Tough news for Huntington’s, other neurological disease patients: Roche halts dosing in historic clinical trial on signs of inefficacy

 

Calling it “tough news to share” and “even more difficult to receive,” pharmaceutical giant Roche announced on March 22 that it has halted dosing in the firm’s historic Phase 3 Huntington's disease clinical trial of its gene silencing drug tominersen, GENERATION HD1, because of unfavorable efficacy data, as seen by an independent review committee.

 

“The committee recently met for a pre-planned review of the latest safety and efficacy data from GENERATION HD1 and made a recommendation about the investigational therapy’s potential benefit/risk profile,” wrote David West, Roche’s senior director, for Global Patient Partnership, in a letter addressed to the international HD community. “Based on the committee’s recommendation, we will permanently stop dosing with tominersen and placebo in the GENERATION HD1 study.”

 

GENERATION HD1 began in early 2019, paused for several months to recalibrate dosing, and became fully enrolled in April 2020. Volunteers were to receive the drug over 25 months, and Roche had expected to finish the trial and report results in 2022. Tominersen developer Ionis Pharmaceuticals, Inc., Roche’s partner, had completed a Phase 1/2a trial of the drug (testing for mainly safety and tolerability) in 2017. That trial was so successful that Roche skipped a full-blown Phase 2 and went directly to Phase 3, GENERATION HD1.

 

West noted that the review committee’s recommendations resulted not from “any new emergent safety concern, but on a broad assessment of the benefit/risk” for those receiving the drug as compared to those getting the placebo.

 

This means that the drug demonstrated an “unfavorable efficacy trend,” an official of U.S. Roche’s subsidiary Genentech wrote me in an e-mail. If successful, the trial would have demonstrated that tominersen could slow, halt, or even reverse HD symptoms.

 

“This is brutal and I am absolutely devastated for our patients and families,” Jody Corey-Bloom, M.D., Ph.D., the director of the Huntington’s Disease Society of America (HDSA) Center of Excellence at the University of California, San Diego, wrote me.

 

Trial participants in Dr. Corey-Bloom’s clinic were among those taking part in GENERATION HD1. “I am glad that Roche will continue following patients for safety and clinical outcomes,” she added.

 

Veteran HD physician LaVonne Goodman expressed a similar sentiment. “Hope has been so very high for this drug; our community will feel not just disappointment, but real grief,” Dr. Goodman wrote me. “However, we’re accustomed to grief, and are resilient.  I think part of the community message should be that supporting each other is vitally important now.”

 

HDSA Chief Scientific Officer George Yohrling, Ph.D., called the news “devastating.” “HD families around the world had their hopes held high that this experimental drug could one day soon become an effective therapy for HD,” Dr. Yohrling stated. “While this is clearly not the news we wanted to hear, I am confident that in the coming weeks the Generation HD1 data will help the scientific community understand why tominersen did not meet its desired outcome.”

 

Robert Pacifici, Ph.D., the chief scientific officer for CHDI Foundation, Inc., the nonprofit virtual biotech dedicated to discovering HD therapies and a collaborator of Roche and Ionis, also commented on the development.

 

“Roche’s decision to discontinue dosing in most of its Huntington’s disease studies based on a recommendation from the unblinded [with access to data] Independent Data Monitoring Committee that periodically reviews study data is a very disappointing outcome,” Dr. Pacifici wrote. “However, knowing our colleagues at Roche we are confident that this decision has been made in good faith with the best interests of study participants uppermost in mind.”

 

 

No new safety concern caused the halt

 

The stop to the Roche trial underscores the fact that an effective treatment still eludes not only HD scientists, but also researchers of Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis (ALS), and other neurological conditions.

 

The reviewers who recommended the halt to GENERATION HD1 work separately from Roche. The committee has not yet shared its specific reasoning or data with Roche.

 

“It is important to note that the recommendation is not based on any new emergent safety concern,” West’s letter stated.

 

Roche has notified the clinical trial sites in the 18 participating countries of the halt. The sites are contacting the 791 symptomatic volunteers who had enrolled in the program.

 

The participants were receiving intrathecal (spinal) injections of tominersen or a placebo. Participants in GEN-EXTEND (an extension study for participants coming from any Roche HD study) will also no longer receive doses.

