Sequencing of cabazitaxel in metastatic castrate-resistant prostate cancer: a case report.

ABSTRACT: Prostate cancer is a common cancer in men; for metastatic disease, it has a 5-year survival rate of 30%. No FDA-approved therapy for castrate-resistant prostate cancer (CRPC) known to improve survival was available until 2004, when based on a significant survival benefit over mitoxantrone, docetaxel in combination with prednisone was approved. In combination with prednisone, cabazitaxel, which was approved in the United States in 2010, is indicated for patients with metastatic CRPC previously treated with a docetaxel-containing regimen. This case report describes the treatment of a man 58 years of age who was diagnosed with advanced prostate cancer in 2006. He was initially managed with radical prostatectomy followed by androgen deprivation therapy, but a rising prostate-specific antigen (PSA) level led to enrollment in a clinical trial of HE3235 for 6 months. Subsequently, with progression of disease, he was treated with docetaxel for 4 months and then palliative radiation therapy. Cabazitaxel was initiated in October 2010; his condition stabilized within weeks, and he experienced a progressive decline in his PSA level from a peak of 5,424 ng/ml. Continued treatment with cabazitaxel resulted in his being weaned off pain medications and resuming his normal activities. After 16 cycles of cabazitaxel, his PSA declined to 994 ng/ml as of January 2012. He tolerated the cabazitaxel well and occasionally received myeloid growth factors for treatment of neutropenia; otherwise, he experienced only mild diarrhea. This response to cabazitaxel is notable, particularly in light of prior failure of multiple therapies.

Project description:ObjectivesTo assess cabazitaxel versus docetaxel re-challenge for the treatment of metastatic castrate refractory prostate cancer (CRPC) patients previously treated with docetaxel at inception of primary hormone therapy.Patients and methodsThe CANTATA trial was a prospective, two-arm, open-label, phase II study conducted in eight UK centres. Patients over the age of 18, with histologically proven, metastatic prostate cancer who had been previously treated with up to 6 cycles of docetaxel as part of the STAMPEDE trial (or treated with the same drug outside of the trial at primary diagnosis) and had a performance status (PS) of 0-2, were eligible. Patients who progressed during primary treatment with docetaxel or had received prior systemic chemotherapy were excluded. Cabazitaxel (25 mg/m2) or docetaxel (75 mg/m2) was administered via intravenous infusion every 3 weeks with oral prednisolone (10 mg) for up to 10 cycles, until disease progression, death or unacceptable toxicity. The primary outcome was clinical progression-free survival (PFS) as defined by either date of pain progression, date of a cancer-related skeletal-related event, or date of death from any cause. Analyses were by intention to treat. EudraCT number: 2012-003835-40.ResultsBetween 7 March 2013 and 4 January 2016, 15 patients with a median age of 70 years (range 54-76) were recruited; seven received cabazitaxel, eight docetaxel. The study was halted due to slow accrual. The median clinical PFS time in the cabazitaxel group was 6.2 months compared with 8.4 for the docetaxel group (95% confidence intervals were not reached due to the small number of patients). A total of 13 serious adverse events were reported.ConclusionDue to the low number of patients recruited, meaningful comparisons could not be made. However, toxicity was in line with known outcomes for these agents, demonstrating it is feasible and safe to deliver chemotherapy to men relapsing with CRPC after upfront chemotherapy.
