Targeted failure of the week. Post No 25. Masitinib.

A new week - a new failure of targeted medicine. This time we have another targeted candidate - Tyrosine kinase inhibitor Masitinib:
AB Science S.A. (Euronext:AB) reported late Tuesday that masitinib plus Gemzar gemcitabine missed the primary endpoint of median overall survival (OS) vs. placebo plus Gemzar in a Phase III trial to treat pancreatic cancer (7.7 vs. 7 months, p=0.74).
Well, game with masitinib over? Never! AB Science does not give up! The company desperately tries to find something positive in the situation:
In a subgroup of patients with an undisclosed genetic biomarker that the company said is indicative of aggressive disease progression, masitinib plus Gemzar significantly improved median OS vs. placebo plus Gemzar (11 vs. 5 months, p=0.000038). In a second subgroup of patients with a pain intensity level above an undisclosed threshold at baseline, masitinib plus Gemzar also significantly improved median OS vs. placebo plus Gemzar (8.1 vs. 5.4 months, p=0.01). AB Science could not be reached for details.
And I suspect that the key words here: “AB Science could not be reached for details”.
Well, who fails next?

Targeted medicines against cancer fail. Even cancer specilists are convinced!

Everybody who follows my blog already knows my position to targeted approach, personalized medicine and R&D strategies of Big Pharma. And today we have an article from The Guardian as an fine illustration of my point of view.

Progress against cancer is stalling, with the latest targeted cancer drugs failing to live up to expectations and priced so high that treatment is becoming unaffordable even in rich countries, according to experts at a meeting of nearly 100 eminent cancer specialists from around the world.

Only a few years ago, many cancer experts thought the arrival of targeted medicines, designed to attack the genetic makeup of the tumour, would make dramatic inroads into cancer deaths. That has not happened. Instead, these therapies have only bought a few extra months of life. If the question was whether the world was winning the war on cancer, said Douglas Hanahan of the Swiss Institute for Experimental Cancer Research, who outlined the latest state of drug research, "in general, for most forms of human cancer, the answer is clearly no".

The excitement generated by targeted drugs, which interfere with specific molecules involved in tumour growth and suppression, has been short-lived.

Doctors reported apparently miraculous results from the use of the BRAF-inhibitor vemurafenib in advanced malignant melanoma, a usually fatal form of skin cancer. Within two weeks, the tumours had melted away.

"But six months later, [the cancer] is back with a vengeance," he said.

Other drugs working in a similar way – including erlotinib (Tarceva) for a form of lung cancer, bevacizumab (Avastin) for breast, colorectal and other cancers, and sunitinib (Sutent) for renal cell carcinoma and gastrointestinal sarcoma – have also not done so well, said Hanahan. Resistance to the drugs builds up, sometimes very quickly. "All came on line with great expectations. The reality check is they are all working in the important first step, but we have a long way to go in terms of winning the war."

The future is probably using these drugs together or in combination with other, older types of drugs, but the price is likely to be prohibitive.

A year's treatment with vemurafenib alone would cost £91,000. Even though the manufacturer, Roche, has offered an undisclosed discount to the Department of Health, the National Institute for Health and Clinical Excellence said in June it was too much for the NHS to pay. No health service will be able to afford to put a patient on two or three such drugs at the same time.

Well, once again, can you see a conflict of interests here? Big Pharma is out there to make profits – not to cure cancer. The best scenario for Big Pharma is a launching of novel extremely expensive (and profitable for Big Pharma) medicines for treatment of cancer which is only a little bit more efficient that former medicines – this approach generates profits without decreasing the market size. Smart? Definitively! Sad? Yes, but true...

Why winners fail in clinical trials

I constantly mention failures in clinical trials. I have the impression that Big Pharma needs to brag about all of potential candidates in pipe-lines – it is a part of the game due to PR-activity increases values and capitalization of Big Pharma. And here we can see that later on the candidates fail on clinical trials – as it should be very simply expected:
A new study that has examined the results of thousands of clinical trials has determined that 90% of the early winners failed to continue to produce the same clinical effect in later studies. A whopping 98% of the follow-on studies that did see a big effect failed to continue to wow investigators in subsequent trials.
So why is disappointment the ultimate rule for drug developers? Dr. John Ioannidis at Stanford says the big reason is trial size. If you study a drug in a small trial, random positive responses tend distort the results, skewing the data in a way that wows developers.
"I think some healthy skepticism and a conservative approach may be warranted if only a single study is available--even more so if that study is small and/or had obvious problems and biases," Ioannidis tells HealthDay. "Most of the time, waiting for some better, larger, more definitive evidence is a good idea. No need to rush."
Well, I completely disagree that the only reason of the failures is a size of the trials – the failures is a part of the game, they are the trade-off of a PR-activity which is designed to provide some kind of evidence THAT Big Pharma has capacity and potential to launch novel promising drugs. And I have written earlier that Big Pharma basically is not very interesting in innovations.

