Trial Information

A Phase II Trial of 17-Allylamino-17-Demethoxygeldanamycin (17-AAG) in Patients With Hormone-Refractory Metastatic Prostate Cancer


I. Determine the prostate-specific antigen (PSA) response in patients with
hormone-refractory metastatic prostate cancer treated with
17-N-allylamino-17-demethoxygeldanamycin (17-AAG).


I. Determine the overall survival and disease-free survival rate in patients treated with
this drug.

II. Determine the safety profile of this drug in these patients. III. Determine the duration
of PSA response and PSA control in patients treated with this drug.

IV. Determine the partial and complete response rates in patients with measurable disease
treated with this drug.

V. Correlate changes in expression levels of interleukin-6, maspin, and NF-kappaB in serum
and tissue with cancer and treatment-related outcomes in patients treated with this drug.

OUTLINE: This is a multicenter study. Patients receive
17-N-allylamino-17-demethoxygeldanamycin (17-AAG) IV over 2-6 hours on days 1, 8, and 15.
Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Patients who achieve a complete response (CR) receive 2 additional courses of treatment
beyond documentation of CR.

After completion of study treatment, patients are followed every 3 months for 1 year and
then every 6 months for 3 years.

PROJECTED ACCRUAL: A total of 16-28 patients will be accrued for this study within 20

Inclusion Criteria:

- Creatinine clearance ≥ 60 mL/min

- Creatinine normal

- QTc < 450 msec for male patients

- LVEF > 40% by MUGA

- EF normal by MUGA if prior anthracycline therapy

- No congenital long QT syndrome

- No left bundle branch block

- Deep venous thrombosis or other clinically significant thromboembolic event within
the past 6 months allowed provided patient is clinically stable on anticoagulation

- No poorly controlled angina

- No uncontrolled dysrhythmia or dysrhythmias requiring medication

- No active ischemic heart disease within the past 12 months

- No other significant cardiac disease

- Pulmonary embolus allowed within the past 6 months provided patient is clinically
stable on anticoagulation therapy

- Fertile patients must use effective contraception

- Willing and able to provide blood samples

- No serious allergy (i.e., hypotension, dyspnea, anaphylaxis, or edema) to eggs

- No other concurrent malignancy or history of a curatively treated malignancy with a
survival prognosis of < 5 years

- No known HIV positivity

- No active infection

- No other severe acute or chronic medical or psychiatric condition or laboratory
abnormality that would preclude study participation
