Hi PensionAlterEgo, Thank you for making the effort to post the information for all. It will definitely help us to appreciate the issue more. I now have more confident on BIG. With such low price now, I regreted for 'firing' all my bullets during the early days of mkt down trend. I should have preserve my ammo for the great 'killing' !

Part 2

Intimal hyperplasia

Hyperplasia is a general term referring to the proliferation of cells within an organ or tissue [7]. Hyperplasia may result in the gross enlargement of an organ or the formation of a benign tumor.



Figure 4. Arterial wall. Image taken from [1].

Figure 4 shows the make up of the arterial wall. The Tunica Intima (or just Intima) is the innermost layer of an artery. It is made up of one layer of endothelial cells (cells to reduce friction between artery wall and blood) and is supported by an internal elastic lamina. The endothelial cells are in direct contact with the blood flow. Intimal hyperplasia is started by damage to the vascular wall during angioplasty and may, in fact, be exacerbated by the metal stents [6]. Damage to the vascular wall results in endothelial erosion, triggering a process of thrombosis (blood clot) and leading to smooth muscle cell migration and proliferation at the site of injury. Immune cells also infiltrate into the site of the wound and promotes cell proliferation. Neointimal proliferation (access growth) is positively associated with deeper medial penetration of stent struts (see Figure 4) [6]. The deeper the stent cuts into the Tunica Intima and Tunica Media, the worse it is. Medial disruption and plaque fracture by stent struts is associated with greater numbers of inflammatory cells.

Measuring restenosis

There are many parameters that are used to measure or gauge the efficacy of a drug eluting stent with regards to restenosis. In some trial results, we often see a term known as Angiographic binary restenosis (ABR). It is basically the percentage of patients with a follow-up percent diameter stenosis of greater or equal to 50% determined by quantitative coronary angioplasty. Figure 5 explains the blockage clearer.



Figure 5. Coronary Stenosis. Image taken from [8]

In the first artery, the blockage is 50% in diameter or it simply means that 75% of the lumen (blood flow) area is blocked. When this happens a patient will contribute to the binary restenosis score in the DES trials. A severe case of restenosis or severe late lumen loss would lead to the need for revascularization.

Revascularization is the process of restoring the functionality of an affected organ; in this case the artery. We often see another term TLR, used in DES clinical trials. Target lesion revascularization (TLR) is defined as any repeat revascularization procedure (percutaneous or surgical) of the original target lesion site, which includes the stented plus edge (typically 5 mm away from each side of the stent) segments [4]. My interpretation of percutaneous is the repeat process of balloon angioplasty within the previously stented area. Surgical revascularization is basically a Coronary artery bypass graft (CABG). I am not sure if a repeat procedure of stenting over the old lesion is normally done and considered as revascularization. At the moment, I cannot find any document to support this fact.

Another often seen measurement of restenosis is late lumen loss. But this is not the best surrogate (substitute) endpoint for restenosis. Late lumen loss as a surrogate (substitute) endpoint for restenosis is used in DES trials because it significantly reduces the number of patients that need to be recruited [9]. Note that target lesion revascularization TLR is the most relevant endpoint to physicians and most importantly, to patients. Physicians are primarily concerned with whether the patients are going to come back with recurrent symptoms. By definition, TLR is what ultimately brings the patient back and not the measure of lumen loss [9]. This makes sense since lumen loss only given an indication how much growth has occurred. It has a weak correlation to TLR and is sometimes use to predict the number of revascularization that needs to be done. Therefore, clinical outcome, particularly target lesion revascularization (TLR), is regarded as the true measure of success for anti-restenosis therapies [9].

The following section provides a glossary of terms that are often found in DES clinical trial reports.

Glossary of vascular terms [10]

 

Angiographic binary restenosis (ABR)–Percentage of patients with a follow-up percent diameter stenosis of greater or equal to 50%. See Figure 5 above.

Angioplasty–A procedure used to unblock an artery clogged with plaque; also known as percutaneous transluminal coronary angioplasty (PTCA), or balloon angioplasty.

