Trial Information

A Phase II Study of Pemetrexed (Alimta) as Second-Line Therapy for Hormone Refractory Prostate Cancer: Hoosier Oncology Group GU03-67

OUTLINE: This is a multi-center study.

- Pemetrexed 500mg/m2 will be administered intravenously over approximately 10-minutes on
Day 1 of a 21-day cycle.

- Folic Acid (350-1000 mcg. PO daily) will be taken by patients to reduce toxicity. At
least 5 daily doses of folic acid must be taken during the 7-day period preceding the
first dose of pemetrexed, and dosing should continue during the full course of therapy
and for 21 days after the last dose of pemetrexed.

- Vitamin B12 (1000 µg) will be administered as an intramuscular injection during the
week preceding the first dose of pemetrexed and every 3 cycles thereafter. Subsequent
vitamin B12 injections may be given the same day as pemetrexed.

Performance Status: Karnofsky Performance Status 70-100

Life expectancy > 12 weeks


- ANC > 1500/mm3

- Platelet count > 100,000/mm3

- Hemoglobin > 9 g/dL


- Bilirubin < 1.5 X upper limit of normal (unless due to Gilbert's disease)

- Alkaline phosphatase and ALT (SGPT) < 3 X upper limit of normal; may be < 5 X ULN for
patients with liver metastases. Alkaline phosphatase may be any value for patients
with bone metastases.


- Calculated creatinine clearance >45 mL/min based on the standard Cockroft and Gault


- No congestive heart failure requiring therapy or NYHA class II or greater or active
angina or known myocardial infarction within 12 months prior to study

- No unstable angina, uncontrolled congestive heart failure, or unstable symptomatic
arrhythmia requiring medication within 6 months prior to being registered for protocol

- Subjects with chronic atrial arrhythmia, i.e., atrial fibrillation, paroxysmal
supraventricular tachycardia, or controlled hypertension are eligible


- Not specified

Inclusion Criteria:

- Histologically documented adenocarcinoma of the prostate

- Clinically refractory or resistant to hormone therapy as assessed by progression
following at least one hormonal therapy (orchiectomy or luteinizing hormone-releasing
hormone (LHRH) agonist)

- One prior taxane based chemotherapy regimen for HRPC

- Documented progression of disease after one taxane based prior chemotherapy regimen
for HRPC. Progression is defined as at least one of the following:

- An increase in PSA > 50% over nadir value on prior Taxane-based therapy

- Progression of measurable disease as defined by RECIST

- Progression of bone disease as defined by the appearance of one or more new bone
lesions or worsening symptoms

- Orchiectomy or testosterone levels < 50 ng/dL maintained by LHRH agonist

- Prior chemotherapy, or other experimental anticancer agents must be completed > 4
weeks prior to being registered for protocol therapy

- Palliative radiotherapy must be completed at least 14 days prior to registration.

Exclusion Criteria:

- Intravenous radio-isotopes therapy must be completed at least 6 weeks prior to

- No brain metastasis that are untreated and/or not controlled and/or still requiring

- No history of other malignancies within 5 years prior to being registered for
protocol therapy, except for adequately treated basal or squamous cell skin cancer

- No history of uncontrolled psychiatric illness or serious systemic disease, including
active infection, uncontrolled hypertension

- No surgery or significant traumatic injury within 21 days prior to being registered
for protocol therapy

- Patients must be willing to interrupt aspirin or other non-steroidal
anti-inflammatory agents for a 5-day period (8 day period for long acting agents such
as piroxicam)

- Patients must be willing to take folic acid or vitamin B12 supplementation
