How Are Drug Prices Determined?

By Todd Campbell and Kristine Harjes Markets Fool.com

A lot goes into getting a drug into a patient's hands, but the complexity of the distribution channel is only one reason why drug prices are high. As drugs get increasingly intricate, they're becoming more costly to develop, and that has an impact on prices, too. How can you determine if a drug price is fair?

Kristine Harjes:Welcome to Industry Focus, the podcast that dives into a different sector of the stock market every day. I'm your Healthcare show host, Kristine Harjes,and it's March 1. I'm in Alexandria, Virginia, at Fool HQ, and I have healthcare contributor Todd Campbell on the line. Todd,welcome to another week of Industry Focus!

Todd Campbell: Hi, Kristine! It's apleasure to be here.How are you today?

Harjes: Doing great,I'm excited for today's episode. Wewant to tackle a pretty important question,which is, why are prescription drugs so darn expensive? We will attempt toanswer that on this show. Then, after that,we wanted to give you somespecific, actionable advice that we think can improve all of our listeners'investing immediately. It should be a good one. Let's dive in. We'llstart with the drug question. Why are drugspriced the way they are? If you have been reading the newslately, you've seen headlines about price gouging and healthcare reform. This is a hot-button issue, and it affects the vast majority of our wallets directly. There's a lot ofpolitical attention beinggiven to it as well. We've had somelisteners write in, expressing concern about drug pricing and asking us questions, so we figured we would try to boil it down and have a conversation aboutwhat exactly goes into a drug price. What do you think, Todd?

Campbell: Kristine, I blame biologics.

Harjes: That's fair. For abackground, biologics are these big,complicated drugs. They'rerelatively new compared to the type of basic drug,which is a small-molecule drug. And since they'reso big and tricky, they're expensive, too.

Campbell: Yeah. Let's go back 20 years orwhatever, when we were just talking about small-molecule-chemicalproduced drugs. Those are relatively easily produced,easy to duplicate, and the rate ofinflation associated with drug prices 20years ago was much less than it is today.I really think that a lot of it has to do with thecomplexity that's associated with building out these new,next-generation therapies. They work better. But they'realso more complex to build. Andthere's a lot of failure that goes into developing drugs. When you combine thecomplexity plus the failure rates, you end up withhigher cost to produce, and those costsobviously getting translated into higher costs that payers have to pay.

Harjes: Right. So, that's themost obvious argument that you hearfrom drugmakers about their drug prices, "We need to recoup ourinvestment. We spent 10 years tryingto develop this drug,and not only that,but we also had years and years before thatof trying and failing on other drugs." It'svery expensive to run trials,and the majority of trials end up failingand are never commercialized at all.

Campbell: Right.I think investors have to remember, too, thatthis isn't a free market. It's a regulatory controlled marketbecause of patents. It's not like you're going out,you're developing this drug,and then you're competing instantaneously with 10 other peoplethat are going to drive down the price. No,you have a monopoly to recoup theexpense that you incurred over the course of that 10-year period. So,there's a lot of different things that are going into this. I think over the past couple years,you really saw the whole conversation blow up, if you will,because of these revelations thatpeople were going out and buying drugs that have been around for a while andjacking up the price 200% or 300%. Butit's not just those one-time price increases. It's much more systematic than that. You know, Kristine,that I like to put you on the spot.

Harjes: [laughs] Oh, boy,here we go.

Campbell: I'm going to put you and the listeners on the spot, here. Inresearching background for the show,I always turn toExpress Scripts(NASDAQ: ESRX) -- a pharmacy benefit manager -- and we'llget to that part in a minute. But every year, they put together a report that basicallydives into the nuts and bolts ofthe figures behind drug costs. Andone of the things they do, that I think is really interesting, Kristine, is back in 2008, theycreated a basket ofcommonly used brand-name drugs, and they set that basket at a base price of$100. They also decided to evaluate how that price changed over time, or, contrast it against a basket oftypical household goodsalso costing $100 back in 2008. Thequestion that I have for you, Kristine,and for the listeners, is to guess,how much do you think that $100basket of goods for the drugs now goes for? I'm going to give you a hint, or,something to compare it to. That's that thehousehold goods basket is $114.38 now. So, it went from $100 to $114.38. Any guess where we stand on that drug basket?

