  • Is it still safe to drive? Have the doctor request a driving test

    Is it still safe to drive? Have the doctor request a driving test

    If you are lucky enough to live to a ripe old age, there may come a time when you should stop driving, both for your own safety and the safety of others. You may no longer have the reflexes, the hearing, the vision, or the overall ability to react quickly to a challenging situation on the road. Is it still safe to drive or time to put away the car keys? With the doctor’s help, get a driving test.

    My dad was still driving, and driving very cautiously, at the age of 91. He was only driving during the day, on local roads with relatively little traffic, at low speed limits. And, he loved the freedom driving offered him to get out and about. So, it was extremely hard for me to decide what to do.

    Different people offered me different advice. Some suggested I simply take away his keys, which I was unprepared to do. My dad showed no signs of being a danger on the road. And, I do not believe it was my place to make the decision for him. His doctor, likewise, was not prepared to say he should not drive.

    I broached the topic with my dad, a highly responsible man. And, he saw no reason to stop driving. He was super careful. He did not feel stressed or anxious about driving. And, being able to drive gave him much valued independence. It allowed him to get to the grocery store, the pharmacy and his water aerobics class, all important destinations for him.

    I respected my father’s position, but I also worried for his safety and the safety of others. I then learned that the registry of motor vehicles (RMV) gave “competency” tests to older people to determine whether they were still fit to drive. That seemed like a good idea to me, but my father was resistant. He did not see the need. And, the RMV would not require it on its own.

    So, I spoke to my dad’s doctor. She offered to send a letter to the registry of motor vehicles requesting he take the competency test. On his doctor’s request, the RMV would schedule it. And, shortly thereafter, the RMV called my dad in.

    His driver’s license was revoked before he had taken the road test. My dad failed the vision and hearing test. On one hand, I felt terrible for my dad. On the other hand, I appreciated that neither he nor I was not the appropriate judge of his driving ability or his safety and the safety of others, so long as he was behind the wheel.

    The National Institute on Aging, NIH, has several tips for helping people decide whether they should continue driving or rely on other forms of transportation.

  • What’s wrong with market innovations in health care?

    What’s wrong with market innovations in health care?

    Our government counts on market innovations in health care. It also allows companies to abandon these innovations as they please, with little concern for the harm it can cause Americans who depend on them. In an op-ed for Stat News, Claudia Jazwinska explains how the health care marketplace and our government can fail Americans who rely on health care innovations.

    Thousands of different implantable devices are in use around the globe, helping people. But, market pressures mean that these devices might not be reliable over the long-term. For example, hundreds of Americans rely on an implanted medical device in order to see. The Argus II is a retinal implant. But, its manufacturer, Second Sight, has stopped manufacturing it to avoid possible bankruptcy.

    When Second Sight discontinued the Argus II, people using it were left without vision and with an extremely expensive implant in their brain. They had no clue whether the device should be removed and, if so, who had the skills to remove it. They were left at serious risk because they had opted to use cutting edge technology, and the government did not step in to protect them.

    No one wants to inhibit meaningful innovation, which regulation can do. But, people who rely on medial innovations also need protections.

    The National Institutes of Health is continuing to support research from Second Sight even though it failed to continue the Argus II. The NIH is not supporting the patients who relied on its implantable device. It does not seem concerned about investing in companies that are not able to continue to service innovations that Americans rely upon them.

    Jazwinska asks why does our government allow companies to sell costly devices to Americans and then abandon them, especially when these devices are implanted into their bodies? At the very least, companies should be held accountable for doing so. Isn’t it negligence or malpractice to leave these people in the lurch?

    One solution would be to require these companies to make their proprietary devices open-source if they are discontinuing them. Other companies should be allowed to replicate them. Americans should not bear the burden of a company’s inability to continue a valuable technology.

