The future (of medicine) is biology

It was once quite convenient for manufacturers of deluxe medical widgets to worry only about other manufacturers of deluxe medical widgets. Manufacturers must now widen their perspective to consider current and future competition (and opportunity) from whatever direction it may come. –> Just thought I might chime in and suggest that, if you do make such widgets, it might be a good idea to maybe throw at least an occasional sidelong glance at biotech. (Most of you are, great, but some of you think biotech is too far away to compete…)

Organ Bioengineering is years away and poses little challenge to medical devices …FALSE.  Urinary bladders have been engineered for pediatric applications. Bioengineered skin (the “integumentary” organ) is now routinely bioengineered for burns, chronic wounds, and other wound types. Across a wide range of tissue types (bone, cardiac, smooth muscle, dermal, etc.) scientists — clinicians — have rapidly developed technologies to direct the construction and reconstruction of these tissues and restore their structure and function.

Cell Biology. Of course cells are engineered into tissues as part of the science of tissue engineering, but combine this with advances in engineering not just between cells but between cells AND within cells and (…sound of my head exploding). With the sum of the understanding and capacity to control we have gained over cellular processes over the past few decades now rapidly accelerating, medical science is fast approaching the point at which it can dictate outcomes for cell, tissues, organs, organ systems, and humans (I am not frightened, but excited, with caution).  Our understanding and proficiency gained in manipulating processes from cell division to pluripotency to differentiation to senescence to death OR NOT has profound consequences for fatal, debilitating, incurable, devastating, costly, and nearly every other negative superlative you can conceive.

CRISPR*: This is a new, relatively simple, but extraordinary tool allowing researchers or, more importantly, physicians to potentially swap out defective genes with healthy ones. See Nature.

Biotech has, over its history, often succeeded in getting attention, but has had less success justifying it, leaving investors rudely awakened to its complexities.  It has continued, however, to achieve legitimately exciting medical therapeutic advances, if only as stepping stones in the right direction, like mapping the human genome, the development of polymerase chain reaction (“PCR”), and biotech-driven advances in molecular biology, immunology, gene therapy, and others, with applications ripe for exploitation in many clinical specialties, Sadly, the agonizing delay between advanced and “available now” has typically disappointed manufacturers, investors, clinicians and patients alike. CRISPR and other tools already available (see Genetic Engineering News and others) are poised to increase the expectations – and the pace toward commercialization – in biotechnology.

Vaccines and Infectious Disease: Anyone reading this who has been under a rock for lo these many years, blissfully ignorant of SARS, Ebola, Marburg, MRSA, and many other frightening acronyms besides HIV/AIDS (more than enough for us already) should emerge and witness the plethora of risks we face (and self-inflict through neglect), any one of which might ultimately overwhelm us if not medically then economically in their impacts. But capitalists (many altruistic) and others have come to the rescue with vaccines such as for malaria and dengue-fever and, even, one for HIV that is in clinicals.

Critical Mass, Synergies, and Info Tech. Biotechnology is succeeding in raising great gobs of capital (if someone has a recommended index/database on biotech funding, let me know?).  Investors appear to be forgetful increasingly confident (in the 1990s, I saw big layoffs in biotech because of ill-advised investments, but that was then…) that their money will result in approved products with protected intellectual property and adequate reimbursement and manageable costs in order to result in attractive financials. The advances in biological and medical science alone are not enough to account for this, but such advances are almost literally being catalyzed by information technologies that make important connections faster, yielding understanding and new opportunities. The net effect of individual medically-related disciplines (commercial or academic) advancing research more efficiently as a result of info tech and info sharing/synergies between disciplines is the expected burst of medical benefits ensuing from biotech. (Take a look also at Internet of DNA.)

Reconstructive surgery is increasingly aesthetic

Given the volume of the non-clinically-indicated aesthetic procedures, and their increasingly sophisticated techniques and technologies, reconstructive surgery specialists have integrated aesthetics advances and can now achieve spectacular results that go well beyond the simple reconstructive procedures of the past, which were much less effective in concealing the trace evidence of disease and trauma.

Reconstructive surgery is the subset of “plastic” surgery focused on correcting the anatomy, aesthetics, or both, for patients who have been treated for disease or trauma, which sets it apart from purely aesthetic procedures performed for people wishing to improve their appearance above and beyond what they were given by birth (excluding congenital defects) or to reduce the signs of aging.

