RATIONALE 
Myocardial injury has been described in up to 30% of COVID-19 infected 
patients, and portends a poor prognosis with currently no known treatment. 
Colchicine is a widely available, well-established, inexpensive, oral anti-
inflammatory agent that has been FDA approved for the treatment of 
inflammatory disorders including gout and familial Mediterranean Fever. 
Trials have also shown its benefit to prevent post-cardiotomy syndrome, to 
treat acute and recurrent pericarditis, and reduce cardiovascular events after 
myocardial infarction. We extrapolate based on these indications and studies 
that colchicine may also help improve outcomes in hospitalized COVID-19 
patients with evidence of cardiac injury.  
 
 
STUDY DESIGN 
Open-label (unblinded) randomization to treatment of colchicine plus 
current care per institution treating physicians vs. current care per institution 
treating physicians (control arm) 
 
 
PRIMARY OBJECTIVE 
To determine if Colchicine improves short-term outcomes in 
hospitalized COVID-19 patients with cardiac manifestations of 
disease. 
 
 
SECONDARY 
OBJECTIVES 
To assess if Colchicine reduces additional indices of cardiac injury in 
hospitalized COVID-19 patients with cardiac manifestations of disease

SAFETY 
EVALUATIONS 
Reporting to regulatory bodies (MCVIIRB, FDA) will only be required for 
serious adverse events judged by the treating physician and study 
investigators to be potentially related to the administration of the study drug. 
All other adverse events will be reviewed by the study investigators and 
reported per FDA and IRB regulations.  
PLANNED INTERIM 
ANALYSES  
When approximately 25% of patients have completed the study, an interim 
analysis for safety will be conducted by the study investigators. Serious 
adverse events will be monitored by the study committee on an ongoing 
basis throughout the study. Serious adverse events will be reported to the 
Baptist Health South Florida (BHSF) IRB and FDA.  
Statistical Analysis Plan 
Appropriate data analysis sets will be defined. The intent-to-treat (ITT) 
analysis set will be used in the analyses of the primary and secondary 
endpoints. The ITT analysis set will include data from all subjects who are 
randomized, with study drug assignment designated to initial randomization, 
regardless of whether subjects receive any study drug or receive a different 
regimen from that to which they were randomized. A safety analysis set will 
comprise data from subjects who receive at least one dose of study drug, 
with treatment regimen assignment (Colchicine or control) designated 

Colchicine for the Treatment of Cardiac Injury in COVID-19

according to the actual regimen received. Per-Protocol (PP) analysis set will 
be used for sensitivity analysis for the primary and secondary endpoints. 
 
The primary endpoint is the composite event rate of all-cause mortality, 
need for mechanical ventilation, or need for MCS at 90 days. Fisher’s exact 
test will be used to compare the proportion of patients achieve the composite 
event between two study arms. For each arm, the proportion of patients 
achieve the composite event at 90 days will be calculated, along with the 
95% exact confidence interval. 
 
For the secondary endpoints: 
1) Time (days) to the primary end point: Kaplan Meier estimates will be 
provided for each study arm and presented graphically. Log-rank test will be 
used to compare the event curves between study arms. Hazard ratios and 
corresponding 95% CIs will be presented. 
2) Individual components of the primary endpoint, and 90-day re-
hospitalization:  
For each of these, Fisher’s exact test will be used to compare the event rate 
between two study arms. For each arm, the proportion of patients achieve 
the composite event at 90 days will be calculated, along with the 95% exact 
confidence interval. 
3) Peak troponin level, Delta (change from baseline to peak) troponin level, 
Baseline BNP level, Inflammatory biomarkers (baseline and delta CRP and 
D-Dimer), Hospital length of stay: For each of these, unpaired t test or 
Wilcoxon rank rum test will be used to compare the two study arms. For 
each arm, descriptive statistics such as mean, median, standard deviation, 
IQR will be summarized and reported. 
 
