What we'd like to do is give a very short statement at the beginning. We'd really like to use most of the time to give the committee members the opportunity to ask questions. Obviously we're here because of a motion that was passed for us to go over the decision that we made.
Mr. Chair, members of the committee, I wish to thank you for the opportunity to appear before you today to provide information regarding Health Canada's regulatory review and subsequent licensing with conditions of silicone gel-filled breast implants under the medical devices regulations and the Food and Drugs Act.
I have with me today my colleague Mary-Jane Bell, who is the head of the musculoskeletal section of the medical devices bureau of the therapeutic products directorate. She has considerable experience on this file; she has actually been working on it since 1991.
l'd like to begin by briefly outlining both the comprehensive review of these products as well as the significant steps that have been taken to openly share the results of the review with the Canadian public. Following that, we welcome this opportunity to answer any questions committee members may have with respect to the rigorous review that was conducted.
On October 20, 2006, Health Canada announced the decision to grant licences with conditions to Inamed Corporation and Mentor Medical Systems to allow them to sell silicone gel-filled breast implants in Canada. The decision allowed women seeking breast reconstruction following a mastectomy and those seeking breast augmentation open access to silicone gel-filled breast implants.
In order to reach its decision, Health Canada engaged in a four-year-long review, examining more than 65,000 pages of information submitted by the manufacturers. In addition, Health Canada also reviewed the relevant medical and scientific literature, the report of the Expert Advisory Panel on Breast Implants, and submissions from interest groups and interested persons as part of the review. It is significant to note that the directly related scientific and medical literature alone consisted of well over 2,500 articles, with over 6,000 articles in total being examined.
As you are aware, breast implants, both saline and silicone gel-filled, are regulated as medical devices in Canada. The regulatory framework that governs the importation, sale, and advertisement of medical devices has been established by Parliament in the form of the Food and Drugs Act and the medical devices regulations.
The licensing of these products signifies that they have met criteria for safety, effectiveness, and quality, and have undergone an independent, impartial, and objective analysis of scientific evidence. The scientific and regulatory basis for the decisions included assessment of such criteria as manufacturing and quality control; preclinical studies, including chemical, physical, and biocompatibility tests; clinical effectiveness and safety; and labelling of the devices, which includes the patient brochure.
The results of the review have been compiled in the form of the summary basis of decision documents, which describe the type of information provided and what was considered during the licence applications review process. These documents have been made publicly available on the Health Canada website.
In order to ensure that the medical devices licensed continue to meet safety and effectiveness standards, Health Canada, through a combination of conditions and commitments, has required the manufacturers to produce annual reports through to 10 years for clinical studies under way outlining complications and patient/physician satisfaction measures.
We've asked them to conduct at least two patient focus groups in Canada to determine the effectiveness of device labelling. A report on these sessions, along with analysis and recommendations for labelling changes, will be submitted to Health Canada within a year of licensing.
We've required the manufacturers to conduct a large long-term appropriate post-approval study, involving tens of thousands of women. The study will include Canadian women and will be designed to measure any previously undiscovered connection between the use of silicone gel-filled breast implants and any potential rare events. Manufacturers are required to start the study within one year.
We've also required them to survey Canadian plastic surgeons who use the implants, to determine the effectiveness of the labelling and of the decision aids provided with the implants. A report on the survey is to be submitted to Health Canada within one year.
The last condition is that manufacturers continue implant retrieval and analysis studies, from all available sources, for further characterization of potential modes and causes of implant failure.
In addition to the conditions, manufacturers have committed to the following. They have agreed to provide Health Canada with updated marketing histories, including the number of units sold and a summary of any reported problems or recalls concerning the devices, in Canada and internationally.
They have also committed to provide implant registration cards with the devices so that patients receiving these cards from their surgeons can send them voluntarily to the manufacturer. This will allow the manufacturer, in addition to using general methods of dissemination, to distribute any new information directly to the persons affected.
As requested through the motion passed by the committee, we are in the process of providing the information that formed the basis of our decision. As you can well understand, given the volume and the technical nature of the information, this involves considerable human and financial resources.
