Hepatitis C: The Post Interferon World has Five Scoops of Good News

Hep C:  The Post Interferon World is Five Scoops of Good News

  1.  Increased number of patients screened and identified
  2.  Increased options for those who failed previous therapies
  3.  Improved patient compliance
  4.  Possibilities of patient-guided treatment
  5.  Decreased need for liver transplantation

  •   I quit writing my blog when I saw the first ad for Hepatitis C treatment on television. The representative people were not parrot heads or crack heads. They were typical ad people like Crestor or Nexium. These ads will bring people in for testing and treatment.  The early treatment decreases transplantation demands. But there is still a lot of Hepatitis C news, so I am back.

A friend of mine started round four of treatment three days ago and she is scared.  Because of Interferon and depression, she could not complete previous treatments. No pledge from me or her physician made a dent in her fear but time will show her. Her new protocol doesn’t call for Interferon, and she is on preventive anti-depression medication. The three drug cocktail for her is one of many not available six months ago, a bygone era.

I recall Fridays during treatment, Interferon injection days. Bathing and grooming started on Wednesdays. I could schedule most work meetings (via telephone) for Thursday and Friday. There is much compliance built around Interferon day. For me, there came the day I could not  work and Friday no longer mattered. Unfortunately leaving work isn’t always an available solution. I lost my career when I returned and I was still sick from drugs. Luckily I retired with benefits.  When I went through treatment # 2, I wasn’t working and could get all the rest required. In the post Interferon world of (mostly) no Interferon and ribavirin this may not be an issue, thus better patient compliance, and cure.

 

And now about patient-guided therapy and no you do not get to select from a menu. For those of you following genotyping using IL2b.  Researchers predict (I love that phrase) which treatments will work best in your body.  That will partially determine the treatment drugs for you, thus ruling out waste-of-time and money treatments.

The Depression Road Goes On Forever and The Party Never Ends *

Hepatitis C and Depression: I should be weary of this subject, but I’m only weary of depression. Thirteen months ago I completed a clinical trial for Hepatitis C. I was cured, c-u-r-e-d.

 GS-US-256-0124-A Phase 2B, Trial Evaluating Using Combinations of Oral Antivirals (GS-5885, GS-9451), PegInterferon Α and Ribavirin In Treatment Experienced Subjects  With Chronic Genotype 1 Hepatitis C Virus Infection

Last month I went in for my one-year follow-up visit where it was confirmed “No Virus After One Year!”.  Okay, maybe it’s true.  Maybe. I answered questions about my mental well-being.  I felt great and said so.  Later I remembered that I felt great because I was on two anti-depressant drugs, Lexapro (escitalopram)  and Wellbutrin (bupropion XL) with a splash of trazodone at bedtime.

BTW, I think everyone should speak about their antidepressants. I know there’s a bunch of us out there.  Just look at the sales $$$.     I worked for Lilly when they launched Prozac.  Rather than get it for free, I paid at the retail pharmacy because I didn’t want anyone to know.  That’s Bull Corn.  Bull Corn?  Where did that come from?

Where was I?  So two weeks ago, my psychiatrist,  (who treats Hep C patients) began to decrease the Lexapro with the goal of decreasing my antidepressant load.  My scaffolding crumbled under me and I spiraled into an anxiety-ridden, weeping insomniac in just a few days and nights.

I've come undone
I’ve come undone

.So,  I am miserable and looking at increasing drugs.  My first thought was that I am FUBAR (Fucked Up Beyond All Reason/Recognition/Repair  military slang) and that’s that.  My second thought was to work closely with Dr _ who assures me that this is a minor setback. Minor to someone else maybe. How quickly I become self-absorbed.

Now, after 400 words, the reason for this blog.  Today I received this article from  Medscape.

 Psychiatric Treatment Considerations With Direct Acting Antivirals in Hepatitis C   Sanjeev Sockalingam, Alice Tseng, Pierre Giguere, David Wong
BMC Gastroenterol. 2013;13(86)

(Newly published articles in my areas of interest for August 9, 2013: Medscape)

Can’t resist the title can you?  I know I can’t.

Being a Doctor of Pharmacy and a scientist, I love articles like this. It takes my entire nineteen years of schooling to follow the data dump. Gastroenterologists and Psychiatrists won’t read this article. It falls into a discrete category that gets filtered out during literature searches. DAAs means previrs ( boceprevir / telaprevir).

