SMOKING LINKED TO VISION LOSS

Rate of Age-related Macular Degeneration Among Smokers Significantly Greater Than Non- Smokers

 COLUMBUS Age-related Macular Degeneration (AMD) is an eye disease that affects more than 1.65 million Americans over the age of 50.  AMD has no cure, although several new promising treatments are currently being tested that have shown promising results in halting the progression of the disease for some.

 Age-Related Macular Degeneration creates a loss of sharp central vision. There are two forms: wet and dry -which is the most common form. The exact cause of AMD is unknown. Currently, 71, 113 Ohioans have AMD. By the year 2030, 142, 226 will have AMD if nothing is done to curb its growth. Risk factors include: race (more common in Caucasian populations), smoking, obesity, gender (women are more likely to have AMD than men), and family history.

 Recent studies have shown that one way to reduce the risk of developing AMD is by not smoking.  A study published in the British Medical Journal from the University of Manchester found that smokers were three to four times more likely to develop AMD than non smokers.  And, non smokers living with smokers almost double their risk of developing AMD.

 Fortunately, the research also showed that former smokers who had quit for over 20 years had the same risk level of those who had never smoked.  Smoking impairs the effects of antioxidants, which then damage the retina. 

 In a recent survey commissioned by AMD Alliance International, only 32 percent of respondents who had heard of AMD were aware of the link between AMD and smoking.  In addition to AMD, smoking has been linked to increases in the cases of cataracts, glaucoma and diabetic retinopathy.  

 “We’ve all known for years that smoking is bad for our health,” said Sherill K. Williams, president and CEO of Prevent Blindness Ohio.  “But some people may not know that besides being a risk factor for cancer, heart disease and a host of other health problems,  smoking is also linked to vision loss.”

 Prevent Blindness Ohio has designated February as Age-related Macular Degeneration Awareness Month in an effort to educate the public on the disease and what steps can be taken to avoid it. “We also want to remind everyone, whether they are smokers or not, that the most effective way to fight the effects of AMD is through healthy lifestyles and regular, professional eye exams. ,” added Williams.

 Healthy habits can help preserve healthy eyes.  The risk of eye disease and vision loss can be lowered if you:

  • Don’t smoke
  • Eat healthy foods (including green leafy vegetables and foods high in zinc, vitamins C and E, and beta carotene)
  • Control blood pressure and cholesterol
  • Stay active
  • Visit your eye care professional on a regular basis

PRELIMINARY PHASE III DATA FROM HEAD-TO-HEAD STUDY OF LUCENTIS SHOWS LUCENTIS IMPROVED VISION Compared TO VISUDYNE IN PATIENTS WITH WET AGE-RELATED MACULAR DEGENERATION

-- Second Phase III Study to Show Lucentis Maintained or Improved Vision
in
Approximately 95 Percent of Patients at One Year --

New York -- January 14, 2006 -- Genentech, Inc. (NYSE: DNA) announced
today
positive one-year results from its second pivotal Phase III study of the
investigational drug Lucentis(tm) (ranibizumab) in patients with wet
age-related macular degeneration (AMD). Data from the ANCHOR study
comparing
Lucentis to verteporfin (Visudyne(r)) photodynamic therapy (PDT) showed
a
difference in mean change in visual acuity of 18 letters for patients
treated with 0.3 mg of Lucentis and 21 letters for patients treated with
0.5
mg of Lucentis from study entry compared to those treated with PDT at 12
months. In the first year of this two-year study, patients treated with
Lucentis gained an average of 8.5 letters in the 0.3 mg dose group and
11
letters in the 0.5 mg dose group compared to patients treated with PDT,
who
lost an average of 9.5 letters. In November 2005, Genentech announced
that
the Phase III ANCHOR study met its primary efficacy endpoint of
maintaining
vision (defined as a loss of less than 15 letters in visual acuity) in
patients with wet AMD. One-year data from the ANCHOR study were
presented
today during Macula 2006, a medical symposium held in New York and
sponsored
by the Manhattan Eye, Ear & Throat Hospital.

