed in an intent-to-treat analysis and thus do not come off the study. Non systemic 
glucocorticosteroids use is allowed without time restrictions. 
 
All medications (prescription and over-the-counter), vitamin and mineral supplements, and/or herbs taken 
by the participant will be documented on the concomitant medication CRF and will include: 1) start and 
stop date, dose and route of administration, and indication. Medications taken for a procedure (e.g., 
biopsy) should also be included. 
 
5.6 
Dose Modification 
 
Subjects will be asked to maintain the full dose throughout the treatment period. However, should some 
toxicity appears, dose modification will be applied and recorded. 
 
Toxicity will be evaluated at each visit using the most recent version of the NCI terminology criteria 
(CTCAE version 4.0.3, published 06/14/2010).

resumes after reintroduction of full dose, stop drug again until toxicity reaches grade 1 or lower and then 
reduce drug by 50% (100 mg at alternate day) and maintain this dose. No further reductions will be 
permitted and patients with returning toxicities will be removed from the study.

5.7 
Adherence/Compliance 
 
Estimates for patient non-adherence to various medical regimens range from 20% to 100%, and some 
authorities have come to view the difficulty of guaranteeing patient adherence as one of the most serious 
problems facing medical practice today. Recent data from ongoing chemoprevention studies have 
estimated adherence to be between 60% and 100%. The disparity between the highest and lowest 
estimates may largely be attributed to methodology, given that the assessment of adherence remains 
problematic - there is as of yet no 'gold standard' to measure patient adherence. Because no such gauge 
exists, we propose the use of multiple methods of adherence monitoring: subject self-reporting, calendar 
completion and dose count.  
 
Although drug concentration will not be measured in the blood, compliance will be monitored in the 
following ways: 
 
Patient Self-Report: The patient's history, the most direct source of information, is the most widely 
employed measure of a patient's adherence to their medical regimen. However, patient self-reporting has 

DCP Protocol Number MDA2013-01-01

DCP Protocol Template Version 8.3 
–22– 
05/21/2013 
been criticized as being too subjective, with patients tending to over-report their adherence by as much as 
two to fourfold. Positive information is helpful, but false negatives are common. 
 
Calendar completion: Each subject will be provided a 7-month calendar as a reminder of drug intake 
(Appendix B). Each subject will be asked to cross the corresponding day of the calendar (1 cross for each 
tablet, i.e. 1 cross per day). Subjects are asked to fill the calendar and some additional space will be left 
for patient’s notes. Each calendar will be returned at the next scheduled visit. 
 
Dose count: Each subject will receive a 7-month supply of the drug or placebo and will be asked to return 
all full and empty bottles. Compliance will be measured as follows: 
number of tablets taken (i.e., number of tablets given-number of tablets returned)/number of tablets that 
should have been taken during that period of time. 
In cases where the tablets are not returned, the compliance has to be calculated from the calendar. 
 
Serum Thromboxane (TXB2): As an additional measure of compliance, we will evaluate the concentration 
of serum TXB2, a reliable marker of aspirin use42. 
 
The chemoprevention research nurse and the physicians will provide education for subjects, indicating 
when and how should the tablets be administered (general measures to reduce risk of GI adverse effects). 
 
In case of concomitant medications, subjects are asked to contact the chemoprevention staff in order to 
check whether any potential interference is expected. Data on drug suspension or interruption will be 
reported into the CRFs.

Bulk aspirin and matching placebo will be manufactured and supplied by Bayer Europe, using a dose 
currently available on the European market. Packaging and labeling will be performed by Monteresearch 
srl, Bollate, Italy and labeling performed by MRIGlobal for US supplies. 
 
Aspirin is provided to the EIO under a Clinical Trials Agreement (CTA) between Bayer Europe and the 
EIO (see §12.7). 
 
6.4 
Agent Distribution 
 
Agents will only be released by NCI, DCP after documentation of IRB approval of the DCP-approved 
protocol and consent is provided to DCP and the collection of all Essential Documents is complete (see 
DCP website for description of Essential Documents).  
 
EIO 
Bayer Europe will release active drug and matching placebo to the EIO only after documentation of IRB 
approval and a specific contract has been signed by the EIO representative. The distributor will be Bayer 
Europe. 
 
Bayer will ship the unmasked drug to the external Pharmacy service appointed by the EIO 
(Monteresearch srl, Bollate, Italy) that will be responsible for re-labeling and packaging the bottles 
according to protocol requirements. Each bottle contains 30 tablets. The pharmacy service will provide 
blinded study agent to investigators with a current FDA form 1572 filed with DCP. Drug will not be used 
or distributed out of the present protocol.  
 
MD Anderson 
For US clinical supplies, the packaged drug will be labeled in US English by the NCI DCP repository, 
MRIGlobal. The NCI DCP repository will distribute the clinical material to MDACC. 
 
NCI, DCP-supplied agents may be requested by the Investigator (or their authorized designees) at each 
Organization. DCP guidelines require that the agent be shipped directly to the institution or site where the 
agent will be prepared and administered. DCP does not permit the transfer of agents between institutions 
(unless prior approval from DCP is obtained). DCP does not automatically ship agents; the site must 
make a request. Agents are requested by completing the DCP Clinical Drug Request form (NIH-986) (to 
include complete shipping contact information) and faxing or mailing the form to the DCP agent

Agent Accountability  
 
The Investigator, or a responsible party designated by the Investigator, must maintain a careful record of 
the inventory and disposition of all agents received from DCP using the NCI Drug Accountability Record 
Form (DARF) or an institutionally-approved accountability system. The Investigator is required to 
maintain adequate records of receipt, dispensing and final disposition of study agent. Include on receipt 
record from whom the agent was received and to whom study agent was shipped, date, quantity and batch 
or lot number. On dispensing record, note quantities and dates study agent was dispensed to and returned 
by each participant. At EIO, this responsibility has been delegated to EIO Pharmacy. At MD Anderson, 
this responsibility has been delegated to MDACC Investigational Pharmacy.  
 
6.6 
Packaging and Labeling  
 
Aspirin and matching placebo will be provided to EIO by Bayer Europe as a bulk shipment, but labeled 
and packaged by an external Pharmacy where they will be stored until delivery. An undisclosed 
randomization list will be provided by the statistician to the dedicated Pharmacist. Each package consists 
of a 7-month supply of the drug or placebo. Each box contains seven bottles with 30 tablets each. Each 
box will be labeled with the following information: EIO study number (S-XXX), randomization number 
(3 digits), PI’s name and phone number, number of total doses, daily dose and schedule, lot numbers and 
expiring dates, specific instruction such as storage temperature, indication to keep the bottle out of reach 
of children. Subject’s identification number will not be reported on drug packages. The same instructions 
will be stuck in the external part of the box package. Half of the label will be removed from the box and 
stuck into the drug delivery CRF to confirm appropriate drug has been administered to the subject. 
 
