How Can We Decide If a Biomedical Advance Is Ethical?

"All fixed, fast-frozen relations, with their train of ancient and venerable prejudices and opinions, are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned…"
On July 25, 1978, Louise Brown was born in Oldham, England, the first human born through in vitro fertilization, through the work of Patrick Steptoe, a gynecologist, and Robert Edwards, a physiologist. Her birth was greeted with strong (though not universal) expressions of ethical dismay. Yet in 2016, the latest year for which we have data, nearly two percent of the babies born in the United States – and around the same percentage throughout the developed world – were the result of IVF. Few, if any, think of these children as unnatural, monsters, or freaks or of their parents as anything other than fortunate.
How should we view Dr. He today, knowing that the world's eventual verdict on the ethics of biomedical technologies often changes?
On November 25, 2018, news broke that Chinese scientist, Dr. He Jiankui, claimed to have edited the genomes of embryos, two of whom had recently become the new babies, Lulu and Nana. The response was immediate and overwhelmingly negative.
Times change. So do views. How will Dr. He be viewed in 40 years? And, more importantly, how should we view him today, knowing that the world's eventual verdict on the ethics of biomedical technologies often changes? And when what biomedicine can do changes with vertiginous frequency?
How to determine what is and isn't ethical is above my pay grade. I'm a simple law professor – I can't claim any deeper insight into how to live a moral life than the millennia of religious leaders, philosophers, ethicists, and ordinary people trying to do the right thing. But I can point out some ways to think about these questions that may be helpful.
First, consider two different kinds of ethical commands. Some are quite specific – "thou shalt not kill," for example. Others are more general – two of them are "do unto others as you would have done to you" or "seek the greatest good for the greatest number."
Biomedicine in the last two centuries has often surprised us with new possibilities, situations that cultures, religions, and bodies of ethical thought had not previously had to consider, from vaccination to anesthesia for women in labor to genome editing. Sometimes these possibilities will violate important and deeply accepted precepts for a group or a person. The rise of blood transfusions around World War I created new problems for Jehovah's Witnesses, who believe that the Bible prohibits ingesting blood. The 20th century developments of artificial insemination and IVF both ran afoul of Catholic doctrine prohibiting methods other than "traditional" marital intercourse for conceiving children. If you subscribe to an ethical or moral code that contains prohibitions that modern biomedicine violates, the issue for you is stark – adhere to those beliefs or renounce them.
If the harms seem to outweigh the benefits, it's easy to conclude "this is worrisome."
But many biomedical changes violate no clear moral teachings. Is it ethical or not to edit the DNA of embryos? Not surprisingly, the sacred texts of various religions – few of which were created after, at the latest, the early 19th century, say nothing specific about this. There may be hints, precedents, leanings that could argue one way or another, but no "commandments." In that case, I recommend, at least as a starting point, asking "what are the likely consequences of these actions?"
Will people be, on balance, harmed or helped by them? "Consequentialist" approaches, of various types, are a vast branch of ethical theories. Personally I find a completely consequentialist approach unacceptable – I could not accept, for example, torturing an innocent child even in order to save many lives. But, in the absence of a clear rule, looking at the consequences is a great place to start. If the harms seem to outweigh the benefits, it's easy to conclude "this is worrisome."
Let's use that starting place to look at a few bioethical issues. IVF, for example, once proven (relatively) safe seems to harm no one and to help many, notably the more than 8 million children worldwide born through IVF since 1978 – and their 16 million parents. On the other hand, giving unknowing, and unconsenting, intellectually disabled children hepatitis A harmed them, for an uncertain gain for science. And freezing the heads of the dead seems unlikely to harm anyone alive (except financially) but it also seems almost certain not to benefit anyone. (Those frozen dead heads are not coming back to life.)
Now let's look at two different kinds of biomedical advances. Some are controversial just because they are new; others are controversial because they cut close to the bone – whether or not they violate pre-established ethical or moral norms, they clearly relate to them.
