    FDA decision expected by July 5, 2015 PDUFA date

    Approximately 8,500 people with cystic fibrosis in the U.S. have two copies of the F508del mutation and are ages 12 and
    older

    BOSTON–(BUSINESS WIRE)– Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that the U.S. Food and Drug Administration’s (FDA) Pulmonary-Allergy Drugs Advisory Committee (PADAC) voted 12 to 1 to recommend that the FDA approve ORKAMBITM (lumacaftor/ivacaftor) for use in people with cystic fibrosis (CF) ages 12 and older who have two copies of the F508del mutation in the CFTR gene. Advisory committees provide the FDA with independent scientific and medical advice on safety, effectiveness and appropriate use of potential new medicines. The FDA is expected to make a decision on the approval of ORKAMBI by July 5, 2015 under the Prescription Drug User Fee Act (PDUFA). The FDA is not bound by the committee’s recommendation but often follows its advice. If approved, ORKAMBI will be the first and only medicine to treat the underlying cause of CF for eligible people with CF ages 12 and older with two copies of the F508del mutation in the CFTR gene. People with two copies of the F508del mutation represent the largest group of people with CF. There are approximately 8,500 people ages 12 and older with two copies of the F508del mutation in the U.S.

    “Today’s positive recommendation brings the cystic fibrosis community one step closer to potential approval of the first medicine to treat the underlying cause of this disease for many more people,” said Jeffrey Chodakewitz, M.D., Executive Vice President and Chief Medical Officer at Vertex. “We look forward to continuing to work with the FDA and other regulatory agencies throughout the world to make ORKAMBI available to eligible patients as soon as possible.”

    Cystic fibrosis is a rare genetic disease that is caused by defective or missing CFTR proteins resulting from mutations in the CFTR gene. The defective or missing proteins result in poor flow of salt and water into and out of the cell in a number of organs, including the lungs. In people with two copies of the F508del mutation, the CFTR protein is not processed and
    trafficked normally within the cell, resulting in little to no CFTR protein at the cell surface.

    ORKAMBI is a combination of lumacaftor, which is designed to increase the amount of functional protein at the cell surface by addressing the processing and trafficking defect of the protein, and ivacaftor, which is designed to enhance the function of the CFTR protein once it reaches the cell surface. ORKAMBI is an oral medicine that, if approved, would be taken as fully coformulated tablets that contain both lumacaftor and ivacaftor.

  • Yale scientists use gene editing to correct mutation in cystic fibrosis via Yale News

    SOURCE

    Yale researchers successfully corrected the most common mutation in the gene that causes cystic fibrosis, a lethal genetic disorder.

    The study was published April 27 in Nature Communications.

    Cystic fibrosis is an inherited, life-threatening disorder that damages the lungs and digestive system. It is most commonly caused by a mutation in the cystic fibrosis gene known as F508del. The disorder has no cure, and treatment typically consists of symptom management. Previous attempts to treat the disease through gene therapy have been unsuccessful.

    To correct the mutation, a multidisciplinary team of Yale researchers developed a novel approach. Led by Dr. Peter Glazer, chair of therapeutic radiology, Mark Saltzman, chair of biomedical engineering, and Dr. Marie Egan, professor of pediatrics and of cellular and molecular physiology, the collaborative team used synthetic molecules similar to DNA — called peptide nucleic acids, or PNAs — as well as donor DNA, to edit the genetic defect.

    “What the PNA does is clamp to the DNA close to the mutation, triggering DNA repair and recombination pathways in cells,” Egan explained.

    The researchers also developed a method of delivering the PNA/DNA via microscopic nanoparticles. These tiny particles, which are billionths of a meter in diameter, are specifically designed to penetrate targeted cells.

    In both human airway cells and mouse nasal cells, the researchers observed corrections in the targeted genes. “The percentage of cells in humans and in mice that we were able to edit was higher than has been previously reported in gene editing technology,” said Egan. They also observed that the therapy had minimal off target, or unintended, effects on treated cells.

    While the study findings are significant, much more research is needed to refine the genetic engineering strategy, said Egan. “This is step one in a long process. The technology could be used as a way to fix the basic genetic defect in cystic fibrosis.”

