LIVING with CF--updates from NACFC 2014

The NACFC discussions that receive the most attention are typically geared toward the scientific developments.  Obviously, I care deeply about progress toward a cure, but I try to balance those technical talks with some information on ways that we--as a community of patients and families, might be able to have a real positive impact on health through the informed choices we make today.  

The Relationship Between Exercise Capacity and Glucose Tolerance in a Pediatric CF Population Not Diagnosed with Cystic Fibrosis Related Diabetes.
Foster, K.E. Cincinnati Childrens Hospital

Hopefully, most people recognize that regular exercise can provide numerous health benefits to ANYONE.  Regular exercise is especially important for those with CF.  CF related diabetes (CFRD) is a frequently occurring complication of cystic fibrosis, and is associated with greater decline in lung function, poorer nutritional status, and lower life expectancy.  In this discussion, Foster examined the connection between exercise capacity, and the ability to successfully regulate blood sugars.  

Foster measured both exercise capacity, and glucose tolerance (via oral glucose tolerance testing) in 50 patients, and discovered a correlation between low exercise capacity, and increased 2 hour blood glucose values.  This suggests that patients with low exercise capacity have poorer glucose tolerance. Foster speculates that working to improve exercise capacity may help delay the onset of CFRD via improved blood sugar control.  

As you can see in this slide, there isn't hard data on this correlation, but rather, a strong suspicion that blood sugar control may be improved with regular exercise--leading to a delay in the onset of CFRD.  

Since I personally believe strongly in the value of exercise in health maintenance, I want to hammer the point home with one more discussion:

Yoga Improves Posture and Muscular Performance in Adult Persons with Cystic Fibrosis
Scott Russell, University of Southern California

"Persons with cystic fibrosis are prone to posture dysfunction, in part due to pulmonary hyperinflation and chronic coughing which can lead to injury, chronic pain disorders, vertigo, headaches, balance dysfunction, increased risk for vertebral fractures, and loss of physical functioning.  The purpose of this study is to investigate the effects of Hatha yoga on posture, neuromuscular performance, and self-reported psychometric measures."

In this small study, patients agreed to participate in twice weekly, 90 minute, outdoor yoga sessions over the duration of 8 weeks.  A couple of important points worth noting:

1) Strict infection control guidelines were observed--persons with CF were each provided with their own (vs. shared) yoga props, and were equipped with hand sanitizer gel, tissues, etc...  Yoga was also practiced in an open, outdoor area and the "6 ft. rule" was observed due to multiple CF participants in the same class.  Of course, if you decide to take up yoga, it is unlikely that you would be surrounded by other CF patients, and such strict precautions may not be required.  

2) Russell made sure to note that practice of yoga for CF patients often requires modification of poses to avoid the "head down" position, or "inversions," which can aggravate acid reflux/GERD for many patients.  It is very important to educate the instructor about the need for these modifications, since an increase in acid reflux symptoms would be an undesired effect, and could lead to a worsening, rather than an improvement in lung and postural health.

This is hard to read, but it says that the primary aims of this study are to discover 1) the effects of yoga on pulmonary functional, and chest wall mobility, 2) the effects on physical function and posture, and 3) effects on scapulothoracic posture.   Self-reported psychometric measures regarding quality of life were also recorded.  Ultimately, Russell wanted to determine the SAFETY and POTENTIAL BENEFITS of yoga for persons with CF.

These are examples of the "head down" positions that should be AVOIDED if you suffer from acid reflux/GERD.

Here we see an example of a modified downward-facing dog position.  Note that the trunk and head stay parallel to the ground, rather than the typical head down positioning.  A few extra props may be helpful for the appropriate modifications

Russell provided an example of the poses used by the instructor in the intervention.  

The results showed an improvement in chest wall excursion after 8 weeks of the yoga intervention.

Scapular positioning was also improved--positive effects on posture. 

Patients showed improvements in the "Sit to Stand Test" and several other fitness measures.

Patients had improved self-reported attitudes toward their weight/body image.

As I mentioned earlier, this was a small study, but I appreciate that we are discussing topics like this AT ALL, so I wanted to report on it anyway!  It is my blog, and I do what I want! :)

You might even consider doing your own "future investigation" on whether yoga is something that might be beneficial for you, remembering to follow the appropriate precautions.

In conclusion, Russell reported that in this phase 1 feasibility study, yoga improved posture, chest wall excursion, lower extremity muscle performance, and the self-reported body/image perceptions.  

