Phase II Study Investigating the Efficacy and Activity of Single Agent Erlotinib in Chemotherapy-Naive Androgen Independent Prostate Cancer


This is a phase II open label single center study that evaluates the activity, efficacy, and
toxicity of single agent Tarceva in chemotherapy-naive AIPC patients. Patients will receive
single agent Tarceva at 150 mg daily without interruption until disease progression,
unacceptable toxicity, or investigator's discretion. Eligible patients are those with
documented prostate cancer (regardless of Gleason Score) who are considered hormone
refractory as defined below. All patients must fail an anti-androgen withdrawal trial if
they were already on such therapy. If patients were on LHRH analogues alone, they must fail
the addition of an anti-androgen before being classified as hormone refractory. All
patients must have adequate organ functions as specified below and have an ECOG performance
status of 2 or less. It is hypothesized that 25 patients will be needed to adequately
assess the activity of Tarceva in AIPC.

The activity of Tarceva in other malignancies has been demonstrated with dosed ranging from
100 to 150 mg daily. It is acceptable not to interrupt therapy unless toxicity occurs of
disease progression is documented. Starting patients at 150 mg daily seems to be the most
logical step, but dose reductions will be implemented based on side effects and adverse
events.


Inclusion Criteria:



- Documented prostate cancer regardless of Gleason score

- Patients should be considered hormone refractory and androgen independent. They must
fail LHRH analogues, and anti-androgen withdrawal trial.

- Failure is confirmed by an increase in PSA value of 10% or more than the value
immediately before, and confirmed by another assessment 2 weeks later.

- Patients have to have measurable disease either biochemically using rising PSA or/and
with metastatic disease to the bone or visceral organs.

- Performance status of 2 or less using ECOG scale.ยท Adequate liver function tests with
ALT/AST being < 3x normal, total bilirubin of 1.5 or less, and adequate renal
function measured by a creatinine of 2.0 mg/dl or less. Alkaline phosphatase values
are never exclusion criteria if it is deemed related to bone metastases.

- Patients need to have adequate bone marrow function. ANC of 1000 or above, Hgb of 9.0
g/dl or above, and platelets of 100,000 or above. If other causes are affecting plts
counts such as autoimmune disorders, patients are allowed on study.

- Patients with inadequate bone marrow function that is deemed related to bone marrow
involvement with prostate cancer are allowed at the investigator's discretion.

- Patients with other malignancies are allowed as long as there is no evidence of the
other malignancy present at entry time, and it has been 3 years or more since the
treatment for the other disorder was completed.

- Patients with prior exposure to investigational therapies including vaccines are
allowed on this study as long as their last exposure was 4 weeks prior to study
entry.Patients with known bone metastases are allowed to receive intravenous
bisphosphonates such as aredia or zometa.

- Patients on oral bisphosphonates are also allowed.

- Chemo Naive

Exclusion Criteria:

- Patients with prior exposure to Tarceva

- Patients who have received any prior systemic chemotherapy for prostate cancer.
Exposure to chemotherapy for other malignancies is allowed as long as last
chemotherapy was completed 3 years prior to study entry.

- Patients with prior malignancies are excluded except for those who have non-melanoma
skin cancers or other cancers that are in remission with the last therapy given 3
years prior to enrollment.

- Prior exposure to any form of steroids is allowed and is not considered exclusion
criteria.

- Performance status of 3 or above using ECOG scale.

- Known HIV positive status Known CNS involvement with prostate cancer
