In the pandemic, we need to rediscover patience and grasp our responsibility


In this time of pandemic, the virtue of patience is paramount. So is the need to grasp our impact on the history of the planet and its effect on our lives. We who are afflicted with rare diseases have already had to learn many hard life lessons, which apply to the vital efforts to confront the coronavirus. 

As we mark Huntington’s Disease Awareness Month, we recall how many in the HD and other neurological and rare disease communities have demonstrated great fortitude and also patience as we await effective treatments. Since learning of my mother’s diagnosis with HD in 1995 and my positive test for the mutation in 1999, I have worried about the inevitable onset of symptoms and yearned for a successful clinical trial to produce a drug to stave off the disease or ameliorate it.

“HD warriors” like my mother and caregiver father (both deceased) have had to confront the disease on a daily basis for a decade or longer. 

Drugs like tominersen, the gene-silencing compound now in a historical Phase 3 clinical trial run by Roche, require painstaking development and often well over a decade to reach the market.

The tominersen project began in 2007, and Roche expects to analyze Phase 3 data in 2022. (Tominersen was previously known as RG6042 and, before that, as IONIS-HTTRx.)

The best-case scenarios for an effective and safe COVID-19 vaccine for the general public point to some time in 2021. 

“What people don’t realize is that normally vaccine development takes many years, sometimes decades,” Dan Barouch, M.D., a virologist at Beth Israel Deaconess Medical Center in Boston, stated in a news report. “And so trying to compress the whole vaccine process into 12 to 18 months is really unheard-of.”

A vaccine might never be found; after decades of intense research, science still has not developed one for AIDS.

Drug development requires precision and patience.

Possible hope from new drug development approaches

That said, by dint of biomedical progress (but lacking overall preparedness for a pandemic), the current worldwide effort could take place more rapidly than previous drug-development work.

With positive results in the very early stage of its vaccine program, drug maker Moderna, Inc., is using an RNA-based approach to attempt to block the actions of the coronavirus.

Ionis Pharmaceuticals, Inc., the developer of tominersen, is also looking into ways its drug technology “could benefit COVID-19 patients, first by looking at our existing pipeline to see if any clinical or preclinical drugs would have a use in treatment in either the disease, or more likely the complications of the disease arising from the acute respiratory syndrome,” Eric Swayze, Ph.D., the firm’s senior vice president of research, wrote in an e-mail to me on May 8. Ionis designs drugs using antisense oligonucleotides (artificial strands of DNA), a form of gene silencing technology.

“In the 2002/2003 SARS epidemic we did done some work with ASOs targeting both the coronavirus itself as well as host factors, and had preliminary hints of activity [effect],” Swayze added. “Because of this, we are making newer generation ASOs targeted to the SARS-CoV-2 [COVID-19] virus as well as host factors that contribute to the infection and disease. 

“We plan to work with collaborators who have the capability to test our lead ASOs in virus cultures. We believe that our recent pulmonary program advances position us to quickly move forward, provided that our drugs look promising. However, we feel this remains a high-risk discovery project, with many challenges ahead.”

Behind the reaction against lockdowns

However, despite the need for a long-term fight against COVID-19, only a few weeks after lockdowns began, tiny groups of purported “protestors” appeared demanding to “open up” states. They were egged on by President Donald Trump, who has declined to marshal national resources against the virus, and organized by conservative groups.

I have wondered: What if Americans had wanted to give up only three weeks after the 1941 attack on Pearl Harbor?

The initial impatience about COVID-19 was clearly politically motivated. Since then, some criticism of lockdowns results from growing economic hardship: with a 14.7 percent unemployment rate, the U.S. has lost the greatest number of jobs since the Great Depression of the 1930s. In addition, many small business owners have had to curtail their work or even shut down completely.

The pain hits professors and students

The economic pain has hit American universities such as my employer, the University of San Diego (USD), which switched to remote, online instruction in mid-March. Confronting an unexpected deficit, the president has announced a 50 percent cut in retirement benefits and a salary and hiring freeze.

There is no consensus nationally on how to resume classes in the fall, with leaders of different campuses struggling with uncertainty. The nation’s largest public university, California State University, for example, has announced, that its campuses will move nearly all instruction online.

