Rare Afflictions: Medicines or Markets - 03


MOVE OVER MEDICINES.. time for Patents in Markets

Model Most Sought


An informative point is made by Downton Abbey’s co-producer Neames when he relates that the country estate to which the family goes in A Journey to the Highlands was first built and owned by the Scottish* Campbell family. Built, said he, for prestige.. to umn show off.. their power and influence thereabouts. 

*A.J.P. Taylor’s prefaced word pertaining correct Scot usage.

What strikes viewers is the enormity of everything, huge gardens, a stone-walled castle with its bridge over some former moat leading to and from the entrance and then that high and wide room whose walls are festooned with rifles and gun arrays. Point served to all who would enter that here was a protected and exclusive preserve for its owner occupiers. 

Time traipse several hundred years and cross the Atlantic to America’s propertied. To find remarkable similarities in all but the castle or battlements thing. As Maggie Smith verbally duelled with Shirley Maclane so ably - though ‘outgunned’ on this particular point - “Americans” she complained to Edith, “they always get our underbelly!” 

To wit, tradition stood for little at all once property ownership conferred rights to self-defence and exclusive family life. Which had become the model most sought under a written Constitution in the United States of America.

And so on into business: property whether a railway or bank held lawful right to defend. Under bandit attack a call to private posse or public was the way of things.

We are, of course, in the physical realm, where forces were perceived and resources pitted to equal and opposite engagement. To uphold one’s property. 

But what then of wealth in the human mind and intellectual property? Why, nothing much, is the honest answer. American owners of intellectual property conferred upon themselves the right to self-defense.

Which has become a major and enduring problem once vast corporate wealth came upon and absorbed not Lady Grantham’s traditional values so much as Americans’ very own model most sought.

Here’s How..

Patents, were designed, as we have heard in recent days (President Obama’s initiative vs patent trolls (see below) are what lawfully confer on their owners protection against duplicity and in the pharmaceutical industry an exclusive period of time - say 15 years - whereby a patented product can be marketed so as to recover R&D costs and secure market share. From which investors make commercial return on their investment.

Through the decades1950-1980 many pharmaceuticals came from R&D, thence via the FDA(Federal Drugs Administration) back out to branding and US markets. Further, with multinational companies, such patented US brands went into overseas markets. Driven we could reasonably conclude by the fact of opportunity to medicate more widely, earn sizeable revenues and grow greater profits amounting to well satisfied/rewarded executives and boards.

Such was this opportunity that multis were legion and all with like attitudes of there being enough global opportunity to go around. Branded made the best returns. And so, wherever possible, US firms would ‘do what it takes’ to secure those brands. Not least, by longer patent lives(aka extended exclusivity periods.. 20 years instead of an earlier agreed 15. 1990s exec analysis might go something like: 5 more years and expanding means a cool billion so what’s $50M on lawyers ta do our thinking.

The picture I’ve drawn here is deliberate so as to have you recognise the old saw that when money is talking intellect can go out the window. And I make this pointedly in the knowledge of a US President fronting for his republican constituency and their Bah Humbug! dismissals of expensive lawyers. Pardon my poet-try but the following has sprung to mind:—

Tricky Dicky’ was for them long gone; 
firm execs do the done! from now on.

Legal dexterity on behalf Big Pharma’s patents amounted to defense, period. Devil’s advocate for a moment I’d say specialist lawyers were deemed necessary by weak-minded employers. So who among them might pass up good opportunities to leverage fees for so simple and justifiable a practice. In the land of the free there was free market mania. Defense was staked in the grounds of growth. 

Blockbuster drugs.

Holler was in boardrooms: Hey, the world is going global. We—yeah—wees making it global. My firm is global, it aint multinational anymore. We need more. Y’guys gotta think billions..

Nor am I lite here. Fact: According to Matthew Herper@Forbes(2012) the top-selling medicine ever earned (US)$12Bn in a single year. Anyone care to name this was Pfizer's Lipitor. The blockbuster drug, which is used to lower cholesterol levels, was first introduced to the market in 1997 and had a strong run of exclusivity until its patent expired in late 2011. One source puts its gross overall sales prior to it falling off the ‘patent cliff’ at $123bn. 

But let us be careful and conservative in a calculable and sensible linear annual earnings accumulation. 1997-2000(4yrs) it makes (US)$2bn. Each year thereafter to 2009 it adds a further $1bn to the total for 8 years [= 12 in its patent calendar]. Gross to date: $54bn. The next couple of years it ticks over at the same rate(#10bn/yr) then in the final exclusive it kicks to $12bn. Grand total $86bn.

Now I set the first figure ($2bn) because experience tells me that every marketing effort is made early to cover R&D costs for a particular drug. This can take time and four years is a reasonable expectation. As the $ figure at or prior to 1997 is also reasonable.

