Ten years out of the terrible and lonely Huntington’s disease closet, as new research and investments offer hope for treatments

 

Ten years ago this month, I exited the “terrible and lonely Huntington’s disease closet” by publishing an essay on my plight and advocacy as an HD gene carrier in The Chronicle of Higher Education.

 

Fortunately, asymptomatic as I near 63, I continue to teach, research the history of the HD cause, and enjoy family milestones such as my gene-negative daughter Bianca’s graduation from college and my wife Regina’s and my 30th anniversary celebration – events that I feared HD would prevent me from appreciating.

 

As we approach Thanksgiving, my favorite holiday, I feel a profound gratitude to my family, friends, and colleagues at work and in the HD cause.

 

So I want to reflect on my journey since exiting the closet. I also want to report on new paths of research that could offer hope for what we in the HD community (and beyond) desperately await: effective therapies (treatments).

 

Becoming a more effective – and convincing – advocate

 

I started this blog in January 2005 under the pseudonym Gene Veritas. Having told my family’s story using my real name (Kenneth P. Serbin) in a widely read publication has enabled me to become a more effective – and convincing – advocate. I could now speak with full transparency about HD, provide an example for others still hiding in the closet, and build new partners in the fight to raise awareness and funds.

 

Before exiting the closet, I was sheepish about fundraising and other aspects of my advocacy, restricting my efforts to relatives and close friends who knew about my family’s struggles. After my exit, I became more self-assured.

 

In 2013, the Serbin Family Team in the annual Hope Walk of the Huntington’s Disease Society of America (HDSA) became the top fundraiser nationwide, taking in more than $16,000 in donations from dozens of generous supporters.

 

Collaborating with work colleagues

 

I most feared the consequences of revealing my story at my workplace, the University of San Diego (USD), because of concerns about discrimination. I knew HD gene carriers had been fired by their employers. My USD colleagues were shocked by my revelation.

 

However, those colleagues ultimately showed great solidarity. By advocating about HD at work, I attracted new allies, boosted awareness, and served as a bridge to resources for those facing HD (click here to read more).

 

My advocacy reached a milestone in May 2017, when I traveled with my family to Rome to help represent the U.S. HD community at HDdennomore: Pope Francis’ Special Audience with the Huntington’s Disease Community in Solidarity with South America. My trip was sponsored by several USD units, including the Frances G. Harpst Center for Catholic Thought and Culture, directed by Jeffrey Burns, Ph.D. Later that year, the center hosted a talk by me exploring the social, scientific, and religious meaning of this extraordinary the papal event.

 

Francis became the first world leader to recognize HD, declaring that it should be “hidden no more.”

In early 2020, before the coronavirus pandemic exploded in the U.S., Dr. Burns and I collaborated in a screening at USD of the short documentary Dancing at the Vatican, which features HDdennomore. In late 2020 I helped promote the launch of the film online.

 

This year, I fulfilled one of the long-term goals outlined in my 2012 coming-out essay: shifting my academic focus from my beloved Brazil to the history of the quest for HD therapies.

 

With support from USD and The Griffin Foundation, I submitted the project for funding to the National Science Foundation. Although I was not granted funding initially, the foundation’s program officers encouraged me to reapply.

 

PTC’s helpful infusion of new capital

 

We all anxiously await effective therapies. Over the past ten years, I have increased my attention to the intensification of the efforts by labs and biopharma companies to achieve success.

 

The last several years of such efforts have felt like an emotional roller coaster for the HD community, though that’s not unusual for a difficult endeavor like drug development, which involves both positive and negative clinical trial results and cumulative learning.

 

Last month, I reported on the abrupt shutdown of the firm Triplet Therapeutics, Inc., which had explored a much-awaited proposed therapy. I also noted that the U.S. Food and Drug Administration (FDA) had requested that PTC Therapeutics, Inc., provide further information before allowing a clinical trial of its HD drug, PTC518.

 

But there was also potential good news.

 

Despite the FDA-imposed delay in a U.S. trial, PTC has reached a financing deal with the investment firm Blackstone, based on PTC’s plans to expand its drug pipelines to other diseases. The deal, which in the best-case scenario could infuse $1 billion of investment, puts “PTC in a strong position to continue to execute our mission,” Emily Hill, PTC’s chief financial officer, stated in an October 27 press release.

 

PTC518, a so-called splicing molecule, is also classified as a small molecule drug. It is thus taken as a pill – in contrast with riskier, less convenient delivery methods used by other HD programs, which include brain surgery and spinal injections. Early next year, PTC will furnish an update on the PTC518 trial. The trial continues in several European countries and Australia.

