UK families create buyers club for cut-price cystic fibrosis drug

Parents of children with cystic fibrosis who are desperate to use a drug that the NHScannot afford are forming a buyers club to obtain a cut-price version made in Argentinawhere the patent does not apply.
Angry at the stalemate between Vertex, the US manufacturer of Orkambi, and NHSEngland, the families are forming the club to help each other through the legal and technical hurdles of importing the cheaper generic drugs for each child’s individual needs.
The concept was central to the Hollywood film Dallas Buyers Club, which was based on the real situation of people who could not obtain drugs for their HIV infections in the 1980s and 90s.
Orkambi’s list price is £104,000 per patient per year, which the NHS has said is unaffordable. Negotiations broke down last July. After an outcry this year triggered a health select committee hearing and a meeting between the health secretary, Matt Hancock, and Vertex’s chief executive, Jeff Leiden, the company returned to the negotiating table, but there is no sign of a deal.
Orkambi is the first drug to treat the underlying causes of cystic fibrosis, a progressive disease in which mucus clogs up the lungs. Infections cause lasting damage and early death. There are 10,400 patients with cystic fibrosis in the UK, 40% of whom could benefit from Orkambi, the brand name of a drug made from the chemical compounds ivacaftor and lumacaftor. The drug is more effective the earlier it is given in the course of the disease.
The Argentinian generic, made by Gador and called Lucaftor, costs 70%-80% less than Vertex’s list price, which four families in the UK have paid for privately. However, the generic drug costs more than £20,000 for a year’s supply, which will still be unaffordable for many.
The families are calling on the government to override Vertex’s patent and buy the generic drug for all those who need it. About 120 families in Argentina use Lucaftor, which has been certified as equivalent to Orkambi.
One of the parents, Robert Finlay (not his real name), went to a meeting with a representative of Gador in London. “To hold a box of it in my hand after trying to fight for this was really quite emotional,” he said. His daughter, Florence, seven, is well at the moment, but he knows of another child her age who is not. “Since last autumn she has lost 40% of her lung function. In the last six months she has been in hospital on intravenous antibiotics.”
Florence has recently picked up a bug. “It is another course of antibiotics for the next three weeks as a precaution,” Finlay said. “The sooner she takes Orkambi, the less damage will be done.”
Rob Long has been buying Orkambi from Vertex for his son Aidan, nine, since last June. “He was in good shape but obviously it is about keeping him in good shape – halting the decline, basically,” he said.
Aidan did well on the drug, growing taller and gaining weight. But after the trampolining champion fell and broke both arms last September, Long said he was glad Aidan was on the drug because he was unable to do the physiotherapy that all cystic fibrosis patients have to undergo to keep their lungs free of sticky mucus.
It was Long who found Gador. He said he was paying for Orkambi “because my son’s health is paramount”, and that everybody who needed it should have access to it. He started to search online and via social media for a cheaper generic version as soon as Orkambi was approved in Europe for children of his son’s age, in February 2018. “I couldn’t rest until I had explored every angle,” he said.
Eventually a Colombian told him about a version made in Argentina. He said he was sceptical and cautious at first, but in April he was able to share the news with other parents. “They were very excited,” he said.
Parents have been campaigning for access to Orkambi since it was licensed nearly four years ago. Last summer Vertex rejected an NHS England offer of £500m over five years and potentially £1bn over 10 years for access to Orkambi and other cystic fibrosis drugs in the pipeline.
NHSEngland recently revealed it had made a further offer, to include an increased price for Orkambi and another drug, Kalydeco, which the NHS already provides but which works for only a small number of people. It proposed a two-year managed access scheme, which would allow the NHS to collect data on how well the drugs work. The prices would then be revised up or down. Vertex made another offer this week, well above what the NHS is willing to pay.
Long, Finlay and others argue that the UK government could make the generic drug available on the NHS by using the crown use provisions of UK patent law which allows a patent to be disregarded in the national interest. Another option would be to launch a large-scale trial for cystic fibrosis patients in which it would be legal to use the generic drug, as the NHS has done with drugs to protect men at risk of HIV infection.
Long is worried Vertex will call on Donald Trump to intervene. Vertex has a history of political lobbying and the US government has always defended US pharmaceutical company patents. “The UK is looking for a trade deal and we are off to buy generics,” said Long. “A lot of politicians will back off very quickly.”
Meanwhile, families who say time is not on their side will attempt to find the money to buy Lucaftor themselves, which can legally be shipped from Argentina directly to individual patients in three-monthly packages. Some are likely to try to raise funds for the treatment online.
Vertex said it was committed to finding a way to provide access to Orkambi and its other drugs for all eligible cystic fibrosis patients in England. “We have been open to discussing multiple options and flexibilities which would allow cystic fibrosis patients to access currently approved medicines,” a spokesperson said.
They said the list price of £104,000 should not be interpreted as the offer to NHSEngland. “Companies who claim to be able to produce a product similar to Orkambi have not had to bear the cost of drug discovery and development; though it should be noted that even at a 70%-80% cost reduction from the list price, this is still higher than the amount NHS England offered to pay for Orkambi in 2018.”
A Department of Health and Social Care spokesperson said: “It is absolutely right that patients should have access to cost-effective, innovative medicines on the NHS at a price we can afford. Our approach remains to urge Vertex to accept NHS England’s generous offer.”

