Biopharmaceutical research companiesare developing 215 medicines for twoof the leading causes of death in Amer-icans—heart disease and stroke. Thesetherapies promise to build on the prog-ress made by existing treatments, whichhave helped cut deaths from heart dis-ease by a third between 2001 and 2011,according to the Centers for DiseaseControl and Prevention (CDC).According to the CDC’s National Centerfor Health Statistics, heart disease hastopped the list of deadly diseases everyyear since 1921. Thanks in large partto new drug treatments, death ratesfrom heart disease and stroke are falling.In 2008, stroke dropped to the fourthleading cause of death after being thethird for more than 50 years. Much ofthe progress is due to the developmentof effective medicines to control bothblood pressure and cholesterol, accordingto the National Heart, Lung and BloodInstitute (NHLBI).Despite this progress, heart disease andstroke persist as key public health chal-lenges. According to the American HeartAssociation, every 39 seconds an Ameri-can dies from cardiovascular disease, andmore than 83 million Americans haveat least one form of the disease. Manypeople who survive heart attacks stilldevelop heart failure, a chronic diseasethat affects 5.7 million Americans. Thesediseases cost society more than $312billion a year.The medicines in development include:30 for heart failure, 29 for lipid disorders(such as high cholesterol), 19 for strokeand 17 each for high blood pressure andischemic disorders. Many of the potentialmedicines use cutting-edge technologiesand new scientific approaches, such as:• A gene therapy that uses a patient’sown cells to treat heart failure.• A medicine that blocks the transfer ofgood (HDL) cholesterol to bad (LDL).• A genetically-engineered medicine thatdissolves clots to treat stroke.These new medicines—all in eitherhuman clinical trials or awaiting reviewby the Food and Drug Administration—promise to continue the already remark-able progress against heart disease andstroke and to raise the quality of life forpatients suffering from these diseases.This overview highlights some of theinnovative medicines listed in the report,recent scientific advances in treatingcardiovascular disease, and the value ofmedicines for patients and our healthcaresystem.More Than 200 Medicines in Development forCardiovascular Disease—Leading Cause of Death inthe United States2013REPORTLipidDisordersHypertension3017 17IschemicDisorders29HeartFailureStroke19ApplicationSubmittedPhase IIIPhase IIPhase IMedicines in DevelopmentFor Heart Disease and StrokeMedicines in DevelopmentHeart Disease and StrokeA Report on Cardiovascular Diseasepresented by america’s biopharmaceutical research companies

2 OVERVIEW • Medicines in Development Heart and StrokeInnovative Medicines in the PipelineLong-term Treatment for Chronic Heart Disease—Ath-erosclerosis, an inflammatory disease characterized by thebuilding-up of plaque within the walls of the arteries, is theunderlying cause of most heart attacks and strokes. Onenovel medicine is a selective inhibitor of an enzyme found inblood and atherosclerotic plaque, Lp-PLA2. Elevated levels ofthe enzyme are involved in the development and progressionof atherosclerosis.Stem Cell Therapy—A potential treatment for ischemic heartfailure uses adult stem cells to target damaged tissue in theheart. The cells are inserted using an investigational catheterthat enables local delivery of cell and gene therapies.Lowering Blood Lipids—A potential medicine in developmentis a selective inhibitor of a protein that plays a major rolein transferring high-density cholesterol lipoprotein (HDL, orgood cholesterol) to low-density lipoprotein cholesterol (LDL,or bad cholesterol). High HDL levels can help decrease therisk of cardiovascular disease. The CDC estimates that a 10percent decrease in total cholesterol levels population-widecould result in a 30 percent reduction in the incidence ofcoronary artery disease.Gene Therapy for Heart Failure—A genetically-targeted en-zyme replacement therapy for congestive heart failure is beingtested to restore levels of a specific gene to promote a failingheart to pump better and minimize the severity of heart fail-ure. In all forms of late-stage heart failure, levels of the genedecline resulting in deficient heart function.Recombinant Fibrin for Stroke—A genetically-engineeredclot-dissolving protein derived from the saliva of the vampirebat, Desmodus rotundus, is being developed for the treat-ment of ischemic stroke. The protein—fibrin-specific plasmin-ogen activator—is structurally similar to human tissue-typeplasminogen activator (tPA)—a medicine approved to treatstroke. TPA treatment must take place within three hoursfrom when a stroke takes place. About 80 percent of strokesare not diagnosed until after three hours. The potential med-icine is being tested to lengthen the treatment window up tonine hours.12129101283015179172914191320Heart AttackHeart FailureCoronary Artery DiseaseAdjunctive TherapiesAtherosclerosisArrhythmiaAcute Coronary SyndromePulmonary Vascular DiseaseStrokeThrombosisOtherPeripheral Vascular DiseaseImaging AgentsLipid DisordersIschemic DisordersHypertensionApplicationSubmittedPhase IIIPhase IIPhase IMedicines in Development for Cardiovascular Disease By Type and Phase of DevelopmentSome medicines are listed in more than one category