For clinical supplies in the US, the NCI, DCP repository (MRIGlobal) will perform the product labeling, 
using US English labels, and will store the product for distribution to MDACC. 
 
6.7 
Storage 
 
Study drug will be stored in a secure location, at controlled room temperature (59°F and 86°F) under low 
humidity. 
 
6.8 
Registration/Randomization 
 
Baseline/ Registration into the DMI Database:  
Participants will be screened, consented and, once informed consent has been signed, participants will be 
registered into the DMI database.  The DMI database will assign a participant’s PID upon completion of 
the registration process. 
 
Randomization:  
Participants will be assigned a randomization number once the following has been accomplished: 
eligibility has been verified at the site level, eligibility has been confirmed by the site PI, and eligibility 
CRF has been entered into the DMI web application.  The randomization number will be generated by the 
database and assigned to the participant. Refer to Section 13.2 for details of randomization.  
 
Baseline/Registration/Randomization into site-specific databases: 
The DMI is the database of record for the study. Registration and randomization should occur per the 
procedures outlined above. If the site staff need to enter study data into site-specific electronic databases 
per their institutional requirements, they should do so in accordance with their institutional policies and 
procedures.

Appropriate CRFs must be completed for any participant who signs an informed consent. If a consented 
participant is a screen failure and deemed ineligible, the following CRFs must be completed: 1) the 
Registration CRF with the eligibility box checked “no”, 2) the Inclusion and Exclusion CRFs showing 
why the participant is ineligible, 3) the Off-Study CRF, 4) the Adverse Event CRF, 5) the Concomitant 
Medication CRF and 6) the Verification CRF. If no Adverse Event and/or Concomitant Medications were 
assessed by the time the participant is deemed ineligible, the “NONE” box will be checked to complete 
both CRFs. All participants who sign an informed consent must formally go off study. All participant 
registration information will be entered into DMI. If a participant experiences a serious adverse event 
during the screening process, an SAE form must be completed. 
 
6.9 
Blinding and Unblinding Methods 
 
 
Participants will be blinded to aspirin or placebo. 
 
The Statistician and the Study Pharmacist will not be blinded to Aspirin or placebo. 
 
All other Investigators will be blinded to Aspirin or placebo. 
 
The MDACC Data and Safety Monitoring Board will also be blinded unless unblinding is 
warranted (the reasons for unblinding are outlined below). 
 
All participants will take 1 tablet per day of aspirin/matching placebo. 
 
Study assignments will be unblinded to the Study Investigators and Site Coordinators after all of 
the data are collected and the study database has been locked. Unblinding will also occur if the 
participant’s physician deems that unblinding is necessary, such as in the case of unacceptable toxicity 
thought to be related to the study agent or progressive disease, or if the participant becomes pregnant. 
 
Unblinding will only take place after consultation with the NCI, DCP Task Order Monitor Eva 
Szabo, MD. 
 
If unblinding is indicated prior to the completion of the study, it will be conducted as follows: 
 
The Site PI contacts the Protocol Chairman (the Protocol Principal Investigator) and 
requests the participant’s treatment status be unblinded. 
 
The Protocol Chairman (the Protocol Principal Investigator) contacts the NCI, DCP Task 
Order Monitor (Medical Monitor) and requests the participant’s treatment status be 
unblinded. The Protocol Chairman then conveys the Task Order Monitor’s decision to the 
Site PI. The Site PI then proceeds with unblinding as written out below.  
 
If the NCI Task Order Monitor cannot be reached and the participant requires emergency 
care, the Protocol Chairman (the Protocol Principal Investigator) may authorize the site 
PI to break the blind. 
 
If the Site PI is unable to reach the Protocol Chairman and the participant requires 
emergency care, then the Site PI must proceed with unblinding as written out below.  
 
The Site PI requests the participant’s treatment status be unblinded by the research 
pharmacist (or designated individual responsible for dispensing drug). 
 
The Site PI officially takes the participant off-study.  
 
The date and reason for breaking the blind must be submitted by the Site PI to the 
Protocol Chairman, Bernardo Bonanni, MD, as soon as possible.  
 
It is the responsibility of the Study Chairman to report the date and reason for breaking the blind to 
the NCI Task Order Monitor, Eva Szabo, MD, as soon as possible. 
 
The date and reason for breaking the blind must be submitted by the Study Chairman to 
the MD Anderson Consortium Principal Investigator, Powel H. Brown, MD, PhD, or

Agent Destruction/Disposal  
 
EIO 
At the completion of investigation at EIO, all unused study agent together with all returned tablets will be 
returned to the Pharmacy Service and kept till destruction. Documentation of disposal and destruction will 
be kept until the end of the trial.  
 
MDACC 
At the completion of investigation at MD Anderson, all unused study agent will be returned to NCI, DCP 
Repository according to the DCP “Guidelines for AGENT RETURNS” and using the DCP form “Return 
Drug List”.  The guidelines and the form are available on the DCP website.

CLINICAL EVALUATIONS AND PROCEDURES 
 
7.1 
Schedule of Events 
 
On a weekly basis, all subjects participating in the ongoing IEO screening programs COSMOS 1 and 
COSMOS2 presenting lung nodules are discussed during multidisciplinary meetings involving radiologist 
and clinicians in order to assess the most appropriate monitoring schedule.  
In addition, subjects with eligible subsolid lesions identified outside the context of a screening program 
will be discussed to select potential participants. 
 
Subjects presenting one or more persistent subsolid lung nodules according to the inclusion criteria (see 
par 4.1) are eligible for this chemoprevention trial.  At EIO, potential candidates will be contacted by 
phone by trained personnel illustrating the possibility of taking part in a chemoprevention trial and 
scheduling an appointment for an outpatient visit at the Institute. Randomization should be performed 
within 2 months (i.e., 61 days) from the CT scan. An exception may be done for those subjects with 
nodules who are eligible at the CT scan performed 3 months apart: in order to maintain 12 months 
treatment period, these subjects will be randomized within 6 weeks (i.e. 42 days) and will repeat the CT 
scan 12 months after.  
 
At MDACC, subjects with persistent subsolid lung nodules detected during any of the screening 
programs are potentially eligible for the trial and will be identified as potential candidates for the 
study by the Lung Cancer Screening program coordinator.  In addition, subjects with subsolid 
lesions identified outside the context of a screening program will be provided to the research staff 
by the collaborating radiologists creating a future recruitment resource upon subsequent CT for 
stability.  While waiting for subsequent CT scan, the potential candidate will be given a leaflet 
about the possibility of being contacted for taking part in a prevention trial. Both standard dose and 
low dose CT scans are allowed provided that the same procedure is used at both time points.