Safety Analysis: Safety profile including AE and SAEs will be reported. 
Simple descriptive statistics will be used to summarize toxicities in terms of 
type, severity and minimum or maximum values for laboratory measures, 
time of onset, duration, and reversibility or outcome. Tables will be created 
to summarize these toxicities and side effects. Safety Analyses will be 
performed on Safety Analysis Set. 
Rationale for Number of 
Subjects 
This is an open-label, randomized controlled study with the primary 
objective to determine if Colchicine improves short-term outcomes in 
hospitalized COVID-19 patients with cardiac manifestations of disease. 
Patients will be randomized in 1:1 ratio to receive colchicine 0.6 mg po BID 
x 30 days plus current care per treating physicians versus current care per 
physicians alone (control arm). The primary endpoint is the composite event 
rate of all-cause mortality, need for mechanical ventilation, or need for MCS 
at 90 days. Sixty-eight patients per arm are needed to achieve 80% power to 
detect 20% difference in this composite event rate between the two groups, 
assuming 10% in the treatment group and 30% event rate in the control 
group, with a two-sided Fisher’s exact test at a 0.05 significance level.

1 BACKGROUND 
SARS-CoV-2, a novel betacoronavirus that causes a new human disease referred to as COVID-
19, has led to a worldwide pandemic affecting over a million people to date. Of those patients 
infected, up to 80% have only mild symptoms that resolve spontaneously.1 Patients that develop 
more severe symptoms are generally hospitalized and can experience acute respiratory distress, 
cardiac injury or shock, renal failure, and ultimately death.2 Patients with underlying 
cardiovascular disease and elevated cardiac biomarkers are at increased risk with mortality 
reaching up to 70%.3,4 While several mechanisms have been postulated for how SARS-CoV-2 
may damage the heart, it is plausible that the indirect damage from innate, cellular, or humoral 
immune response including ‘cytokine storm’ may play a pivotal role.5 We hypothesize that 
Colchicine may attenuate the cardiac injury observed in later stages of COVID-19 through 
downregulation of the inflammatory and the host adaptive immune response.  
1.1 
Overview of Non-Clinical Studies 
Colchicine is a microtubule inhibitor and anti-inflammatory agent.6 It has been suggested that the 
inhibition of the microtubule polymerization interferes with lipopolysaccharides resulting in the down-
regulation of interleukin (IL) - 6, IL-1, GM-CSF, and the NLRP3 inflammasome.7 Study of the COVID-
19 inflammatory cascade shows CD4+T lymphocytes rapidly activated to pathogenic T helper (Th1) cells 
that generate granulocyte-macrophage colony-stimulating factor (GM-CSF), as well as cytokines that 
induces inflammatory CD14+ and CD16+ monocytes with high expression of IL-6.8 Clinically, there is a 
marked increase in C-reactive protein (CRP), aspartate transaminases (AST), alanine transaminases 
(ALT), and decreased lymphocytes, reflecting the pro-inflammatory state.9 Plasma troponin levels have 
been shown to be associated with a significant increase in CRP levels, which is associated with increased 
cardiac injury and mortality.10   
 
1.2 
Overview of Clinical Studies 
Colchicine has been FDA approved for gout and familial Mediterranean fever.7 Several studies have 
shown benefit in acute and recurrent pericarditis and post-cardiotomy, and more recently post-myocardial 
infarction.11-15 Microtubule inhibition may also interfere with the viral replication machinery by 
disrupting the cellular cytoskeleton, and colchicine in viral myocarditis has been shown to improve left 
ventricular ejection fraction after treatment.16,17 We extrapolate from these studies, that colchicine may 
benefit hospitalized COVID-19 patients with evidence of cardiac injury.  
2 STUDY RATIONALE 
Cardiac injury has been described in up to 30% of COVID-19 infected patients, and portends a poor 
prognosis with currently no known treatment. Colchicine is a widely available, well-established, 
inexpensive, oral anti-inflammatory agent that may help reduce myocardial injury in hospitalized patients 
with COVID-19.

2.1 
Risk / Benefit Assessment 
The most common adverse event with colchicine is gastrointestinal intolerance (diarrhea, emesis, nausea, 
abdominal discomfort) leading to discontinuation in 5-8% of patients. Myelosuppression and aplastic 
anemia are rare at the proposed dosages. Neuromuscular toxicity has been documented at an increased 
risk with drugs inhibitor P-glycoprotein. Taking into account there is no known treatment to prevent or 
treat myocardial injury in COVID-19 patients, we feel the benefits of the medication outweigh its 
relatively small risks.  
3 STUDY OBJECTIVES 
3.1 
Primary Objective 
The primary objective is to assess if Colchicine improves short-term outcomes in hospitalized COVID-19 
patients with cardiac manifestations of disease. The primary endpoint is the composite of all-cause 
mortality, need for mechanical ventilation, or need for MCS at 90 days. 
3.2 
Secondary Objectives 
• 
To assess whether or not Colchicine reduces additional indices of cardiac injury in 
hospitalized COVID-19 patients with cardiac manifestations of disease