Abstract

Background Despite recent advances in hepatitis C (HCV) treatment, specifically the addition of direct acting antivirals (DAAs), pegylated interferon-alpha remains the backbone of HCV therapy. Therefore, the impact of DAAs on the management of co-morbid psychiatric illness and neuropsychiatric sequelae remains an ongoing concern during HCV therapy. This paper provides a review of the neuropsychiatric adverse effects of DAAs and drug-drug interactions (DDIs) between DAAs and psychiatric medications.

Methods We conducted a PubMed search using relevant search terms and hand searched reference lists of related review articles. In addition, we searched abstracts for major hepatology conferences and contacted respective pharmaceutical companies for additional studies.

Results Limited data is available on the neuropsychiatric adverse effects of DAAs; however, data from major clinical trials suggest that DAAs have minimal neuropsychiatric risk. DAAs can potentially interact with a variety of psychotropic agents via cytochrome P450 and p-glycoprotein interactions. Triazolam, oral midazolam, St. John’s Wort, carbamazepine and pimozide, are contraindicated with DAAs. DDIs between DAAs and antidepressants, anxiolytics, hypnotics, mood stabilizers, antipsychotics and treatments for opioid dependence are summarized.

Conclusions Although DAAs do not add significant neuropsychiatric risk, the potential for DDIs is high. Consideration of DDIs is paramount to improving medication adherence and mitigating adverse effects during HCV therapy.

So the abstract  (I saved you from the entire article)  kinda says: We don’t know enough to draw any conclusions so we caution you when using any drugs metabolized by the liver, including antidepressants. Terms: pharmacokinetics (where the drug goes in your body and how your body changes it to water-soluble (pee), or fat-soluble (poop) to get rid of the drug:  pharmacodynamics , what the drug does to your body to heal you and how it does it. This is for one drug. Think about a bunch of drugs where the liver and maybe kidneys do not work well.  There is a traffic jam and a couple of fights at the entry to your liver and the drugs build up in your blood.   Crash.

This is a year of my life

CPY 450 System, took me years

And so I say to you what any good or bad pharmacist would say:  “Caveat Emptor”.  Actually,  the pharmacist will put warning stickers all over the bottle and give you a packet of small print information.  Then she will make you sign that you have been counseled.

Beware the Jabberwok

Hepatitis C Research: What’s a Phase and How Can We Get through it Faster?

Hepatitis C:  Current Research Drugs

Picture your liver at the center of the Milky Way. Now, the swirling stars are treatments, some closer than others.  Drug studies are in orbit like this.  Work with me here.

Your Liver = Center of your universe.

Illustration of the Milky Way by Dianna Marquee

Illustration of the Milky Way by Dianna Marquee

Filed = Closest stars, drugs waiting on FDA approval.  The red tape wheels grind on.

Phase III = Next out, drugs being tested large-scale for safety and efficacy.  Will the virus die before you do?

Phase II = Further away from your liver, drugs shown not to kill  people when tested on a small group of sick patients. Cohort is the word.  This was me during round two of treatment.  Kind of risky here.

Phase I =  Compounds (drugs) that don’t kill healthy people crazy enough to volunteer (broke students and new parolees)

Preclinical =A blur of solar dust = test tube, computer chemical structuring, animal studies. Yep, animal testing.

When I was first diagnosed in 1991 with Hepatitis C, there was only one binary star, Interferon and Ribavirin.  Finally in 2011  came Telaprevir  and Boceprevir. That’s a long time between hits, 20 years.  Now the Hep C universe is almost getting crowded, but not yet.  The issue is safety and timelines.  The barbaric days of Interferon could be phased out (pun intended).

Phases of  Current Drug Research:  Thanks go to Dr Paul Kwo for this slide

So, this slide represents current studies, phases  and the mechanism of action (MOA).  Remember that we want at least two drugs with different MOAs in our bodies to avoid virus mutation and resistance.  The good news is that there are multiple drug candidates in each category.  For further information on any study, go to www.clinicaltrials.gov and enter the drug/compound name.  This site will also tell you if the study is enrolling patients and if there is a location close to you.  This website rocks.  Thank you federal government.

The US research system is business-based, where competition for the patent drives the process.  I’m not completely opposed to this system.  But it does have drawbacks.

Remember when AIDS researchers were competing to isolate the culprit?  France and the US,  it was crazy.  The two groups still argue about whom was first with what.

The HBO movie And The Band Played On documents government and cultural barriers to a disease connected with a cohort that isn’t mainstream, i.e. HIV and homosexual men.  I’m glad the barriers came down a bit faster with Hep C.  Initially the cohort was alcoholics and drug addicts.  But then the target audience became baby boomers.  This was 1. More acceptable and 2. A bigger pool of patients and potential profit.