In announcing the licensing decision, Health Canada continued, and continues, to remind Canadians that no medical device or drug is 100% safe, effective, or without risks. Under the regulations, reasonable measures must be taken to identify the risks associated with the device and to eliminate them or reduce them as much as possible.
The conditions that have been applied to these licences are intended to continually provide information to the patient and health care professional on the risks associated with these devices in order to allow for an informed decision process after the patient has consulted with a physician and has fully explored the risks and the benefits associated with the product.
In conclusion, it should be noted that silicone gel-filled breast implants are some of the most intensively studied medical devices in modern medical history. The decision to grant licences with conditions for these silicone gel-filled breast implants comes at the end of a rigorous scientific and clinical review.
It is also worth noting that more than 130 countries have already licensed these breast implants, including the most recent decision of the United States Food and Drug Administration, which announced the approval of these devices on Friday, November 17.
Finally, I'd like to thank you for inviting us to speak to you today. We welcome the opportunity to answer any questions you may have.
Thank you, Mr. Chair.
The FDA authorized breast implants last week on November 17. Health Canada also made its announcement on a Friday. Newspaper reporters were no longer on Parliament Hill, so they could not react immediately to the news.
I have in my possession documents from Inamed, a subsidiary of Allergan in the United States. We are talking about Inamed here, and you approved a license for that company. In a document entitled Directions for use, Inamed Silicone-Filled Breast Implants, it clearly states that people who receive breast implants must undergo magnetic resonance imaging at least every two years. Otherwise, the risk of rupture and leakage is very high. It also mentions other health problems. It says that a high number of ruptures are thought to be responsible for serious problems. In the United States, the FDA recommends that women who have had breast implants undergo magnetic resonance imaging at least once every two years.
In addition, Dianne Feinstein, a U.S. Senator, is opposed to the reintroduction of breast implants. Her arguments against them are the same as the arguments we put forward before. Inamed Corporation and Mentor Medical Systems are still facing allegations made by scientists and very credible individuals. Among others, Dr. Sidney Wolfe, Director of Public Citizen's Health Research Group, said that the approval makes a mockery of the legal standard that requires reasonable assurance of safety for drugs and prostheses. He said that, in the case of implants, the risk of rupture and leakage of silicone gel in patients' bodies was high and that they therefore pose health risks.
I have also received emails. For example, a young woman from Manitoba who received breast implants now has to have them removed because they ruptured. But she cannot have the operation because in order to get it quickly, she would have to spend $5,000 out of pocket. Otherwise, the waiting period is two years. The ruptured implants are causing her serious health problems.
You are authorizing companies like Mentor and Inamed to use women in Quebec and Canada as guinea pigs, women who are in good health now but who may not be in the future because of the decision you made. I wonder if you thought about that when you made the decision. In the past, thousands of women have had serious crises because of breast implants. Now, because you made a hasty decision, thousands of women will risk going through that again.
We know that Health Canada receives $42 million a year to approve the devices. Did that factor play into your decision? Can you really be neutral under those circumstances? I would like a list of the people who participated in making that decision, Ms. Bell.
:
Mr. Chair, a number of issues were raised, and I'll try to make sure we go through all of them.
I'd like to start with the last comment. With 100% certainty, I can say categorically that this review was independent, impartial, evidence-based, and scientific. If there is an insinuation that in any way, shape, or form there was undue influence on the review, nothing could be further from the truth.
To give you a little bit of context, a normal medical device review in terms of our performance targets takes 90 days on average. That's our maximum. A lot of them will take less than that. These products have been under review for four years. As I mentioned before, these are the most intensively studied medical devices in history, and as I said, none of them are without risks.
The idea of doing a review is to ask if these medical devices, under the regulatory framework under which we are working, made by parliamentarians, meet the safety, effectiveness, and quality standards that are outlined. Do we know what the risks are? If we could have minimized those risks, have we minimized them? Have we quantified those risks? Are we able to provide information to the Canadian public, so they can make informed decisions about their health?