Given the volume of the non-clinically-indicated aesthetic procedures, and their increasingly sophisticated techniques and technologies, reconstructive surgery specialists have integrated aesthetics advances and can now achieve spectacular results that go well beyond the simple reconstructive procedures of the past, which were much less effective in concealing the trace evidence of disease and trauma.

By far, the most common reconstructive procedures are to address the physical appearance resulting from the removal of tumors. In the U.S. alone, reconstruction for tumor removal is performed over 4 million times annually. The remainder of reconstructive procedures covers a gamut of major and minor trauma and diseases.

Below is the distribution of non-aesthetic (only) reconstructive procedures in the U.S.

Through 2018, the global medical reconstructive and aesthetic products market is expected to reach a value of about $10.7 billion. Energy-based products such as lasers will experience the highest growth level. In most geographical regions and particularly in the U.S. and Europe, there is a growing consumer demand for medical cosmetic procedures and through 2020, even the lower income groups are likely to demand for more procedures, as the treatments become increasingly main stream. During the past few years, practitioners in the U.S. were rather forced to implement discounts and now with the revival of the economy, the total fee growth is likely to rebound. Successful companies in the sector mostly rely on a formula for continued research and development, pursuing additional, new business opportunities to increase expertise and product offerings. These companies remain solidly active in the eyes of high-end dermatologists, plastic and cosmetic surgeons.  As the aesthetic market is all about new products, the companies will be left behind, if they do not come up a new product every now and then.

Tissue Engineering and Cell Therapy Market Outlook

The market for tissue engineering and cell therapy products is set to grow to nearly $32 billion by 2018. This figure includes bioengineered products that are themselves cells or are actively stimulating cell growth or regeneration, products that often represent a combination of biotechnology, medical device and pharmaceutical technologies. The largest segment in the overall market for regenerative medicine technologies and products comprises orthopedic applications. Other key sectors are cardiac and vascular disease, neurological diseases, diabetes, inflammatory diseases and dental decay and injury.

An overview (map) of the spectrum of clinical applications in tissue engineering and cell therapy is shown below:

Source: Report #S520

Cell therapy is defined as a process whereby new cells are introduced into tissue as a method of treating disease; the process may or may not include gene therapy. Forms of cell therapy can include: transplantation of autologous (from the patient) or allogeneic (from a donor) stem cells , transplantation of mature, functional cells, application of modified human cells used to produce a needed substance, xenotransplantation of non-human cells used to produce a needed substance, and transplantation of transdifferentiated cells derived from the patient’s differentiated cells.

Once considered a segment of biomaterial technologies, tissue engineering has evolved into its own category and now comprises a combination of cells, engineering and suitable biochemical and physiochemical factors to improve or replace biological functions. These include ways to repair or replace human tissue with applications in nearly every medical specialty. Regenerative medicine is often synonymous with tissue engineering but usually focuses on the use of stem cells.

Tissue engineering and cell therapy may be considered comprised of bioengineered products that are themselves cells or are actively stimulating cell growth or regeneration. These often comprise a combination of biotechnology, medical device and pharmaceutical technologies.

Researchers have been examining tissue engineering and cell therapy for roughly 30 years. While some products in some specialties (such as wound care) have reached market, many others are still in research and development stages. In recent years, large pharmaceutical and medical device companies have provided funding for smaller biotech companies in the hopes that some of these products and therapies will achieve a highly profitable, commercial status. In addition, some companies have been acquired by larger medical device and pharmaceutical companies looking to bring these technologies under their corporate umbrellas. Many of the remaining smaller companies received millions of privately funded dollars per year in research and development. In many cases it takes at least ten years to bring a product to the point where human clinical trials may be conducted. Because of the large amounts of capital to achieve this, several companies have presented promising technologies only to close their doors and/or sell the technology to a larger company due to lack of funds.

The goal of stem cell research is to develop therapies to treat human disease through methods other than medication. Key aspects of this research are to examine basic mechanisms of the cell cycle (including the expression of genes during the formation of embryos) as well as specialization and differentiation into human tissue, how and when the differentiation takes place and how differentiated cells may be coaxed to differentiate into a specific type of cell. In the differentiation process, stem cells are signaled to become a specific, specialized type of cell when internal signals controlled by a cell’s genes are interspersed across long strands of DNA and carry coded instructions for all the structures and functions of a cell. In addition, cell differentiation may be caused externally by use of chemicals secreted by other cells, physical contact with neighboring cells and certain molecules in the microenvironment.