STUDY DESIGN 
4.1 
Study Overview 
We propose a single center, open-label (unblinded) randomized controlled trial. Patients will be 
randomized in a 1:1 ratio to receive Colchicine 0.6 mg po BID x 30 days plus current care per treating 
physicians versus current care per treating physicians alone (control arm). Importantly, this trial design 
allows for patients in either study arm to receive other investigational drugs for COVID-19 as new 
science emerges. The primary endpoint is the composite of all-cause mortality, need for mechanical 
ventilation, or need for MCS at 90 days. Secondary endpoints include time (days) to the primary end 
point, the individual components of the primary endpoint, other markers of cardiac injury (peak and delta 
troponin and baseline BNP), inflammatory biomarkers (baseline and delta CRP and D-Dimer levels), and 
90-day re-hospitalization. The treatment duration will be 30 days with a 90-day follow-up period. 
Inclusions/exclusion criteria will be reviewed to determine patient eligibility.   
The method of permuted block randomization will be used. Permuted block sizes are not disclosed to the 
study personnel to minimize the likelihood of their being able to predict the next randomization 
assignment in the series. Eligible participants will be assigned in 1:1 ratio to an unblinded fashion to one 
of the following dosing regimens: 
● Colchicine at 0.6 mg po bid for 30 days 
● Dose reductions in the setting of concomitant CYP3A4 and P-glycoprotein inhibitors, 
in the setting of severe renal and hepatic disease, or if GI symptoms occur. Total 
duration of subject participation will be 30 days treatment followed by a 90 days 
follow-up period.  Total duration of the study is expected to be 12 months.

5 CRITERIA FOR EVALUATION 
5.1 
Primary Efficacy Endpoint 
The primary endpoint is the composite of all-cause mortality, need for mechanical ventilation, or need for 
MCS at 90 days.   
5.2 
Secondary Efficacy Endpoints 
Secondary endpoints include: time (days) to the primary end point, the individual components of the 
primary endpoint, re-hospitalization rates at 90 days, markers of cardiac injury (peak troponin, delta 
troponin, baseline BNP levels, inflammatory biomarkers (baseline and delta CRP and D-Dimer levels).  
5.3 
Safety Evaluations 
Several adverse events are known with colchicine and will be monitored and include: 
• 
Blood dyscrasia such as myelosuppression, leukopenia, granulocytopenia, thrombocytopenia, 
pancytopenia and aplastic anemia have been reported with colchicine and will be monitored 
• 
Colchicine-induced neuromuscular toxicity and rhabdomyolysis have been  reported with chronic 
treatment in therapeutic doses. Patients with renal dysfunction and elderly patients are at increased 
risk, and will be monitored more closely. 
• 
The most common adverse reactions reported in clinical trials with colchicine were gastrointestinal 
trace adverse effects, occurring in up to 5-8% of patients given therapeutic doses. Typical 
symptoms include cramping, nausea, diarrhea, abdominal pain, and emesis. These events will 
warrant dose-reduction and close monitoring.

Version #: 2.0 
Version Date: 09/14/2020 
Page 17 of 35 
 
 
0.6 mg po BID x 30 days plus current care per treating physicians versus current care per physicians 
alone (control arm).  
8.2 
Blinding 
Study subjects are randomly assigned to colchicine plus current care per physicians versus current care 
per physicians (control arm).  Neither the patient nor the treatment team or study investigators will be 
blinded. This trial design allows colchicine to be added to other investigational drugs for COVID-19 as 
new data and studies are available. 
8.3 
Formulation of Test  
Colchicine is an alkaloid chemically described as (S)N- (5,6,7,9-tetrahydro- 1,2,3, 10-tetramethoxy-9-
oxobenzo [alpha] heptalen-7-yl) acetamide with a molecular formula of C22H25NO6 and a molecular 
weight of 399.4. The structural formula of colchicine is given below.  
Colchicine occurs as a pale yellow powder that is soluble in water.  
COLCRYS (colchicine, USP) tablets are supplied for oral administration as purple, film- coated, capsule-
shaped tablets (0.1575” × 0.3030”), debossed with “AR 374” on one side and scored on the other, 
containing 0.6 mg of the active ingredient colchicine USP. Inactive ingredients: carnauba wax, FD&C 
blue #2, FD&C red #40, hypromellose, lactose monohydrate, magnesium stearate, microcrystalline 
cellulose, polydextrose, polyethylene glycol, pregelatinized starch, sodium starch glycolate, titanium 
dioxide and triacetin.  
8.3.1 Packaging and Labeling 
Colchicine used for investigational purposes in COVID-19 patients will be labeled clearly and 
administered separately from normal medications. On discharge, a bottle clearly labeling the medication 
as investigational will be dispensed to the patient.  
8.4 
Supply of Study Drug at the Site 
Colchicine will be stored per manufacturer guidelines, dispensed, and accounted for by the 
Baptist Hospital investigational pharmacy.  
8.4.1 Dosage/Dosage Regimen 
Colchicine will be administered at 0.6 mg po every 12 hours. Patients under the age of 18, pregnant 
breastfeeding, or women of childbearing age who are unable to take 2 forms of contraception will be 
excluded from the study. All dosage adjustments below per manufacturer recommendations: 
1. Renal impairment: 
a. Colchicine is excreted in the urine in healthy subjects, and clearance is decreased in 
patients with impaired renal function.  
b. For patient with CrCL ≤ 30, the dose will be adjusted to 0.3 mg daily 
c. In patients with end-stage renal disease or undergoing dialysis the dose will be reduced to 
0.6 mg every 14 days

