Trial Summary

What is the purpose of this trial?

This trial is testing siltuximab, a medication that blocks a protein called IL-6, to help reduce severe symptoms like weakness and fatigue after a stem cell transplant. The target group is patients aged 60-75 with multiple myeloma or systemic amyloidosis. By reducing inflammation, the goal is to improve recovery and shorten hospital stays.

Do I need to stop my current medications to join the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug Siltuximab for treating multiple myeloma?

Research shows that Siltuximab, when combined with other drugs like lenalidomide, bortezomib, and dexamethasone, resulted in a high response rate in newly diagnosed multiple myeloma patients, with 90.9% showing some level of positive response. Additionally, Siltuximab has been shown to enhance the effectiveness of melphalan, another drug used in treating multiple myeloma, by increasing cancer cell death in laboratory studies.12345

Is siltuximab generally safe for humans?

Siltuximab has been tested in various studies and is generally well tolerated in humans. Common side effects include skin itching, weight gain, rash, and upper respiratory infections, while serious side effects like pneumonia and low platelet counts have been observed in some cases. No deaths were reported in the studies reviewed.14678

How is the drug siltuximab unique in treating multiple myeloma?

Siltuximab is unique because it targets interleukin-6 (IL-6), a protein that plays a key role in the development of multiple myeloma, by using a monoclonal antibody to inhibit its activity. This approach is different from other treatments that may not specifically target IL-6, and it is administered intravenously every two weeks.12346

Treatment Details

Interventions

  • Siltuximab
  • The M.D. Anderson Symptom Inventory (MDASI)
Trial Overview The trial tests whether Siltuximab can reduce symptoms such as weakness and nausea after autologous stem cell transplantation by blocking a protein called Interleukin-6 (IL-6). Participants will receive Siltuximab before and after their transplant to see if it improves recovery and quality of life during the post-transplant period.

Findings from Research

In a study of 14 patients with newly diagnosed multiple myeloma, the combination of siltuximab with lenalidomide, bortezomib, and dexamethasone showed a high overall response rate of 90.9%, indicating strong efficacy in treating this condition.
The maximum tolerated dose of siltuximab was determined to be 8.3 mg/kg, with serious adverse events including grade 3 pneumonia and grade 4 thrombocytopenia, but no deaths occurred during the study, suggesting a manageable safety profile.

The IL-6-neutralizing monoclonal antibody siltuximab enhances the effectiveness of melphalan, a chemotherapy drug, against multiple myeloma cells, showing additive to synergistic effects in various human myeloma cell lines.
Siltuximab not only increases the cytotoxicity of melphalan but also promotes apoptosis through the activation of key caspases and suppression of the IL-6 signaling pathway, suggesting a promising combination therapy for patients with myeloma.
Blockade of interleukin-6 signalling with siltuximab enhances melphalan cytotoxicity in preclinical models of multiple myeloma.Hunsucker, SA., Magarotto, V., Kuhn, DJ., et al.[2021]
Siltuximab was approved by the FDA for treating multicentric Castleman disease (MCD) in HIV-negative and HHV-8-negative patients, based on a randomized trial with 79 patients showing a significant response rate; 34% of those treated with siltuximab achieved a durable tumor and symptomatic response compared to none in the placebo group.
The treatment was generally well-tolerated, with common side effects including pruritus, increased weight, rash, hyperuricemia, and upper respiratory tract infections occurring in more than 10% of patients.
