Can we afford the costs of orphan disease treatments?

Millions of people in America suffer from rare, or “orphan,” diseases, conditions defined by the government as affecting fewer than 200,000 people. With an estimated 30,000 affected individuals, Huntington’s disease is one of the more common of these disorders.

The pharmaceutical industry has largely ignored these diseases, which number several thousand, because each disease promises too few customers/patients to enable companies to recoup investments in drug research and development and therefore generate a profit. The market usually doesn’t work for people with these diseases.

News about a lawsuit by Arkansas cystic fibrosis (CF) patients against the state’s Medicaid program for its refusal to pay for a highly effective but extremely expensive drug – Vertex Pharmaceutical’s Kalydeco – shined light on this predicament.

In an article titled “The $300,000 Drug,” New York Times columnist Joe Nocera recognized Kalydeco as a “wonder drug” but questioned whether the country can afford the personalized medicine approach that enables scientists to design specialized treatments for very small and specific groups of patients.

With an annual wholesale cost of $311,000, Kalydeco was developed for a subgroup of about 1,100 CF patients with specific genetic mutations. The subgroup numbers about 2,150 patients worldwide in an overall CF population of 70,000 individuals.

“Because patients will likely be taking the drug for the rest of their lives, it could cost millions of dollars to keep just one patient on Kalydeco,” Nocera speculated. “That raises another important question about the coming of personalized medicine. How are we, as a society, going to pay for it?”

Same question for the HD community

The HD community could face this very same question. Because the U.S. has only 30,000 HD patients and 150,000 to 250,000 people at risk of carrying the gene, a potential treatment could cost a lot.

Boston-headquartered Vertex has sought to develop HD treatments since mid-2008. Though the company has made a substantial effort, it doesn’t yet have plans for a clinical trial. (Click here to read more.) Isis Pharmaceuticals, Inc., of Carlsbad, CA, has also worked about as long and is planning to launch a clinical trial in the next year or two.

It’s still too early to project the costs of treatments that have yet to be tested or even fully designed. Other potential remedies are in trials but at best likely remain years from reaching the market.

Furthermore, an HD treatment regimen will likely involve a cocktail of remedies, meaning that patients – via their insurers – will probably have to pay for more than one drug.

Patient assistance programs

The HD community must remain vigilant regarding the cost of potential treatments. However, failing to consider a number of factors, the coverage of the Kalydeco costs was perhaps too pessimistic about the future.

First, as I commented regarding the impatience with California’s stem cell institute after ten years of operation without a drug, biomedical research is slow by nature. And it’s expensive, with the average cost of developing a new drug in the U.S. at $1.2 billion. Only one in ten clinical trials results in a marketable drug, although the research from the unsuccessful projects provides highly valuable information on what does not work.

In the case of CF, Vertex is at work on another treatment that would reach thousands more patients with different kinds of mutations.

As Nocera himself noted, Vertex provides Kalydeco for free to patients without insurance.

Lundbeck, the pharmaceutical firm that markets Xenazine, which diminishes some of the involuntary movements caused by HD (chorea), provides financial assistance to patients who qualify. Depending on the dosage, the annual wholesale cost of this treatment can reach $50,000 or more, but, according to the Lundbeck website, “85 percent of U.S. patients taking Xenazine have a monthly co-pay of $50 or less before requesting co-pay assistance.”

It’s highly conceivable that the developers of future HD treatments will provide similar kinds of assistance – especially because these firms will have relied on the good will and extensive cooperation of HD families who participate in research studies and clinical trials. However, it’s not clear what the drug companies will charge insurers.

CHDI and pharma giants

After the founding in 2003 of the CHDI Foundation, Inc., a non-profit virtual biotech firm backed by wealthy donors who wish to remain anonymous, pharmaceutical firms small and large started to gain interest in developing Huntington’s treatments.

As a result, the network of firms working on HD now includes pharmaceutical giants such as Pfizer, Roche, and Medtronic.

As a non-profit with the sole purpose of finding HD treatments, CHDI promotes research on Huntington’s and the diffusion of scientific knowledge about the disease. With more researchers and firms involved, the chances for treatments have grown. Having more options could very well mean that treatments would cost less.

By pouring hundreds of millions of dollars into HD drug research, CHDI has created an incentive to produce cheaper drugs.

As it states on its website, CHDI seeks to connect academic research, drug discovery, and clinical development in order to avoid “costly delays to therapeutic development” and make potential treatments a “good investment” that will result in “full clinical development, including licensure and marketing to get drugs to HD patients.”