Consider anesthesia during childbirth. When first used, it was controversial. After all, said critics, in Genesis, the Bible says God told Eve, "I will greatly multiply Your pain in childbirth, In pain you will bring forth children." But it did not clearly prohibit pain relief and from the advent of ether on, anesthesia has been common, though not universal, in childbirth in western societies. The pre-existing ethical precepts were not clear and the consequences weighed heavily in favor of anesthesia. Similarly, vaccination seems to violate no deep moral principle. It was, and for some people, still is just strange, and unnatural. The same was true of IVF initially. Opposition to all of these has faded with time and familiarity. It has not disappeared – some people continue to find moral or philosophical problems with "unnatural" childbirth, vaccination, and IVF – but far fewer.
On the other hand, human embryonic stem cell research touches deeper issues. Human embryos are destroyed to make those stem cells. Reasonable people disagree on the moral status of the human embryo, and the moral weight of its destruction, but it does at least bring into play clear and broadly accepted moral precepts, such as "Thou shalt not kill." So, at the far side of an individual's time, does euthanasia. More exposure to, and familiarity with, these practices will not necessarily lead to broad acceptance as the objections involve more than novelty.
The first is "what would I do?" The second – what should my government, culture, religion allow or forbid?
Finally, all this ethical analysis must work at two levels. The first is "what would I do?" The second – what should my government, culture, religion allow or forbid? There are many things I would not do that I don't think should be banned – because I think other people may reasonably have different views from mine. I would not get cosmetic surgery, but I would not ban it – and will try not to think ill of those who choose it
So, how should we assess the ethics of new biomedical procedures when we know that society's views may change? More specifically, what should we think of He Jiankui's experiment with human babies?
First, look to see whether the procedure in question violates, at least fairly clearly, some rule in your ethical or moral code. If so, your choice may not be difficult. But if the procedure is unmentioned in your moral code, probably because it was inconceivable to the code's creators, examine the consequences of the act.
If the procedure is just novel, and not something that touches on important moral concerns, looking at the likely consequences may be enough for your ethical analysis –though it is always worth remembering that predicting consequences perfectly is impossible and predicting them well is never certain. If it does touch on morally significant issues, you need to think those issues through. The consequences may be important to your conclusions but they may not be determinative.
And, then, if you conclude that it is not ethical from your perspective, you need to take yet another step and consider whether it should be banned for people who do not share your perspective. Sometimes the answer will be yes – that psychopaths may not view murder as immoral does not mean we have to let them kill – but sometimes it will be no.
What does this say about He Jiankui's experiment? I have no qualms in condemning it, unequivocally. The potential risks to the babies grossly outweighed any benefits to them, and to science. And his secret work, against a near universal scientific consensus, privileged his own ethical conclusions without giving anyone else a vote, or even a voice.
But if, in ten or twenty years, genome editing of human embryos is shown to be safe (enough) and it is proposed to be used for good reasons – say, to relieve human suffering that could not be treated in other good ways – and with good consents from those directly involved as well as from the relevant society and government – my answer might well change. Yours may not. Bioethics is a process for approaching questions; it is not a set of universal answers.
This article opened with a quotation from the 1848 Communist Manifesto, referring to the dizzying pace of change from industrialization and modernity. You don't need to be a Marxist to appreciate that sentiment. Change – especially in the biosciences – keeps accelerating. How should we assess the ethics of new biotechnologies? The best we can, with what we know, at the time we inhabit. And, in the face of vast uncertainty, with humility.
Breakthrough therapies are breaking patients' banks. Key changes could improve access, experts say.
Single-treatment therapies are revolutionizing medicine. But insurers and patients wonder whether they can afford treatment and, if they can, whether the high costs are worthwhile.
CSL Behring’s new gene therapy for hemophilia, Hemgenix, costs $3.5 million for one treatment, but helps the body create substances that allow blood to clot. It appears to be a cure, eliminating the need for other treatments for many years at least.
Likewise, Novartis’s Kymriah mobilizes the body’s immune system to fight B-cell lymphoma, but at a cost $475,000. For patients who respond, it seems to offer years of life without the cancer progressing.
These single-treatment therapies are at the forefront of a new, bold era of medicine. Unfortunately, they also come with new, bold prices that leave insurers and patients wondering whether they can afford treatment and, if they can, whether the high costs are worthwhile.