Coronary artery–An artery of the heart that supplies oxygenated blood.

Coronary artery bypass graft (CABG)–An invasive medical procedure in which a section of an artery from another portion of the body is used to bypass a blockage in a coronary artery to improve blood flow to the heart.

De novo–New, untreated; In trial reports, de novo simply means a coronary artery that has not been previously treated.

Dual antiplatelet therapy–The combination of aspirin and a second anticlotting medication such as clopidogrel (also called Plavix®) to reduce the risk of blood clots following stent implantation.

 

Endothelialization–Following stent implantation, the healing process of tissue regrowth over the stent to prevent thrombosis.

 

In-segment–A measurement of the length of a deployed stent plus 5 millimeters on either side of the stent.

 

In-stent–A measurement of the length of the deployed stent.

 

Late loss–The difference in measurements of a blood vessel lumen diameter before and after a stent procedure, as shown with angiography.

 

Late stent thrombosis–A blood clot that forms on the stent 30 days to 1 year post-implant.

 

Lesion–A blockage in a blood vessel that is interrupting blood flow to the heart, often due to plaque

 

Lumen–The cavity or hollow space inside a blood vessel.

 

Major adverse cardiac events (MACE)–Clinical events following a stent procedure that include death, myocardial infarction (heart attack), emergent CABG (bypass) and target lesion revascularization. Note that as long as any of these 4 clinical events appear, it contributes to the MACE rate/numbers. 

 

Neointimal hyperplasia–A medical term indicating the abnormal growth of new tissue over a stent.

 

Percutaneous coronary intervention (PCI)–A minimally invasive procedure to treat narrowed arteries. Commonly known as coronary angioplasty or simply angioplasty. The term balloon angioplasty is commonly used to describe percutaneous coronary intervention, which describes the inflation of a balloon within the coronary artery to crush the plaque into the walls of the artery.

 

Restenosis–The renarrowing of an artery in the same location of a previous treatment; clinical restenosis is the manifestation of an ischemic event, usually in the form of recurrent angina (heart attack).

 

Revascularization–A procedure to unblock or bypass a clogged artery. My interpretation is that plain balloon angioplasty is probably one of the revascularization methods used over the previously stented area. Bypass is another method. Note that, I am not sure if re-stenting over the old stent is normally done. At the moment, I am not able to say if this is a revascularization method.    

 

Stent thrombosis–A blood clot that forms on the stent; categorized as early stent thrombosis (0–30 days post-implant), late stent thrombosis (30 days – 1 year post-implant) and very late stent thrombosis (more than 1 year post-implant).

 

Target lesion revascularization (TLR)–Any repeat percutaneous intervention of the target lesion or bypass surgery of the target lesion. Note that this includes balloon angioplasty and bypass done over the old lesion. TLR is a very important measurement for DES trials.   

 

Target vessel failure (TVF)–When a patient experiences death, myocardial infarction (heart attack), emergent CABG, revascularization in the target lesion (TLR) or revascularization in the target vessel, which was previously stented, then this event contributes to the TVF value. TVF is basically the combination of 4 events of MACE plus the single event of TVR. If the 5 events above happen due to another vessel, it does not contribute to the TVF value.  

 

Target vessel revascularization (TVR)–Revascularization needed when a patient experiences a recurrence of symptoms and the lesion is somewhere along the length of the previous vessel treated. Note that this is a measure of revascularization in the same vessel but not in the previously stented segment. If revascularization happens on the previous lesion, this is TLR.    

 

Thrombosis–The formation of blood clots in arteries that can lead to myocardial infarction or death.

 


Very late stent thrombosis–A blood clot that forms on the stent 1 year or more post-implant.

Hi all, the following is a document that I tried to put together so that fellow forumers will be able to understand some of these mind boggling terms that we often see in clinical trial reports. With this, I hope that more forumers will be able to understand and appreciate the superiority of BIG's Biomatrix stents. Thanks to bengster for providing some initial comments and suggestions for changes. I am not sure if this forum allows me to post a long document.. so I am going to split into several parts.

