New data on multiple sclerosis vaccine
C onnective therap eu tics, Inc
(N A SD A Q CN CT) announced today
that results from Phase l/ll clinical
testing o f T-cell Receptor (TCR)
peptide vaccines for the treatment of
multiple sclerosis will be published
in the October 1996 issue o f the
Journal o f Natural Medicine.
The results from this pilot study
indicated that patients who responded
immunologically to TCR vaccines
experienced stabilization o f disease
without side effects during one year
o f therapy
The Phase l/ll physician-spon
sored study was conducted by a team
o f scientists led by Connective’s
collaborator, Arthur A. Vandenbark,
Ph D. o f N euroim m unology Re
search, Veterans Affairs Medical
Center, Portland and Oregon Health
Sciences University.
The double-blind, placebo-con
trolled trial involved 23 patients with
chronic, progressive multiple scle
rosis who were treated for 12 months
with a native or substituted version
o f a V beta 5.2 ICR peptide vaccine
or placebo. Successful peptide vac
cination boosted protective T-cells
and low ered pathogenic T-cells
thought to cause the disease.
“These promising early data sup
port our decision to conduct addi
tional studies in a larger population
o f progressive multiple sclerosis pa
tients," said W Scott Harkonen,
M.D., senior vice president o f Prod
uct Development and Operations at
Connective. “ We believe these clin
ical observations in multiple sclero
sis generated by Dr Vandenbark’s
group also serve as indications o f the
potential therapeutic value o f TCR
technology as a platform to develop
vaccines for other autoimmune and
connective tissue diseases.”
In the Phase 1/11 study, all TCR
peptide vaccine responders (6/6)
were clinically improved or stable,
while only 7 o f 17 non-responders
were improved or stable There were
no responders in the placebo group
The vaccines were well-tolerated,
with no evidence o f adverse events
a ttrib u ta b le to TCR p e p tid e
treatment.
Additional findings in the Nature
M e d ic in e re p o rt su g g e st that
protective (regulatory) cells elicited
by the vaccine not only inhibit
their specific target pathogenic
T-cells, but also inhibit “bystan
der" pathogenic T-cells in the area
o f inflammation in the nervous sys
tem.
This information implies that the
target T-cells need only represent a
fraction o f the total pathogenic
population for the vaccine to be
effective
an important finding as
multiple sclerosis is believed to be
caused by a heterogeneic (mixed)
population o f T-cells.
Ihe publication o f this data coin
cides w ith Connective’s plans to sub
mit an Investigational New Drug
Application to conduct a Phase l/ll
study o f native and substituted TCR
V beta 5.2 peptide vaccines in pro
gressive multiple sclerosis. The study
will be a multicenter, double-blind,
placebo-controlled trial which is
expected to enroll 100 patients. Con
nective plans to compare the immu
nogen ¡city o f the two vaccines against
placebo.
Dr Vandenbark commented. "We
are excited about the potential of
ICR vaccines as th erap ies for
multiple sclerosis and look forward
to participating in C onnective’s
upcoming trial. Boosting the body ’s
natural immunity with vaccines such
as these may provide long-term clin
sure to rise with age. But when it
does, if s still treatable,” he said. "By
lowering blood pressure, you can
reduce the risk o f death from heart
attack and stroke.”
The key is m aking healthful
lifestyle choices, such as eating low-
salt, low-fat and low -cholesterol
foods, not smoking, and watching
your weight.
Among the bestchoices? Exercise.
“Recent studies have shown that
sedentary older adults who gradually
add physical activity to their lifestyle
can significantly improve cardiovasc
u lar p e rfo rm a n c e ,” luchi said.
Walking, water aerobics, and dancing
are good ways to improve blood cir
culation and make you feel good.”
Medications like “clot-busting”
Streptokinase and aspirin can help
prevent blood clots that cause heart
attacks. Studies have shown that
postmenopausal women who take
estrogen supplements seem to be pro-
tected against heart attacks.
A ccording to L uchi, ad u lts

and have a stress test before begin

Luchi says it’s important to
know hear, attack warningsigns:
♦ Chest discomfort spreading to
the neck, shoulders, and arms
♦ S w e a tin g , n a u se a a n d
shortness o f breath
♦ Dizziness or fainting
In some older people, a heart
attack can occur with few or no
symptoms. "Heart attacks come in
different forms—from no symptoms
to severe pain,” Luchi said.
If any symptoms appear, Luchi
says d o n 't ignore them . “G et

