Are Physicians Morally Obligated to Prescribe Experimental Therapies?

A doctor reassuring a patient.
The federal 'Right to Try' bill in the United States recently passed the House and requires Senate approval before it becomes law. The bill would provide patients access to experimental drugs and other products that have not received approval from the Food and Drug Administration (FDA), including stem cell treatments.
It's not enough to act on a hunch that it might work.
Most folks think this is a good thing, but several express concern over whether the law would truly help patients. Even if a company allows patients to access an experimental drug, an important question remains: Should a doctor prescribe it?
Before such a drug can be prescribed, the federal bill states that a physician must "certify" that the patient has exhausted all available treatments or does not meet the criteria for standard treatment. Even after determining eligibility, a physician needs to consider a few points first. It's not enough to act on a hunch that it might work. The concept of medical innovation could help doctors figure out if prescribing an experimental treatment is the right thing to do.
Medical innovation falls within the doctor's scope of practice. Based on their experience and sound scientific rationale, physicians can "innovate" and offer treatment tailored to a patient with the goal of improving health. This differs from the goal of clinical research, which is to produce generalizable knowledge, not necessarily to benefit patients. In medical specialties like surgery, many of the standard procedures were developed through medical innovation, not clinical trials. Under the 'Right to Try,' a physician could ethically prescribe an experimental therapy as medical innovation if the following conditions are met.
Medical innovation should follow similar ethical and scientific oversight as clinical research.
First, there must be sound scientific rationale, and evidence of safety and efficacy of the innovative treatment from preclinical (animal and lab) research or clinical (human) research. The 'Right to Try' bill permits access to experimental products only after safety is demonstrated from a phase 1 clinical trial. This initial testing, called "first in human," aims to determine safety and dosing of an experimental product on typically around 20 to 100 people who are healthy volunteers or have a condition. This way, a physician can be assured that there is some evidence indicating the product is safe.
Efficacy must be demonstrated in animal and lab preclinical studies in order to gain permission from the FDA to do a phase 1 trial in the first place. This way, a doctor can also be assured that sound scientific rationale exists indicating a potential benefit to the patient. Only through further phase 2 and 3 clinical trials on hundreds or more people would a doctor know with greater certainty that the therapy works, but this might take many more years.
A doctor should not completely rely on what others in the scientific community think about the experimental treatment and should have appropriate expertise. This includes knowledge about the disease, familiarity with treating such patients, and an understanding of how the experimental treatment works, including administering it.
Second, medical innovation should follow similar ethical and scientific oversight as clinical research. Physicians should write a protocol for administering the experimental therapy and have it reviewed by clinical, scientific, and ethics experts at their institution. A protocol would include all the information on how the doctor would provide the therapy to patients, including dosages, monitoring, what happens if there are side effects, and much more. The experts would examine various components of the plan, look at informed consent, and ensure a favorable benefit-to-risk ratio, among other aspects.
When weighing whether to prescribe an experimental treatment, doctors need to base this decision on sound science and relevant clinical experience, not on hope or desperation.
Third, doctors should properly inform their patients about the risks (including if the risks are unknown), possible benefits, and the details of the procedure to be undertaken, and they must obtain the patient's consent.
Fourth, physicians should thoroughly monitor and diligently document all aspects of the outcomes of the procedure, various clinical indicators, and adverse events. During the course of providing an experimental therapy, if harm to a patient occurs, the physician is obligated to alter the course of the treatment or stop it. Similarly, if evidence from an ongoing clinical trial shows that the experimental treatment might help some but not all patients, the doctor needs to modify the plan accordingly.
Fifth, upon completing the experimental treatment, physicians should publish their findings to share the knowledge. Note that medical innovation is not meant to replace clinical trials. The two can be complementary, and medical innovation can lead to the design of clinical trials to demonstrate safety and efficacy.
Other experts may not agree that it can be ethical for a physician to prescribe an unapproved drug. Such dissenters would claim that physicians should only prescribe medications when there is substantial scientific and clinical certainty that a product is safe and effective for patients. They are also likely to oppose most forms of medical innovation. Yet even after undergoing rigorous clinical trials, some approved products have been shown to be unsafe or ineffective and are removed from the market.
While it seems that more evidence is better, doctors need to be mindful that patients are suffering and some may never receive access to drugs still in the pipeline. Bound by the Hippocratic Oath – the main tenet being "do no harm" – doctors are obligated to prescribe therapies that will help their patients. When weighing whether to prescribe an experimental treatment, doctors need to base this decision on sound science and relevant clinical experience, not on hope or desperation. Given that patients who want to participate in the 'Right to Try' movement have exhausted all other options and their condition may be worsening, it would seem ethically appropriate for a physician to treat them with an experimental drug, as long as the criteria listed above are satisfied.