CRITERIA FOR EVALUATION AND ENDPOINT DEFINITION 
 
8.1 
Primary Endpoint 
 
For the purposes of the primary endpoint, only sub-solid (non-solid or partially solid) nodules will be 
assessed. Target lesions are defined as non solid or partially solid nodules persistent at least after 3 
months follow up with standard or low dose CT scan, at least 4 mm in size. Non target lesions include 
solid nodules (larger than 3.5 mm), new lesions at baseline (e.g., that were not present on prior CT) or 
non-solid or partially solid nodules < 4mm in size.  
 
The primary end-point will be the difference in sum of longest diameters of baseline target lesions in a 
person-specific analysis. New subsolid lesions identified during follow-up satisfying the same criteria for 
the definition of target lesion will also be included in the analysis. 
 
It has been assumed a -0.2 mm average reduction of the sum of the longest diameter of all non-solid and 
partially-solid lesions at 12 months with respect to baseline in the placebo arm and an expected average 
reduction of -1.0 mm in the aspirin group. 
8.2 
Secondary Endpoints 
  
We will investigate the effects of aspirin on the following secondary end points: (see paragraph 13.5 for a 
detailed statistical analysis):  
 
Evaluation of response according to modified RECIST criteria: 
 
The per-lesion analysis will be done according to the Modified RECIST criteria: 
Complete Response (CR)= disappearance of the lesion 
Partial Response (PR) = shrinkage of >30% of the longest diameter 
Stable Disease (SD) = anything other than CR, PR or PD 
Progressive Disease (PD) = growth >20%, with a minimum increase of 2 mm 
 
The per-subject analysis will be done according to Modified RECIST criteria: 
 
For single nodules a clinical meaningful shrinkage of 30% or more of the longest diameter will be 
considered as a treatment success after one year of treatment as long as there are no new non-solid or 
partially solid nodules or nodules highly suspicious for malignancy or shown to be malignant 
(modification to RECIST criteria). Growth of 20% or more with a minimum of 2 mm, will be considered 
progression.  
 
For multiple lesions the sum of the maximum diameters of all target nodules will be considered, using the 
same parameters to define success and progression (30% or more decrease and 20% or more increase, 
respectively). 
In case of multiple lesions, treatment will be considered successful when a complete response (CR) or 
partial response (PR) occurs according to modified RECIST criteria, while treatment will be considered a 
failure when progression of disease (PD) or stable disease (SD) occurs according to the same criteria. 
Specifically: 
CR: disappearance of all target lesions, + no progression of non-target lesions + no appearance of new 
non-solid or partially solid lesions, and no appearance of new nodules highly suspicious for malignancy

DCP Protocol Template Version 8.3 
–32– 
05/21/2013 
or shown to be malignant (even if solid); 
PR: CR for some target lesions + PR/SD for other target lesions + no PD or new lesions as described in 
CR above; or, PR (i.e., > 30% decrease in the sum of the longest diameter of target lesions, taking as 
reference the baseline sum longest diameter) for target lesions + no PD for non target lesions + no 
appeareance of new lesions as described in CR above; 
PD: PD (A >20% increase in the sum of the longest diameter of target lesions, taking as reference the 
smallest sum longest diameter recorded since the start of treatment) for target lesions irrespective of 
response of non target lesions; or PD for non target lesions irrespective of response for target lesions; or 
appearance of new non-solid or partially solid lesions or appearance of new nodules highly suspicious for 
malignancy or shown to be malignant irrespective of response of target or non target lesions; 
SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as 
reference the smallest sum longest diameter since the start of treatment. 
 
All solid nodules will be considered in a separate secondary analyses, unless they are highly suspicious 
for malignancy or are actually shown to be malignant, in which case they will represent progressive 
disease (PD). Non-suspicious (stable solid nodules with clearly benign features) will not be considered in 
the analysis according to RECIST criteria44  
Analysis of non target lesions  
Evaluation of number and size of non target lesions before and after treatment including : 
-Subsolid nodules less than 4 mm . 
-Solid nodules: evaluation of number and size of preexisting or new solid nodules will be performed. The 
analysis will be analogous to the analysis of non-solid and partially solid nodules described above, but 
substituting solid lesions for subsolid lesions. In addition, a combined analysis of nonsolid and solid 
lesions (with solid lesions considered to be non-target lesions) will be performed. 
- New nodules: A separate analysis examining new nodule appearance at 0 and 12 months  
- Cancer: the rate of cancer in each arm will be assessed. 
 
Nodule density 
We will evaluate nodule density measured by quantitative changes in mean and maximum Hounfields 
Unit (HU) before and after treatment.  
 
miRNA 
The effectiveness of the miRNA serum protocol will be evaluated by comparing the sensitivity, 
specificity and accuracy of miRNA to identify patients with GGO or with partially solid nodules and to 
predict aspirin treatment response considering the LDCT screening protocol as the reference procedure. 
The ultimate goal is to evaluate if miRNA analysis in the serum can represent a new non-invasive test to 
identify patients with GGO or with partially solid nodules and to predict treatment response to low-dose 
aspirin.  
 
Additional biomarkers 
Additional biomarkers will include the modulation of hs-CRP as marker of inflammation, the evaluation 
of urinary cotinine as marker of tobacco exposure and investigation of the potential effect of aspirin 
according to its concentration, the measurement of urinary PGEM and LTE4 normalized to urinary 
creatinine concentration. Serum TXB2 will be determined as a measure of compliance. Results will be 
compared between the two treatment arms (aspirin and placebo).

CORRELATIVE/SPECIAL STUDIES 
 
9.1 
Rationale for Methodology Selection 
 
Blood 
miRNA analysis 
miRNA extraction and purification from serum (4.5 ml of blood) will be done accordingly to standard 
procedure33. We will analyze approximately ~850 miRNAs using the TLDA qRT-PCR microfluidic cards 
(Applied Biosystems) and we will determine serum miRNA relative quantities using the ΔΔCt-method. 
Importantly, we will check the presence of hemolysis in all serum samples collected for miRNA 
screening. This will be done before the miRNA extraction by visual inspection and by measuring the 
absorbance at 414nm45, and after analysis of the expression ratios of couples of miRNAs found by us and 
by others to be sensitive enough to reveal hidden hemolysis45. In addition, we will introduce spike-in 
synthetic miRNAs to be used as standard references in every sample screened. This will allow us to 
control either the efficiency of the extraction procedure and of all the qRT-PCR reactions. 
Data analysis will be performed using R software (http://www.r-project.org/) and SAS software 
(http://www.sas.com/) for correlation analysis with all other clinical, pathological and radiological 
parameters. 
 
hs-CRP 
Serum concentrations of C-reactive protein as marker of inflammation will be measured by means of 
commercially available assays. Serum samples from the same patient obtained at different time-points 
will be run in batches in order to reduce analytical variability. Standards for good laboratory practice are 
applied. Monitoring of precision and reproducibility will be performed by processing commercially 
available control samples and internal in-house prepared pool of samples in each run. 
 
