Those capital costs reflect the returns that the funds could have earned if they had been invested in other ways. Each successive phase of clinical trials requires increasing amounts of spending. Companies will not necessarily cancel a drug project even if its likely future costs exceed its likely value when that assessment is made, because the expected value might rise with additional information about the drug or its market.
Pharmaceutical research is inherently risky and canceled or failed projects are a normal part of any drug development program. Companies initiate drug projects knowing that most of them will not yield a marketable drug. Some drugs developed in the preclinical phase never enter clinical trials, and of those that do, only about 12 percent reach the market recent estimates range from 10 percent to 14 percent.
Those estimates all include capital costs as well as expenditures on drugs that did not make it to market. The different estimates are averages over different samples of companies and drugs—that is, they depend on analytical and sampling choices made by the researchers producing those estimates and are best interpreted as illustrative of the general conclusion that developing new drugs is expensive and subject to high rates of failure.
Preclinical Phase. That is because companies typically develop many potential drugs in the preclinical phase that never enter or complete clinical trials. For drugs that do not reach the market, no return is realized, although lessons learned from those efforts may aid the development of other drugs. According to one study, the preclinical phase takes an average of about 31 months, followed by around 95 months, on average, for clinical trials—or about Clinical-Trials Phase.
The costs to conduct clinical trials on a drug are higher than those to conduct the preclinical phase because trials involve the contributions of many more people for a longer time. Clinical trials occur in several phases:. Generally, only drugs that have successfully navigated the first three phases can be considered for FDA approval, although regulators sometimes approve new drugs without a phase III trial. Of the 59 drugs approved in , 7 did not undergo phase III trials before approval.
Drug companies also might choose to conduct phase IV trials to show for marketing purposes the superiority of their product over other available drug therapies.
Few of the drugs that enter clinical trials are ultimately approved; some fail in clinical trials, and others are set aside when a company decides to focus on more promising drugs.
In a few cases, drugs submitted for approval are rejected by the FDA. In one sample of drugs in clinical trials, researchers found that for every drugs entering phase I trials, around 60 advanced to phase II trials, just over 20 entered phase III trials, and only about 12 gained FDA approval.
Costs tend to rise in each successive phase of development. In addition to the cost of preclinical research and clinical trials, drug companies incur costs by forgoing other opportunities for investment with money spent on clinical trials. Differences in sample selection and data sources appear to be important sources of variation in those estimates. The sample in that study consisted of 63 drugs developed by 47 different companies out of the drugs that the FDA approved between and The sample skews toward smaller firms—although the same is now true of drug development generally—and the authors caution that their sample may overrepresent drugs approved between and and those in certain therapeutic areas, first-in-class drugs, orphan drugs, and therapeutic agents that received accelerated approval.
In the third study, researchers limited their sample to new cancer drugs from companies with no previously approved products. Some evidence suggests that average success rates may indeed have declined. The study found that fewer than 12 percent of the drugs entering phase I clinical trials ultimately reached the market, but it reported success rates in excess of 20 percent for drugs developed in the s and s.
And, in some therapeutic classes, it has become more difficult to demonstrate that a new drug would improve on the existing standard of care.
As a result, clinical trials on potential cancer drugs have had to be expanded or extended so that the treatment effect on the lifespans of patients can be estimated with suitable precision. That is, because oncology treatments have become more effective, it now takes longer, on average, to observe a given number of deaths in a clinical trial. Policies in other countries and at other levels of government can also affect such spending.
Those policies are outside the scope of this report. Policies around federal health care programs and subsidies most directly affect the demand for new drugs. Still other areas of federal policymaking affect both supply and demand vaccine policies and regulatory policies. Policy changes in the opposite direction could make it a less appealing one. Federal Health Care Programs and Subsidies. A variety of federal health care programs and subsidies increase demand for health care services and products, including prescription drugs.
Taken together, federal and state expenditures on prescription drugs accounted for about 40 percent of total U. Those increases in current and anticipated revenues encouraged the industry to develop new drugs for the Medicare population.