Part 1. 

Disclaimer:

I am not medically trained and the information provided in this document is not a medical advice. The concepts and points collected herein could have been misinterpreted by me. Readers are encouraged to obtain the help, services and recommendations of doctors and other licensed medical practitioners. The purpose of this document is to facilitate dissemination of information about how to interpret drug eluting stent trial results. The images, text and contents contained in this document are for informational purposes only and not intended to substitute for the medical advice of a qualified physician, therapist or other trained professional. The contents of this document have been mostly borrowed from many different sources.

Stenting Process

Figure 1. Stenting process. Image borrowed from [1].

 

Figure 1 describes the stenting process in the coronary artery with plaque buildup [1]. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood [2]. The coronary artery is located on the surface of the heart. Figure 1A shows the deflated balloon catheter (also a process of angioplasty) and closed stent inserted into the narrowed coronary artery. The insert image on figure 1A shows a cross-section of the artery with the inserted balloon catheter and closed stent. In figure 1B, the balloon is inflated, expanding the stent and compressing the plaque to restore the size of the artery. Figure 1C shows normal blood flow restored in the stent-widened artery. The insert image on figure 1C shows a cross-section of the compressed plaque and stent-widened artery. When the plaque is compressed and the stent is expanded, the walls of the artery will naturally get damaged.

 

Restenosis

A common problem after angioplasty is too much tissue growth within the treated portion of the artery. This can cause the artery to narrow or close again, which is called restenosis. This problem is often avoided with the use of newer stents coated with medicines that help prevent too much tissue growth [1].

Figure 2. Restenosis of a Stent-Widened Coronary Artery. Image from [1]

The illustration in Figure 2 shows the restenosis of a stent-widened coronary artery. The coronary artery is located on the surface of the heart. In figure 2A, the expanded stent compresses plaque, allowing normal blood flow. The inset image on figure 2A shows a cross-section of the compressed plaque and stent-widened artery. In figure 2B, over time, the plaque grows through and around the stent, causing a partial blockage and abnormal blood flow. The inset image on figure 2B shows a cross-section of the growth of the plaque around the stent. Note that in this example, the plaque is shown as the cause of the re-narrowing or stenosis (abnormal narrowing in a blood vessel [3]). Stenosis can be caused by other means as well. An important one is the inflammatory response, which induces tissue proliferation around an angioplasty site (see Neointima Proliferation or Intimal Hyperplasia below) [3]. An analogy for this is some scarring on your skin that might sometime protrude out when you get a deep cut. In Figure 2B, the restenosis occurring inside the stent section is termed as “in-stent” restenosis. The restenosis inside plus 5 mm just outside the stent on both sides of the stent is known as “in-segment” restenosis.

Mechanism of In-Stent Restenosis

The mechanism/manifestation of restenosis can be explained by the lumen loss due to the process of angioplasty. Lumen loss is the difference in millimeters between the diameter of a stented segment post-procedure and at any time of interest [4]. Or putting it in simple terms, mean the loss of the blood vessel flow area due to the in-growth. Note that in most trials, late lumen loss is tabulated to give an idea of how much growth has occurred (thickness in millimeter). Figure 3 shows the artery cross section over a period of time when stenting (stent + balloon angioplasty) and plain balloon angioplasty is done.

Figure 3. Lumen losses. Image taken from [5]

From Figure 3 above, when balloon angioplasty is carried out, early lumen loss (within 1 hour of the procedure) is attributed to elastic recoil. This of course is not present in the stenting process because the stent acts as a scaffolding to prevent the recoil. Stents also reduces the impact of negative remodeling on lumen area when compared to plain balloon angioplasty [6].

 



 

Two mechanisms contribute to late lumen loss in patients undergoing Angioplasty are negative remodeling and intimal hyperplasia (indicated as Neointima formation in Figure 3). Note that in this example, the intimal hyperplasia is due to abnormal tissue growth and not plaque. Intimal hyperplasia remains a problem in stenting as well as plain balloon angioplasty.

