Arch Developments Progress

Arch Therapeutics Inc (OTCBB:ARTH) is moving steadily higher on accelerating volume after the Company announced favorable preclinical data from an independent study of AC5 Surgical Hemostatic Device(TM) versus a popular Fibrin Sealant.

On May 18 ARTH said it will be featured as a presenting company at the LD MICRO Invitational conference on Monday, June 1, 2015 at 3:30 PM PDT. The conference will be held at the Luxe Sunset Hotel in Bel Air, California.

Chief Executive Officer Terrence W. Norchi, MD will provide a corporate update, discuss planned upcoming milestones, and highlight some of the differentiating features of AC5, which is in the late stages of development.

The stock was the subject of a significant promotion last summer shortly after hitting the bb’s from The Bedford Report, The Paragon Report and Five Star Equities also responsible for the fairly successful recent promotion of ECAU which managed gains of well over 500%.

Arch Therapeutics Inc (OTCBB:ARTH) is a medical device company developing a novel approach to stop bleeding (hemostasis) and control leaking (sealant) during surgery and trauma care. Arch is developing products based on an innovative self-assembling peptide technology platform to make surgery and interventional care faster and safer for patients. Arch’s flagship development stage product candidate, known as the AC5 Surgical Hemostatic Device (TM), is being designed to achieve hemostasis in minimally invasive and open surgical procedures.

In April the Company announced an independent third party has obtained favorable data from a preclinical animal study that compared the hemostatic activity of AC5 with a popular and commercially available branded fibrin sealant that is indicated for use in controlling bleeding.

In this study, full thickness penetrating wounds were surgically created in rat livers, which are highly vascularized parenchymal organs, and then either AC5(TM) or the fibrin sealant was applied in order to stop the bleeding. The time to hemostasis (TTH), which is the time required to stop bleeding, was measured.

The average TTH after application of AC5 was significantly less than 30 seconds. The average TTH for the fibrin sealant was approximately 50% longer.

AC5 was maintained at room temperature without requiring cold storage, whereas the fibrin sealant was maintained frozen during storage, in accordance with its prescribing directions. This is a common constraint of many commercial hemostatic agents that are derived from blood-products. Such products also require a multi-step preparation procedure prior to use.

AC5 contains a self-assembling peptide comprising naturally occurring amino acids that are not sourced from humans or animals, whereas the fibrin sealant is made from pooled human plasma (blood product). Fibrin sealants and other products that are sourced from human or animal blood products can contain infectious agents, such as viruses and potentially the Creutzfeldt-Jakob disease (CJD) agent, which potentially can be transferred to a patient.

CryoLife Appeals Rare Injunction In Patent Case

CryoLife Inc. on Wednesday filed its notice of appeal to the Federal Circuit of a preliminary injunction barring its PerClot blood-clotting powder, one day after a Delaware federal judge ordered Medafor Inc. to pay CryoLife $100,000 in the event that any court finds the injunction was wrongly issued. 
C.R. Bard Inc. unit Medafor satisfied the test for securing a preliminary injunction, including showing a reasonable likelihood that it will succeed on the merits and would suffer irreparable harm if CryoLife's product remained on the market, U.S. District Judge Sue L. Robinson ruled last month, in a relatively rare instance of a judge granting a preliminary injunction in a patent case. On Wednesday, CryoLife filed its notice of appeal of the injunction to the Federal Circuit.

The judge said Medafor has represented that it is able to pay the $100,000 if the condition on the injunction is met and that CryoLife agreed with the representation, adding that the requirement was proper and adequate security for the injunction.

“Pursuant to Federal Rule of Civil Procedure 65(c), this court orders that if this court or another court of competent jurisdiction finds this preliminary injunction wrongfully enjoined CryoLife, Medafor shall pay CryoLife $100,000 within ten (10) days of the order vacating or reversing this injunction,” the judge said.

CryoLife's PerClot Topical, launched last fall, competes with a Medafor product called Arista that was approved by the U.S. Food and Drug Administration in 2006. Both are powders used to control bleeding when conventional methods are ineffective.

The dispute began in April, when CryoLife filed suit seeking declaratory judgment that PerClot Topical would not infringe Medafor's patent. Medafor responded by filing an infringement counterclaim and seeking a preliminary injunction. CryoLife began selling PerClot Topical last fall.

Judge Robinson found that Medafor had shown that CryoLife likely infringes and that CryoLife was unlikely to show that the patent is invalid.