 

“It is our intention to provide as much information as we can to the community, which at this time is limited until we have accessed and analyzed full data,” West’s letter explained.

 

West acknowledged “the tremendous contribution of the families who are participating in these studies, as well as the broader Huntington’s community for their collaboration.”

 

Next steps depend on the data

 

Although Roche has stopped giving tominersen to the volunteers, the trial has not yet ended.

 

“The studies will remain ongoing (without further dosing in GENERATION HD1 and GEN-EXTEND) and it is intended that study participants will be followed by their physicians for safety and clinical outcomes,” West stated. Roche has not provided a timeline for the remainder of the work to be completed.

 

A Q&A appended to West’s letter states that “Roche remains committed to the HD space and our studies are continuing,” and data from GENERATION HD1 “will advance our understanding of tominersen and inform research for other disease modifying treatments.” It adds: “In addition to tominersen, the Roche family of companies is investigating gene therapy approaches to treating Huntington’s disease.”

 

The conclusions about GENERATION HD1 – and possible next steps by Roche and Ionis­­ – will depend on the analysis of the independent reviewers’ explanations and all of the massive data from the Phase 3 trial.

 

As Dr. Pacifici noted, only when data from the independent review committee has been “shared with the wider HD community” will it become possible to “form a scientific opinion” about the halting of the trial.

 

A perplexing result

 

Ionis held a public conference call on March 22 to answer questions about the Roche announcement.

 

“This is the largest Huntington’s trial ever conducted,” stated Ionis CEO Brett Monia, Ph.D. “It was conducted on a wealth of information.”

 

Monia stated that, “while we are saddened by today’s outcome, we are committed to the HD community and focused on delivering treatments for this and other devastating neurological diseases.”

 

Monia added, “Although this is a disappointing setback for Ionis and the HD community, we are confident in the potential of our technology platform to address many neurological diseases.”

 

Various questioners on the call asked Dr. Monia and Ionis scientists to speculate about the reasons for the halt and future potential approaches using the company’s technology (antisense oligonucleotides, or ASOs), but the Ionis officials emphasized that answers are premature without access to the data.

 

“We are still strong believers in the ASO approach,” Dr. Monia asserted.

 

However, Ionis Chief Scientific Officer Frank Bennett, Ph.D., the long-time coordinator of the firm’s HD program, added that the news of the potential ineffectiveness of using an ASO to reduce the amount of huntingtin protein in patients was “perplexing and disappointing to us,” leaving many unanswered questions.

 

Eric Swayze, Ph.D., Ionis’s executive vice president for research and one of the developers of the ASO, reminded the participants on the call of a fundamental reality of HD: “It’s a complex disease.”

 

Dr. Monia added that “one silver lining” in the halt to GENERATION HD1 was that it did not, as noted above, result from a concern about safety.

 

Diversification necessary

 

Although the pioneering Roche-Ionis program had electrified the HD world with the hope of the first effective treatment, the HD research community has also deliberately diversified the approaches to treating HD.

 

Thus, companies like Triplet Therapeutics, Inc. have leveraged publicly available knowledge gained from the Roche/Ionis program and others to plan their own, unique drug development strategies.

 

Triplet aims to start a clinical trial in the second half of this year for a potential drug targeted at stopping the mutant huntingtin gene’s tendency for continued expansion with age. That expansion compromises brain cells and triggers disease. In this respect, HD is known as a repeat expansion disorder (RED), with the triplets of the genetic code CAG recurring too many times and thus causing disease.

 

As a Triplet scientist explained last year, the Roche/Ionis approach is like “putting a brake” on the disease, whereas Triplet’s ASO will target the expansion of the gene and therefore seek to “remove the foot on the gas.” (Click here to read more).

 

Using the same mechanism, in addition to HD, Triplet hopes to develop transformative treatments for many of the more than 50 other REDs. For REDs of the central nervous system, it would use the same drug as for Huntington’s.

 

Although unavailable for comment on the Roche announcement, Triplet executives offered encouragement in an e-mail to me: “Triplet’s thoughts are with the HD community, and our clinical development plans in HD and other repeat expansion disorders remain on track and unchanged.”