Harjes: Remind me of theinitial year where it was $100?

Campbell: 2008. So,2008 to now -- household basket has gone up around 14.4% over that whole period to $114.38.

Harjes: I would definitely guess it would be a lot more. I would say $180.

Campbell: $307.

Harjes: Oh my gosh!

Campbell: Yeah. 208% [sic] increase since 2008.I think that's really what's brought us to this breaking point where it's now become part of our common conversation. We had it overThanksgiving or Christmas, everyone's talking about drug prices, right?

Harjes: Yes,absolutely. But I think another part to that that'sreally important to mention, andI assume this is true of theExpress Scripts report, but that's list prices, yes?

Campbell: Correct, it's list prices. Andwhat's interesting is, there's a lot of players in how a drug getsproduced and delivered and put in your hand. There's all sorts of middle people.

Harjes: Right. When I say list price,I mean, that's what the company says is the sticker price. Butthat's not really what ends up getting paid. Like you said, there are all these middle men. You mentioned Express Scripts is a PBM, apharmacy benefits manager, that'ssomebody that negotiates between the payers and the drug makers for these prices. You have insurers trying to take a cut. So, you haveall of these different people that are getting in the way of it. There'sthe distributor whosends the drugs themselves to the pharmacy. Everybody needs to make their little bit of profit. So,there ends up being a prettysubstantial discount to that list price. Forexample, I was reading a report from IMS Health,which is a research firm. They say that even though list prices for drugs rose12% in 2015 alone, net prices grewonly 2.8%.

Campbell: Right. And that's backed up, Kristine, byExpress Scripts' report this year, which showed that last year, the list price on average climbed 10.7%. But after rebates anddiscounts, the net price was only up 2.5%. So, yeah, you're right, there'sa very big difference between that manufacturersuggested retail price --we're talking about cars here,whatever the true car value would be, maybe, of whatpeople are actually paying for it. But you're still talking about, over time, growth that issignificantly in excess of thetypical inflation measure,Consumer Price Index.

Harjes: Exactly. And while, on one hand,I think you could argue that these drugs are gettingbetter and better, so they're adding years to people's lives,so it's not really comparable tothe type of medicine that people were paying foryears ago, this is still a problem, and it's been a strain on a lot of people's pockets,particularly in the United States. Inthis country, the way that we do healthcare ispretty different from the rest of the world, and because of these elements andbecause the standard of living is so high, drug makers can effectively get away withthis kind of pricing.I think when you boil it all down, the drug makers are justtrying to figure out what they can get away with,how much money can they make for this drug, and that's the price they set. And often, that involves seeing what insurers are paying forcompeting drugs and evaluating how your new drugcompares to some of the existing oneson the market. Ultimately, it's kind of a repeating cycle, whereif you have expensive drug prices, and you have a small improvement on it, and you know that insurers are willing to pay X, and you have an even better drug, then you're going to add to that price.

Campbell: Right. Andthere's not a lot of price transparency. You have the list price,people know that. But the net discount,that's a trade secret.Gilead(NASDAQ: GILD)isn't going to tellAbbVie what it is that they'rewilling to discount their hepatitis C drug for. They'regoing to try to negotiate those deals the best they can witheach one of these participants. In the U.S., youtalked about globally, the U.S. is adifferent system. We don't give Medicare theability to go out and negotiate prices directly with drug makers. We have each one of these individual payers, so,UnitedHealth GrouporCignaorAetnaor whatever going out and sitting down and saying, "Give me your best price." Andof course, that's going to depend a lot on how many patients they represent. "If I can get anexclusivity deal,maybe I give them a better discount," or, "IfI can't get an exclusivity deal,maybe I don't give them as big a discount." Andthat's different thanother countries. For example,the United Kingdomwe like to talk about a lot,because that's probably the biggest difference between the two in the way that they approve drugs for useamong the patient populationin relation to pricing.

