Background

Taxanes (docetaxel [DOC], CBZ) and androgen receptor-targeted therapies (ARTs; ABI, ENZ) are standard of care in mCRPC. The optimal treatment sequence is unknown. CARD (NCT02485691) compared CBZ vs ABI or ENZ in patients with mCRPC previously treated with DOC and the alternative ART.

Methods

Patients with mCRPC previously treated with ≥ 3 cycles of DOC and progressing ≤ 12 months (mo) on an alternative ART, in any order, were randomized 1:1 to CBZ (25 mg/m2 IV Q3W + prednisone + G-CSF) vs ABI (1000 mg PO + prednisone) or ENZ (160 mg PO). Randomization was stratified by ECOG PS (0/1 vs 2), time to progression on prior ART (≤ 6 vs 6–12 mo) and ART timing (before vs after DOC). Primary endpoint was radiographic PFS (rPFS), with 196 rPFS events needed to test HR 0.67 for CBZ (80% power, 2-sided alpha 0.05). Secondary efficacy endpoints and safety were assessed.

Results

Overall, 255 patients (median age 70, 31.0% ≥ 75 yrs) were randomized. Median number of cycles was higher for CBZ vs ART (7 vs 4). rPFS was significantly improved with CBZ vs ART (median 8.0 vs 3.7 mo; HR 0.54; 95% CI 0.40–0.73; p < 0.0001). CBZ also robustly improved OS (median 13.6 vs 11.0 mo; HR 0.64; 95% CI 0.46–0.89; p = 0.0078) despite crossover, as well as PFS (median 4.4 vs 2.7 mo; p < 0.0001), confirmed PSA50 response (35.7% vs 13.5%; p = 0.0002) and tumor response (36.5% vs 11.5%; p = 0.004). Pain response and time to symptomatic skeletal events were also significantly improved with CBZ. Grade ≥ 3 adverse events (AEs) occurred in 56.3% vs 52.4% of patients with CBZ vs ART. For CBZ vs ART, main grade ≥ 3 AEs were: renal disorders (3.2% vs 8.1%); infections (7.9% vs 7.3%); musculoskeletal pain/discomfort (1.6% vs 5.6%); cardiac disorders (0.8% vs 4.8%); spinal cord/nerve root disorders (2.4% vs 4.0%); asthenia/fatigue (4.0% vs 2.4%); diarrhea, peripheral neuropathy and febrile neutropenia (3.2% vs 0% for each). AEs led to death in 7 vs 14 patients (5.6% vs 11.3%) for CBZ vs ART.

Conclusions

CBZ significantly improved clinically important patient outcomes including rPFS and OS vs ART in patients with mCRPC previously treated with DOC and an alternative ART. CBZ should be the preferred option in this setting. Sanofi funded.