Big Pharma as ... a bunch of lemmings?

I have proven that Big Pharma is not interested in innovations and R&D working process are very inefficient. Here are the same suggestions from Wall Street analyst. Very interesting reading:

Wall Street analyst Raghuram Selveraju likens today’s drug-development landscape to the changes seen in men’s professional tennis between the era of Bjorn Borg and John McEnroe and the completely different game played today by the likes of Roger Federer and Novak Djokovic. In today’s tennis, the ball is hit much harder and yet at the same time there is almost no margin for error. Likewise, he says, in drug-development today, companies must navigate tougher regulatory requirements for both efficacy and safety.
 
“The margin for error is razor thin and if you miss it, you lose big time. Aspirin would not get approved at the FDA in today’s atmosphere,” said Selveraju, managing director and head of health care equity research at Aegis Capital.
That desperation leads to the repetition of familiar mistakes which derive from the predictable thinking of too many business development executives at big pharma, Selveraju opined. First, when looking for licensing opportunities, pharmas very often seek out their comfort zone – a potential product for which they can deploy an existing sales force or promote to doctors they already know and communicate with. Also, to be confident in an experimental drug’s preclinical and clinical data, pharmas often want to go into areas where their competitors also have a compound as well as into validated targets.
“Basically, they’re a bunch of lemmings,” Selveraju said. “As soon as a target becomes hot, they all have to have a molecule in that space, hitting that target. We’ve seen that multiple times: with the DPP4 inhibitors, the statins, the S1P inhibitors now, the nucs in hepatitis C.” Bristol paid $2.5 billion for Inhibitex and its nuc in part because months before Gilead had paid $11 billion for Pharmasset and its promising, mid-stage nuc.
And it’s just not that easy, at least not today. The low-hanging fruit largely has been picked – there is no preponderance of easy-to-hit, druggable targets available to business development groups, Selveraju explained. Faced instead with a panoply of more difficult to address therapeutic indications, business development officials often must make decisions based on incomplete data and at the same time pay out huge premiums because of the competition with other companies to find “the next big thing.”
“Big pharma chases targets and it chases indications,” he said. “That’s what leads to these deals with outsized valuations and to the disappointingly high failure rate. If big pharma were to take a more pragmatic approach, a more rational approach, then we might not be seeing so many of these failures and we’d certainly be seeing more judiciously priced deals.”
What then is Selveraju’s prescription for better business development practices? It might disappoint those who want pharma to be in the vanguard of innovation. He recommends incremental innovation – using FDA’s 505b2 pathway to develop products with already defined efficacy and safety – as well as biosimilars and re-purposing. Pharma also should focus on niche and specialty indications, and largely eliminate primary care products and the large commercial operations that come with them.
That may be an unappealing remedy for many, but given the spate of recent blow-ups in pharma/biotech deal-making, something needs to change. Right?
Yes, basically it is right. I think and hope that R&D activity has to be changed. I strongly believe in a paradigm shift. And only states and Big Pharma have the necessary resources for that. Not all Big Pharma corporations will survive the coming dramatic changes. But the winner takes it all...

Novo Nordisk is in danger!


Very terrible news for Novo Nordisk:

Novo Nordisk A/S (NOVOB), the world’s biggest insulin maker, fell the most in 14 months after U.S. regulators disclosed that a scheduled advisory panel on the diabetes treatment Tresiba will focus on cardiovascular risks.


Novo needs the medicine, a long-acting insulin also known as degludec, to wrest market share from Paris-based Sanofi (SAN)’s best-selling Lantus, which generated $5.5 billion in revenue last year, according to data compiled by Bloomberg. Novo said in September that nothing gave it concern about Tresiba’s safety.


Regulators have to be more careful: Novo realy needs this drug, really needs the multi-billion revenue. I will pay very much attention to the situation...

Regarding efficiency of chemotherapy

From here:
At least two thirds of people with advanced cancer in a new survey believed the chemotherapy they're receiving might cure them, even though the treatment is only being given to buy some time or make them comfortable.
When lung cancer or colorectal cancer has spread, chemotherapy may extend survival for weeks or months at a cost of some substantial side effects.
This is very sad but true. The reality is harsh. No cures, no magic bullets.