            "Lucentis is the first investigational therapy that has
shown
improved vision, not just a slowing of vision loss, in patients with all
types of wet AMD," said Peter K. Kaiser, M.D., director, Clinical
Research
Center, The Cleveland Clinic Cole Eye Institute, who presented the data
today. "As a result, physicians may be one step closer to being able to
set
a new expectation for the future treatment of this condition."

An analysis of the one-year data showed that adverse events were similar
to
those seen in earlier trials of Lucentis. Common ocular adverse side
effects
that occurred more frequently in the Lucentis arms than in the control
group
were mild to moderate and included conjuctival hemorrhage, increased
intraocular pressure, eye pain and vitreous floaters. Serious ocular
adverse
events that occurred more frequently in the Lucentis-treated arms were
uncommon and included endophthalmitis and intraocular inflammation (each
reported in less than 1 percent of patients per group). Among non-ocular
serious adverse events, the frequency of cerebral vascular events was
less
than 1 percent of patients per group. The frequency of myocardial
infarctions was slightly higher in patients treated with 0.5 mg of
Lucentis
(2.1 percent) than in the other two arms (0.7 percent).

Additional key clinically meaningful study findings include:

*       94 percent of patients (132/140) treated with 0.3 mg of Lucentis
and
96 percent (134/139) of those treated with 0.5 mg of Lucentis lost fewer
than 15 letters compared to baseline, the primary efficacy endpoint of
the
study, compared with 64 percent (92/143) of those treated with PDT
[p<0.0001].
*       Nearly 36 percent of patients (50/140) treated with 0.3 mg of
Lucentis and 40 percent of patients (56/139) treated with 0.5 mg of
Lucentis
improved vision by a gain of 15 letters or more compared with
approximately
6 percent of patients (8/143) treated with PDT.
*       31 percent of patients (44/140) treated with 0.3 mg of Lucentis
and
nearly 39 percent of patients (54/140) treated with 0.5 mg of Lucentis
achieved visual acuity of 20/40 or better at 12 months compared with
approximately 3 percent (4/143) of those treated with PDT.

"Through the extensive clinical study program for Lucentis we have now
shown
a significant improvement in vision compared to Visudyne and in patients
with all types of wet AMD," said Hal Barron, Genentech senior vice
president, Development and chief medical officer. "We look forward to
working with the FDA on our BLA submission and Priority Review request.
Given the existing unmet medical need for patients with wet AMD, we are
providing access to Lucentis for eligible patients through SAILOR, a
Phase
IIIb safety study."

In December 2005, Genentech announced that it had submitted a Biologics
License Application (BLA) to the U.S. Food and Drug Administration (FDA)
for
the use of Lucentis in the treatment of neovascular wet AMD. The BLA
submission, which included a request for Priority (six-month) Review, is
based on one-year clinical data on the efficacy and safety of Lucentis
from
two pivotal Phase III trials, ANCHOR and MARINA, as well as one-year
clinical data from the Phase I/II FOCUS trial.

About the Study

ANCHOR (ANti-VEGF Antibody for the Treatment of Predominantly Classic
CHORoidal Neovascularization in AMD) is a Phase III randomized,
two-year,
multi-center, double-masked, active-treatment controlled study comparing
two
different doses of Lucentis to PDT in 423 patients with predominantly
classic wet AMD.  Patients were randomized 2:1 to receive intravitreal
Lucentis injections (0.3 mg or 0.5 mg dose) once a month or PDT every
three
months for two years. Exclusion criteria included prior subfoveal laser
treatment, PDT or experimental treatments for wet AMD. Visual acuity was
measured using the Early Treatment Diabetic Retinopathy Study (ETDRS)
chart,
the standard method of quantifying visual acuity. The study is ongoing
in
the United States, Europe and Australia.  Based on the one-year results,
patients in the PDT alone arm of the study will have access to Lucentis
for
the remainder of the study.

Additional Phase III Studies
SAILOR
In November 2005, Genentech began enrollment in a Phase IIIb study,
SAILOR,
to make Lucentis available to eligible patients. SAILOR (Safety
Assessment
of Intravitreal Lucentis fOR AMD) is a Phase IIIb clinical study of
Lucentis
for patients with all types of new or recurrent active subfoveal wet
AMD.
It
is a one-year study designed to evaluate the safety of two different
doses
(0.3 mg and 0.5 mg) of Lucentis administered once a month for three
months
and thereafter as needed based on retreatment criteria. The study will
be
conducted at more than 100 sites in the United States and will enroll up
to
5,000 patients. Those interested in additional information about the
study
can call toll-free 1-888-662-6728.

