ForewordA cancer biomarker is a molecule either produced by the cancer or by the body in response to a cancer that can be measuredin blood, body fluid or tissues and indicates the presence or status of the cancer. Biomarkers associated with altered (mutated)genes can be used to screen for the risk of developing cancer. They can be used to help diagnose cancers. They may indicatetargets for treatment and then give information on dosing by indicating how easily the body will eliminate the drug. They can beused to monitor treatment response and subsequently recurrence of a cancer.What has made the use of biomarkers essential is the advent of personalised medicine. Advances in genomics, which describethe mutations in genes which are responsible for the growth of cancers, has allowed targeted therapies to prevent thatgrowth. Moreover, at the time of diagnosis, cancers which share the same mutations may respond to the same targeted drugs.Determining treatment by the genetic make-up of a cancer may be more important than by using the organ of origin, which hasbeen the traditional practice.An optimal set of biomarkers is required to accurately detect the cancer, to predict its severity and to determine which treatmentstrategy is most appropriate. Further, the presence of biomarkers will enable drugs to be prescribed specifically to patients whosetumours have the targets, allowing those without to avoid the side effects and cost of being treated with drugs which are unlikelyto be effective. In trials, response to treatment as measured by a decrease in the biomarker, will occur much earlier than waiting fora survival advantage, so that biomarkers may be earlier surrogate markers of the success of a new drug. This will enable drugs tobe provisionally approved for widespread use until a survival advantage can be demonstrated.To take advantage of the optimal use of biomarkers, methods for standardising the timely assessment of their efficacy need to bedeveloped. Regulatory frameworks need to be developed to approve and fund the testing for biomarkers. This is especially thecase when biomarkers are companion diagnostic tests for targeted drugs to ensure the most cost-effective use of targeted drugs.Patent law must not become a barrier for global access to biomarkers.This report reviews the evidence for the efficacy of biomarkers and examines overseas precedents for their regulation andthe Australian context. It also reports on the opinions of the end-users of biomarkers who are ultimately responsible for theirmeasurement being translated into improved patient care and outcomes.Professor Ian Olver AMProfessor of Translational Cancer ResearchDirector Sansom Institute for Health ResearchUniversity of South AustraliaCancer Biomarkers In Australia3

Executive summaryBACKGROUNDRECOMMENDATIONSIn cancer therapy, there has been a major shift from nonspecific cytotoxic drugs that indiscriminately kill cells totargeted small molecules, monoclonal antibodies andimmune regulators. At the same time, cancer biomarkersare increasingly being used for screening and diagnosis,prognosis and as surrogate endpoints in cancer therapy trials.In particular, they are being used co-dependently with cancerdrugs to stratify the patient population into those for whomthe treatment is most likely to be successful, and those forwhom the side effects will be fewer. We are also now seeingmore flexible, but more complex study designs that arebeginning to replace standard trials of new cancer drugs.1.In response to these and other innovations such as orphandrugs, regulatory authorities in many countries are modifyingor changing the ways in which drugs or drug-biomarkercombinations can be licensed and funded. Australia’sregulatory authorities have recognised the need for change,but still lag behind many OECD countries in this regard.METHODSTo address these issues, we have undertaken:1.An overview of current international and Australian policyon cancer biomarkers;Allow approvals and reimbursement of targeted drugsto be based on the genomic similarities of cancersexpressing the target, rather than approving drugs onlyon histopathology.2. Align the approval and funding of a targeted drug with thatof its co-dependent biomarker, preferably by the sameagency where end-user benefit can be a part of decisionmaking.3. Allow provisional drug approval based on surrogatebiomarker endpoints.4. Develop standards for evaluation of biomarkers aspredictive tools.5. Develop bioinformatics capabilities to analyse largegenomic datasets.6. Develop electronic health records and laboratory