I cannot underscore that more. It really is up to the patient and his or her practitioner to have that dialogue about the risks and benefits of any treatment. It's the same whether you are taking an aspirin or whether you are having silicone gel-filled breast implants. It depends on knowing what those risks and benefits are.
Because these products have been so intensively studied, we know the risks and benefits and we feel they have met the criteria of the Food and Drugs Act and regulations. Having said that, we wanted to make sure they continue to meet those standards, and that's why those post-market conditions were put in place.
In terms of the FDA decision, you'd have to go back to the FDA to decide why they announced it at the time they did. When we made our decision, we made sure we made the announcement in the morning to allow people to comment and for officials to be present on the Hill to brief anybody who wanted to be briefed. We made a conscious decision to make sure we did that early in the day.
On the subject of MRIs, the products are really well labelled for the decisions. We asked our expert advisory panel what their opinion was on the use of MRIs and they gave specific recommendations.
They did not feel MRI follow-up was the best way to follow them up, and that's clearly outlined in the labelling. So if you read the labelling for the products, it goes through the debate and it explains what the FDA opinion was. The FDA had conflicting opinions as well. They had one expert advisory panel recommend it every two years, and they had another expert panel that did not recommend it every two years.
So the recommendations now are to look for clinical signs and symptoms, to go for a mammogram, and to go for ultrasound, and if there is any suspicion, then to sit down with a physician and decide at that point.
If you are going for an MRI, there may be a wait for an MRI, so the decision might be to go and remove them. If not, you can wait for an MRI and do that. But we specifically asked the question on MRI. We've specifically received an expert opinion on it, and the recommendation was not to have an MRI follow-up every two years.
In terms of Public Citizen, that is a consumer advocacy group. In the United States they have a public petition process. Public Citizen has come before the FDA with their concerns and they've had their hearings, and the FDA have cleared all the issues they've had with Public Citizen.
Another part of the question was speaking to wait times for having implants removed. Again, if there is a health risk, if there is a health reason for them to be removed, it's a priority, but individual surgeons will be making their own decisions in terms of their own lists. If it is due to health, then the public health system covers it. If it is not due to health concerns, then it is not covered.
The practice of medicine is regulated at the provincial and territorial level. It's not regulated at the federal level and it's not under the jurisdiction of Health Canada.
:
That's a good question.
Actually, 65,000 only represents the number of pages submitted by the companies as part of their application. When you look at the total number of pages, all the scientific and technical articles, and the books that were included in that, it numbers in the hundreds of thousands of pages.
As you can imagine, there are a number of things that actually have to proceed before we provide those to committee, including translation, review for proprietary information, and verification. In terms of the papers, we have to get consent from any of the scientific writers. We have to get permission from them to translate.
The total cost of providing all the information that forms the basis of the decision would amount to--and this is a conservative estimate, because it doesn't actually include any delays to other ongoing medical device reviews--$55.9 million.

Thank you very much, Mr. Chair. I have one quick question and then I will yield the rest of my time to Madam Demers, who has spent a great deal of time on this issue. I know she's very passionate about this and I want to give her an ample amount of time to ask her questions.
First of all, thank you to the witnesses for appearing today.
My comment is, at least we have a decision. My frustration the last time this issue came before this committee was the fact that there really was no decision. We seemed to be in limbo.
I wonder if there could be some consideration given to developing some literature for patient education that could be distributed to family physicians nationwide. We talked in our study of childhood obesity about how GPs could be given information for their patients. The same thing could apply here.
Perhaps there could be a piece of literature put together that GPs could distribute to their patients, because the number of Canadian women who will actually see a label and read through all of the information will reflect a very low percentage. I think if we make it easier for Canadian physicians to pass on this scientific-based, non-biased information to their patients, then it would help Canadian women make that decision. I do think this is significantly different from the aspirin example. There's significant post-surveillance requirements here, much more so than any other device or drug that I'm aware of.
Since it's been studied for four years, I think it's a reasonable request. I wonder if you'd give it some consideration and take that back to Health Canada.