Similarly, the Hereditary Disease Foundation and the Huntington’s Disease Society of America (HDSA) have supported research that could yield yet additional drugs.

Patient-driven medicine

Thanks to this level of support for HD research, the HD community stands in perhaps a better position than those facing even more rare diseases.

Nevertheless, orphan disease communities in general have reason to feel optimistic about both the development of treatments and their cost, if the vision of one key medical leader becomes reality.

Lee Hood, M.D., Ph.D., one of the scientific giants behind the Genome Project and the recipient in 1987 of the Lasker Basic Medical Research Award (the American equivalent of the Nobel Prize), has developed a plan for more effective and affordable medicine. In 2000, Dr. Hood founded the Institute for Systems Biology (ISB). Located in Seattle, the non-profit ISB teams scientists and technologists from many disciplines to pioneer the future of research in biology, biotechnology, medicine, environmental science, and science education.

In a 2012 speech at the Seventh Annual HD Therapeutics Conference, sponsored by CHDI, Dr. Hood outlined the importance of systems biology – what I think of as the “big picture” of disease – for HD research. Dr. Hood also advocated for the adoption of P4 medicine: predictive, preventive, personalized, and participatory. (Click here to read more.)

“Patients and consumers will be a major driver in the realization of P4 medicine through their participation in medically oriented social networks directed at improving their own healthcare,” Dr. Hood and Mauricio Flores, J.D., wrote in the March 2012 issue of the journal New Biotechnology.

ISB and several collaborating organizations have run some pilot programs in P4. If it is implemented on a wide scale, Dr. Hood predicts that it will revolutionize our healthcare system. Everybody will carry a health-monitoring device, and diseases will be predicted and prevented long before onset as the result of tiny blood samples taken from a pin prick, the article states.

Predicting falling medical costs

Significantly, costs could plummet.

“P4 medicine will require that all healthcare companies rewrite their business plans in the next 10 years or so,” Dr. Hood and Flores wrote. “Many will not be able to do so and will become ‘industrial dinosaurs.’ There will be enormous economic opportunities for the emergence of new companies tailored to the needs and opportunities of P4 medicine.”

The authors projected that savings will result from a series of factors, including earlier and more effective diagnosis of disease; better matching of drugs with diseases and their subtypes; better identification of genetically based adverse reactions to drugs; the ability to “re-engineer” disease-affected biological networks within people in order to reduce the cost of drug development; an increasing ability to deal effectively with cancer; the use of stem cells for replacement therapy and diagnostics; the routine extension of effective mental and physical health into people’s 80s and 90s; an improved understanding of microbes in the body; a deeper understanding of neurodegeneration (the cause of HD, Alzheimer’s, Parkinson’s, and other disorders); and the digitalization of medical and genetic information.

“On another tact, our prediction is that there will be a ‘wellness industry’ that will emerge over the next 10-15 years that will in time far exceed the size of the healthcare industry,” Dr. Hood and Flores affirmed. “P4 medicine is an area replete with economic opportunities.”

Dr. Hood and Flores believe that P4 medicine will “democratize” healthcare.

“The patient (consumer), through social networks, will drive the emergence of P4 medicine,” they wrote. “Because of intrinsic conservatism and sclerotic bureaucratic systems, physicians, healthcare specialists and the healthcare industry will take a back seat to the power of patient-driven social networks in bringing change to the healthcare system. Indeed, patients may be the only driving force capable of truly changing our contemporary healthcare system to the proactive P4 mode.”

This scenario serves as a serious alternative to the dim view that orphan disease communities will remain relegated to high-cost solutions.

Guaranteeing proper care standards

Indeed, a “revolution” has occurred over the past two decades in how patients have related to their doctors and the pharmaceutical industry (click here to read more).

Nowadays, people enter the healthcare system as both patients and advocates for their well-being.

This outlook led the Arkansas patients to sue for the right to have their Kalydeco costs covered.

Their lawsuit offers a striking similarity with the HD community’s pressure on the Social Security Administration and Congress to update the decades-old, inaccurate government criteria for determining disability benefits for Huntington’s patients (click here to read more). The Arkansas plaintiffs in effect have demanded that the state recognize Kalydeco as the standard treatment for their type of CF.

Negotiating the price

The competition of the marketplace, greater efficiency in drug development, and the revolution in medicine outlined by Dr. Hood should put downward pressure on the cost of drugs.

Patient advocates must play a crucial role in this process.