systemsto allow for capturing and linking biomarker tests and data.7.Develop guidelines for the use of biomarkers.8. Ensure that patent law does not restrict biomarkerdevelopment.2. A review of the published literature for selectedbiomarkers;3. A survey of Australian experts in cancer biomarkers;4. Interviews with key players in the cancer biomarker arena.FINDINGSThe survey of experts found a high use of biomarkers, butonly just under half of the respondents thought they werereliable. Respondents called for better trials to demonstratethe efficacy of biomarkers, and agreed that biomarkerdevelopment and validation would be more successful ifthe biomarker can be shown to be part of the underlyingpathological process of tumour development.More detailed interviews with stakeholders focussed on thefunding issues of pairing a drug to its biomarker. Stakeholderscommented on the potential for risk sharing amongst thosewho would benefit from this pairing, such as those whodeveloped the testing technology. They were interested inregulatory models that would mandate pairing a targeted drugwith its biomarker as a condition of funding the drug. Theyalso recognised the difficulty of designing and interpretingbiomarker trials.Cancer Biomarkers In Australia5
OVERVIEW OF THE LITERATURECancer biomarker policyBACKGROUNDIn 1998, the National Institutes of Health BiomarkersDefinitions Working Group defined a biomarker as “acharacteristic that is objectively measured and evaluatedas an indicator of normal biological processes, pathogenicprocesses, or pharmacologic responses to a therapeuticintervention.”1 Clinical biomarkers can be broadly classifiedinto those used for diagnosis, prognosis, prediction, asurrogate endpoint, and those that can identify a potentialtarget against which a therapeutic agent can be produced andto which it can be directed. Some biomarkers can fit into morethan one category.2,3Diagnostic biomarkers are used to detect or confirm thepresence of a disease or condition of interest, or to identifyindividuals with a subtype of the disease. For example, geneexpression profiling may be used as a diagnostic biomarkerto segregate patients with diffuse large B-cell lymphoma intosubgroups with different tumour cell of origin signatures.4A prognostic biomarker provides information about thepatients’ overall cancer outcome, regardless of therapy.A clinically useful prognostic marker must be a provenindependent, significant factor that is easy to determine andinterpret and has therapeutic consequences.5 For example,oestrogen receptor-positive (ER-positive), progesteronereceptor-positive (PR-positive) and HER-2 expression areprognostic biomarkers in breast cancer.Predictive biomarkers allow clinicians to target patients whoare likely to respond positively to a treatment. This has thepotential to reduce the cost of drug development by reducingthe size of the study population required to demonstratesafety and efficacy. Further, by demonstrating that a drug willonly be effective for a particular subset of patients, this canreduce the number of patients having adverse side effects,and the cost attached to providing the drug to patients inwhom it will be ineffective.Biomarkers can also be used as surrogate endpoints.6 Thesecan be measured sooner than the classical clinical endpointsthey substitute for, and thus have the potential to reduce thelength and cost of clinical trials. To date, few biomarkers havemet necessary regulatory standards to be used in formal drugor clinical trials.7Some “classic” examples of cancer biomarkers includethe protein PSA for prostate cancer (screening/diagnosis/6Cancer Biomarkers In Australiaprognosis), the BRCA 1/2 genes for breast and other cancers(prognosis), the FMC7 cell surface antigen CD20 on B-cells(differential diagnosis of lymphoma and leukaemia), HER2 forbreast cancer (prognostic/predictive), CA 19-9 for pancreaticand other cancers (diagnostic/predictive), and CA-125/MUC16antigen for ovarian and other cancers (diagnostic). While thesebiomarkers are used in clinical practice, their performanceis not always optimal. This is the case with PSA, which wasoriginally developed as a prognostic marker only, and thenadapted for screening and diagnosis; unfortunately, PSA hasmajor problems with specificity that question its usefulnessin diagnosis. This highlights a significant problem in thebiomarker field, with a need for strict guidelines for biomarkerdevelopment, validation and implementation and use - sothat governments and medical institutions can rationalize andjustify the use and funding of biomarkers