Johnson & Johnson (JNJ) Announces Additional FDA Indication for EVARREST Fibrin Sealant Patch

Johnson & Johnson (NYSE: JNJ) announced the following Monday:

Unexpected and uncontrollable bleeding is an ongoing challenge for surgeons, including those who perform liver surgery. Based on recent data, the U.S. Food and Drug Administration has approved an additional indication for Ethicon's EVARREST Fibrin Sealant Patch, as an adjunct to hemostasis for control of bleeding during adult liver surgery. EVARREST is a novel convergence of biologics and medical device that rapidly and reliably stops problematic bleeding during surgery on the first attempt in indicated patients.

A problematic bleeding situation—involving bleeding that is more than routine and resistant to conventional means of control—is one of the most threatening complications of surgery1 and a frequent cause of negative patient outcomes, posing significant clinical and economic challenges.2,3 First attempts to control surgical bleeding using current hemostatic agents can fail up to 50 percent of the time.3

"The liver is a particularly hard-to-control bleed site during surgery, as blood loss is often higher and hemostasis may be difficult to achieve," said Krishna Athota, M.D.*, trauma and critical care surgeon at the University of Cincinnati College of Medicine. "This expanded indication for EVARREST reinforces this innovation's potential to make problematic bleeding situations routine, and could result in a paradigm shift in the treatment of bleeding during surgery."

EVARREST is a novel, bioabsorbable hemostat that delivers a powerful combination of hemostatic efficacy, adherence and mechanical strength.4,5,6 The unmatched mechanism of action behind EVARREST drives rapid and durable clot formation by augmenting the human coagulation system. The technology is comprised of a flexible composite patch, which contains embedded human biologics (human thrombin and fibrinogen), which are proteins involved in the natural clotting process.

Clinical studies demonstrate that EVARREST is greater than 94 percent effective in controlling bleeding across challenging patient types and surgical situations, compared to current standard of care (less than 53 percent).7,8,9 EVARREST provides a rapid, predictable solution for problematic bleeding, minimizing surgical procedure disruption.3,7,8

"We see EVARREST as a game changer—better equipping surgeons to handle bleeding, thereby potentially improving patient outcomes, reducing OR costs and providing peace of mind for the entire surgical staff," said Dan Wildman, Vice President of Global Franchise Strategy and Innovation for Ethicon.

EVARREST has been shown to deliver a cost savings compared with current standard of care, when taking into account hemostat cost, OR time, transfusion requirements and retreatment. The low rate of re-bleeding with EVARREST reduces the need for other hemostatic therapies.10

Medafor Injunction Holds Up US Perclot Topical

CryoLife, Inc. (NYSE: CRY), a leading medical device and tissue processing company focused on cardiac and vascular surgery, today provided an update on its ongoing litigation with C.R. Bard, Inc. and certain of its subsidiaries regarding PerClot. The U.S. District Court for the District of Delaware (the "Court") has allowed CryoLife's declaratory judgment lawsuit against C.R. Bard's Medafor, Inc. subsidiary ("Medafor") to proceed. The Court also granted Medafor's motion for a preliminary injunction with respect to CryoLife's marketing and sale of PerClot Topical in the U.S. CryoLife is currently awaiting the Court's order, which it expects will provide details regarding the scope of the injunction.
Pat Mackin, CryoLife President and Chief Executive Officer, said, "While we are disappointed with the District Court's ruling on the preliminary injunction motion, we continue to believe we have a strong case and remain focused on securing the best long-term outcome in the litigation for our shareholders. We remain on track to begin enrollment in our PerClot IDE clinical trial for surgical applications during the first half of 2015, which would position us for potential FDA approval in the second half of 2017."
In April 2014, CryoLife filed a declaratory judgment lawsuit against C.R. Bard and certain of its subsidiaries, including Medafor, requesting that the Court declare that CryoLife's manufacture, use, offer for sale, and sale of PerClot in the U.S. does not and would not infringe Medafor's U.S. Patent No. 6,060,461 (the "'461 Patent"). In addition CryoLife requested that the Court declare that the claims of the '461 Patent are invalid. In September 2014, Medafor filed a motion for a preliminary injunction against CryoLife.
The preliminary injunction applies to PerClot Topical, which is in the early stages of launch in the U.S. CryoLife included approximately$1.5 million in PerClot Topical sales in its previously announced 2015 financial guidance. At this low-volume level, the Company was anticipating the gross margin for PerClot Topical to be approximately breakeven. The Company's previously announced earnings per share guidance for 2015 included $3 million to $4 million in expense related to the litigation with C.R. Bard. The Company continues to expect that this represents the high end of potential litigation expenses for the year related to this matter, and it will re-assess its litigation strategy and provide appropriate updates to its financial guidance, if any, after receiving the Court's order.