BIG also has a BiolimusA9 ABSORB fully bioabsorbable DES using 100% PLA biodegradable polymer. So this technology is not new. Abbott also has their Everolimus ABSORB DES as well. Many people are already ahead of Freedy Boey. If BIG had their CE mark in 2006, BIG would have the cash to intensify R&D and clinical trial for their own BiolimusA9 ABSORB DES and perhaps can obtain its CE Mark in 2009. Abbott is expected to obtained their ABSORB DES CE approval somewhere in 2009 or 2010. I feel this absorb/soluble DES technology is rather "questionable" and may not work well.

Hi Bengster,

Thanks for the insights. Actually, was never worried about the funds Prof Freddy Boey is getting. Rather, its seems that this soluble stent business is generating much interest not only by the commercial but also the state. Why else would they throw $10m into the research if there is no value??

To me, all the more it seems that BIG is moving in the right direction. The more interest (positive of course) generated, the better and easier for BIG to promote their products.

***Victory89: Firstly, congrats to Prof Freddy Boey for getting the NRF funds..

Actually, I kind of know his story a little bit. He tried to sell his stent invention to a few companies (travelled to a Europe & US etc.. ) but there were no takers.. but eventually got Bio One (EDB linked) to pump in money to start up Amaranth Medical.

I have seen Freddy Boey's presentation before.. Looks impressive but very very far from commecialization. What do you expect.. he is a Materials guy.. not a MD or a biomed.

Has patents filed for stents, the earliest in 2005 but not granted yet.. and it mostly covers the stent design (mostly materials aspects). So has a long way to learn the ropes.. about true DES designs.

Last trial done on animals was around 2006. Since 2006, there was talk about human trials. Up till now, no human trials yet..

So make your own conclusion about this news..

***Bengster: There are many wild claims of revolutionary DES that has potential but until these companies can come out with a solid set of human clinical trial reports, all are baseless claims. This stent will take at least 5 more years to get commercialisation approval.

If Prof Freddy Boey is just a "Materials Engineer", then he has a lot more to learn about making a good DES. The stent design engineering, biomed knowledge, pharmaceutical knowledge, chemical knowledge and many other fields of knowledge are required and carefully formulated to make a good DES. This company now only has an "Angel" investor Bio One (EDB). Remeber the strongest point of a DES is the weakest link that is holding all the complicated DES composition parts together. One single weak area can cause the whole stent program to fail even if they score full marks for the rest of the composition parts. This new stent foetus has not even past its first-trimester pregnancy.

Sorry Not sure if it came out. Repost as below.

Research on soluble heart stents get $10m boost

A NANYANG Technological University (NTU) professor hopes to be testing soluble stents on heart patients here within two years.

Professor Freddy Boey just got a $10 million leg-up for his work.

His is among four promising research teams here which have been awarded up to $10 million apiece over three to five years by the National Research Foundation (NRF).

Three of the teams are from NTU, and the fourth, from the National University of Singapore.

Prof Boey, who has been working on the stent for five years , said: 'This award is recognition of the work we do.'

Stents used now are tiny metal wire-mesh tubes, sometimes coated with drugs, which are inserted into the blood vessels to keep them open and the blood flowing, to prevent a heart attack.

The one he and his team are developing is considered the holy grail of stents because it dissolves completely over time and releases drugs or proteins to prevent side-effects such as blood clots. Because no foreign body remains in the vessel, it can heal faster, cutting the risk of it becoming clogged over the next few years.

Section 5: Industry trends

Sustained investment interest in stents.

20 venture capital deals announced by companies developing stents or

stent-related products, totaling about US$320m. In Apr 08, two more deals

were announced with IDev Technologies raising US$25m and Tryton Medical

raising US$14m to further bring their stent technologies closer to market.