In my opinion, exercise is an extremely underutilized tool to improve health outcomes for CF patients...and basically everyone else (in the U.S., at least!).  While we don't have a ton of evidence from a large scale study on the benefits of yoga specifically, there is PLENTY of evidence regarding the benefits of regular exercise.  Maybe yoga doesn't sound so great to you...and that is OK!  The best type of exercise will be something you enjoy, so that it will be done consistently.   Since no new breakthrough therapies are hitting the market today...why not try EXERCISE as a natural, effective way to provide multiple health benefits?  I know that when I recently attended a "restorative yoga" class with my friend Savannah, I left the class feeling awesome--both physically and mentally.  I think that the attention paid to breath control in yoga makes it a particularly attractive option for patients with pulmonary dysfunction.  

The next talk I want to summarize deals with a topic that some people wouldn't consider CF related at all, but I will argue that mental health issues can have deep and long lasting effects on health for both CF patients themselves, as well as their family members.  As a CF mom, and a member of the Patient Engagement Advisory Committee for the CF Foundation, I've come to realize that mental health simply cannot be segregated from our physical health.  Babies and young children are absolutely dependent on their parents for everything from proper nutrition to adherence to their prescribed CF treatment regimen.  If a caregiver is struggling, negative effects can ripple throughout the family, and ultimately affect the child.  When I was a new mother struggling with Brady's CF diagnosis, I would have never even considered bringing up my own mental health struggles with Brady's CF clinic team...even though I realize now that I probably should have.  It didn't seem like the time or place for me to air my own concerns about how out of control I felt over my emotions, and life in general.  Parents of children with special needs often put their own problems on the back burner, and find the topic to be too personal and painful to discuss.  I struggled with depression, crippling anxiety in regard to clinic visits, and persistent sleep problems during Brady's infancy.  I didn't want to admit that this time in my beautiful son's life was a really dark and scary period for me. I just figured that because CF sucks so much, I would probably never feel really good again, and that the depression and anxiety were par for the course.  I'm sure that my struggle is not unique, and that many of you may potentially relate to the helpless state I found myself in.  

What Healthcare Providers Need to Know About Postpartum Depression (Associated with Newborn Screening), But Were Afraid to Ask.
Audrey Tluczek

This discussion dealt particularly with postpartum depression associated with a CF diagnosis following newborn screening.  The speaker explained that she uses the term "postpartum depression" simply because it is defined by the onset of depression symptoms coinciding with the birth of a child. Unfortunately, for families with a newly diagnosed infant, that early period can be so overwhelming and scary.  Many would probably consider postpartum depression/anxiety a problem exclusive to mothers--but when management of a chronic disease in a child is required, it can be just as pronounced in FATHERS, GRANDPARENTS, or anyone that is functioning as a care provider for the child.  Tluczek discussed the need for more formal depression screening as a part of the regular clinic visit for families with newly diagnosed infants, and training of the clinic care team to provide useful interventions.

Clinic teams are becoming aware that mental health assessments NEED to become an integrated part of CF care.  Unfortunately, many members of the care team may not be formally trained to recognize the symptoms.

For family members exhibiting signs of depression in association with care of the infant, treatment options can include psychotherapy, support groups, medication, and hospitalization for the most severe cases where the health of the individual or child is believed to be endangered.

This is important, because depression negatively impacts parent/child interaction.

I didn't realize how much my own mental health might be negatively affecting the precious child I wanted so desperately to protect.

Having a good relationship with a stable partner, family support, and the ability to provide for the basic social and economic needs of the family were found to be important factors in lessening the negative effects of post diagnosis depression. 

The CF Foundation recommends that mental health screenings should be a part of the regular clinic experience for both CF patients, and their families.    
In this day and age of comprehensive care, I think it is so important that we feel that we can discuss depression, anxiety, OCD symptoms, or any mental health concerns with the CF care team.  Looking back, I certainly wish I hadn't suffered in silence for so long.  It is equally important that care teams are appropriately trained to recognize the symptoms of mental health issues, and provide options for treatment that may include referral to an outside professional.  This topic is simply too important to remain taboo.  It should be noted that while this talk focused specifically on postpartum depression, mental health concerns can come up at any time, especially with the demands of chronic disease management.  These issues are important to address at any stage of life.

I know many of my readers tune in to the blog for science updates.  I hope I haven't tarnished my rep by devoting this entire entry to the fine art of living and thriving with CF.  Tomorrow, I plan to return to the cutting edge...and honestly, I need a night to sleep on the information I heard this morning in Symposium 8: Gene Editing Strategies for Therapy and Research.  I believe that the future cure for EVERYONE with CF--regardless of their mutation, may become reality through one of techniques discussed in that room.   Until tomorrow...

