Aging, inflammation, cancer, and cellular senescence are all intimately interconnected. Deciphering the nature of each thread is a tremendous task, but must be done if preventative and geriatric medicine ever hope to advance. A one-dimensional analysis simply will not suffice. Without a strong understanding of the genetic, epigenetic, intercellular, and intracellular factors at work, only an incomplete picture can be formed. However, even with an incomplete picture, useful therapeutics can be and are being developed. One face is cancer, in reality a number of diseases characterized by uncontrolled cell division. The other is degradation, which causes a slue of degenerative disorders stemming from deterioration in regenerative capacity.

Now there is a new focus on making geroprotectors, which are a diverse and growing family of compounds that assist in preventing and reversing the unwanted side effects of aging. Senolytics, a subset of this broad group, accomplish this feat by encouraging the removal of decrepit cells. A few examples include dasatinib, quercetin, and ABT263. Although more research must be done, there are a precious handful of studies accessible to anyone with the inclination to scroll to the works cited section of this article. Those within the life-extension community and a few enlightened souls outside of it already know this, but it bears repeating: in the developed world all major diseases are the direct result of the aging process. Accepting this rather simple premise, and you really ought to, should stoke your enthusiasm for the first generation of anti-aging elixirs and treatments. Before diving into the details of these promising new pharmaceuticals, nanotechnology, and gene therapies we must ask what is cellular senescence? What causes it? What purpose does it serve?

Depending on the context in which it is operating, a single gene can have positive or negative effects on an organism’s phenotype. Often the gene is exerting both desirable and undesirable influences at the same time. This is called antagonistic pleiotropy. For example, high levels of testosterone can confer several reproductive advantages in youth, but in elderly men can increase their likelihood of developing prostate cancer. Cellular senescence is a protective measure; it is a response to damage that could potentially turn a healthy cell into a malignant one. Understandably, this becomes considerably more complex when one is examining multiple genes and multiple pathways. Identifying all of the players involved is difficult enough. Conboy’s famous parabiosis experiment, where a young mouse’s system revived an old ones, shows that alterations in the microenviornment, in this case identified and unidentified factors in the blood of young mice, can be very beneficial to their elders. Conversely, there is a solid body of evidence that shows senescent cells can have a bad influence on their neighbors. How can something similar be achieved in humans without having to surgically attach a senior citizen to a college freshman?

By halting its own division, a senescent cell removes itself as an immediate tumorigenic threat. Yet the accumulation of nondividing cells is implicated in a host of pathologies, including, somewhat paradoxically, cancer, which, as any life actuary’s mortality table will show, is yet another bedfellow of the second half of life. The single greatest risk factor for developing cancer is age. The Hayflick Limit is well known to most people who have ever excitedly watched the drama of a freshly inoculated petri dish. After exhausting their telomeres, cells stop dividing. Hayflick et al. astutely noted that “the [cessation of cell growth] in culture may be related to senescence in vivo.” Although cellular senescnece is considered irreversible, a select few cells can resume normal growth after the inactivation of the p53 tumor suppressor. The removal of p16, a related gene, resulted in the elimination of the progeroid phenotype in mice. There are several important p’s at play here, but two are enough for now.

Our bodies are bombarded by insults to their resilient but woefully vincible microscopic machinery. Oxidative stress, DNA damage, telomeric dysfunction, carcinogens, assorted mutations from assorted causes, necessary or unnecessary immunological responses to internal or external factors, all take their toll. In response cells may repair themselves, they may activate an apoptotic pathway to kill themselves, or just stop proliferating. After suffering these slings and arrows, p53 is activated. Not surprisingly, mice carrying a hyperactive form of p53 display high levels of cellular senescence. To quote Campisi, abnormalities in p53 and p15 are found in “most, if not all, cancers.” Knocking p53 out altogether produced mice unusually free of tumors, but those mice find themselves prematurely past their prime. There is a clear trade-off here.

In a later experiment Garcia-Cao modified p53 to only express itself when activated. The mice exhibited normal longevity as well as an“unusual resistance to cancer.” Though it may seem so, these two cellular states are most certainly not opposing fates. As it is with oxidative stress and nutrient sensing, two other components of senescence or lack thereof, the goal is not to increase or decrease one side disproportionately, but to find the correct balance between many competing entities to maintain healthy homeostasis. As mentioned earlier, telomeres play an important role in geroconversion, the transformation of quiescent cells into senescent ones. Meta-analyses have shown a strong relationship between short telomeres and mortality risk, especially in younger people. Although cancer cells activate telomerase to overcome the Hayflick Limit, it is not entirely certain if the activation of telomerase is oncogenic.

