About Simeprevir

Simeprevir is an investigational NS3/4A protease inhibitor jointly developed by Janssen R&D Ireland and Medivir AB, for the treatment of genotype 1 and genotype 4 chronic hepatitis C in adult patients with compensated liver disease, including all stages of liver fibrosis. Simeprevir works by blocking the protease enzyme that enables the hepatitis C virus to replicate in host cells.

Janssen is responsible for the global clinical development of simeprevir and has acquired exclusive, worldwide marketing rights, except for in the Nordic countries. Medivir will retain marketing rights for simeprevir in these countries.

Simeprevir was approved in Japan in September 2013 for the treatment of genotype 1 hepatitis C. In the U.S., the New Drug Application (NDA) filed by Janssen for simeprevir administered once daily in combination with pegylated interferon and ribavirin for the treatment of genotype 1 chronic hepatitis C in adult patients was granted Priority Review designation by the Food and Drug Administration (FDA) in May. A Marketing Authorisation Application was submitted to the European Medicines Agency (EMA) in April seeking approval of simeprevir for the treatment of genotype 1 or genotype 4 chronic hepatitis C.

To date, more than 3,700 patients have been treated with simeprevir in clinical trials. Simeprevir is also being studied in several interferon-free regimens using selected combinations of direct-acting antiviral agents with different mechanisms of action.

For additional information about simeprevir clinical trials, please visit www.clinicaltrials.gov.

About Sofosbuvir

Sofosbuvir (formerly referred to as GS-7977) is a once-daily nucleotide analog polymerase inhibitor for the treatment of HCV infection being developed by Gilead Sciences, Inc. Sofosbuvir is being evaluated as part of multiple therapeutic regimens, including programs with RBV alone and in combination with peg-IFN and RBV.

Hepatitis C Newsletters, New Drugs, and A New Book On Treatment

 Newsletters, New Drugs, and A New Book On Treatment

Hello Folks,
Here we are a week into October, a month for picking apples, carving pumpkins, and preparing for the review of two promising HCV drugs, sofosbuvir and simeprevir by the Antiviral Drugs Advisory Committee.

If all goes well during the approval process, these drugs could be approved by early December of this year.

Physicians predict with new agents so close to FDA approval people who have waited to begin HCV therapy are now preparing for treatment.

The decision to begin therapy is a difficult one, understanding the regimens, liver disease and time frames on the availability of new drugs can be overwhelming.

Unfortunately not everyone can wait for new therapies to be approved, nor should they. If you are preparing for treatment a new book is available to guide you gently through the process.

As mentioned yesterday on the blog, Lucinda K. Porter, RN, the author of Free from Hepatitis C has just published "Hepatitis C Treatment One Step at a Time" - a must read for anyone considering therapy.
The HCV community is very familiar and grateful for her contributions to HCV Advocate, we all read both "Snapshots" and "HEALTHWISE" which are published each month in their popular newsletter.
Lucinda is an active speaker, educator, and patient who has previously undergone HCV therapy twice, she is currently awaiting results from her third attempt. We all wait with her, knowing in our heart this time she will be successful!

Medivir AB has reported that Janssen Pharmaceutical R&D Ireland (Janssen) has been informed by the Japanese Ministry of Health, Labour and Welfare (MHLW) that simeprevir has been approved for the treatment of genotype 1 chronic  hepatitis C virus (HCV) infection.

Sofosbuvir and Daclatasvir - Drug therapy offers new hope to liver transplant hepatitis C patients
Dr. Robert Fontana, professor of internal medicine and  medical director of  liver transplantation at U-M Health System, obtained  emergency approval from the federal Food and Drug Administration to give Gholston a treatment that combined two oral antiviral medications,
sofosbuvir and daclatasvir.