Between and , the number of drugs entering phase I clinical trials increased by roughly 50 percent in therapeutic classes with relatively high sales to Medicare enrollees. That increased development activity eventually led to increases in the number of drugs in those classes. That stimulus would disappear if the tax subsidy on employment-based health insurance was eliminated. Support for Basic Research. The federal government is the primary funder of basic research in biomedical sciences.
That research ultimately increases the supply of new drugs because drug companies rely on the findings from that research—for example, the identification of disease targets toward which new drug therapies can be aimed. Basic research generates knowledge such as the identification of a disease target that is not readily embodied in a marketable product such as a drug. But because information can be communicated at low cost, it can be difficult to contain within a firm.
Private companies tend to be reluctant to conduct basic research such as identifying a new disease target, because it would be difficult to keep much of the value of that discovery for themselves. For example, once a disease target is known, multiple companies not just the company that identified it might be able to develop drugs aimed at that target. That weakens private incentives to invest in basic research and, as a result, private firms do too little of it from the perspective of society as a whole meaning that the social benefit if they performed additional basic research would be greater than the cost.
Since , NIH funding has increased annually. Indeed, most of the important new drugs introduced by the pharmaceutical industry over the past 60 years were developed with the aid of research conducted in the public sector. That relationship is complicated by two factors. The risk of crowding out is greater when the government funds research whose potential commercial applications are obvious and valuable, as was the case when federal and private research labs raced to map the human genome.
Second, federal research spending can also indirectly crowd out private spending by increasing the demand for skilled researchers. That could cause an increase in research labor costs in the private sector as well as in the public sector. Second, it allows all types of companies to deduct expenditures that are not eligible for the credits as business expenses in the year they are made. Tax Incentives. In addition, the Orphan Drug Act P. Effects of the Tax Act. The net effect of P.
The reduction in the top corporate tax rate will further reduce the value of the tax deduction. The tax act also reduced the tax credit created by the Orphan Drug Act from 50 percent to 25 percent of the cost of clinical trials. Costs applied to the tax credit for orphan drugs cannot also be applied to the research and experimentation credit, nor can they be deducted as expenses.
Policies Affecting Market Exclusivity. The federal government has adopted a variety of policies that grant periods of market exclusivity to manufacturers in order to increase the supply of new drugs. During those periods, the average prices for those new drugs are higher than they will be later, once lower-priced, generic versions are allowed to enter the market. That incentive is not unlimited: A manufacturer only receives market exclusivity over its own drug. The primary way that the federal government grants innovators temporary market exclusivity is through the U.
Most patents expire 20 years after the date on which the patent application was filed, but pharmaceutical companies can receive several additional years of patent protection in recognition that patented drugs cannot be sold until they complete clinical trials.
In recognition that a drug might spend several years of its market exclusivity in clinical trials, earning no revenue, the Hatch-Waxman Act P. Pharmaceutical companies can also receive additional exclusivity—distinct from that afforded by patents—for drugs that treat relatively uncommon diseases.
The Orphan Drug Act appears to have led to an increase in the number of new drugs for rare diseases. Policies Affecting Generic Drugs. In addition to extending the period of market exclusivity on brand-name drugs, the Hatch-Waxman Act enacted in also supports the development of generic drugs.
It extends drug patents by up to five years but encourages competition from generic drugs once the patents on a pioneering drug have expired. The legislation allows the FDA to approve most generic drugs without clinical trials. Instead, a manufacturer must show that its drug is pharmaceutically equivalent to the brand-name drug it copies, with the same active ingredients and no significant differences in the rate and extent of absorption at the site of drug action in the body.
The FDA only grants that additional exclusivity when the manufacturer has conducted clinical trials that the agency judges were essential. Thus, the act strengthened incentives to develop new drugs by extending drug patent life, and it made it easier for lower-cost generic versions to be introduced when the drugs enter the public domain by allowing the FDA to approve most generics based on pharmaceutical equivalence rather than clinical trials.