 

As one scientist wrote me (and as I also felt), the Roche announcement was like a punch to the gut. However, I am also heartened by the potential of other clinical trials like Triplet’s. (I will further explore the implications of the Roche trial halt in upcoming articles.)

 

To echo Dr. Goodman’s words, our community and its scientists are indeed resilient.

Chief Huntington’s disease drug hunter: ‘every confidence first treatments’ in the works

Surveying the vast progress in Huntington’s disease research and a “blitz” of clinical trials now in progress, a key scientific leader in the efforts has predicted that they will produce treatments for the incurable neurological disorder.

“I have every confidence that this batch of clinical candidates that are now being tested are going to yield the first treatments for Huntington’s,” said Robert Pacifici, Ph.D., the chief scientific officer for CHDI, the multi-million-dollar non-profit virtual HD biotech.

Dr. Pacifici’s remarks came in an interview on February 24 in Palm Springs, CA, at the organization’s 11th Annual HD Therapeutics Conference, sponsored by CHDI Foundation, Inc., the backer of the initiative.

Nobody can foretell the result of a clinical trial, and Dr. Pacifici did not specify a timeline for an effective treatment reaching the market. However, he offered examples of the immense progress towards developing treatments.

“It’s really frustrating for people, I know, to say, ‘That’s good news, that’s good news, but where’s the treatment, where are the drugs?’” Dr. Pacifici said. “The thing I would point to is that so many of the things we said were going to happen actually have happened. And so many of the things that have happened have actually yielded the outcome that we wanted.”

Dr. Pacifici cited three recent key advances: the ongoing research in biomarkers (signals) to measure the efficacy of potential drugs’ in reducing the harmful presence of abnormal huntingtin protein in brain cells; major progress in identifying modifier genes that delay or hasten disease onset; and the start of clinical trials.

The trials post the most “difficult” challenge in the process, he said.

“We want to make sure that we do things in a way that obviously is very careful,” he said, explaining the primacy of drug safety. “The last thing we want to do is harm anybody.”

Noting that the search for drugs has no guarantees, Dr. Pacifici nevertheless concluded that these are “exciting times” for the community of HD families, researchers, and supporters of the cause.

First Ionis patients safe

Until recent years, such good news seemed like a remote possibility for HD Therapeutics Conference participants and, indeed, for the entire HD community.

Because of the growing number of HD clinical trials and therefore greater hope for effective treatments, Dr. Pacifici and fellow CHDI conference organizers launched a new feature at this year’s conference, the “Clinical Trials Update Blitz.” Representatives from four different trials presented their latest news in 15-minute presentations.

The most anticipated update focused on the historic trial by Ionis Pharmaceuticals, Inc., to attack the root cause of HD via gene-silencing.

Trial principal investigator Sarah Tabrizi, M.D., Ph.D., of University College London reported that all patients in the very first cohort in the Phase 1b/2a trial – aimed at testing primarily safety and tolerability – completed the trial without incident.

The first group of participants received the first dosing of the drug, IONIS-RTT_RX, in October 2015. They received three additional doses at 28-day intervals and were monitored by trial administrators.

“We completed Cohort A, in London and Vancouver, four subjects, and the DSMB [independent data safety monitoring review board] met and allowed us to move to cohort B,” Dr. Tabrizi said. (A DSMB, a standard in all clinical trials, halts a study if patient safety is threatened.)

Administrators of the Ionis trial are currently recruiting volunteers for Cohort B, to be followed by Cohorts C and D, as outlined in the plans for the experiment. In all, 36 patients will take part in Phase 1b/2a. If all cohorts are successful, Ionis will seek approval for a full-blown, larger Phase 2 trial to test drug efficacy.

For further background on the trial, watch Dr. Tabrizi’s update in the video below.

More than a disease

Drawing a record 325 participants from academia, the pharmaceutical business, and the medical field, the conference highlighted cutting-edge HD research, including the structure and function of the huntingtin protein; the huntingtin gene and the human genome; potential gene-silencing treatments; restoration of cell health; and ways to measure clinical trial outcomes.

Although highly dedicated to HD research, many of the non-physician scientists have little if any contact with HD families. This has prompted CHDI to open each conference with a keynote by a representative of the HD community to drive home the human reality of the disease and the urgent need for treatments. (I keynoted the 2011 meeting.)