Achillion Pipeline Update: Hepatitis C Drug Still on Hold by U.S. FDA
Achillion today received a response from the U. S. Food and Drug Administration, or FDA, on the clinical hold related to sovaprevir, Achillion's NS3 protease inhibitor. The FDA response indicated that, while Achillion's submission addressed all issues noted in the FDA's June 29, 2013 letter, the FDA concluded that the removal of the clinical hold is not warranted.

Real-world SVR rate about 33% with hepatitis C triple therapy
Only one-third of a group of patients with hepatitis C achieved a sustained virologic response (SVR) when a protease inhibitor was added to standard ribavirin and interferon dual therapy

Of 42 patients who started on triple therapy with boceprevir, 9 had to drop out because of previously recognized adverse events, including thrombocytopenia, neutropenia, anemia, and depression. Five other patients did not comply with treatment, and treatment failed in 10. About half of the patients were new to therapy and the rest either non- responders to dual-therapy or triple-therapy relapsers.

Of the 18 who completed treatment, 9 achieved SVR at 3 months and 5 at 6 months. The four remaining patients relapsed.

All-Oral Therapy With Sofosbuvir and GS-0938 for 14 Days in Treatment-Naive Geno 1 
Treatment with the HCV nucleoside inhibitors sofosbuvir and GS-0938—alone and in combination—led to rapid and substantial reductions in viral load without any incidences of viral breakthrough. Sofosbuvir demonstrated potent HCV RNA suppression when administered alone for 7 days, an antiviral effect almost double that observed with GS-9851 at the same dose. Sofosbuvir is currently in phase 3 clinical development as a possible backbone of multiple anti-HCV regimens for chronic hepatitis C.

Combining Drugs Cures Some With Hepatitis C
This isn't new information, but the video was released a few weeks ago. It discusses a study published in the Journal of the American Medical Association using Sofosbuvir/Ribavirin without interferon in genotype 1 patients who have characteristics associated with poor response to other treatments.

Syndromes and conditions linked to hepatitis C
This review aims to provide an overview of the conditions with the greatest level of evidence supporting a direct link with HCV, as well as looking at the potentially most life-threatening manifestations, with a focus on investigations and management.

Hepatitis C Treatment: When You Can't or Don't Want to Wait
The current treatment for hepatitis C consists of taking peginterferon and ribavirin. If you have genotype 1, then you take a third drug that is a protease inhibitor (either Incivek or Victrelis). The side effects of the current treatment are quite challenging, so much so that many hepatitis C patients are postponing treatment, opting to wait for interferon-free regimens. 

Some patients can't wait........

Awareness
 Canada should begin screening 'Baby Boomers' for the hepatitis C virus infection, since this age group is likely the largest group to have the illness, and most don't know they have it, say a group of liver specialists in the Toronto Western Hospital Francis Family Liver Clinic.

 Cirrhosis and Fibrosis
CAP offers a series of short lectures on hepatitis C, in this 20 minute video: Cirrhosis: a scarring of the liver,  Dr. Robert Gish explains the scaring process in detail
The present study establishes the benefits of the low-calorie diet and low-fat diet in management of patients with hepatitis C regarding improvement of insulin resistance, steatosis and also liver fibrosis.

Overweight or obese patients with hepatitis C undergoing a lifestyle intervention (specific dietary intervention and physical activity) for 1-year  had significant improvements in body weight, lipid and hepatic profiles.

Dr. Joe Galati - Watch: Hepatitis C Diet and Exercise
It is now well known that obese individuals with hepatitis C have a higher chance of developing fibrosis, scarring, and cirrhosis of the liver. Diabetes, a fatty liver, and elevated levels of insulin also contribute to a greater chance of scarring and cirrhosis.

Alcohol and The Liver
Watch: Alcohol, Acetaminophen, Liver, Cirrhosis and Transplant
In Houston, Dr. Joe Galati, Medical Director-Center for Liver Disease and Transplantation, and Dr. Howard Monsour, Chief-Hepatology at Houston Methodist discuss the effects of alcohol on the liver.

The Flu
Chronic hepatitis C can increase your risk of complications from the flu, but how effective is the flu vaccine during HCV therapy and should people on treatment be vaccinated?