High-Deductible Plans and Breast Cancer: Not What You Want to See

Diagnosis made nearly 7 months later than for women in low-deductible plans

High-deductible health plans (HDHPs) were linked to delays in diagnosis and treatment for breast cancer among low-income women, J. Frank Wharam, MD, said here at the AcademyHealth Annual Research Meeting.
High-deductible health plans — in which patients pay lower premiums than traditional health plans but pay deductibles ranging anywhere from $1,000 to $7,000 before coverage kicks in — are becoming an increasingly larger part of the health insurance landscape, Wharam noted. “Between 2006 and 2018, HDHPs grew to [cover] almost 60% of workers,” he said. The researchers decided to look at breast cancer care for patients with HDHPs because breast cancer is a relatively common condition, affecting 12% of women at some point during their lifetime. They focused on women living in rural areas because rural residents generally have an increased risk for delayed cancer care, leading to adverse outcomes and worse mortality, said Wharam, of the Harvard Pilgrim Health Care Institute, in Boston. Their findings were also published in Health Affairs.
“Low-income women in HDHPs experienced relative delays of 1.6 months to first breast imaging, 2.7 months to first biopsy, 6.6 months to incident early-stage breast cancer diagnosis, and 8.7 months to first chemotherapy,” compared with their counterparts in low-deductible plans, the group said in the Health Affairs paper. All these delays were statistically significant.
He and his colleagues analyzed data on some 1.5 million individuals with commercial insurance who had enrolled from Jan. 1, 2003 through Dec. 31, 2014, including about 130,000 with HDHPs. Wharam’s group was particularly interested in those whose employers switched coverage plans from low-deductible plans — $500 or less — to HDHPs with deductibles of $1,000 or more. The study sample included about 32,000 women ages 25–64 in HDHPs who did not have evidence of breast cancer before the study started; they were compared with a control group of about 255,000 women whose employers kept low-deductible plans.
The mean age of both groups of women was 45. A total of 75% of women in the HDHP group were low-income, compared with 73% of controls. Similarly, 14% of women in an HDHP had low levels of education, compared with 13% of controls. Eighty-one percent of women in both groups were white; 3% in the HDHP group were Hispanic compared with 4% of controls.
“Rural women in HDHPs experienced substantial delays across the arc of cancer care, from diagnostic testing to treatment,” said Wharam. “Adding high out-of-pocket costs to preexisting barriers might cause especially pronounced ‘financial toxicity’ among rural women.”
The researchers also looked at data on higher-income women and found that those who were switched to HDHPs waited less than a month longer for diagnostic breast imaging than women with low deductibles, and 1.9 months longer for a breast biopsy. In addition, among high-income women, time to incident early-stage breast cancer diagnosis was 5.4 months longer among HDHP members compared to women with low deductibles, and time to first chemotherapy was 5.7 months longer, the investigators wrote in Health Affairs.
Study limitations included the observational design that left a potential for unmeasured confounding; also, dropout occurred during the follow-up period, and results apply only to women with commercial health insurance.
“We believe further research is needed to determine if these delays cause adverse health outcomes; we’re trying to work on that now,” Wharam said. “Physicians and their teams should closely monitor rural women in HDHPs who are at risk for breast cancer. We believe these results speak to [the] need for population tailored commercial health insurance designs where out-of-pocket costs are lowered for certain at-risk populations. This could facilitate transitions through these phases of breast cancer care.”
The study was funded by the National Cancer Institute. Wharam declared no relevant financial interests.