    Other Yale authors include Nicole Ali McNeer, Kavitha Anandalingam, Rachel J. Fields, Christina Caputo, Sascha Kopic, Anisha Gupta, Elias Quijano, Lee Polikoff, Yong Kong, Raman Bahal, and John P. Geibel.

    This research was supported in part by the NIGMS Medical Scientist Training Program T32GM07205 (to N.A.M.), the Hartwell Foundation (to M.E.E.) and the National Institute of Health grants R01HL082655 and R01AI112443 (to P.M.G) and R01EB000487 (to W.M.S.).

  • New antibiotic teixobactin kills drug-resistant superbugs, study says via LA Times

    SOURCE: LA TIMES

    Using soil from a grassy field in Maine and a miniaturized diffusion chamber, scientists have cultivated a microbe that could help tame the spread of antibiotic-resistant superbugs.

    When tricked into growing in a lab, the microbe makes a compound that kills strains of tuberculosis, MRSA and other deadly pathogens that are immune to even the most powerful drugs. Tests in mice showed that the newfound molecule is “exquisitely active against some very hard-to-deal-with bugs,” said Northeastern University microbiologist Kim Lewis, the senior author of a study published Wednesday in the journal Nature.

    A previously uncultured bacterium, Eleftheria terrae, is able to make teixobactin, a new antibiotic for which there is no detectable resistance. (William Fowle, Northeastern University)
    Experts said the discovery could lead to a new class of antibiotics for the first time in decades. If so, it would give doctors a much-needed weapon in the microbial arms race that has tilted in favor of bacteria.

    The World Health Organization has warned that the rise of antibiotic-resistant bacteria threatens to undermine the advances made by modern medicine. In the United States, more than 2 million people are sickened by such infections each year, and 23,000 of them die as a result.

    Most of the workhorse drugs in use today were developed at least 50 years ago. During the heyday of antibiotic research immediately after World War II, soil microbes yielded the mainstays in the fight against deadly infections.

    Lewis and his colleagues revived that idea to find a new species of bacteria they named Eleftheria terrae.

    Soil is chock full of microbes, but most don’t readily form colonies in petri dishes. In addition, many of the organisms uncovered in such samples are identical or similar to ones already developed.

    “You inevitably are rediscovering penicillin and streptomycin,” Lewis said.

    To encourage new bacteria to grow, the researchers couldn’t just dump their dirt into a laboratory dish. Instead, they isolated minuscule samples in diffusion chambers that functioned as bacterial incubators. Then they put the samples back in the soil.

    “Essentially we’re tricking the bacteria,” Lewis said. “They start growing and form colonies.”

    The experiment yielded about 10,000 strains of bacteria, which were laboriously sorted and studied.

    Researchers then checked to see whether any of the strains could kill streptococcus bacteria. Finally, they extracted the antibacterial molecule from E. terrae, one of the more promising strep killers.

    Trials on mice showed that the molecule, which they called teixobactin, rapidly cleared infections of drug-resistant strains of Mycobacterium tuberculosis and Staphylococcus aureus bacteria, according to the study. They also felled two kinds of bacteria that cause serious infections of heart tissue, Lewis said.

    The compound attacks these and other gram-positive bacteria by binding to chemicals essential to forming cell walls, causing them to break down.

    Brilacidin is the first in the new class of antibiotics being developed by Cellceutix with a wide potential application. The media has yet to catch on. A much bigger story than teixobactin as it is now has proven safety and efficacy in humans. Brilacidin and its analogs are the first new…

    “Not only one target is attacked, but multiple targets, and they are all lethal,” said study coauthor Tanja Schneider of the University of Bonn in Germany.

    This mechanism of destruction makes it much more difficult for bacteria to develop resistance to teixobactin. Most antibiotics attack proteins, but the DNA that codes for these proteins is known to mutate. Over time, some of these mutations allow bacteria to evade a drug’s lethal effects.

    The DNA that includes instructions for making cell walls is far less likely to mutate, researchers said. Indeed, when they tried to encourage bacteria to develop resistance to teixobactin, they couldn’t.