With USD’s dependence on tuition for institutional survival and its reputation for high-quality instruction in relatively small classes in small classrooms, the administration has launched a still inchoate plan to reopen for the fall semester early, in mid-August. According to administrators, because of the loss in student fees, going remote again would extend losses by tens of millions of dollars, forcing possible layoffs and furloughs of some instructors and employees, an increased teaching load for the main faculty, and other types of cutbacks.

Many professors, including myself, fear returning to campus so soon; in normal times, packed dorms, classrooms, and other facilities (and student parties administrators can’t control) provide ideal conditions for a virus to spread. Though young people are less likely to suffer from coronavirus symptoms, some do get serious cases, and asymptomatic people can of course spread the virus to others more vulnerable.

Universities and their employees will seek to implement social distancing, testing for COVID-19, and other measures. Ultimately, depending on the course of the pandemic, many might have to resort again to remote learning.

We cannot return to ‘normal’

In fact, three in four Americans have supported social distancing and wearing masks.

Without good health, we are restricted economically, as the HD community knows so well.

I believe that the impatience comes in part from our culture of instant gratification, epitomized by online shopping and overnight delivery. Another part relates to political orientation, with Republicans favoring a more rapid opening than Democrats (for one analysis, click here).

I think many people – myself included – wrongly thought that, after a month or two of lockdown, we would return to “normal.”

However, as New York Governor  Andrew Cuomo put it on April 1, “I don’t think we get back to normal. We get to a new normal.” As a result of the crisis, society will undergo a “transformation,” and we must assure that it be “positive and not negative,” Cuomo urged.

“I fear that the resumption of normality would signal a failure to learn,” commented Pulitzer-Prize-winning medical writer Siddhartha Mukherjee, M.D. “We need to think not about resumption but about revision.”

He added, with reference to how the drive for instant success has exacerbated the pain of the pandemic: “To what extent did the market-driven, efficiency-obsessed culture of hospital administration contribute to the crisis?”

The perspective of Big History

Cuomo echoed the point that professional historians like me make to students and readers of our books: history is ever-changing, often with great progress, but also devastating setbacks, including world wars, plagues, and inhumane practices like slavery.

I teach a course called “Big History: From Cosmos to Cannibals,” which begins with the start of the universe and ends with the dawn of the modern era: Europeans' conquest of the Americas, beginning in the late 1400s and quickly causing epidemics of Old World diseases in which tens of millions of native Americans died in the hemisphere – a very poignant point of comparison with the pandemic this past semester. A field that has emerged recently, Big History embraces the idea that human development must be understood in the context of physics, biology, evolution, and the transition from small bands of hunter-gatherers to cities with millions of people.

Over the past several years, my classes have focused on how we now live in the Anthropocene, an era in which humans have taken control of the earth’s systems (atmosphere, oceans, land, life, and others).

Human agency has led to global warming, probably a more daunting challenge to humankind than coronaviruses, and many other threatening phenomena.

Human control has contributed to the crisis

In fact, some commentators have asserted that the pandemic has resulted from the humans’ super-control of the earth and our encroachment on the last vestiges of nature in areas such as the Amazon rainforest (for some examples, click here, here, and here).

Deforestation (for cash crops and cattle), mining, a growing population, and the expansion of urban areas have put the environment and the species therein under greater stress, making them more susceptible to viruses and zoonosis (jumping of a virus from one species to another, including humans).

Human domination of the planet has intensified over the past several decades. I witnessed the devastation firsthand of the Amazon in 1988 and 1990, during my time in Brazil as a graduate student. I saw gold prospectors who penetrated the deepest recesses of the forest, using clandestine airstrips. I also viewed up close how many square miles of trees had been cut down.

Reconnecting with ourselves, and the planet

In my Big History course just concluded this semester, we were all deeply saddened by the onset of the pandemic. However, in the context of history, a devastating viral outbreak was highly likely. Leading scientists have also warned the world for decades.

The pandemic serves as a global alarm. The Earth is a system, and it is crying out against our dangerous intrusions into rainforests and other attacks on the environment. Ironically, with the decrease in vehicle traffic, the vast reduction in pollution gives us a glimpse of the air quality we once had and must achieve again to stem the tide.

A key lesson of my Big History course is that the modern world led humans to think they were separate from nature, but, in reality, we are ever more interconnected. The pandemic will perhaps force humanity to rediscover our identity (for some, a spirituality) of being one with nature. We are part of the Earth, not over and above it.

As Dr. Mukherjee pointed out, the virus has laid bare many things, such as the inequality of our health system. It has also laid bare our impatience. To overcome the virus, we need to regain patience and, along with it, humility and respect for the planet.