Urine 
Urine concentrations of cotinine, prostaglandin E metabolite and leukotriene E4 will be measured by 

DCP Protocol Number MDA2013-01-01 
IEO 833/13F (IEO37) Protocol version 9, version date March 13, 2017                    Protocol Version 14, Amendment 7, Dated March 13, 2017

means of commercially available assays. Urine samples from the same patient obtained at different time-
points will be run in batches in order to reduce analytical variability. Standards for good laboratory 
practice are applied. Monitoring of precision and reproducibility will be performed by processing 
commercially available control samples and internal in-house prepared pool of samples in each run.  
 
Cotinine 
We will use NicAlert® test (Nymox Pharmaceutical Corporation, Quebec, Canada) to measure tobacco 
product exposure. The test is able to detect exposed to tobacco products such as cigarettes, pipes, or 
chewing tobacco within the past 48 hours. Second hand smoke exposure may cause a positive result in a 
non-user of tobacco products.  
NicAlert® is a semi-quantitative immunochromatographic assay for urinary cotinine measurements, that 
uses monoclonal antibody-coated gold particles and a series of avidity traps that allow quantification. The 
sample collection end of the strip contains gold particles coated with monoclonal antibodies to cotinine, a 
relatively long-lived metabolite of nicotine. The distance the gold migrates on the strip is shown by a 
clear color change and provides an accurate measure of the amount of cotinine in the sample. The cutoff 
concentration for the NicAlert® test is 100 ng/mL. The NicAlert™ Negative Controls consist of cotinine-
free (NicAlert® Level "0") human preserved pathogen-free urine. The NicAlert® Positive Controls 
consists of cotinine-free urine spiked with cotinine to concentrations of 400 ng/mL cotinine (Low Positive 
Control, NicAlert® level "4") and 2000 ng/mL cotinine (High Positive Control, NicAlert® level "6"). 
 
PGEM 
Because of the rapid metabolism of prostaglandin E2 (PGE2), the determination of the in vivo biosynthesis 
is often best accomplished by the measurement of the concentration of PGE2 metabolites. We will 
measure urinary concentrations of prostaglandin E metabolites (PGEM) by a competitive enzyme 
immunoassay (EIA) kit purchased from Cayman (Cayman Chemical Co., Ann Arbor, Michigan, United 
States) that converts all major metabolites into a single stable derivative which is easily measurable by 
EIA. The assay is based on the competition between PGE2 and PGE2-acetylcholinesterase (AChE) 
conjugate (PGE2 tracer) for a limited amount of PGE2 monoclonal antibody. Because the concentration of 
the PGE2 tracer is held constant while the concentration of PGE2 varies, the amount of PGE2 tracer that is 
able to bind the PGE2 monoclonal antibody is inversely proportional to the concentration of PGE2 in the 
well. This antibody complex PGE2 binds to goat polyclonal anti-mouse IgG that has been previously 
attached to the well. The plate is washed to remove any unbound reagents and then Ellmans reagent 
(which contains the substrate to AChE) added to the well. The product of this enzymatic reaction has a 
distinct yellow color that absorbs strongly at 412 nm. The intensity of this color, determined 
spectrophotometrically, is proportional to the amount of PGE2 tracer bound to the well, which is inversely 
proportional to the amount of free PGE2. 
We will check for interference by contaminants present in urine by 1:10 and 1:30 dilution of crude 
samples with phosphate-buffered saline. If the two different dilutions of the samples show good 
correlation (differ by 20% or less) in the final calculated PGE2 concentration, purification is not required. 
If we do not see good correlation of serial dilutions, purification according to the purification protocol 
provided with the assay method will be applied. 
 
LTE4 
Urinary leukotriene E4 (uLTE4) will be determined by a competitive enzyme immnoassay kit (Cayman 
Chemical Co., Ann Arbor, Michigan, United States). The assay is based on the competition between 
uLTE4 and uLTE4-acetylcholinesterase (AChE) conjugate (uLTE4 tracer) for a limited amount of uLTE4 
Antiserum. Because the concentration of the uLTE4 tracer is held constant while the concentration of 
uLTE4 varies, the amount of uLTE4 tracer that is able to bind the uLTE4 antiserum will be inversely 
proportional to the concentration of uLTE4 in the well. This antibody uLTE4 complex binds to a mouse 
monoclonal anti-rabbit IgG that has been previously attached to the well. The plate is washed to remove 
any unbound reagents and then Ellman’s reagent (which contains the substrate to AChE) added to the

well. The product of this enzymatic reaction has a distinct yellow color that absorbs strongly at 412 nm. 
The intensity of this color, determined spectrophotometrically, is proportional to the amount of uLTE4 
tracer bound to the well, which is inversely proportional to the amount of free uLTE4.  
We will check for interference by contaminants present in urine by 1:10 and 1:30 dilution of crude 
samples with phosphate-buffered saline. If the two different dilutions of the samples show good 
correlation (differ by 20% or less) in the final calculated uLTE4 concentration, purification is not required. 
If we do not see good correlation of serial dilutions, purification according to the purification protocol 
provided with the assay method will be applied. 
 
TXB2 
Serum concentration of thromboxane B2 (TXB2) will be determined by a competitive enzyme linked 
immunosorbent assay (Neogen TM, Lexingotn, KY, USA). The assay is based on the competition 
between the enzyme conjugate and the TXB2 in the sample for a limited amount of binding sites on the 
antibody coated plate. The detection limit for the TXB2 assay is 4 pg/ml. 
 
 
BIOREPOSITORY 
DNA and RNA will be prepared and stored for future unspecified analyses for specific markers for whole 
genome DNA and RNA profiling. Samples will be stored at IEO Biobank and Biomolecular Resource 
Infrastructure (IBBRI). A specific institutional informed consent will be used. 
 
9.2 
Comparable Methods 
 
We will use established and validated assays for determination of changes in biomarkers’ expression in 
this study. We plan to evaluate biomarkers in both serum, and urine specimens for secondary endpoints 
evaluation. Specifically, for miRNA signature, we will use protocols developed and validated by our 
group33 within the Cosmos 1 screening program.  
 