Home exercise program reduces rate of falling in at-risk seniors

An in-home exercise program reduced subsequent falls in high-risk seniors by 36 per cent, according the results of a 12-month clinical trial published today in the Journal of the American Medical Association.
The study, conducted by UBC faculty of medicine researchers in partnership with the clinical team at the Falls Prevention Clinic at Vancouver General Hospital, found a reduction in fall rate and a small improvement in cognitive function in seniors who received strength and balance training through the clinical trial.
“When we think about falls we often think about loss of muscle strength and poor balance,” said Dr. Teresa Liu-Ambrose, principal investigator at the Vancouver Coastal Health Research Institute and professor in the department of physical therapy at the University of British Columbia. “However, the ability to remain upright and not fall is also dependent on cognitive abilities–calculating how far to lift your foot to get over a curb, making a decision as to when to cross the road, and paying attention to your physical environment while you are having a conversation.”
Falls increase risk of injury and loss of independence for older adults. Exercise is a widely recommended fall prevention strategy, but whether it can reduce subsequent falls in those who have previously fallen is not well established.
The study involved 344 adults aged 70 and older who had been referred to the Falls Prevention Clinic following a fall that had resulted in a visit to a medical facility, such as an emergency room. Participants had a history of falls, with an average of three prior falls per person, and generally had symptoms of frailty and limited mobility.
The study had participants perform a set of balance and resistance training exercises in the comfort of their homes, using simple equipment such as free weights, a minimum of three times per week. Over the course of six months, a physical therapist made five home visits to prescribe exercises and ensure that exercises were done properly. For those who completed the program, the results were notable. Participants were less likely to experience repeat falls, and as a secondary benefit, they improved in some markers of cognitive function.
Falls in older adults are the third-leading cause of chronic disability. According to the Public Health Agency of Canada, 20 to 30 per cent of Canadian seniors suffer falls each year, and falls are the leading cause of hospitalization for adults over age 65.
“It is well known that exercise benefits older people in general, but what was special about this study group was that they are at very high risk for losing their independence–they had both mobility and cognitive impairments and another fall may mean the inability to live in their own homes. Many already had difficulty navigating public spaces independently,” said Liu-Ambrose, who holds a Canada Research Chair in Physical Activity, Mobility, and Cognitive Neuroscience.
“Older adults who experience falls that require medical attention falls are medically complex and at high risk for both morbidity and mortality, and we demonstrated that exercise is a practical and cost-effective intervention that can improve older peoples’ outcomes after a significant fall,” she added.
Liu-Ambrose and her team at the Centre for Hip Health and Mobility are now looking at whether the exercise program resulted in reduced health care utilization and medical cost savings in this high-risk population.

