Extended Use Of Revlimid Plus Dexamethasone Delays Progression Of Relapsed / Refractory Myeloma

Results from a recent retrospective study conducted in France indicate that long-term treat­ment with Revlimid plus dex­a­meth­a­sone is effective in delaying dis­ease progression in relapsed multiple myeloma patients.

Among patients treated with Revlimid (lenalidomide) plus dex­a­meth­a­sone (Dec­a­dron) for at least two years, almost all (96 percent) responded to treat­ment, with 74 percent achieving at least a very good partial re­sponse.

Patients who received treat­ment for at least three years were significantly more likely to have not yet progressed 37 months after beginning treat­ment (91 percent), compared to …

Doxil With Revlimid And Dexamethasone Falls Short As Therapy For Newly Diagnosed Myeloma

Researchers from the Moffitt Cancer Center recently published results from a Phase 2 clinical trial that investigated the combination of Revlimid plus Doxil and low-dose dexa­metha­sone as initial therapy for patients with newly diag­nosed multiple myeloma.

Although the results show an overall re­sponse rate of 77 per­cent, a medi­an progression-free survival time of 28 months, and a one-year overall survival rate of 98 per­cent for the Revlimid (lenalidomide), Doxil (doxo­ru­bi­cin liposomal), and dexa­metha­sone (Decadron) combination, the re­search­ers indicate that this combination is not an …

Kyprolis-Revlimid-Dexamethasone Combination Continues To Show Promise For Relapsed Myeloma

Results from a recent Phase 2 trial indicate that the combination of Kyprolis, Revlimid, and dexamethasone is effective in relapsed multi­ple myeloma patients.

Specifically, the results show that 77 percent of patients responded to the treat­ment. The investigators point out the responses seen in the trial were rapid (median time to response was one month) and robust (medi­an duration of response was 22 months).

According to the investigators, the results are particularly encouraging because one-quarter of the patients were refractory (resistant) to Velcade (bortezomib) and almost half were …

Aspirin Not As Effective As Other Agents In Preventing Blood Clots During Myeloma Treatment With Thalidomide Or Revlimid

Results from a recent French study based on data from clinical practice indicate that vitamin K antagonists and low-molecular weight heparin are more effective than aspirin in preventing clots during myeloma treatment with the immuno­modu­la­tory drugs thalidomide or Revlimid.

Specifically, 7 percent of patients receiving aspirin developed blood clots, compared to 3 percent of patients receiving low-molecular weight heparin and 0 percent receiving a vitamin K antagonist such as warfarin (Coumadin).

Interestingly, the rate of blood clot formation was lowest among patients with the highest risk of developing blood clots, …

Reovirus Strain Shows Promise As An Anti-Myeloma Agent In Preclinical Study – Canadian researchers recently found that a specific strain of the reovirus may be an effective therapy for depleting residual multiple myeloma cells from stem cells collected for stem cell trans­planta­tion. Specifically, the researchers found that the virus was able to kill multiple myeloma cells in human stem cell samples without affecting the healthy blood stem cells.  The researchers took human stem cell samples, added multiple myeloma cells to get a tumor burden of 2 percent to 6 percent, incubated the samples with either live or dead reovirus, and trans­planted the stem cells into immuno­com­pro­mised mice.  All of the mice trans­planted with stem cells incubated with the dead virus developed myeloma, while none of the mice trans­planted with stem cells incubated with the live virus showed any signs of multiple myeloma. Reoviruses are typically found in the lungs and gastrointestinal tracts of animals.  Many are not associated with any known illness.  Previous studies have found that reovirus strains can selectively target and destroy cancer cells, while simultaneously triggering an immune response that helps destroy additional cancer cells. The reovirus strain tested in the Canadian study, reovirus serotype 3 (strain Dearing), also goes by the brand name Reolysin.  It is under development by the company Oncolytics Biotech, and is currently being studied in a Phase 1 clinical trial as a monotherapy for relapsed or refractory multiple myeloma.  For more in­for­ma­tion, please refer to the study in the journal Bone Marrow trans­plantation (abstract).

CD44 May Be A Good Indicator Of Revlimid Resistance In Myeloma – Findings from a recent preclinical study conducted at M. D. Anderson indicate that the protein CD44 may be a good marker of Revlimid (lena­lidomide) resistance in multiple myeloma. In particular, the researchers found that Revlimid-resistant myeloma cells had significantly higher levels of CD44 compared to Revlimid-sensitive myeloma cells. CD44 is a protein that is involved in keeping cells attached to tissue; myeloma cells high in CD44 bind to bone marrow tissue, thereby resisting treatment with Revlimid. Another marker for Revlimid-resistance that has been recently discovered is cereblon; myeloma cells with low levels of cereblon do not respond to treatment with Revlimid (see related Beacon news). The M.D. Anderson researchers also found that the leukemia drug tretinoin (all-trans retinoic acid, Vesanoid) was able to reduce the amount of CD44 in myeloma cells and re-sensitized myeloma cells to Revlimid therapy in both human and mice samples. Based on the findings, the investigators believe that a combination of tretinoin and Revlimid may be effective in Revlimid-resistant patients. For more information, please refer to the study in the journal Leukemia (abstract).

Snake Venom Shows Anti-Myeloma Activity – Results from a recent preclinical study conducted in the Middle East show that venom from the desert black snake, also known as the desert cobra or desert python, may have anti-myeloma activity. The snake venom was administered by itself or inside of nanoparticles, which are extremely small objects that can deliver drugs to specific cells in the body. The researchers found that, in mice with multiple myeloma, the anti-myeloma effect of the snake venom was greater when delivered inside of nanoparticles. Previous preclinical studies have shown that snake venom also may be effective in treating solid tumors, such as breast, colon, and prostate cancer.
