CHAARTED: ChemoHormonal Therapy Versus Androgen Ablation Randomized Trial for Extensive Disease in Prostate Cancer [CHAARTED]

new search

Trial Conditions
  • Prostate Cancer
What is the purpose of this trial?

RATIONALE: Androgens can cause the growth of prostate cancer cells. Androgen ablation therapy may stop the adrenal glands from making androgens. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether androgen-ablation therapy is more effective with or without docetaxel in treating metastatic prostate cancer. PURPOSE: This randomized phase III trial is studying androgen-ablation therapy and chemotherapy to see how well they work compared to androgen-ablation therapy alone in treating patients with metastatic prostate cancer.

progression from its lowest point between the start of androgen-deprivation
therapy and randomization

PATIENT CHARACTERISTICS:

- ECOG performance status (PS) 0-2

- PTT ≤ 1.5 times ULN (unless on therapeutic anticoagulation)

- No prior malignancy in the past 5 years except for basal cell or squamous cell
carcinoma of the skin

- Other malignancies that are considered to have low potential to progress (e.g.,
grade 2, T1a transitional cell carcinoma) may be allowed if approved by study
chair

- No peripheral neuropathy > grade 1

- No history of severe hypersensitivity reaction to docetaxel or other drugs formulated
with polysorbate 80

- Fertile patients must use effective contraception

PRIOR CONCURRENT THERAPY:

- See Disease Characteristics

- At least 4 weeks since prior major surgery and recovered from all toxicity prior to
randomization

- Prior adjuvant or neoadjuvant hormonal therapy allowed provided the following are
true:

- Therapy was discontinued ≥ 12 months ago AND there is no evidence of disease, as
defined by 1 of the following:

- PSA < 0.1 ng/dL after prostatectomy plus hormonal therapy

- PSA < 0.5 ng/dL and has not doubled above nadir after radiotherapy plus
hormonal therapy

- Therapy lasted no more than 24 months

- Last depot injection must have expired by the 24-month mark

- Prior palliative radiotherapy allowed if commenced within 30 days before starting
androgen deprivation

- Anti-androgen therapy allowed as single-agent therapy ≤ 7 days before medial
castration to prevent flare

- No prior chemotherapy in adjuvant or neoadjuvant setting

- No prior hormone therapy in the metastatic setting

- More than 30 days (or 6 half-lives) (whichever is longer) since prior participation
in another clinical trial

- Patients can not simultaneously enroll on CALGB 90202

- Concurrent participation in nontherapeutic trials allowed

- Concurrent antiandrogen therapy (e.g., bicalutamide or flutamide) allowed, but not as
sole hormonal therapy

- No concurrent 5-alpha reductase inhibitors