This year Astri Arnesen and Svein Olaf Olsen, a married couple who have led the HD cause in their native Norway and in the European Huntington Association, delivered a powerful keynote about HD and marital commitment, denial, genetic testing, and raising a family. They titled their presentation “HD – more than a disease!”

Astri and Svein Olaf received a standing ovation.

I will explore their story and provide an overview of the key scientific findings in a second report on the conference.

An upbeat mood

As in past years, the CHDI meeting moved me profoundly.

I identified with the many difficult feelings and experiences recounted by Astri and Svein Olaf.

Once again, the scientists’ presentations reminded me of HD’s devastation of the brain – and of my vulnerability as a carrier of the HD mutation.

But this was a very upbeat conference. I had never spoken before to Dr. Tabrizi, but we hugged as if we were old friends after I congratulated her on the initial clinical trial report. The HD community has waited so long for such news!

Later, after I worked late into the evening on this article and missed the buffet dinner, Jerry Turner, the CHDI staffer in charge of conference logistics, arranged for a care plate of sumptuous leftovers from the kitchen of the Parker hotel, the gracious host of the conference.

I toasted to the success of the Ionis clinical trial and to CHDI’s commitment to the project with Doug Macdonald, Ph.D., CHDI’s director of drug discovery and development and its point man on gene-silencing.

As I told another scientist, I look forward to the day when we can all toast the discovery of an effective treatment.

The little things that are really big: caregiving in families with Huntington’s disease

The everyday kindness of the back roads more than makes up for the agony of the headlines – Charles Kuralt

As a member of a Huntington’s disease family, I have become deeply familiar with the common yet often unheralded human practice of caregiving.

My “HD warrior” father Paul Serbin cared for my HD-stricken mother Carol for more than a decade.

My mother died ten years ago this week. Her passing sent me into a months-long dual spiral of anxiety and depression: I had inherited the HD gene from her, and seeing her demise provided a portent of my own future (click here to read more).

Because of the inevitability of HD onset, I know that I too will require caregiving.

Furthermore, as a father, I’ve spent the past fifteen years helping my wife Regina raise our daughter Bianca, a special form of caregiving. Bianca tested negative in the womb, thus avoiding the specter of juvenile Huntington’s. As we teach her to drive and begin discussions about college, our role as parents becomes both more rewarding yet more complex.

Three weeks ago, the balance shifted, as Bianca and I became temporary caregivers for Regina: she underwent an operation to repair a torn rotator cuff and must keep her right arm in a sling for at least six weeks.

Completely interdependent

Caregiving is about all of the little – but really big – things we humans do for each other.

It’s how families, hospitals, and nursing homes run.

We are completely interdependent.

As we’ve helped Regina over the past several weeks, the meaning of caregiving has become ever more clear to me.

It involves small but important tasks: bathing her, spraying on deodorant, buttoning her shirt, adjusting her sling, driving her to doctor’s and physical therapy appointments, taking over her share of car pool duties, providing assistance in the kitchen, exercising her disabled arm – these and many more tasks have highlighted for me the importance of caregiving, taught me to be more sensitive to Regina’s needs, and reminded me of what’s most important in life.

Despite a busy high school life, Bianca has helped out, too.

It’s brought us closer together.

Valid and important emotions

I’m certainly no saint. I’ve done my share of grumbling! And sometimes I feel overwhelmed.

As I’ve learned from news items posted on Facebook HD discussion pages, caregiving experts say it’s okay to experience feelings associated with caregiving such as anger, boredom, frustration, and impatience.

“Whether you become a caregiver gradually or all of sudden due to a crisis, or whether you are a caregiver willingly or by default, many emotions surface when you take on the job of caregiving,” a recent article at Dementia Today states. “Some of these feelings happen right away and some don’t surface until you have been caregiving for awhile. Whatever your situation, it is important to remember that you, too, are important. All of your emotions, good and bad, about caregiving are not only allowed, but valid and important.”

As another article suggests, caregivers need to face emotions directly, find healthy ways to release anger, share feelings with close friends, and take breaks to pursue enjoyment.

These recommendations can apply to short-term caregiving situations such as recovery from an operation but also to long-term situations involving HD, Alzheimer’s disease, and other afflictions.

