Thelocation of the heart in the body has been studiedsince long before the advent of imaging. Over twothous<strong>and</strong> years ago, Aristotle in ancient Greecetheorized that since the heart was “central, mobile, <strong>and</strong>hot, <strong>and</strong> well supplied with structures which served tocommunicate between it <strong>and</strong> the rest of the body” itmust be a central <strong>and</strong> single structure. Of course, wenow know that as well as pumping <strong>and</strong> relaxationfunctions, the heart has its own electrical conductionsystem, <strong>and</strong> can even produce hormones. As theheart is a relatively superficial organ, it is amenable tophysical examination too. This is the attraction ofcardiology: the study of disease where a diagnosis canbe made by simple history, physical examination, ECG<strong>and</strong> non-invasive imaging tests. Although relatively fewdiseases affect the heart (such as coronary arterydisease), these are common <strong>and</strong> often fatal in latestages. There are many potential therapeutic targets,<strong>and</strong> enormous interest in developing new <strong>and</strong> betterways of diagnosing cardiac disease <strong>and</strong> assessingdisease severity. This underlines the value of cardiacimaging to assess efficacy <strong>and</strong> safety in clinical trials.<strong>Imaging</strong> tests in clinical trialsA variety of imaging techniques are used to image theheart. These use different characteristics of physics tocreate the image. Examples of different imagingmodalities include ultrasound (echocardiography,contrast echocardiography, carotid intima medialthickness, intravascular ultrasound), radioisotopeinjection (single photon electron computed tomography,positron emission tomography), computed tomography,magnetic resonance imaging, coronary angiography,<strong>and</strong> venography. Examples of some imagesacquired by these techniques are shown in Figures 1Figure 1: Cardiac CT image:coronary calcificationto 4. The unique challenge that all of these modalitiesface is the fact that the heart is a functional organwhich moves in multiple different directions, resultingin certain artifacts unless image acquisition is eithertruly “real-time” or is timed to “quiet periods” in thecardiac cycle by ECG gating. Table 1 describes thecommonly used imaging techniques in the clinical trialsetting, together with unique characteristics.These imaging techniques are used in many clinicaltrial settings. Cardiac imaging may be used to directlyassess a cardiac imaging agent or device, or a novelpharmacologic stress agent. Examples of thesestudies are shown in Table 2. Alternatively, imagingmay represent a biomarker of efficacy in studies ofdrugs or devices in the heart failure setting, wherefavorable effects suggest efficacy <strong>and</strong> guide laterstudies in which clinical outcome is an importantdeterminant of regulatory approval. Examples areshown in Table 3.continued on page 244021 US.indd 3 12/1/08 10:19:45 AM

This ismost often found where animal studies suggest possible signal forsafety concern, or where cardiac toxicity is a known class effect fortoxicity. Some examples are shown in Table 4.Role of the Central <strong>Imaging</strong> Core Laboratory<strong>Imaging</strong> studies in some clinical trials are performed <strong>and</strong> interpretedat clinical sites according to st<strong>and</strong>ard of care. This is not idealin the clinical trial setting, since it introduces bias in the way thatimages may be acquired or interpreted, without the use of a singlemethodology or ability to query potentially erroneous findings (orbeneficial ones). In the worst case, false documentation of asafety concern could mean withholding of chemotherapy.Conversely, missed cardiac toxicity could lead to early mortalityinduced by an experimental drug. The role of a central lab is toprovide medical, technical, statistical, operational <strong>and</strong> regulatoryexpertise to the imaging study. Good st<strong>and</strong>ardization <strong>and</strong> trainingshould avoid such false signals <strong>and</strong> ensure high quality data.It is clearly essential that sites have adequate equipment to acquire<strong>and</strong> archive images, <strong>and</strong> have adequately qualified staff, who areprepared to be trained on the particular protocol. This can beproblematic, as in some studies the <strong>Imaging</strong> laboratory has onlylimited relation to the investigator. Good communication betweenthe clinical CRO, core laboratory, imaging laboratory <strong>and</strong> studycoordinator is key.It is very important for the core laboratory to consult with thesponsor in the objectives of the study so that the most suitableIt is clearly essential that sites have adequateequipment to acquire <strong>and</strong> archive images, <strong>and</strong>have adequately qualified staff, who are preparedto be trained on the particular protocol.Table 3: Examples of use of <strong>Imaging</strong> as a biomarker of EfficacyProduct Indication <strong>Imaging</strong>ModeIntracardiac deviceto exclude cardiacaneurysm from thecirculationHeart FailureEchoMRICTEndpointImprovement inventricular functionor cardiacoutput.Novel inotropes Heart Failure Echo Improvement inventricular functionor cardiacoutput.Novel gene therapy Heart Failure EchoMRICTSPECTPETPulmonaryvasodilatorLipid loweringtherapyPulmonaryhypertensionHyperlipidemiaEchoIntravascularultrasoundImprovement inventricular functionor cardiacoutput or perfusion,or viability.Effect on pulmonarypressure <strong>and</strong>resistance.Reduction inatheroscleroticplaque.continued on page 444021 US.indd 5 12/1/08 10:19:46 AM

Optimal design would then lead to the creation of an<strong>Imaging</strong> charter, appropriate statistical endpoints, an image acquisitionmanual, system release specification <strong>and</strong> design <strong>and</strong> validationof the electronic case report form. <strong>ICON</strong> Medical <strong>Imaging</strong> (IMI) hasdeveloped a proprietary online platform, MIRA, for image viewing<strong>and</strong> measurement that can apply to multiple modes. Alternatively,for some imaging modalities such as quantitative coronaryangiography, 3rd party software may be incorporated with MIRA<strong>and</strong> linked to an eCRF.Regulatory aspects are very important, as all aspects of imageh<strong>and</strong>ling are potentially open to audit by the sponsor or FDA.Ultimately, all cardiac imaging studies will succeed or fail based upon theimage interpretation. Sometimes a software-only interpretation may beused, but due to artifacts this is rarely used for any primary analysis incardiac studies. Thus, image interpretation generally involves preliminaryquantitation by a technologist, or a cardiologist over-read, or both. Theexperience <strong>and</strong> attention to detail of the reader is critical, but so is thetraining of the reader on sample cases <strong>and</strong> feedback if errors are made.Variability is assessed by inter <strong>and</strong> intra-reader variability testing for keyparameters.The majority of pharmaceutical <strong>and</strong> biotechnology industry sponsoredclinical trials requiring cardiac imaging have used core laboratories fromthe academic sector. <strong>ICON</strong> Medical <strong>Imaging</strong> can offer a unique combinationof academic experience <strong>and</strong> superior technology to address all ofthe requirements of a clinical trial requiring imaging.Figure 4: Quantitative 2 Dimensional Echocardiography44021 US.indd 6 12/1/08 10:19:48 AM


Pg 05Conventional Safety Markers <strong>and</strong> Potential Future DirectionsJoseph Schappert, MD l Medical Director, <strong>ICON</strong> Central LaboratoriesIntroductionPatient safety is a major issue in clinical practice, as it is in clinicaltrials. The laboratory contributes to assuring patient safetythrough the provision of accurate results <strong>and</strong> reports, timely resultreporting, reporting of alert or ‘panic’ values to the clinical staff,etc. 1 But since the utilization of ‘ … quantitative measures ofbiologic effects that provide information links between mechanismof action <strong>and</strong> clinical effectiveness … (<strong>and</strong>) predict effectivenessare needed to guide drug development’, 2 this article will focus onproper utilization of laboratory tests <strong>and</strong> their limitations forassuring the safety of subjects in clinical trials.Since drug related toxicity is often reversible, particularly when it isdetected early, the availability of markers, which accurately assessacute injury to vital organs is an important goal. Biomarkers withpoor predictive value for the detection of toxicity provide littleconfidence in decision making <strong>and</strong> may produce false reassurances<strong>and</strong>/or unwarranted concerns. Better biomarkers shouldassist in identifying signs of toxicity earlier in the product life-cycle.Since the development <strong>and</strong> further assessment of many agents forwhich ambiguous signs of toxicity are observed are dropped fromthe development pipeline, even though