MOORE LABRIOLA LLP ATTORNEY THOMAS MOORE ADDRESSES FDA OPHTHALMIC DEVICES PANEL ON THE HUMAN TOLL OF ACANTHAMOEBA KERATITIS RELATED TO RECALLED CONTACT LENS SOLUTIONS
On June 11, 2008, the Food & Drug Administration’s Ophthalmic Devices Advisory Committee met to consider a number of issues related to the safety and effectiveness of contact lens care products. The meeting of the Committee, a panel of outside experts in optometry, ophthalmology and other fields, was convened by FDA in the wake of the recalls of two leading contact lens disinfectant solutions. Bausch & Lomb’s Renu ® with MositureLoc™ was recalled in 2006 after the product was linked to serious fungal infections. In May 2007, Advanced Medical Optics, Inc. recalled its Complete® MoisturePlus™ solution after reports reviewed by the Centers for Disease Control and Prevention found a strong association between use of the product and the development of Acanthamoeba keratitis, a site-threatening corneal infection cuased by infestation of a species of protazoa.
During the public comment segment of the FDA meeting on June 11, FDA officials and the Advisory Committee were addressed by Thomas M. Moore, co-founding partner of Moore Labriola LLP of Newport Beach, California. Moore, whose firm is currently acting as co-lead counsel in a large number of lawsuits brought against the manufacturers of recalled contact lens solutions, discussed the human toll caused by corneal infections associated with these products.
Following Moore’s comments and those of several medical and scientific experts, the Advisory Committee made a numerous recommendations to FDA concerning the future regulation of contact lens care products. The panel’s recommendations included more stringent pre-marketing testing requirements, including tests showing the effectiveness of contact lens solutions against Acanthamoeba, as well as more specific warnings and instructions on the labels of these products in order to increase consumer awareness of their proper use and their significant limitations in the control of infectious agents that commonly contaminate contact lenses.
The following is from the official FDA transcript of Mr. Moore’s comments made to the Ophthalmic Devices Advisory Committee on June 11:
“Good morning. My name is Thomas Moore, and here is my financial disclosure. My law firm currently represents a large number of Americans from across the country who contracted devastating corneal infections associated with their use of ineffective multi-purpose contact lens care solutions.
Every single one of my clients wishes that they could be here today. They have waited a long time to see critical public health issues surrounding contact lens care products taken up by FDA in what is a truly public forum with both industry and non-industry voices being heard.
I’m simply a messenger, probably an inadequate one, attempting to relate to you the thoughts and concerns of the many individuals whose lives have been forever changed by their use of this product, and the hopes that future infections can be reduced, or prevented entirely.
I can’t more aptly describe the latest outbreak of acanthamoeba infections as prominent ophthalmologist, Dwight Cavanagh, did recently when he called it a train wreck in slow motion. Indeed, the train started to wreck many years ago in the 1990s when multi-purpose solutions began to replace proven disinfection techniques, such as heat and hydrogen-peroxide systems.
My clients are hard pressed, as lay people, to understand why manufacturers designed multi-purpose solutions that relied on PHMB in concentrations that they knew full well were ineffective against acanthamoeba. My clients are understandably angered when they learn that FDA never required testing against acanthamoeba.
They also find the International Standardization Organization’s justification for omitting acanthamoeba as a challenge organism in efficacy testing as nothing less than bizarre. The ISO, an organization that at least appears to be largely controlled or influenced by industry, has consistently maintained that there is a lack of consensus as to how acanthamoeba testing should be conducted.
ISO and FDA have thus reasoned that such testing should not be required, even if it means that products ineffective against this devastating disease will be cleared for marketing.
The great irony is that at the same — the same manufacturers who lobbied against acanthamoeba testing as a regulatory hurdle nevertheless conducted, and in many cases published, the very tests that they said could not be done in a scientifically valid manner.
Paradoxically, some would say outrageously, manufacturers such as Advanced Medical Optics and others, are even now using such internal testing as the basis for advertising claims that their current PHMB-based products provide enhanced effectiveness against acanthamoeba strains.
If the testing is valid, it should have been required as a regulatory matter. If it isn’t, it should not be allowed as a basis for marketing claims. It’s as simple as that.