Flu Forecast
A new tool that can predict when the flu will reach your area.
Just enter your zip code and view your flu risk for the next three weeks.

Example:
SAN FRANCISCO -- Flu vaccination sharply reduced the risk of community-acquired pneumonia, one of the most serious complications of influenza, a researcher said here.

In a case test-negative study, flu vaccination was associated with a 59% reduction in the risk of being admitted to hospital with pneumonia, according to Carlos Grijalva, MD, of Vanderbilt University in Nashville, Tenn.

However, vaccine efficacy appeared to be higher in children than in adults, Grijalva reported at the IDWeek meeting.

High-Dose Flu Vax Better for Frail Elderly
Among the frail elderly in long-term care, a high-dose influenza vaccine improved antibody responses compared with standard vaccines, a researcher said. The high-dose vaccine was approved in 2009 for people 65 and older, Zimmerman noted, but it was tested in healthy people, with an average age of 73, living in the community

October is National Liver Awareness Month

 More than 75 percent of the estimated 3 million US citizens with HCV are baby boomers. The Centers for Disease Control recommends that all baby boomers be tested for hepatitis C one time with a simple blood test. The CDC warns that baby boomers do not know enough about the health care they received in the 1970s and 1980s—including whether they received transfusions or were exposed to blood in other ways putting them at risk for contracting HCV. 

As long as we are healthy, there is much about our own bodies that we simply take for granted. The liver, for example, is one organ that is not always well understood by most people. The liver is the largest organ inside the human body. It filters harmful substances from the blood, makes substances that digest food, and changes food into energy. Its healthy functioning is vital to our overall health.

October is National Liver Awareness Month, an opportunity for all of us to learn a little more about the liver's essential role. During this month, health providers, hospitals and organizations like the American Liver Foundation are urging Americans across the nation to take control of their health by learning about this important organ - how it functions, how to spot the common signs of liver disease, and what steps people can take to protect their liver. Education is especially important in the fight against liver disease - which is rapidly becoming one of the nation's most serious public health problems.

Liver disease ranks as a top 10 cause of death for Americans, with more than 26,000 people dying each year from some form of chronic liver disease. More than 30 million Americans - one in every 10 U.S. citizens - are affected by some kind of liver disease, including hepatitis, cirrhosis and liver cancer. In fact, unlike most cancers, the incidence of liver cancer is actually increasing.

Getting plenty of the right kind of exercise and eating good foods are both very important to maintaining a healthy liver. Here are a few other things you can do to maintain good liver health:

• Consume alcohol only in moderation.

• Discuss your current mix of medications with your physician. Taking too many medicines can be toxic to your liver.

• Avoid mixing alcohol with other drugs or medications unless approved by a physician.

• Ensure proper ventilation when using aerosol cleaning sprays.

• Take precautions when working with chemicals. Pesticides, herbicides and other chemicals can cause liver damage when they come into contact with the skin.

Many forms of liver disease are preventable through healthy lifestyle choices like exercise and eating the right foods. Alcohol-related liver disease, for example, is caused by excessive alcohol consumption and is the most common preventable type of liver disease. Other types of liver disease, particularly hepatitis A and B, can be controlled by vaccines. If undiagnosed and left untreated, however, Hepatitis B can lead to serious illness such as cirrhosis and liver cancer.

The liver processes everything we eat, drink, breathe and even put on our skin. When the liver is not functioning properly, it can result in acute and chronic illnesses, or even death. Unfortunately, many people do not recognize the symptoms of liver disease and are unaware they have an illness until it's too late.

Some signs that may indicate liver disease include:

• Unusually dark urine, unusually light-colored stools, bloody stools or stools that are tar-like.

• A yellowish discoloration of the skin or eyes.

• Abdominal swelling or severe abdominal pain.

• Chronic fatigue, nausea or loss of appetite.