they often have shownpromising results in subjects without these, better delineation oftheir toxicity with biomarkers may result in patients who needthese agents <strong>and</strong> who would not exhibit toxicity having access toan important therapeutic option. But since clinicians exhibitreluctance to including novel biomarkers into protocols, preferringto rely on more traditional <strong>and</strong> better known assays, biomarkeradoption may not be facile.This overview addresses conventional safety markers <strong>and</strong> potentialfuture directions for the laboratory assessment of cardiotoxicity,nephrotoxicity <strong>and</strong> hepatotoxicity.CardiotoxicitySince 9% of withdrawals of prescription drugs from worldwidepharmaceutical markets are due to cardiotoxicity, 3 <strong>and</strong> approximately17% of pharmaceuticals in clinical trials produce cardiovasculartoxicity, cardiovascular toxicity is a major safety concern. 4Cardiotoxicity is also a limiting factor in the utilization of a widevariety of therapeutically important agents (e.g., oncology,anti-retroviral therapy, etc.)Cardiac troponin (cTn) is currently the most effective biomarker ofmyocardial injury. 5 Troponin is a globular protein, with three forms,I (cTnI), T (cTnT), <strong>and</strong> C (TnC), which regulates actin-myosininteractions in the myocardium. 6 Since 2000, cTn has beenrecommended by the American College of <strong>Cardiology</strong> <strong>and</strong> theEuropean Society of <strong>Cardiology</strong> as the preferred biomarker foracute myocardial injury. It has high sensitivity, good specificity, <strong>and</strong>plays an important role in risk stratification. Since elevations introponin, which may be within the reference range, occur beforechanges in left ventricular ejection fraction, its utilization has alsobeen extended to the assessment of a number of pathologies,including drug related cardiotoxicity, renal disease, unstableangina, etc. 7Brain natriuretic peptide (BNP) is a neurohormone, which iselevated in response to volume overload. BNP is widely utilized asa biomarker of congestive heart failure (CHF) but elevations arealso associated with impairment of left ventricular function. 8 Dueto their lack of tissue sensitivity <strong>and</strong> specificity, particularly in thepresence of skeletal muscle injury, classical markers of cardiotoxicity(lactate dehyrogenase [LDH], creatine kinase [CK] <strong>and</strong> itsisoenzymes <strong>and</strong> myoglobin) have been superceded by cTn, <strong>and</strong>44021 US.indd 7 12/1/08 10:19:54 AM


Pg 06Patient safety is amajor issue in clinicalpractice, as it is inclinical trials.to a lesser degree by BNP. A translational biomarker of potentialinterest is fatty acid binding protein 3 (FABP3), which has anintracellular transport function for long chain fatty acids. Sincetroponin is bound to a structural component of the myocardium,the location of FABP3 in the cytosol results in higher concentrationsof FABP3 earlier than troponin, <strong>and</strong> greater sensitivity toacute myocardial injury. The major issue with FABP3 as abiomarker for cardiotoxicity is its lack of specificity in the presenceof muscle injury or renal failure.NephrotoxicityThe accurate <strong>and</strong> timely assessment of renal function is essentialto assuring the safety of subjects enrolled in clinical trials. While‘acute renal failure’ (ARF) has traditionally been utilized to describeacute renal dysfunctions, ranging from mild prerenal azotemia tosevere oliguria associated with acute tubular necrosis, the term‘acute kidney injury’ (AKI) has recently been adopted. ARF isreserved for patients who have AKI <strong>and</strong> who require renal replacementtherapy (dialysis or renal transplantation).AKI has been variably defined as an increase in serum creatininevalues of 100%, of 50% <strong>and</strong> of 0.3 mg/dL over differing timeintervals. Conventional serum renal function tests (serum creatinine<strong>and</strong> urea nitrogen) are late markers of nephrotoxicity. Theirelevations are associated with relatively advanced <strong>and</strong> severedamage to the proximal tubule on histopathologic examination.Due to their lack of sensitivity <strong>and</strong> their failure to accurately reflectrapid changes in renal function, the utilization of conventionalmarkers can result in delays in therapeutic decision making, witha potential impact on outcomes. Conventional markers also lackspecificity. For example, creatinine values vary with changes inmuscle mass <strong>and</strong> tubular