In Dec 07, REVA Medical raised US$42m from a bevy of high profile

investors, including Cerberus Capital and Medtronic.Since 2003, there have been

Easing regulatory restrictions in UK.

agency that governs medical device usage in the UK, National Institute for

Health and Clinical Excellence (NICE), issued a statement on a possible

withdrawal on DES from its state health system due to the lack of data

supporting its benefits vs. its higher costs. However, in Feb 08, these fears

were alleviated when NICE issued a new statement endorsing the use of

DES as long as it is not more than £300 than a BMS. UK government data

has indicated that the average DES price is about £529 vs. £131 for BMS.

For Biosensors, we think that it will be able to offer a competitively priced

product to meet this requirement due to lower cost base of production in

be seen from VHA’s Goodroe data, the utilisation of DES in stenting cases

this is US data, we deem that the Rest of the World will mimic this trend

Confusion in the midst of COURAGE.

looked at 2,287 heart patients who suffer from chest pain (angina) but who

are otherwise considered low-risk for heart attack, and concluded that the

addition of stenting to optimal drug therapy resulted in no significant reduction

in heart attack or death. This set off a media firestorm of misinterpretation,

causing confusion for patients and physicians. We found a balanced

interpretation of the COURAGE trials and present it here in our report:

1. The five-year COURAGE study,Can angioplasty and stenting save lives? In the case of a heart attack,

angioplasty definitely saves lives

COURAGE trial does not apply to patients who are having a heart attack;

Coronary Syndrome) — angioplasty and stenting have been proven to be a

not revolutionary, but instead are consistent with current practice guidelines

from all major professional groups (AHA/ACC/SCAI) that recommend using

angioplasty and stenting only after medical therapy has proven inadequate;

stents in these patients are not intended to prevent death, but to relieve

pain and improve quality of life.

8.

chronic condition — lifestyle changes, medications, stents are ways of

managing the disease and relieving symptoms, but they do not “cure” the

disease;

9. Did all the patients in this study experience relief of chest pain?

No. In the COURAGE study neither therapy completely eliminated angina

for more than a quarter of the patients. This maybe due to the fact that the

COURAGE patients with stents had Bare Metal Stents (BMS) which may

have a higher rate of restenosis.

10. Have patients with stable angina been given stents unnecessarily?

Under current practice guidelines, it is recommended that patients with stable

angina first be given a trial of medical therapy, along with lifestyle changes

and risk factor reduction. They are candidates for stents if they continue to

experience problems. What is unknown is how often these guidelines have

not been followed, and whether cardiologists have in fact recommended

stents as a first treatment option for this patient population. There is significant

controversy as to how often this occurs. Estimates of how many angioplasty

procedures are done in patients with stable coronary artery disease range

from 25% to 85%.

The high-end segment is dominated by a few large MNCs, while the lowend

companies. In terms of market value, the high-end occupies only about

10% to 20% of the market while the other 80% to 90% is still predominantly

filled by cheap medical devices with minimal advanced technologies.

However, market growth is nearly twice as high in the high-end market

(about 20% YoY) compared to the low-end. As a result, it is usually the

J&J's Cordis president leaving company
CHICAGO, June 13 (Reuters) - Johnson & Johnson (JNJ.N: Quote, Profile, Research, Stock Buzz) on Friday said the worldwide president of its Cordis unit is leaving the company on July 11, the latest in a string of departures of senior executives from the vascular device maker.

No replacement has been named for Todd Pope, who had been with Cordis for less than two years.

Others departures include Company Group Chairman of Cordis Rick Anderson; Chief Medical Officer Dr. David Kandzari; vice president of sales Mark Valentine; the vice president of health economics, Brian Firth and his replacement, Liesl Cooper; and the vice president of clinical affairs, Denis Donohoe, who will leave this summer.

Cordis makes such devices as catheters and stents.

"Although expectations among investors for Cordis' stent franchise are low, we view these significant changes at Cordis as an underappreciated near-term risk for Cordis' business and a potential opportunity for its competitors, Abbott Laboratories (ABT.N: Quote, Profile, Research, Stock Buzz), Medtronic Inc (MDT.N: Quote, Profile, Research, Stock Buzz) and Boston Scientific Corp (BSX.N: Quote, Profile, Research, Stock Buzz) to capitalize on," said Wachovia analyst Larry Biegelsen said in a research note.