in clinical practice.To date there has been a lack of progress in biomarkerdevelopment due to the difficulties in discovering suitablecandidates, verifying that the biomarker is genuine, properclinical evaluation and commercialisation. The US Food andDrug Administration (FDA) has recognized the potential forbiomarkers and the emerging field of pharmacogenomicsto transform drug development. The FDA is committedto advancing the development and use of biomarkers bymodifying its regulatory review processes.Biomarkers have been used in a diagnostic capacity inmedicine for decades, with biomarkers having a wide varietyof analytical targets, including metabolites, nucleic acids,proteins, lipids and unusual entities such as exhaled gases.This usage is further encouraged by the range of laboratorybased and ‘near patient’ point of care (PoC) platforms anddevices available commercially.There are several areas in which diagnostics for cancerneed to be improved including: primary disease diagnosis,prediction of disease course, and for monitoring treatmenteffect and disease recurrence. It is currently a commonrequirement for many treatment efficacy trials to have apaired diagnostic test to monitor outcomes.Another potential pathway for biomarkers is for follow-oncare, especially in patients thought to be at elevated risk.Until recently, a barrier to this was that the utility of biomarkerclinical studies were mainly confined to single or dual use,and the landscape was multifaceted. One example of this isthe diagnostic and predictive dual use of beta HCG and alphafetoprotein for testicular cancer.
Biomarkers in future might be delivered by “omics”technology in disciplines such as genomics, proteomics ormetabolomics.8 Further, since single biomarkers often lackspecificity or sensitivity, a multi-biomarker approach might benecessary to achieve diagnostic accuracy.9To continue the progression of biomarker use in a diagnosticcapacity, there is a requirement to detect disease pathologyearly in clinical progression. This can be achieved throughtests that have high specificities and positive predictivevalues. Presently the majority of biomarkers that are availablehave high negative predictive values. The degree of specificityis an area of debate, thus larger complex panels could proveto be superior to single or low-complexity panels in thiscapacity.10 This objective is more likely to be achieved by acombination of biomarkers in a score-like test.10 Cancer isone of the areas in which there has been continual progressfor biomarkers,11 with it being one of the first fields withcommercially available diagnostic and stratification tests.REAPING THE BENEFITS OF BIOMARKERSThese changes may also have positive economic outcomes: Regulators and third-party payers may have a reducedrisk of accepting cost-ineffective drugs; there will bea smaller variation in patient response and fewer sideeffects. The cost of drug development will likely decrease. At thesame time, biomarkers should speed drug delivery andimprove safety and efficacy.There are many challenges before biomarkers are widelyadopted into personalised medicine. In particular, theexisting regulatory framework lacks sufficient adaptionto these diagnostic and prognostic tests. New evidentiarystandards are required to introduce these new tools into thehealthcare system. Current reimbursement mechanisms donot reflect the value of these new technologies and newbusiness models are required to develop this new industry.Nonetheless, we are seeing rapid progress in the research anddiscovery sectors.The current reactive ‘one-size-fits-all’ healthcare modelapproach could be revolutionised by novel molecularbiomarkers transforming to an increasingly proactive andpersonalised approach. A personalised approach or ”personalmedicine”, as it has been termed (also called “precisionmedicine” or “stratified medicine”) would be effective throughtreatments directed by the information contained within apatient’s genetic profile; where cancer may be diagnosed,controlled or possibly prevented when the disease is initiallydetected. Novel molecular information and biomarker-basedtests will enable practitioners to optimise treatment strategiesas a supplement to their current treatment approach. We arenow able to tailor treatments to the molecular characteristicsof patient sub-groups. This enables us to minimise side effectsand to improve the efficacy of treatments. Incorporatingbiomarker-based technologies into cancer diagnosis andtreatment has many potential benefits:THE GENOMICS REVOLUTION Earlier detection can