 

Roche diversifies its approach

 

In March 2021, Roche reported disappointing news: its gene silencing drug tominersen (an antisense oligonucleotide, or ASO) failed to improve symptoms in volunteers in the firm’s GENERATION HD1 Phase 3 (large-scale testing of effectiveness and safety) trial. This September, Roche announced GENERATION HD2, a less ambitious, Phase 2 (effectiveness, dosage, and safety) retesting of tominersen to start in early 2023.

 

In its presentation of GENERATION HD2 at the annual Huntington Study Group annual meeting in Tampa, FL, on November 3, Roche revealed that it has expanded its pursuit of HD therapies by embarking on two preclinical (nonhuman) projects.

 

Whereas tominersen targeted both the normal and abnormal (expanded) huntingtin gene, Roche will now seek to develop a drug that aims at just the abnormal gene. (Wave Life Sciences already reported in September that it had successfully targeted the abnormal gene in an early stage clinical trial, although yet without evidence of impacting symptoms.)

 

Like PTC’s program, Roche’s second preclinical program will aim at developing a splice modifier that would be taken orally.

 

“The medical need in the HD community is clear and we recognize that a range of different therapeutic approaches are likely to be required,” Mai-Lise Nguyen, of Roche’s Global Patient Partnership, Rare Diseases, wrote me in a November 3 e-mail.

Another ten years?

 

After the major disappointment in the shutdown of Triplet, I was heartened to learn of Blackstone’s massive investment in PTC, which indicates that both firms see PTC’s potential treatments as viable and profitable.

 

I was also encouraged to see how Roche, in the words of its Huntington Study Group presentation (see photo below), has augmented its HD research portfolio, reflecting a “commitment to advance scientific understanding and drug development in HD through continued collaborations” with HD organizations.

 

With the ingenuity of HD scientists and the dedication of HD family members to participation in research, the march towards potential therapies continues. I hope to chronicle continuing progress over the coming years not only free of the “HD closet,” but, thanks to new therapies, free of significant HD impacts, as well.

Happy Thanksgiving! And hail to the pharmaceutical and biotech industries – and the scientists!

Thanksgiving this year is going to be radically different for many Americans, including my family.

 

I will celebrate my favorite holiday just with my wife Regina, home in San Diego.

 

As it has for many Americans, the COVID-19 pandemic has prevented us from hosting our usual small group of friends.

 

After eating a healthy brunch, we plan to have a Zoom call with our HD-free “miracle” daughter Bianca, a junior history major at the University of Pennsylvania. We are ever thankful that Bianca did not have to face the devastating possibility of juvenile HD. We will miss her, but are reassured knowing that she will spend the day with her boyfriend and his immediate family in the East.

 

We also hope to Zoom with some of our local friends. 

 

However, despite the terrible pall cast by the pandemic over the 2020 holiday season, I feel extremely optimistic that researchers will find a highly effective vaccine for the coronavirus.

 

The announcements of preliminary data by Moderna and the team of Pfizer and BioNTech revealed that their vaccine candidates reduced COVID-19 infections by 95 percent in clinical trials.

 

Dr. Anthony Fauci, the director of the National Institutes of Allergies and Infectious Diseases (NIAID), described the Moderna data as “stunningly impressive,” noting that he would have settled for 70-75 percent efficacy in a vaccine.

 

“It is really a spectacular result that I don’t think anybody had anticipated would be this good,” Dr. Fauci said. He had similar praise for the Pfizer/BioNTech data.

 

Both of these trials use genetic approaches: they introduce the virus’s own genes into cells to provoke an immune response.

 

According to the New York Times’ Coronavirus Vaccine Tracker, several dozen other companies have embarked on clinical trial programs using some form of approach based on genetics or other cutting-edge strategies. Only ten projects are making vaccines using the traditional approach of injecting weakened or dead coronaviruses.

 

In all, scientists are testing 54 vaccines in clinical trials, and at least 87 more are under investigation in animals.

 

Genetics-based approaches are familiar to the HD community, where researchers have investigated the potential of gene silencing drugs for more than a decade. Researchers in the lead program, Roche’s historic GENERATION HD1 Phase 3 clinical trial, hope to analyze data in 2022. 

 

When I heard of the initial reports of Moderna’s genetics-based approach, I felt deeply confident that humanity would ultimately defeat the coronavirus. 

