Naturally sticky: Biologically-based medical glues dominate

Medical glues are either biologically-based, cyanoacrylate, or other synthetic. The bulk of global sales of medical glues are biologically-based, (includes fibrin, thrombogen, and others), cyanoacrylate-based glues, and other synthetic glues.

Cyanoacrylate-based glues, include those from Ethicon, Adhezion Biomedical, B. Braun, Meyer-Haake, and others. Cyanoacrylates provide strong adhesion, but biologically-based glues have found more applications, both topically and internally. “Other” glues are of a variety of synthetic types; these glues have yet to gain more than 4% share globally.

Below is illustrated the growth of biologically-based glues by region, showing that most growth in this segment will be from Asia/Pacific markets, which are consistently demonstrating higher growth than in western markets.

What’s next in sealants, glue, hemostats…and why?

From July 2016 published Report #S290.

Here are six key trends we see in the global market next in surgical sealants, glues, and hemostats:

  1. Aggressive development of products (including by universities, startups, established competitors), regulatory approvals, and new product introductions continues in the U.S., Europe, and Asia/Pacific (mostly Japan, Korea) to satisfy the growing volume of surgical procedures globally.
  2. Rapid adoption of sealants, glues, hemostats in China will drive much of the global market for these products, but other nations in the region are also big consumers, with more of the potential caseload already tapped than the rising economic China giant. Japan is a big developer and user of wound product consumer. Per capital demand is also higher in some countries like Japan.
  3. Flattening markets in the U.S. and Europe (where home-based manufacturers are looking more at emerging markets), with Europe in particular focused intently on lowering healthcare costs.
  4. The M&A, and deal-making that has taken place over the past few years (Bristol-Myers Squibb, The Medicines Company, Cohera Medical, Medafor, CR Bard, Tenaxis, Mallinckrodt, Xcede Technologies, etc.) will continue as market penetration turns to consolidation.
  5. Growing development on two fronts: (1) clinical specialty and/or application specific product formulation, and (2) all purpose products that provide faster sealing, hemostasis, or closure for general wound applications for internal and external use.
  6. Bioglues already hold the lead in global medical glue sales, and more are being developed, but there are also numerous biologically-inspired, though not -derived, glues in the starting blocks that will displace bioglue shares. Nanotech also has its tiny fingers in this pie, as well.

Market positions in sealants, glues, hemostats fluid in U.S., Europe, Asia/Pacific

Market shares for sales of sealants, glues, and hemostats vary considerably from region to region globally due to the significant variations in the local market demand, rate of adoption of specific manufacturers’ products, the regulatory climate, local economies, and other factors. Consequently, manufacturers with significant share of sales in the U.S. or Europe or Asia/Pacific may have considerably lower or higher shares in other regions.

In the U.S., Ethicon and Baxter have dominant positions in sales of surgical sealants. However, in Europe and Asia/Pacific, Baxter has substantially smaller position, particularly relative to competitors like Takeda Pharmaceuticals and The Medicines Company.

Untapped potential for sealants, glues, hemostats in wound caseloads and procedures

Today’s surgeon has a broad range of products from which to choose for closing and sealing wounds. These include sutures, stapling devices, vascular clips, ligatures, and thermal devices, as well as a wide range of topical hemostats, surgical sealants and glues.

However, surgeons still primarily use sutures for wound closure and securement—sutures are cheap, familiar and work most of the time. Now, in addition to reaching for a stapling device, the surgeon must frequently decide at what point to augment or replace the commonly used items in favor of other products, which product is best for what procedure or condition, how much to use, and ease of use in order to achieve optimal patient outcomes. Because of budget pressures, the surgeon must also consider price when selecting a product. Of course in the USA, the product must also be FDA-approved, although the surgeon still has the choice of using a product off-label.

In the areas of sealants, hemostats and glues, there is room for both improvement and additional products.  There are a number of products already on the market, but the fact is that there is no one product that meets all needs in all situations and procedures. There are few products that stand out from the rest, apart, perhaps, from DermaBond® and BioGlue®. There are unmet needs, and companies having the necessary technology, or which may acquire and further develop the technology, can enter this market and launch novel items. These products have yet to significantly tap the potential for wound management and medical/surgical procedures.