And what about Big Pharma and ethics?

I have written in a previous post that Goldman’s business is not of moral but what about Big Pharma? Let’s be honest (not naïve at least) and state that Big Pharma as basically other type of business is out there just with one major purpose: making money. Big Pharma just wants big bucks – nothing more. Big Pharma is not out there to provide customers with safe products, and here is a fresh example concerning Roche:  
Three months after the European Medicines Agency found that Roche failed to report tens of thousands of adverse events in connection with its various drugs, including 15,161 patient deaths, the agency is now initiating what its calls an infringement procedure at the request of the European Commission
Roche identified some 80,000 reports for medicines marketed in the US that had been collected through its patient support program, but these had not been evaluated to determine whether they should have been reported as suspected adverse reactions to EU authorities
There were also questions about 23,000 adverse events related to evaluating and reporting to regulators and 600 pertaining to clinical trials.
Well, it is not personal to Roche – I am convinced that the same problems will be found in other companies if we just dig a little bit deeper. And we have a conflict of interest: why Big Pharma should provide the market with safe drugs? By curing people Big Pharma reduces the market and the amount of customers. And Big Pharma is not so stupid to do this big mistake. It is really sad but definitively true… For more details see here.

GBI report: Drug Delivery

Drug delivery technologies provide commercial opportunities for pharmaceutical companies by improving the chances of success for a drug development project. They enable the formulation of a promising molecule that might have poor solubility or require selective delivery to a particular tissue, such as the brain. Similarly, drug delivery technologies may enable companies to differentiate products within crowded therapeutic areas, facilitate life cycle management for existing drugs, and reposition existing drugs – proprietary or generic – in new indications where the needs of the patient population are different or, again, where more targeted delivery is required. Products that are reformulated with novel drug delivery systems do not meet the traditional criteria for innovative products – in other words, products that include new active moieties. Nevertheless, GBI Research’s analysis shows that the commercial success of existing products that rely on innovative drug delivery technologies is clear, and these products make significant positive changes for patients.
Well, it can be interesting...

Diet and weight loss are not enough… Pereslegin wins!

Very terrible news! (For modern and post-modern society, not for pre-modern …):
A large federal study of whether diet and weight loss can prevent heart attacks and strokes in overweight and obese people with Type 2 diabetes has ended two years ahead of schedule because the intensive program did not help.
“I was surprised,” said Rena Wing, the study’s chairwoman and a professor of psychiatry and human behavior at Brown University’s medical school.
Like many, she had assumed diet and exercise would help, in part because short-term studies had found that those strategies lowered blood sugar levels, blood pressure and cholesterol levels.
No way! How it could be possible? Well, it was somehow predicted by Pereslegin: fitness revolution has completely failed to provide the second epidemiologic jump (transition)(see video somewhere from 1:07:00), and, according to his teaching, why diet and weight loss be helpful against diabetes? Bravo, Pereslegin!

Drug repositioning. When development of novel drugs fails?

Very interesting trend in Big Pharma strategy: Drug repositioning:
Drug repositioning or repurposing is a strategy by which new or additional value is generated from a drug by targeting diseases other than those for which it was originally intended. Repositioning of launched or failed drugs has opened up a new source of revenue to large, medium and small Pharma companies as well as attracting venture capital funding, and is expected to generate up to $20 billion in annual sales in 2012. Drug repositioning is not a new strategy and there are a number of examples of drugs that have been successfully repositioned such as gemcitabine and sildenafil (Table 1). These and many other examples have addressed an unmet medical need in selected patient groups as well as creating substantial value for the company that repositioned the drug. One of the most interesting and extreme examples of repositioning is thalidomide, which was launched in 1957 as a sedative but was later found to be responsible for severe birth defects in children when used by pregnant women to alleviate morning sickness. After additional scientific inquiry the drug has since been shown to be safe in selected patient groups and to be very effective in pain relief in leprosy and Kaposi’s sarcoma, generating $528M in revenue per year.
Well, if this strategy helps to treat diseases and help people – just fine! But this trend and approach is a very nice illustration that new drug development (which is based on predominantly on “targeted” approach) is very inefficient.