 

The potentially record speed in getting a vaccine to the world is testimony to the ingenuity, dedication, and focus of the biotech and pharmaceutical industries, which I have observed with deep interest in my nearly quarter century as an HD advocate and student of the science – and as a writer summarizing the science in simple terms.

 

In October, posting on Facebook an article on the bold Triplet Therapeutics clinical trial program – yet another genetics-based effort – I wrote the following: “Hail to the many imaginative and hard-working companies in America’s pharmaceutical industry!”

 

I also salute the scientists involved, and the many pharmaceutical and biotech firms of other nations engaged in the fight against COVID-19 and HD.

 

Also, we must not forget the millions of doctors, nurses, and other healthcare workers and first responders who have heroically attempted to hold the line against COVID-19, thus giving the researchers the time necessary to develop the vaccines.

 

Thanksgiving is our quintessential American holiday. This year, with the pandemic, it takes on a global significance. Across all cultures and nations, the virus has led us to realize once again our common humanity – and the collective efforts needed to safeguard life for all.

An ‘electric,’ inspiring Thanksgiving for the Huntington’s disease community

Thanksgiving is my favorite holiday. I’ve reflected on it many times in this blog. For me, rather than the commercialism and stress associated with the holidays, it’s truly a day of relaxation, the warmth of friends and family, and gratitude.

This year, the Huntington’s disease community has bountiful reasons for thanks. Several clinical trials to test what might become the first effective treatments are in progress, and the community has demonstrated spirited participation.

The historic Roche gene-silencing program successfully started its crucial third and final phase, GENERATION HD1, earlier this year. The program includes an open-label extension of all 46 participants in the first phase, completed in December 2017, all of them receiving the drug RG6042 via a monthly injection into the cerebrospinal fluid (CSF).

“Two years ago, we showed for the first time – about 25 years after the discovery of the gene –the ability to lower CSF levels of mutant huntingtin [protein] in patients with HD, which was a very exciting first-in-human accomplishment, and that was really the springboard that allowed us to proceed to our global development program,” Scott Schobel, M.D., M.S., Roche’s associate group medical director and clinical science leader for RG6042, reported at the 26th annual Huntington Study Group (HSG) meeting on November 8. “So these heroic 46 volunteers were the foundation of that.”

GENERATION HD1 is “recruiting incredibly well,” Dr. Schobel said. “It’s been absolutely electric.” Total worldwide enrollment in GENERATION HD1 and related studies has surpassed 800. “It’s been a huge response from the community,” he added.

Several other programs provided updates at the HSG meeting.

Although much work remains to develop effective therapies, HD families and their supporters can feel proud for helping further the progress achieved in 2019.

Priscilla’s inspiring fight and peaceful paintings

An HD-stricken woman I know from Brazil, Priscilla Ferraz Fontes Santos, embodies the life-force of the HD cause. I saw Priscilla in 2013 at the sixth World Congress on Huntington’s Disease in Rio de Janeiro, and got to know her at #HDdennomore, Pope Francis’ special audience with the HD community in Rome in 2017.

Brazilians don’t celebrate Thanksgiving, but Priscilla’s words, paintings, and photos help us feel the peace and hope of our quintessentially American holiday.

Priscilla was stricken with juvenile HD as a teenager. She had played soccer, pursued acting, and completed her journalism degree, but the disease prevented her from finishing a second degree in tourism.

Many juvenile patients do not live past 30. Priscilla is 36. She takes no drugs to control her involuntary movements and other symptoms but instead relies on alternative and spiritual approaches, including yoga. However, she also follows HD clinical trials and hopes for a cure.

Starting November 22 and ending December 10, Priscilla and her art teacher are staging an exhibit of Priscilla’s paintings in Serra Grande, a town in the state of Bahia. They have called it “Colored Atmosphere.”

“The past two and a half years, I have been taking painting and art classes, and I have discovered for myself the pleasure and well-being that painting brings,” Priscilla wrote in an introduction to the exhibit. “As I await the cure, I have gained the courage to overcome many difficulties and meet challenges with the ever-present support of my family, friends, and health professionals who care for me.”

Priscilla ended with this wish: “I hope that you enjoy my paintings and that they awaken in you all of the strength, beauty, and joy with which I painted them.” (I translated the text from the original Portuguese.)

Priscilla is an “inspiration of strength and positive thinking” for all of us, Priscilla’s mother Lígia wrote in a message in Brazilian WhatsApp group dedicated to the HD cause.