Updates from the NACFC--Thursday Oct. 9th, 2014

I wait impatiently for the NACFC each year.  This is my 4th year in attendance, and I love having the opportunity to share the newest information with all of you.  This year, I flew to Georgia a few days early, to spend some time with another CF family I have become close to via social media through the last several years.  As you know, CF is an isolating disease…and I typically take every chance I get to make that real life contact.  BE WARNED—if you invite me to visit—I might actually do it!  Thank you to Teresa, Savannah, and Sam, who spoiled me with the finest in Southern hospitality, and will have a permanent place in my heart. 
Teresa and I drove from Savannah to Atlanta on Wednesday afternoon, retrieved our registration bag o’ goodies, and began networking with the arriving attendees at the preferred meeting space—i.e., the bar.  I can’t tell you how good it feels, to be surrounded by so many brilliant professionals from around the globe working to cure CF.  For me, the NACFC not only expands my knowledge, it also expands my heart.

If you follow CF research, you are likely aware that Vertex published data from their phase 3 clinical trial of a VX-770/VX-809 combination therapy for homozygous DF508 patients several months ago. The results from the study showed modest benefits in lung function and small decreases in sweat chloride levels.  To be honest, after the FANTASTIC results experienced by most G551D/gating mutations with Kalydeco alone—the results from the combo trial (while positive) were disappointing to some.    Vertex reports that they plan to apply to the FDA with a new drug application in “the last quarter of this year.”   There has been plenty of speculation on whether or not the FDA will consider the benefits of the combination therapy statistically significant enough to approve the drug for marketing.  I am hopeful...but why haven’t we reached a greater level of improvement with the combo for DF508?  Theoretically, an increase in CFTR protein trafficking to the cell surface (via the corrector action of VX-809), plus an improvement in chloride channel open probability (via the potentiator action of VX-770) should produce a more robust improvement.  Dr. Deborah Cholon thinks her data can help provide an explanation for the “smaller than hoped for” treatment effect seen with the combination of these two molecules.

Potentiator VX-770 Abrogates Pharmacological Correction by Destabilizing VX-809 or VX-661 Rescued DF508 in Airway Epithelial Cells.

First of all, let’s review.  The DF508 mutation has several issues contributing to the overall protein dysfunction—

1) Decreased stability in the folding mechanism of CFTR—resulting in decreased trafficking to the cell surface

2) Gating defect for any protein that does manage to reach cell surface (similar to what is seen with G551D) the channel doesn’t open and close properly—“rusty gate.”

3) Increased cell turnover at the cell surface (any protein that does successfully arrive in the correct place in the cell, rapidly “unravels” and doesn’t actually become a functional Chloride channel).

When researchers began exploring how to correct CFTR function for DF508, they quickly realized that the road would not be nearly as straightforward as it had been for the gating mutations.  To achieve a robust amount of functional CFTR, multiple problems must be overcome—requiring multiple compounds to get there.  Individually, both VX-770 and VX-809 produce the desired action on lab cultured cell lines.  Unfortunately, Dr. Cholon discovered that for the DF508 mutation, chronic exposure to VX-770 had a destabilizing effect on the amount of mature CFTR protein able to be “rescued” (successfully mature and reach the cell surface).  Furthermore, exposure to VX-770 also increased the rate of turnover (the unraveling process), ultimately reducing the amount of CFTR available for chloride transport.  The higher the dosage of VX-770, the larger the destabilizing effect on DF508.
Exposure to VX-770 reduces CFTR rescue (maturation)

Also reduces the stability of the protein--leading to premature unraveling.

The negative effect of VX-770 exposure on DF508 was also observed in combination with the other corrector compound in development at Vertex--VX-661.


Researchers have been focused on finding a great corrector compound for DF508, but what they didn't realize is that "one size does not fit all" when it comes to potentiator action. VX-770 works great for gating mutations, but "disagrees" to a certain extent with DF508.

Even with this crappy news--the fact remains that an overall positive treatment effect was still observed in the combo trial:

Relative improvement of 4.8% in FEV1 with combo treatment

Decreased rate of hospitalizations and IV antibiotic use with use of combo treatment for homozygotes.

Fewer exacerbations observed in trial group treated with combo therapy.
I believe that Dr. Cholon's research does indeed provide some valuable insight into the smaller treatment effect seen in the combo trial.  I think there there is still a decent chance for FDA approval of this combo therapy, but the hunt for a more suitable potentiator for DF508 is certainly ON.  In the Q and A portion of this talk, Dr. Cholon described that while VX-770 may act negatively on the maturation and stability of CFTR, the molecule may still provide "alternate benefits" such as the improved regulation of bicarb (which can help normalize pH in airways--increasing the lung's own innate killing power of invading organisms), and subsequent reduction of the "bacterial load" in the lungs.

