RESUMO

Twice-weekly carfilzomib (27 mg/m2) plus lenalidomide and dexamethasone (KRd27) is a standard-of-care in relapsed/refractory multiple myeloma (RRMM). Once-weekly carfilzomib regimens have shown clinical benefits with improved patient convenience. This open-label, phase 3, multicenter, randomized study aimed to demonstrate noninferiority of the overall response rate (ORR) for once-weekly carfilzomib (56 mg/m2) plus Rd (KRd56) vs twice-weekly KRd27 in RRMM. A total of 454 patients were randomized (1:1) to receive carfilzomib as once-weekly 30-minute infusions of 56 mg/m2 (KRd56; n=228) or twice-weekly 10-minute infusions of 27 mg/m2 (KRd27; n=226). Baseline characteristics were balanced between groups. ORR was 82.5% (95% confidence interval [CI], 76.9‒87.2) in the once-weekly group vs 86.3% (95% CI, 81.1‒90.5) in the twice-weekly group (risk ratio, 0.954 [95% CI, 0.882‒1.032]) and did not meet the threshold for statistical significance of noninferiority (P=0.0666). Complete response or better was obtained in 46.9% of patients in the once-weekly arm and 36.3% in the twice-weekly arm. The proportions of patients who achieved complete response and were also assessed negative for minimal residual disease were 21.5% and 18.1%, respectively (odds ratio, 1.235 [95% CI, 0.775‒1.970]). Progression-free survival was comparable between groups (hazard ratio, 0.945 [95% CI, 0.617‒1.447]). The safety profile was similar for both groups. In conclusion, although statistical significance for noninferiority of ORR was not achieved, the efficacy and safety of once-weekly KRd56 were similar to those of twice-weekly KRd27 and once-weekly KRd56 may be an effective and convenient treatment option for patients with RRMM. This trial was registered at www.clinicaltrials.gov as #NCT03859427.

RESUMO

PURPOSE: Mild-to-moderate bone pain is a commonly reported adverse event (AE) associated with pegfilgrastim. We evaluated the effect of prophylactic naproxen or loratadine vs no prophylactic treatment on pegfilgrastim-associated bone pain. METHODS: In this open-label study (NCT01712009), women ≥ 18 years of age with newly diagnosed stage I-III breast cancer and an ECOG performance status ≤ 2 who were planning ≥ 4 cycles of adjuvant or neoadjuvant chemotherapy with pegfilgrastim support starting in cycle 1 were randomized 1:1:1 to receive naproxen, loratadine, or no treatment to prevent pegfilgrastim-associated bone pain. The primary endpoint was all-grade bone pain in cycle 1 from AE reporting. Secondary endpoints included bone pain in cycles 2-4 and across all cycles from AE reporting and patient-reported bone pain by cycle and across all cycles. RESULTS: Six hundred patients were enrolled. Most patients (83.0%) were white, and mean (SD) age was 54.2 (11.1) years. The percentage of patients with all-grade bone pain in cycle 1 from AE reporting in the naproxen, loratadine, and no prophylaxis groups was 40.3, 42.5, and 46.6%, respectively; differences between the treatment groups were not statistically significant. Maximum, mean, and area under the curve for patient-reported bone pain were consistently lower in the naproxen and loratadine groups than in the no prophylaxis group; some of these differences were significant. Loratadine was associated with fewer treatment-related AEs and discontinuations than naproxen. CONCLUSIONS: Given its tolerability, its ease of administration, and its potential benefit, treatment with loratadine should be considered to help prevent bone pain in patients receiving chemotherapy and pegfilgrastim. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov ; NCT01712009.
