VANCOUVER, June 15 /PRNewswire-FirstCall/ -- QLT Inc. (NASDAQ:
QLTI; TSX: QLT) today announced that twelve-month primary analysis
results from the Novartis sponsored Phase II MONT BLANC study were
presented on June 14, 2009 during the 17th Congress of the European
Society of Ophthalmology in Amsterdam, the Netherlands. MONT BLANC
is the European study of the Novartis sponsored SUMMIT clinical
trial program which investigates the efficacy and safety of
combining Visudyne(R) (Novartis Pharma AG) and Lucentis(R)
(Novartis Pharma AG, Genentech Inc.). SUMMIT also includes the
DENALI study in the US and Canada and the EVEREST study in Asia.
MONT BLANC is a 24-month randomized, double-masked, multicenter
trial in patients with subfoveal choroidal neovascularization
secondary to age-related macular degeneration. The purpose of the
study is to evaluate whether Visudyne combined with Lucentis is not
inferior to Lucentis monotherapy with respect to the mean change
from baseline in visual acuity (VA) and to evaluate the proportion
of patients with a treatment-free interval of at least three months
duration after Month 2. At the Month 12 examination, mean VA in the
Visudyne combination therapy group improved 2.5 letters from
baseline compared with a 4.4 letter improvement in the Lucentis
monotherapy group. In the combination therapy group, 96% of
patients had a three-month treatment-free interval, compared with
92% in the Lucentis monotherapy group. Twelve-month results of the
MONT BLANC study show that combining standard-fluence Visudyne with
Lucentis 0.5 mg can deliver VA improvements that are non-inferior
to a Lucentis monotherapy regimen with three Lucentis loading doses
followed by injections on a monthly as-needed basis
(non-inferiority margin of 7 letters). There was no significant
difference between the combination and monotherapy groups with
regard to proportion of patients with a treatment-free interval of
at least three months duration after Month 2. There were no
unexpected safety findings, and adverse event incidence was similar
between treatment groups. Additional post hoc analysis showed that
85% of patients in the Visudyne combination therapy group, compared
with 72% in the Lucentis monotherapy group, had a treatment-free
interval of at least four months duration after Month 2. Median
time to first retreatment after month 2 was extended by ~1 month in
the combination group (month 6) versus the monotherapy group (month
5). Patients in the combination group received, on average, a total
of 4.8 ranibizumab injections compared with 5.1 in the monotherapy
group and a total of 1.7 Visudyne treatments compared with 1.9 sham
treatments in the monotherapy arm. Results are based on ITT
analyses (with LOCF); per-protocol analyses yielded similar
results. Overall, only 15 patients discontinued the study before
Month 12 (6%). "MONT BLANC provided the first data within the
SUMMIT clinical trial program and showed that patients treated with
Visudyne combination therapy had non-inferior visual acuity to
patients treated with Lucentis monotherapy," said Bob Butchofsky,
Chief Executive Officer of QLT Inc. "The results from DENALI, which
includes a Visudyne reduced fluence arm, and EVEREST, which studies
combination therapy in polypoidal choroidal vasculopathy, may add
to the knowledge about the potential benefits of combining Visudyne
and Lucentis." About MONT BLANC Phase II Study The MONT BLANC study
is a Phase II, multicenter, randomized, double-masked study
comparing standard-fluence Visudyne-Lucentis combination therapy to
Lucentis monotherapy in 255 subjects with choroidal
neovascularization (CNV) secondary to wet age-related macular
degeneration (wet AMD). Subjects were randomly assigned to one of
two treatment groups: Standard-fluence Visudyne (600 mW/cm2 for 83
seconds to deliver 50 J/cm2) followed by same day intravitreal
Lucentis (0.5 mg), or Lucentis monotherapy (0.5 mg). The Lucentis
monotherapy group received sham Visudyne treatment to maintain
masking. Standard-fluence Visudyne (or sham) was administered at
baseline and then as needed at intervals of at least three months
if required based on predefined re-treatment criteria. Lucentis was
administered to both treatment groups with three loading doses
followed by monthly treatment if required based on predefined
re-treatment criteria. Patients were evaluated for VA, anatomical
changes and safety at every monthly visit, and the need for
retreatment was assessed at monthly visits from Month 3 to Month
11. Re-treatment was based on assessment of central retinal
thickness (CRT) (increase of greater than or equal to 100
(micro)m), presence of subretinal fluid, as assessed by optical
coherence tomography (OCT), presence of new subretinal hemorrhage
as assessed by ophthalmoscopic examination, presence of CNV leakage
as assessed by fluorescein angiography (FA) and decreases in VA of
greater than 5 letters as assessed by an Early Treatment Diabetic
Retinopathy Study (ETDRS) chart. As-needed Lucentis after three
loading doses is a standard regimen in Europe, but not in the US,
and combination therapy for AMD is not approved for marketing by
regulatory agencies. The study duration is 24 months with a planned
primary analysis when all subjects completed 12 months of
follow-up. At baseline, mean VA letter score was 54 to 55 across
treatment groups. About Visudyne Visudyne therapy is a two-step
procedure involving the intravenous administration of the drug into
the patient's arm. A non-thermal laser light is then shone into the
patient's eye to activate the drug. This produces a reaction that
closes the abnormal leaky vessels, resulting in a stabilization of
the corresponding vision loss. Visudyne is approved worldwide for
the treatment of a form of wet AMD, the leading cause of legal
blindness in people over the age of 50, and has been used in more
than two million treatments worldwide. Visudyne is commercially
available in more than 80 countries for the treatment of
predominantly classic subfoveal CNV. In addition, over 60 countries
have approved Visudyne to treat one or more other macular
neovascular conditions such as minimally classic and occult with no
classic AMD lesions, pathologic myopia and presumed ocular
histoplasmosis. Visudyne is generally well tolerated and has a well
established safety profile. The most commonly reported side effects
include injection site reactions and visual disturbances. In
addition, some patients experienced back pain, usually during the
infusion. Using the approved light dose of 50J/cm2 between 1% and
5% of patients experienced a substantial decrease in vision in the
first 7 days with partial recovery in some patients. Recent studies
suggest that halving the light dose/fluence by halving the fluence
rate may lower the incidence of visual disturbances with possibly
better visual outcomes than the standard light dose used in this
study. After treatment, patients should avoid direct sunlight for
five days to prevent sunburn. People with porphyria should not be
treated with Visudyne. About QLT QLT Inc. is a global