32013 ReportTreatment Advances—Lives Saved,Costs Reduced, Improved TreatmentsIn the late 1950s, cardiovascular deaths were on the rise anddoctors had few tools to treat their patients. Today, doctorshave many new ways to treat cardiovascular disease. Thesenew tools have helped reduce the number of deaths sincethe 1960s.Advances in medicine helped cut deaths from heart diseaseby 30 percent between 2001 and 2011, according to theCDC. The CDC said the factors contributing to the ongoingdecline are better control of risk factors, early detection, andbetter treatment and care, including new drugs and expandeduse of existing drugs.Progress against cardiovascular disease has had a profoundimpact on helping to control health care costs. According toa study published in Health Affairs, every additional dollarspent on medicines for adherent patients with congestiveheart failure, high blood pressure, diabetes and high choles-terol generated $3 to $10 dollars in savings on emergencyroom visits and inpatient hospitalizations.Atrial Fibrillation and Stroke RiskPatients with atrial fibrillation (AFib)—the most commonform of arrhythmia—are five times more at risk for a strokethan people without AFib. For more than 50 years, patientswith AFib have relied on the anticoagulant warfarin to thintheir blood and reduce their risk of a stroke. The use ofwarfarin requires frequent blood monitoring, dosage adjust-ments and food restrictions. Two new medicines approvedfor the reduction of the risk of stroke and blood clots inpatients with AFib, do not require frequent blood monitor-ing, dosage adjustments or food restrictions. While the newdrugs use different mechanisms of action—both have aneasy treatment regimen—with one or two dosages daily.Lipid Disorders—High CholesterolThe CDC reported in 2007 that U.S. adults reached anaverage cholesterol level in the ideal range (below 200) forthe first time in 50 years. Authors of the report attribute thedrop to the increased use of cholesterol-lowering medicines inthe over-60 population. Also, research has shown that statintherapy reduces low-density lipoprotein cholesterol levels byFRAMINGHAM HEART STUDYIn 1961, a huge milestone in cardiovascular researchwas achieved: data from the Framingham HeartStudy, a joint project between the National Heart,Lung and Blood Institute and Boston University,definitively revealed a link between high bloodcholesterol levels and heart disease. These findingshelped focus research that led to new medicines.Following subsequent public/private research andpublished studies, the development and launch ofthe first statin in the U.S. occurred in 1987 resultingin better control of cholesterol levels among U.S.adults, and falling death rates from cardiovasculardisease.Death rates from cardiovascular disease declinedmore than 30% from 1998 to 2008, the AmericanHeart Association recently reported. A 2007 study inJAMA showed that between 1999 and 2005, deathrates for heart failure and heart attack decreasedby nearly half—thanks to greater use of cholesterolmedicines, blood thinners and angioplasty.While there were many research milestonesthat led to a better understanding of the role ofcholesterol and the eventual discovery of statins, theFramingham Heart Study’s pioneering work was apivotal moment.