secretion, have a wide reference interval,<strong>and</strong> are impacted by nonrenal factors (e.g. body weight, race, age,sex, total body volume, drugs, muscle metabolism <strong>and</strong> proteinintake; prerenal factors; <strong>and</strong>, postrenal factors).The lack of sensitive <strong>and</strong> specific renal biomarkers may haveimpaired progress in this field, with mortality rates for severe acutekidney disease stable over the past 50 years. It has also had adetrimental effect on the design <strong>and</strong> the assessment of outcomesof clinical trials. To address this, the design of panels consisting ofbiomarkers, intended to increase sensitivity <strong>and</strong> specificity <strong>and</strong> topermit the identification of AKI subtypes, are currently in thediscovery, development, translational <strong>and</strong>/or validation phase.These biomarkers include neutophil gelatinase-associatedlipocalcin (NGAL), kidney injury molecule-1 (KIM-1), interleukin-18(IL-18), <strong>and</strong> cystatin C. 9NGAL is a growth <strong>and</strong> differentiation factor found in the tubularcells of the kidney. 10 It is involved in the intracellular transport oflow molecular weight molecules <strong>and</strong> is a sensitive, specific <strong>and</strong>predictive early marker of AKI. Following ischemic or nephrotoxicAKI, NGAP is upregulated, with serum levels increasing 10 fold<strong>and</strong> urine levels increasing 100 fold in 2-6 hours. NGAL has beenshown to be an independent predictor of clinical outcomes <strong>and</strong>duration of AKI. Cystatin C, a member of the cystatin ‘superfamily’of protease inhibitors, is freely filtered by the glomerulus. Unlikecreatinine, it is not affected by age, gender, race or muscle mass.44021 US.indd 8 12/1/08 10:19:56 AM


Pg 07Hepatotoxicity is the single most frequent cause of new drug application (NDA) disapprovals, limitations onutilization, <strong>and</strong> withdrawals of approval submissions by the FDA.A 50% increase over a 12 hour period is predictive of AKI. Itsmajor disadvantages are great intraindividual (‘biologic’) variation<strong>and</strong> lack of specificity (elevations observed in malignancy, HIVinfection, glucocorticoid therapy, etc). But in association with otherbiomarkers <strong>and</strong> in the proper clinical setting, cystatin C may beanticipated to play an important role in the identification of acutekidney injury. Il-18 is a proinflammatory cytokine, which is cleavedin the proximal tubule <strong>and</strong> released into the urine in response toAKI. It has demonstrated effectiveness as an early marker of AKI<strong>and</strong> in the differential diagnosis of acute tubular necrosis. KIM-1 isan immunoglobulin superfamily cell surface protein, whichrecognizes apoptotic cell-specific surface proteins. 11 It is notexpressed on myeloid cells. During ischemic or toxic AKI, KIM-1 ismarkedly induced in the proximal tubules, <strong>and</strong> differentiates AKIfrom prerenal azotemia, chronic renal disease <strong>and</strong> urinary tractinfection. At 12 hours, it is a predictive biomarker for clinical12, 13outcomes, including dialysis <strong>and</strong> death.By identifying the primary location of injury (proximal tubule, distaltubule, interstitium, or vasculature) <strong>and</strong> the duration, course <strong>and</strong>pathogenesis of AKI (see Table 1), the differential expression ofbiomarkers, such as these, may be anticipated to assist in theearly identification <strong>and</strong> classification of AKI, to provide riskstratification <strong>and</strong> prognostic information, <strong>and</strong> to expedite the drugdevelopment process.HepatotoxicityOver the past 50 years, hepatotoxicity is the single most frequentcause of new drug application (NDA) disapprovals, limitations onutilization, <strong>and</strong> withdrawals of approval submissions by the FDA.Unpredictable hepatotoxic reactions are unrelated to dose, occurwithout warning, <strong>and</strong> have latency periods of days to 12 months.Drug-induced liver injury (DILI), particularly idiosyncratic toxicities,is observed with low frequencies (

But based onthe rapid growth of our knowledge in genomics, transcriptomics,proteomics, <strong>and</strong> metabolomics <strong>and</strong> the ensuing growth in thediscovery <strong>and</strong> development of novel biomarkers, it should beanticipated that the clinical laboratory will assume an even greaterrole in the provision of safety testing in the future.Resources1H<strong>and</strong>ler S, Altman R, Perera S, et al.