Comparison of methods to achieve artery closure following coronary angiography

Stefanie Schulz-Schupke, M.D., of the Deutsches Herzzentrum Munchen, Technische Universitat, Munich, Germany and colleagues assessed whether vascular closure devices are noninferior (not worse than) to manual compression in terms of access site-related vascular complications in patients undergoing diagnostic coronary angiography. The study appears in the November 19 issue of JAMA, a cardiovascular disease theme issue.


Percutaneous (through the skin) coronary angiography and interventions have become a cornerstone in the diagnosis and treatment of coronary artery disease. A substantial proportion of the adverse effects associated with these procedures is related to access-site complications. The common femoral artery (a large artery in the groin) is still the most frequently used access site. After the procedure, closure of the artery access site is usually achieved by manual compression. Since the mid-1990s, however, vascular closure devices (VCDs) have been introduced into clinical practice with the aim of improving efficacy and safety. Different types of VCDs have been developed, including intravascular and extravascular. However, concern exists about the safety of VCDs in comparison with manual compression, according to background information in the article.
For this study, conducted at four centers in Germany, 4,524 patients undergoing coronary angiography via the common femoral artery were randomly assigned to receive an intravascular VCD (n = 1,509), extravascular VCD (n = 1,506), or manual compression (n = 1,509) to achieve hemostasis (defined as no bleeding or only light superficial bleeding and no expanding hematoma [a localized swelling filled with blood]). Before hospital discharge, imaging of the access site was performed in 4,231 (94 percent) patients.
The primary end point (the composite of access site-related vascular complications at 30 days after randomization with a two percent noninferiority margin) was observed in 208 patients (6.9 percent) assigned to receive a VCD and 119 patients (7.9 percent) assigned to manual compression (difference, -1.0 percent). In addition, the time to hemostasis was significantly shorter with VCD compared with manual compression; time to hemostasis was shorter with intravascular VCD vs extravascular VCD; and device failures were less frequent with intravascular VCD vs extravascular VCD.
The authors write that the results of this trial may represent an important development for the clinical use of these devices. "Overall, the increase in efficacy of VCD use, with no trade-off in safety, provides a sound rationale for the use of VCD over manual compression in daily routine."

Start-up pitches high-tech glue for surgical leaks

TEL AVIV — An Israeli medical-device start-up is tackling one of the most dangerous occurrences in surgery — and it's doing it with glue.

LifeSeal is a glue-like substance that augments and, in some surgeries like hernias, replaces the traditional and painful sealing procedures of staples, tacks and sutures.

The privately-owned Israeli company behind the high-tech glue, LifeBond, says it should help in the treatment of post-operative leaks in closures of gastrointestinal and other surgical wounds. Patients get back up to speed more quickly and are more comfortable as they do.

Orahn Preiss-Bloom, one of LifeBond's co-founders, says the company's proprietary materials, which combine gelatin and an enzyme and are delivered by an applicator, were inspired by two sources: research by Professor Gregory Payne at the University of Maryland and the use of the enzyme for food applications in Asia.

The company is backed by some of Israel's top venture-capital firms as well as by Robert Taub, a prominent medical-innovation investor. And the idea is strong enough that Johnson & Johnson (TICKER: JNJ), the New Jersey-based international health-care giant, has put money down on LifeBond.

The technology is currently in European clinical trials. And with an eye to entering the U.S. market as well, CEO Gideon Sturlesi and Preiss-Bloom are looking for partners and raising capital.

TWO CURRENT APPLICATIONS

Started in 2007 and employing 35 people from headquarters in Caesarea, Israel, LifeBond for now is focusing the technology's application on gastrointestinal surgery and bariatric weight-loss procedures as well as in hernia surgery.

Colon-cancer surgeries require what the doctors call anastomosis, removal of diseased intestine and reattachment to restore the gastronintestinal tract's functionality. The further down in the colon a surgeon must work, the higher the risk that a seal will leak, Sturlesi says. In some 15% to 25% of lower-colon operations, the seals leak, exposing the patients to infection and additional surgery, even death.

In such procedures, after a surgeon applies staples to close the colon, he or she spreads LifeSeal – using a glue-like applicator – along the line of the closure. The sealant provides a secure and elastic barrier to infection while the body heals. Tissue grows in and the sealant gradually dissipates.