SASP (senescence-associated secretory phenotype) is associated with chronic inflammation, which itself is implicated in a growing list of common infirmities. Many SASP factors are known to stimulate phenotypes similar to those displayed by aggressive cancer cells. The simultaneous injection of senescent fibroblasts with premalignant epithelial cells into mice results in malignancy. On the other hand, senescent human melanocytes secrete a protein that induces replicative arrest in a fair percentage of melanoma cells. In all experiments tissue types must be taken into account, of course. Some of the hallmarks of inflammation are elevated levels of IL-6, IL-8, and TNF-α. Inflammatory oxidative damage is carcinogenic and an inflammatory microenvironment is a good breeding ground for malignancies.

Caloric restriction extends lifespan in part by inhibiting TOR/mTOR (target of rapamycin/mechanistic target of rapamycin, also called  the mammalian target of rapamycin). TOR is a sort of metabolic manager, it receives inputs regarding the availability of nutrients and stress levels and then acts accordingly. Metformin is also a TOR inhibitor, which is why it is being investigated as a cancer shield and a longevity aid. Rapamycin has extended average lifespans in all species tested thus far and reduces geroconversion. It also restores the self-renewal and differentiation capacities of haemopoietic stem cells. For these reasons the Major Mouse Testing Program is using rapamycin as its positive control. mTOR and p53 dance (or battle) with each other beautifully in what Hasty calls the “Clash of the Gods.” While p53 inhibits mTOR1 activity, mTOR1 increases p53 activity. Since neither metformin nor rapamycin are without their share of unwanted side effects, more senolytics must be explored in greater detail.

Starting with a simple premise, namely that senescent cells rely on anti-apoptotic and pro-survival defenses more than their actively replicating counterparts, Campisi and her colleagues created a series of experiments to find the “Achilles’ Heel” of senescent cells. After comparing the two different cell states, they designed senolytic siRNAs. 39 transcripts were selected for knockdown by siRNA transfection, and 17 affected the viability of their target more than healthy cells. Dasatinib, a cancer drug, and quercitin, a common flavonoid found in common foods, have senolytic properties. The former has a proven proclivity for fat-cell progenitors, and the latter is more effective against endothelial cells. Delivered together, they they remove senescent mouse embryonic fibroblasts. Administration into elderly mice resulted in favorable changes in SA-BetaGAL (a molecule closely associated with SASP) and reduced p16 RNA. Single doses of D+Q together resulted in significant improvements in progeroid mice.

If you are not titillated yet, please embark on your own journey through the gallery of encroaching options for those who would prefer not to become chronically ill, suffer immensely, and, of course, die miserably in a hospital bed soaked with several types of their own excretions―presumably, hopefully, those who claim to be unafraid of death have never seen this image or naively assume they will never be the star of such a dismal and lamentably “normal” final act. There is nothing vain about wanting to avoid all the complications that come with time. This research is quickly becoming an economic and humanitarian necessity. The trailblazers who move this research forward will not only find wealth at the end of their path, but the undying gratitude of all life on earth.

Japan Liberalizes Gene Therapy and Regenerative Medicine – Article by Alex Tabarrok

Japan Liberalizes Gene Therapy and Regenerative Medicine – Article by Alex Tabarrok

******************************

Japan is liberalizing its approval process for regenerative medicine:

Regenerative medicines in Japan can now get conditional marketing approval based on results from mid-stage, or Phase II, human trials that demonstrate safety and probable efficacy.

Once lagging behind the United States and the European Union on approval times, there is now an approximately three-year trajectory for approvals, according to Frost’s Kumar. That compares with seven to 10 years before. …

Around the world, companies have also faced setbacks while pushing such treatments. In the U.S., Geron Corp., which started the first nation-approved trial of human embryonic stem cells, ended the program in 2011, citing research costs and regulatory complexities. …

While scientists globally have worked for years in this field, treatments have been slow to come to market. But there is hope in Japan that without the political red tape, promising therapies will emerge faster and there will be speedier rewards.

Japan is liberalizing because with their aging population treatments for diseases like Alzheimer’s and Parkinson’s disease are in high demand.

Under the new system, a firm with a gene or regenerative therapy (e.g. stem cells) can get conditional approval with a small trial. Conditional approval means that the firm will be able to sell its procedure while continuing to gather data on efficacy for a period of up to seven years. At the end of the seven-year period, the firm must either apply for final marketing approval or withdraw the product.

The system is thus similar to what Bart Madden proposed for pharmaceuticals in Free to Choose Medicine.*

Due to its size and lack of price controls, the US pharmaceutical market is the most lucrative pharmaceutical market in the world.

Unfortunately, this also means that the US FDA has an outsize influence on total world investment. The Japanese market is large enough, however, that a liberalized approval process if combined with a liberalized payment model could increase total world R&D.