    Lewis said teixobactin kills so quickly that target bacteria will have less time in which to develop resistance.

    It took about 30 years for bacteria to develop resistance to a similarly acting antibiotic, the study noted. Researchers said any new drug probably would remain effective at least as long.

    Converting teixobactin into a safe, effective and marketable drug could take about five years and cost several hundred million dollars, according to the academic-biotech coalition that made the discovery.

    “We will probably be in clinical trials two years from now,” Lewis said.

    Lewis said the successful cultivation of the proteobacteria that produced the antibiotic suggests that mining soil for new medicines may once again prove fruitful in the search for weapons against human pathogens.

    Researchers said they would work to broaden the spectrum of bacteria the molecule can fight, and tinker with its chemistry to ensure it can be administered in reasonable doses.

    Although the study represents a “new twist” in the effort to develop new antibiotics, it remains untested in humans, said Dr. Richard Seabrook, head of business development at the London-based Wellcome Trust, which was not involved in the study. “We will not know whether teixobactin will be effective in humans until this research is taken from animal testing in the lab to clinical trials,” he said.

    NovoBiotic Pharmaceuticals of Cambridge, Mass., owns the patent for the new molecule. Several of the researchers have financial stakes in the company.

    Financial support for the research also came from the U.S. National Institutes of Health and the German government.

  • Vertex Submits Application for Combination Drug for People with 2 Copies of F508del Mutation

    SOURCE – VERTEX OFFICIAL PRESS RELEASE

     

    November 5, 2014

    Vertex Submits Applications in the U.S. and Europe for Approval of Lumacaftor in Combination with Ivacaftor for People with Cystic Fibrosis Who Have Two Copies of the F508del Mutation

    -U.S. submission includes request for Priority Review; Accelerated Assessment has been granted in the EU-

    -Approximately 8,500 people in the U.S. and 12,000 in Europe ages 12 and older have two copies of the F508del mutation-

    BOSTON–(BUSINESS WIRE)– Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) and a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for a fully co-formulated combination of lumacaftor (400mg q12h) and ivacaftor (250mg q12h) for people with cystic fibrosis (CF) ages 12 and older who have two copies of the F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. There are approximately 22,000 people with CF ages 12 and older who have two copies of the F508del mutation in North America, Europe and Australia, including approximately 8,500 in the United States and 12,000 in Europe.

    “The combination of lumacaftor and ivacaftor is the first potential treatment designed to target the underlying cause of cystic fibrosis in people with two copies of the F508del mutation, which is the most common form of the disease,” said Jeffrey Chodakewitz, M.D., Executive Vice President and Chief Medical Officer at Vertex. “Today’s submissions represent important progress toward our ongoing efforts to develop new medicines for the vast majority of people with cystic fibrosis, and we look forward to working closely with regulatory agencies to bring this treatment to eligible patients as quickly as possible.”

    In the U.S., the combination of lumacaftor and ivacaftor received Breakthrough Therapy Designation in late 2012. The U.S. submission includes a request for Priority Review, which, if granted, would shorten the FDA’s anticipated review time from approximately 12 to 8 months. The European Committee for Medicinal Products for Human Use (CHMP) has granted Vertex’s request for Accelerated Assessment of the MAA, which is given to new medicines of major public health interest and shortens the review time from approximately 210 to 150 days for the CHMP to give an opinion following the start of the review. The CHMP opinion is then reviewed by the European Commission, which generally issues a final decision within three months. If approved, Vertex would then begin the country-by-country reimbursement approval process. Both applications seek approval for a fully co-formulated combination treatment dosed as two tablets every 12 hours (four tablets daily).

    The NDA and MAA submissions are based on previously announced data from two global Phase 3 studies, TRAFFIC and TRANSPORT, and the first interim data from the subsequent rollover study in people ages 12 and older who have two copies of the F508del mutation treated with standard-of-care medicines. The TRAFFIC and TRANSPORT studies showed improvements in lung function and other measures of disease, such as pulmonary exacerbations, through 24 weeks of treatment with lumacaftor in combination with ivacaftor. Initial interim data from the rollover study showed that lung function improvements were sustained for 48 total weeks of treatment (24 weeks in TRAFFIC/TRANSPORT + 24 weeks in rollover study). The combination was generally well tolerated in all three studies. In TRAFFIC and TRANSPORT, the most common adverse events were infective pulmonary exacerbation, cough, headache and increased sputum.