Symptom-free, but awaiting treatments

As always, I am profoundly grateful for not having yet developed any of the inevitable classic symptoms of HD, which struck my mother in her late 40s and ended her life at 68.

I turn 60 next month – an age at which my mother had full-blown HD and could no longer care for herself.

Last week, I presented my new book on Brazilian history to an audience at the University of San Diego. I had never imagined I would still be able to write at age 60.

Even more importantly, I’m able to continue supporting and loving my wife Regina and daughter Bianca. A sophomore at the University of Pennsylvania and HD-free, Bianca will spend Thanksgiving with friends in Connecticut. However, in a few weeks she will be home for winter break.

I am crossing my fingers that GENERATION HD1 and other trials can produce an effective treatment – and that I can hold on long enough to benefit and share more precious time with my family.

This Thanksgiving, appreciating stable health and new plans for Huntington’s disease advocacy

This Thanksgiving, I am especially grateful for good health – and all that it enables me to enjoy.

At my annual neurology checkup on October 31, the doctor told me that I remain asymptomatic for Huntington’s disease. My more extensive annual Enroll-HD examination earlier in the year also showed no symptoms. 

I tested positive for the HD gene in 1999. Next month, I turn 59. At that age, my mother had already been diagnosed and was rapidly losing the ability to walk, talk, and care for herself. She died in 2006 at the age of 68 after a long struggle.

I never imagined that at this point I could still pursue my passion for writing, teach at the university, and support my family.

As I frequently tell students, colleagues, and my family, “health is first.” Without it, achieving goals and handling responsibilities can become very difficult, if not impossible.

Studying the history of the HD cause

I am putting the final touches on a book in my field of Brazilian history, scheduled to be published next June, From Revolution to Power in Brazil: How Radical Leftists Embraced Capitalism and Struggled with Power. I began the research more than two decades ago, not long after learning of my mother’s HD diagnosis. Seeing the project come to fruition is thrilling and profoundly fulfilling.

With the Brazil project complete, I will carry out my long-gestating plan to shift my main scholarly focus to the history of science, technology, and medicine. Last month I proposed a new, multi-year research project, titled “Racing Against the Genetic Clock: A Social, Scientific, and Personal History of the Huntington’s Disease Movement.”

I aim to study how key facets of the movement intertwined with major developments in the biotechnological and medical revolutions of the past 200 years. I believe that the HD cause can serve as a guidepost for other disease communities and inform key bioethical questions related to them.

I also want to help the HD community reflect on its path through history. 

More than ever, my scholarly work and HD advocacy will meld. (Click here to read more.)

Seeing our daughter enter college

On a personal level, good health allowed me to join my wife Regina last August in helping our HD-free daughter Bianca set up for her first semester at the University of Pennsylvania, where she is studying in its College of Arts and Sciences.

I had always feared that HD would prevent me from experiencing this special moment – just as HD had stopped my mother from interacting with Bianca as a baby and young child.

I am more determined than ever to see Bianca graduate from college and find her way in life. I’m hoping that GENERATION HD1, the historic Roche Phase 3 clinical trial of a gene-silencing HD drug, will result in an effective treatment not only for patients, but as a preventive measure for presymptomatic gene carriers like me. Roche hopes to enroll the first volunteers starting in early 2019.

Looking ahead, I hope to retire on my own timeline – not because of HD.

The preciousness of life

I’ve been extremely fortunate to reach this point without HD symptoms—or other significant health problems. Many HD brothers and sisters of my generation are struggling with symptoms. 

Like so many in HD families and other difficult situations, I’ve learned to value each moment of life.

Others face different health issues. At this time last year, I lost two wonderful friends about my age, generous supporters of the HD cause, taken quickly and unexpectedly by other conditions. I’ve missed them dearly, and think about them daily as a reminder of the preciousness of life.

Tomorrow, I want to enjoy Thanksgiving.

God and nature willing, I’ll awake the next day ready to love my family, continue the fight to defeat HD, and dream of a day when a cure frees me to assist people less fortunate.

Happy Thanksgiving! And the best of health for you and yours.

This Thanksgiving, let’s show gratitude for disease researchers and drug hunters

This Thanksgiving, let’s pause to show gratitude for the many researchers and drug developers in America and around the world who strive to treat diseases and improve the quality of health for all.

As we await the first effective treatment for one of the world’s cruelest maladies, we in the Huntington’s disease community feel especially grateful for the efforts of the scientific, medical, and biotech communities to bring relief from HD’s devastating cognitive, motor, and behavioral symptoms.