Breakthroughs made in Japan will be available for the entire world so we should all applaud this important liberalization.

* Editor’s note from the Foundation for Economic Education: There may well by a direct connection here. According to Madden, an early version of his proposal in Free to Choose Medicine was published in a booklet by the Heartland Institute, which was then translated and distributed in Japan by a Japanese free-market think tank.

******************************

Pharmaceutical drug manufacturers are often regarded as the successes of the intellectual property regime. It is assumed that their willingness to take risks by investing heavily in R&D is justified by the awarding of patents over their lifesaving discoveries. Proponents of intellectual property claim that without patents many lifesaving drugs would not exist. They assert that generic drug manufacturers would diminish profit margins and dissipate the original manufacturer’s market share and innovation would come to a virtual standstill. Further, manufacturers once willing to create new drugs will no longer do so without sufficient returns on investment. Research into the matter suggests, however, that patent protection may not be required for medical advances.

Unpatented Medical Technologies

The notion that unpatented medical technologies are not feasible is historically false. Surveys of important medical breakthroughs provide insight into whether patents are absolutely necessary and conducive to innovation in medicine. In 2006, the British Medical Journal challenged its readership to submit a list of the most noteworthy medical and pharmaceutical inventions throughout history. The original list contained over 70 different discoveries before being narrowed down to 15. The list goes as follows in no particular order: penicillin, x-rays, tissue culture, ether anesthetic, chlorpromazine, public sanitation, germ theory, evidence-based medicine, vaccines, the pill, computers, oral rehydration therapy, DNA structure, monoclonal antibody technology, and smoking health risk. Of these discoveries, only two of them have remotely anything to do with patents, chlorpromazine and the pill.[1] In another survey conducted by the United States Centers for Disease Control the results are strikingly similar. Of the ten most important medical discoveries of the twentieth century, none of them had anything to do with patents.[2]

Natural Market Advantages and Trade Secrecy

Contrary to popular belief, large pharmaceutical companies may maintain significant market share advantages after the introduction of generics through the help of natural barriers to entry. Large pharmaceutical companies have a first-mover advantage and an established internal and external structure that competitors, large and small, do not. Regardless of how fast competitors can manufacture a generic drug (never mind the fact that they must hire new labor, train new employees, buy raw materials, establish suppliers, organize logistics, create a marketing and advertising plan, and set up competitive shelf space), it can be extremely difficult to make a dent in the market dominance of an already-established drug. Competition data from India suggests that it takes approximately four years for generic drugs to enter the market.[3] In addition, the Congressional Budget Office calculated that an original drug manufacturer could still maintain a market share of more than 20 percent after the introduction of generics. Expanding the scope of research beyond pharmaceutical drugs, a survey of R&D labs and company managers revealed that between 23 percent and 35 percent believe a patent is an effective way of getting a return on investment. At the same time 51 percent believe trade secrets to be an effective way of ensuring returns.[4]

The Truth about R&D Costs and Generic Drugs

Pharmaceutical drug manufacturers enjoy large margins in spite of large R&D. The claim that R&D for pharmaceuticals is high is not unfounded. The cost to bring a new drug to market varies between estimates of $402 million on the lower end and $800 million on the upper end.[5],[6] Regardless of high R&D costs, drug companies still command high margins. For the past two decades pharmaceutical drugs have been one of the most profitable industries in the United States, never dropping below third place.[7] The profitability of pharmaceuticals can be explained away under the assumption that people are living longer and consuming more pharmaceutical drugs. It may also be suggested that the human population is less healthy than in the past and the demand for pharmaceutical drugs is inelastic. But, analysis of the profit margin on pharmaceutical drugs and lack of any serious innovation suggests that this is not always the case.

The pharmaceutical industry globally maintains about a 25 percent operating margin as opposed to 15 percent for consumer goods. In the United States, this number achieved its zenith at almost 35 percent. The high margin on the drugs may not be due directly to high R&D costs, either. As of 2006, the ratio of R&D to sales revenue was about 0.19.[8] Further, the top 30 pharmaceutical firms in the world incur costs for promotions and advertising that are nearly double the costs of R&D. This is not to imply that there is a perfect amount of R&D spending each firm must do, rather it is to show that the inability to recoup R&D costs is greatly exaggerated.