That's my question. The rest of my time will go to Madam Demers following the response.
Thank you, Mr. Chair.
:
Thank you for being so generous, Mr. Chair.
Thank you too, Mr. .
You said that you took into consideration the 65,000 pages provided by the industry, by Inamed Corporation and Mentor Medical Systems, before approving silicone gel-filled breast implants, also known as gummy bear implants. However, you also said that you consulted another expert to determine that magnetic resonance imaging was not necessary after two years.
Do you mean to say that the information contained in the 65,000 pages provided by Mentor Medical Systems and Inamed Corporation is unfounded? What I have here comes from those documents. In their own words, they say:
[English]
Therefore, you should advise your patient that she will need to have regular MRIs over her lifetime to screen for silent rupture, even if she is having no problems. The first MRI should be performed at three years post-operatively, then every two years thereafter.
[Translation]
We know that young women who have had MRIs within the past two years are not supposed to have access to silicone gel-filled implants for breast augmentation.
Will they still have access through the special access program for medical devices?
:
Thank you very much, and thanks for your report, Dr. Sharma and Dr. Bell.
I note that on page 3 you talk about your scientific and regulatory basis for decision-making in allowing these back on the market. Manufacturing and quality control--that's a good one. Preclinical studies--that's a good one. Biocompatibility tests, effectiveness and safety, and labelling are good ways of informing the patient about what is currently the status.
But given that this product is a product that has had very severe side effects in the past, I would see it not just as any other device on the market; I would see it as a red-flag device. I would have hoped--and I wonder why you didn't consider doing it--that for this particular product, there would be mandatory reporting by physicians of any new adverse effects, not at the end of the year but immediately, rather than on the voluntary basis by which they would be reporting those things. I just think, purely because this is a red-flag device and not just any old one, that we need to be able to do that, because I think we should still be putting this product on sort of a trial basis, so to speak, because it has to re-prove itself now.
I mean, it's about the fact that this is not merely something you wear on your arm. It's something that if it causes problems becomes an absolute horror to remove, and therefore the ability to look at the patient's long-term results, if something goes wrong, is extremely important. So you would need to know sooner rather than later, and at the early stages, that something is going wrong. So for that reason, I wondered why you did not decide to have mandatory reporting by physicians of any adverse effects.
As a physician, I don't believe in mandatory reporting. It's too much like hard work. If you had to do it on everything, you'd never practise medicine. But at the same time, because this is a specific red-flag device, I would have thought that it would be an important thing to do.
Second of all, in terms of the special access program, the special access program is very much an exception program. The reason we prefer to have products that have gone through the rigorous review is that we do have the ability to put conditions on them in terms of the licensure to be able to regulate them. For the special access program, there's limited monitoring because it's an exception program. But as a result of the special access program, we have not received any complaint reports submitted from the cohort of patients who have been examined.
In terms of the comparison, the comparison was not being made between risks associated with aspirin and risks associated with breast implants. What I'm saying is that something on a very low level of risk, such as an aspirin, still carries risk, as well as something on a high level of risk.
This is a surgically implanted device. There are risks to surgery. There are risks to putting a foreign body into your body. We know the risk. We've studied the risk. We've informed people of the risk. We've labelled the products. We've done an intensive review. So what I'm saying is that everything we do has a certain amount of risk associated with it, and we have to consider both the risks and benefits of anything we do in terms of our health care.
What we're doing is saying that these devices have passed the bar in terms of safety, effectiveness, and quality, and just to remind everyone again, that's mandated by the Food and Drugs Act and regulations, the medical devices regulations, put in place by Parliament, which forms the basis of our regulatory decisions. They've made that submission. Those submissions have been reviewed and they've met those criteria.
To continue to meet those criteria, there are conditions that are put on their sale. But all medical devices have risks associated with them. They are not 100% safe, they are not 100% effective, and we need to continue to monitor them. We need to know about the risks. We need to know about the benefits. Practitioners need to inform their patients. Patients need to inform themselves, and people need to make educated, informed decisions about their health.