4 OVERVIEW • Medicines in Development Heart and Strokean average of 19 percent. Over one year, this reduction inbad cholesterol was associated with roughly 40,000 fewerdeaths, 60,000 fewer hospitalizations for heart attacks, and22,000 fewer hospitalizations for strokes in the U.S. From aneconomic perspective, those prevented hospitalizations trans-lated into gross savings of nearly $5 billion.Congestive Heart FailurePatients with CHF are among the most expensive to treatin the entire health care system. Several studies have foundkey savings: hospitalizations, surgeries, and ER use are all keydrivers of the high costs of CHF, with hospitalizations for atypical CHF patient costing up to $21,868 (in 2010 USD).Consistent use of medicines, however, which might cost$3,468 per year (in 2010 USD), can prevent complicationsand slow the progression of the disease. Patients who taketheir medications as prescribed can reduce their healthcarecosts by up to $9,161 (in 2010 USD) compared to patientswho do not take their medication as recommended by theirdoctor. Certain medications have been shown to improvesymptoms and decrease hospital readmission rates. In ad-dition, if used early, these medicines also play an importantrole in preventing CHF from developing in the first place.Medication therapy leading to well controlled hypertension,for example, can reduce the risk of CHF by 40 percent to50 percent, potentially leading to even greater savings.Hypertension—High Blood PressureAccording to a study published in Health Affairs, treatingpatients with high blood pressure in accordance with clinicalguidelines would result in fewer strokes and heart attacks,preventing up to 89,000 deaths and 420,000 hospitalizationsannually and saving $15.6 billion a year.Growing New Heart MuscleTwo studies published in Nature, showed that a new ap-proach called myogenesis (growing new heart muscle) showspromise in replacing damaged or lost heart muscle after aheart attack. These studies revealed that by reprogrammingnon-beating heart muscle cells (non-cardiomyocytes) intobeating heart muscle cells (cardiomyocytes) could replacedamaged heart cells and repair scarring.Results of two human trials using different types of cardiaccells showed that cells from heart biopsies could be purifiedand replaced into the patient’s own heart, improving heartfunction and reducing scarring. The studies were published inThe Lancet.CARDIOVASCULAR DISEASE RISK FACTORSStudies published last year, found lifestyle factorshave a huge impact on lowering the risk of heartdisease and stroke, and in helping people extendtheir lives. People with “ideal cardiovascular health,”measured by health behaviors (not smoking, regularexercise and healthy diet) and health factors (idealbody mass index, cholesterol, blood pressure andblood glucose) had the lowest risk.Even with adequate cardiac care, prevention is stillthe most important factor in reducing cardiovasculardisease. Major risk factors include:• Family history and genetics• Smoking• High Blood Cholesterol and Other Lipids• Physical Inactivity• Overweight/Obesity• Diabetes

52013 ReportMedicare Part D Providing EconomicValue and Improved AdherenceThe American Heart Association estimates that heart failure(congestive heart failure) costs will double in the next 20years as prevalence rates rise and the U.S. population ages.By 2030, direct and indirect costs to treat heart failure couldmore than double from $31 billion in 2012 to $70 billion in2030. And, the number of people with heart failure couldincrease by 46 percent from 5 million in 2012 to 8 millionin 2030.As the prevalence and cost of heart failure is rising, a newstudy supported by PhRMA and published in The AmericanJournal of Managed Care, found that improved adherenceto medication following the expansion of drug coverageunder Medicare Part D, led to nearly $2.6 billion in savingsin medical expenditures annually among beneficiaries withcongestive heart failure (CHF). Despite the improvements inadherence following Part D, medication use remainssub-optimal. The study also found that improving adherenceto recommended levels could save Medicare another$1.9 billion annually, leading to $22.4 billion over 10 years.A recent report by the Congressional Budget Office (CBO)explicitly recognized the beneficial impact prescription med-icines have on reducing other health care spending. Specifi-cally, the CBO changed its scoring methodology to reflectsavings in medical spending associated with policies thatincreased use of medicines in Medicare. Savings estimatesmay even be conservative and underestimate the magnitudeof effect for many beneficiaries with chronic conditions, forwhom cost offsets are likely to be greater and more sensitiveto drug use than the broader population.“Improving medicine adherence torecommended levels could saveMedicare another $1.9 billion annually,leading to $22.4 billion over 10 years.”83.6MillionAmericans SufferFrom CardiovascularDiseaseMore Than700,000Die Each Year

6 OVERVIEW • Medicines in Development Heart and StrokeFacts About Heart Disease and Stroke in the United States• Approximately 83.6 million American adults—greater than one in three—have one or more types of CVD. Of that total,42.2 million are estimated to be age 60 and older.1• On average, 2,150 Americans die of CVD each day, about one death every 40 seconds. CVD claims more lives each yearthan cancer and chronic lower respiratory diseases combined.1• In 2010, CVD accounted for 727,165 of all 2,468,435 deaths from all causes—29.5 percent.2• The estimated direct and indirect costs of CVD were $312.6 billion in 2009.1Atherosclerosis2Cardiovascular Diseases (CVD)• Atherosclerosis of the coronary arteries is the leading cause of death for both men and women in the United States. Inmen, the risk increases after age 45; in women, the risk increases after age 55.• In 2009, atherosclerosis accounted for 7,377 deaths.Major Cardiovascular Diseases1Condition Prevalence DeathsAngina Pectoris 7.8 million n/aAtrial Fibrillation 2.7 million – 6.1 million 15,434Coronary Heart Disease 15.4 million 386,324Heart Attack (Myocardial Infarction) 7.6 million 125,464Heart Failure 5.1 million 56,410Hypertension 77.9 million 61,672Stroke 6.8 million 128,842

