The objective of the study was to evaluate the safety, pharmacokinetics, and antitumor activity of ispinesib, a kinesin spindle protein inhibitor. Patients with locally advanced or metastatic breast cancer who had received only prior neoadjuvant or adjuvant chemotherapy were treated with escalating doses of ispinesib administered as a 1-h infusion on days 1 and 15 every 28 days until toxicity or progression of disease. Doses were escalated until dose-limiting toxicity was observed in two out of six patients during cycle 1. A total of 16 patients were treated at three dose levels: 10 mg/m (n=3), 12 mg/m (n=6), and 14 mg/m (n=7). Forty-four percent of the patients had locally advanced disease and 56% had metastatic disease; 50% were estrogen receptor positive, 44% were progesterone receptor positive, 25% human epidermal growth factor 2 were positive, and 31% triple (estrogen receptor, progesterone receptor, human epidermal growth factor 2) negative. Sixty-nine percent of patients were chemo-naive. The maximum tolerated dose was 12 mg/m and dose-limiting toxicity was grade 3 increased aspartate aminotransferase and alanine aminotransferase. The most common toxicities included neutropenia (88%; 38% grade 3 and 44% grade 4), increased alanine aminotransferase (56%), anemia (38%), increased aspartate aminotransferase (31%), and diarrhea (31%). No neuropathy, mucositis, or alopecia was reported. Among the 15 patients evaluable for antitumor activity, there were three partial responses, one confirmed by the response evaluation criteria in solid tumors (7% response rate). Nine patients (60%) had stable disease lasting at least 42 days, with four (27%) lasting for at least 90 days. Disease stabilization (partial responses+stable disease) was observed in 11 (73.3%) patients. In conclusion, ispinesib was well tolerated when administered on days 1 and 15 every 28 days. Limited activity was observed with this schedule in patients with previously untreated advanced breast cancer.

Multiple myeloma (MM) is a disease that affects plasma cells and can lead to devastating clinical features such as anemia, lytic bone lesions, hypercalcemia, and renal disease. An enhanced understanding of MM disease mechanisms has led to new more targeted treatments. There is now a plethora of treatments available for MM. In this review article, our aim is to discuss many of the novel agents that are being studied or have recently been approved for the treatment of MM. These agents include the following: immunomodulators (pomalidomide), proteasome inhibitors (carfilzomib, marizomib, ixazomib, oprozomib), alkylating agents (bendamustine), AKT inhibitors (afuresertib), BTK inhibitors (ibrutinib), CDK inhibitors (dinaciclib), histone deacetylase inhibitors (panobinostat, rocilinostat, vorinostat), IL-6 inhibitors (siltuximab), kinesin spindle protein inhibitors (filanesib), monoclonal antibodies (daratumumab, elotuzumab, indatuximab, SAR650984), and phosphoinositide 3-kinase (PI3K) inhibitors.