MARINA
In July 2005, Genentech announced positive preliminary one-year results
from
the pivotal Phase III MARINA study (Minimally classic/occult trial of
the
Anti-VEGF antibody Ranibizumab In the treatment of Neovascular AMD), a
randomized, two-year, multi-center, double-masked, sham-injection
controlled
study evaluating the safety and efficacy of two different doses of
Lucentis
in 716 patients with minimally classic or occult wet AMD. Nearly 95
percent
of patients treated with Lucentis maintained or improved vision at 12
months. Additional one-year results include:

*       Twenty-five percent (59/238) of patients treated with 0.3 mg of
Lucentis and 34 percent (81/240) treated with 0.5 mg of Lucentis
improved
vision by a gain of 15 letters or more compared to approximately 5
percent
(11/238) of patients in the control group as measured by the ETDRS eye
chart.
*       Nearly 40 percent (188/478) of Lucentis-treated patients
achieved a
visual acuity score of 20/40 or better compared to 11 percent (26/238)
in
the control group.
*       Patients treated with Lucentis gained an average of seven
letters
in
visual acuity compared to study entry, while those in the control group
lost
an average of 10.5 letters.
*       The majority of patients treated with Lucentis (74.8 percent in
the
0.3 mg group and 71.3 percent in the 0.5 mg group) experienced a letter
improvement of zero or more compared to 28.6 percent in the sham group.

In October 2005, Genentech announced that patients in the sham arm of
the
MARINA study would be crossed over to active treatment with Lucentis.
Additional one-year data from the MARINA study will be presented at the
Macula Society Meeting in February.

 

PIER

Genentech is also conducting PIER (A Phase IIIb, Multi-center,
Randomized,
Double-Masked, Sham Injection-Controlled Study of the Efficacy and
Safety
of
Ranibizumab in Subjects with Subfoveal Choroidal Neovascularization with
or
without Classic CNV Secondary to Age-Related Macular Degeneration) with
184
patients in the United States.  In this trial, Lucentis is administered
once
per month for the first three months followed thereafter by doses once
every
three months for a total of 24 months.  Enrollment in this study is
complete, and preliminary results are expected in the second quarter of
2006.

 

Lucentis Safety Profile

In clinical trials to date, the most common side effects that occurred
more
frequently in the Lucentis arms (0.3 mg and 0.5 mg) than in the control
arms
were mild to moderate and included: conjunctival hemorrhage, eye pain,
increased intraocular pressure and vitreous floaters.

Serious ocular adverse events that occurred more frequently in the
Lucentis-treated arms were uncommon and included endophthalmitis and
intraocular inflammation (less than 1 percent for each). Among
non-ocular
serious adverse events, cerebral vascular events and myocardial
infarctions
were observed in all three arms of both the Phase III MARINA and ANCHOR
studies. The combined rate of these events in these two studies with
monthly
dosing was similar in the control and the 0.3 mg Lucentis arms (1.3
percent
and 1.6 percent respectively) and slightly higher in the 0.5 mg Lucentis
arm
(2.9 percent).

 

About AMD
AMD is a major cause of painless central visual loss and is the leading
cause of blindness for people over the age of 60.  The National Eye
Institute estimates that there are 1.6 million people with AMD in the
United
States alone and that this prevalence will grow to 2.95 million by 2020.
AMD occurs in two forms: dry and wet. 

The dry form is associated with atrophic cell death of the central
retina
or
macula, which is required for fine vision used for activities such as
reading, driving or recognizing faces.  The wet form is caused by growth
of
abnormal blood vessels, also known as choroidal neovascularization (CNV)
or
ocular angiogenesis, under the macula. These vessels leak fluid and
blood
and cause scar tissue that destroys the central retina.  This results in
a
deterioration of sight over a period of months to years.