Obviously the slide above is the star of this blog.    Drug companies race to be first with a new drug(s).  So why am I speaking of other things?  Because I think the days of working in a research vacuum are limited.  American drug companies say this is bad.  They claim without financial incentive, research will dry up.

But, wouldn’t it be great if companies worked together and combined research efforts?  I know, that is a big but.  I like big buts…There are novel initiatives include partnering between governmental organizations and industry. The world’s largest such initiative is the Innovative Medicines Initiative (IMI), and examples of major national initiatives are Top Institute Pharma in the Netherlands and Biopeople in Denmark.  In the USA it could be the National Institutes of Health (NIH).  We used to joke that NIH meant “Not Investigated Here”  meaning that the USA insists on its own research.  Only science types would joke about such topics. No wonder we have a reputation.

Now picture these studies sharing data.  Think of all the time and patient suffering saved by quickly identifying drug-drug and drug-disease interactions.  Think about how the winners would rise to the top.  I don’t care about the political/social overtones.  I am just thinking about patients. This is already happening with cancer research.

I have worked on this blog for a week and still can’t get it right.

Hepatitis C: Is that a Real Poncho or is that a Sears Poncho?

Mothers of invention, Theatre de Clichy, Paris...

Mothers of invention, Theatre de Clichy, Paris, 1970-1972 (Photo credit: Wikipedia)

“Look here brother,
Who you jivin’ with that Cosmik Debris?
Now is that a  real poncho or is that a Sears poncho?  Hmmm, no foolin’?”

Frank Zappa and the Mothers of Invention

Do you have a liver doctor (hepatologist) or a gastroenterologist?  Many people start out with a liver doc then over to a local gastro for long-term treatment management.  Kinda like selling your mortgage to a broker that does home mortgaging on the side but commercial financing is his bag.  I know, lame example.

Now a gastroenterologist is trained on the liver but probably hasn’t thought much about it since his fellowship at school.  Why?  Because his specialty is the GI tract (esophagus to anus).  In fact many gastroenterologists spend so much time with endoscopy or colonoscopy, they are refered to as “Scope Monkeys”.   The liver is not part of the GI tube.  No foolin’

Follow the GI tract from esophagus to anus. Then look at the liver.

Members of the two GI national associations, the American Society of Gastroenterology and Endoscopy (ASGE) plus the American College of Gastroenterology (ACG), do not attend meetings with the American  Association of the Study of Liver Disease (AASLD) and visa versa, unless presenting new research data.  But they don’t attend each other’s lectures. I know. For decades I attended the joint meetings of ASGE and ACG. It is difficult for a gastroenterologist to stay current on evolving treatments for Hepatitis C.  And these days the treatment (r)evolution is on.

Two weeks ago the AASLD and the EASL (European Association of the Study of the Liver) met in Prague to discuss Hepatitis C and:

  • Global scale intervention and control of HCV – OK
  • Prospects for a preventive HCV vaccine – OK
  • Review of new drug treatments in development such as Nonnucleoside inhibitors of HCV RNA polymerase, NS5A inhibitors, and Cyclophylin inhibitors – Important to you
  • Effectiveness of triple combinations in cirrhotics Important to a lot of you

Why do I mention this?  Here is an example of why.  Treatment of Hepatitis C is complicated and lasts a long time. The ribavirin induced anemia is treated by dose reductions based on your weight.  If your red blood cells (RBCs) drop below 10 mg/dl, Ribavirin is reduced by 20%.  If the RBC number does not increase in a few weeks, dosing must decrease another 20%.  But the dose cannot drop below 600 mg.  Now adding the protease inhibitors telaprevir and boceprevir,who knows what happens to RBCs in you?  Does the gastroenterologist know that?  Doubtful.  Does he know about the new drugs that work at different sites on the virus?  No.

Your insurance co-pay is probably the same regardless of which specialist  you visit.  Why not go with the real poncho?  BTW I couldn’t find a real poncho, only a Sears type poncho.  No foolin’

Hepatitis C: Beware the Jabberwok

 Hepatitis C:  Beware the Jabberwok

Through the Looking Glass

‘Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.

‘Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch!’

He took his vorpal sword in hand:
Long time the manxome foe he sought 
So rested he by the Tumtum tree,
And stood a while in thought.

And, as in uffish thought he stood,
The Jabberwock, with eyes of flame,
Came whiffling through the tulgey wood,
And burbled as it came!

