Carfilzomib (Kyprolis, Onyx Pharmaceuticals, South San Francisco, CA) is a proteasome inhibitor that recently received accelerated FDA approval as single-agent treatment for relapsed or refractory multiple myeloma (RRMM),1 as well as designation as a “Preferred Regimen” for salvage therapy according to the National Comprehensive Cancer Network (NCCN) guidelines.2 Carfilzomib differs structurally and mechanistically from bortezomib; it functions by irreversibly inhibiting chymotrypsin-like activity of the constitutive proteasome and the immunoproteasome and offers a novel treatment option for patients with advanced MM.3

Carfilzomib (Kyprolis, Onyx Pharmaceuticals, Inc, South San Francisco, CA) is a selective proteasome inhibitor that irreversibly binds to active sites within the proteolytic core of the 26S proteasome, resulting in inhibition of proteasome activity. Preclinical studies have shown carfilzomib inhibits tumor growth and promotes tumor cell death, with sustained proteasome inhibition for more than 48 hours when using a consecutive-day dosing regimen.1-4

The recent FDA approval of single-agent carfilzomib (Kyprolis) adds to the armamentarium of agents for the treatment of relapsed and refractory multiple myeloma. Carfilzomib was approved based on an open-label, single-arm study of single-agent carfilzomib after the failure of at least 2 previous therapies. Within the inclusion criteria, the subjects were required to have failed bortezomib. Although bortezomib and carfilz­omib are both proteasome inhibitors, carfilzomib selectively and irreversibly binds to its target, which results in sustained proteasome inhibition that is absent of off-target effects relative to bortezomib.1,2 Read More ›

ES has received 5 prior lines of therapy, with progression of disease documented on her most recent therapy with a rise in SPEP from 1.3 to 2.2 g/dL and in UPEP from 556 to 1342 mg/24 hours. The current clinical considerations include anemia, renal insufficiency, and PN grade 1 with pain.

Although the rates of bladder cancer incidence and bladder cancer deaths have been fairly stable over the past 20 years, the disease is still just as serious and deadly. In an effort to learn more about it, let’s take a closer look at bladder cancer, the fourth most common cancer diagnosed in men.

In 2012, an estimated 73,510 adults in the United States (55,600 men and 17,910 women) will be diagnosed with bladder cancer. Approximately 14,880 deaths (10,510 men and 4370 women) will occur from this disease.