“Most pharmaceutical leaders are there to improve and save people’s lives,” says Jeremy Levin, chairman and CEO of Ovid Therapeutics, and immediate past chairman of the Biotechnology Innovation Organization. If the therapeutics they develop are too expensive for payers to authorize, patients aren’t helped.
“The right to receive care and the right of pharmaceuticals developers to profit should never be at odds,” Levin stresses. And yet, sometimes they are.
Leigh Turner, executive director of the bioethics program, University of California, Irvine, notes this same tension between drug developers that are “seeking to maximize profits by charging as much as the market will bear for cell and gene therapy products and other medical interventions, and payers trying to control costs while also attempting to provide access to medical products with promising safety and efficacy profiles.”
Why Payers Balk
Health insurers can become skittish around extremely high prices, yet these therapies often accompany significant overall savings. For perspective, the estimated annual treatment cost for hemophilia exceeds $300,000. With Hemgenix, payers would break even after about 12 years.
But, in 12 years, will the patient still have that insurer? Therein lies the rub. U.S. payers, are used to a “pay-as-you-go” model, in which the lifetime costs of therapies typically are shared by multiple payers over many years, as patients change jobs. Single treatment therapeutics eliminate that cost-sharing ability.
"As long as formularies are based on profits to middlemen…Americans’ healthcare costs will continue to skyrocket,” says Patricia Goldsmith, the CEO of CancerCare.
“There is a phenomenally complex, bureaucratic reimbursement system that has grown, layer upon layer, during several decades,” Levin says. As medicine has innovated, payment systems haven’t kept up.
Therefore, biopharma companies begin working with insurance companies and their pharmacy benefit managers (PBMs), which act on an insurer’s behalf to decide which drugs to cover and by how much, early in the drug approval process. Their goal is to make sophisticated new drugs available while still earning a return on their investment.
New Payment Models
Pay-for-performance is one increasingly popular strategy, Turner says. “These models typically link payments to evidence generation and clinically significant outcomes.”
A biotech company called bluebird bio, for example, offers value-based pricing for Zynteglo, a $2.8 million possible cure for the rare blood disorder known as beta thalassaemia. It generally eliminates patients’ need for blood transfusions. The company is so sure it works that it will refund 80 percent of the cost of the therapy if patients need blood transfusions related to that condition within five years of being treated with Zynteglo.
In his February 2023 State of the Union speech, President Biden proposed three pilot programs to reduce drug costs. One of them, the Cell and Gene Therapy Access Model calls on the federal Centers for Medicare & Medicaid Services to establish outcomes-based agreements with manufacturers for certain cell and gene therapies.
A mortgage-style payment system is another, albeit rare, approach. Amortized payments spread the cost of treatments over decades, and let people change employers without losing their healthcare benefits.
Only about 14 percent of all drugs that enter clinical trials are approved by the FDA. Pharma companies, therefore, have an exigent need to earn a profit.
The new payment models that are being discussed aren’t solutions to high prices, says Bill Kramer, senior advisor for health policy at Purchaser Business Group on Health (PBGH), a nonprofit that seeks to lower health care costs. He points out that innovative pricing models, although well-intended, may distract from the real problem of high prices. They are attempts to “soften the blow. The best thing would be to charge a reasonable price to begin with,” he says.
Instead, he proposes making better use of research on cost and clinical effectiveness. The Institute for Clinical and Economic Review (ICER) conducts such research in the U.S., determining whether the benefits of specific drugs justify their proposed prices. ICER is an independent non-profit research institute. Its reports typically assess the degrees of improvement new therapies offer and suggest prices that would reflect that. “Publicizing that data is very important,” Kramer says. “Their results aren’t used to the extent they could and should be.” Pharmaceutical companies tend to price their therapies higher than ICER’s recommendations.
Drug Development Costs Soar
Drug developers have long pointed to the onerous costs of drug development as a reason for high prices.
A 2020 study found the average cost to bring a drug to market exceeded $1.1 billion, while other studies have estimated overall costs as high as $2.6 billion. The development timeframe is about 10 years. That’s because modern therapeutics target precise mechanisms to create better outcomes, but also have high failure rates. Only about 14 percent of all drugs that enter clinical trials are approved by the FDA. Pharma companies, therefore, have an exigent need to earn a profit.