For serum hs-CRP and urine biomarkers (PGEM, leukotriene and cotinine) we will utilize standard 
protocols of commercially available kits already described in peer-reviewed publications. As to hs-CRP, 
our group has already published several papers involving this biomarker37,46-48. Two different methods 
have been applied. The former was a chemiluminescent enzyme immunometric assay (Diagnostic 
Products Corp, Los Angeles CA) designed for the immulite automated analyzer. more recently a high 
sensitivity turbidimetric method for cobas integra 800 was adopted (Roche Diagnostics, Mannheim, 
Germany). The two methods showed an excellent correlation (r2=0.99).

Collection and Handling Procedures 
 
 
All blood and urine samples will be withdrawn under fasting condition (at least 6 hours) preferably 
between 8 a.m. and 10 a.m. at each time point. Instructions about specimen handling and storage will be 
provided in a dedicated Manual of Procedures. 
 
A total of 8 ml of blood will be withdrawn for safety labs (at baseline, 6 and 12 months) 
 
A total of 4.5 ml of blood will be collected for miRNA (at baseline and 12 months) with the following 
recommendation for each blood withdrawal: 
1) Patients should be fasting at least 6 hours before blood collection 
2) Information about oral therapy with anti-inflammatory, anticoagulants, steroids or other drugs will be 
collected the same day. 
3) Patients must have been free of any infection (including flu) and inflammatory diseases for a week 
prior to the collection of blood samples. 
4) Before any instrumental or physical examination has been performed 
 
Fasting (at least 6 hours) blood samples will be collected in all participants free of any infection 
(including flu) and inflammatory diseases for a week prior to the collection of blood samples at baseline 
and after 12 months of treatment. In order to avoid skin contamination, the first 3 mL of blood should not 
be used for serum preparation. Blood samples (4.5 ml) will be collected in tubes without anti-coagulant 
(white cap), left at room temperature for 30-60 minutes to clot, then spun at 3000 rpm (1000 g, Megafuge 
2.0 – Heraeus) for 10 minutes at room temperature. The serum will be immediately removed slowly by 
using a plastic transfer pipette, leaving 0.5 cm remaining to avoid disturbing the serum–clot interface, 
dispensed in 0.6 ml aliquots (for a total of 4 aliquots) into 1.5 ml cryotubes (Thermo Fisher Scientific), 
specifically labeled with a barcode, and snap frozen in dry ice. Aliquots will then be transferred in a 
dedicated -80°C freezer. 
 
A total of 7.5 ml of blood will be collected into tubes containing clot activator for hs-CRP (at baseline, 6 
and 12 months): 
Morning fasting blood samples are centrifuged at 1850xg and one ml serum  aliquots will be stored into

REPORTING ADVERSE EVENTS/ADVERSE DRUG REACTIONS 
 
DEFINITION ADVERSE EVENT (AE): AE means any untoward medical occurrence associated with 
the use of a drug in humans, whether or not considered drug related. An AE can therefore be any 
unfavorable and unintended sign, symptom, or disease temporally associated with participation in a study, 
whether or not related to that participation. This includes all deaths that occur while a participant is on a 
study. 
 
Please note that all abnormal clinical laboratory values that are determined to be of clinical significance 
based on a physician’s assessment are to be reported as AEs. Those labs determined to be of no clinical 
significance or of unknown clinical significance (per the physician’s assessment) should not be reported 
as AEs. Any lab value of unknown clinical significance should continue to be investigated/followed-up 
further for a final determination, if possible. 
 
A list of AEs that have occurred or might occur (Reported Adverse Events and Potential Risks) can be 
found in §6.2, Pharmaceutical Information, as well as the Investigator Brochure or package insert.  
 
DEFINITION ADVERSE DRUG REACTION (ADR): all untoward and unintended responses to an 
investigational medical product related to any dose administered (Directive 2011/20/EC). 
 
Comment: all AEs judged by either the reporting investigator or the sponsor as having a reasonable causal 
relationship to a medical product qualify as ADR. The expression of reasonable causal relationship means

Serious Adverse Events 
 
11.2.1 DEFINITION: According the European Directive 2001/20/EC and Fed. Reg. 75, Sept. 29, 2010 
defines SAEs as those events, occurring at any dose, which meet any of the following criteria: 
 
Results in death 
 
Is life threatening (Note: the term life-threatening refers to an event in which the patient 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). 
 
Requires inpatient hospitalization or prolongation of existing hospitalization 
 
Results in persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions 
 
Is a congenital abnormality/birth defect 
 
Important medical events that may not result in death, be life-threatening or require 
hospitalization may be considered serious when, based upon appropriate medical judgment, they may 
jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the 
outcomes listed. 
 
11.2.2 Reporting Serious Adverse Events 
The Sponsor is responsible for AE/ADR reporting to Regulatory Authority and Ethic Committee 
according to local regulation. 
The Principal Investigator will notify the Sponsor of any SAE within 24 hours of knowledge of the event.

STUDY MONITORING 
 
12.1 
Data Management 
The study PI will identify a dedicated data manager who will be responsible for the correct management 
of the trial conduct. In particular, he/she will periodically verify subject eligibility, informed consent 
signatures, accuracy and completeness of CRFs and congruency with all source documents (including 
laboratory print outs, drug inventory and distruction logs). All source documents will be collected in 
individual binders, stored in locked cupboards and accessible for any audit or inspection by authorized 
personnel. Should the PI change, custody of the records may be transferred to another competent person 
who will accept responsibility for those records. 
Written notice of such event has to be given to the local Ethics Committee at least one month in advance. 
This study will report clinical data using the Data Management Initiative (DMI) web-based application 
managed by the Consortium Biostatistics and Data Management Core. Data Management Initiative (DMI) 
infrastructure has been developed in the Division of Quantitative Sciences (DQS), MD Anderson Cancer 
Center. This infrastructure supplies integrated database and software services for web-based data 
collection, randomized treatment assignment, reporting, query, data download, and data quality 
management. The DMI will be the database of record for the protocol and subject to NCI and FDA audit. 
All DMI users will be trained to use the DMI system and will comply with the instructions in the 
protocol-specific “DMI User Manual” as well as applicable regulatory requirements such as 21 CFR; Part 
11.  Data management procedures for this protocol adheres to the Data Management Plan (DMP) contract

Participant data will be collected using protocol-specific case report forms (CRF) developed from the 
standard set of DCP Chemoprevention CRF Templates and utilizing NCI-approved Common Data 
Elements (CDEs). The approved CRFs will be used to create the electronic CRF (e-CRF) screens in the 
DMI application. Site staff will enter data into the e-CRF. Amended CRFs will be submitted to the DCP 
Protocol Information Office for review and approval.  Approved changes will be programmed into the 
DMI database by the Consortium Biostatistics and Data Management Core. 
 
