ABSTRACT
Aim: To evaluate the safety and effectiveness of carfilzomib in a real-world setting. Methods: A post-marketing surveillance of Japanese patients with relapsed or refractory multiple myeloma who received carfilzomib treatment was performed. Results: Overall incidences of adverse events of any grade, ≥grade 3 treatment-related adverse events and serious adverse events were 63.5, 44.6 and 37.7% of patients, respectively. No new safety findings were observed. Treatment-related adverse events of special interest (≥5%) were hematological toxicities, infectious disease, cardiac disorders (including cardiac failure, myocardial infarction and QT prolongation), renal disorders, liver failure or liver dysfunction, and hypertension or hypertensive crisis. The overall response rate was 46.5%. Conclusion: Carfilzomib was found to be a safe and effective treatment for relapsed or refractory multiple myeloma in Japanese patients.
Carfilzomib is a medicine that was recently approved for the treatment of cancer of bone marrow (multiple myeloma) that comes back or does not respond to previous treatment (relapsed or refractory). Data gathered from the hospitals, where the medicine is commonly used, was used to generate evidence. We looked at how well carfilzomib works in Japanese participants and if it is safe. Overall, 63.5% of participants treated with carfilzomib had side effects and 37.7% had serious side effects. Death occurred in 3.1% of participants during the study. Decrease in bone marrow and blood cells, infections, heart and kidney disorder, liver failure or dysfunction, and high blood pressure occurred in 5% or more participants. In 46.5% of participants the tumors had disappeared or shrank. In Japanese participants, carfilzomib was found to be safe and effective treatment for cancer of bone marrow that comes back or does not respond to previous treatment.

BACKGROUND: In Japan, intravenous digoxin was previously recommended as a standard drug for acute control of the heart rate in atrial fibrillation (AF)/atrial flutter (AFL) patients with chronic heart failure (CHF). Treatment alternatives for such cases were limited and new drugs for this purpose are needed. In November 2013, landiolol hydrochloride (Onoact(®) 50 for Injection, Ono Pharamaceutical, Osaka, Japan) was approved with the indication for "tachyarrhythmia (AF/AFL) in patients with cardiac dysfunction." However, clinical experience with this condition is still insufficient. Therefore, it is important to conduct a surveillance of landiolol under actual clinical settings. In addition, collecting data on the mid- and long-term outcomes in patients treated with landiolol which have not been collected in clinical trials are indispensable. METHODS: This prospective survey will involve patients treated with landiolol for the treatment of tachyarrhythmia (AF/AFL) in cardiac dysfunction at Japanese medical facilities from June 2014 to May 2017. The planned number of patients for analysis is approximately 500. The evaluations will be made not only to identify the adverse events and clinical effectiveness of the drug, but also to characterize the mid- and long-term outcomes of patients receiving and switching to oral-ß-blockers after the discontinuation of landiolol. RESULTS: This study was started in June 2014 (registration period 2 years, survey period 3 years) and will end in May 2017. CONCLUSIONS: This survey will clarify both the characteristics and mid- and long-term outcome of using landiolol to treat AF/AFL patients with cardiac dysfunction in clinical practice. Moreover, this survey will simultaneously provide important data that will reveal the possible gap between clinical trials and clinical practice in these patients.