Page 18 of 35 
 
 
2. Hepatic impairment 
a. The clearance of colchicine may be significantly reduced and plasma half-life prolonged 
in patient’s hepatic impairment 
b. Dose will be adjusted to 0.3 mg daily for severe hepatic dysfunction (AST/ALT ≥ 3x 
baseline).  
3. Dose adjustments for concomitant medications 
a. Strong CYP3A4 inhibitors (Atazanavir, indinavir, itraconazole, ketoconazole, nefazodone, 
nelfinavir, ritonavir, saquinavir, telithromycin 
i.

fosamprenavir, grapefruit juice, verapamil) 
i. 
Dose reduction to 0.6 mg once daily 
c. P-glycoprotein inhibitors (Cyclosporin, ranolazine) 
i. 
Dose reduction to 0.3 mg once daily 
d. Protease inhibitors (atazanavir sulfate, darunavir) 
i. 
Dose reduction to 0.3 mg once daily 
ii. 
Colchicine should not be dispensed concomitantly with protease inhibitor in the setting of 
renal or hepatic impairment 
e. Strong CYP3A4 inhibitor and P-Glycoprotein inhibitor 
i. 
Colchicine should not be administered in the setting of both a CYP3A4 and P-
Glycoprotein inhibitor such as Clarithromycin 
 
Colchicine interacts with the P-glycoprotein transporter, and the CYP3A4 enzyme involved in drug and 
toxin metabolism. Fatal drug interactions have occurred when colchicine was taken with other drugs that 
inhibit P-glycoprotein and CYP3A4.    
Avoid taking macrolide antibiotics (erythromycin or clarithromycin), ketoconazole or cyclosporine,    
Avoid taking atazanavir, darunavir, fosamprenavir, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir, 
grapefruit juice and atorvastatin/rosuvastatin.  
8.4.2 Dispensing 
Colchicine will be dispensed by the Baptist Hospital investigational pharmacy.  
8.4.3 Administration Instructions  
Colchicine will be prepared per the Baptist Hospital investigational pharmacy protocol. The medication 
will be dispensed by the investigational pharmacy as single doses to study participants while admitted. 
The medication will be dispensed by the Baptist Hospital Pharmacy as a completed study course-supply 
and will be taken as a single doses by study participatns while admitted.  On discharge, the study drug 
will be dispensed with clear instructions to complete a 30-day course. Colchicine will be prepared per 
the Baptist Hospital investigational pharmacy protocol. On discharge, the study drug will be 
dispensed with clear instructions to complete a 30-day course.

pouch and protected from light) at room temperature according to the instructions outlined on the Drug 
Administration Instructions. 
8.6 
Study Drug Accountability 
An accurate and current accounting of the dispensing and return of study drug for each subject will be 
maintained on an ongoing basis by a member of the study site staff.  The number of study drug dispensed 
and returned by the subject will be recorded on the Investigational Drug Accountability Record.  The 
study monitor will verify these documents throughout the course of the study. 
8.7 
Measures of Treatment Compliance 
Subjects will be asked to keep a patient diary noting the day and date they take their study drug and any 
symptoms or adverse events. If the patient misses a dose, he/she will be instructed to document the event, 
but continue treatment with the next scheduled dose. Subjects will be instructed to not make up the dose.