As the late San Diego biotech leader Duane Roth had told me during a dinner with California stem cell leaders in 2008, patient advocates must find ways to appeal to pharmaceutical companies’ primary interest in profits. Advocates need to lobby and court these business leaders.

At the same time, disease organizations such as HDSA and its network of advocates can pressure pharmaceutical companies and government agencies to assure new drugs’ accessibility and affordability.

In some circumstances, government can join in the process of persuasion and even play hardball, as the Brazilian Ministry of Health did in the 1990s in order to convince multinational pharmaceutical firms to dramatically reduce the price of HIV/AIDS medications. The Brazilian government provides HIV/AIDS drugs for free.

“Local production of generics, the possibility of breaking patents, and the offer of technology transfer became instruments for price negotiations with other countries and the pharmaceutical industry, leading to a real reduction in prices on the Brazilian and international markets,” wrote the coordinator of the country’s National STD/AIDS Program.

The marketplace exists, but it is susceptible to politics.

The rhetoric about the $300,000 drug can scare a lot of people. But in the long run, such a cost is not a foregone conclusion.

The Team Hope Walk: reinforcing the first line of defense against Huntington’s disease

In the fight against Huntington’s disease, hope begins at home.

That’s the message I took away from yesterday’s inaugural Team Hope Walk of the San Diego Chapter of the Huntington’s Disease Society of America (HDSA-San Diego) after my family’s team traversed the 3.1 mile route. It was the first time my wife, my eleven-year-old daughter, and I participated together in an HDSA event.

We walked to honor the memory of my mother, who succumbed to HD in 2006 at the age of 68, and my father, her “HD warrior” caregiver, who died with a broken heart in 2009.

Civic leaders Allan and Jane Rappoport, long-time supporters of HDSA-San Diego, joined our team. They are close friends and our daughter’s surrogate grandparents – an especially important relationship because her lone surviving grandparent lives in Brazil.

Below I’ve posted our team picture, another family milestone: it’s the first time I’m presenting a photo of my wife and daughter to the readers of this blog. I’m taking one more big step out of the “HD closet,” a long and emotionally trying process that began almost two years ago with my first public speeches about my family’s struggle with HD.

So often eroded by the fear, stigma, and denial that accompany HD, such togetherness at the starting line provides the love and strength that sustain families in the long, arduous journey with this fatal disorder.

The Team Hope Walk held special significance for me because I am gene-positive for Huntington’s. At 52, I have reached the age of my mother’s onset. Each moment without symptoms is a precious gift – and a beautiful reminder of how our daughter tested negative and can thrive as she approaches adolescence.

As I walked alongside my family and friends, I felt protected by my family and the Rappoports. All of us renewed our hopes that researchers would soon find effective therapies for HD.

Striking a balance between elite and grassroots events

In all, 34 teams and more than 200 walkers took part in the event.

In the 1990s and early 2000s HDSA focused on simple, family- and community-based events such as hoop-a-thons and walks. However, as the organization grew along with the demand for research dollars in the quest for therapies, its emphasis shifted towards elite fundraisers such as galas with expensive tickets and pricey auction items. In this respect, HDSA-San Diego excelled, bringing in several hundred thousand dollars some years with signature events such as the Celebration of Hope Gala and the Shoot to Cure HD.

For financial or health reasons, HD people and their families often couldn’t participate in the signature events.

Responding to grassroots accusations of aloofness and recognizing the need to draw families into the organization, HDSA now seeks to strike a better balance between big fundraisers and community-oriented events. (For background on HDSA issues, please click here. You can also learn more by listening to Melissa Biliardi’s March 27, 2012, interview with HDSA CEO Louise Vetter by clicking here.)

Since the inception of Team Hope in 2007, the walks have spread to 80 cities across the country. HDSA reports that these events have raised more than $3 million.

Bringing families under the umbrella

Yesterday’s San Diego walk raised nearly $30,000, well above the goal of $25,000. Presenting sponsor Vertex Pharmaceuticals donated $2,500, recruited a team of nearly 50 walkers, and staged a pre-event fundraiser at its San Diego facility. Elmcroft Senior Living also donated $2,500 and set up a large team. Elite Security contributed with an additional 48 walkers. A number of local businesses supported the event with gifts of raffle items, food, and supplies, and the Lawrence Family Jewish Community Center (JCC) provided tables, equipment, and other items.

Lundbeck, the title sponsor of the Team Hope Walks program, has provided a substantial educational assistance grant to HDSA at the national level.