Overlooked and undervalued

Until my mother went into a nursing home in the final months of her life, my father cared for my mother’s daily needs with the assistance of a professional caregiver who visited their home a few hours each week. He helped her in the bathroom, fed her, and pushed her wheelchair.

She was the love of his life. He was stubborn about accepting more help at home and getting her physical therapy, but each day he climbed with her into the HD trenches.

Not once did I hear him complain. Maybe he should have!

In our celebritocracy, such dedication goes unrecognized. Each year family caregivers are estimated to provide the equivalent of nearly half a trillion dollars in unpaid care.

In America, care and caregiving are “overlooked and undervalued,” writes Zachary White, Ph.D., the author of the blog The Unprepared Caregiver.

Unlike highly valued, professional jobs, informal caregiving isn’t considered a career.

“Parents and relatives and friends won’t be able to brag about your experiences.” Dr. White writes. “There are no ‘schools’ of informal caregiving – no Harvard or Stanford to use as a guiding goal from which others can respect and admire. Others may speak highly of your role and your efforts, but it begins and ends there.”

While taking care of loved ones, members of the HD and other neurological disease communities have long advocated for better caregiver assistance and nursing home care – including disease-specific instruction for health aides. These will remain daunting challenges for the foreseeable future.

Preemptive caregiving

I believe that Regina’s devotion to me and our family is a big reason why I’ve passed my mother’s age of HD onset. She helps provide for the family by working as a full-time elementary school teacher; she sees to it that Bianca and I eat healthily; and she supports my HD advocacy.

She has done a lot of preemptive caregiving.

Caring for Regina during her recovery and remembering my mother’s struggles with Huntington’s have led me to reflect on my future caregiving needs.

As I race against the genetic clock and await the development of treatments for this incurable disorder and a health care system more responsive to those with brain diseases, I want to avoid becoming a burden on my family.

By maintaining good health in the present, I can perhaps reduce that future burden.

However, I know that, for each HD family, this is uncharted territory. We can forge ahead by caring for our our family members – and for the larger community.

Defeating Huntington’s disease starts with taking care of yourself and joining Enroll-HD

For those of us affected by Huntington’s disease or at risk for it, the fight against the disorder begins by taking care of ourselves.

This idea occurred to me during my daily morning meditation on Jan. 14, 2016, as I anticipated my annual checkup in the Enroll-HD program later that day.

Many people struggling to come to terms with HD ask: with so much to worry about, how can I contribute to the cause?

You can start simply by committing to care for your health and asking family members and others to help monitor your condition. In doing so, you will help your family, too, by preparing for and perhaps even diminishing the current or eventual caregiving burden associated with Huntington’s.

You can extend that assistance to the entire HD community by joining Enroll-HD, a worldwide registry of affected individuals, asymptomatic HD gene carriers, untested at-risk individuals, and other family members. With its growing database, Enroll-HD serves as a platform and research project aimed at facilitating clinical trials and the discovery of treatments.

The greater the participation in Enroll-HD, the faster trials can take place.

Helping the researchers

Not long after learning of my own risk for HD in 1995, I started participating in research projects based at the University of California, San Diego (UCSD), and San Diego State University (SDSU) (click here to read about one example).

In January 2015, shortly after my participation in the PREDICT-HD study ended, I registered in Enroll-HD.

At this month’s follow-up visit at the UCSD Huntington’s Disease Clinical Research Center, I once again gave blood that scientists can use in the numerous research projects facilitated by Enroll-HD. I also underwent a battery of cognitive tests.

In addition, I participated in four research projects by scientists at UCSD, SDSU, and other local institutions. Two involved standing on high-tech platforms designed to detect  balance problems in people who have brain disorders and concussions. Another involved a measure of fine motor skills, which are seriously affected in HD, by writing on a special tablet connected to a computer.

Finally, I spit into a tiny collection tube for a project involving the detection and study of the huntingtin protein in saliva. Abnormal huntingtin causes HD.

A neurological exam

My visit concluded with a standard neurological exam by Jody Corey-Bloom, M.D., Ph.D., the director of the UCSD clinic. Among other tasks, I had to follow her fingers with my eyes, rapidly tap together my thumb with my index and middle fingers, and walk down a straight line for about 25 feet.

