Dear
Colleagues,
We are now
over halfway through the 2400 patient accrual on the 01062
trial, and accrual continues to go very well at 70-75 patients/month.
With your willingness to identify just one additional patient
per month whom you feel would benefit from this therapy, we
can easily increase accrual to 100 patients/month and complete
accrual in less than one year.
The safety of the study is now being evaluated by the Independent Data
and Safety Monitoring Committee. From my perspective as the principal
investigator, the tolerability of the docetaxel/capecitabine combination
at the new doses of 75/1650 mg/m2 is much improved over the
original starting doses. I do recommend the use of prophylactic Nystatin
swish and spit q.i.d. starting with day 2 of each cycle of docetaxel/capecitabine
to prevent yeast mucositis, which might occur between days 4 and 7 of
the cycle, complicating docetaxel/capecitabine delivery following AC
in a subset of patients. I urge you strongly to encourage your patients
who do develop toxicity with the docetaxel/capecitabine combination to
continue with the treatment, with an appropriate dose reduction per protocol,
because a 25% capecitabine dose reduction in those patients who require
it results in markedly reduced toxicity. So doing will give patients
the best chance of benefiting from adjuvant chemotherapy, since the docetaxel/capecitabine
combination has a very strong clinical rationale and upholds the study
integrity, helping to ensure that we and our participating patients will
determine whether capecitabine improves the outcome of early-stage breast
cancer.
The exciting results of Dr. Coombes’ IES trial of 2-3 years of
tamoxifen followed by 2-3 years of exemestane promises to change adjuvant
endocrine therapy of breast cancer. We will be amending the protocol
to allow postmenopausal patients on tamoxifen on 01062 to switch to exemestane,
probably once they have been on tamoxifen for 2-3 years. I am discussing
this issue now with the study sponsors and we will get further information
about this issue out to the USON network soon. This will require a protocol
amendment, so I request that patients be continued on tamoxifen for now,
since the first patients enrolled on 01062 are just over a year into
their tamoxifen therapy.
Aren’t adjuvant breast cancer trials fascinating in these times
of very rapid accrual and rapid progress?! With all of us in US Oncology
working together we can complete accrual to 01062 within the year and
bring these hopefully important results to future breast cancer patients
and their physicians worldwide.
With best regards,
Joyce O’Shaughnessy, MD