I hate to report this as my first piece of Conference news, but there were several talks today, including an entire afternoon symposium session, focused on the negative effect of VX-770 on DF508 this year, and I'm not good at sugar-coating (Other titles along the same lines presented this afternoon:

Potentiator Ivacaftor Abrogates Pharmacological Correction of DF508 CFTR--Gentzsch,

Mechanisms of Potentiator Inhibition of DF508 CFTR--Bridges, Opposing Effect of the VX-770 

Gating Potentiator on the Corrected DF508 CFTR Function and Processing--Lukacs.

This info is certainly NOT what I wanted to hear or report, but it is also NOT A REASON TO FREAK OUT. The results of the combo trial were published months ago, and showed that the treatment effects of the combo were not as robust as we had hoped.  At least now we have some idea WHY that is happening.

Moving on...

I didn't have to wait long for more positive news.  Later in the same workshop this morning, we heard from R. Fitzpatrick from The Flatley Discovery Lab (a privately funded research facility dedicated exclusively to finding new potentiator and corrector compounds).

Progress Toward a CFTR Modulator System

The Flatley Lab has high-throughput screening capabilities, and has tested over a million individual compounds, and more than 36,000 novel compounds for ability to positively affect CFTR rescue and open channel probability.  Their research has already yielded several potential drug candidates.


Potential compounds for development. 

Flatley Labs has found a compound with similar action to VX-809 called FDL169

And they are moving forward with development.

They have also discovered several new potentiator candidates, that could be utilized in a future novel combination therapy.  You may notice that the potentiators shown on this graph don't quite reach the level of benefit that is seen for VX-770 for G551D, but they may still prove superior to VX-770 if the DESTABILIZING effect described earlier on DF508 can be avoided. 


Sorry this is so hard to read!  The slide shows that Flatley Labs favored potentiator compound--FD2033129, does NOT inhibit CFTR correction in DF508.  This is reason to believe that it may be a more feasible molecule for use in combination with a corrector for DF508.

Flatley Discovery Labs is hoping to initiate trials on some of their discovered compounds in "December of this year, or January of next."  They are already discussing combining multiple correctors with their novel potentiator candidate to create a "second generation" combo therapy for DF508.

The last talk I want to summarize in this entry was given by Fred Van Goor from Vertex:

R117H is a Residual Function Mutation That Is Potentiated by Ivacaftor

As you may know, R117H is a mutation where the CFTR protein is observed at the cell surface, and SHOULD be effectively potentiated by Kalydeco.  In trials, Kalydeco was found to have a "less statistically significant treatment effect" for this group, and R117H was subsequently excluded from the FDA's expansion of approved mutations earlier this year.  Van Goor proposes that the smaller effect observed in R117H as compared to other gating mutations is NOT a consequence of diminished action of Kalydeco, but rather, a function of the milder nature of the R117H mutation itself.


R117H is generally considered a "milder" mutation.  Many patients with this mutation are pancreatic sufficient.  Serious lung dysfunction often doesn't present until later in life within this group, and I know of several patients with this mutation that weren't even diagnosed until adulthood.  


Patch-clamp studies show that Ivacaftor increases the frequency of channel opening of the CFTR protein at the cell surface for the R117H mutation.





Van Goor went on to show that treatment benefit to R117H could be increased by the addition of Lumacaftor (VX-809)
All signs indicate that R117H is a good candidate for both Kalydeco monotherapy, as well as combination therapy.
If Kalydeco is working so well for R117H, then why were smaller improvements in FEV1 observed in clinical trials?  Van Goor suspects that this group was unable to achieve the massive gains in lung function observed in the other gating mutations, simply because the lung function of patients in this group was already very good to begin with.  You can't gain 10% lung function if it has never been lost in the first place.  To further illustrate this point, let's consider my son Brady's response to Kalydeco. Brady has DF508 and G551D, and I have written VOLUMES about the benefits we have observed in him: disappearance of serious sinus polyps, huge drop in sweat chloride levels, increased energy, increased BMI and nutritional status, etc...  BUT, Brady did NOT see a huge improvement in lung function because his lung function was good to begin with.  The absence of a huge improvement in FEV1 DOES NOT mean that the drug is not working incredibly well.  You can't keep going up if you are already near the top!  Based on the evidence presented today, and over the last several years, I agree whole-heartedly with Van Goor's explanation.  According to the press release published by Vertex today,

"Based on the Phase 3 data, Vertex submitted an sNDA in the U.S. and MAA variation in Europe for approval of ivacaftor in people with the R117H mutation. Vertex's sNDA for the use of ivacaftor in people with the R117H mutation will be the subject of an FDA Advisory Committee Meeting of the Pulmonary-Allergy Drugs Division on October 21, 2014. In the United States, Vertex is seeking approval of ivacaftor in people ages 6 and older with the R117H mutation."