To my great relief, Dr. Corey-Bloom noted no irregularities! At 56, I am now past the point at which my HD-stricken mother displayed the characteristic involuntary movements.

Afterwards, I discussed with Dr. Corey-Bloom my questions and concerns about my potential participation in the SIGNAL clinical trial to test a monoclonal antibody as an HD treatment.

I will soon provide an update on SIGNAL.

Enroll-HD’s positive impact

The next day, I obtained the latest news about Enroll-HD from Joe Giuliano, the director of clinical operations for CHDI, the multi-million-dollar nonprofit virtual biotech aimed exclusively at developing HD treatments. In collaboration with HD research centers and clinics around the globe, CHDI sponsors Enroll-HD.

Enroll-HD officially launched in July 2012. According to Giuliano, as of January 15, nearly 9,000 individuals from 14 countries and 140 sites had signed up.

Has the program met CHDI’s expectations?

“I think there’s a high level of engagement among the patient community and among the investigators around the world,” he said during a phone interview. “The recruitment has been excellent. We could have 10,000 participants by the end of March, which would be amazing. I’m really pleased with how well the availability of the dataset and the biological samples [blood] has worked out. In other words, people are using the data, and the data is available through the website. It’s a great example of making data available quickly.”

What’s been the impact?

“We’ve been actively assisting three clinical trials that have been going on – PRIDE, Amaryllis, and LEGATO – with their recruitment,” Giuliano continued. “We have released our second periodic dataset, with 4,150 participants. There are 28 projects that are currently using Enroll-HD data, to answer different research questions. We’ve been actively distributing biological samples for a variety of projects.”

As a result of Enroll-HD, scientists are deepening their understanding of the disease, and doctors are finding ways to improve care.

Enroll-HD contributes directly to the quest for treatments. The larger the number of potential clinical trial volunteers, the greater the chance that trial administrators can enlist the required number for each trial. The number of HD trials has increased each year, increasing the demand for volunteers. Without the trials and the volunteers, scientists can’t test treatments.

Challenges in Latin America

On the downside, in one key region, Latin America, Enroll-HD has progressed “very slowly,” Giuliano said. So far, Enroll-HD is only operating in Argentina and Chile.

In October 2015, the National Research Ethics Commission in Brazil – the world’s sixth largest nation, with an estimated 20,000 HD-affected individuals – rejected the proposal to set up Enroll-HD there.

“Obviously we were very disappointed,” Giuliano said. “I think the National Research Ethics Commission rejected based on some areas where there was a perception that the Enroll-HD study was not aligned well with some of Brazil’s legal precedents.”

However, Giuliano said that Enroll-HD will step up efforts to involve Latin America’s HD families. With growing interest in Colombia, that country be the next to join Enroll-HD, he said.

“We’re working harder than ever,” Giuliano affirmed. “You haven’t heard the end of us in Brazil. We’re really committed to Latin America. Many of us believe that Latin America, like in the beginning of their history of HD research in Venezuela, which played an important role – now in the later stages of HD research it’s going to resurge, reawaken, and become an important player in HD research again.”

In a future article I will explore the Brazil decision in depth as well as ways HD families can push for greater acceptance of Enroll-HD there and in other countries of the region.

Building a common cause

As I approach the inevitable onset of HD and feel many of the other effects of normal aging, I realize more than ever the need to stay in shape via a healthy diet, daily stretching and aerobics, meditation and spirituality, and psychotherapy.

Without health, I cannot work, dedicate myself to my family, or advocate for the HD cause.

Caregivers, the "HD warriors" who enter the trenches each day, must also seek opportunities for respite.

With the significant progress towards HD treatments of recent years and growing awareness of the importance of HD and other neurological disorders, advocates have a busier agenda than ever.

I am thrilled to assist HD research and the implementation of the critical clinical trials by taking part in Enroll-HD.

After following the HD movement in Brazil for two decades and participating in the historic sixth World Congress on Huntington’s Disease there in September 2013, I aim to join my Brazilian HD brothers and sisters to advocate for reconsideration of the government’s rejection of Enroll-HD.

We must not lose the momentum in Brazil and Latin America!

Only by building this common cause can we ultimately defeat HD.