Sealants, Fibrin and Others

Numerous variants of fibrin sealant exist, including autologous products. “Other” sealants refers to thrombin, collagen & gelatin-based sealants.

Fibrin sealants are used in the US in a wide array of applications; they are used the most in orthopedic surgeries, where the penetration rate is thought to be 25-30%. Fibrin sealants can, however, be ineffective under wet surgical conditions. The penetration rate in other surgeries is estimated to be about 10-15%.

Fibrin-based sealants were originally made with bovine components. These components were judged to increase the risk of developing bovine spongiform encephalopathy (BSE), so second-generation commercial fibrin sealants (CSF) avoided bovine-derived materials. The antifibrinolytic tranexamic acid (TXA) was used instead of bovine aprotinin. Later, the TXA was removed, again due to safety issues. Today, Ethicon’s (JNJ) Evicel is an example of this product, which Ethicon says is the only all human, aprotinin free, fibrin sealant indicated for general hemostasis. Market growth in the Sealants sector is driven by the need for improved biocompatibility and stronger sealing ability—in other words, meeting the still-unsatisfied needs of physician end-users.

High Strength Medical Glues

Similar to that of sealants, the current market penetration of glues in the US is about 25% of eligible surgeries. There are several strong points in favor of the use of medical glues: their use can significantly reduce healthcare costs, for example by reducing time in the surgical suite, reducing the risk of a bleed, which may mean a return trip to the OR, and general ease of use. Patients seem to prefer the glues over receiving sutures for external wound closure, as glues can provide a suture-free method of closing wounds. In addition, if glues are selected over sutures, the physician can avoid the need (and cost) of administering local anesthesia to the wound site.

Hemostats

Hemostats are normally used in surgical procedures only when conventional methics to stop bleeding are ineffective or impractical. The hemostat market offers opportunities as customers seek products that better meet their needs. Above and beyond having hemostatic agents that are effective and reliable, additional improvements that they wish to see in hemostat products include: laparoscopy-friendly; work regardless of whether the patient is on anticoagulants or not; easy to prepare and store, with a long shelf life; antimicrobial; transparent so that the surgeon continues to have a clear field of view; and non-toxic; i.e. preferably not made from human or animal materials.

Add tick cement to the list of natural adhesives pursued for medical applications

In past posts, we have reported on multiple naturally-occurring substances or methods for strong adhesion that are being investigated for their potential to be exploited for medical or surgical adhesion. These include adhesives from remora, mussels, geckos, crab shells, barnacles, Australian burrowing frogs, spider webs, porcupine quills, sandcastle worms, etc.

Researchers from MedUni Vienna and Vienna University of Technology are now investigating 300 different ticks for the “cement” used by the parasites to attach to hosts. The goal is to study the composition of the natural tick “dowel” used by the mouthparts of ticks and determine how it might serve as a template for new tissue adhesives.

The Vienna research also notes other natural adhesives are similarly being investigated for medical and surgical use:

Other potential “adhesive donors” are sea cucumbers, which shoot sticky threads out of their sac; species of salamander, which secrete extremely fast-drying adhesive out of skin glands, if attacked; or insect larvae, which produce tentacles or crabs, which can remain firmly “stuck,” even under water.

The incentive for studying natural adhesives is that they have been driven by evolution to provide strong adhesion without toxicity in various wet or dry conditions that are challenging for existing synthetic or existing natural glues (e.g., fibrin glues, cyanoacrylates, etc.). Surgical glues currently in use have some limitation arising from lesser strength, ease of use, toxicity, and other shortcomings. New glues will gain wider adoption, capturing procedure volume used with sutures, clips and other closure methods, particularly in internal use, if they are stronger and/or provide tighter seals (without needing to be combined with sutures on the same incision/wound) and do not cause the toxicity that some high strength medical glues do (e.g., synthetics like cyanoacrylates; “super glues”). The biologically-derived glues (or the surfaces structures of gecko feet) avoid the toxicities of synthetics and have often proven to have very high tensile strength. (The fast-curing cement used by barnacles has been shown to have a remarkable tensile strength of 5,000 pounds per square inch.)