Nan Pace, a JCC manager, served as event co-coordinator along with health researcher Misty Oto. Both women serve on the HDSA-San Diego board.

“The importance of this walk was to give Huntington’s disease families in San Diego an opportunity to express themselves not only visually but through their families, by contacting them and letting them know that there will be fundraising and also bringing awareness to a very important cause,” said Oto. “It was so surprising to see new families that we haven’t been in touch with create First Giving pages, fundraise, and participate. Now we have new families that are under the umbrella of HDSA because of this event.”

The dream of participation

“This is the very first time that San Diego has offered an event that all people of all abilities could participate in,” Oto added. “All of our events have been centered on marathons, bike rides, and races that were a little bit longer, and where someone with Huntington’s could not participate or someone who had a family member with Huntington’s felt that the fundraising goals were a little bit out of reach.”

Registrants paid just $25 to participate.

For HD-affected individuals who could not walk the course, HD activist Silvia Gonzalez provided a ride on her three-wheeled motorcycle.

“That was such a huge thing, because not only did they get to participate in the event, but they got to live out the dream of riding on a motorcycle,” Oto pointed out.

Local HD families “know that they have a voice, that we are paying attention,” continued Oto, whose mother died of HD several years ago. Oto tested negative for HD but has a number of affected relatives.

HDSA has “struggled” with the need to strike a balance between research and families, Oto suggested. The Team Hope Walk “unified in one cause” three key aspects of its mission: research, fundraising, and awareness.

Preparing for the challenges ahead

The San Diego Team Hope Walk brought out the very large extended Huntington’s disease family of this metropolitan area: HD people, asymptomatic gene-positive individuals like me, gene-negative HD family members, other family members, friends, corporate and local business sponsors, and key players in the search for therapies such as Vertex and Lundbeck.

I believe that, with the proper planning and exposure, the Team Hope Walks can help inform and galvanize the HD community for a major challenge as researchers ramp up to clinical trials for potential therapies: recruitment of individuals for research studies and clinical trials.

Without such participation, scientists cannot test potential remedies for safety and efficacy, thus delaying or even preventing the arrival of treatments.

Ultimately, Team Hope involves families in the fight against HD. Families are the first line of defense – and the seed of hope.

No time for complacency: get ready for HD clinical trials

In the past few years, scientists have made huge strides towards treating and perhaps even controlling Huntington’s disease, whose killer gene inhabits every cell of my body. While scientists scrupulously avoid providing false hope, even the most pessimistic among them now talk of “when” a treatment or treatments will come, not “if,” as international HD spokesperson Charles Sabine observed last October at the annual Huntington’s Study Group conference in San Diego, CA.

That’s enormous progress, compared to a decade ago, when practically no pharmaceutical companies showed interest in HD.

But this is no time for complacency. On the contrary, as labs ramp up for potential clinical trials to test the first group of the 700-plus potential “drug targets” for HD, many daunting challenges and tasks remain.

I plan to deliver this message in a speech this coming Saturday, July 30, at the 2011 Inaugural Clinical Research Symposium of the Northwest Chapter of the Huntington’s Disease Society of America (HDSA) at Evergreen Hospital Medical Center in Seattle, WA (click here for the program). The speech will be titled “What HD Families Should Know about Clinical Trials: Initial Thoughts from a Gene-Positive Activist.”

The clinical trial administrators will need a large number of symptomatic people to participate, ranging from 20 to as many as a couple thousand people per drug. With only 30,000 people in the entire U.S. affected by HD, it may prove impossible to fill the numerous spots in the trials.

That is why CHDI Foundation, Inc., the so-called “cure Huntington’s disease initiative,” has inaugurated Enroll-HD, the first-ever worldwide database of at-risk, gene-positive, and HD-affected people, in order to expand the base of possible trial participants.

All must chip in

As advocates like Charles and me have pointed out, those active in organizations such as the Huntington’s Disease Society of America (HDSA) can no longer limit our focus to fund-raising. At-risk, gene-positive, and affected people must also collaborate with the researchers and physicians in the process of planning and implementing the trials.

Preparing for potential trials requires that we care for our health as much as possible.

And, as I wrote in 2009, the untested in our community, who constitute a majority of the at-risk, need to muster the courage to learn their status. With the hope of treatments, refusing testing makes less and less sense. And, if people don’t get tested, they can’t participate in a trial.

In short, if we all don’t chip in, treatments won’t be found.