Targeted failure of the week. Post No 24. Bardoxolone

Well, it’s a little bit funny but we have failures of targeted medicine literally EVERY DAY! Today we have bardoxolone which is an orally-available first-in-class synthetic triterpenoid. It is an inducer of the Nrf2 pathway, which can suppress oxidative stress and inflammation – i.e. “targeted”-paradigm drug. And Abbott suffers pretty much economically:
Just three months before its planned split into two companies, Abbott Laboratories is suffering a significant setback after a Phase III trial for a chronic kidney disease treatment was ended due to an excessive number of deaths and serious adverse events in patients. The actual number of deaths was not specified by Reata Pharmaceuticals, which is developing the drug.
Two years ago, Abbott paid $450 million to Reata – and agreed to another $350 million in milestone payments – for the bardoxolone medication . Some Wall Street analysts believed could become a $1 billion or more blockbuster seller and fuel the growth of the research-based pharma operation to be spun off this coming January.
Now, investors are concerned the spin off, to be called AbbVie, will have to rely too heavily on sales of Humira, which generates $8 billion in annual sales. Following the news, Abbott stock fell nearly 5 percent on excessively heady trading volume. Just yesterday, Abbott disclosed that AbbVie’s annual tax rate will be higher than expected, which will hurt its earnings.
The decision to the end trial, which was called Beacone, was recommended by an Independent Data Monitoring committee. The drug was being tested in patients with stage 4 chronic kidney disease and type 2 diabetes. Reata added that regulators have been notified, but did not provide any details on side effects
Well. It should be expected. I wonder: how many risk managers work for Abbott? And what is the scale of their bonuses?

Targeted failure of the week. Post No 23. Inlyta


Another day – another failure of a targeted drug! This time fails Inlyta (Axitinib or AG013736) which is a targeted molecule (tyrosine kinase inhibitor) developed by Pfizer.

Pfizer Inc said its kidney cancer drug did not meet the main goal of showing a statistically significant improvement in survival in a late-stage trial without the cancer getting worse.

The trial was testing the drug Inlyta in patients who have received no prior treatments and compared its effects with another kidney cancer drug, sorafenib. Inlyta is already approved to treat kidney cancer that has not responded to prior therapy.

Well, who will fail next?

Another magic cure from cancer. Post No 23.

This time… well… rhinoceros horns… I am serious!
A record number of African rhinos were illegally killed in South Africa this year, driven by the use of their horns in Chinese medicine and a spreading belief in Southeast Asia, unfounded in science, that they may cure cancer.
The street value of rhinoceros horns has soared to about $65,000 a kilogramme, making it more expensive than gold.
South Africa, home to more than 20,000 rhinos, or about 90 percent of all the rhinos in Africa, lost 455 rhinos to poachers, as of Tuesday, to eclipse the 448 killed in all of 2011, the environment ministry said in a statement.
Around 15 animals a year were lost a decade ago, showing the impact of rising demand from Asia.
I know that people are very intelligent. And the following information just means only one thing: the modern scientific anticancer medicine is not much better than traditional rhinoceros horns. Sad but true!

India as the ultimate enemy of Big Pharma

It looks like India is the only opposition to Big Pharma. The state has its own view on IP and licensing issues (I have written about the situation here and here). And India just continues to be aggressive with IP questions – no doubts about it:
Medicines in India may not be sold under brand names in the near future. In its biggest move to push generic drugs and do away with brand names, the Union health ministry has ordered states to stop issuing licence for the manufacture or sale of drugs on the basis of their brand name.
All pharmaceutical firms applying for licence to market or manufacture fixed dose combination (FDC) drugs will have to submit their generic name and not as brands with immediate effect. The move will substantially reduce medicines' prices.
For example, Crocin will cease to exist, and it will be marketed and sold as paracetamol.
Drug controller general of India Dr G N Singh said, "We want to gradually move towards a future where we will not issue any brand or trade names. We are going all out to push generic drugs solely for the benefit of the public."
He added, "We have sent the order to all state health secretaries asking them to instruct their drug licencing issuing authority to issue licences only on generic names and not on branded or trade names, which is the usual practice now. A branded drug can be 10 times more expensive than a generic variant."
The parliamentary standing committee in its recent scathing report had also expressed strong objection to the practice of issuing licences on brand names.
I think that Big Pharma has to act in some way – the situation is very serious! Just think if other countries will apply the same policy? Big Pharma: do something, it is your turn!