  • Clinical trials need to include more older adults

    Clinical trials need to include more older adults

    Older adults have historically been excluded from clinical trials that test new drug treatments, even though older adults are most likely to need these treatments. Pratibha Gopalakrishna reports for StatNews that the problem continues. Even most reported Phase 3 COVID-19 clinical trials do not include older adults.

    Treatments should be developed with the needs of older Americans in mind, both in a pandemic and more broadly. Older adults have higher disease rates than younger people. The disproportionate number of deaths of older adults during this pandemic illustrates just how hard hit older adults can be from a transmissible disease.

    When older adults are not included in a clinical trial, it is much harder to know whether a drug will work for them, how safe the drug is, what the side effects might be, or how high a dosage they need. They might react very differently to a drug than a younger person.

    In January 2019, the National Institutes of Health released the Inclusion Across the Lifespan Policy. It requires that researchers include older people as well as younger people in their trials, if they are using NIH funding, unless there is a scientific or ethical reason not to. But, at least with cardiovascular trials that have taken place since this new policy, one in three trials still had age limits.

    In addition, some cardiovascular trials studied used exclusion criteria that were not age-specific. But, these criteria excluded people with pre-existing conditions, which includes most older adults. And, most studies were not looking to see whether a treatment benefited older adults.

    Perhaps, over time, the new NIH policy will bear fruit and do more to ensure new treatments are tested with older adults in mind. But, some experts say that a lot of the research is done on participants who are much younger on average than the age of people with serious diseases.

    Of course, in some cases, it may be perfectly appropriate to exclude older people from a trial because of risks of drug interactions, as well as compliance concerns, or inability to consent to the study. On top of these challenges to including older adults in clinical trials, there are challenges with identifying and recruiting older adult participants, along with transportation challenges.

  • What are probiotics and should you take them?

    What are probiotics and should you take them?

    These days, it seems that everyone is recommending particular diets to improve your health. And, lots of people, including Consumer Reports, are recommending probiotics, such as dark chocolate, greek yogurt, kimchi and sauerkraut.  What are probiotics and should you take them?

    According to the National Institutes of Health, probiotics are microorganisms similar to good bacteria in our guts. It warns that the U.S. Food and Drug Administration (FDA) has not approved any health claims about the benefits of probiotics.

    There is some evidence that probiotics can benefit people with diarrhea and irritable bowel syndrome. But, there is more research needed. Benefits have not been shown conclusively, and it’s not clear which, if any, probiotics are beneficial.

    The data suggest that side effects of consuming probiotic foods and drinks are few for people who are relatively healthy. But people who are critically ill with weak immune systems or post surgery could experience severe side effects, including infections.

    The NIH warns against taking probiotic dietary supplements, marketed like vitamins as capsules or tablets, without first talking to your doctor. They are not regulated by the FDA and it’s not always clear what ingredients they contain.

    [Editor’s note: New studies reported in StatNews continue to warn against taking probiotic supplements. They also suggest probiotics may not be good for your immune system. Findings from one small study show that people taking probiotic supplements who were also getting cancer immunotherapy treatment for melanomas were far less likely to respond to the treatment. Eating more fiber appeared to help people respond to immunotherapy treatment.]

  • UCLA helps Pharma keep drug costs high

    UCLA helps Pharma keep drug costs high

    On the morning of March 14, a first-year UCLA medical student named Kayla Gu approached the microphone at a meeting of her university’s Board of Regents. Speaking in a white coat with a stethoscope around her neck, she urged the university to drop a patent claim pending at India’s high court, which the David Geffen School of Medicine filed in order to block generic production of the prostate cancer drug enzalutamide, trade name Xtandi. Though developed at UCLA with tens of millions in funding from the National Institutes of Health and the U.S. Army, the drug giant Pfizer is making billions in profits by pricing a standard course of the drug at $130,000.

    “As medical students, we are proud to attend a public school with a social mission,” Gu told the regents, “[and] disheartened to see licensing decisions made here contribute to the rising cost of health care, and to keeping Xtandi out of the hands of poor people around the world.”

