Patient Preference Between Cabazitaxel and Docetaxel in Metastatic Castrate-resistant Prostate Cancer

Overview[ - collapse ][ - ]

Purpose Taxotere is the current standard first-line chemotherapy for mCRPC and may be used as second-line therapy in good responders in first-line (Taxotere rechallenge). Jevtana has demonstrated a survival benefit versus mitoxantrone in patients progressing during or after Taxotere and is now the standard second-line chemotherapy. Taxotere and Jevtana have different toxicity profiles. Many patients who are receiving Jevtana for second-line treatment indicate they prefer this agent over Taxotere with regards to the general tolerance (namely peripheral neuropathy, nail changes, asthenia). This was not expected since Jevtana in post-Taxotere setting was associated with more grade 3-4 adverse events such as febrile neutropenia and diarrhea than Taxotere in first-line setting. The study design of CABA-DOC is similar to that of the PISCES trial which evaluated the patient preference between two standard treatments for first-line metastatic kidney cancer. Despite similar PFS improvements over placebo in phase III trials, results clearly showed that patients preferred pazopanib over sunitinib. A randomized phase III study is currently comparing the efficacy of Taxotere and Jevtana in first-line setting with overall survival as a primary end-point. Assessing patient preference between Jevtana and Taxotere would contribute to further identify differences between these two taxanes and clarify which one of these two taxanes should be used for second-line chemotherapy and perhaps for first-line chemotherapy in the future. Assessing patient preference between the two taxanes might be less biased in the first-line setting where patients have no previous experience with a taxane.

Current Primary Outcome MeasuresPatient preference [Time Frame: Assessed up 21 weeks after randomization] [Designated as safety issue: No]Patient preference (Taxotere versus Jevtana) assessed by a single question after completion of the second period of chemotherapy.
Primary outcome measure will be assessed in the intent-to-treat population as defined by all patients having completed the first 4 cycles without progression and having received at least 1 cycle of the second treatment period. Patients having progressed during the first period will discontinue the trial.

Brief Summary
Taxotere is the current standard first-line chemotherapy for mCRPC and may be used as
second-line therapy in good responders in first-line (Taxotere rechallenge). Jevtana has
demonstrated a survival benefit versus mitoxantrone in patients progressing during or after
Taxotere and is now the standard second-line chemotherapy. Taxotere and Jevtana have
different toxicity profiles.

Many patients who are receiving Jevtana for second-line treatment indicate they prefer this
agent over Taxotere with regards to the general tolerance (namely peripheral neuropathy,
nail changes, asthenia). This was not expected since Jevtana in post-Taxotere setting was
associated with more grade 3-4 adverse events such as febrile neutropenia and diarrhea than
Taxotere in first-line setting.

The study design of CABA-DOC is similar to that of the PISCES trial which evaluated the
patient preference between two standard treatments for first-line metastatic kidney cancer.
Despite similar PFS improvements over placebo in phase III trials, results clearly showed
that patients preferred pazopanib over sunitinib.

A randomized phase III study is currently comparing the efficacy of Taxotere and Jevtana in
first-line setting with overall survival as a primary end-point. Assessing patient
preference between Jevtana and Taxotere would contribute to further identify differences
between these two taxanes and clarify which one of these two taxanes should be used for
second-line chemotherapy and perhaps for first-line chemotherapy in the future.

Assessing patient preference between the two taxanes might be less biased in the first-line
setting where patients have no previous experience with a taxane.