11 ADVERSE EXPERIENCE REPORTING AND DOCUMENTATION 
11.1 
Adverse Events 
An adverse event (AE) is any untoward medical occurrence in a clinical investigation of a patient 
administered a pharmaceutical product and that does not necessarily have a causal relationship with the 
treatment.  An AE is therefore any unfavorable and unintended sign (including an abnormal laboratory 
finding), symptom or disease temporally associated with the administration of an investigational product, 
whether or not related to that investigational product.  An unexpected AE is one of a type not identified in 
nature, severity, or frequency in the current Investigator’s Brochure or of greater severity or frequency 
than expected based on the information in the Investigator’s Brochure. 
The Investigator will probe, via discussion with the subject, for the occurrence of AEs during each subject 
visit and record the information in the site’s source documents.  Adverse events will be recorded in the 
patient CRF.  Adverse events will be described by duration (start and stop dates and times), severity, 
outcome, treatment and relation to study drug, or if unrelated, the cause. 
AE Severity 
The National Cancer Institute’s Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0 
should be used to assess and grade AE severity, including laboratory abnormalities judged to be clinically 
significant. The modified criteria can be found in the study manual.  If the experience is not covered in 

Colchicine for the Treatment of Cardiac Injury in COVID-19 
Confidential 
 
Version #: 2.0 
Version Date: 09/14/2020 
Page 22 of 35 
 
 
the modified criteria, the guidelines shown in Table 1 below should be used to grade severity.  It should 
be pointed out that the term “severe” is a measure of intensity and that a severe AE is not necessarily 
serious. 
Table 1.  AE Severity Grading 
Severity (Toxicity Grade) 
Description 
Mild (1) 
Transient or mild discomfort; no limitation in activity; no medical 
intervention or therapy required. The subject may be aware of the sign 
or symptom but tolerates it reasonably well. 
Moderate (2) 
Mild to moderate limitation in activity, no or minimal medical 
intervention/therapy required. 
Severe (3) 
Marked limitation in activity, medical intervention/therapy required, 
hospitalizations possible. 
Life-threatening (4) 
The subject is at risk of death due to the adverse experience as it 
occurred. This does not refer to an experience that hypothetically 
might have caused death if it were more severe. 
 
AE Relationship to Study Drug 
The relationship of an AE to the study drug should be assessed using the following the guidelines in 
Table 2. 
Table 2.  AE Relationship to Study Drug 
Relationship 
to Drug 
Comment 
Definitely 
Previously known toxicity of agent; or an event that follows a reasonable temporal 
sequence from administration of the drug; that follows a known or expected response 
pattern to the suspected drug; that is confirmed by stopping or reducing the dosage 
of the drug; and that is not explained by any other reasonable hypothesis. 
Probably 
An event that follows a reasonable temporal sequence from administration of the 
drug; that follows a known or expected response pattern to the suspected drug; that is 
confirmed by stopping or reducing the dosage of the drug; and that is unlikely to be 
explained by the known characteristics of the subject’s clinical state or by other 
interventions. 
Possibly 
An event that follows a reasonable temporal sequence from administration of the 
drug; that follows a known or expected response pattern to that suspected drug; but 
that could readily have been produced by a number of other factors. 
Unrelated 
An event that can be determined with certainty to have no relationship to the study 
drug. 
11.2 
Serious Adverse Experiences (SAE) 
An SAE is defined as any AE occurring at any dose that results in any of the following outcomes: 
● death 
● a life-threatening adverse experience 
● inpatient hospitalization or prolongation of existing hospitalization 

Colchicine for the Treatment of Cardiac Injury in COVID-19

Version #: 2.0 
Version Date: 09/14/2020 
Page 23 of 35 
 
 
● a persistent or significant disability/incapacity 
● a congenital anomaly/birth defect  
Other important medical events may also be considered an SAE when, based on appropriate medical 
judgment, they jeopardize the subject or require intervention to prevent one of the outcomes listed.  
 
11.2.1 Serious Adverse Experience Reporting 
All SAEs that occur (whether or not related to study drug) will be reported per Baptist Health South 
Florida IRB guidelines and policy.   The collection period for all SAEs will begin after informed consent 
is obtained and end after procedures for the final study visit have been completed. 
In accordance with the standard operating procedures and policies of the local Institutional Review Board 
(IRB)/), the site investigator will report SAEs to the IRB and FDA.