LifeBond's second current major application, which the company calls LifeMesh, targets another very common surgery: hernias, the breaks in people's abdominal walls.

To secure a protruding intestine back into the abdomen, surgeons usually tack a mesh into place to close the break. These tacks cause inflammation and pain.

Here, the same proprietary material used in LifeSeal becomes an adhesive. In both open hernia surgery and procedures with a laparascope, the surgeon coats a standard mesh patch with LifeSeal and places it to secure the abdominal wall. The surgeon can reposition the mesh if and when necessary. LifeBond says the product keeps the patch in place as the body's tissues grow in and then dissipates.

LifeBond's two co-founders are Preiss-Bloom, 32, a New Yorker who is chief technology officer; and Ishay Attar, 42, who was vice president of business development at what is now Trendlines Medical, a tech-firm incubator. Both have master's degrees in biomedical engineering from the Technion, the Israel Institute of Technology. Attar remains a shareholder but doesn't hold a position with LifeBond.

CEO Sturlesi, 53, joined the company two years ago. Previously he was executive vice president at Lumenis, the producer of laser equipment for medical and cosmetic applications, and he was a co-founder of Galil Medical, a producer of cryosurgical technology. LifeBond's chairman is Ittai Harel, general partner of Pitango, a Herzliya, Israel, venture-capital firm and investor in LifeBond.

Worldwide market: $450 mln

LifeBond's first two target markets are substantial. The company estimates that annually in the U.S., 300,000 colorectal anastomosis procedures are done each year. The company pegs the worldwide market for this application at $450 million, a third of it in the U.S. And LifeBond says 2 million hernia repairs are done annually worldwide, half of them in the U.S. That's overall also a $450 million market.

LifeBond's investors include the Israeli venture-capital firms Aurum, Giza and Pitango. Also an investor, and a director, is Robert Taub, who founded Omrix, a producer of sealant used to control bleeding during surgery. J&J acquired Omrix in 2007.

In 2011, when LifeBond raised $20 million in a third-round financing, the New Brunswick, N.J., health-care giant J&J joined the round. Its specific investment hasn't been disclosed. LifeBond previously raised $1.5 million and $8.5 million in its Series A and Series B rounds respectively.

LifeBond is now in a Series D round, aiming to raise a total of $25 million by early 2015, and current investors have committed about half that figure.

In first-half 2013, LifeBond did a first clinical study in Sweden to test the application method for LifeSeal and to evaluate the product for safety. That study met its goals and this year LifeBond enrolled patients in a second study at eight centers in Belgium, Israel and Sweden. The company is expecting the results of that trial in November. The study's goal is to receive the CE Mark, which means that the product meets EU standards.

Sturlesi says the company has started the U.S. Food and Drug Administration process to develop the studies it needs to gain clearance to market LifeSeal in the U.S.

The company sees additional applications for LifeBond's system in surgeries involving the eye, brain, lungs, spine, urological system, and ear, nose and throat.

"We are there to support the natural healing process of the body," Sturlesi says.

Synthetic platelets helps clot blood faster

New York: Taking a cue from the human body’s own blood-clotting process, researchers at University of California, Santa Barbara have developed synthetic platelets that can do more than clot blood.
By creating nanoparticles that mimic the shape, flexibility and surface biology of the body’s own platelets, the team was able to accelerate natural healing processes while opening the door to therapies and treatments that can be customised to specific patient needs.
“This is a significant milestone in the development of synthetic platelets, as well as in targeted drug delivery,” said Samir Mitragotri, director of Center for Bioengineering (CBE) who specialises in targeted therapy technologies.
In case of blood loss due to minor injury, platelets release chemicals that “call” other platelets to the site, eventually plugging the wound.
But what happens when the injury is too severe or the patient is on anti-coagulation medication or is otherwise impaired in his or her ability to form a clot, even for a modest or minor injury?
That’s where platelet-like nanoparticles (PLNs) come in.
“These tiny, platelet-shaped particles that behave just like their human counterparts can be added to the blood flow to supply or augment the patient’s own natural platelet supply, stemming the flow of blood and initiating the healing process,” researchers emphasised.
“We were actually able to render a 65 percent decrease in bleeding time compared to no treatment,” said graduate student researcher Aaron Anselmo, lead author of the study.
With PLNs, emergency situations can be brought under control faster, injuries can heal more quickly and patients can recover with fewer complications, he added.
The results appeared in the journal ACS Nano.