    Cystic fibrosis is a rare genetic disease for which there is no cure. It is caused by a defective or missing CFTR protein resulting from mutations in the CFTR gene. The defective or missing protein results in poor flow of salt and water into and out of the cell in a number of organs, including the lungs. In people with two copies of the F508del mutation, the CFTR protein is not processed and trafficked normally within the cell, resulting in little-to-no CFTR protein at the cell surface. Lumacaftor, a CFTR corrector, is designed to address the processing and trafficking defect of the F508del-CFTR protein, increasing the amount of functional protein at the cell surface where ivacaftor, a CFTR potentiator, can further enhance its function.

    Expanded Access Programs

    In recognition of the immediate needs of some people with CF, Vertex is working to make the combination of lumacaftor and ivacaftor available to people ages 12 and older who have two copies of the F508del mutation, are in critical medical need and meet additional eligibility criteria. In the U.S., Vertex plans to begin a Phase 3b study for a limited number of people who have severe lung disease in the first quarter of 2015, followed by an expanded access program in the second quarter of the year, pending discussions with the FDA. Vertex will also work with regulatory authorities outside the United Statestoward implementing additional expanded access programs in other countries, with a goal of opening programs for eligible patients in the second quarter of 2015.

    About the Combination

    The combination of lumacaftor and ivacaftor is the first potential medicine designed to treat the underlying cause of CF in people with two copies of the F508del mutation, the most common form of the disease. In North America, Europe and Australia, there are approximately 22,000 people ages 12 and older who have two copies of the F508del mutation.

    Known as a CFTR corrector, lumacaftor aims to address the processing and trafficking defect of the F508del-CFTR protein to enable it to reach the cell surface where the CFTR potentiator, ivacaftor, can further enhance the ion channel function of the CFTR protein. Ivacaftor is designed to help the CFTR channel at the cell surface open more often to improve the transport of salt and water across the cells. In combination, lumacaftor and ivacaftor are believed to help hydrate and clear mucus from the airways.

    About Cystic Fibrosis

    Cystic fibrosis is a rare, life-threatening genetic disease affecting approximately 75,000 people in North America, Europe and Australia. Today, the median predicted age of survival for a person with CF is between 34 and 47 years, but the median age of death remains in the mid-20s.

    CF is caused by a defective or missing CFTR protein resulting from mutations in the CFTR gene. Children must inherit two defective CFTR genes — one from each parent — to have CF. There are more than 1,900 known mutations in the CFTR gene. Some of these mutations, which can be determined by a genetic, or genotyping test, lead to CF by creating non-working or too few CFTR protein at the cell surface. The defective or missing CFTR protein results in poor flow of salt and water into and out of the cell in a number of organs, including the lungs. This leads to the buildup of abnormally thick, sticky mucus that can cause chronic lung infections and progressive lung damage.

    Collaborative History with Cystic Fibrosis Foundation Therapeutics, Inc. (CFFT)

    Vertex initiated its CF research program in 1998 as part of a collaboration with CFFT, the nonprofit drug discovery and development affiliate of the Cystic Fibrosis Foundation. This collaboration was expanded to support the accelerated discovery and development of Vertex’s CFTR modulators.

    About Vertex

  • Median Age Of Survival For Canadians With CF Surpasses 50 via CF News Today

    SOURCE

    In the 1980s, life expectancy for persons with cystic fibrosis (CF) was just 12 years in the US, and around 20 in Canada. However, the median age of survival for Canadian CF patients continues on an upward trend, and is currently estimated to be 50.9 years of age — or two and a half times what it was 30 years ago, and among the highest in the world. This milestone was recently announced at the North American Cystic Fibrosis Conference in Atlanta, Georgia.