The upcoming vaccine is changing the way we look at treating one of the country’s deadliest cancers.
Last week, researchers at the University of Oxford announced that they have received funding to create a brand new way of preventing ovarian cancer: A vaccine. The vaccine, known as OvarianVax, will teach the immune system to recognize and destroy mutated cells—one of the earliest indicators of ovarian cancer.
Understanding Ovarian Cancer
Despite advancements in medical research and treatment protocols over the last few decades, ovarian cancer still poses a significant threat to women’s health. In the United States alone, more than 12,0000 women die of ovarian cancer each year, and only about half of women diagnosed with ovarian cancer survive five or more years past diagnosis. Unlike cervical cancer, there is no routine screening for ovarian cancer, so it often goes undetected until it has reached advanced stages. Additionally, the primary symptoms of ovarian cancer—frequent urination, bloating, loss of appetite, and abdominal pain—can often be mistaken for other non-cancerous conditions, delaying treatment.
An American woman has roughly a one percent chance of developing ovarian cancer throughout her lifetime. However, these odds increase significantly if she has inherited mutations in the BRCA1 or BRCA2 genes. Women who carry these mutations face a 46% lifetime risk for ovarian and breast cancers.
An Unlikely Solution
To address this escalating health concern, the organization Cancer Research UK has invested £600,000 over the next three years in research aimed at creating a vaccine, which would destroy cancerous cells before they have a chance to develop any further.
Researchers at the University of Oxford are at the forefront of this initiative. With funding from Cancer Research UK, scientists will use tissue samples from the ovaries and fallopian tubes of patients currently battling ovarian cancer. Using these samples, University of Oxford scientists will create a vaccine to recognize certain proteins on the surface of ovarian cancer cells known as tumor-associated antigens. The vaccine will then train that person’s immune system to recognize the cancer markers and destroy them.
The next step
Once developed, the vaccine will first be tested in patients with the disease, to see if their ovarian tumors will shrink or disappear. Then, the vaccine will be tested in women with the BRCA1 or BRCA2 mutations as well as women in the general population without genetic mutations, to see whether the vaccine can prevent the cancer altogether.
While the vaccine still has “a long way to go,” according to Professor Ahmed Ahmed, Director of Oxford University’s ovarian cancer cell laboratory, he is “optimistic” about the results.
“We need better strategies to prevent ovarian cancer,” said Ahmed in a press release from the University of Oxford. “Currently, women with BRCA1/2 mutations are offered surgery which prevents cancer but robs them of the chance to have children afterward.
Teaching the immune system to recognize the very early signs of cancer is a tough challenge. But we now have highly sophisticated tools which give us real insights into how the immune system recognizes ovarian cancer. OvarianVax could offer the solution.”
How sharing, hearing, and remembering positive stories can help shape our brains for the better
Across cultures and through millennia, human beings have always told stories. Whether it’s a group of boy scouts around a campfire sharing ghost stories or the paleolithic Cro-Magnons etching pictures of bison on cave walls, researchers believe that storytelling has been universal to human beings since the development of language.
But storytelling was more than just a way for our ancestors to pass the time. Researchers believe that storytelling served an important evolutionary purpose, helping humans learn empathy, share important information (such as where predators were or what berries were safe to eat), as well as strengthen social bonds. Quite literally, storytelling has made it possible for the human race to survive.
Today, neuroscientists are discovering that storytelling is just as important now as it was millions of years ago. Particularly in sharing positive stories, humans can more easily form relational bonds, develop a more flexible perspective, and actually grow new brain circuitry that helps us survive. Here’s how.
How sharing stories positively impacts the brain
When human beings share stories, it increases the levels of certain neurochemicals in the brain, neuroscientists have found. In a 2021 study published in Proceedings of the National Academy of Sciences (PNAS), Swedish researchers found that simply hearing a story could make hospitalized children feel better, compared to other hospitalized children who played a riddle game for the same amount of time. In their research, children in the intensive care unit who heard stories for just 30 minutes had higher levels of oxytocin, a hormone that promotes positive feelings and is linked to relaxation, trust, social connectedness, and overall psychological stability. Furthermore, the same children showed lower levels of cortisol, a hormone associated with stress. Afterward, the group of children who heard stories tended to describe their hospital experiences more positively, and even reported lower levels of pain.