The end goal of stem cell research is to develop therapies that will allow the repair or reversal of diseases that previously were largely untreatable or incurable.. These therapies include treatment of neurological conditions such as Alzheimer’s and Parkinson’s, repair or replacement of damaged organs such as the heart or liver, the growth of implants from autologous cells, and even regeneration of lost digits or limbs.

In a developing human embryo, a specific layer of cells normally become precursor cells to cells found only in the central nervous system or the digestive system or the skin, depending on the cell layer and the elements of the embryo that direct cell differentiation. Once differentiated, many of these cells can only become one kind of cell. However, researchers have discovered that adult body cells exist that are either stem cells or can be coaxed to become stem cells that have the ability to become virtually any type of human cell, thus paving the way to engineer adult stem cell that can bring about repair or regeneration of tissues or the reversal of previously incurable diseases.

Another unique characteristic of stem cells is that they are capable of self-division and self-renewal over long periods of time. Unlike muscle, blood or nerve cells, stem cells can proliferate many times. When exposed to ideal conditions in the laboratory, a relatively small sample of stem cells can eventually yield millions of cells.

There are five primary types of stem cells: totipotent early embryonic cells (which can differentiate into any kind of human cell); pluripotent blastocyst embryonic stem cells, which are found in an embryo seven days after fertilization and can become almost any kind of cell in the body; fetal stem cells, which appear after the eighth week of development; multipotent umbilical cord stem cells, which can only differentiate into a limited number of cell types; and unspecialized adult stem cells, which exist in already developed tissue (commonly nerves, blood, skin, bone and muscle) of any person after birth.

Developmental Timescales

Tissue engineering and cellular therapy products take years of research and many millions of dollars (averaging about $300 million, according to some reports) before they make it over the hurdles of clinical trials and into actual market launch. More than one small biotech company has burned through its money too quickly and been unable to attract enough investment to keep the doors open. The large pharmaceutical and medical device companies are watching development carefully, and have frequently made deals or entered into alliances with the biotechs, but they have learned to be cautious about footing the bill for development of a product that, in the end, may never sell.

For many of the products in development, product launch is likely to occur within five years. Exceptions include skin and certain bone and cartilage products, which are already on the market. Other products are likely to appear on the European market before launch in the United States, due to the presence of (so far) less stringent product review and approval laws in the European Union.

Even when the products are launched, take-up will be far from 100% of all patients with that particular condition. Initially, tissue engineering and cell therapy products will go to patients suffering from cancers and other life-threatening conditions, who, for example, are unable to wait any longer for a donor organ. Patients who seem to be near the end of their natural lives likely will not receive these treatments. Insurance coverage will certainly play a key role as well in the decision about who receives which treatments and when. But most importantly, physicians will be selecting who among their patients will be treated; the physicians learn about the treatments by using them, by observing the patient’s reactions, and by discussing their experiences with colleagues. In other words, the application of tissue engineering and cellular therapy will progress in a manner similar to the introduction of any new technology: through generally conservative usage by skilled, highly trained physicians dedicated to providing their patients with the best possible treatment without causing them additional harm.

Applications, global markets in tissue engineering and cell therapy

Screen Shot 2014-04-17 at 7.37.44 AMThe market for tissue engineering and cell therapy products is set to grow from a respectable $8.3 billion in 2010 to nearly $32 billion by 2018. This figure includes bioengineered products that are themselves cells or are actively stimulating cell growth or regeneration, products that often represent a combination of biotechnology, medical device and pharmaceutical technologies. The largest segment in the overall market for regenerative medicine technologies and products comprises orthopedic applications. Other key sectors are cardiac and vascular disease, neurological diseases, diabetes, inflammatory diseases and dental decay and injury.

Cell-tissue-applications

Factors that are expected to influence this market and its explosive growth include political forces, government funding, clinical trial results, industry investments (or lack thereof), and an increasing awareness among both physicians and the general public of the accessibility of cell therapies for medical applications. Changes in the U.S. government’s federal funding of embryonic stem cell research has given a potentially critical mass of researchers increased access to additional lines of embryonic stem cells. This is expected to result in an increase in the number of research projects being conducted and thus possibly hasten the commercialization of certain products.