People exhibiting one or more of these symptoms should contact their physician. However, people with liver disease often experience no symptoms, so it is important that patients get regular screenings, know their risk factors and talk to their healthcare provider about whether they may be at risk for hepatitis or liver disease


Off The Cuff
Elderly Vegas man sentenced to 17 years in fake stem cell case
 An 87-year-old Las Vegas man was sentenced to serve more than 17 years in federal prison in a case involving the implantation of phony stem cells in chronically ill patients.

As described by an indictment and evidence in Sapse's trial, the Las Vegas resident hired a pediatrician, Ralph Conti, in 2005 as part of a scheme in which Sapse convinced patients to undergo an experimental implant procedure, promising to cure them of their ailments. Conti served to perform the procedure on at least 34 patients throughout 2006, knowing they would not benefit them in any way, Bogden's office said.

Lucinda K. Porter, RN: Hepatitis C Treatment One Step at a Time

Hepatitis C Treatment One Step at a Time

From the mid-1990s Lucinda K. Porter, RN, has devoted consistent and generous time as a hepatitis C advocate, educator, and author. Ms. Porter has written for numerous publications including a monthly health column for HCV Advocate.

The author's work has provided a global audience with facts, information, and skills needed to actively navigate conflicting and at times confusing research about the virus. This acquired knowledge has helped countless people eventually come to terms with their disease and explore all possible treatment options.

Ms. Lucinda K. Porter the author of "Free from Hepatitis C" has graced the HCV community with a second book "Hepatitis C Treatment One Step at a Time".

The timing of the book couldn't be more perfect. With screening strategies in place by the CDC and Task Force which recommend all people born from 1945 through 1965 get tested one time for hepatitis C, and new drugs moving through the final stages of FDA approval - the need for a guide during HCV therapy is paramount.

This comprehensive book provides tips for people starting hepatitis C treatment while slowly dissipating the fear of the unknown.

Some commonly asked questions are addressed such as; Will I be able to work during treatment? What about the side effects? How will these drugs make me feel? When will I know treatment is working?

Coping with the challenges of therapy may seem impossible at first, but getting to the finish line is made easier with each turn of the page. The author takes us on a physical and emotional journey of spiritual strength.

Porter offers what our families or physicians can not, advice on treatment from a patients perspective. She has undergone therapy twice before, and is currently awaiting the outcome from a third attempt.

The former Stanford nurse understands what is needed to succeed and thrive during the sometimes grueling days of treatment. The reader is gently cradled through therapy with daily advice, inspirational quotes, and encouragement. With each day of treatment a new bit of information awaits, starting with the first day which continues through 48 weeks.

The HCV community is fortunate to have such a compassionate expert offering us a personal guide through treatment. Ms. Porter's calm voice can be felt strongly throughout the book, a presence that will surely be reassuring to the reader.

Hepatitis C Treatment One Step at a Time is now available for your consideration, an excerpt is offered on the author's website.

Telaprevir-induced retinopathy:Adverse effect during hepatitis C triple antiviral therapy

J Gastroenterol. 2013 Oct 1. [Epub ahead of print]

Telaprevir-induced, but not pegylated interferon-associated, retinopathy as a noteworthy adverse effect during triple antiviral therapy in patients with chronic hepatitis C.

Department of Gastroenterology and Hepatology, Faculty of Medicine, Saitama Medical University, 38 Morohongo, Moroyama-Machi, Iruma-Gun, Saitama, 350-0495, Japan.

Abstract
BACKGROUND:
The significance of retinopathy during triple therapy with telaprevir is uncertain.

METHODS:
Ophthalmologic examination was done prospectively before and every month during the therapy in 95 CHC patients.

RESULTS:
Retinopathy was found in 46 (48.4 %), and the specialists recommended discontinuation of the therapy in 9 (9.5 %). Such lesions may develop as adverse effects by telaprevir, since the lesions disappeared following discontinuation of telaprevir in a 65-year-old man, in whom both pegylated-interferon (Peg-IFN) and ribavirin were continued, and reappeared when he took telaprevir again by his decision. Multivariate analysis revealed that interleukin 28B single-nucleotide polymorphism (IL28B SNP) and anemia development during the therapy were independent factors associating retinopathy.