12 DISCONTINUATION AND REPLACEMENT OF SUBJECTS 
12.1 
Early Discontinuation of Study Drug  
A subject may be discontinued from study treatment at any time if the subject, the sponsor/investigator, or 
study team determines that it is not in the subject’s best interest to continue.  The following is a list of 
possible reasons for study treatment discontinuation:  
● Subject withdrawal of consent (or assent) 
● Subject is not adherent with study procedures 
● Adverse event that in the opinion of the investigator would be in the best interest of the 
subject to discontinue study treatment 
● Protocol violation requiring discontinuation of study treatment 
● Loss to follow-up 
● Sponsor request for early termination of study 
● Positive pregnancy test or women of childbearing age who can no longer take adequate 
contraception, which includes: 
● Intrauterine devices (IUD), contraceptive implants, or tubal sterilization 
● Hormone method with a barrier method 
● Two barrier methods 

Colchicine for the Treatment of Cardiac Injury in COVID-19

Version #: 2.0 
Version Date: 09/14/2020 
Page 24 of 35 
 
 
● If a partner’s vasectomy is the chosen method of contraception, a hormone or 
 
barrier method must also be used in conjunction  
If a subject is withdrawn from treatment due to an adverse event, the subject will be followed and treated 
by the Investigator until the abnormal parameter or symptom has resolved or stabilized.   
All subjects are free to withdraw from participation at any time, for any reason, specified or unspecified, 
and without prejudice. 
Reasonable attempts will be made by the investigator to provide a reason for subject withdrawals.  The 
reason for the subject’s withdrawal from the study will be recorded in the study. 
12.3 
Withdrawal of Subjects from the Study 
A subject may be withdrawn from the study at any time if the subject, the sponsor/investigator, or the 
study team determines that it is not in the subject’s best interest to continue.   
All subjects are free to withdraw from participation at any time, for any reason, specified or unspecified, 
and without prejudice. 
Reasonable attempts will be made by the investigator to provide a reason for subject withdrawals.  The 
reason for the subject’s withdrawal from the study will be specified in the subject’s source 
documents.  As noted above, subjects who discontinue study treatment early (i.e., they withdraw prior to 
the 30-day visit) should have an early discontinuation visit if they have been discharged from the hospital. 
Refer to Section 10 for early termination procedures.  Subjects who withdraw after discharge from the 
hospital but prior to day 30 should be encouraged to come in for a final laboratory and imaging visit. 
12.4 
Replacement of Subjects 
Subjects who withdraw from the study treatment will not be replaced.   
Subjects who withdraw from the study itself will not be replaced.   
 
13 PROTOCOL VIOLATIONS 
A protocol violation occurs when the subject, investigator, or Sponsor fails to adhere to significant 
protocol requirements affecting the inclusion, exclusion, subject safety and primary endpoint criteria.  
Protocol violations for this study include, but are not limited to, the following: 
● Failure to meet inclusion/exclusion criteria 
● Use of a prohibited concomitant medication 
Failure to comply with Good Clinical Practice (GCP) guidelines will also result in a protocol violation. 
The Investigator will determine if a protocol violation will result in withdrawal of a subject. 
When a protocol violation occurs, it will be discussed with the investigator and a Protocol Violation Form 
detailing the violation will be generated. This form will be signed by the Investigator. tThe form will be 
sent to the BHSF IRB and a copy will be  filed in the site’s regulatory binder.

14 STATISTICAL METHODS AND CONSIDERATIONS 
14.1 
General Considerations 
Data collected in this study will be presented using summary tables and patient data listings. Continuous 
variables will be summarized using descriptive statistics, specifically the mean, median, standard 
deviation, minimum, and maximum. Categorical variables will be summarized by frequencies and 
percentages. \Data Sets Analyzed 
• Intent-to-Treat (ITT) Analysis Set 
The ITT analysis set includes all subjects who are randomized regardless of whether subjects 
receive any study drug(s), or receive a different regimen from the regimen they were randomized 
to. Treatment assignment will be designated according to randomization. This analysis set will 
be used in the analysis for the primary endpoint and the secondary endpoint. 
 
• Per-Protocol (PP) Analysis Set 
The PP analysis set includes data from subjects in the ITT analysis set who meet the general 
criteria defining the target population for this study, are adherent to the protocol, are compliant 
with study drug treatment, and are evaluable for relevant efficacy endpoints. Treatment 
assignment will be designated according to the actual treatment received. The PP analysis set 
will be used in sensitivity analyses of the primary and secondary endpoints. 
 