As Dr. Mukherjee and others have urged, we also need to learn from this crisis and make better policy choices for future threats of all types.

Hacking humans, upgrading Homo sapiens: the role of the Huntington’s disease community and the consequences for life


An influential book by best-selling historian Yuval Noah Harari, Homo Deus: A Brief History of Tomorrow, looks broadly at potential medical advances, thus providing hope for the Huntington’s disease community’s quest for a cure, but it also warns of the vast consequences for human life caused by the advance of biotechnology and the accumulation and control of data.

A professor in the History Department at the Hebrew University of Jerusalem and holder of a Ph.D. from the University of Oxford, England, Dr. Harari published the international blockbuster Sapiens: A Brief History of HumankindSapiens was first published in Hebrew in 2011 and was translated into nearly 50 languages, selling over 10 million copies by 2018.

In Sapiens, Dr. Harari uses macro-history (also known as “big history”) and biological evolution to explain the development of human society over the past several hundred thousand years. He focuses in particular on the “cognitive revolution” that began 70,000 years ago. During this period, the modern human species, Homo sapiens, came to dominate Earth.

“Homo sapiens” is Latin for “wise man.” “Deus” means “god.” In Homo Deus, first published in English in 2016, Dr. Harari projects current trends deep into the 21st century and speculates that humanity could double average life expectancy to 150 years. He also considers the profound changes longer lives would bring such as people in positions of authority stretching out their careers and thus cutting off opportunities for younger individuals.

Ultimately, in this century humanity may seek immortality by developing new biomedical tools and implants, fusing our bodies with high-tech machines, and perhaps also creating non-organic beings.

“You may debate whether it is good or bad,” Dr. Harari writes, “but it seems that […] the twenty-first century will […] involve re-engineering Homo sapiens so that it can enjoy everlasting pleasure. In seeking bliss and immortality humans are in fact trying to upgrade themselves into gods. Not because these are divine qualities, but because in order to overcome old age and misery humans will first have to acquire godlike control of their own biological substratum [bedrock].”



A new scientific dogma: we are algorithms

The idea of ending disease and extending life, even if by only a few years, stirred the depths of my being. The fear of death propels our psyches and civilization. In the Huntington’s community, where the disease’s devastating and fatal symptoms cut off down lives early, the fear of death is ever-present and more acute. I recalled my mother’s death from HD in 2006 at 68 and my condition as an HD gene carrier. At 59, each day without symptoms is a blessing.

Homo Deus also reminded me of my 2010 article “God, Huntington’s disease and the meaning of life,” in which I examined the Catholic Church’s little-known and little-understand acceptance of evolutionary theory and the notion that the Resurrection of Christ could be seen as a genetic mutation.

However, in Homo Deus Dr. Harari also warns that current trends in biotechnology and the gathering and control of data could also lead to the creation of a super-human elite taking control of the rest of humanity, threatening privacy, democracy, and human and civil rights.

“If indeed we succeed in hacking and engineering life, this will be not just the greatest revolution in the history of humanity,” Dr. Harari told the audience at the 2018 World Economic Forum Annual Meeting in Davos, Switzerland. “This will be the greatest revolution in biology since the very beginning of life 4 billion years ago.[…]

“Science is replacing evolution by natural selection with evolution by intelligent design. Not the intelligent design of some god above the clouds, but our intelligent design, and the intelligent design of our clouds, the IBM cloud, the Microsoft cloud. These are the new driving forces of evolution.”

In Homo Deus, Dr. Harari explains that “science is converging on an all-encompassing dogma, which says that organisms are algorithms” – a method or list of instructions for making calculations – “and life is data processing.”

“Humans are algorithms that produce […] copies of themselves,” he adds. The influence of computer algorithms designed by organizations such as Google has grown vastly, taking in fantastic sums of personal data for users of the Internet and personal devices. “Non-conscious but highly intelligent algorithms may soon know us better than we know ourselves.”

In their digital lives, over 2 billion Facebook members have encountered that organization’s problematic algorithm, which a company study found to be a better reader of people’s personalities than even their friends, parents, and spouses, Dr. Harari points out.

Crucial data from HD families

Homo Deus doesn’t mention HD. However, it recognizes the importance of Alzheimer’s disease and the need to prevent it and disease in general. Dr. Harari explains that upgrading humanity would include attempts to expand the abilities of the brain – which, of course, is an organ severely debilitated by HD.