12.3 
Source Documents 
 
Source documentation will include only those documents containing original forms of data, including 
clinic charts, shadow files, hospital charts, and physician notes. Data recorded directly on the CRFs 
designated as source documents (i.e., no prior written or electronic record of data) will be considered 
source data. All other data recorded on the CRFs will not be considered source documentation. 
 
12.4 
Data and Safety Monitoring Plan 
 
The Data and Safety Monitoring Plan for the MD Anderson Consortium is on file at the DCP.  This study 
will be monitored by the MDACC Data and Safety Monitoring Board, the data and safety monitoring 
board of record for this study.   The Data Safety and Monitoring Board (DSMB) reports to the President, 
or his designee, as the on-campus representative of The University of Texas Board of Regents. It oversees 
the data and patient safety issues for randomized clinical trials that originate at MD Anderson; that are 
coordinated or analyzed by MD Anderson and are not being monitored by any other DSMB; or have been 
designated as requiring DSMB monitoring at the request of the IRB, the CRC, or institution. The primary 
objectives of the DSMB are to ensure that patients' rights pertaining to participation in a research study 
are protected, and that patients' interests are prioritized over the interests of the scientific investigation. 
Responsibilities include: 
(a) Review interim analyses of outcome data (prepared by the study statistician or other 
responsible person at the time points defined in the study) approved by the IRB and 
additional time points as determined by the DSMB, and to recommend, if necessary, whether 
the study needs to be changed or terminated based on these analyses; 
(b) Determine whether, and to whom, outcome results should be released prior to the reporting of 
study results; 
(c) Review interim toxicity data and efficacy of treatment; 
(d) Review major research modifications proposed by the investigator or appropriate study 
committee prior to implementation (e.g., termination, dropping an arm based on toxicity 
results from the study or results of other studies, increasing target sample size). 
 
Refer to the Data and Safety Monitoring Plan for the MD Anderson Consortium on file at the DCP for 
further details.

STATISTICAL CONSIDERATIONS 
 
13.1 
Study Design/Description 
 
The trial will be a randomized double-blind placebo controlled phase IIb study. Patients will be 
randomized to receive either aspirin 100 mg/day or matched placebo for 1 year. Analysis will be 
performed according to intention to treat principle and then according to efficacy. 
 
The primary endpoint will be the difference of the sum of longest diameters of subsolid (non-solid or 
partially solid) lung nodules in a person-specific analysis.  
 
The sample size has been calculated assuming a -0.2 mm average reduction of the sum of the longest 
diameter of all non-solid and partially-solid lesions at 12 months with respect to baseline in the placebo 
arm vs. an expected average reduction of -1.0 mm in the aspirin group.

DCP Protocol Template Version 8.3 
–45– 
05/21/2013 
13.2 
Randomization/Stratification 
 
In order to keep at minimum the imbalance in treatments a stratified blocked randomization strategy will 
be used considering only the relevant prognostic factors. Subjects will be stratified according to screening 
vs non screening CT scan, gender, smoking habits (current versus former smokers) and nodule type (non 
solid versus partially solid nodules). A blocked randomization will be done within each stratum. 
Other possible prognostic factors are age, the number of lesions, their volume doubling time and their size 
but since there is no evidence that they affect the response probability they will be included just in a 
stratified analysis, not during the randomization process.  
 
Justification of stratification:  
Stratification by nodule type and smoking status is planned because both non solid type and active 
smoking are associated with the risk of developing lung malignancies and their natural history, while 
stratification by screening vs non screening CT scan, and gender are conservative. The effect of aspirin 
has been variable in men and women for the prevention of certain conditions49.

A sample size of 128 patients (64 per arm) achieve 80% power to detect a difference of -0.8 mm between 
the null hypothesis that both groups average reduction is –0.2 mm and the alternative hypothesis that the 
average reduction of target nodules in the aspirin group is –1.0 mm, with estimated effect size of 0.5 
(common standard deviations of 1.6 mm) and with a significance level (alpha) of 0.05 using a two-sided 
two-sample t-test. The average shrinkage in the placebo arm is derived from the Budesonide trial. 
 
13.4 
Primary Objective, Endpoint(s), Analysis Plan 
 
All randomized patients who received at least one dose will be included in the study analysis with an 
intent-to-treat approach. A secondary analysis will also be carried out after excluding non-compliers and 
subjects who will drop-out and who will refuse treatment after randomization. 
Subject will be considered compliant if at least 80% of the drug has been taken. 
Using a more conservative approach, patients who drop-out or have missing final CT scans will be 
considered in the failure group. Both the intent-to-treat and efficacy analyses will be conducted on a per 
subject basis A two-sided paired t-test will be used to compare the average change in the dimension of 
sub-solid nodules in the aspirin gorup compared to the placebo group at 1 year.  
 
13.5 
Secondary Objectives, Endpoints, Analysis Plans 
 
Generalized linear mixed models for longitudinal data will be used to compare the study groups using the 
standard general model y = X + Zu + , with y the response variable (e.g. secondary endopoint 
variable), X and  the design matrix and unknown parameters for the fixed effects and Z the design 
matrix for the random effects and u the random effects. Treatment arm (aspirin or placebo) and time visit 
(baseline, 6 and 12 months) will be considered fixed effects, smoking history and age at study entry 
random effects. Secondary endpoints include a per-lesion analysis by nodule type. Identity and logit link 
functions will be used for normal and binary data respectively All tests will be two-sided and considered 
significant at the 5% level. 
 
13.6 
Reporting and Exclusions 
 
Patients will be considered compliant with treatment if at least 80% of the drug has been taken. Non-
compliers and patients who switch the treatment assigned will be excluded from the efficacy analysis.

Patterns of observations will be classified as complete cases (no missingness), terminal (monotone) 
dropouts, intermittent (non-monotone) dropouts, mixed and no-data. A MCAR (Missing Completely At 
Random) vs. MAR (Missing At Random) statistical test will be conducted as described by Little50. 
Kendall’s b will be computed in order to test the correlation between a dichotomous indicator of missing 
observations and treatment assigned as well as any possible baseline covariates. Multiple imputation 
procedures will be adopted only for those variables whose missing data proportion will exceed the 5% 
value. 
 
13.7 
Evaluation of Toxicity 
All participants will be evaluable for toxicity from the time of their first dose of Aspirin/placebo. 
 