I am very hopeful that we will see an approval for R117H soon. There is so much more to say, but it is time to sleep so I can do it all again in a few hours!  Tune in tomorrow for news about:

Conflict Free Zone

I do not have ANY AFFILIATIONS that I need to disclose.  I am not employed by anyone.  I hold several volunteer positions within The Cystic Fibrosis Foundation (Great Strides Spokane, WA Chair, Idaho State Advocacy Chair, Patient Engagement Advisory Committee member).  I have zero conflicts of interest.  In fact, my only real interest in this topic is to see my child, and others that need it, have access to Kalydeco and other new therapies that might be available soon to treat CF.  This entry is simply the way that I see the flood of recent media attention, as a parent of a child with CF. Brady has been taking Kalydeco since February 10, 2012.

I can feel the storm brewing as Vertex's VX-809/VX-770 combo approaches the doors of the FDA. Kalydeco, The CF Foundation, and the astronomical price of this little blue pill have also been very hot topics in economic, pharmaceutical, and medical journals lately. Bloggers all have their own point of view on the issue.  I think I know a lot about it, so I'm offering mine--

The Issue--The Price of Kalydeco.
First of all, let me say that Brady has been enrolled in the Vertex GPS (patient assistance program), since his 6th birthday.  The case managers at Vertex have been really phenomenal to work with.  They are total experts at getting things done with insurance.  Nothing but good things to say about this program. The tricky part is that you must fall under the FDA approved guidelines to qualify for this program.  We pay $15/month out-of-pocket for Kalydeco.  Seems too good to be true.  Before Brady turned 6, Kalydeco was covered by the private insurance (Blue Cross/Blue Shield of Idaho), that we have through my husband's employer (Yes, we got insurance coverage, "off-label" for Brady at age 4 1/2.). Even though the approved label has now been expanded to several other gating mutations, and patients in other countries, the price of Kalydeco has mysteriously climbed over $6K/month over the last 2 1/2 years. Why is that? According to Vertex, they set the price of Kalydeco based on "the perceived benefit for the limited patient population."  Shouldn't MORE patients lead to a LOWER price?  Ha!  Not in a market economy!

The truth is that Vertex, as a company, took a huge blow with the recent failure of their hepatitis drug Incivek.  When Incivek was approved by the FDA in 2011, it generated huge sales for Vertex--estimated at around $951 million for the first 6 months it was on the market.  Their sales came to a screeching halt, as Abbvie and Gilead came out with newer, superior Hepatitis drugs, making Incivek virtually obsolete.  This Forbes article discusses the financial impact on this failed Hep C drug, which prompted Vertex to cut 15% of their workforce.  The article describes how "This has created an enormous gap in future earnings and Vertex needed to cut costs to make up for this loss."

Vertex is a FOR-PROFIT company in a free market economy.  They want to remain profitable as a business, so they can keep their doors open.  Vertex is using the sale of Kalydeco--their one and only successful drug, to make up for their losses in other areas of research, and close the expected earnings gap.

How Can Vertex Do That?  
Why Doesn't The CFF Make Them Charge Less?

Vertex has set the price of Kalyeco so extremely high, that it has delayed access to the drug in some countries (Australia and Canada most notably) and caused push-back from Medicaid in Arkansas.  Lately, I have been reading some criticism on the role of the CFF in this mess, and it upsets me.  This is what I know.
The Cystic Fibrosis Foundation has invested millions of dollars into Vertex (formerly Aurora Biosciences). This money has been used mainly to set up and operate a high-throughput screening lab, to allow scientists to screen thousands of compounds in search of those with the ability to restore chloride channel function. When compounds are discovered that enhance chloride channel activity, they can then be tweaked and further devoloped, tested on human cell lines in the lab, and eventually progress toward clinical trials in humans.  That is exactly how Kalydeco was discovered.  The work done by Vertex with the money invested by The CFF has been nothing short of incredible.  This is the cutting edge of genetic science.   Our understanding of CFTR function has been enriched enormously by their work, which has really set the stage for the whole "small molecule treatment based on mutation class" era that we are entering today.  Even if Vertex hadn't uncovered a blockbuster compound like Kalydeco...we still would have gotten our money's worth.  They did EXACTLY what they were given money to do, and they did a damn good job.  Never in the negotiation did The Cystic Fibrosis Foundation have the power to demand where Vertex must set the price of a drug--if it were to be discovered.  The CFF hoped they would find ANYTHING at all...and they found Kalydeco. Amazing!  At that point in time,  the CFF was knocking on doors begging pharmaceutical companies to do any CF research at all.  We didn't hold the power, or the stock, to have any real sway in setting the price point for Kalydeco.  That isn't how the free market operates.  Honestly, investing in research, there are MANY more failed projects than success stories.  The CFF has put millions of dollars into numerous companies over the years to do research that resulted in absolutely nothing.  That seriously happens all the time! Sometimes all we learn from our investments is what DOESN'T WORK.  Of course, some of those research risks also led to drugs like Pulmozyme, Tobi, and Cayston.  Ahhhh science--strikes and gutters. We paid Vertex to do the research so that it might not take their company out of business if they happened to roll a gutterball with their CF research.  Instead, they rolled a strike by discovering Kalydeco.