I should point out that it is an add-on creative accounting - for instance including company acquisition costs which really are more market-rooted than R&D expenditures, and a most dubious practice of including capital costs(aka other utility or use) in accounting R&D costs. Of course when such things and loss-generating incompetances are low-balled into this single category then this excuse of excuses for why pharmaceuticals cost so much can appear very large indeed. My suggestion is that buyers be more than aware and have the blighters declare! Everything. Before you part with a nickel.

In terms of market returns a good rule of thumb is that US sales rank 50 percent of total global sales. Examine this specific and we know from US sales data ONLY how SEVEN drugs came in with $1bn in quarterly sales. US citizens are solely accounting here for what corporates term an implicit willingness to pay high prices for their prescription drugs.

Should this be the driver of overseas pharmaceutical drug pricing then I suggest it be considered a Model Least Sought

Bear in mind, please do, that in the USA its patent drug cliff is one of the driver's to greater incomes - hopefully to make up the shortfalls generics usage has generated. Another, of course, is need to climb out of recessionary status and economic conditions.

But these matters are well canvassed there if not elsewhere. Along with alternative, so-called ORPHAN drugs development for orphan(rare = < 200,000 US patients with a diagnosed and prescribable condition) which are rendering a US cachet to patient populations around the globe.

Next I'd like to cover some aspects of these and other matters before moving into a closer scrutiny of a particular orphan drug product.

* Patent trolls — Hattip radionz’s webmaster via their Worldwatch of last Sunday morning, I understand that American Life has an excellent 2-parter on this topic.

Rare Afflictions: Medicine or Markets - 02

This post subtitles: 2 Steps, 1 Leap

Hopkins, I’d call him Hoppy, was an old-fashioned chemist. Which was to say that his all seasons brown suit, check shirt and braces belonged more in the plant offices of industrial chemical processing than sharp new organic and biological laboratories. But Guinness liked him and his respectable cut held more for their North London venture’s management than any of the new crowd. From PM Wilson’s scientific future flock. 

A quantitative professional, measure to his mind superior to mere chemical presence. And the reason he sat behind his desk in a corner of the second floor premise. North of Western Avenue and Walls sausages where, gossip held, a future Maggie Thatcher had commenced minion career in an experimental ice-cream shack. 

In his room without a view Hoppy acquired a crafty skill. Rather than admit ignorance he would nod. I was to term it the not-nod. Not for him an understanding of novel gas chromatography to separate small volumes of fats. Not for him my nouveau recollections of titrating hydrofluoric acid in I.C.I. fume cupboards.  Hairs rose on the back of necks at such exploits, but if they did with Hoppy it was lost to the nod. At the job interview so fascinated was I with it that I missed the look in his eyes at relating my ambition to make better iron absorption possible for anaemic patients.

Thusly I was surprised to receive an interim job offer several weeks later. Just back from my first OE and pretty broke I took it. To realise how his ignorance was my gain in having a free hand to R&D inorganic iron onto saccharide(sugar) transfer complexes. The one haematinics option of its time and place to gain a good look. And soon resulting in healthier and bigger pigs.

Hoppy smiled more, doubtless thrilled with his office’s well-taken praise from firm overseers and management. Pork, bacon and foods market revenues were well worth having in addition to their excellent beverage as Europe recovered and its populations began to bulge. Besides which patented properties accrued for their holders both across the Atlantic and later the world. Big business indeed, as Virginia’s joy -  - in recent days has shown. 

Smiling, however, does not make the vet-lit and the past was to resettle on Hoppy as soon as I’d left to pursue med-lit mentions for myself. Plus salting away any spare cash I could muster at evening dinner tables - eat your heart Abel* - into sure things. 

Yet to Hoppy I am impelled to attribute a very solid lesson regarding parental administration of chemical substances. In short: WHAT GOES IN HAS GOT TO COME OUT. And no, not as a bloody rash at the site of injection! As he put it so very well.

* Protagonist in the novel Kane & Abel.

Step UP

In relating that small step back I believe readers are more able to register several aspects of last week’s post ( qv below ). And in returning to chloramphenicol for what it was capable of inside the body of a patient for whom aplastic anaemia was never intended.

First a moment to clear up what this term means. Collins dictionary has the literal(ex Latin) prefix meaning - without plasticity. Unhelpful.

Better is Miller Keanes’s Medical dictionary— aplastic [a-plas´tik] - pertaining to or characterized by aplasia( = bone marrow failure); having no tendency to develop into new tissue…[ note: with my underlining ] This may be due to:—
  •  chemical factors such as drugs
  • physical factors such as radiation,
  • infection by a virus, or 
  • idiopathic congenital defects of the stem cells of the bone marrow
It is characterized by a reduction or depletion of hemopoietic(blood) precursor cells with decreased production of white blood cells (leukocytes), red blood cells(erythrocytes), and platelets.