In 1998, one of your colleagues, Debra Schonberg, and her colleagues were prescient in their article entitled “The Epidemic of Acanthamoeba Keratitis: Where Do We Stand?” When they opined that the risk of acanthamoeba keratitis was likely underestimated, even after the 1980s outbreak, and that a major risk factor was, quote, the continued existence of ineffective lens disinfection systems, indeed, it was apparently known early in the marketing of PHMB-based solutions that these products showed great variability in their effectiveness against acanthamoeba trophozoites, and little or no effect against acanthamoeba cysts.
It should have, therefore, come as no surprise when starting in 2003, the same year that Complete Moisture Plus was launched in this country, ophthalmology centers started to see increasing cases of AK at their institutions.
These outbreaks, which were reported at numerous U.S. and international ophthalmology meetings, should have been a wake-up call, but several years later, and after two major lens solution recalls, testing and labeling standards have not changed.
My clients wholeheartedly applaud FDA for convening this meeting. However, I must tell you that there is an element of mistrust as to the motives and objectives of FDA and the contact lens branch, in particular. This has largely emanated from a lack of transparency on the part of FDA insofar as the general public is concerned.
It is a perception based partly on statements by industry and FDA officials that at least appear to place much of the blame for these infections on so-called consumer noncompliance, as opposed to the lack of solution efficacy.
I will tell, you ladies and gentlemen, that the vast majority of my many clients were very diligent in their use and care of contact lenses. They did not sleep in their lenses, or reuse or top off solutions, or rinse their cases with tap water. Some rubbed, and some didn’t. And on that score, they weren’t any more confused by AMO’s no rub marketing claims than their optometrists were.
The minority who AMO and others would likely consider as noncompliant patients wonder why a company would market a solution with such a slim margin of safety, and without any indication on the label of the risk of acanthamoeba infections.
In addition to feeling that they are being blamed for their infections, my clients are concerned that industry’s role on these outbreaks has not been sufficiently scrutinized in a fair, objective, and public forum, while FDA maintains a close working relationship with manufacturers.
It has been unwilling, until today, to allow the public access to important data about these products, or a voice in the debate on these critical public health issues.
By way of example, my clients made a series of Freedom of Information Act requests over a year ago seeking access to documents concerning the evolution of testing standards, the clearance of the AMO Complete Moisture Plus product for marketing, and events leading up to the recall of that product.
Most of these requests have not been complied with. An appeal by my clients to the Department of Health and Human Services designed to expedite access to these materials was denied on the grounds that there was, quote, no showing of an immediate threat to the public health.
In addition, FDA has, at least thus far, deemed confidential all briefing documents submitted by it and the solution manufacturers to this Advisory Committee. Perhaps that will change in the coming days.
FDA’s conduct in this regard is inconsistent with my long experience in dealing with other divisions and branches. Similar information, including safety and efficacy data in new drug applications, for example, is routinely furnished to the public by the drug branches in a timely manner, and with few redactions.
So there is no question in my mind that FDA has the discretion to release these records, and I hope they will do so soon. Inevitably, a lack of transparency necessarily leads to rumors. The notion that FDA has delayed changes to testing standards because most marketed multi-purpose solutions would not pass those tests is a common perception; that FDA delayed calling this Committee meeting for months or years at the request of manufacturers is another.
Still another is that FDA and CDC disagreed vehemently with each other as to whether the recall of the AMO product should be voluntary or subject to FDA Class I Recall Protocols. Now, these perceptions may be accurate or inaccurate. But without transparency in the regulation of the contact lens care products industry, victims of corneal infections related to solutions may see the Agency’s relationship with industry as collusive, rather than cooperative.
FDA often talks in terms of acting in the interest of stakeholders. We should all hope that FDA considers its most important stakeholders to be consumers who use the products the Agency regulates.
There is an enormous opportunity that presents itself today which goes far beyond politics, corporate profits, or lawsuit recoveries. There is an opportunity for FDA to change the direction of the contact lens care industry, and by so doing, make contact lens wear substantially safer for millions of Americans.
This can only be achieved by adding to the diversity of voices FDA listens to, starting with this Committee, and by instituting a transparent process in which testing and labeling issues are carefully considered, and resolved in a way that best protects the public health.
My clients and I thank you for this opportunity to speak, and simply ask that FDA and the Advisory Committee make the health of consumers their number one priority. Thank you.”