13.8 
Evaluation of Response 
 
All participants included in the study who have taken at least one dose of study agent will be assessed for 
response to study treatment even if there are major protocol deviations or if they are ineligible. All of the 
participants who met the eligibility criteria (with the possible exception of those who did not receive 
study agent) will be included in the main analysis. All conclusions regarding efficacy will be based on all 
eligible participants. 
No subgroup analyses are foreseen.

Informed Consent Form 
 
A RANDOMISED PHASE II TRIAL OF LOW DOSE ASPIRIN VERSUS PLACEBO IN HIGH RISK 
INDIVIDUALS WITH CT-DETECTED SUBSOLID LUNG NODULES 
 
(Testing aspirin in high risk lung cancer subjects with lung nodules) 
 
This is a clinical trial, a type of research study. Your study doctor will explain the clinical trial to you. 
Clinical trials include only people who choose to take part in it. Please take your time to make your 
decision. You may discuss your decision with your friends and family. You can also discuss it with your 
health care team. If you have any questions, you can ask your study doctor for more explanation. 
You are being asked to take part in this study because you are at increased risk for lung cancer, you are 
already participating in a screening program in this Institute and/or you have a CT (Computer 
Tomography) scan recently performed having confirmed one or more small subsolid lung nodules.  
 
What is the usual approach to my early detected lung nodules? 
 
Currently no effective drug to prevent lung cancer in people at increased risk has been discovered.  In 
your case these nodules are probably not cancerous but it is not possible to exclude that they may become 
cancers, so they should be monitored with periodic exams to evaluate their growth rate. At the moment 
the growth of your nodules does not have clinical relevance, but requires a yearly follow up with a CT 
scan. 
 
What are my other choices if I do not take part in this study?  
 
If you decide not to take part in this study, you have other choices. For example: 
you may choose to have the usual approach described above, annual CT scan 
or you may choose to do nothing. 
 
Why is this study being done? 
 
The purpose of this randomized phase II study is to compare the safety and effects of low dose aspirin 
(100 mg/day) with placebo on subjects with subsolid nodules. In this study, you will get either aspirin 
100mg/day or placebo, a pill that looks like the study drug but contains no medication. There will be 128 
subjects taking part in this study. The study will be conducted at the European Institute of Oncology in 
Milan, Italy and at the University of Texas MD Anderson Cancer Center in Houston, TX, US.  
 
What are the study groups? 
 
This study will enroll current and former asymptomatic smokers, enrolled in lung cancer annual screening 
with low dose CT or having a confirming CT scan, presenting no clinically relevant nodules. 
The study population will be divided in two study groups. Group 1 will receive the study drug, aspirin 
100 mg/day, Group 2 will receive a placebo, a pill that looks like the study drug but contains no 
medication.  
 
A computer will randomly put you in a study group—like a coin toss—to decide what group you get 
placed into. This is done because no one knows if one study group is better, the same, or worse than the 
other group. Once you are put in a group, you cannot switch to the other group. Neither you nor your 
doctor will know if you are receiving the study drug or placebo. Your doctor cannot choose which group 
you will be in.

How long will I be in this study? 
 
You will receive the study drugs for 12 months. Even if you do not finish the study, your doctor will 
continue to watch you for side effects and follow your condition for 1 month after the discontinuation of 
the study drug. 
 
What extra tests and procedures will I have if I take part in this study? 
 
At the moment the presence of pulmonary nodules requires only a yearly follow up with CT scan. 
However, there are some extra exams that you will need to have if you take part in this study (e.g., fasting 
state (at least 6 hours) for blood and urine exam, including serum pregnancy test in women of 
childbearing potential). 
 
Before you begin the study  
 
You will need to have the following extra tests and procedures to verify your eligibility (to find out if you 
can be in the study):  
Signed informed consent. 
Collection of fasting blood sample (about 30 ml) for safety routine tests and biological markers and urine 
sample for biological markers, including thromboxane B2 (TXB2), an indicator of aspirin use. 
Physical exam and record of any other medication that you are taking. 
If fully eligible you will be randomized to receive either aspirin or placebo and will be given a 7-month 
supply of aspirin or placebo. 
 
The collection of these samples (blood and urine) is required in order for you to take part in this study 
because the research on the samples is an important part of the study.  
 
Month 1 (+/- 1 week from randomization) 
 
Through a telephone call, side effects and any other medication that you are taking will be recorded. 
 
Month 3 (+/-2 weeks from randomization) 
 
Through a telephone call, side effects and any other medication that you are taking will be recorded. 
Confirmation of Month 6 clinical visit.  
 
Month 6 (+/-2 weeks from randomization) 
 
Collection of fasting blood (about 28 ml) and urine sample for safety routine tests and biological markers 
including TXB2, an indicator of aspirin use. 
Physical exam, record of any side effects and of any other medication that you are taking. 
You agree to take 
part in the study

Confirmation of Month 12 clinical visit. 
 
Month 12 (+/-2 weeks from randomization) 
 
Collection of fasting blood (about 30 ml) and urine sample for safety routine tests and biological markers 
including TXB2, an indicator of aspirin use. 
Physical exam, record of any side effects and of any other medication that you are taking. 
All the unused tablets will be returned together with the calendar. 
 
As part of the usual approach for your condition at month 12 you will have the annual CT scan . 
 
Month 13 (+/-1 week from Month 12) 
 
Through a telephone call, the side effects and the concomitant medications will be recorded. 
 
The most common risks of all these procedures are related to drawing blood from your arm: a brief pain 
and possibly a bruise.  
 
After Month 13 your participation to the aspirin study will be completed. You will continue the CT 
scan evaluation as needed. 
 
What possible risks can I expect from taking part in this study?  
 
If you choose to take part in this study, there is a risk that you may:  
Lose time at work or home and spend more time in the hospital or doctor’s office than usual. 
Be asked sensitive or private questions which you normally do not discuss. There is a risk someone could 
get access to the personal information in your medical records or other information researchers have kept 
about you. Someone might be able to trace this information back to you. The researchers believe the 
chance that someone will identify you is very small, but the risk may change in the future as people come 
up with new ways of tracing information. In some cases, this information could be used to make it harder 
for you to get or keep a job.  
There can also be a risk in finding out new genetic information about you. New health information about 
inherited traits that might affect you or your blood relatives could be found during a study. 
There is also a risk that you could have side effects.  
 
Here are important points about side effects: 
The study doctors do not know who will or will not have side effects. 
Some side effects may go away soon, some may last a long time, or some may never go away.  
Some side effects may be serious and may even result in death.  
 