BOOM!
The money invested by The CFF into Vertex served to take away some of the huge financial risk of entering the realm of CF research.  Without development incentives, companies wouldn't bother getting involved at all.  The CF population is very small, and it is much more PROFITABLE to be involved in research for a cancer, diabetes, or cholesterol medication--that could potentially be prescribed to MILLIONS of people rather than a few thousand.  The fact that we are having this conversation means that the miracle drug exists...and falls into the "good problem to have" category, as far as I am concerned.

The Unfair Part

The major problem I have with the way this has played out, is that access discrepancies  leave some CF families PAYING TWICE.  The CF Foundation funded a significant portion of the the cost to develop Kalydeco, and the CF community works hard to keep money flowing to The CFF, through grassroots fundraising.  CFF execs also work hard to bring in millions in major donations. It just feels wrong and dirty that the price of Kalydeco is so exorbitantly high, that some eligible patients may never get the chance to try it. In the words of Dr. Francis Collins, "Drugs that are lifesaving, ought to be affordable." It makes me so sick to think about the patients in Australia, and other parts of the world that could benefit from Kalydeco, but don't have access to it because of cost negotiations. After all, it isn't the CF community's fault that Vertex's Hep C drug failed!  Why are we being saddled with the burden of recouping totally unrelated losses?  Because that is the way business works. Vertex charges $300K/yr for Kalydeco simply because THEY CAN. I obviously have some mixed feelings about Vertex.

The Good--The scientists couldn't be any higher on a pedestal in my mind...
The Bad--but I have issues with some of the executive behavior.
The Ugly--Vertex execs have made multi-millions on questionable stock exchanges, and are being investigated by the SEC.  Some patients that desperately need the drug, still don't have it, because of price issues.

Rumors About "Conflicts of Interest" for The CFF

The Cystic Fibrosis Foundation owns a small % of the rights to Kalydeco and receives royalties on its sale. The money that comes in from royalties is re-invested in further scientific research.  The CFF invested $75 million in Vertex to develop Kalydeco.  The CFF then sold a portion of those rights for $150 million (double our original investment!), investing that money in further projects with Vertex, and new projects with pharma giants Pfizer and Genzyme.  Some people argue that it is unethical for The CFF to promote the sale of Kalydeco, which it now considers the standard of treatment for approved mutations, and receive cash royalties for every astronomically priced prescription that is filled.  This is an investment model that The CF  Foundation has used in the past, that has successfully generated millions for new research.  In fact, $20 million of the original $75 million that was invested in Vertex came from the royalties that The CFF made from sales of TOBI. Was THAT wrong? And I will argue that The CFF recommends Kalydeco as a standard of treatment because the science shows it is by far the most beneficial treatment for these eligible CF patients--not to line their own pockets.  It would be absurd if The CFF DIDN'T recommend Kalydeco!  This is certainly not the first time The CFF has used royalties to further scientific discovery, and it has resulted in some amazing improvements to treating CF.   This "venture philanthropy" model is precisely what sets The CFF apart from other disease non-profits.  The CF Foundation may not have the power to demand that Vertex charge a lower price, but they can choose to broaden their investment portfolio, in hope of giving Vertex some direct competition.  In this article, Dr. Beall says,

"Without the financial support of the foundation drugs such as Kalydeco would never get on the market".  He rejected the idea of using the royalty money to help patients pay for the medical care, noting that foundation needed the money to entice large drug companies such as Pfizer to get involved in risky cystic fibrosis drug research.  He said he could only express his concern about the price and invest funds with other companies that might develop competing drugs that someday could bring the price down.  