 

About Lucentis
Lucentis(tm) (ranibizumab) is a humanized therapeutic antibody fragment
developed at Genentech and designed to bind and inhibit VEGF-A, a
protein
that is believed to play a critical role in angiogenesis (the formation
of
new blood vessels).  Lucentis is designed to block new blood vessel
growth
and leakiness, which lead to wet AMD disease progression and vision
loss.
Lucentis is being developed by Genentech and the Novartis Ophthalmics
Business Unit for diseases or disorders of the eye.  Genentech retains
commercial rights in the United States and Canada, and Novartis has
exclusive commercial rights for the rest of the world.

 

About Angiogenesis
Genentech is a leader in research and product development in the area of
angiogenesis, the process by which new blood vessels are formed.  In
1989
Napoleone Ferrara, M.D., and a team of scientists at Genentech conducted
seminal work in the field, which resulted in the identification and
cloning
of a gene termed Vascular Endothelial Growth Factor (VEGF), now known as
VEGF-A.  The VEGF-A protein is believed to play a critical role in
angiogenesis and serves as one of the key contributors to physiological
or
pathological conditions that can stimulate the formation of new blood
vessels.  The process of angiogenesis is normally regulated throughout
development and adult life, and the uncontrolled growth of new blood
vessels
is an important contributor to a number of pathologic conditions,
including
wet AMD.

Vitamin E and Treatment of Age-related Macular Degeneration

Following are the results of a recent study on Age-Related Macular Degeneration at Johns Hopkins University.

  Vitamin E Treatment of Macular Degeneration

             Is New Preventive Measure: Johns Hopkins University

      WASHINGTON, Jan. 23 2005 /PRNewswire/ -- Supplementation containing Vitamin E "provides an exciting preventive measure" for age-related macular degeneration, a professor of ophthalmology at Johns Hopkins University has concluded after taking part in a major ongoing research effort.

    "There are no other proven options for early intervention," Dr. Susan Bressler says in the coming February edition of the Johns Hopkins medical letter, Health After 50.

    Vitamin E intake of 400 milligrams, together with Vitamin C, beta carotene, and small amounts of zinc and copper oxides, reduces the likelihood of disease progression by 25 percent in patients with intermediate age-related macular degeneration, or AMD, the research has determined.

    "Supplementation with this formulation also reduced the risk of vision loss by 19 percent over five years in these patients," the Johns Hopkins publication reported.

    Until now, there has been no proven treatment to slow the progression of disease and possible vision loss in people with dry AMD, the most common form of the condition, Dr. Bressler said.

    Major clinical trials of the Vitamin E and other supplementation started two years ago, and a follow-up report was published recently in the Archives of Ophthalmology.  Researchers concluded in the report that "if every American with intermediate AMD took these vitamins and minerals, more than 300,000 people could avoid AMD-associated vision loss over the next five years."

    More than 1.6 million Americans over age 60 have age-related macular degeneration, which is the most common cause of visual impairment and blindness in the U.S.

Major Breakthrough in Treatment of Age Related Macular Degeneration

In a major study of over 3,000 patients with age-related macular degeneration, the "Age-Related Eye Disease Study Research Group", funded by the National Institutes of Health (NIH), found that large doses of antioxidants plus zinc delayed progression of ARMD.  Eye doctors at 11 research centers measured and assessed retinal photos and measured visual acuity in high risk groups of patients with ARMD who received one of the following;

1. Antioxidants (500mg vitamin C; 400 IU Vitamin E; and 15 mg beta carotene) alone,

2. Zinc (80 mg as zinc oxide and copper, 2 mg as cupric oxide) alone,

3. Antioxidants plus zinc (both as listed above),

4. placebo (sugar pill).

The results showed that patients that received the antioxidants plus zinc had a reduction in the rate of loss of visual acuity.  No significant side effects were observed.  It is concluded that if you're older than 55, have intermediate or advanced ARMD, and are without contraindications (such as smoking), that you should consider taking supplemental antioxidants plus zinc to reduce the progression of the disease. See your eye doctor to see if you're a candidate for such therapy.   (Archives of Ophthalmology, vol. 119, oct, 2001, p1417-1436)