    Based on the most recent Canadian Cystic Fibrosis Registry data, which track clinical trends and insights regarding Canada’s CF population, the median age of survival reflects dedicated work of CF researchers and clinicians as it breaks the half century mark. The data are collected from all 42 CF clinics located across Canada.

    “The median age of survival in Canada for CF patients has now passed 50 years of age and shows tremendous progress in the fight against cystic fibrosis,” says Dr. Anne Stephenson, Director of the CF Registry. “We hope the Canadian Cystic Fibrosis Registry will continue to enhance knowledge and highlight key trends that will lead to improved CF research and treatments.”

    Cystic Fibrosis Canada has published an annual report on Canadian patient registry data for more than 40 years, and it has played an invaluable role in helping to improve the quality and length of life of Canadians with cystic fibrosis. The Registry is an important resource for CF clinicians to help monitor and identify emerging patterns in health outcomes of CF patients, as well as for researchers searching for a cure or control for this devastating disease.

    “This positive step forward demonstrates our enhanced focus on leading in quality improvement and excelling in CF care through our investments in research, care and advocacy,” says Ken Chan, Vice President, Advocacy, Research, and Healthcare at Cystic Fibrosis Canada. “The Registry continues to benchmark the tremendous strides we are making, and would not be possible without the funding support from our donors.”

    Cystic fibrosis is the most common fatal genetic disease affecting Canadian children and young adults — a multi-system disease that affects mainly the lungs and the digestive system. In the lungs, where the effects are most devastating, a build-up of thick mucus causes severe respiratory problems. Mucus and protein also build up in the digestive tract, making it difficult to digest and absorb nutrients from food. As improved therapies have helped to address the malnutrition issues, ultimately most deaths related to cystic fibrosis are due to lung disease. There is no cure.

    However, discovery of the gene that causes cystic fibrosis — CFTR — the first disease-causing gene to be identified and at the time of discovery, at Toronto’s Hospital For Sick Children (“SickKids”) 25 years ago last month, is touted as one of the most significant advances in the history of human genetics, and is understood to be one of the most significant breakthroughs in human genetics that has not only impacted lives of children and young adults with CF, but also paved the way for what is now known as individualized medicine.

    ChristineBear“Finding the gene opened the door to unprecedented knowledge of the disease. After its discovery we were able to study and understand how the protein made by the CFTR gene worked and what happened when it didn’t,” says Dr. Christine Bear Senior Scientist and Co-Director of the CF Centre at SickKids . “Once we figured this out, therapy that targeted defects caused by CF gene mutations could begin.”

    “We are at a new frontier of discovery for CF patients,” Dr. Bear notes in a Hospital For Sick Children release. “Over the past decade there has been tremendous progress with regards to therapy discovery conducted using generic cells induced to possess a particular CF mutant protein. These workhorse cell cultures were then used to identify the types of chemical compounds that can repair the defect caused by that specific mutation. However, there were limitations since these cells did not exactly mimic the cell in the lungs, liver or pancreas of CF patients. While this approach led to the discovery of one drug called KALYDECO, we believe that a new discovery strategy is needed during the upcoming 10 years to find the next generation of therapies effective in treating all CF patients.”

    KALYDECO, the drug referred to by Dr. Bear, is exclusively indicated to treat only a relatively small sub-minority of what is an already relatively small number of cystic fibrosis cases overall who have at least one copy of the G551D mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The CF prevalence rate in general in the most vulnerable ethnic group, Caucasians, is just one in every 2,500 births. Consequently, since the proportion of cystic fibrosis cases positive for the G551D mutation in the CFTR gene is very low, and only few CF patients eligible to use KALYDECO, economies of scale associated with sales of more widely-prescribed drugs don’t obtain with KALYDECO, keeping the cost per patient high.

    The release notes that the CF story at SickKids has always been one of collaboration. The gene discovery was a partnership between SickKids and the University of Michigan; the creation of the CF mutation database is an international collaboration; and the most recently, the pharmaceutical and philanthropic communities and SickKids came together to develop KALYDECO.

    Cystic Fibrosis Canada provides nearly $2 million in funding each year to CF clinics through the Clinic Incentive Grants program to support efforts in providing data to the Registry.