Skewed Incentives Increase Costs
Pricing isn’t solely at the discretion of pharma companies, though. “What patients end up paying has much more to do with their PBMs than the actual price of the drug,” Patricia Goldsmith, CEO, CancerCare, says. Transparency is vital.
PBMs control patients’ access to therapies at three levels, through price negotiations, pricing tiers and pharmacy management.
When negotiating with drug manufacturers, Goldsmith says, “PBMs exchange a preferred spot on a formulary (the insurer’s or healthcare provider’s list of acceptable drugs) for cash-base rebates.” Unfortunately, 25 percent of the time, those rebates are not passed to insurers, according to the PBGH report.
Then, PBMs use pricing tiers to steer patients and physicians to certain drugs. For example, Kramer says, “Sometimes PBMs put a high-cost brand name drug in a preferred tier and a lower-cost competitor in a less preferred, higher-cost tier.” As the PBGH report elaborates, “(PBMs) are incentivized to include the highest-priced drugs…since both manufacturing rebates, as well as the administrative fees they charge…are calculated as a percentage of the drug’s price.
Finally, by steering patients to certain pharmacies, PBMs coordinate patients’ access to treatments, control patients’ out-of-pocket costs and receive management fees from the pharmacies.
Therefore, Goldsmith says, “As long as formularies are based on profits to middlemen…Americans’ healthcare costs will continue to skyrocket.”
Transparency into drug pricing will help curb costs, as will new payment strategies. What will make the most impact, however, may well be the development of a new reimbursement system designed to handle dramatic, breakthrough drugs. As Kramer says, “We need a better system to identify drugs that offer dramatic improvements in clinical care.”
In today's podcast episode, law professor Gaia Bernstein talks about the challenges of keeping control over our thoughts and actions, even when some powerful forces are pushing in the other direction.
Each afternoon, kids walk through my neighborhood, on their way back home from school, and almost all of them are walking alone, staring down at their phones. It's a troubling site. This daily parade of the zombie children just can’t bode well for the future.
That’s one reason I felt like Gaia Bernstein’s new book was talking directly to me. A law professor at Seton Hall, Gaia makes a strong argument that people are so addicted to tech at this point, we need some big, system level changes to social media platforms and other addictive technologies, instead of just blaming the individual and expecting them to fix these issues.
Gaia’s book is called Unwired: Gaining Control Over Addictive Technologies. It’s fascinating and I had a chance to talk with her about it for today’s podcast. At its heart, our conversation is really about how and whether we can maintain control over our thoughts and actions, even when some powerful forces are pushing in the other direction.

We discuss the idea that, in certain situations, maybe it's not reasonable to expect that we’ll be able to enjoy personal freedom and autonomy. We also talk about how to be a good parent when it sometimes seems like our kids prefer to be raised by their iPads; so-called educational video games that actually don’t have anything to do with education; the root causes of tech addictions for people of all ages; and what kinds of changes we should be supporting.
Gaia is Seton’s Hall’s Technology, Privacy and Policy Professor of Law, as well as Co-Director of the Institute for Privacy Protection, and Co-Director of the Gibbons Institute of Law Science and Technology. She’s the founding director of the Institute for Privacy Protection. She created and spearheaded the Institute’s nationally recognized Outreach Program, which educated parents and students about technology overuse and privacy.
Professor Bernstein's scholarship has been published in leading law reviews including the law reviews of Vanderbilt, Boston College, Boston University, and U.C. Davis. Her work has been selected to the Stanford-Yale Junior Faculty Forum and received extensive media coverage. Gaia joined Seton Hall's faculty in 2004. Before that, she was a fellow at the Engelberg Center of Innovation Law & Policy and at the Information Law Institute of the New York University School of Law. She holds a J.S.D. from the New York University School of Law, an LL.M. from Harvard Law School, and a J.D. from Boston University.
Gaia’s work on this topic is groundbreaking I hope you’ll listen to the conversation and then consider pre-ordering her new book. It comes out on March 28.