Another factor that has influenced the advancement of regenerative technologies is found in China, where the Chinese government has encouraged and sponsored cutting-edge (and some have complained ethically questionable) research. While China’s Ministry of Health has since (in May 2009) established a policy requiring proof of safety and efficacy studies for all gene and stem cell therapies, the fact remains that this research in China has spurred the advancement of (or at least awareness of) newer applications and capabilities of gene and stem cell therapy in medicine.

Meanwhile, stricter regulations in other areas of Asia (particularly Japan) will serve to temper the overall growth of commercialized tissue and cell therapy–based products in that region. Nonetheless, the growth rate in the Asia/Pacific region is expected to be a very robust 20% annually.

Growth in Sales of Products in Cell Therapy and Tissue Engineering

Tissue engineering and cell therapy comprise a market for regenerative products that has been growing and will continue to grow at over 20% annually through 2018. This market spans many specialties, the biggest of which is therapies for degenerative and traumatic orthopedic and spine applications. Other disorders that will benefit from cell therapies include cardiac and vascular disease, a wide range of neurological disorders, diabetes, inflammatory diseases, and dental decay and/or injury. Key factors expected to influence the market for regenerative medicine are continued political actions, government funding, clinical trials results, industry investments, and an increasing awareness among both physicians and the general public of the accessibility of cell therapies for medical applications.

The current high rate of growth in cell therapy and tissue engineering product sales is due to the confluence of multiple market drivers:

  • Advances in basic science revealing the nature of cell growth, differentiation and proliferation
  • Advances by industry to manipulate and determine cell growth toward specific therapeutic solutions
  • Low barrier to entry for competitors in the market
  • Broad range of applications of cell/tissue advances to many different specialties with modest adaptation needed
  • Strong venture funding

The dominant clinical area driving cell therapy and tissue engineering product sales is orthopedics and musculoskeletal, wherein bone grafts and bone graft substitutes are well-established. Below is the projected balance of cell therapy and tissue engineering product revenues by clinical area through 2018.

The increasing problem of chronic wounds, and their medtech solutions

Wounds have many different sources, etiologies and forms and, therefore, demand a range of approaches. By virtue of these differences, they have considerably different costs. At the top of the list of wound culprits driving up cost is the category of chronic wounds. Simply put, these wounds are very slow to heal due to poor circulation at the site (e.g., decubitus stasis, or pressure, ulcers), concomitant health issues (diabetes) and the difficulty in changing the local environment toward one with conditions more conducive to the healing process.

Chronic wounds are not the most common — that is a category represented by surgical wounds, in which the wound has been created medically or surgically in order to excise or otherwise manage diseased tissue. But surgical wounds, traumatic wounds and lacerations are by their nature acute and, especially for surgical wounds, can be surgically managed to create clean wound edges, good vascularization and other conditions that accelerate healing. Therefore, while the volume of surgical and traumatic wounds and lacerations is significant, their costs are manageable and their growth is unremarkable.

But the costs of chronic wounds are higher due to both the types of different products required and the length of time required for those products to be used. Moreover, given the association of chronic wounds with conditions that are growing in prevalence due to increasing incidence of obesity, diabetes and other conditions, combined with an aging population that is increasingly sedentary, the prevalence of chronic wounds is shifting the balance among wound types. Below is the balance of wound types by prevalence worldwide in 2011, followed by the projected balance of wound types in 2025.

Surgical wounds offer the potential for use of devices which can ensure hemostasis, prevent internal adhesions and anastomoses, secure soft tissue, and close the skin. Traumatic wounds also offer potential for skin closure products and for hemostats, and adhesion prevention during post-trauma surgery. New wound-covering sealant products may also offer potential for treatment of cuts, grazes, and burns.

Chronic wounds are generally not amenable to treatment by adhesives, sealants and hemostats unless the wound has either been debrided to a sterile bleeding surface (in which case it becomes like a surgical wound), or the product offers some stimulant activity. Many hemostats exhibit some inflammatory and cytokinetic activity, which has been associated with accelerated healing. However, this inflammatory activity has also been known to burn the patient’s skin. Chronic wounds are instead dealt with often by a combination of debridement, frequent dressing changes, products to address local vascular circulation and pressure (negative and positive) and others. Progress is being made in reducing the associated healing times, but a large opportunity remains.