  • UNC Researchers Find New CF Drugs Counteract One Another’s Effectiveness via CF News Today

    SOURCE

    Findings of new study led by Martina Gentzsch, PhD, at the University of North Carolina School of Medicine and the UNC Marsico Lung Institute in Chapel Hill, N.C. could help drug developers improve compounds designed to correct CFTR proteins in cystic fibrosis (CF) patients. In lab experiments using tissue samples cultured from cystic fibrosis patients, UNC Dr. Gentzsch and her team of scientists have demonstrated that a new CF drug counteracts the intended beneficial molecular effect of another CF drug.

    The finding, published in the journal Science Translational Medicine, shows how a mutant CFTR protein becomes unstable and loses its ability to function properly when in the presence of the two drugs. The research offers several insights into how novel CF pharmacotherapies could be improved.

    The Science Translational Medicine study, entitled “Potentiator ivacaftor abrogates pharmacological correction of F508 CFTR in cystic fibrosis,” (Sci Transl Med 23 July 2014: Vol. 6, Issue 246, p. 246ra96 DOI: 10.1126/scitranslmed.3008680) is coauthored by Dr. Martina Gentzsch; Research Assistants Deborah M.

  • Vertex’s Two-Drug Cystic Fibrosis Treatment Shows Promise in Clinical Trials via NY Times

    Vertex Pharmaceuticals said on Tuesday that a combination of two of its drugs had successfully treated cystic fibrosis in closely watched clinical trials, potentially clearing the way for approval of a new option for nearly half the patients with the genetic disease.

    The drug combination, when compared with a placebo, improved the lung function of patients and also reduced pulmonary flare-ups, which can lead to hospitalization.

    “These data, the totality and the consistency, were as much or more than we were hoping for,” Dr. Jeffrey Leiden, the chief executive of Vertex, said in an interview. He said the company would submit applications for approval of the combination in the United States and Europe in the fourth quarter.

    Still, the improvement in lung function of between 2.6 and 4 percentage points after six months, compared with the lung function of patients who took the placebo, was at the low end of what some doctors would consider meaningful and what some investors were anticipating.

    “Would I have rather seen 6, 7 percent? Of course I would have,” said Dr. Bonnie W. Ramsey, a professor of pediatrics at the University of Washington and one of the lead investigators for the studies.

    Dr. Ramsey, who was briefed on the results of the test, which were analyzed by Vertex, said that an improvement of 3 percent would be imperceptible to patients. But she said that if the effect lasted longer than six months, it could make a meaningful difference over the long run.

    About 30,000 Americans and about 75,000 people globally have cystic fibrosis, an inherited disease caused by mutations in a gene that controls the transport of water and salt into and out of cells. The disease causes mucus to build up in the lungs, which leads to infections and lung damage. Many people with the disease die before reaching 40.

    Vertex won approval for one cystic fibrosis drug, Kalydeco, in 2012. But Kalydeco, also known as ivacaftor, works for a mutation found in only about 4 percent of patients.

    The combination, consisting of ivacaftor and an experimental drug called lumacaftor, would be applicable to nearly half of cystic fibrosis patients: those with two copies of the most common mutation, known as F508del.

    Although there are other drugs available, such as antibiotics and an enzyme to loosen mucus, Kalydeco was the first drug to correct the underlying genetic defect, and lumacaftor could be the second. The gene responsible for the disease was discovered in 1989 by, among others, Dr. Francis S. Collins, now the director of the National Institutes of Health.

    The results of Vertex’s trials were being closely watched on Wall Street as a so-called binary event, one that could cause the company’s shares to rise or fall sharply and that could also perhaps influence investor sentiment about the entire biotechnology industry.

    “It’s not an exaggeration to say that billions of dollars in value, for Vertex and the overall biotech sector, hinge on” the results, Geoffrey C. Porges, an analyst at Sanford C. Bernstein & Company, wrote in a note last week.