Pg 09Technological advances in clinical trial managementKris Gustafson l Sr. Vice President & Global Head, Interactive Technologies <strong>and</strong> Lifecycle Sciences Group<strong>ICON</strong> Clinical ResearchTwenty years ago, pharmaceutical researchers looked forward tothe day when advances in technology would reduce or eveneliminate the truckload of paperwork required for a typical NDAsubmission. Many in the industry visualized an all-electronicclinical trial, <strong>and</strong> sophisticated software that could track patients,analyze data, resolve queries, prepare reports, create models,send alerts <strong>and</strong> even project outcomes, based on biochemical<strong>and</strong> genetic data.That day is here. Today, every clinical trial in the world relies onelectronic tools for data management <strong>and</strong> communications.Researchers use an array of tools that didn’t even exist 20 yearsago. From laptops <strong>and</strong> Blackberries, from electronic CRFs to IVRphone systems, the clinical trial of <strong>2008</strong> is critically dependent onthe silicon chip. And as studies become larger, more globalized,<strong>and</strong> more logistically complex, technology will play an evenbigger role.A profound shiftIn 2004, an article in Applied Clinical Trials noted that:“The use of paper in offices, from the printing of emails <strong>and</strong> Webpages, is growing at 6-8% per year, with the average employeeprinting 33 Internet pages per day. Paper usage doubled from1981 (the introduction of the PC) to 1995. We still print out ourdocuments to read <strong>and</strong> review, keep paper to-do lists, <strong>and</strong> getour industry news in printed magazines.” 1It is an indication of how fast things change today that thesewords, written just four years ago, already feel out-of-date. Forone thing, an increasing number of people – including clinicalresearch <strong>and</strong> pharmaceutical professionals – are more comfortablethan ever communicating, learning <strong>and</strong> archiving informationin an online-only environment.Trend analysts <strong>and</strong> learning experts agree that the shift to avirtually paper-free world is gaining speed. As this happens, it isprofoundly changing the way human beings process information.Even highly educated people today have noticed a difference inthe way they read <strong>and</strong> absorb information. Many are finding itharder to focus on information presented in long-format text,preferring spreadsheets, graphics <strong>and</strong> short paragraphs –formats that are ideally suited for the electronic environment.As technology grows more powerful <strong>and</strong> pervasive,we will see significant changes in the way clinical trialinformation is gathered, organized <strong>and</strong> presented.Technology trends in clinical trialsOver the last decade, pharmaceutical, biotech companies <strong>and</strong>CROs have been implementing an increasing array of technologicalresources. Over this period we have watched as cutting-edgetrends have become established industry practices. Here are themost popular clinical trials technologies – <strong>and</strong> a few trends towatch.EDC (Electronic Data Capture)After an uncertain start in the 1990s, electronic data capture ishere to stay. Many of the initial drawbacks (including high softwarelicensing fees) have been addressed successfully, <strong>and</strong> there is anincreasing comfort level among sponsors <strong>and</strong> sites.There are many advantages to EDC beyond the reduction ofpaperwork. Real-time data checking can reduce queries <strong>and</strong>prevent costly errors from compounding. Regulatory submissionsare simplified. But perhaps even more significantly in today’s cost<strong>and</strong>safety-conscious environment, EDC can be used to conductprospective clinical trials on experimental compounds. The datafrom these prospective trials can help identify “winners” <strong>and</strong>“losers” before millions of dollars in research <strong>and</strong> developmentcosts are invested.IVRS (Interactive Voice Response Systems)Interactive Voice Response Systems are used extensively today astools for clinical trial management. These systems use telephonesto collect study data. While not as leading-edge as other technologies,IVRS has been successful precisely because it employs atechnology that is familiar everywhere. It has become particularlyuseful in emerging nations, where l<strong>and</strong>-based telephone systemsmay be lacking <strong>and</strong> where cell phones are used by the majority ofthe population.44021 US.indd 11 12/1/08 10:20:02 AM