Harjes: Yeah.I really do find their system absolutely fascinating. They have this concept in the EU that's calledquality-adjusted life years, QALYs. This is a concept thattries to put the value of a drug in terms of the quality of lifeachieved after taking the drug. So,essentially, if the drug adds a year to your lifeat complete, total health,100% quality, that's one QALY. Or, say, it adds two years to your life, but you're only at 50% of your well-being and your health --and I have no idea how you actually measure quality of life, but say it's half of a quality of life measurement -- that would be 0.5X2, which is, again, one QALY.

Campbell: Exactly. You go from zero being death,not muchquality of life there,up until the full one,and that would be living a perfectly normal, healthyhappy life. And you're right,you touched on probably one of the biggestdrawbacks or knocks againstusing QALY,which is the subjectivity. How do you determine between zero and one what that quality of life is? You canlook at statistics and say, "If this drug added one year in overall survival, I know that's one year." But then,you get subjective when you start asking people to self-report, "Would you trade five years at 0.05 health for two years at one health?" Those subjective measurements make QALY a little bit of a moving target. NICE, which is thewatchdog for the U.K. drug system, uses QALY as a leveraging tool. They can go out and say to the drug maker, "Listen, if I take the cost and divide it by the QALY," and say it's a $100,000 drug and it's one year of life at perfect health, that's $100,000 QALY, "That's too pricey for us. You're going to have to bring that down to $50,000 for us to approve it." So, for them, they use it as a negotiating tactic. It's much harder, obviously, as investorsto try to figure out, if we'regoing to try and determine,because we know there's so much price uncertainty, how are we going to figure out whether or not a drug is going to be approved in other markets? Or,how are we going to find outwhether or not that's a fair price to charge for a drug here in the U.S.? It's very hard for us as investors. We either eyeball it, and we say, "Other drugs are selling for this, and this one's a little bit safer,so maybe it gets a little bit of a premium," or we try and compute QALY on our own, which is impossible,because we can't go out and talk to thepeople who participated in the trials andfigure out just how much their quality of life improved. We can guess some estimates, and say, "Let's map it out at 0.5 and one," or whatever. But for investors,it makes for a lot of uncertainty and difficulty in valuing what these drugs could face.

Harjes: When yougo to try and figure out a peak sales estimate, that'sgot to be the hardest part of it, trying to nail downexactly what price not only that the drugmaker will set, but that they'll actually end up receiving both in the U.S. and abroad. Because bothsystems clearly are very complex.

Campbell: Right. You had talked earlier about the cost to develop these drugs. Do you know, Kristine, what the latest average cost was for a drug development that's cited?

Harjes: I believe it's $2.6 billion for a single drug.

Campbell: Yeah,in the last few years, I think it's gone from $1.4 billion over to over $2 billion,like you said. But again,you have to take all those things with a grain of salt. That's an average, that includes all of the failed trials, too. You could have a company that doesextremely well, it is very efficient, and they get one drug on the market, maybe it costs them a fraction,a couple hundred million dollars. You could assume that maybe the innovationover time will reduce the number of drug failures in clinical trials,because it will be determined earlier on that these will fail, and that they'llnever enter the clinical,and maybe that brings pricing down somehow. This is not going to go away. It'scertainly not an easy problem to solve, eitherfrom a policy standpoint or as investors,trying to figure outthe sweet spot forpricing for a particular drug that might get rolled out.