One two! One two! And through and through
The vorpal blade went snicker-snack!
He left it dead, and with its head
He went galumphing back.

‘And hast thou slain the Jabberwock?
Come to my arms, my beamish boy!
Oh frabjous day! Callooh! Callay!’
He chortled in his joy.

‘Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.    

  

If you listen to a scientific lecture for an hour, you can begin to believe nonsense is science, but don’t.

I believe that the average Hep C patient (whoever that is) has a triple cross to bear.     1. You feel like shit on a stick  2. You have to go to unimaginable places like a liver biopsy suite and 3.You are thrown into a parallel universe where the language is almost understandable, but not really. It’s Jabberwok.

I was listening to a lecture yesterday on Hepatitis A through E. I was reading the slides as Dr. Nice Lady from pharmacy was talking.  And then I heard it:Hepatitis B and C are predominately associated with percutaneous and permucosal transmission”.  Translation:  Hep B and C can be caught through blood and through sexual contact.  Permucosal  is medical lingo for via mucous membranes.  The problem was that fifty pharmacists were about to  leave the lecture and tell their worlds that you can catch Hep C through sex.  I couldn’t let that happen so I said through the chat box “Hep C can be caught through sexual contact?  Is this new information?”  She said no, you are right to point that out, it is not transmitted that way.  So why did she say it?  The slide looked better that way.

In reality, the way one gets Hep C through sex is through rough sex and I mean rough.  Percutaneous means blood transmission.  I will pause here so that you create your own image.

Now I was willing to let it slide when she said that Hepatitis A and E were transmitted through the oral-fecal route.  In reality it is fecal-oral route.  Think about that for a moment.  But my point is that there is a lot of slightly non-true information out there.  What can you do about it?  Ask questions wherever you go.  Even if you have asked the same question before.  Remember how your doctor’s office always has that sign in English and Spanish that says Questions/Pregunta?  They really want you to ask.

Boy, did spellcheck light up Jabberwok!

Viral Hepatitis:  Keeping Your Patients Safe www.freece.com

Hepatitis C: Does “No Detectable Virus” Equal Cure Or Is It Smoke?

Am I cured or is it just smoke?

Hepatitis C cure?

 If my hepatitis C virus test shows non-detectable virus 6 months after the end of treatment, am I negative?  Will I  stay negative?  Am I cured?  In the recent past only “non-detectable virus” was declared. Now doctors are adding “cure” to the jargon.  This is with the addition of Incivek and Victrelis, and depending on the discussion.  No two clinical trials are alike and so Hepatitis C researchers use (they say utilize) sustained viralogical response (SVR) to compare outcomes.  Most trial design is by the company developing the drug.  One goal is to ask the study questions just right to get scientific and marketable answers.  “GodZillapravir had a non-detectable  SVR at weeks 12 and 24 in 85% of patients including those with mild to moderate cirrhosis”. “KingKongViracide cleared Hepatitis C virus in 94% of patients at 24 weeks including children 12 to 18 years of age”.  Which is the better drug?  You can’t tell by the claims because two different patient populations and time lines .  But they have  SVR in common.  That is why researchers use SVR.  BTW I made up the examples.  Now don’t get down on industry just yet.  Academics are accountable to department heads and medical journals.  That can be as powerful as a stockholder.

Industry is different: Stock holders in towers

When it comes to patients , the word “Cure” has emerged because research shows that if you have no detectable virus after six months, the chances of Hep C returning is about 1-2%.  And the argument is that it was never cleared, just so low that it was undetectable.

So with Hepatitis what does this mean?

Successful treatment for Hepatitis C hasn’t been available for long, so doctors are just starting to understand the long-term outcomes.  Do cancer survivors say cured?  I think they say  cancer-free for 2 years, 5 years, etc.  Am I a Hepatitis C survivor or am I cured?  Is it still a pre-existing condition?   A research site, not insurance, paid for my treatments.  But my medical records say Hepatitis C.

So at 24 weeks can I tell the insurance company that I no longer have Hepatitis C?  I can’t find the answer to that question without talking to them directly. I will wait until 2014 (I think that is the year) when they cannot cancel me for pre-existing conditions.  Insurance politics are so confusing, I am not clear if that stipulation is on the potential chopping block.  In speaking with my mental  Dr, I realize that I do not have confidence in my treatment and I am waiting for it to come back.  I am at 4 1/2 months post treatment.   I have been Hep C positive for so long, I don’t know how to have a future in which chronic debilitating illness isn’t a key player.  What is the world like with only mild hypertension and chronic but manageable depression?