Pg 10IVRS systems have been used successfully to speed data capture,r<strong>and</strong>omize study subjects, manage <strong>and</strong> track clinical supplies <strong>and</strong>issue reminders <strong>and</strong> alerts.ePRO (Electronic Patient-Reported Outcomes)Many clinical studies today rely on some form of patient diaries tocollect patient reported outcomes (PRO). PRO can provide vitalendpoint data <strong>and</strong> are therefore critical components of many trials.Traditionally, these diaries were paper documents – forms thatstudy subjects would fill in manually. However, paper-basedsystems have serious drawbacks:• Labor intensive: Study personnel must collect diaries, processinformation <strong>and</strong> perform quality checks• Costs of printing <strong>and</strong> distribution• Patients can lose diaries• Because diaries remain in patients’ h<strong>and</strong>s, errors <strong>and</strong> omissionsmay not come to light until the end of a studyIn comparison with paper-based PRO, ePRO, which uses Internettechnology for patient data collection <strong>and</strong> communication, hasseveral advantages.RFID tag. RFID st<strong>and</strong>s for “radio frequencyidentification device.” It’s the same technologythat’s used in credit cards, where a small striprecords unique identification about how you useyour card. Similarly, the eCap can record when amedicine container is opened, thus helping keepa record of patient compliance. RFID technologycan also be used on blister-packs, to recordwhen the seal is broken <strong>and</strong> a pill is removed.Data WarehousingIntegration of various systems within clinical trials has becomemore common than ever before. EDC systems often requireenrollment data from the IVRS. The IVRS requires site data fromthe CTMS. Each integration is often built on a study specific basisfor each technology vendor. The possibility of errors <strong>and</strong> datainconsistencies is enormous <strong>and</strong> the data flow diagrams look like apile of spaghetti. A central data repository, based on CDISC,would allow each vendor to build a reusable data integrationmodule. The data warehouse would allow consistent reportingacross multiple studies. In addition we would be able to reducethe time required to setup these systems in the beginning.http://ecap.biz eCapAdvantages of ePRO• Eliminates problems associated with paper diaries• Greatly increases patient compliance 2• Reminds patients of important study activities (site visits, dosechanges, etc.) with pre-programmed alarms, voice mailmessages or e-mails• Monitors data entry compliance in real time <strong>and</strong> issuesreminders, thus preventing missed entriesRegulatory agencies today look favorably on ePRO data as itprovides an excellent record of patient activity, <strong>and</strong> in most casesis more complete <strong>and</strong> accurate than paper diaries. Indeed, thenumber of clinical trials using ePRO continues to increase, fromapproximately 5% in 2002 to 15% in 2007. 3ePRO as a feasibility toolDropping non-compliant patients from a study is costly – but whatif you could predict in advance which patients would be non-compliant<strong>and</strong> correct the problem before the study started? Somesponsors are running pre-studies using placebos to learn whatfactors lead to non-compliance. Armed with this information, theycan design appropriate patient education materials, or refineprotocols to weed out subjects likely to be non-compliant. ePROtechnology can be invaluable in speeding up this process.eCapsOne novel use of technology that has recently appeared on thescene is the eCap. An eCap is a medicine bottle cap with a built-inPractical considerationsWhat does all this mean for clinical research professionals? Astechnology grows more powerful <strong>and</strong> pervasive, we will seesignificant changes in the way clinical trial information is gathered,organized <strong>and</strong> presented. Regulatory agencies are likely to changetheir requirements to favor new forms <strong>and</strong> formats for electronicallypresented data. Clinical professionals who can work comfortably<strong>and</strong> creatively with technology will have the edge in the industry,making it even more critical to select <strong>and</strong> implement the mostefficient e-tools.Notes1Paul Bleicher, “The Fully Electronic Office (or Clinical Trial) Myth,”Applied Clinical Trials, October, 20042Stone AA, Shiffman S, Schwartz JE, Broderick JE, Hufford MR.“Patient non-compliance with paper diaries.” Br Med J2002;324:1193-1194.A National Cancer Institute (NCI) study reported that patientcompliance levels for electronic diaries were higher than for paperdiaries. The study also showed a large discrepancy betweencompliance levels reported by patients with paper diaries (90%reported) <strong>and</strong> their actual levels of compliance (11% actual). Incontrast, actual compliance with electronic diaries was 94%.3Gustafson, Kris, “ePRO – maximizing the benefit <strong>and</strong> minimizingthe pain,” World Pharmaceutical, April 17, <strong>2008</strong>44021 US.indd 12 12/1/08 10:20:03 AM