Harjes: Exactly. I know we're onlyscratching the surface of truly understanding thistangled web of the reimbursement models and drugmakers margins andeverything that makes drug prices as high as they are. But I also want to leave some time in the episode togive our listeners an investing strategy thatminimizes your riskand is actually very likely to increase your returnover a long period of time, whichkind of sounds like it's a miracle strategy. Butit's something pretty simple. It's called dollar-cost averaging. Todd,I'm going to toss it over to youto explain what exactly that is.

Campbell: This isprobably one of the most powerful ways of investing, and it's also one of the absolute simplest. All you have to do is say, "I'mgoing to commit toinvesting a specific amount of money every month forsome specific interval." Forexample,you could say, "I'mgoing to invest $100 a monthregardless of whether or not stocks rise or fall.$100 a month every monthfrom now until the end of time."

Harjes: Right.The whole point of this is,once you commit to that, and you'resetting a fixed dollar amount, you end up buying more shares ofwhatever the security is when prices are low, and fewer shares when prices are high. So,I'm going to run through an example ofhow exactly that works. Take a stock, we mentionedGilead Sciences earlier, we'll go with Gilead. Say Gilead is trading at $100 right now.[laughs] I wish. Anyway, you want to invest $30,000. That would give you 300 shares. Say, instead, you'reinterested in dollar-cost averaging into thatposition over three months. You still have your $30,000, and you're going to do $10,000 worth every month. Initially,Gilead is still trading at $100, so you buy 100 shares. Let's say next month, it's up to$110,so you buy another $10,000 worth and you wind up with 91 shares. Then, next month, it's down to $90, so that same $10,000 gets you 111 shares. Add that all up after those three months, and thedollar-cost averaging strategygives you 302 shares, which is two extra shareswhen you compare it to buying all at once $30,000 at $100. Andif you look at your cost basis on those shares,it's $99 instead of $100. That doesn't sound like a lot, butif you extend this example over a long periodof time, the difference is more pronounced. That's also something thatwe have academic studies confirming.

Campbell: But, Kristine,can't I just put it all to work at one point in time and make more money?

Harjes: That would be the buying in $30,000 worth at $100. You would have 300 shares, your cost basis would be $100. If you run throughthe math in my example it's just not as good of a strategy.

Campbell: Themajoradvantage of dollar-cost averaging that Kristine justbeautifully walked through is that it smooths out your risk in your return. It helps to reduce thevolatility in your returns. Now, there's no getting around the fact thatif you're in a skyrocketing market, say,for example, coming out of the Great Recession up through now, if you had timed itperfectly and bought in March 2009,you would have done better by putting all of the money to work all at once, because it's been a pretty straight line up. Butthe reality is that markets rise and they fall,and the vast majority of people, evensome of the most talented investors of our generation,recognize that trying to time the market is highly unlikely that you'regoing to be able to do that consistently over and over again.

Harjes: Exactly, andsomething that we talk a lot about, here at The Motley Fool, istaking the emotion out of your of investing. It'simportant thateven when the market is dipping and prices are low, you need to still make that keypurchase of those same dollar amount of shares at the low purchase point to make this equation work out.

Campbell: Right,because the emotional component of that -- "Themarket is too expensive, the market's going to go to zero." Assoon as you start adjusting or messing withhow much money you're going to put in or whatever, you run the risk ofshooting yourself in the foot on this strategy. Set it and forget it. You canadjust it up over time as you'remaking more money or whatever. But have a certain amount of money, go in, don't get too cute with it. Over time, studies have shown --as a matter of fact, I don't remember which firm did it,I just read it recently,I have to look it up, Kristine,but it's stuck in my head that, the study showed that people who sold in the Great Recession to try and protect themselves didn't get back into the market in time, and as a result, people who just held through the whole Great Recession are way ahead of these people who tried to market-time and reduce the risk byselling and trying to buy back in at a different time. Or,you could look at it a different way --Warren Buffett made a great bet wherehe basically said, nine years ago, "I think if you just buy passively managed low-cost index funds, it would outperform the best stock pickers out there,actively managed funds, hedge funds." Andsomeone took the other side of that bet, andsure enough, in his annual report to investors, hejust updated the results, and the passiveinvesting strategy has returned 7% compounded annually, where theactive investment has only returned 2.2%compounded annually.I think what that shows you is, if you just use a dollar-costaveraging type strategy andcontinue and commit to it, and don'ttry to get too cute with it, you'llprobably come out far better off than you would otherwise.

