PURPOSE Patients with triple-negative breast cancer (TNBC) and residual invasive disease (RD) after completion of neoadjuvant chemotherapy (NAC) have a high-risk for recurrence, which is reduced by adjuvant capecitabine. Preclinical models support the use of platinum agents in the TNBC basal subtype. The EA1131 trial hypothesized that invasive disease-free survival (iDFS) would not be inferior but improved in patients with basal subtype TNBC treated with adjuvant platinum compared with capecitabine. PATIENTS AND METHODS Patients with clinical stage II or III TNBC with ≥ 1 cm RD in the breast post-NAC were randomly assigned to receive platinum (carboplatin or cisplatin) once every 3 weeks for four cycles or capecitabine 14 out of 21 days every 3 weeks for six cycles. TNBC subtype (basal v nonbasal) was determined by PAM50 in the residual disease. A noninferiority design with superiority alternative was chosen, assuming a 4-year iDFS of 67% with capecitabine. RESULTS Four hundred ten of planned 775 participants were randomly assigned to platinum or capecitabine between 2015 and 2021. After median follow-up of 20 months and 120 iDFS events (61% of full information) in the 308 (78%) patients with basal subtype TNBC, the 3-year iDFS for platinum was 42% (95% CI, 30 to 53) versus 49% (95% CI, 39 to 59) for capecitabine. Grade 3 and 4 toxicities were more common with platinum agents. The Data and Safety Monitoring Committee recommended stopping the trial as it was unlikely that further follow-up would show noninferiority or superiority of platinum. CONCLUSION Platinum agents do not improve outcomes in patients with basal subtype TNBC RD post-NAC and are associated with more severe toxicity when compared with capecitabine. Participants had a lower than expected 3-year iDFS regardless of study treatment, highlighting the need for better therapies in this high-risk population.
BACKGROUND Red blood cell (RBC) transfusion is an important treatment modality during severe sickle cell crisis (SCC). SCC patients who refuse, or cannot accept, RBCs present a unique challenge. Acellular hemoglobin (Hb)‐based oxygen carriers (HBOCs) might be an alternative for critically ill patients in SCC with multiorgan failure due to life‐threatening anemia. HBOC‐201 (HbO2 Therapeutics) has been administered to more than 800 anemic patients in 22 clinical trials, but use of any HBOCs in critically ill sickle cell patients with organ failure is exceedingly rare. In the United States, HBOC‐201 is currently only available for expanded access. CASE REPORT We report three cases of HBOC‐201 administered to critically ill sickle cell disease patients in SCC with multiorgan failure, either who refused RBCs (Jehovah's Witnesses) or for whom compatible RBCs were not available. RESULTS Two patients received more than 20 units of HBOC‐201, while the other received 6. The 27 units used in the third case equals the largest volume a patient has successfully received to date. All three patients survived to hospital discharge. CONCLUSION These reports suggest that blood substitutes such as HBOC‐201 can provide an oxygen bridge in SCC with multiorgan failure, until corpuscular Hb levels recover to meet metabolic demand, and highlight the compelling biochemical properties that warrant further investigation.
To our knowledge, this trial is one of the first clinical investigations of short chain ceramides. This trial's results are not promising enough to merit further study of ceramides in the manner prescribed.
IMPORTANCE Elevated expression of AURKA adversely affects prognosis in estrogen receptor (ER)-positive and ERBB2 (formerly HER2)-negative and triple-negative breast cancer and is associated with resistance to taxanes. OBJECTIVE To compare paclitaxel alone vs paclitaxel plus alisertib in patients with ER-positive and ERBB2-negative or triple-negative metastatic breast cancer (MBC). DESIGN, SETTING, AND PARTICIPANTSIn this randomized clinical trial conducted with the US Oncology Network, participants were randomized to intravenous (IV) paclitaxel 90 mg/m 2 on days 1, 8, and 15 on a 28-day cycle or IV paclitaxel 60 mg/m 2 on days 1, 8, and 15 plus oral alisertib 40 mg twice daily on days 1 to 3, 8 to 10, and 15 to 17 on a 28-day cycle. Stratification was by prior neo or adjuvant taxane and by line of metastatic therapy. Eligible patients were those who had undergone endocrine therapy, 0 or 1 prior chemotherapy regimens for MBC, more than 12 months treatmentfree interval from neo or adjuvant taxane therapy, and with measurable or evaluable lytic bonedisease. Data were analyzed from March 2019 through May 2019. MAIN OUTCOMES AND MEASURES The main outcome was progression-free survival (PFS) with secondary end points of overall survival (OS), overall response rate, clinical benefit rate, safety, and analysis of archival breast cancer tissues for molecular markers associated with benefit from alisertib. RESULTS A total of 174 patients were randomized, including with 86 randomized to paclitaxel and 88 patients randomized to paclitaxel plus alisertib, and 169 patients received study treatment. The final cohort included 139 patients with a median (interquartile range [IQR]) age of 62 (27-84) years with ER-positive and ERBB2-negative MBC, with 70 randomized to paclitaxel and 69 randomized to paclitaxel plus alisertib. The TNBC cohort closed with only 35 patients enrolled due to slow accrual and were not included in efficacy analyses. The median (IQR) follow-up was 22 (10.6-25.1) months, and median (IQR) PFS was 10.2 (3.8-15.7) months with paclitaxel plus alisertib vs 7.1 (3.8-10.6) monthswith paclitaxel alone (HR, 0.56; 95% CI, 0.37-0.84; P = .005). Median (IQR) OS was 26.3 (12.4-37.2) months for patients who received paclitaxel plus alisertib vs 25.1 (11.0-31.4) months for paclitaxel alone (HR, 0.89; 95% CI, 0.58-1.38; P = .61). Grade 3 or 4 adverse events occurred in 56 patients (84.8%) receiving paclitaxel plus alisertib vs 34 patients (48.6%) receiving paclitaxel alone. The main grade 3 or 4 adverse events with paclitaxel plus alisertib vs paclitaxel alone were neutropenia (50 patients [59.5%] vs 14 patients [16.4%]), anemia (8 patients [9.5%] vs 1 patient [1.2%]), diarrhea (9 patients [10.7%] vs 0 patients), and stomatitis or oral mucositis (13 patients [15.5%] vs 0 patients).One patient receiving paclitaxel plus alisertib died of sepsis.