improve health outcomes andminimise treatment costs. The use of pharmacogenetics can increase the safety andefficacy of treatments and reduce side effects. The use of biomarkers in pharmacogenetics will allowan increased number of safe and effective treatmentsto become available as drug development costs andtimelines are reduced.Advances in cell and molecular biology are increasingly beingused to develop new diagnostic, prognostic and therapeutictools. Biomarkers can be used in their own right as adiagnostic test or as companion diagnostics, i.e., tests directlyassociated with a therapy. Biomarkers are also increasinglybeing used in a number of pharmacogenetic applicationsincluding drug development, the characterisation of diseasesand progression pathways. Several types of biomarkers can beidentified (see Figure 1). Cytotoxic side effects can be reduced if the biomarkeris associated with a process that occurs in cancersbut not the surrounding tissues. However, currentimmunotherapeutic treatments have their own sideeffects.Genomics has allowed us to study and better understandindividuals’ different responses to disease and treatment,and is allowing us to tailor diagnostic tests, treatment andmonitoring to the individual. Further, our response to diseaseand drugs can be linked to biomarkers. The sequencing ofthe human genome in 2001 has heralded new insights intopatterns of DNA sequence variation. Advances in technologyand bioinformatics has allowed us to examine genomedifferences between individuals and individual susceptibilityto cancer and response to drugs. This new technology givesus greater insight into the disease process in different cancersbased on biomarkers. Pharmacogenomics will assist a morerapid development of new drugs and targeted therapies.APPLICATION OF BIOMARKERS IN PERSONALISEDMEDICINEOPPORTUNITIES AND CHALLENGESIn OECD countries, cancer is a leading cause of death.Importantly, one third of these deaths could have beenprevented, and another third cured if detected in time. Thishas placed a substantial cost on these countries due tothe care required.12 The World Health Organization (WHO)Cancer Biomarkers In Australia7
suggests that in 2030, cancers will overtake ischemic heartdisease as the leading cause of death.13 In 2008, close to72% of cancer deaths occurred in low and middle-incomecountries which have lower incidence rates, but poorersurvival. The global economic cost due to cancer notincluding patient care is approximately 900 billion US dollarsper year – higher than that of heart disease.14 All governmentsare faced with increased healthcare costs, a major componentof which is the cost of pharmaceuticals, and the preventionand treatment of chronic disease. Biomarkers may offer apotential way to reduce these costs.FIGURE 1 - RAPID LEARNING SYSTEM FORBIOMARKER TESTS FOR MOLECULARLY TARGETEDTHERAPIES15Processes to Improve Patient CareSupportive Policy EnvironmentCommon Evidentiary standards forassessment of clinical utility (1)Expanded equity in access tobiomarker tests and expertisefor effective use of test resultsin clinical decision making (8)Integrated FDA-CMS Review forcoordinated regulatory, coverage,and reimbursement decisions (2)Standardized labelsto communicate testperformance characteristicsand intended use (3)PatientsEnhanced specimen handlingand documentation standardsto ensure quality of testing andsafeguard patients (9)Strengthenedlaboratory oversightand accreditation (4)Ongoing assessmentof clinical utilitythrough reimbursementmodels, rapid learning,and research fundingapproaches (5)Improved processes fordeveloping and updatingclinical practice guidelinesthrough interdisciplinarycollaboration (10)Supporting Data InfrastructureEHR/LIS with structured data for biomarker testdetails, results, treatment, and outcomes; integratedCDS, and CE for use (6)National database for biomarker test details, results, treatment,and outcomes data; appropriate data security, de-identification andsharing policies; incentives for data submission (7)8Cancer Biomarkers In Australia