• Safety Analysis Set 
A safety analysis set will include data from subjects who receive at least one dose of study 
treatment, with treatment assignments designated according to the actual treatment received. 
This analysis set will be used in the analyses of safety variables as well as study treatment 
administration. 
14.2 
Demographic and Baseline Characteristics 
The following demographic variables at screening will be included: race, sex, age, BMI, medication 
history, co-morbidities including cardiovascular disease and risk factors for cardiovascular disease.   
14.3 
Analysis of Primary Endpoint 
The primary endpoint is the composite event rate of all-cause mortality, need for mechanical ventilation, 
or need for MCS at 90 days. Fisher’s exact test will be used to compare the proportion of patients achieve 
the composite event between two study arms. For each arm, the proportion of patients achieve the 
composite event at 90 days will be calculated, along with the 95% exact confidence interval. 
14.4 
Analysis of Secondary Endpoints 
Secondary endpoint: Time (days) to the primary end point Kaplan Meier estimates will be provided 
for each study arm and presented graphically. Log-rank test will be used to compare the event curves

Version #: 2.0 
Version Date: 09/14/2020 
Page 26 of 35 
 
 
between study arms. Hazard ratios and corresponding 95% CIs (as calculated using a Cox proportional 
hazards regression model) will be presented. 
• Secondary endpoints: Individual components of the primary endpoint. For each of these, 
Fisher’s exact test will be used to compare the event rate between two study arms. For 
each arm, the proportion of patients achieve the composite event at 90 days will be 
calculated, along with the 95% exact confidence interval. 
• 
Secondary endpoints: Peak troponin level, Delta (change from baseline to peak) troponin level, 
baseline BNP level, Inflammatory biomarkers (baseline and delta CRP and D-Dimer), Hospital 
length of stay 
• 
For each of these, unpaired t test or Wilcoxon rank rum test will be used to compare the two study 
arms. For each arm, descriptive statistics such as mean, median, standard deviation, IQR will be 
summarized and reported. 
14.5 Analysis of Safety 
Safety profile including AE and SAEs will be reported. Simple descriptive statistics will be used 
to summarize toxicities in terms of type, severity and minimum or maximum values for 
laboratory measures, time of onset, duration, and reversibility or outcome. Tables will be created 
to summarize these toxicities and side effects. Safety Analyses will be performed on Safety 
Analysis Set. 
14.6 Sample Size Justification 
This is an open-label, randomized controlled study with the primary objective to determine if Colchicine 
improves short-term outcomes in hospitalized COVID-19 patients with cardiac manifestations of disease. 
Patients will be randomized in 1:1 ratio to receive colchicine 0.6 mg po BID x 30 days plus current care 
per treating physicians versus current care per physicians alone (control arm). The primary endpoint is the 
composite event rate of all-cause mortality, need for mechanical ventilation, or need for mechanical 
circulatory support (MCS) at 90 days. 68 patients per arm are needed to achieve 80% power to detect 
20% difference in this composite event rate between the two groups, assuming 10% in the treatment 
group and 30% event rate in the control group (based on recent published studies18,19,20), with a two-sided 
Fisher’s exact test at a 0.05 significance level. Accounting for 9% attrition rate, a total of 150 subjects 
(n=75 per arm) will be enrolled. 
As our site will be enrolling about 75 patients in the trial, we are aiming to achieve the calculated 
statistical sample size by sharing our de-identified data results with the UCLA (University of California 
Los Angeles) Medical Center in California, conducting this same trial in the Los Angeles area with this 
same identical clinical study protocol. Our IND submission does cross-reference the UCLA IND already 
approved by the FDA.