    That is because the future of Vertex, which is based in Boston, depends on its being the leader in treating cystic fibrosis. Incivek, its drug for hepatitis C, was approved only three years ago and was a big seller but has already faded in the face of competition from Gilead Science’s Sovaldi.

    Although the number of patients with cystic fibrosis is small, analysts say Vertex could reap billions of dollars in annual sales because drugs for rare diseases are expensive. Kalydeco costs more than $300,000 a year and had sales last year of $371 million.

    Some doctors have protested the price, including authors of a commentary published in the Journal of the American Medical Association in October.

    Dr. Leiden said it was “way too early” to talk about the price of lumacaftor, which previously was called VX-809.

    The nonprofit Cystic Fibrosis Foundation financially supported the development of both Kalydeco and lumacaftor and is entitled to royalties on sales of both drugs.

    The two trials involved a total of about 1,100 patients, age 12 and over, in North America, Europe and Australia. Each trial had three arms. Patients in two of the arms took ivacaftor plus either a low or high dose of lumacaftor. Patients in the third arm received a placebo.

    Lung function was assessed by the maximum a person could exhale in one second, a standard test. At the start of the trial, the patients had average lung function, based on this measure, that was 61 percent of what would be predicted for people their age.

    After 24 weeks, lung function had improved in all four groups that got the drug combination, by between 2.2 and 3.6 percentage points, meaning their average lung function was somewhere around 64 percent of what would be normal for their age. The lung function of those who got the placebo fell slightly.

    Dr. Leiden emphasized that pulmonary exacerbations, or flare-ups, had been reduced about 30 percent to 40 percent. He also noted that the drug had helped patients, who also tend to have digestive problems, to gain weight.

    “Every day you don’t spend in the hospital and every pound you gain is meaningful to that patient and their family,” he said.

    About 4.2 percent of those getting the drugs dropped out of the trial because of side effects like liver problems, compared with only 1.6 percent of those receiving the placebo. Shortness of breath was another side effect. But more than 1,000 patients elected to continue on the drug combination after the trial ended.

    The results were announced in a news release by the company and have not been peer reviewed by outside experts.

  • Aptalis Pharma Studies Panzytrat in Cystic Fibrosis Patients in Phase 4 Trial via CF News Today

    via Cystic Fibrosis News Today

    Aptalis Pharma continued to evaluate its pancreatic enzyme products (PEPs) in patients with cystic fibrosis and exocrine pancreatic insufficiency in its Phase 4 clinical trial of Panzytrat® 25,000. Results show that patients taking Panzytrat had better control over their steatorrhea, or fecal fat content.

    The study was designed to evaluate cystic fibrosis patients with exocrine pancreatic insufficiency while taking Aptalis’ Panzytrat 25,000 or Abbott’s Kreon® 25,000. Notably, Kreon (also Creon) was one of the first PEPs approved by the FDA, and in 2009, Solvay Pharmaceuticals (now Abbott) established the efficacy and safety of Creon 24,000 in cystic fibrosis patients with exocrine pancreatic insufficiency.

    Two treatment periods were involved: a 14-day treatment with either Panzytrat or Kreon and a 14-day treatment with the opposite intervention (Kreon or Panzytrat). In total, 81 of the original 87 enrolled patients completed the trial, and withdrawals were due to adverse events.

    Analysis of the primary outcome measure, coefficient of fat absorption, showed no difference between treating patients with Panzytrat or Kreon. Coefficients were 78.27% and 80.35%, respectively (p=0.4590). Secondary measures, which included daily number of stools, percentage of normal stools, and frequency of abdominal symptoms, showed similar results between treatments. Although no statistical analyses were conducted to confirm a difference, more patients treated with Panzytrat experienced adverse effects (32 versus 20 treated with Kreon).

    Panzytrat 25,000 capsules are porcine-derived preparations of pancrelipase and contain lipase, protease, and protease. Cystic fibrosis patients with exocrine pancreatic insufficiency are benefited by PEPs such as Panzytrat because patients are deficient in the enzymes required for digestion of fats, carbohydrates, and proteins. Panzytrat 25,000 is specially formulated to avoid inactivation by stomach acids and intestinal pH. It is only indicated for use in patients 18 months and older.