Heart Disease and Stroke Statistics—2010 Update, American Heart Association, www.heart.org 2. National Heart, Lung and Blood Institute, www.nhlbi.nih.gov• On average, someone in this country has a stroke every 40 seconds. An estimated 6.8 million Americans have suffered astroke, and each year about 795,000 people experience a new or recurrent stroke.• On average, someone dies from a stroke every four minutes in the United States.• Eighty-seven percent of all strokes are ischemic, 10 percent are intracerebral and 3 percent are subarachnoid hemorrhage.• Each year, an estimated 915,000 new and recurrent cases of CHD and 715,000 new and recurrent cases of myocardialinfraction occur.• There are 500,000 new cases of stable angina each year.

Pharmaceutical Research and Manufacturers of America950 F Street, NW, Washington, DC 20004www.phrma.orgThe U.S. system of new drug approvals isperhaps the most rigorous in the world.It takes 10-15 years, on average, for an experi-mental drug to travel from lab to U.S. patients,according to the Tufts Center for the Study ofDrug Development. Only five in 5,000 com-pounds that enter preclinical testing make it tohuman testing. And only one of those five isapproved for sale.On average, it costs a company $1.2 billion,including the cost of failures, to get one newmedicine from the laboratory to U.S. patients,according to a recent study by the Tufts Centerfor the Study of Drug Development.Once a new compound has been identified inthe laboratory, medicines are usually developedas follows:Preclinical Testing. A pharmaceutical companyconducts laboratory and animal studies to showbiological activity of the compound against thetargeted disease, and the compound is evaluat-ed for safety.Investigational New Drug Application (IND).After completing preclinical testing, a compa-ny files an IND with the U.S. Food and DrugAdministration (FDA) to begin to test the drugin people. The IND shows results of previousexperiments; how, where and by whom the newstudies will be conducted; the chemical structureof the compound; how it is thought to work inthe body; any toxic effects found in the animalstudies; and how the compound is manufac-tured. All clinical trials must be reviewed and ap-proved by the Institutional Review Board (IRB)where the trials will be conducted. Progressreports on clinical trials must be submitted atleast annually to FDA and the IRB.Clinical Trials, Phase I—Researchers test thedrug in a small group of people, usually between20 and 80 healthy adult volunteers, to evaluateits initial safety and tolerability profile, deter-mine a safe dosage range, and identify potentialside effects.Clinical Trials, Phase II—The drug is givento volunteer patients, usually between 100 and300, to see if it is effective, identify an optimaldose, and to further evaluate its short-termsafety.Clinical Trials, Phase III—The drug is given to alarger, more diverse patient population, ofteninvolving between 1,000 and 3,000 patients(but sometime many more thousands), togenerate statistically significant evidence toconfirm its safety and effectiveness. They arethe longest studies, and usually take place inmultiple sites around the world.New Drug Application (NDA)/Biologic LicenseApplication (BLA). Following the completionof all three phases of clinical trials, a companyanalyzes all of the data and files an NDA or BLAwith FDA if the data successfully demonstrateboth safety and effectiveness. The applicationscontain all of the scientific information that thecompany has gathered. Applications typicallyrun 100,000 pages or more.Approval. Once FDA approves an NDA or BLA,the new medicine becomes available for physi-cians to prescribe. A company must continue tosubmit periodic reports to FDA, including anycases of adverse reactions and appropriate qual-ity-control records. For some medicines, FDArequires additional trials (Phase IV) to evaluatelong-term effects.Discovering and developing safe and effectivenew medicines is a long, difficult, and expensiveprocess. PhRMA member companies invested anestimated $48.5 billion in research and develop-ment in 2012.Developing a new medicine takes an average of 10-15 years;For every 5,000-10,000 compounds in the pipeline, only 1 is approved.The Drug Development and Approval ProcessPRE-DISCOVERYDRUG DISCOVERY PRECLINICAL CLINICAL TRIALS FDA REVIEW LG-SCALE MFG3 – 6 YEARS 6– 7 YEARS0.5– 2YEARS100–300 1,000–3,00020–80PHASE2PHASE3PHASE1INDSUBMITTEDNDASUBMITTEDPHASE4:POST-MARKETINGSURVEILLANCENUMBER OF VOLUNTEERSONE FDA-APPROVEDDRUG5,000 –10,000COMPOUNDS250 5Drug Discovery and Development: A LONG, RISKY ROAD