Added to which - and relating to upcoming content on the treatment for PNH mentioned earlier - I’d like to widen context of recorded findings in respect of contemporary doctors checking the immune system for proteins called antibodies. They say, “Antibodies in the immune system that attack your bone marrow cells may cause aplastic anemia.”  

What was it about this inexpensive, rapidly absorbed and distributed bacteriostatic (inhibits bacteria as distinct from bactericides which kill) antibiotic whose 250mg capsules were easily taken by mouth..?

Relative that is to aplastic anaemia's(AA) rarity. Back in the day, 1 case in 50K, was held to be the U.K. incidence. That is 1 case in 50K chloramphenicol courses of treatment. Hardly noticeable you might conclude correctly. In fact twas some 3 years from its introduction before serious blood disorders were reported. Recipe for rarity was large city populations, widespread prescribing and broad spectrum application. Thence to children, in whom a greater and closer parental scrutiny was I daresay taken.

But this rarity in reality was part of the problem. Witness Gairdner’s case (BMJ, 1954, 2, 1107). “A girl of 4 years” presenting “on attack of bronchitis and asthma for which she received 1gm daily for 4 days. Six months later she developed a sore throat, treated with a further course of 1gm daily for 4 days. Three days after completing this course a purpuric(blood) rash appeared and in spite of blood transfusion she died two weeks later”.  AA was found at necropsy.

Suggests, does it not, how the first course whilst presumably working also found and ‘occupied’ a vulnerability in the patient’s body. Made worse and much more obviously SIX MONTHS LATER!

Bringing us back to the question of what was going on inside the patient?

Answers came after a fairly brutal trial in premature babies. At the time routine chemoprophylaxis(antibiotic cover) was prevalent. [ Recall if you will the 1920s period Downton Abbey drama whereby watchers saw the medical debate around Lady Sybil’s delivery. Caesarean, they argued, could kill both mother and child—we have no treatments to use—].

3 decades on the trial allocated 4 treatment groups of approx. 30 babies each:—
  1.  no drug, 
  2. chloramphenicol(C), 
  3. penicillin(P) + streptomycin(S), and 
  4. P + S + C. 
Resulting in: First and third groups ~20 percent died. Chloramphenicol groups, 60-70 percent died.

Cause of death was circulatory collapse with high chloramphenicol plasma concentrations due to a failure of the liver to conjugate, and kidney to excrete, the drug.

What WAS GOING IN WAS STAYING IN. Not changing, as with older and competant organ development, but damaging by its continued presence.

Yes, biochemical investigation in the fate of drugs in the IMMATURE can predict safe dosage schedules, but point is made that UNCONTROLLED chemoprophylaxis with its loss of life is not to be tolerated by clinicians. 

Indeed uncontrolled anywhere, anytime and over time is to be avoided wherever possible.

Leap.


Fifty years + later I was to see an aging lady with one very swollen and angry toe. No, she recalled to her doctor’s question, she had not “banged” it in the garden. Yet ohh.. hadn’t she stubbed it on a bedpost. He stooped, leaned, looked, felt then washed his hands. Talking all the while to put her mind at ease. 

“Classic case.. you ask me.. You are asking me aren’t you.. thought so.. and for classic cases - I’d take a photo if I hadn’t seen so many like it in my time. Yes, you’re bigger than many but not so big that my classic treatment with its life of efficacy wont polish it orf in next to no time… Now quiet please while I get this newfangled computer to print out your very own prescription..”

In thrall she pulled a large stocking back over her foot and took the print out with her. As I looked at the screen in some astonishment.

“Well, said he to me with a grin, “some of your questions I can’t answer—too special for a GP like me, but I know gout when I see it and… and I do know how to treat it. Stubbed it, came up real fast right.. I say Staph aureus.. and that’s how you deal with it. Do you know the people who make this antiobiotic held it back for years.. and years. Keep it in your bag, doc, their rep would tell me, you never know when.. blah blah. What’s funny, whaddya smiling like that for..?”

“Life of efficacy,” I said. And he grinned again. Then, not wishing to explain himself, said, “ This time tomorrow she’ll be right. But I must get nurse to call and make sure she finishes the course.”

And she was, and she did. Erythromycin had made the leap.

Been a While..

SINCE I posted here.

But I do need say something - LOBBY - and other spots are not appropriate.

Soon I intend making a submission IMPORTANT for why a government agency, which has been reported to reject an efficacious biopharmaceutical, would do so. And for equally significant reasons to its very high treatment costs.

Concerns to balance pertinent matters in reaching my conclusion will be recalled and recounted.

Today I'd like begin with the first of those. Recalling a past event will most certainly state where I am coming from. Though I hasten to add that readers seeking only what they want to hear would be wise not to presume anything more than what is presented.

Let's entitle this series of posts RARE AFFLICTIONS: MEDICINE or MARKETS?
