Progressive Myeloma Responds to Monoclonal Antibody

More than 80% of patients with relapsed or refractory multiple myeloma responded to a monoclonal antibody against a cell surface protein expressed by almost all myeloma cells, results of a phase 2 clinical trial showed.

All patients received lenalidomide and dexa­methasone and were randomized to 10 or 20 mg of

The overall response rate included 92% of patients treated with 10 mg of elotuzumab and 73% of those who received 20 mg. After a median follow-up of 17.2 months, the median progression-free survival (PFS) had not been reached among patients in the 10-mg cohort, whereas patients assigned to 20 mg of elotuzumab had a median PFS of 18 months.

“These data are really encouraging when compared to those achieved with lenalidomide and high-dose dexamethasone,” Philippe Moreau, MD, a hematologic oncologist at Hotel-Dieu University Hospital in Nantes, France, said at the Annual Meeting of the American Society of Clinical Oncology.

An analysis limited to patients who had received only 1 prior regimen showed that all patients treated with the 10-mg dose of elotuzumab had objective responses, as did 82% of those who received the higher dose of the monoclonal antibody.

“[These results] indicate that this combination could also be effective in frontline treatment,” Moreau added.

Elotuzumab is a humanized monoclonal antibody that targets the CS1 glycoprotein expressed by more than 95% of myeloma cells. Normal cells express little or no CS1.

Moreau presented results of a trial involving 73 patients with previously treated multiple myeloma. A majority of the patients had received 2 or more prior regimens, and more than 60% of the patients had received lenalidomide and bortezomib.

The results showed that 33 of 36 patients in the 10-mg group had objective responses, including 5 complete responses. In the 20-mg arm, 30 of 37 patients responded to elotuzumab. Moreau reported that 48% of the entire study population had responses that met criteria for very good partial responses.

The most common grade 3/4 adverse events were neutropenia, lymphopenia, and thrombocytopenia, each of which occurred in 16% of patients.

Personalized Therapy in the Management of Myelodysplastic Syndromes (MDS)

At the 2012 conference of the Global Biomarkers Consortium, which took place March 9-11, 2012, in Orlando, Florida, Gautam Borthakur, MD, from The University of Texas MD Anderson Cancer Center in Houston, Texas, discussed the use of personalized therapy in the management of MDS. The myelodysplastic syndromes (MDS) are a [ Read More ]

Weightlifting in Women at Risk for Breast Cancer–Related Lymphedema

Although weightlifting reduced the need for lymphedema treatment by 50% compared with standard treatment in breast cancer survivors who participated in the Physical Activity Lymphedema (PAL) trial, weightlifting is not without its own risks. A retrospective analysis of the PAL trial found that the rate of injury was higher in [ Read More ]