Study personnel will enter data from source documents corresponding to each subject into the protocol-
specific electronic Case Report Form (eCRF) OR paper CRF when the information corresponding to that 
visit is available.  Subjects will not be identified by name in the study database or on any study 
documents to be collected by the Sponsor (or designee), but will be identified by a subject number. 
The Investigator is responsible for all information collected on subjects enrolled in this study.  All data 
collected during the course of this study must be reviewed and verified for completeness and accuracy by 
the Investigator.  A copy of the CRF will remain at the Investigator’s site at the completion of the study. 
15.2 
Data Management Procedures 
The data will be entered into a secure, de-identified, database.  The study coordinators will be responsible 
for data processing, in accordance with procedural documentation.  Database lock will occur once quality 
assurance procedures have been completed. 
All procedures for the handling and analysis of data will be conducted using good computing practices 
meeting FDA guidelines for the handling and analysis of data for clinical trials. 
15.3 
Data Quality Control and Reporting 
After data have been entered into the study database, a system of computerized data validation checks 
will be implemented and applied to the database on a regular basis. The study database will be updated in 
accordance with the resolved queries.  All changes to the study database will be documented. 
15.4 
Archival of Data 
The database is safeguarded against unauthorized access by established security procedures; appropriate 
backup copies of the database and related software files will be maintained.  Databases are backed up by 
the database administrator in conjunction with any updates or changes to the database.   
At critical junctures of the protocol (e.g., production of interim reports and final reports), data for analysis 
is locked and cleaned per established procedures. 
15.5 
Availability and Retention of Investigational Records 
The Sponsor/Investigator must make study data accessible to the monitor, IRB/ and Regulatory Agency 
(e.g., FDA) inspectors upon request.  A file for each subject must be maintained that includes the signed 
Informed Consent, HIPAA Authorization and Assent Form and copies of all source documentation related 
to that subject.  The Investigator must ensure the reliability and availability of source documents from 
which the information on the CRF was derived. 
All study documents (patient files, signed informed consent forms, copies of CRFs, Study File Notebook, 
etc.) must be kept secured for a period of two years following marketing of the investigational product or 
for two years after centers have been notified that the IND has been discontinued.  There may be other 
circumstances for which the Sponsor/Investigator is required to maintain study records. 
15.6 
Monitoring 
Monitoring visits will be conducted according to the U.S. CFR Title 21 Parts 50, 56, and 312 and ICH 
Guidelines for GCP (E6).    By signing this protocol, the Sponsor/Investigator grants permission to the

appropriate regulatory authorities to conduct on-site monitoring and/or auditing of all appropriate study 
documentation. 
15.7 
Subject Confidentiality 
In order to maintain subject confidentiality, only a subject number will identify all study subjects on 
CRFs and other documentation.  
 
 ADMINISTRATIVE, ETHICAL, REGULATORY CONSIDERATIONS 
The study will be conducted according to the Declaration of Helsinki, Protection of Human Volunteers 
(21 CFR 50), Institutional Review Boards (21 CFR 56), and Obligations of Clinical Investigators (21 
CFR 312). 
To maintain confidentiality, all laboratory specimens, evaluation forms, reports and other records will be 
identified by a coded number and initials only.  All study records will be kept in a locked file cabinet and 
code sheets linking a patient’s name to a patient identification number will be stored separately in another 
locked file cabinet.  Clinical information will not be released without written permission of the subject, 
except as necessary for monitoring by the FDA.  The Investigator must also comply with all applicable 
privacy regulations (e.g., Health Insurance Portability and Accountability Act of 1996, EU Data 
Protection Directive 95/46/EC). 
15.8 
Protocol Amendments 
Any amendment to the protocol will be written by the Sponsor/Investigator.  Protocol amendments cannot 
be implemented without prior written IRB approval except as necessary to eliminate immediate safety 
hazards to patients.  A protocol amendment intended to eliminate an apparent immediate hazard to 
patients may be implemented immediately, provided the IRBs are notified within five working days. 
15.9 
Institutional Review Boards and Independent Ethics Committees 
The protocol and consent form will be reviewed and approved by the IRB.  Serious adverse experiences 
regardless of causality will be reported to the IRB in accordance with the standard operating procedures 
and policies of the IRB, and the Investigator will keep the IRB informed as to the progress of the study.  
The Investigator will obtain assurance of IRB compliance with regulations. 
Any documents that the IRB may need to fulfill its responsibilities (such as protocol, protocol 
amendments, Investigator’s Brochure, consent forms, information concerning patient recruitment, 
payment or compensation procedures, or other pertinent information) will be submitted to the IRB. The 
IRB unconditional approval of the study protocol and the informed consent form will be in the possession 
of the Investigator before the study is initiated. This approval must refer to the study by exact protocol 
title and number and should identify the documents reviewed and the date of review. 
Protocol and/or informed consent modifications or changes may not be initiated without prior written IRB 
approval except when necessary to eliminate immediate hazards to the patients or when the change(s) 
involves only logistical or administrative aspects of the study.  Such modifications will be submitted to 
the IRB and written verification that the modification was submitted and subsequently approved should 
be obtained.
