Proteostasis Gains After Cystic Fibrosis Drug Is Granted Orphan Status

Micro-cap biotech Proteostasis Therapeutics Inc PTI 4.67% was up strongly Tuesday morning.

What Happened

Proteostasis, which focuses on therapies for dysfunctional protein processing, specifically for cystic fibrosis, announced Tuesday its PTI-428 has been granted orphan drug designation, or ODD, by the European Commission, for treating cystic fibrosis.
PTI-428 is the Boston-based biotech’s lead product candidate. It’s the company’s proprietary cystic fibrosis transmembrane conductance regulatory amplifier in clinical development.
The pipeline asset has also secured ODD, Breakthrough Therapy Designation and Fast Track Designation from the U.S. Food And Drug Administration.

Why It’s Important

Orphan drug designation is granted by the EU based on a positive opinion by the EMA’s Committee’s Orphan Medical Products, bestowing regulatory and financial incentives for companies developing therapies to treat serious disorders affecting no more than five in 10,000 persons in the EU.
The notable among the benefits are 10-year market exclusivity in the EU upon approval, eligibility for protocol assistance, reduced fees and access to the EU’s centralized marketing authorization procedure.

What Next

Proteostasis said it will advance PTI-428 in the clinic later this year, as part of the planned 28-day Phase 2 studies of its proprietary combination CFTR modulator treatments.

Gene mutation evolved to cope with modern high-sugar diets

A common gene mutation helps people cope with modern diets by keeping blood sugar low, but close to half of people still have an older variant that may be better suited to prehistoric diets, finds a new study.
The gene variant became more common in humans after cooking and farming became widespread, and might now help people avoid diabetes, according to the findings published in eLife.
“We found that people differ in how efficiently their bodies can manage blood sugar levels, resulting from an evolutionary process that seems to have been brought about by changing diets,” said the study’s lead author, Professor Frances Brodsky, Director of UCL Biosciences.
The researchers were investigating the CLTCL1 gene, which directs production of the CHC22 protein that plays a key role in regulating a glucose transporter in our fat and muscle cells.
After people eat, the hormone insulin reacts to higher levels of blood glucose by releasing the transporter to remove glucose from the blood, taking it into muscle and fat tissue. Between meals, with the help of the CHC22 protein, the glucose transporter remains inside muscle and fat so that some blood sugar will continue to circulate.
The research team, consisting of specialists in population genetics, evolutionary biology, ancient DNA and cell biology, analysed human genomes as well as those of 61 other species, to understand how the gene producing CHC22 has varied throughout evolutionary history.
In humans, by looking at the genomes of 2,504 people from the global 1000 Genomes Project, they found that almost half of the people in many ethnic groups have a variant of CHC22 that is produced by a mutated gene, which became more common as people developed cooking and farming.
The researchers also looked at genomes of ancient humans, and found that the newer variant is more common in ancient and modern farming populations than in hunter-gatherers, suggesting that increased consumption of carbohydrates could have been the selective force driving the genetic adaptation.
By studying cells, the researchers found that the newer CHC22 variant is less effective at keeping the glucose transporter inside muscle and fat between meals, meaning the transporter can more readily clear glucose out of the blood. People with the newer variant will therefore have lower blood sugar.
“The older version of this genetic variant likely would have been helpful to our ancestors as it would have helped maintain higher levels of blood sugar during periods of fasting, in times when we didn’t have such easy access to carbohydrates, and this would have helped us evolve our large brains,” said first author Dr Matteo Fumagalli, who began the study at UCL before moving to Imperial College London.
“In more recent years, with our high-carb diets that often provide us too much sugar, the newer variant may be advantageous,” Dr Fumagalli added.
The researchers say that while this genetic variant does not play a direct role in the development of diabetes, having the older variant may make people more likely to develop diabetes, and it may also exacerbate insulin resistance involved in diabetes.
“People with the older variant may need to be more careful of their carb intake, but more research is needed to understand how the genetic variant we found can impact our physiology,” added Professor Brodsky.
Co-author Professor Mark Thomas (UCL Genetics, Evolution & Environment) added: “Our analyses strongly suggest that we have found yet another example of how prehistoric changes in dietary habits have shaped human evolution. Understanding how we have adapted to these changes doesn’t only inform us about why people lived or died in the past, but also helps us to better understand the relationship between diet, health and disease today.”
The study was funded by the National Institutes of Health (USA), Wellcome and the Medical Research Council (UK).