Bringing competitor potentiators and correctors to the market is how we are going to influence the price of treating CF, and The CF Foundation has been absolutely masterful at not putting all their eggs in one basket. The CFF now has numerous partners like Pfizer, Abbvie, N30, and Galapagos working to bring better, competitive compounds to market.  Vertex got burned when competitors made their Hep C drug Incivek obsolete...the same exact thing could happen to Kalydeco or the VX-809/VX-770 combo.  The CF Foundation is working to lower the cost of these treatments in the most effective, realistic manner our system allows.  And I honestly don't see the conflict of interest in re-investing a portion of the sale of Kalydeco back into research.  As a parent, and "paying customer," I would rather see at least a small part of the monthly payment from our insurance go back to The CFF for continued research.  I think that is the investment that will provide Brady with the greatest returns--in the form of a long healthy life.  The alternative is to see 100% of the money go to Vertex, and miss out on those research opportunities.  It isn't going to lower the price of Kalydeco a single penny if The CFF sells their rights.  It would just be someone else collecting the check at the end of the day.  You know how many Great Strides walks and family bake sales it would take to raise the $150 million in royalties we have received from Kalydeco?  I say we keep the damn money and put it right back into the laboratory.

Speaking of Fat Checks...I've Heard Some Complaints About the Salaries of The CFF Executives Also. 

The CFF has been lead by CEO Dr. Bob Beall, and COO Rich Mattingly for well over 30 years.  These men have dedicated their lives and careers to creating hope, where there was none.  In terms of non-profit disease organizations, The Cystic Fibrosis Foundation is the envy of the industry.  They have had more SUCCESS in changing the course of the history of a genetic disease than some people believed possible. That success came from a radical departure from the typical non-profit operations.  That success came from huge risks that others weren't willing to take.  That success came because our leaders are absolutely extraordinary.  Charitywatch.org reports Dr. Beall's salary at slightly over $1 million per year.  I believe that he is worth every single penny.  We simply wouldn't be where we are today without their unique vision and never quit attitude.  I am  not interested in a mediocre leader for this organization.  I want to cure this disease.  Our leadership is NOT where we want to settle for second-rate, and try to pinch pennies.  Just because it is a non-profit organization, doesn't mean that The CFF doesn't compensate it's own employees, and we want the best!  Of course, there are thousands of individuals that contribute great value to the organization on a volunteer basis.  The executive team, however, is made up of top notch professionals that have made curing CF their entire career.  Criticize all you want, but the fact is, that Dr. Beall's salary is a mere drop in the bucket compared to the multi-millions he BRINGS IN to The CF Foundation every year.  He secured $20 million from Bill Gates alone, in 1999, to get the initial project (The Aurora Project) with Vertex (formerly Aurora Pharmaceuticals) off the ground.  I will argue, until I am blue in the face, that the CFF execs are a HUGE NET WIN for the CF Community.  I admire them as heroes, and can't imagine trying to put an actual value on their worth.  If we want the best in the business, we have to be willing to compensate them appropriately.  And after 30+ years at the same organization, I can't imagine anyone accusing them of staying with CFF to get rich.  INDUSTRY is where the big money is made with expertise like that.  I stand in firm defense of The CFF execs, and their SUCCESSFUL venture philanthropy business model.  If you take Kalydeco, Pulmozyme, Tobi, Cayston, prescription digestive enzymes, or basically any other drug developed to treat CF, you should thank Bob Beall, Rich Mattingly, and Preston Campbell at the CFF. They are responsible for extending people's lives.

Back to the Value of Kalydeco  

Lastly, I've been reading plenty of speculation on the effectiveness of Kalydeco, mostly in financial papers.
Is Kalydeco really THAT good?  Is it really worth the price if patients don't experience close to a "cure"? What about the side effects?

Here is the deal--just as no two cases of CF are alike (even with siblings with CF), no two patients will respond in exactly the same way to Kalydeco.  One big factor is how much "permanent damage" or bronchiectasis, the patient has sustained.  When a patient (with a gating mutation) begins taking Kalydeco,
their Chloride transport is suddenly turned ON.  This new found functioning at the cell surface causes a flush of hydration to those tissues and can stir up some mucous plugs and pockets of infection that may have been hanging out for DECADES in some patients.  For most adults initiating Kalydeco, they go through a period of time that can last from several days to even a few months where their body sort of PURGES old mucous and adjusts to the new mode of operation.  Stirring up these old infections can cause fever, flu-like symptoms, almost unbelievable amounts of flying mucous, and an overall feeling of unwellness (from what I've heard).  HOWEVER, once the initial clearing phase is over, patients report deeper breathing, more watery mucous, and decreased coughing.  In general, well-being is IMPROVED when the body's chloride is functioning more normally.

