Five Phase III Early-Stage Breast Cancer Studies Underway With GEMZAR
CHICAGO, June 2 /CNW/ -- GEMZAR(R) (gemcitabine HC1 for injection),
approved in combination with paclitaxel (Taxol(R)) in the first- line,
post-surgical treatment of metastatic breast cancer, was the subject of a
study presented today with encouraging results in the pre-surgical treatment
of breast cancer. The study was presented at the 43rd Annual Meeting of the
American Society of Clinical Oncology (ASCO).
Results showed that adding GEMZAR to the current standard-of-care
treatment was a promising regimen for patients with stage II-III breast
cancer. Eli Lilly and Company, the manufacturer and marketer of GEMZAR, also
cited five completed or ongoing Phase III trials which will further study
GEMZAR as a chemotherapeutic foundation for the treatment of early-stage
Today's Phase II study (Abstract No. 595(i)) evaluated the addition of
GEMZAR to the current standard-of-care of epirubicin and cyclophosphamide
followed by paclitaxel in patients with stage II-III breast cancer. The
treatment schedule was a dose-dense sequential neoadjuvant (pre-surgical)
chemotherapy combination, meaning that the combination was administered at
shorter intervals between treatments. Results showed a promising regimen in
terms of pathologic complete response (pCR-the absence of invasive tumor in
the breast). In addition, patients who tested positive for the HER-2 gene also
were given trastuzumab (Herceptin(R)) and demonstrated additional response.
"The data released today reflects our ongoing, aggressive research plan
involving GEMZAR as a key therapeutic foundation for the treatment of breast
cancer," said Allen Melemed, M.D., medical director, global oncology at Lilly.
"We are encouraged with the activity GEMZAR has shown in this breast cancer
Enrollment has been completed in one trial, and is ongoing in an
additional four, Phase III early-stage breast cancer studies evaluating the
addition of GEMZAR to commonly-used treatment regimens. Two adjuvant (post-
surgical) therapy trials, NSABP B-38 (4,400 patients) and TANGO (3,000
patients), will compare the addition of GEMZAR to the paclitaxel arm of each
study. A third adjuvant trial, SUCCESS (3,600 patients), will compare the
addition of GEMZAR to a docetaxel-based regimen. Two additional trials, which
are neoadjuvant specific, NSABP B-40 (1,200 patients) and Neo-TANGO (800
patients), will evaluate the addition of GEMZAR to the paclitaxel or docetaxel
arm of the treatment regimen. For more information on these studies, log on to

The trial enrolled stage II-III breast cancer patients (with a median age
of 45), including inflammatory tumors, a type of breast cancer that causes the
breast to swell, redden and feel warm. Of the 73 patients enrolled in the
study, 42 (57.5%) were classified as T2; 12 (16.5%) as T3, and; 19 (26%) as
T4, which included 13 patients with inflammatory tumors. A T-classification
represents the stage of the tumor with T4 being the most advanced. A biopsy
was performed before treatment for the biomarker component of the study.
Patients received a first sequence of epirubicin and cyclophosphamide
(90/600 mg/m squared) for three cycles followed by a second sequence of
paclitaxel and GEMZAR (150/2500 mg/m squared) for six cycles. Treatment was
administered on day one, every two weeks, with growth factor support. HER-2
positive patients (20 patients, 27.3%), were given trastuzumab (2 mg/kg with a
loading dose 4 mg/kg) concomitantly. Afterward, the patients underwent
surgery, radiotherapy and adjuvant hormonal therapy according to institutional
All patients from the study showed response to the regimen. Of the entire
study group, 27 (36.9%) patients achieved a pCR (absence of invasive tumor in
the breast), with 50% representation from the HER-2 positive patients who also
were given trastuzumab. Forty-seven patients (64.4%) underwent conservative
The grade 3/4 hematological toxicities were: leukopenia in six patients
(9%); neutropenia (a decrease in white blood cells) in eight patients (12%),
and; anemia (a decrease in red blood cells) in one (2%). Nausea (13%) and
vomiting (15%) were the most frequent grade 3/4 non-hematological toxicities.
Asymptomatic decrease in cardiac ejection fraction was observed in one patient
treated with trastuzumab with subsequent normalization.
About Breast Cancer
Breast cancer is the most common form of cancer among women, affecting
nearly one out of every eight women.(ii) The disease is diagnosed in more
than 1.1 million women worldwide each year.(iii) Breast cancer progresses in
stages based on tumor size, how the cancer affects the lymph nodes and whether
it has metastasized to other parts of the body.(iv) In general, individuals
with earlier stages of disease have better chances for long-term survival and
GEMZAR in combination with paclitaxel is indicated for the first-line
treatment of patients with metastatic breast cancer after failure of prior
anthracycline-containing adjuvant chemotherapy, unless anthracyclines were
GEMZAR is indicated in combination with cisplatin for the first-line
treatment of patients with inoperable, locally advanced (stage IIIA or IIIB),
or metastatic (stage IV) non-small cell lung cancer.
GEMZAR is indicated as first-line treatment for patients with locally
advanced (nonresectable stage II or stage III) or metastatic (stage IV)
adenocarcinoma of the pancreas. GEMZAR is indicated for patients previously
treated with 5-FU.
GEMZAR in combination with carboplatin is indicated for the treatment of
patients with advanced ovarian cancer that has relapsed at least 6 months
after completion of platinum-based therapy.
Important Safety Information for GEMZAR
Myelosuppression is usually the dose-limiting toxicity with GEMZAR
Known hypersensitivity to GEMZAR. Anaphylactoid reaction has been
Infusion times of GEMZAR longer than 60 minutes and more frequent than
weekly dosing have been shown to increase toxicity.
Pulmonary toxicity has been reported with the use of GEMZAR. In cases of
severe lung toxicity, GEMZAR therapy should be discontinued immediately and
appropriate supportive care measures instituted.
Hemolytic Uremic Syndrome (HUS) and/or renal failure have been reported
following one or more doses of GEMZAR. Renal failure leading to death or
requiring dialysis, despite discontinuation of therapy, has been rarely
reported. The majority of the cases of renal failure leading to death were due
Serious hepatotoxicity, including liver failure and death, has been
reported very rarely in patients receiving GEMZAR alone or in combination with
other potentially hepatotoxic drugs.
GEMZAR is Pregnancy Category D. GEMZAR can cause fetal harm when
administered to a pregnant woman.
Use caution in patients with pre-existing renal impairment or hepatic
insufficiency. Administration of GEMZAR may exacerbate underlying hepatic

The toxicities of GEMZAR observed in pediatric patients were similar to
those reported in adults.
GEMZAR clearance is affected by age as well as gender.
Patients receiving therapy with GEMZAR should be monitored closely by a
physician experienced in the use of cancer chemotherapeutic agents.
Monitoring and Dosage Modifications
Dosage adjustments for hematologic toxicity may be required.
Serum creatinine, potassium, calcium, and magnesium should be monitored
during combination therapy with cisplatin.
Patients should be assessed with a CBC, including differential and
platelet count, prior to each dose of GEMZAR. Modify or suspend therapy
according to the Dosage Reduction Guidelines in the full Prescribing
Hepatic and renal function (including transaminases and serum creatinine)
should be evaluated prior to therapy with GEMZAR and periodically thereafter.