PHARMACEUTICAL CONTEXTPharmaceuticals are currently an essential componentof the prevention and management of cancers. However,drug discovery and development is taking longer, and isincreasingly more expensive. Much of the cost is linked topoor target identification and validation, and to late failureof promising therapies. The inclusion of pharmacogenomicsinto the process has the potential to speed up drug discoveryand delivery, and reduce costs. In particular, biomarkers canenhance the identification of drug targets, thus allowing theidentification of patients likely to respond to a drug. This willreduce the likelihood of attrition of new compounds, reducethe size, time and cost of drug trials by using biomarkers assurrogate endpoints, and reduce the risk of side effects inpatients.CLINICAL CONTEXTThere are already a number of diagnostic andpharmacogenetics-based tests currently available. They canassist in the diagnosis of subclinical disease, help identifylikely responders and non-responders, help in establishing theappropriate dose for responders, and flag those patients likelyto suffer from adverse reactions or side effects.BIOMARKER IDENTIFICATION AND VALIDATIONTo date there have been too few clinical trials allowingbiomarker selection; those that have been undertakenhave often been underpowered. Studies undertaken haveused genomic and gene expression-type platforms,16 andmetabolomics and protein analyses. Running sufficientlypowered biomarker studies is complicated by regulatory,ethical and clinical concerns. Further, the generation of vastamounts of data on a relatively small number of patients hasrequired the development of new bioinformatics tools. Otherissues include the need: to stratify patients to ensure cleandatasets, for secondary confirmation of results, for multipleinterrogation pathways, for robust meta-analyses. Withrespect to the latter, there is now a trend for integrative crosscomparative analyses across published datasets,17 which areavailable from publically accessible databanks.Another barrier to development, especially for nucleic acidbased markers, is the slow development of platforms andtechnologies. More progress is required to improve platformand assay development and sample preparation before thesedevices will be at the required technology stage for clinicalimplementation.17 In addition, the intellectual property andpatent areas are awash with submissions for biomarker tests,often with little inventiveness, from groups having no clearintention of commercial test development.EVALUATION AND CLINICAL IMPLEMENTATIONTo date, the clinical evaluation of biomarkers rarely occurs.18Most of published studies have been underpowered andsingle-centre, with inherent bias. Only a few biomarkers areregularly used in clinical practice, and some of these havebeen problematical.19 Future biomarker studies will have to besufficiently powered, multi-institutional, and with prospectivevalidation.CRITICAL ISSUES IN BIOMARKER DEVELOPMENT FORCLINICAL TRIAL ENRICHMENTBiomarkers should first be selected based on biologicalplausibility, followed by validation. This begins bydemonstration of an association between the biomarker andthe clinical endpoint of interest, followed by independentstatistical validation of this association.20 For prognosticbiomarkers, statistical validation is relatively easy and can beundertaken through retrospective studies.21 However, sincepredictive biomarkers are used to identify patients likely tohave a favourable clinical outcome, validation may requirecomparing outcomes between biomarker-positive andbiomarker-negative patients.22 Randomised controlled trials(RCTs) are best suited for this purpose.23 New types of RCT arerequired to allow for the dynamic selection of patient subgroups, using biomarker-based therapies.24,25,26 These adaptiveclinical trials can speed up the drug development process bycollecting data from both biomarker positive and biomarkernegative patients.27 In particular, if the results suggest that thebenefits of a treatment are limited to the biomarker-positivesubpopulation, an enrichment design strategy in which onlybiomarker-positive patients are enrolled may be appropriate.27These new trial designs are still being developed, however itshould be noted that these designs do not provide informationon the effects of treatment in biomarker-negative patients.If there is some evidence to suggest that a biomarker canpredict that a therapy will be more effective in biomarkerpositive patients, but the evidence is not sufficient enoughto rule out clinical efficacy in biomarker-negative patients, abiomarker-stratified trial design may be more appropriate.28,29Here, biomarkers are used to guide analysis but not treatmentassignment. Biomarker-positive and negative patients arerandomly assigned to both treatment groups, providing betterevidence for the clinical utility of the biomarker. The FDA haspublished two draft guidance documents for industry on: (1)enrichment strategies; and (2) adaptive design clinical trials.30APPROACHES TO COLLABORATIVE CO-DEVELOPMENTA ‘companion diagnostic’ is a diagnostic test used as acompanion to a therapeutic drug to determine itsapplicability. Several operational and logistical challengesremain in their co-development with the therapeutic drug.31Ideally, they should be developed at the same time as thedrug so that clinical validation of the diagnostic can usedata from the development of the therapeutic. However,this is often problematic due to the different developmentalCancer Biomarkers In Australia9
