Health Canada Approves New Cream Treatment for Skin Cancer
ALDARA is the first new treatment approved in Canada
for basal cell carcinoma in 30 years

Pro Golfer David Barr urges Canadians
to take action against skin cancer

TORONTO, Jan. 6 /CNW/ - Health Canada has approved ALDARA(TM)
(imiquimod)
Cream, 5%, a topical prescription medication for the treatment of
superficial
basal cell carcinoma (sBCC) - a form of non-melanoma skin cancer.
ALDARA is
the first new treatment for this type of cancer to be approved in
Canada in
close to 30 years and is the first in a new class of medications called
immune
response modifiers. The medication works by triggering the body's
immune
system to find and kill mutated cells on the outer layer of the skin.
"Standard skin cancer treatment options include scraping, burning,
radiation, or surgically removing cancer lesions from the skin, which
can be
uncomfortable and sometimes disfiguring," says Dr. Goldstein,
consultant
dermatologist at the University Health Network, Toronto Western
Hospital. "But
with the availability of ALDARA for sBCC, Canadians have another
effective
option, which is associated with little or no discomfort, and may not
cause
the long-term scarring that can be seen with more invasive treatments.
This
therapy can replace surgical options for superficial BCCs, with good
cure
rates and an acceptable side effect profile."
Skin cancer is the most common of all cancers affecting approximately
82,000 Canadians(1). Over the last 15 years its incidence has increased
by
two-thirds (67 per cent)(2). Basal cell carcinoma accounts for 80 per
cent of
all skin cancers(3).
"When I was diagnosed with basal cell carcinoma (BCC), I was shocked -
skin cancer was never something I was concerned about," says Canadian
Hall of
Fame and Senior PGA Championship golfer, David Barr. "Now I know the
importance of examining my skin regularly and seeing my doctor if I
notice
anything unusual. For many of us the damage from years of sun exposure
is
already done, so early detection is crucial. If caught early, BCC is
highly
treatable."
ALDARA is a cream that is applied at home by the patient and unlike
most
approved therapies, is non-invasive, which means it does not involve
surgery.
In clinical trials involving 364 patients with primary sBCCs, 82 per
cent of
patients treated with ALDARA achieved complete disease clearance
confirmed by
biopsy, compared with only three per cent in the placebo group(4).
"Finding effective and patient-friendly options is important in
advancing
the treatment of non-melanoma skin cancer," comments Dr. Jason Rivers,
dermatologist and active staff member at the British Columbia Cancer
Agency,
and professor of dermatology at the University of British Columbia in
Vancouver. "Not only is ALDARA effective, but it's exciting because it
works
with the body's own immune system to fight cancer from within, rather
than
treating it invasively from the outside."
ALDARA is applied five times per week, for six weeks, to sBCC lesions
with a maximum diameter of two centimetres, confirmed by biopsy,
located on
the trunk of the body, neck, or extremities (excluding hands and feet).
In
clinical trials, the most frequent reactions reported by ALDARA
patients were
local skin reactions, including erythema (redness), and scabbing at the
application site. Although 97 per cent of patients reported erythema,
only
three per cent reported pain and only one per cent of patients
discontinued
treatment due to local skin or application-site reactions. Scarring was
not
reported as a result of ALDARA treatment at the 12 week post-treatment
evaluation.
ALDARA was first approved by Health Canada in 1999 for the treatment of
external genital and perianal warts, caused by the human papillomavirus
(HPV).
In June 2004, Health Canada approved ALDARA for the treatment of
actinic
keratosis, a precancerous skin condition that can lead to squamous cell
carcinoma, another form of non-melanoma skin cancer.

Basal Cell Carcinoma
Basal cell carcinoma affects approximately 65,000 Canadians(5).
Superficial BCC is a type of BCC that typically occurs on the torso and
may
appear on the face. It appears as well-defined, red, scaly patches that
can
resemble eczema or psoriasis. Like other skin cancers, sBCC is caused
by over
exposure to the sun's damaging rays.
Basal cell carcinoma lesions generally grow slowly and have up to a
95 per cent treatment success rate if caught early(6). If left
untreated,
BCC tumours can continue to grow, eventually invading and causing
damage to
surrounding tissues.
