YM BIOSCIENCES ANNOUNCES FIRST PATIENT ENROLLED IN MULTI-NATIONAL, RANDOMIZED,
DOUBLE-BLIND TRIAL OF NIMOTUZUMAB IN NON-SMALL-CELL LUNG CANCER
MISSISSAUGA, ON, March 16 /CNW/ - YM BioSciences Inc. (NYSE Alternext
US:YMI, TSX:YM, AIM:YMBA), an oncology company that identifies, develops and
commercializes differentiated products for patients worldwide, today reported
the enrollment of the first patient into its multinational trial of
nimotuzumab for the treatment of patients with non-small-cell lung cancer
(NSCLC).
This Phase II randomized, double-blind, placebo-controlled study will
examine the effect of nimotuzumab when added to palliative radiotherapy to
treat NSCLC. The trial has a target enrollment of 128 patients and is being
conducted internationally with 12 centers contracted to participate in Canada.
Patients diagnosed with Stage IIb or III NSCLC ineligible for curative
treatment, or Stage IV NSCLC patients with progressive disease within the
chest, are eligible to enroll into this study. Palliative radiotherapy
constitutes a standard treatment modality in this patient population.
The Principal Investigator, Dr. Gwyn Bebb of the Tom Baker Cancer Centre
in Calgary, Canada commented, "The data we presented at ASCO 2008 encouraged
us to proceed with this Phase II trial as soon as was feasible, and we are
obviously excited to get the study off the ground in such a timely manner. Our
experience to date leads us to expect a successful outcome from this important
trial for these severely underserved patients. Patients in the earlier trial
enjoyed a good quality of life while being on nimotuzumab every two weeks, in
some cases, for over a year. Clearly, it is critical to assess the specific
contribution of nimotuzumab to this outcome and that is why the Phase II study
is scientifically rigorous, being both randomized and blinded. We anticipate
that accrual to the study will be quite brisk and that we will meet the
planned timepoints."
"The blinding of this trial is feasible because nimotuzumab does not
produce the severe toxicities typical of the EGFR class of antibodies. This
unique safety profile provides us with the expectation of a significant
competitive advantage and holds out the prospect for an extension in survival
at an acceptable quality of life for patients who have been told that they are
being treated palliatively," said David Allan, Chairman and CEO of YM
BioSciences. "This trial is one of two that we are launching in indications in
which nimotuzumab's demonstrated and differentiated mechanistic attributes are
expected to show that it is as effective as the currently marketed antibodies
while continuing to demonstrate its best-in-class prospect."
This trial is being launched subsequent to a successful lead-in Phase I
trial in a similar patient population. Initial data from the lead-in study
were presented at ASCO 2008, where the median Overall Survival (OS) reported
for 18 patients was 13.8 months. The lead-in study findings were subsequently
corroborated by results from an independent Phase I performed under the same
protocol by Kuhnil Pharmaceutical Corporation, the licensee for nimotuzumab in
Korea. In that trial a median OS in the Asian population of 11 months was
reported and the two studies bring the aggregate number of patients treated
under the protocol to 33. These survival data compare well with historical
survival times of six to nine months reported in a similar but fitter or
healthier patient populations ((Int J Radiat Oncol Biol Phys. 2002 Nov
1;54(3):719-28.) (Clin Oncol (R Coll Radiol). 1996;8(3):167-75)).
"The palliative NSCLC patient population represents a significant unmet
medical need where progress over the last 30 years has been primarily limited
to adjustments in radiotherapy protocols, with no major improvements to
patients," said Dr. Leonardo Viana Nicacio, M.D., Director, Clinical Affairs
for YM BioSciences. "A therapy that has the potential to maximize symptom
palliation, improve survival, minimize toxicity and reduce the need for
re-irradiation would be most welcome."
The incidence of NSCLC exceeds 367,000 new cases in the seven major
pharmaceutical markets with around 25% of patients in various jurisdictions
being treated with palliative radiotherapy for chest disease. A recent
meta-analysis from Canadian investigators (J Clin Oncol. 2008 Aug
20;26(24):4001-11) demonstrated that a better palliative treatment resulted in
a survival benefit. Achieving greater local control with radiotherapy alone
can provide more timely palliation of thoracic symptoms than chemotherapy
alone and may be the only treatment option for poor ECOG-status patients, or
those who have declined chemotherapy or progressed despite systemic therapy.
One approach to improve local control without the toxicity of chemotherapy is
to administer agents such as nimotuzumab that enhance the toxicity of
radiotherapy to cancer cells.
The trial enrolment is anticipated to take 18 months and a follow-up
period of 18 months will be required to complete the trial. The protocol for
the trial is being reviewed by nimotuzumab licensees worldwide and
participation by several of the nimotuzumab consortium members is anticipated.
Such participation would increase the rate of recruitment and reduce
time-to-completion. The primary endpoint of the trial is to evaluate the
difference in OS with secondary endpoints being Response Rate, Time to
Progression, Progression-Free Survival and Quality of Life.
About YM BioSciences
YM BioSciences Inc. is a life sciences product development company that
identifies and advances a diverse portfolio of promising cancer-related
products at various stages of development. The Company is currently developing
two late-stage products: nimotuzumab, an EGFR-targeting Affinity-Optimized
Antibody(TM), and AeroLEF(R), a proprietary, inhaled-delivery composition of
free and liposome-encapsulated fentanyl. YM has proven regulatory and clinical
trial expertise and a diversified business model designed to reduce risk while
advancing clinical products toward international approval, marketing and
commercialization.
Nimotuzumab is a humanized monoclonal antibody in development worldwide,
targeting multiple tumor types primarily in combination with radiation and
chemoradiation. It is significantly differentiated from all other currently
marketed EGFR-targeting agents due to its remarkably benign side-effect
profile. Nimotuzumab's anti-tumor activity has led to its approval for
marketing in over 12 countries. In more than 3,500 patients reported as having
been treated with nimotuzumab worldwide to date, no Grade IV incidents of
radiation dermatitis have been described, severe rash has not been observed
and reports of the other severe side-effects that are typical of
EGFR-targeting molecules have been rare. Nimotuzumab is licensed to YM's
majority-owned subsidiary, CIMYM BioSciences Inc., by CIMAB S.A., and was
developed at the Center of Molecular Immunology. YM is developing AeroLEF for
the treatment of moderate to severe acute pain. The product is differentiated
from other approaches using fentanyl because patients can individually control
the analgesia required for their differing intensities of pain. AeroLEF met
all endpoints in a randomized Phase II trial and is currently being prepared
for late-stage development internationally.

the following: that nimotuzumab will continue to demonstrate a competitive
safety profile in ongoing and future clinical trials; that AeroLEF(R) will
continue to generate positive efficacy and safety data in future clinical
trials; and that YM and its various partners will complete their respective
clinical trials within the timelines communicated in this release. We