Targeted failure of the week. Post No 22. mAb fails again: Girentuximab

Yes, a new mAbs, a new failure!
Wilex AG (Xetra:WL6) fell EUR 2.40 (62%) to EUR 1.50 on Tuesday after Rencarex girentuximab missed the primary endpoint of improving median disease-free survival (DFS) vs. placebo in the Phase III ARISER trial to treat clear cell renal cell carcinoma (RCC). ARISER was evaluating once-weekly Rencarex for 24 weeks following complete or partial surgical removal of the affected kidney in patients with no detectable metastases. Rencarex is a chimeric mAb against carbonic anhydrase IX (CAIX).
Well, let’s see who will fail next…

Another cure from the cancer. Post No 22.

Well, it looks like the magic cure against cancer was found 100 years ago!

Music of the week. Pulp fiction...

How much mAbs should cost? And should they be used in the first place? Case study: Zaltrap

It looks like a revolt in pharma branch:

AT Memorial Sloan-Kettering Cancer Center, we recently made a decision that should have been a no-brainer: we are not going to give a phenomenally expensive new cancer drug to our patients.
 

The reasons are simple: The drug, Zaltrap, has proved to be no better than a similar medicine we already have for advanced colorectal cancer, while its price — at $11,063 on average for a month of treatment — is more than twice as high.

 In most industries something that offers no advantage over its competitors and yet sells for twice the price would never even get on the market. But that is not how things work for drugs. The Food and Drug Administration approves drugs if they are shown to be “safe and effective.” It does not consider what the relative costs might be once the new medicine is marketed.
….
This is particularly the case with cancer, where the cost of drugs, and of care over all, has risen precipitously. The typical new cancer drug coming on the market a decade ago cost about $4,500 per month (in 2012 dollars); since 2010 the median price has been around $10,000. Two of the new cancer drugs cost more than $35,000 each per month of treatment.


The burden of this cost is borne, increasingly, by patients themselves — and the effects can be devastating. In 2006, one-quarter of cancer patients reported that they had used up all or most of their savings paying for care; a study last year reported that 2 percent of cancer patients were driven into bankruptcy by their illness and its treatment. One in 10 cancer patients now reports spending more than $18,000 out of pocket on care.

Which brings us back to our decision on Zaltrap. In patients with advancing, metastatic colorectal cancer, the new drug, approved by the F.D.A. in August and jointly marketed by Sanofi and Regeneron, offers the same survival benefit as Genentech’s Avastin, which works through a similar molecular mechanism. When compared with the standard chemotherapy regimen alone, adding either medicine has been shown to prolong patient lives by a median of 1.4 months. Major clinical practice guidelines, like those from the National Comprehensive Cancer Network, agree that Zaltrap is no better than Avastin in this setting. (Full disclosure: Two of us, Dr. Bach and Dr. Saltz, have been paid consulting fees by Genentech.)

But Avastin costs roughly $5,000 a month: very expensive in its own right, yet less than half of Zaltrap’s price tag. And while the side effects in both drugs are roughly equal, doses of Avastin generally take less time to administer than those of Zaltrap, which makes Avastin more convenient for patients.

Consider that colorectal cancer is typically diagnosed in older individuals and the cost issue becomes starker still. Many patients are on Medicare and living on fixed incomes. And because Medicare requires patients to co-pay for cancer drugs, 20 percent of the cost of drugs like Zaltrap and Avastin is passed on — absorbed either by supplemental insurance or by the patients themselves.

The current level of spending on health care, estimated to be $2.8 trillion this year, is already too high. The growth rate in health spending is unsustainable.


Of course, we know our decision about Zaltrap will not meaningfully address these larger problems. Projected United States sales of Zaltrap in 2013 are less than $150 million, or 0.005 percent of all dollars spent on health care. Our use would account for a very small percentage of even that number.

The key statement here is “we are not going to give a phenomenally expensive new cancer drug to our patients”. Period! The question: do these doctors realize that Big Pharma definitively has another opinion?

Quote of the day. They just can be marketed...


"Antipsychotics and antidepressants have been some of the most profitable agents for companies over the last two decades," said Dr. Thomas Insel, director of the U.S. National Institute of Mental Health and one of the authors.
"But that doesn't mean they're effective. What it means is that they sell and they can be marketed."

Not bad, right? And another statement (just think about the ineffectiveness of targeted approach, ha-ha):

The drugs are descended from serendipitous discoveries such as the mood stabilizing effects of lithium in 1949, said Steven Hyman of Harvard University in Cambridge, Mass., and the author of the second paper.
"The central problem is clear: Neither vast unmet medical need, nor large and growing markets, nor concerted sales campaigns that attempt to recast 'me-too drugs' as innovative can illuminate a path across very difficult scientific terrain," Hyman wrote.