Shriners fre e screening clinic
Never too late to prevent heart disease
It’s never too late to prevent heart
disease, says a geriatrics expert in
The DeBakey I leart Center at Bay lor
College o f Medicine in Houston.
“ Even if you are 70 years old,
exercising and eating right can
decrease your heart disease risk,”
said Dr. Robert Luchi, a professor
o f medicine and director o f the
Huffington C enter on Aging at
Baylor. “But the earlier in life you
start, the better.”
Heart disease is the leadingcause
o f death o f Americans and is more
common in older people. The risk

dramatically after age 75.
Coronary artery diseases, such
as atherosclerosis (artery blockage),
often take up to 40 years or more to
progress to a heart attack. And, like
high blood pressure, heart disease is
not necessarily a natural part o f
aging, Luchi said.
“ It’s not normal for blood pres-
ical benefit by arresting disease pro
gression."
As with other vaccines, the TCR
technology is being developed to help
the body recognize and destroy patho
gens. In the case ofautoim m une dis
eases. the pathogens are believed to
be T-cells. TCR vaccines are manu
factured from the receptor portion o f
pathogenic T-cells and injected into
the patient to elicit a heightened im
mune response against the T-cells
thought to cause autoimmune dis
ease.
Connective Therapeutics’ TCR
peptide vaccines are being designed
to boost the naturally occurring con
trol arm o f the immune system
believed to function inefficiently in
immune-mediated diseases.
These vaccines are expected to

I he Portland Shriners Hospital
for children will hold a free orthope
dic and plastic surgery'screening clin
ic on Saturday, Nov 2 from 8 a.m. to
2 p in. in the hospital's outpatient
clinic. 3181 S. W. Sam Jackson Park
Road. I faccepted, children at Shriners
Hospital are treated free o f charge.
"Last year, when we offered this
clinic we saw 112 children in six
hours,” said Phyllis Newton, Direc
tor o f Community Outreach. “ We
were stunned that there were so many
families who did not know about our
free medical services ”
Shriners Hospital accepts children
up to age 18 who have bone, muscle or
joint problems, or who have plastic
surgery needs -- such as for burn scars,
clef, lip palate and facial anomalies.
Most patients at Shriners have con
genital, life-long problems such as
cerebral palsy, spina bifida, muscular
dystrophy or club foot. Other children
suffer accidents and illnesses, such as
losing a hand or leg. Other common
conditions seen include scoliosis --
curvature of the spine - and congenital
hip dislocation.
Because care at Shriners Hospital
is free, there is always a waiting list
o f several hundred names. However,
children seen at a screening clinic
generally can begin their care w ithin
two months. (The hospital does not
provide emergency services, such as
for broken bones or acute burns.)
"We are especially interested in
making sure we are reaching out to
minority' and low income families,"
Newton said. "We are making every
effort to inform those communities
that we are available to them by con
tacting community clinics, distribut
ing flyers in english and Spanish, and
working through all news media.” A
Spanish interpreter will be at the clinic,
and interpreters for other languages
will be provided if requested in ad
vance Tree return Tri-Met passes will
be given to anyone who arrives by bus
(#8 from downtown).
No appointments are needed to be
seen at the Screening clinic. Hospital
surgeons will be on hand to evaluate
every child who arrives forcare. Al
though the wait may be long at times,
families will be entertained by Shrine
clowns. Free refreshments will also
be available to sustain those who are
waiting. If, for some reason a child is
not appropriate for care at Shriners
Hospital, the family will be referred.
Generally, Shriners Hospital ac
cepts al I patients for care if treatment
would benefit the child and if treat
ment at another facility would put a
financial burden on the family.