Policies Affecting Biosimilar Drugs. Congress has sought to provide inducement to the development of biosimilar drugs—the analog, for biologic drugs, of the generic copies of small-molecule drugs. So far, that legislation has resulted in relatively few approved biosimilar drugs compared to the effect that the Hatch-Waxman Act had on the development of generic drugs. As of December , the FDA had approved only 29 biosimilar drugs, and not all of them have been introduced.
The relative lack of competition for pioneering biologic drugs might contribute to the shift in new-drug development toward biologic drugs instead of small-molecule drugs.
In part, that shift might simply reflect advances in the underlying science. But biologic drugs are also attractive targets of research because they are harder to copy. The patent system does not require the original innovator to share the original cell line. Manufacturers seeking to make a biosimilar drug must develop their own living cell line to use as the basis for the new drug.
In addition, even under the abbreviated pathway specified by the FDA, biosimilar drugs must still be put through some clinical trials; unlike generic drugs, biosimilar drugs cannot avoid them altogether. Biologic drugs may face less competition than small- molecule drugs. Independent of but concurrent with patent protection, the FDA grants pioneering biologic drugs 12 years of guaranteed exclusivity in contrast to 5 years of exclusivity for small-molecule drugs.
However, certain federal payment policies and private contractual agreements may discourage the use of biosimilars. Vaccine Policies. Additionally, the Centers for Disease Control and Prevention publishes a schedule of recommended childhood and adult vaccinations, including specific recommendations for various groups, such as health care providers, travelers, expectant mothers, racial and ethnic populations, and people with certain underlying health conditions.
Those recommendations induce individuals to have themselves and their children vaccinated, and federal subsidies lower the costs to consumers of those vaccinations. A study that analyzed the effects of such policies found that the recommendation in that infants be vaccinated against hepatitis B and the expansion of Medicare coverage to include the cost of influenza vaccination in were both associated with subsequent increases in the development of new vaccines.
Federal policies also affect the supply of vaccines. The same study considered the federal Vaccine Injury Compensation Fund, which was established in to encourage manufacturers to develop and supply new vaccines by indemnifying the manufacturers against lawsuits arising from adverse reactions to childhood vaccines.
Regulatory Policies. Changes to regulation of clinical trials would also affect the supply of new drugs. Drug Prices. Drug companies can mostly set their own prices, although some federal agencies purchase drugs at prices subject to a statutory cap, impose statutory limits on how quickly a manufacturer can raise its prices, or receive rebates from manufacturers that are specified in statute.
In , the House of Representatives passed H. Under H. Those taxes would have had the same effect as if the drug had not been approved for sale or as if there were a formulary—that is, a national list of drugs that insurers could cover—from which the drug was excluded. Therefore, the potential use of the excise tax would have served as a source of pressure on drug manufacturers in negotiations and would have lowered drug prices and federal spending, CBO estimated.
More generally, state laws mandating or encouraging substitution of generic drugs for their brand-name equivalents help lower drug prices. The act also provides legal protections from claims of patent infringement to manufacturers who try to develop generic versions of a pioneering drug before its patents have expired and from liability for adverse events not listed on the label of the pioneering drug.
Clinical Trials. In particular, policymakers have made several changes to federal regulations governing clinical trials in an effort to reduce the time they take and therefore lower their cost. Surrogate endpoints include indirect, predictive indicators such as blood pressure, cholesterol level, tumor size, T-cell counts, or other physical signs of disease , along with other test results and laboratory measures.
The use of surrogate endpoints has helped neutralize a tendency in privately funded research to emphasize treatments that can be commercialized more quickly, which can result in too little investment in clinically valuable treatments that would take longer to develop. The total includes only research funded by PhRMA member firms, including any contract research funded by those firms and performed on their behalf by universities or other contract-research laboratories.
Unobserved rebates are paid by manufacturers to insurers or buyers and are considered proprietary information. April , p. See Qi Sun and Mindy Z. Hall and Nathan Rosenberg, eds.

In the Hatch-Waxman Act, those provisions are balanced by the provision of stronger patent protections to drug innovators, including extension of the statutory period of patent protection by a portion of the time the drug is under FDA review, and five years of ensured market exclusivity before the FDA may approve the first generic copy of a pioneering drug.