Imagine a 40 year old man that had smoked cigarettes daily since the age of 15.  If he stopped smoking one day, his body would adjust, and he would experience some HUGE benefits to his breathing ability.  His lungs would start to clear some of the gunk, and greatly slow the rate of decline of lung function.  Still, he may have already developed some emphysema or COPD, and will never breath like someone who had never smoked a day in their life.  He may still need medications to treat his lungs, and may still succumb to illnesses like pneumonia more easily.  He may still, eventually die of lung related problems...even though he stopped smoking.

Hopefully, we don't have many smokers in the CF community, but you can relate the huge spectrum of responses to Kalydeco to this scenario, and understand that the type of maintenance therapies required to manage each person's disease from that point forward will be completely unique.  Scientists are learning more every year about how Kalydeco impacts the body, and have broadened their scope of interest beyond the lungs.  They are looking at how Kalydeco impacts digestion, liver function, sinus function, development of CFRD, etc...  I feel compelled to attend the NACFC each year to stay updated on the newest Kalydeco research.  So far, the more I learn, the better it gets.  Here are some of the highlights--

You don't need to be a scientist to read this graph.  I burst into tears the first time I saw it. Huge increase in FEV1% predicted almost immediately upon initiation of Kalydeco--maintained fairly evenly for the course of the trial.

Another clear example of the power of this drug.  We have NEVER had anything in our hands with the power to change sweat chloride levels--which are (at least loosely) linked to CFTR function.  This graph shows a huge decrease in sweat chloride for patients taking Kalydeco--again, sustained through the course of the trial.
This is a summary from the GOAL study, which examined different study endpoints than were reported on in the phase 3 trial.  Report represents longer term data...shows continued awesomeness.  

I saw data for the first time at The NACFC 2013 that patients experienced a decrease in hospitalization rate with Kalydeco.

Patients taking Kalydeco also have 35% reduced odds of culturing positive for Pseudomonas.

Ivacaftor has been shown to normalize the pH in the lung, enhancing the body's own natural lung defense--proper pH promotes the lungs own "killing power" of invading bacteria.


Ivacaftor has also been shown to normalize pH in the intestines, enhancing the function of the digestive enzyme replacements that most CF patients rely on at every meal.  The enzymes are designed to dissolve when their environment turns from acidic to basic.  This is supposed to happen at the beginning of the small bowel.  CF patients often have trouble achieving that basic environment because of impaired bicarb channel function (bicarb "neutralizes" the acid, changing the pH in healthy individuals).  Many CF patients take acid blockers of some kind to aid the body in achieving a basic intestinal pH.  Patients taking Kalydeco saw intestinal pH normalize, thereby bringing their bodies into the zone where their enzymes would work at their absolute best.  

I am hoping to hear more information on Kalydeco's ability to impact pancreatic function and the development of CFRD at upcoming Conference!  Still an unknown, but an exciting prospect!
Beyond all this "official data," you can read the most recent update on Brady's personal response to Kalydeco in this previous blog entry.

Bottom line: If you want to question the effectiveness of Kalydeco, please bring some real data to back it up. Published information, and what I have seen personally in Brady and the many others I have connected with on Kalydeco, show a highly effective, life-changing  drug for eligible mutation types.  I have heard individuals bring up the fact that those on Kalydeco still showed some decrease in lung function over time. That is very likely true, but the rate of that decline has been cut in HALF.  The long-term data presented at the European Cystic Fibrosis Society Conference still paints a pretty rosy picture, as far as I am concerned. Patients with COPD, asthma, or any other lung disease may experience a decrease in lung function over time also. We may not have achieved perfection with Kalydeco...but we have major improvement.  Patients taking Kalydeco first saw a huge jump in lung function, followed by a reduction in the rate of decline.  Win. Win.

Closing Thoughts
*I believe that The CF Foundation is fighting exorbitant drug pricing in the best possible manner within our system--by investing in competition.  If we want to be in the game at all, we have to follow the free market rules, and you've got to play to win!  I will also argue that CFF execs are worth every penny they are paid.

*Kalydeco wouldn't exist without the venture philanthropy model--which has fueled a large part of the CFF's drug development success.

*Vertex is behaving as many businesses do (despicable, but not overly surprising).  They have a blockbuster in their hands now with Kalydeco, and a recent failure with Incivek.  As far as anyone knows, they haven't done anything illegal.

*Lastly, I could never describe how deeply I appreciate the work done at Vertex Pharmaceuticals.  I mean, I have their molecule tattooed on my left foot.  All I am saying...is that it is my one and only tattoo, and I have plenty of empty real estate where I can place the next amazing compound that comes around!  I would love nothing more than to see my precious Kalydeco become obsolete (and cheap) when a competitor drug maker eventually comes to market with an even more effective potentiator!  Please be respectful in your comments, and remember that I represent no one but myself.