CONCLUSION:
Ophthalmologic examinations should be done carefully during triple therapy, since the incidence was higher than that in previous Peg-IFN therapy, and lesions may develop as adverse effects by telaprevir, but not by Peg-IFN, especially in those showing preferable IL28B SNPs allele and/or anemia during the therapy.

Emerging resistance using sequential direct-acting antiviral agents for Hepatitis C

Emerging resistance using sequential direct-acting antiviral agents for Hepatitis C

A translational study published in the latest issue of the American Journal of Gastroenterology investigates resistance emergence using sequential direct-acting antiviral agents for Hepatitis C using ultra-deep sequencing.

Direct-acting antiviral agents against hepatitis C virus (HCV) have recently been developed and are ultimately hoped to replace interferon-based therapy.

However, direct-acting antiviral agents monotherapy results in rapid emergence of resistant strains and direct-acting antiviral agents must be used in combinations that present a high genetic barrier to resistance, although viral kinetics of multidrug-resistant strains remain poorly characterized.

Dr Kazuaki Chayama and colleagues from Japan studied the emergence and fitness of resistance using combinations of telaprevir and NS5A or NS5B inhibitors with genotype 1b clones.

HCV-infected chimeric mice were treated with direct-acting antiviral agents, and resistance was monitored using direct and ultra-deep sequencing.

Combination therapy with telaprevir and BMS-788329 (NS5A inhibitor) reduced serum HCV RNA to undetectable levels.

The team noted that presence of an NS3-V36A telaprevir resistance mutation resulted in poor response to telaprevir monotherapy but showed significant HCV reduction when telaprevir was combined with BMS-788329.

However, a BMS-788329-resistant strain emerged at low frequency.

The team noted that infection with a BMS-788329-resistant NS5A-L31V mutation rapidly resulted in gain of an additional NS5A-Y93A mutation that conferred telaprevir resistance during combination therapy.

The research team found that infection with dual NS5AL31V/NS5AY93H mutations resulted in poor response to combination therapy and development of telaprevir resistance.

Although HCV RNA became undetectable soon after the beginning of combination therapy with BMS-788329 and BMS-821095 (NS5B inhibitor), rebound with emergence of resistance against all 3 drugs occurred.

Triple resistance also occurred following infection with the NS3V36A/NS5AL31V/NS5AY93H triple mutation.

Dr Chayama's team concludes, "Resistant strains easily develop from cloned virus strains."

"Sequential use of direct-acting antiviral agents should be avoided to prevent emergence of multidrug-resistant strains."

FDA Panel Review On For Gilead's Sofosbuvir Despite Government Shutdown


Despite FDA shutdown, Gilead, Amarin still on for high-profile panels

October 1, 2013 | By Damian Garde

As of today, the FDA has been virtually halved, and while the mandatory furloughs spelled out by a government shutdown may imperil some of the agency's duties, it appears that drug approvals and reviews will go unmarred.

Yesterday, an FDA spokesperson told FierceBiotech that, because agency advisory panels are funded by industry-paid user fees and not tax appropriations, "generally speaking, these meetings would continue in some way" after a shutdown. That's not exactly a clear-cut guarantee, and, unsurprisingly, there's no one around to clarify this morning. That said, the drugmakers with products on the line are optimistic their timelines will stay intact.

Gilead ($GILD) has an Oct. 25 date to with the Antiviral Drugs Advisory Committee to discuss sofosbuvir, a hep C treatment it hopes to get approved this year, and that meeting hasn't been canceled, the company told us. Johnson & Johnson ($JNJ) is due before the same panel the day before to discuss simeprevir, its late-stage hepatitis C treatment under the FDA's priority review, but the company couldn't confirm whether the review was on schedule.