Here are important points about how you and the study doctor can make side effects less of a problem: 
Tell the study doctor if you notice or feel anything different so they can see if you are having a side effect. 
The study doctor may be able to treat some side effects. 
The study doctor may adjust the study drugs to try to reduce side effects.

Females must be postmenopausal (i.e, at least 1 year passed after the last menstruation), surgically sterile, 
or using acceptable birth control measures as judged by the Investigator. (A fertile woman is defined as 
being of child-bearing potential, from first menstruation to 1 year after last menstruation). Negative serum 
beta-HCG for women of childbearing potential will be required at baseline and during study. It is 
important you understand that you need to use birth control while on this study. Check with your study 
doctor about what kind of birth control methods to use and how long to use them. Some methods might 
not be approved for use in this study. For more information about risks and side effects, ask your study 
doctor. 
 
What possible benefits can I expect from taking part in this study? 
 
This study may or may not help you because we do not know how the study drug will compare to the 
usual approach for your condition. This study may help us to learn things that could help people in the 
future. You have 50% chance to take Aspirin. Aspirin may be protective against lung cancer. 
 
Can I stop taking part in this study? 
 
Yes. You can decide to stop at any time. If you decide to stop for any reason, it is important to let the

Who will see my medical information?  
 
Your privacy is very important to us and we will make every effort to protect it. Your information may be 
given out if required by law. However, we will do our best to make sure that any information that is 
released will not be able to identify you. Some of your health information, and/or information about your 
specimen, from this study will be kept in a central database for research. Your name or contact 
information will not be put in the database. 
There are organizations that may inspect your records. These organizations are required to make sure your 
information is kept private. Some of these organizations are: 
The study sponsor and any drug company supporting the study  
The Institutional Review Board, IRB, is a group of people who review the research with the goal of 
protecting the people who take part in the study.

get health benefits from any of these studies. The researchers leading this optional study hope the results 
will help other people with cancer in the future. 
 
The results will not be added to your medical records, and you or your study doctor may not know the 
results. 
 
You will not be billed for these optional studies.  
 
You can still take part in the main study even if you say ‘no’ to any or all of these studies. If you sign up 
for but cannot complete any of the studies for any reason, you can still take part in the main study. 
 
 
Optional Sample Collections for Biobanking for Possible Future Studies  
 
Researchers are trying to learn more about cancer, and other health problems. Some of this research is 
done using samples from your blood and urine. Through these studies, researchers hope to find new ways 
to prevent, detect, treat, or cure health problems.  
 
Some of these studies may be about genes. Genes carry information about features that are found in you 
and in people who are related to you. Researchers are interested in the way that genes affect how your 
body responds to treatment.  
 
If you choose to take part, a sample of blood and urine will be collected on the scheduled day of the main 
study. The researchers ask your permission to store and use your samples and health information for 
medical research. Both DNA and RNA will be prepared and stored for future unspecified analyses for 
markers of whole genome RNA and DNA profiling. The research that may be done is unknown at this 
time. 
Storing samples for future studies is called “biobanking” The Biobank is being run by Istituto Europeo di 
Oncologia (IBBRI) and the section regarding this study is supported by the National Cancer Institute. 
If you need information about the biological samples or results obtained from the research, you can 
contact the coordinator of IBBRI, Dr Giuseppina Bonizzi (email Giuseppina.bonizzi@ieo.it or phone: 
+390294375155) 
 
What is involved? 
If you agree to take part, here is what will happen next: 
Your sample and some related information may be stored in the Biobank, along with samples and 
information from other people who take part. The samples will be kept until they are used up. 
Qualified researchers can submit a request to use the materials stored in the Biobank. A research 
committee at the clinical trials organization, and/or the National Cancer Institute, will review each 
request. There will also be an ethics review to ensure that the request is necessary and proper. Researchers 
will not be given your name or any other information that could directly identify you.  
Neither you nor your study doctor will be notified if/when research is conducted using your samples.  
Some of your genetic and health information may be placed in central databases that may be public, along 
with information from many other people. Information that could directly identify you will not be 
included.  
 
What are the possible risks? 
 
The most common risks related to drawing blood from your arm are brief pain and possibly a bruise.  
 There is a risk that someone could get access to the personal information in your medical records or other 

DCP Protocol Number MDA2013-01-01

DCP Protocol Template Version 8.3 
–59– 
05/21/2013 
information we have stored about you. 
There is a risk that someone could trace the information in a central database back to you. Even without 
your name or other identifiers, your genetic information is unique to you. The researchers believe the 
chance that someone will identify you is very small, but the risk may change in the future as people come 
up with new ways of tracing information.  
 
4) There are laws against the misuse of genetic information, but they may not give full protection. New 
health information about inherited traits that might affect you or your blood relatives could be found 
during a study. The researchers believe the chance these things will happen is very small, but cannot 
promise that they will not occur.  
 
For US site(s) only 
A new Federal law, called the Genetic Information Nondiscrimination Act (GINA), generally makes it 
illegal for health insurance companies, group health plans, and most employers to discriminate against 
you based on your genetic information. This law generally will protect you in the following ways  
Health insurance companies and group health plans may not request your genetic information that we get 
from this research.  
 
Health insurance companies and group health plans may not use your genetic information when making 
decisions regarding your eligibility or premiums.         
 
Employers with 15 or more employees may not use your genetic information that we get from this 
research when making a decision to hire, promote, or fire you or when setting the terms of your 
employment. All health insurance companies and group health plans must follow this law by May 21, 
2010. All employers with 15 or more employees must follow this law as of November 21, 2009. 
 
Be aware that this new Federal law does not protect you against genetic discrimination by companies that 
sell life insurance, disability insurance, or long-term care insurance.  
 
 
 
 
How will information about me be kept private?  
Your privacy is very important to the researchers and they will make every effort to protect it. Here are 
just a few of the steps they will take: 
When your sample(s) is sent to the researchers, no information identifying you (such as your name or 
social security number) will be sent. Samples will be identified by a unique study code only. The list that 
links the unique code to your name will be kept separate from your sample and health information. Any 
Biobank and related staff with access to the list must sign an agreement to keep your identity confidential. 
Researchers to whom Istituto Europeo di Oncologia sends your sample and information will not know 
who you are. They must also sign an agreement that they will not try to find out who you are. 
Information that identifies you will not be given to anyone, unless required by law. 
If research results are published, your name and other personal information will not be used. 
 
What are the possible benefits?  
You will not benefit from taking part but the researchers, using the samples from you and others, might 
make discoveries that could help people in the future. 
 
Are there any costs or payments?  
There are no costs to you or your insurance. You will not be paid for taking part. If any of the research 
leads to new tests, drugs, or other commercial products, you will not share in any profits.