Biegelsen said he has heard that turnover in the sales force has also been high . A Cordis spokesman declined to comment.

*** The top executives head rolled. Sales staff left also because they all already know NEVO will never work and this Cordis ship is sinking like Titanic. Only the C.T.O and conman Conor CEO Frank Litvack is still around fanning smoke for the NEVO DES smoke screen.

Article date: 27/03/2008 on JNJ's RES-ELTION 1 clinical trial to be used for CE submission

A randomized clinical trial comparing the Conor Sirolimus-eluting Coronary Stent, a new cobalt chromium reservoir-base stent design, to the Taxus Liberte Paclitaxel-eluting Coronary Stent has begun according to Conor Medsystems, LLC and Cordis Corporation, the sponsors of the study.

"We are pleased that the RES-ELUTION trial has begun and that the first patient enrolled in this study occurred at our hospital. The product was easily delivered and performed well," said John Ormiston, M.D., North Shore Hospital, Auckland, New Zealand and Principal Investigator for this study. "The potential of sirolimus delivery from a fully-bioresorbable reservoir is exciting and may represent a breakthrough in the interventional treatment of patients with coronary artery disease."

The RES-ELUTION study is a randomized, multi-center comparison of the Conor Stent to the Taxus Liberte Stent in de Novo native coronary artery lesions. The primary endpoint of the study is angiographic in-stent late lumen loss at six months. The Conor Stent contains the same drug, sirolimus, as in the CYPHER® Sirolimus-eluting Coronary Stent, which is marketed by Cordis Corporation.

Secondary endpoints include target lesion failure, target vessel failure, major adverse cardiac events (MACE), stent thrombosis, target lesion revascularization, target vessel revascularization, and angiographic in-stent and in-segment binary restenosis at six months. Up to 50 patients will also be evaluated via intravascular ultrasound (IVUS) at six months.

The study will involve 388 patients at 40 sites worldwide including Australia, Belgium, Brazil, Denmark, France, Germany, New Zealand, The Netherlands and the United Kingdom. Patients will receive clinical follow-up at 30 days, six months and annually through five years.

Data from this trial will support a regulatory filing for a CE mark in countries outside the United States.

The unique Conor Medsystems technology is an important 'next generation' technology design that incorporates hundreds of small reservoirs, each acting as a depot into which drug-polymer compositions are loaded. This breakthrough design greatly enhances control of the rate and direction of drug delivery, enables a wider range of drug therapies, and potentially increases the range of clinical applications of drug-eluting stents and other drug-device combinations.

About Conor Medsystems, LLC

Conor Medsystems, LLC, a wholly-owned subsidiary of Johnson & Johnson, develops innovative controlled vascular drug delivery technologies, and has primarily focused on the development of drug-eluting stents to treat coronary artery disease.

About Cordis Corporation

Cordis Corporation, a Johnson & Johnson company, is a worldwide leader in the development and manufacture of interventional vascular technology. Through the company's innovation, research and development, Cordis partners with interventional cardiologists worldwide to treat millions of patients who suffer from vascular disease.


*** I expect 6 months later NEVO DES will flop like all the other Costar trials and JNJ got no more NEVO show left. LEADERS results will be out by then.

Bollinger bands are really tight now. Large price change may occur.


The last time this happened, there was a upwards spike in price. However, at that time, the Acc/Dist chart was uptrending (a bullish sign).

But this time, there is no such signal.

I am back !!!! shit... yesterday landing at 6.20 am is the worst experience I have ever... it is raining, and thunder light can be seen every 10 seconds, but with our prestiguous SIA pilot, he is able to land perfectly... without any "twist and turns" on the runway... 2 thumbs up for SIA pilot.... 

Yupe the price can be disappointing, but from the 0.69 entry point of view, I think it has done a good job to sustain the price, you have to judge across the market performance.. I am pleased so far..