Harjes: Exactly. As you mentioned a little bit ago, you can set it and forget it. I imagine that most interfaces have this option.I personally useCapital Oneinvesting,which was formerly ShareBuilder.I know for a fact that they offer, actually, a smaller trade commission when you do this, if you set up aregularly scheduled trade. You can plug in, "I want to buy this dollaramount at this frequency at this time, and here's exactly what I want it to go to." When you were talking about the Buffett bet, Todd,it reminded me that we should probably hit onwhat exactly people should be putting their money into. We talk a lot aboutindividual stocks. But it's kind of tough to commit to buying, say, $1,000 of Gilead at regular intervals over the next indefinite time period,because then you should probably be keeping up indoing your own due diligence on Gileadevery single month. Butone really good way to employ this strategy without the stress of having to hand-pick stocks to employ it with is going with an ETF.

Campbell: Yeah, absolutely. Wetalk about this over and over on this show --diversification is very important,especially when you're talking about the healthcare sector. By using ETFs, you can getexposure to a lot of different stocks within specific subsets of healthcare. So, you can, for example, buy the XLV, which is a broader ETF of healthcare stocks. Or, if you want just biotech, you can buy the IBB,which is a portfolio comprising ofsome of the biggest biotech stocks. By focusing on these ETFs, which,typically, by the way, area little bit less expensive as far as management fees, you can avoid some of that risk you just alluded to of buying a stock where something changes dynamically over a course of a 10-year period, and you no longer want to beinvesting in that. Polaroid jumps to mind, as an example of that.

Harjes: Exactly. This is a strategy that clearly has a lot of upside to it. I do want to point out, I thinka lot of people listening to this show areactually already doing thismaybe without even knowing it in their 401(k)s. That'sessentially what your 401(k) is -- you'recommitting to a certain amount of money at a regular interval, and itinvests that money regardless of the marketconditions. So, give yourself a pat on the back if you're already dollar-cost averaging into your 401(k).

Campbell: Oh jeez, Kristine,that just reminded me of something else. If you're a listener out thereand you happen to have a 401(k) planand you're doing your dollar-cost averaging fromhaving the money invested every month out of your paycheck, a lot of these 401(k) plans are now offering auto-escalating features whereyou can go in and sit down and talk to your human resources department and have them increase yourcontribution by 1% or2% every year. That's a fantastic way toincrease the amount that you're dollar-cost averaging over time,theoretically, to build yourself aneven bigger nest egg for retirement.

Harjes: And I do find that when you do those types ofset-it-and-forget-it types of strategies, where it just automatically takes money from your paycheck and funnels it somewhere productive, you don'tmiss the money. You never see it,so you can't spend it.

Campbell: Right. Andif you're doing it automatically,even with the increases,you don't have to worry so much aboutbusting your budget,having to play catch-up andmaking these large contributionslater on in your working career totry and make up for the years that you didn't do as much earlier on. That's so important, because if investing becomes hard,and you have to choose betweenhow many groceries you can buy this week versus putting money into your retirement account, theretirement account just going to end up losing.

Harjes: Yep,absolutely. That is a fantastic strategy. Thank you for sharing that. Andthank you for being on the show in general today.

Campbell: It'smy pleasure to be here.

Harjes: Asalways, people on the program may have interestsin the stocks that they talk about,and The Motley Fool may have formal recommendations for or against them, so don't buy or sell stocks based solely on what you hear, regardless of whether you'redollar-cost averaging into them or not.