Our cause is urgent: HD strikes in the prime of life and is ultimately fatal. Stopping HD would mark a historic step in the quest to conquer brain diseases.

As a presymptomatic carrier of the HD gene, I found inspiration for Thanksgiving 2016 in the powerful speech last February by HD advocates Astri Arnesen and Svein Olaf Olsen at the 11th Annual HD Therapeutics Conference, sponsored by CHDI Foundation, Inc.

Leaders of the HD cause in their native Norway and in the European Huntington Association (EHA), this indomitable couple bared their souls about marital commitment, denial, genetic testing, and raising a family.

Their goal: to motivate – and demonstrate appreciation for – the audience of more than 200 world-class HD researchers, physicians, and drug company executives.

‘No questions asked’

Astri and Svein Olaf titled their presentation “HD – more than a disease!”

“HD is much more than a disease,” Astri said leading off. “It affects every part of your life, and it’s really a part of who you are.”

Astri’s family traced back HD to a maternal great-grandmother. Her maternal grandfather and her mother also developed the disease.

However, as is so often the case in HD, nobody in Astri’s family discussed the condition, even though they witnessed relatives’ debilitating symptoms each day.

“You just sensed: no questions should be asked,” Astri explained. “My mother grew up in this family.”

A special education teacher, Astri in the 1980s fell in love with a co-worker, Svein Olaf. She divorced her husband – a brief marriage she had entered to escape caring for her HD-stricken mother – and started a relationship with Svein Olaf.

‘The greatest gift of all’

Svein Olaf knew of Astri’s 50-50 chance of carrying the HD gene. However, the young couple didn’t discuss HD much. Without Astri getting tested, they had two daughters in the early 1990s, before the discovery of the huntingtin gene in 1993 and the development of a definitive genetic test.

After their older daughter Jannike turned 18 in 2009, she wanted to get tested for HD.

“I said to her, ‘That’s not possible,’” Astri said. “‘I could not by any means let you go through that. I will do the test [first].’ So the day before Christmas, I called the doctor.”

The process took weeks. The waiting and uncertainty were so traumatic, Svein Olaf told the audience, that afterwards he could not “remember anything about the tests. Nothing.”

When the couple visited the clinic to obtain the results, the doctor practically came running to Astri. “You don’t have the gene!” she exclaimed.

Svein Olaf crashed his hand on a table. At that moment, he vowed to marry Astri, something they had planned for years but always put off.

“It was really the most amazing thing to come home and tell our daughters that there is no risk anymore,” Astri remembered. “That was really for me the most important thing. You can handle your own situation, but knowing that I hadn’t passed it on to them was really the greatest gift of all.”

The hope of science

Since then the couple have dedicated themselves to the HD cause – in part because Astri’s youngest sibling, Arne Dag, was stricken with HD.

“He was a brilliant young man,” Astri said. “He was really teaching my father, an engineer, how to fix the car when he was six years old. So he was a future engineer coming up. But in his early 20s, he’s starting to have trouble. He doesn’t manage to finish his studies.”

In a typical symptom of HD, Arne Dag became deeply depressed. He was formally diagnosed in 2005.

At the 2010 meeting of the European Medicines Agency (the counterpart of the U.S. Food and Drug Administration) in London, Astri showed a video of a short interview she did with her brother.

In the clip, Arne Dag struggles to speak, and his body twists and turns because of chorea, the involuntary movements caused by HD.

Arne Dag tells Astri that he wants to participate in a clinical trial as soon as possible. She asks him about his hopes for the future.

“I hope that science is on my side,” he says, laughing.

Thanking the researchers

Arne Dag died in April 2015 at the age of 46.

“But he hoped,” Astri told the conference attendees. “And that was really important in his life. He hoped for the hard work you [scientists] are doing to give results for him and for us.”

As a slide showing infants appeared in the background, she added: “And that’s what we are fighting for, and that’s why we are so involved in this work. Because now, it’s not about him. It’s not about me. It’s about all these lovely children and grown-ups living with a risk, living with the gene, and who really put their hope on you and your work.

“And no matter how long it takes, that is so important in our daily lives. Knowing that you go to work really makes our day easier. For me, hope has really been my way of coping and dealing with it, and it is for a lot of us. We are many, many out there who support you, who need you, and who are waiting for results.

“So we want to thank you so much. It’s amazing to see how many fantastic, brilliant researchers that are in this field. We are so grateful for that.”

Happy Thanksgiving!