Annie Brewster, MD, knows the positive effect of storytelling from personal experience. An assistant professor at Harvard Medical School and the author of The Healing Power of Storytelling: Using Personal Narrative to Navigate Illness, Trauma, and Loss, Brewster started sharing her personal experience with chronic illness after being diagnosed with multiple sclerosis in 2001. In doing so, Brewster says it has enabled her to accept her diagnosis and integrate it into her identity. Brewster believes so much in the power of hearing and sharing stories that in 2013 she founded Health Story Collaborative, a forum for others to share their mental and physical health challenges.“I wanted to hear stories of people who had found ways to move forward in positive ways, in spite of health challenges,” Brewster said. In doing so, Brewster believes people with chronic conditions can “move closer to self-acceptance and self-love.”
While hearing and sharing positive stories has been shown to increase oxytocin and other “feel good” chemicals, simply remembering a positive story has an effect on our brains as well. Mark Hoelterhoff, PhD, a lecturer in clinical psychology at the University of Edinburgh, recalling and “savoring” a positive story, thought, or feedback “begins to create new brain circuitry—a new neural network that’s geared toward looking for the positive,” he says. Over time, other research shows, savoring positive stories or thoughts can literally change the shape of your brain, hard-wiring someone to see things in a more positive light.How stories can change your behavior
In 2009, Paul Zak, PhD, a neuroscientist and professor at Claremont Graduate University, set out to measure how storytelling can actually change human behavior for the better. In his study, Zak wanted to measure the behavioral effects of oxytocin, and did this by showing test subjects two short video clips designed to elicit an emotional response.
In the first video they showed the study participants, a father spoke to the camera about his two-year-old son, Ben, who had been diagnosed with terminal brain cancer. The father told the audience that he struggled to connect with and enjoy Ben, as Ben had only a few months left to live. In the end, the father finds the strength to stay emotionally connected to his son until he dies.
The second video clip, however, was much less emotional. In that clip, the same father and son are shown spending the day at the zoo. Ben is only suggested to have cancer (he is bald from chemotherapy and referred to as a ‘miracle’, but the cancer isn’t mentioned directly). The second story lacked the dramatic narrative arc of the first video.
Zak’s team took blood before and after the participants watched one of the two videos and found that the first story increased the viewers’ cortisol and oxytocin, suggesting that they felt distress over the boy’s diagnosis and empathy toward the boy and his father. The second narrative, however, didn’t increase oxytocin or cortisol at all.
But Zak took the experiment a step further. After the movie clips, his team gave the study participants a chance to share money with a stranger in the lab. The participants who had an increase in cortisol and oxytocin were more likely to donate money generously. The participants who had increased cortisol and oxytocin were also more likely to donate money to a charity that works with children who are ill. Zak also found that the amount of oxytocin that was released was correlated with how much money people felt comfortable giving—in other words, the more oxytocin that was released, the more generous they felt, and the more money they donated.
How storytelling strengthens our bond with others
Sharing, hearing, and remembering stories can be a powerful tool for social change–not only in the way it changes our brain and our behavior, but also because it can positively affect our relationships with other people
Emotional stimulation from telling stories, writes Zak, is the foundation for empathy, and empathy strengthens our relationships with other people. “By knowing someone’s story—where they come from, what they do, and who you might know in common—relationships with strangers are formed.”
But why are these relationships important for humanity? Because human beings can use storytelling to build empathy and form relationships, it enables them to “engage in the kinds of large-scale cooperation that builds massive bridges and sends humans into space,” says Zak.
Storytelling, Zak found, and the oxytocin release that follows, also makes people more sensitive to social cues. This sensitivity not only motivates us to form relationships, but also to engage with other people and offer help, particularly if the other person seems to need help.
But as Zak found in his experiments, the type of storytelling matters when it comes to affecting relationships. Where Zak found that storytelling with a dramatic arc helps release oxytocin and cortisol, enabling people to feel more empathic and generous, other researchers have found that sharing happy stories allows for greater closeness between individuals and speakers. A group of Chinese researchers found that, compared to emotionally-neutral stories, happy stories were more “emotionally contagious.” Test subjects who heard happy stories had greater activation in certain areas of their brains, experienced more significant, positive changes in their mood, and felt a greater sense of closeness between themselves and the speaker.
“This finding suggests that when individuals are happy, they become less self-focused and then feel more intimate with others,” the authors of the study wrote. “Therefore, sharing happiness could strengthen interpersonal bonding.” The researchers went on to say that this could lead to developing better social networks, receiving more social support, and leading more successful social lives.
Since the start of the COVID pandemic, social isolation, loneliness, and resulting mental health issues have only gotten worse. In light of this, it’s safe to say that hearing, sharing, and remembering stories isn’t just something we can do for entertainment. Storytelling has always been central to the human experience, and now more than ever it’s become something crucial for our survival.