Allena Announces Interim Results from Kidney Disorder Med Study

— Substantial Treatment Effect Observed in Patients with Enteric Hyperoxaluria, Including Robust Reductions in Both Urine and Plasma Oxalate 
— Reloxaliase Well-Tolerated Over 12 Weeks of Dosing 
— Detailed Results to be Presented at OHF International Hyperoxaluria Workshop in June 2019 —
Allena Pharmaceuticals, Inc. (NASDAQ: ALNA), a late-stage, biopharmaceutical company dedicated to developing and commercializing first-in-class, oral enzyme therapeutics to treat patients with rare and severe metabolic and kidney disorders, today announced interim data from Study 206, its Phase 2 basket clinical trial of reloxaliase, an orally-administered, recombinant oxalate-degrading enzyme. Study 206 includes adult and pediatric patients suffering from the progression of primary hyperoxaluria (PH) or enteric hyperoxaluria (EH) with advanced chronic kidney disease (CKD), both of which can lead to systemic oxalosis, a potentially life-threating condition. Consistent with Allena’s prior clinical experience, EH patients treated with reloxaliase in Study 206 demonstrated a substantial treatment effect.  This includes EH patients with advanced CKD, a patient population not previously treated with reloxaliase, who showed reductions in urine oxalate (UOx) and plasma oxalate (POx). Allena plans to present detailed results at the OHF International Hyperoxaluria Workshop, June 21-22, 2019 in Boston, MA.
“We are pleased to see a robust response to reloxaliase in EH patients suffering from advanced stages of the disease. We believe this reflects reloxaliase’s activity and novel mechanism of action of degrading oxalate within the GI tract, which is well-targeted to treat excess oxalate absorption driven by an underlying GI disorder. The potential to alleviate the high oxalate burden on these patients is very encouraging,” said Louis Brenner, M.D., President and Chief Executive Officer of Allena Pharmaceuticals. “To our knowledge, this is a first demonstration of a specific pharmacologic therapy leading to reduction in plasma oxalate and urinary oxalate levels in patients with EH and decreased kidney function, which represents a significant advancement for the field and especially for patients with systemic oxalosis. These results advance our efforts to develop reloxaliase as a potential first-in-class therapy for patients with enteric hyperoxaluria, and we look forward to additional data from Study 206, as well as topline data from our pivotal Phase 3 URIROX-1 trial, anticipated in the second half of the year.”

Continued Peanut Allergy Therapy Spurs Greater Tolerance, Data Shows

As Aimmune Therapeutics awaits potential regulatory approval of its peanut allergy treatment, the company released additional data that showed an extension of daily therapy with its experimental AR101 asset significantly improved tolerability to peanut allergies.
Aimmune announced results from ARC004, an open-label, rollover study of the landmark Phase III PALISADE trial that showed an extension of daily therapy with AR101 by an additional 28 weeks improved tolerability with lower numbers of adverse events compared to the PALISADE therapeutic dosing period. Initial Phase III data showed treatment with the AR101 peanut allergy therapy was effective in more than 67% of juvenile patients. At the time the trial data was released, Aimmune said the patients administered AR101 in the PALISADE trial could tolerate exposure of at least a 600-mg dose of peanut protein in the exit food challenge. Only 4% of patients on the placebo could tolerate that amount, the company said when the late-stage data was released.
The latest data though, presented at the European Academy of Allergy and Clinical Immunology Congress 2019 in Lisbon, shows that longer treatment with AR101 provides even greater protection. The study showed that 79.8% of patients who continued taking AR101, an oral biologic desensitization therapy that is sprinkled over food before eating, could tolerate doses of at least 1,000 mg of peanut protein. Nearly half, 49%, of the patients, tolerated the highest 2,000 mg dose during the exit food challenge. Patients enrolled in the study continued to see meaningful immunological changes, reinforcing the potential benefits of continued daily AR101 dosing after one year, Aimmune said.

“These findings demonstrate that AR101 treatment extended into the second year reduces adverse events, increases ability the ability to tolerate even high levels of exposure to peanut protein over time, and further modulates the immune response to peanut in most patients,” said Daniel Adelman, Aimmune’s chief medical officer, said in a statement.
Adelman added that the results of the extended study should provide some peace of mind to patients with peanut allergy and their families.
Approximately 2.5% of all children in the U.S. may be allergic to peanuts. It is one of the most common food allergies. According to the American College of Allergy, Asthma and Immunology, the incidence of peanut allergies in children in the U.S. has risen about 21% since 2010.
A U.S. Food and Drug Administration advisory committee is expected to weigh in on Aimmune’s peanut allergy treatment in September. The FDA accepted the BLA for AR101 in March 2019 and previously informed Aimmune that completion of its review would be targeted by late January 2020. AR101 was granted Fast Track designation from the FDA.
Last year, in anticipation of the likely approval of AR101, NestlĂ© increased its stake in the company. The nearly $100 million investment gave the conglomerate a 19% ownership of Aimmune. NestlĂ© first pumped $145 million into the company in 2016 and then another $30 million as part of its initial public offering last year.