Quest, Now LabCorp, Customers Hit in Collections Firm Breach

Medical testing giant LabCorp. said today personal and financial data on some 7.7 million consumers were exposed by a breach at a third-party billing collections firm. That third party — the American Medical Collection Agency (AMCA) — also recently notified competing firm Quest Diagnostics that an intrusion in its payments Web site exposed personal, financial and medical data on nearly 12 million Quest patients.
Just a few days ago, the news was all about how Quest had suffered a major breach. But today’s disclosure by LabCorp. suggests we are nowhere near done hearing about other companies with millions of consumers victimized because of this incident: The AMCA is a New York company with a storied history of aggressively collecting debt for a broad range of businesses, including medical labs and hospitals, direct marketers, telecom companies, and state and local traffic/toll agencies.
In a filing today with the U.S. Securities and Exchange Commission, LabCorp. said it learned that the breach at AMCA persisted between Aug. 1, 2018 and March 30, 2019. It said the information exposed could include first and last name, date of birth, address, phone, date of service, provider, and balance information.
“AMCA’s affected system also included credit card or bank account information that was provided by the consumer to AMCA (for those who sought to pay their balance),” the filing reads. “LabCorp provided no ordered test, laboratory results, or diagnostic information to AMCA. AMCA has advised LabCorp that Social Security Numbers and insurance identification information are not stored or maintained for LabCorp consumers.”
LabCorp further said the AMCA has informed LabCorp “it is in the process of sending notices to approximately 200,000 LabCorp consumers whose credit card or bank account information may have been accessed. AMCA has not yet provided LabCorp a list of the affected LabCorp consumers or more specific information about them.”
The LabCorp disclosure comes just days after competing lab testing firm Quest Diagnostics disclosed that the hack of AMCA exposed the personal, financial and medical data on approximately 11.9 million patients.
Quest said it first heard from the AMCA about the breach on May 14, but that it wasn’t until two weeks later that AMCA disclosed the number of patients affected and what information was accessed, which includes financial information (e.g., credit card numbers and bank account information), medical information and Social Security Numbers.
Quest says it has since stopped doing business with the AMCA and has hired a security firm to investigate the incident. Much like LabCorp, Quest also alleges the AMCA still hasn’t said which 11.9 million patients were impacted and that the company was withholding information about the incident.
The AMCA declined to comment for this story, and instead referred requests for comment to an outside PR firm. Representatives with that firm declined to answer any questions about whether the breach of the AMCA’s payment’s page impacted anyone who entered payment data into the company’s site during the breach.
“We are investigating a data incident involving an unauthorized user accessing the American Medical Collection Agency system,” reads a written statement attributed to the ACMA. “Upon receiving information from a security compliance firm that works with credit card companies of a possible security compromise, we conducted an internal review, and then took down our web payments page.”
The statement continues:
“We hired a third-party external forensics firm to investigate any potential security breach in our systems, migrated our web payments portal services to a third-party vendor, and retained additional experts to advise on, and implement, steps to increase our systems’ security. We have also advised law enforcement of this incident. We remain committed to our system’s security, data privacy, and the protection of personal information.”

ANALYSIS

The AMCA also does business under the name “Retrieval-Masters Credit Bureau,” a company that has been in business since 1977. Retrieval-Masters also has an atrocious reputation for allegedly harassing consumers for debts they never owed.
A search on the company’s name at the complaints page of the Consumer Financial Protection Bureau (CFPB) turns up almost 700 complaints for Retrieval-Masters. The company has an abysmal “F” rating from the Better Business Bureau, with 60 complaints closed against it in the last three years.
Reviewing a number of those complaints reveals some of the AMCA’s other current and/or previous clients, including New Jersey’s EZPass system. Recent consumer complaints about the AMCA also invoke the name of American Traffic Solutions, which services rental car fleets and processes some 50 million toll transactions per year. ATS did not respond to requests for comment.
My guess is we will soon hear about many other companies and millions more consumers impacted by this breach at the AMCA. Certainly, companies like Quest and LabCorp. have a duty to ensure contractors are properly safeguarding their patients’ personal, medical and financial information.
But this AMCA incident is the latest example of a breach at a little-known company that nevertheless holds vast quantities of sensitive data that was being shared or stored in ways that were beyond the control of affected consumers.
On May 24, KrebsOnSecurity broke the news that the Web site for Fortune 500 real estate title insurance giant First American Financial [NYSE:FAF] leaked 885 million documents related to mortgage deals going back to 2003, until notified by KrebsOnSecurity. The digitized records — including bank account numbers and statements, mortgage and tax records, Social Security numbers, wire transaction receipts, and drivers license images — were available without authentication to anyone with a Web browser.
Many readers wrote in to say they’d never heard of First American, but it is the largest title insurance company in the United States. Title insurance is generally required for all home mortgages, and it protects the buyer from any previously unknown claims against the property. First American currently handles about one in every four title insurance transactions — usually as part of the mortgage closing process — which means tens of millions of Americans were potentially exposed by the company’s inexplicably lax security.

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.