The painful barrier of denial

Chances are, if you read this blog, you already agree with this outlook. You’re probably active in the HD effort in some way. So, as they say, I’m preaching to the choir.

We need to reach out to those in the community who shun involvement, usually out of fear, and sometimes out of ignorance.

I know all too painfully how denial works.

My mother Carol died of HD in 2006 after battling HD for nearly two decades. Her at-risk, untested brother and his wife hid the truth about her disease from their children and their families by attributing Mom’s symptoms to “mental problems.”

A split family

I am also estranged from my own sister, the untested mother of three at-risk, untested adult sons whom she conceived before my mother’s diagnosis. She prefers to do nothing, because she does not believe, or is unaware, that there is hope. She is completely uninterested in advocacy, research, and trials.

As a gene-positive activist, I personify the knife-edge of HD for my family. My sister became especially uncooperative after the birth of our “miracle baby,” who tested negative in the womb. My sister was jealous for two reasons: we had a daughter, and she was HD-free.

In reading this description of my own family, many will knowingly nod in agreement. Denial is powerful, and it is everywhere. Combined with the sorrow, frustration, anger, and fear provoked by HD, it splits families apart.

I have fought back against the threat of HD by participating in numerous observational trials and advocating for the cause.

But I have yet to figure out a way to involve family members so deeply in denial – and so angry at me whenever I raised the issue of HD, directly or indirectly.

Living by example

As Charles observed, it will be truly tragic if people are not ready for clinical trials.

But we must not give up. Through this blog and my activism I have met many people new to HD and looking for ways to help. We need to welcome these individuals and their families with the greatest of attention – and love.

And we must live by example, because, in the end, our actions will carry far more weight than our words.

Defining success together

The HD community also can participate actively in the clinical trial process by helping researchers, physicians, drug makers, and the federal Food and Drug Administration (FDA) define a successful drug and how to measure that success.

HD causes a triad of symptoms: motor (shaking known as chorea and problems with coordination), cognitive (memory and mental abilities), and psychiatric (emotional disturbances). For a long time, scientists have spoken of the need for a “cocktail” of drugs to combat the triad and their numerous causes in the brain and brain cells.

So far, only one HD drug – tetrabenazine – has received FDA approval. Marketed by Lundbeck as Xenazine, this medication reduces chorea but does not affect the causes of HD.

The new generation of drug targets would indeed attack the causes. Researchers and drug makers theorize and hope that these targets would improve or perhaps even eliminate particular symptoms, but many of these new kinds of drugs represent uncharted scientific territory. Until the trials get underway, nobody will know how patients will respond.

So, even before trials start, patients must help define specific outcomes for the trials.

Maintaining functionality and personality

During the question-and-answer session after my May 17, 2011, speech at Alnylam Pharmaceuticals, I outlined what I thought were signs of success.

“From my standpoint, wow, maybe I will never have symptoms of Huntington’s disease,” I said in reflecting on the proposed Alnylam RNA interference drug, intended to attack the disease at its genetic roots and possibly ready for a Phase I trial as early as 2012. “That would be my hope as a patient.

“For the longest time, it’s like, ‘Well, you’re going to get sick.’ The question is: ‘When are you going to get sick? And how sick are you going to get? And what can you take to stop it?’…

That response came from my individual perspective as a gene-positive, asymptomatic individual – what the scientists refer to as the “presymptomatic” stage of HD.

But I also gave my opinion as to what symptomatic HD patients might want from a drug. I thought of my mother, who had been reduced to a “mere shadow of herself.”

We need drugs that will help people maintain their “basic functionality” and personalities. A bit of chorea would probably be acceptable as long as a person retains his or her mind and can go to work, I said.

“People want to keep their personality with this disease,” I said. “They want to be recognized as individuals. They don’t want to be seen as sick; they don’t want to be seen as drunk; they don’t want to be seen as disabled individuals.”

But I’m just one voice. More people need to give their opinions on this still very open question.

Strengthening the patient-researcher bond

As is often the case, I have only just scratched the surface of one of the many issues surrounding Huntington’s disease.

It’s clear that we all need to educate ourselves about the kinds of medicines under consideration and how they might affect the disease.

I hope to do my small part at the Seattle symposium. Across the country, our community needs more events such as this.

But in addition to speaking, I want to brainstorm with the audience about the definition of pharmaceutical success and absorb the other speakers’ ideas about clinical trials.

The HD community has a long reputation as one in which patients and researchers collaborate effectively. Now, as we get ready for historic clinical trials, we need to further strengthen that crucial bond.