    That Pfizer would try to protect a profitable drug from generic competition is not surprising. It is, in fact, exactly the kind of corporate behavior we should expect in a system based on long-term monopoly patents. Gu’s question for the regents, one shared by the growing drug-access movement, is why a public university feels obliged to protect the industry’s criminal profit margins at the expense of many millions of human lives.

    “If Dreamworks made a film about the Xtandi case, the David Geffen School of Medicine would be the bad guy,” says Jamie Love, of Knowledge Ecology International, one of the groups at the forefront of the protest against UCLA’s patent claim. “The school’s decision to aggressively pursue patent protection in India for a pill that costs nearly 30 times per capita income for that country is an enormous disappointment.”

    The story of how UCLA became a Hollywood cancer villain is the story of a drug pipeline corroded and corrupted by monopoly patents, a corruption that reaches upstream to the NIH-funded labs where breakthrough research is conducted. The corruption of university labs is especially important, say reformers, because they represent an important vulnerability in a patent system. When new drugs are still being incubated in publically funded university labs, they can be pushed into open-access, royalty-free patent pools, and saved from the clutches of drug companies that will price them with Wall Street, not human or social needs, first in mind. This is how lifesaving HIV drugs became affordable in the late 1990s. A similar success occurred just last year, when Johns Hopkins granted the Medicines Patent Pool an exclusive royalty-free license to develop a promising tuberculosis drug.

    “If we can pressure universities from within to mandate access and affordability, it’s possible to build a new approach to drug development, one NIH-funded university lab at a time,” says Merith Basey, executive director of Universities Allied for Essential Medicines (UAEM).

    The UCLA case illustrates the challenge of making open-access agreements the new norm. On paper, the University of California professes to share the values and goals of drug-access groups like Basey’s and the Union of Affordable Cancer Treatment. In 2009, the UC system pledged to practice “humanitarian patenting and licensing strategies” that would reflect a “public benefit mission” and “promote access to new drugs, especially in the developing world.”

    But the school’s legal efforts in New Delhi make a mockery of this pledge. Very few prostate cancer patients in India, or in any other country, can afford Xtandi sticker prices ranging from $30,000 (Canada) to more than $130,000 (the U.S.). If UCLA was committed to “humanitarian licensing practices,” it would get out of the way of the Indian companies that stand ready and able to start producing generic versions of Xtandi for as little as $200 per course.

    UCLA is defending its position by pointing to the contractual language of its industry partnerships. In September 2017, UCLA’s Vice Chancellor of Health Sciences, John Mazziotta, wrote a letter to the Union of Affordable Cancer Treatment saying the school had to do Pfizer’s bidding because of “the terms of [a] licensing agreement [that gives] the licensee substantial input and control on [the patent’s] prosecution and maintenance.”

    If UCLA wants to choose Pfizer’s side in the Xtandi fight, it can do that. But everyone should understand it is a choice. The school could as easily point to its “humanitarian” obligations as written in its institutional licensing guidelines, which can be read as contractual obligations to California, the U.S. and the human race. Instead, it has chosen to reinforce a corporate royalty and patent model. In the case of Xtandi, this model has rewarded the school’s coffers with roughly $500 million in royalties.

    “Apparently, UCLA wants to preserve its relationships with companies for the next big blockbuster developed on campus,” says Reshma Ramachandran, a resident doctor at Kaiser Permanente Los Angeles Medical Center and a UAEM board member.

    “This product was developed at a public institution with taxpayer dollars, and then licensed to companies without guarantees for affordability. It’s alarming to see UCLA going even further to prevent generic competition here in the U.S. and in developing countries.”

    Xtandi’s journey from a public lab to a patent fight followed a well-worn path. In 2005, after hatching the breakthrough drug, UCLA licensed it to a biotech firm, Medivation, that partnered with a larger company, Astellas Pharma, to bring it to market. When the FDA approved Xtandi for sale in 2012, the companies quickly racked up $2 billion by selling eight- to 12-month courses of the drug for six figures.

