Treanda May Enhance Response To Stem Cell Transplant In Myeloma Patients – Results from a Phase 1 clinical trial demonstrate the safety of adding Treanda (bendamustine) to melphalan (Alkeran) as high-dose therapy prior to stem cell transplantation. The researchers state that the side effects of Treanda-melphalan therapy were similar to those expected from melphalan alone. Of the 25 myeloma patients included in the study, the overall response rate was 79 percent, with 38 percent achieving a stringent complete response, 4 percent a complete response, 33 percent a very good partial response, and 4 percent a partial response. Treanda is approved in the United States as a treatment for chronic lymphocytic leukemia and certain lymphomas, and it is being investigated as a treatment for myeloma. It belongs to a class of drugs known as alkylating agents, which also includes melphalan and cyclophosphamide (Cytoxan). These drugs work by damaging the DNA of cancer cells, which in turn causes the cells to die.

Viracept May Overcome Velcade And Kyprolis Resistance In Multiple Myeloma – Findings from a recent preclinical study show that Viracept (nelfinavir) kills multiple myeloma cells, including those that are resistant to Velcade (bortezomib) and Kyprolis (carfilzomib). In addition, the researchers found that Viracept enhanced the effectiveness of Velcade and Kyprolis, particularly when administered to myeloma cells resistant to Velcade and Kyprolis. Viracept belongs to a class of drugs called protease inhibitors and was approved by the FDA to treat HIV in 1997. Viracept as well as Velcade and Kyprolis limit a cell’s ability to chop up and discard unwanted proteins. The accumulation of these unwanted proteins causes the cells to die. The researchers also investigated the anti-myeloma properties of eight other HIV protease inhibitors but found Viracept to be the most effective. The investigators therefore state that Viracept may be useful to overcome Velcade resistance and believe their results justify clinical study of Viracept in combination with Velcade or Kyprolis.

Pseudo-Autologous Stem Cell Transplant May Be Feasible Following Relapse After Donor Transplant – Canadian myeloma experts report that a 54-year-old myeloma patient is doing well, remains drug-free, but has a low level of monoclonal protein one year after undergoing a “pseudo-autologous stem cell transplant.” The patient was diagnosed with stage 2 myeloma in May 1997 and was treated with a donor (allogeneic) stem cell transplant, but she relapsed after 12 years. Her physicians then had her undergo a pseudo-autologous stem cell transplant, hoping that she would achieve a similarly long response to the second transplant while avoiding complications associated with a second donor transplant. An autologous transplant typically involves collecting a patient’s own stem cells prior to high-dose chemotherapy, and then reinfusing the stem cells into the patient after the chemotherapy. In this case, the patient’s bone marrow also was repopulated with stem cells from the patient herself, but those stem cells were no longer her own original stem cells. Instead, they were stem cells descended from the donor stem cells she received during her allogeneic transplant in 1997. Thus, this procedure is known as a “pseudo-autologous” transplant.

Tuesday was the final day of this year’s American Society of Hematology (ASH) meeting, which took place in Atlanta. The meeting concluded in the morning with a series of oral presentation sessions held simultaneously.
Three of the morning sessions focused on the biology of multiple myeloma as well as preclinical and clinical studies of treatment options for multiple myeloma patients.
This update will summarize the research presented during the session that focused on myeloma treatment options. In addition, it will summarize results from an important late-breaking study of pomalidomide that also was …

The National Comprehensive Cancer Network (NCCN) has updated its guidelines for the treatment of multiple myeloma, and the new guidelines will be interpreted by many as a vote of confidence for Revlimid maintenance therapy.
The NCCN guidelines are followed closely by physicians and by many U.S. health insurance companies, which frequently use them when making reimbursement decisions about different cancer treatments.
The guidelines are comprised of recommendations based on the results of recent clinical trials and ongoing scientific research. A panel of specialists within the myeloma field is responsible for updating the …

Results from a recent German study suggest that a combination of Revlimid, Treanda and prednisone is active and well tolerated in patients with relapsed or refractory multiple myeloma.
Findings from the Phase 1 trial were presented at the 17th Congress of the European Hematology Association (EHA) in Amsterdam last month.
A previous Phase 1 study showed that Treanda (bendamustine), in combination with Revlimid (lenalidomide) and dexamethasone (Decadron), is well tolerated and highly active in patients with relapsed or refractory myeloma (see related Beacon news).
Treanda, which already is …

Today was the third day of the American Society of Clinical Oncology (ASCO) annual meeting, and the morning was filled with oral presentations about important myeloma-related studies. Most of the talks were about potential new anti-myeloma drugs.
This update summarizes the presentations about panobinostat (Farydak), obatoclax, Treanda (bendamustine), and MLN9708 (ixazomib), which are all being developed as potential multiple myeloma treatments. In addition, the update includes a recap of a presentation about the safety of long-term bisphosphonate use.

Results of a small German study indicate that the combination regimen of Velcade, Treanda, and prednisone is effective and well tolerated in newly diagnosed multiple myeloma patients with kidney impairment.
The majority of patients showed improved kidney function after treatment. The study investigators point out that patients responded rapidly, which may have prevented the development of irreversible kidney failure.
Based on their findings, the investigators recommend that the combination therapy be investigated further in larger clinical trials.
Impaired kidney function is a severe complication of multiple myeloma and affects 20 percent to …

The 48th annual meeting of the American Society of Clinical Oncology (ASCO) will take place Friday, June 1, through Tuesday, June 5, in Chicago.
More than 25,000 clinical specialists from all over the world are expected to attend the five-day meeting to discuss the current research in cancer treatment and care. The theme for this year’s meeting is “Collaborating to Conquer Cancer.”
The meeting will include many presentations and seminars focused specifically on multiple myeloma. The ASCO website currently lists nearly 50 myeloma-based presentations (included under “lymphoma and plasma cell disorders”).