Generic drugs are not just manufactured by small companies that seek to ride on the coattails of the giants. It is believed that generics add nothing innovative to the realm of lifesaving drugs, they merely manufacture competing drugs that are already in the public domain; the real innovation comes from the companies willing to invest in research and development. The National Institute of Health Care Management conducted a survey of drugs that received approval from the FDA from 1989 to 2000 with revealing results. Just over half the drugs in the survey, 54 percent, were using active ingredients that were already in use in the market. Of the drugs that were approved by the FDA, 23 percent were given a priority rating on the basis that they were a sufficient clinical improvement compared to existing alternatives. As a corollary, 77 percent of the approved drugs did not exhibit any kind of significant clinical improvement.[9] In other words, these drugs are functionally generic drugs, offering no kind of advantage over existing treatments. Large drug companies are ironically engaging in the kind of behavior they abhor by developing functionally generic drugs while wasting valuable R&D resources.

Conclusion

In a truly free market, whoever has the resources to manufacture an invention is permitted to do so, and the firms that enter the market first with a new drug enjoy a significant advantage. Moreover, the fact remains that the best way to protect an idea is to keep it a secret, which is why the trade-secret method remains effective. The federal government, however, has made it profitable to conclude that the best way to protect an idea is twisting the wrists and shoulders of one’s competitors with government force. Yet in spite of overwhelming federal-government intervention, innovation and ingenuity prevail, even if to a lesser degree.

The FDA: A Pain From the Neck to the Big Toe – Article by Mark Thornton

The FDA: A Pain From the Neck to the Big Toe – Article by Mark Thornton

******************************

I recently experienced severe pain in my feet, particularly in the big toes. In my imagination it felt like my feet had been run over by a truck and that several of my toes had been broken. But I knew that was not the case, and that the pain came on slowly at first, and then spread to other parts of my feet until I could barely walk.

My first approach was to take some ibuprofen to relieve the pain and swelling. When this did not resolve the matter, I thought perhaps a new pair of soft shoes might work. That idea also failed, and with a little internet research I realized I had a classic case of the gout. I was soon off to see my doctor to determine what the problem was and to get it solved with the powers of modern medicine.

The doctor confirmed that I had the gout. I was not pleased to find out, that in my case, the gout was probably brought on by another drug that I had been taking daily, against my better judgment. However, I was pleased to learn that I would no longer have to take it, that as part of my treatment I was being prescribed an ancient and natural drug, and that I would only have to take this drug “as needed.”

I was off to get my prescription filled at the pharmacy when a thought came to mind: if this drug was as natural and ancient as advised by my doctor, why did I need a prescription in the first place? Upon inspection the prescription was for Colcrys, the brand name of the drug colchicine. Furthermore, when I picked up my prescription the price was much higher than I anticipated given that it was a natural drug. When questioned, the pharmacy technician replied that the actual price was much higher and that my insurance paid for more than three-quarters of the bill. The cash price (without insurance) was $198.99 which is $6.63 per pill if taken daily, or nearly $20 per dose if used to treat flare-ups.

An extremely high price for an ancient natural drug? I knew I had a new case to solve and that the solution was probably the same old answer.

After conducting some research on Wikipedia, I learned the following: Colchicine can be used to treat gout, Behcet’s disease, pericarditis, and the Mediterranean fever. It has been in use as a medicine for over 3,000 years. After serving as ambassador to France, Benjamin Franklin brought colchicum plants back to America in order to treat his own gout. Modern science has further refined the drug for better medicinal use.

Colcrys has been used to treat gout for a very long time, although the Food and Drug Administration (FDA) had not approved Colcrys specifically for the treatment of gout prior to 2009. Alternative drugs, such as Allopurinal, are also used to treat gout and related ailments. Until recently, you could treat your own gout using one of these medicines for pennies a day.

In the summer of 2009, the Food and Drug Administration approved Colcrys as a treatment for gout flare-ups and the Mediterranean fever. The FDA gave pharmaceutical company URL Pharma an exclusive marketing agreement for selling Colcrys in exchange for completing studies on Colcrys and paying the FDA a $45 million application fee.

This deal effectively created a patented drug with no generic alternative. Therefore it gave the company a monopoly for the duration of the agreement. URL Pharma immediately raised the price from less than a dime to nearly $5 dollars per pill. Comprehensive medical insurance does substantially reduce the price to consumers, but it does not reduce the cost. Insurance only spreads the cost-burden across policy holders.

At the same time, doctors are encouraged by pharmaceutical companies to employ more expensive and profitable treatments. As a result the overall cost burden increases. Evidence suggests that doctors are prescribing Colcrys in large volumes to treat gout flare-ups and as a long-term preventative measure.

Once again the federal government has taken something that was both cheap and beneficial and turned it into a monopoly that hurts the general public and drives up the cost of medical care to the benefit of Big Pharma.

Note: Just because it is natural and produced in a pharmaceutical environment, does not mean that Colcrys is harmless. It can be considered toxic in large amounts, has a long list of possible side effects, and is not recommended for people with certain conditions.