Below is a good article for defining end-of-treatment terms, although it is a bit dated.  Newer drugs are not addressed but the terms are the same.

 Hepatitis C: What Is a Sustained Virologic Response or “SVR”? (From Charles  Daniel, former About.com GuideSVR) 

SVR is the closest you’ll get to “a cure” for hepatitis C.
 Sustained virologic response, or SVR, is the goal of hepatitis C treatment.  Conventional treatment (a combination of interferon and ribavirin) doesn’t  necessarily eliminate the hepatitis C virus from your liver. It can, however,  suppress the virus to undetectable levels for an extended period of time. In clinical language, this is called a “sustained virologic response,” or sustained  response. It means that during the six months after you complete treatment,  there is no detectable hepatitis C virus in your blood.                                         SVR is a good thing.
Studies have shown that with a six-month SVR (which means no detectable virus in your blood for six months after finishing treatment), relapse occurred in only 1-2% of patients. So, for every 100 people who finished treatment and attained SVR, the virus will return in only 2 of them. However, for these people, the
virus never really left. The medicine was able to eliminate most of the virus (so much that medical tests couldn’t detect it), but after treatment ended, for whatever reason the virus was able to continue replicating itself.

Early SVR is beneficial
Since the liver has incredible regenerative ability, achieving SVR
 as quickly as possible is important. This is important because some liver damage can be reversed if the cause of the damage is removed. After SVR is reached and depending on the degree of damage from the virus, the risk of hepatocellular cancer is reduced and about 25% of people see an improvement in fibrosis.

SVR compares one treatment to another. For those in treatment, SVR is the goal. However, for physicians and scientists researching new hepatitis treatments, SVR is also used to evaluate new medicines and compare them with proven therapies.
 For example, depending on the genotype, treatment with interferon alone usually achieves SVR in 15% of the patients. When interferon is combined with ribavirin in the same genotype, SVR is increased to 70% in some people.

Hepatitis C Lingo: What is a Log?

Okay, you are going into treatment.  You must understand the language of treatment progress. No one values your health more than you.

Getting information off the Internet is like taking a drink from a fire hydrant.   Mitchell Kapor

 Treatment response is a topic of great importance to me, you, and doctors.  They need  to see if the treatment is working enough to keep poisoning you.

Viral load is how to measure response. It’s done  by looking at the amount of virus in your blood. Viral load is checked before treatment,  at week 4, 12, and either 24 or 48, depending on duration of therapy, then 24 weeks (6 months) after therapy.   The response is measured in log reduction.    In fact log stands for logarithmic.  So what?  Each log corresponds to a factor of 10.  So what?  A 1-log reduction means virus decreases by 10 times; a 2-log = 100, a 3-log = 1,000, a    6-log reduction = 1,000,000 = 1 million.  Log is a way of not writing down all the zeros.  Just count the zeros gone and you get the number of viruses that died per ml of blood and went away.  Sort of.  There, in one paragraph we discussed a concept that took me some time to learn.  And you thought you would never use that math junk.

When I was in middle and high school, I had it in my head that my brain wasn’t “smart enough” for math and chemistry, even though I skipped kindergarten and the 2nd half of my senior year.   So I avoided the hard sciences.  Remember I was still GOD, grown up on duty, at my house. Then in my 20s, I went to college and I decided I didn’t want to fear math and chemistry any more. I took inorganic chemistry with algebra on the side to understand the language of thermodynamics.  This is an example of how my childhood perceptions always played down my abilities even though my family said I was smart (which I loved but didn’t believe) . I graduated from pharmacy school at 30,  then went back for a Dr. of Pharmacy in my 50s (while traveling around the country for work and, unaware that Hep C was dragging me down).

Why am I interjecting these little stories in the middle of scientific drama?  Because there is no scientific drama!

All measures must have units:  pounds of pressure per square inch (PSI), miles per gallon (MPG), ears of corn per stalk (one).  Notice the word per in each. The  Hepatitis C virus (HCV) is number of copies of the virus per ml of blood. The hepatitis C virus, like all viruses, cannot reproduce by itself. It must first infect a living cell, such as the hepatocyte, and take over the cell’s “machinery.” Using the genetic information in your cell, the hepatitis C virus is able to make copies of itself which can go on to make more copies.  The virus is measured in copies per ml of blood.  I know, weird.

Lindenbach B, Rice C (2005). “Unravelling hepatitis C virus replication from genome to function”. Nature 436

BTW, kids in Middle School know this stuff.  Amazing.    We will talk about RNA another time.  I know you can hardly wait.