Hemostat sales growth and opportunity

Hemostats are normally used in surgical procedures only when conventional bleeding control methods are ineffective or impractical. The hemostat market offers opportunities as customers seek products that better meet their needs. Above and beyond having hemostats that are effective and reliable, additional improvements that clinicians wish to see in hemostat products include:

  • laparoscopy-friendly
  • work regardless of whether the patient is on anticoagulants or not
  • easy to prepare and store, with a long shelf life
  • antimicrobial
  • transparent so that the surgeon continues to have a clear field of view
  • non-toxic
  • preferably not made from human or animal materials.

Wound Hemostasis, Closure, and Sealing in the U.S. versus Asia/Pacific, 2015-2022

Sales of sealants, glues, and hemostats projected to 2022 for the U.S. and Asia/Pacific. While these products have had tremendous success in Japan, their sales in the rest of Asia/Pacific have not yet caught up to Japan, let alone to the U.S.

But that is expected to change as the most significant growth in these markets will indeed be coming from China, Korea, Australia, India, and elsewhere in these emerging markets.

Medical and Surgical Sealants, Glues, and Hemostats, to 2022

There are several different classes of surgical sealants, glues and hemostatic products used to prevent or stop bleeding, or to close a wound or reinforce a suture line. These include fibrin sealants, surgical sealants, mechanical hemostats, active hemostats, flowable hemostats, and glues. Both sealants and medical glues are increasingly used either as an adjunct to sutures or to replace sutures.

Medical Sealants

Fibrin sealants are made of a combination of thrombin and fibrinogen. These sealants may be sprayed on the bleeding surface, or applied using a patch. Surgical sealants might be made of glutaraldehyde and bovine serum albumin, polyethylene glycol polymers, and cyanoacrylates.

Sealants are most often used to stop bleeding over a large area. If the surgeon wishes to fasten down a flap without using sutures, or in addition to using sutures, then the product used is usually a medical glue.

Hemostatic Products

The surgeon and the perioperative nurse have a variety of hemostats from which to choose, as they are not all alike in their applications and efficacy. Selection of the most appropriate hemostat requires training and experience, and can affect the clinical outcome, as well as decrease treatment costs. Some of the factors that enter into the decision-making process include the size of the wound, the amount of hemorrhaging, potential adverse effects, whether the procedure is MIS or open surgery, and others.

Active hemostats contain thrombin products which may be derived from several sources, such as bovine pooled plasma purification, human pooled plasma purification, or through human recombinant manufacturing processes. Flowable-type hemostats are made of a granular bovine or porcine gelatin that is combined with saline or reconstituted thrombin, forming a flowable putty that may be applied to the bleeding area.
Mechanical hemostats, such as absorbable gelatin sponge, collagen, cellulose, or polysaccharide-based hemostats applied as sponges, fleeces, bandages, or microspheres, are not included in this analysis.

Medical Glues

Sealants and glues are terms which are often used interchangeably, which can be confusing. In this report, a medical glue is defined as a product used to bond two surfaces together securely. Surgeons are increasingly reaching for medical glues to either help secure a suture line, or to replace sutures entirely in the repair of soft tissues. Medical glues are also utilized in repairing bone fractures, especially for highly comminuted fractures that often involve many small fragments. This helps to spread out the force-bearing surface, rather than focusing weight-bearing on spots where a pin has been inserted.

Thus, the surgeon has a fairly wide array of products from which to choose. The choice of which surgical hemostat or sealant to use depends on several factors, including the procedure being conducted, the type of bleeding, severity of the hemorrhage, the surgeon’s experience with the products, the surgeon’s preference, the price of the product and availability at the time of surgery. For example, a product which has a long shelf life and does not require refrigeration or other special storage, and which requires no special preparation, usually holds advantages over a product which must be mixed before use, or held in a refrigerator during storage, then allowed to warm up to room temperature before use.

Regional Markets for Surgical Sealants, 2015 and 2022

The fastest growth in the sales of surgical sealants over the next decade will be in the Asia-Pacific region, driven primarily by very strong healthcare market growth in China, and reaching a CAGR (2016-2022) of at least 13.97%. The growth rate in China would be even higher, but will be dampened for the time being by the lack of surgeons trained in the proper use of these products, as well as the limitations of reaching a dispersed patient population. Nonetheless, the A/P share of the global sealants market will double in the next seven years!

Below illustrates the geographic distribution of surgical sealants (fibrin and others) in 2015.
