About the PA33 study
The results of the double-blind, placebo-controlled Phase III
study conducted by the National Cancer Institute of Canada, Clinical
Trials Group at Queens University and involving 569 patients showed:
- Treatment
with Tarceva plus gemcitabine in patients with advanced pancreatic
cancer resulted in significantly improved overall survival compared
to gemcitabine alone (22%)
- 24% of
patients receiving Tarceva plus gemcitabine were alive after
one year, compared to 19% on gemcitabine alone
- Patients
receiving Tarceva plus gemcitabine experienced significantly
longer progression-free survival of 30%
- Tarceva
plus gemcitabine was well tolerated by patients
As a result
of this study, Tarceva plus gemcitabine has been approved for
the treatment of advanced pancreatic cancer in 15 countries including
America and Australia.
About Tarceva
Tarceva (erlotinib) is a small molecule that targets the human
epidermal growth factor receptor (HER1) pathway. HER1, also known
as EGFR, is a key component of this signalling pathway, which
plays a role in the formation and growth of numerous cancers.
Tarceva blocks tumour cell growth by inhibiting the tyrosine kinase
activity of the HER1 signalling pathway inside the cell.
Taken as an
oral, once-daily therapy, Tarceva is the only EGFR-inhibitor to
have demonstrated a survival benefit in lung cancer a very
impressive 42.5%. Currently most lung cancer patients are treated
with chemotherapy which can be very debilitating due to its toxic
nature. Tarceva works differently to chemotherapy by specifically
targeting tumour cells, and avoids the typical side-effects of
chemotherapy.
Tarceva is
approved in the US and across the European Union for patients
with locally advanced or metastatic non small cell lung cancer
(NSCLC) after failure of at least one prior chemotherapy regimen.
Tarceva has been approved by the FDA since November 2, 2005 for
treatment of locally advanced, inoperable, unresectable or metastatic
pancreatic cancer in combination with gemcitabine chemotherapy.
Tarceva is
currently being evaluated in an extensive clinical development
programme by a global alliance among OSI Pharmaceuticals, Genentech
and Roche, focussing on earlier stages of NSCLC. Additionally,
Tarceva is being studied in combination with Avastin in NSCLC.
Trials are also being conducted with Tarceva in other solid tumours,
such as ovarian, bronchioloalveolar (BAC), colorectal, pancreatic,
head and neck and glioma (brain).