    The drug’s early profits—combined with the growth of prostate cancer worldwide—drew the interest of bigger players and Wall Street. But before a major drug company spent billions on Medivation and the Xtandi license, they waited for the U.S. government to quash attempts by Democratic lawmakers and drug-access groups to license a generic version. This outcome was never in doubt, and in June 2016, NIH officially rejected an offer by Biolyse Pharmaceuticals to produce and sell generic versions of enzalutamide for five percent of the monopoly patent price. Shortly after the decision, Pfizer won a bidding war for Medivation, acquiring the company for $14 billion.

    Other countries, however, remained a “threat” to global Xtandi profits. The biggest of these threats was the world’s generics superpower, that “pharmacy of the poor,” India. In 2016, the India Patent Office rejected UCLA/Pfizer’s first attempt to block generic competition, citing “obviousness and lack of patentable invention.” This set the stage for UCLA’s current appeal before India’s high court, in which Pfizer lawyers have power of attorney. Although UCLA makes no mention of its commercial partner in the filing, the school has admitted that it is essentially waging a proxy battle on behalf of Pfizer.

    UCLA has responded to growing calls to withdraw its case with that squishiest of things: the announcement of a working group to study the problem. This working group, says the administration, will “evaluate our approach to technology licensing in ways that benefit California, the nation and the developing world.”

    As it conducts this evaluation, millions of men with late-stage prostate cancer will die earlier than they have to. The majority of these people live in developing countries that depend on India for affordable generics. Though multiple Indian companies could begin producing the drug immediately, they are hand-tied until the resolution of UCLA’s claim. Last summer, a leading patient-activist in Chile, Pino Cataldo, died from prostate cancer before he could get the drug.

    “The David Geffen School of Medicine and the Regents of the University of California know the consequences of what they are doing, because they have been told several times,” says Jamie Love. “They just don’t care.”

  • Drug companies must now disclose most clinical trial results

    Drug companies must now disclose most clinical trial results

    For years, drug and medical device companies have been able to conduct clinical trials and then, depending upon results, determine which ones to make public. They were not required to let the public know about poor outcomes of clinical trials, even for a drug receiving FDA approval based on a different clinical trial with a beneficial outcome. Now, these companies must disclose most clinical trial resultseven if they show a drug or device may not be safe or effective.

    The U.S. Department of Health and Human Services has issued a final rule expanding the conditions under which pharmaceutical companies, medical device companies and manufacturers of biologics must register clinical trials and disclose summary results information on ClinicalTrials.gov, including information about harmful side effects.  The National Institutes of Health has issued a policy that complements the HHS policy for registering and disclosing summary results information on ClinicalTrials.gov for all NIH-funded trials, including trials that are not subject to the HHS final rule.

    NIH Director Francis S. Collins, M.D. said that he wanted to make sure the public got maximum value from clinical trials, whether funded with government money or private money. “Access to more information about clinical trials is good for patients, the public and science.”

    The goal of clinical trials is to ensure that health care drugs and devices are safe and effective. They sometimes also indicate when one medical treatment is better for a specific condition or particular subpopulation (e.g., children, older adults) than another.

    These new requirements should make it easier for people to learn about clinical trials in which they might be interested in participating as well as new possible treatments for their conditions. And, more information about clinical results will enable patients and doctors to make more informed decisions about appropriate treatments. It will also help researchers design studies based on more information about clinical trial results.

    The HHS final rule requires companies to register and disclose summary results for trials of most products that the FDA regulates. However, phase 1 drug and biological products and small studies to determine the feasibility of device products are excluded from the requirement. The NIH policy extends to all NIH-funded trials, including phase 1 clinical trials of FDA-regulated products and small studies to determine the feasibility of products; it also applies to products that the FDA does not regulate, including behavioral interventions.