models for diagnostics and therapeutics.32 Other challengesinclude uncertainty about the regulatory issues, weakfinancial incentives for investment, and clinical, logistical,and resource-related constraints.33 The FDA has publishedguidance documents and a concept paper for industry toaddress regulatory concerns.34 Co-development is increasing,yet the FDA has traditionally regulated these medicalproducts separately.35 Because of growth in this area, the FDAhas taken a number of steps to coordinate and clarify thereview process.In Australia, there is a longer mean time to PBS listing foroncology drugs that require a co-dependent application;approximately twice as long compared to oncology drugsthat do not require a co-dependent application.36 Very few codependent applications are given first time recommendationby both MSAC and PBAC. The average number of submissionsrequired for PBS listing of co-dependent oncologyapplications is well over two.There are examples where co-dependent applicationshave been delayed or not recommended in Australiabut are available in other jurisdictions with a comparablehealth technology assessment (HTA) process. For example,pembrolizumab was rejected in Australia for use in first andsecond line non-small cell lung cancer, but recommendedas having a clinical benefit in at least one of these patientgroups by HTA agencies in Germany, France, Canada and theUK. For co-dependent submissions, the average period fromregistration to reimbursement in Australia is, on average,much longer than in countries with similar HTA requirements(e.g., Canada, England and France).The key reasons for the delayed PBS listing of medicineswith a co-dependent technology in Australia have beenhighlighted in a case study submitted by Roche to the SenateInquiry into Funding for Research into Cancers with LowSurvival Rates.37 The case study on HER2 testing for use oftrastuzumab in gastric cancer highlighted that ‘delays andunpredictability are particularly common for targeted cancertherapies that use companion diagnostic tests’. Lengthydelays to PBS listing of trastuzumab were attributed to HTArejections, negative feedback from evaluators and challengesof allocating company resources to a complex submissionwith a low likelihood of success, requiring six HTA evaluations(three for the medicine and three for the test) to gainapproval. However, it should be noted that Australia, unlikesome other jurisdictions, requires evidence of both drugefficacy and cost-effectiveness before approval.10Cancer Biomarkers In AustraliaThe Europa-Bio report provided the followingrecommendations for health economic policy:38 Health economic evaluations need to become moreflexible and adapt to early launches based on highconfidence of therapeutic mechanism and earlypromising data. Relevant diagnosis of patients suitable for treatmentwith personalised medicines needs to become the normand embedded in routine healthcare pathways and thisshould not be viewed as an additional separate step andcost, brought about by having a new medicine available. More creative funding strategies, such as coverage withevidence development. Health decision-makers should set up systematicevaluations of personalised medicines based on theirlong-term cost-effectiveness.ACCELERATING THE USE OF BIOMARKERS ASSURROGATE ENDPOINTSIn oncology, a common endpoint is survival; clinical trialsseeking to evaluate the benefits of a drug on survival mayrequire many years before conclusions can be drawn.39Surrogate endpoints are biomarkers that are intended tosubstitute for the clinical endpoint, but can be measuredsooner or more conveniently and have the potential to reducethe length and cost of clinical trials. These could includeearlier endpoints such as progression-free survival. The FDAhas developed guidance intended to expedite the approvalof therapeutics (based on surrogate endpoints) that treatserious conditions where there is unmet need. A drug thatdemonstrates an effect on a surrogate endpoint reasonablylikely to predict clinical benefit may qualify for acceleratedapproval or breakthrough therapy designation.40For a biomarker to be conside