Amarin Pharmaceuticals ($AMRN) is gearing up for a weighty Oct. 16 panel vote on whether to approve Vascepa paired with statins to reduce cholesterol, and the company said it hasn't been informed of any delays. On the device side, Medtronic ($MDT) has an Oct. 8 date with the Circulatory System Devices Panel, asking for an expanded indication for its fleet of pacemakers and implanted defibrillators, and the company said that meeting is still on.

The FDA is down 6,620 employees this morning, losing about 45% of its staff to furloughs, and the agency has suspended the "majority" of its internal lab research, according to a Department of Health and Human Services briefing. Also on hold is the FDA's usual stream of guidances and new regulations, as government agencies have been instructed to publish only documents that support activities related to "imminent threats to the safety of human life or protection of property."

It remains anyone's guess how long the shutdown will last. The House and Senate have thus far traded party-line votes on sure-to-be-rejected budget bills, with Republicans pushing to include provisions that would delay aspects of the Affordable Care Act while Democrats insist on a stripped-down resolution to reopen the government.

Shutdown dims lights at FDA, NIH and CDC



The government shutdown that went into effect at midnight put 800,000 government employees out of work for the duration. The fallout includes 40,513 Health and Human Services employees, or 52% of the department's staff, while 48% will continue to come in and be paid.

At the FDA, this means 45% of the agency's staff has been sent home. Assistant commissioner of media affairs Steven Immergut emailed MM&M that of the 55% of staff who are allowed to work, 74% of them are funded by user fees. The shutdown means the FDA will not be able to perform tasks including routine inspections, some compliance activities, and “the majority of the laboratory research necessary to inform public health decision-making.”

Of the media affairs staff, Immergut was the only one of three media affairs specialists allowed to show. Colleagues Heidi Rebello and Erica Jefferson's out-of-office messages noted, “I am out of the office on furlough and cannot respond to your email.”

The Street's Adam Feuerstein noted last week that the shutdown could mean Amarin (vascepta), Johnson & Johnson (simeprevir) and Gilead (sofosbuvir) see their advisory review committee days evaporate.

Also as part of the shutdown, the National Institutes of Health will not review grant applications or begin new treatment protocols, and will cease other functions. The Centers for Disease Control and Prevention is also scaling back, and will not be able to provide state and local support for infectious disease surveillance or the annual seasonal influenza programs, in addition to stopping other activities.

Although the FDA's homepage did not note the shutdown, making it appear like a normal day, the NIH's website features a big red box noting, “due to the lapse in government funding, the information on this web site may not be up to date, transactions submitted via the web site may not be processed,” and forwarding users to USA.gov. This second site's featured news included a note that the government had shut down and provided an 800 number to call for questions, which was followed by a second story on auto-rotate encouraging readers to sign up for health exchanges. These exchanges, part of healthcare legislation that put the government in deep freeze, began accepting members today. Money had already been allocated to the exchanges, insulating them from the standoff.

Shutdown forces new NIH clinical trial patients to wait


Participants who are already in studies are still being treated and will continue with their trials.

Shutdown forces new NIH clinical trial patients to wait

(CNN) -- Every week, hundreds of new patients, including children with cancer, are admitted to new clinical trials through the National Institutes of Health.

But because of the government shutdown, those patients who are newly registered are being put on hold until the government resumes operation.

About 200 people register for NIH clinical trials every week. But those patients are being told they will have to wait until the government starts up again to begin their trials, according to NIH spokesman, John Burklow.

"In fact six new studies would have started this week that we are deferring," Burklow said.

Of that 200, approximately 30 are children, and about 10 of those children are cancer patients, Burklow said.

Burklow did note that participants who are already in studies are still being treated and will continue with their trials. Burklow also said patients in desperate need of treatment will be handled differently and will more than likely be seen by physicians or nurses at the NIH Clinical Center.

About 75% of NIH's employees -- or about 14,700 people -- have been furloughed.