Flab is now the norm
For the first time, overweight peo
ple outnumber normal-size ones in
the United States, according to the
latest government statistics, released
Tuesday.
The reasons are not entirely clear

tional C en ter for H ealth S ta tis

She noted the development o f the
TV remote control, wh ich keeps peo
ple planted on the couch all evening,
and fear o f crime, which gives them
another reason to stay inside.
“It's just eating too much,” con
tended Dr. Albert J. Stunkard o f the
U n iv e rsity o f P e n n sy lv a n ia .
’’Physical activity hasn't increased
enough to make up for it.”
Whatever the reason, the latest
government figures show just how
fat the country has gotten.
Federal guidelines suggest that
people should keep their body mass
indexes under 25. Anything more
than that is too much
Body mass index, or BMI, is
quickly becoming the standard way
oftalking about obesity, since it is an
easy way to compare the fatness o f
people o f different heights. BMI is
body weight in kilograms divided by
height in meters squared. A woman
5-foot-4 who weights 145 pounds
has a BMI o f 25.
The National Health and Nutrition
Examination Survey, conducted on
30.000 people between 1991 and
1994, shows that 59 percent o f Amer
ican men and 49 percent o f women
have BM Isover25. Ten years earlier,
5 1 percent o f men and 4 1 percent of
women were this heavy.
Flegal presented the figures at a
meeting o f the North A merican
Assoc ¡at ion for the Study o f Obesity.
“ It’s been clear for several years
that Americans are getting fatter, and
it’s accelerating. That’s troubling,”
said Dr. Tim Byers o f the University
ofColorado Health Sciences Center
People in their 50s are the fattest.
The survey found that 73 percent of
men and 64 percent o f women this
age have BMIs over 25.
However, the survey also found
overweight increasing among pre-

teen children, too.
Extreme obesity is also becoming
more common. The survey found 2
percent o f men and 4 percent of
women have BMIs over 40 - double
the rate a decade ago. A 5-foot-4
women with a BMI of40 weighs 230
pounds.
W hilea BMI of25 is probably not
p a rtic u la rly bad, e x p e rts say
significant health problems begin to
emerge when people’s BMIs hit 27.
T hat’s 155 pounds for the 5-foot-4
woman.
Flegal noted, however, that some
w eight-related health ills do not
appear to be rising with Americans'
increasing weights. I he survey shows
that cholesterol levels are falling,
and blood pressure appears to be
holding steady or dropping slightly.
On the other hand, the statistics
suggest that diabetes, which is also
closely related to weight, may be
increasing.
W hile there is no universally
accepted definition o f obesity, some
experts call it a BMI o f 30 or more.
This is 175 pounds for the 5-foot-4
woman.
For sonic reason, we all think we'rt?
tile one person who doesn’t e \e r
hav e to think about i linlc-acrol.
But the truth is, we all have to keep
our hearts healthy. So we should all
eat foods low in saturated fat, total fat,

and watch our weight. We all can.

average year, the flu claims the lives of
up to 20,000 Americans, 90 percent of

Here are the facts: Last year’s shot
will not protect you from this year's
flu Because the virus takes on a d i fièr
ent form every year, you need to get a
flu shot every year. And the ideal time
to get yours is between October and
mid November Let me be clear: The
flu shot will not make you sick. And. if
you are enrolled in Medicare Part B.
you can get yours absolutely free
Unfortunately, recent statistics show
that only about 55 percent ofO regon’s
residents age 65 or older protect them
selves by getting a flu shot each year.
We can and must do better.
Remember, if you get the flu shot
today, you can avoid getting sick to
morrow. So, get the flu shot - not the
flu.