The history of the search for HD treatments is key to the biotechnological revolution. HD-affected individuals and their families have both witnessed and participated in that revolution, starting with the hunt for the huntingtin gene in the 1970s, 1980s, and 1990s, and since then with a growing number of research studies and clinical trials involving thousands of individuals.

At the start of this decade, CHDI Foundation, Inc., the nonprofit virtual biotech focused on defeating HD, pioneered the use of systems biology, which includes the deciphering of vast amounts of biological data, in disease treatment (click here to read more).

CHDI has also collaborated with IBM to seek deeper understanding of the huntingtin protein’s role in the disease. In this effort, IBM has provided its immense computational power and the tools of big data analytics.

Enroll-HD, the CHDI-sponsored worldwide database of HD-affected individuals and family members, has more than 17,000 participants. Thousands of HD-affected individuals and gene carriers have also participated in the research involving the search for so-called modifier genes that affect the age of onset. The scientists have analyzed millions of small variations in these people’s genes.

Digital monitoring and algorithms

An increasing number of researchers and companies are in effect trying to hack HD’s genetic causes. The most prominent is the gene-silencing drug developed by Ionis Pharmaceuticals, Inc., in collaboration with CHDI and other researchers. On December 19, pharma giant Roche, now the drug’s license-holder, announced the first 26 planned sites for the crucial global Phase 3 trial to test the drug’s efficacy.

In that trial, participants will receive the drug via lumbar puncture (spinal tap), the first time this delivery method is being used extensively in an attempt to treat a neurological disorder.

For the study, Roche has designed an HD Digital Monitoring Platform, which will continually measure participants’ biometric data using smartphones and watches.

“The software is what’s special, and the analytics engine behind it,” Erik Lundgren, the Roche lifecycle leader of the HD team, said in an interview last March. “A tremendous amount of data comes in. The algorithms and how you make sense of that is what our team has been working hard on developing.”

Privacy versus healthcare systems

As Dr. Harari warns, the purpose and uses of technologies and information-gathering techniques originally developed for something positive such as curing a disease could result in unintended, perhaps negative, consequences.

Companies such as Google “want to go much deeper than wearables,” he explains.

“If we give Google and its competitors free access to our biometric devices, to our DNA scans and to our medical records, we will get an all-knowing medical health service that will not only fight epidemics, but will also shield us from cancer, heart attacks and Alzheimer’s,” he writes.

However, he observes, “imagine a system that, in the words of the famous Police song, watches every breath you take, every more you make and every bond you break; a system that monitors your bank account and your heartbeat, your sugar levels and your sexual escapades. It will definitely know you much better than you know yourself.”

Google and these other algorithm-based systems could make decisions for us, from selecting which movie to watch to choosing a spouse to settling on a candidate in the voting booth.

In a world in where the stress on data takes on a religious fervor, the demand for the free and massive flow of information could trump freedom of expression and, by extension, people’s right to control their own information, Dr. Harari asserts. He cites pressure from “Dataist missionaries” for free access to all information, including copyrighted materials.

The danger is that “we will just have to give up the idea that humans are individuals, and that each human has a free will determining what’s good, what’s beautiful and what is the meaning of life.” 

“The big battle over what we today call ‘privacy’ will be between privacy and health,” Dr. Harari asserted at the World Economic Forum. “Do you give access to what is happening inside your body and brain in exchange for far better health care? And my guess is that health will win, hands down.[…] Maybe in many places [people] won’t have a choice. They won’t get insurance if they are unwilling to give access to what is happening inside their body.”

What kind of world are we creating?

Because of the many critical issues it touches on regarding humanity’s future, Homo Deus is a must-read book.

For the HD community, it provides valuable context for the difficult medical, social, and ethical challenges involved in the disease and the quest for treatments.

As many in science strive, in Dr. Harari’s words, to “defeat death and grant humans eternal youth,” the complexities of HD and the close collaboration between HD scientists and families may serve as a reminder that the biotechnological and medical sectors should consult disease communities and the rest of society.

Yes, despite having back problems, to avoid HD onset I would take a drug via recurring spinal taps. I would also wear a data monitor, as do people with type 1 diabetes, for example.  

However, I’m also concerned about the dystopian scenarios outlined by Dr. Harari for this century.

What kind of world are we creating for our children and grandchildren?
