What You Need to Know Before You Apply

What is the purpose of this trial?

This randomized phase III trial studies melphalan and prednisone with thalidomide to see how well it works compared to melphalan and prednisone together with lenalidomide in treating patients with newly diagnosed multiple myeloma. Drugs used in chemotherapy, such as melphalan and prednisone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Thalidomide and lenalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. It is not yet known whether melphalan and prednisone are more effective when given together with thalidomide or lenalidomide in treating multiple myeloma.

Do I have to stop taking my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you can continue taking bisphosphonates or growth factors like erythropoietin, although erythropoietin is discouraged due to increased risk of blood clots with thalidomide or lenalidomide.

Is the combination of Melphalan, Prednisone, and Lenalidomide/Thalidomide safe for treating multiple myeloma?

The combination of Melphalan, Prednisone, and Lenalidomide/Thalidomide has been used to treat multiple myeloma, but it can cause side effects like neutropenia (low white blood cell count), thrombocytopenia (low platelet count), and in rare cases, intrahepatic cholestasis (liver condition). While Lenalidomide is considered more effective and potentially less toxic than Thalidomide, it still requires careful monitoring for these side effects.12345

What makes the drug combination of Melphalan, Prednisone, Thalidomide, and Lenalidomide unique for treating multiple myeloma?

This drug combination is unique because it combines the standard treatment of melphalan and prednisone with thalidomide and lenalidomide, which are known for their immunomodulatory effects (they help the immune system fight cancer). Lenalidomide, a derivative of thalidomide, is considered more effective and potentially less toxic, offering a promising option for newly diagnosed multiple myeloma patients, especially those who are elderly.15678

What data supports the effectiveness of the drug combination Melphalan, Prednisone, and Lenalidomide for treating multiple myeloma?

Research shows that the combination of Melphalan, Prednisone, and Lenalidomide (MPR) has significant activity against multiple myeloma, especially in newly diagnosed patients. Lenalidomide, a key component, has been shown to improve outcomes when added to traditional treatments, although it may increase side effects.125910

Are You a Good Fit for This Trial?

This trial is for patients with newly diagnosed multiple myeloma. Eligible participants are those over 65 who declined alternative treatments, or adults under 65 not suitable for stem cell transplantation. They must have an ECOG performance status of <=2, no severe peripheral neuropathy, uncontrolled illnesses, active infections, or recent malignancies (with exceptions). Women of childbearing age must test negative for pregnancy and follow strict birth control measures.

What Are the Treatments Tested in This Trial?

Interventions

  • Lenalidomide
  • Melphalan
  • Prednisone
  • Thalidomide
Trial Overview The study compares two treatment combinations: melphalan and prednisone with thalidomide versus the same chemotherapy drugs with lenalidomide. The goal is to determine which combination better halts cancer growth by either killing cells or blocking blood flow to them. Participants will be randomly assigned to one of these treatment groups.

Published Research Related to This Trial

In a study of 54 newly diagnosed elderly multiple myeloma patients, the combination of melphalan, prednisone, and lenalidomide (MPR) resulted in a high response rate, with 81% of patients achieving at least a partial response and 23.8% achieving a complete response.
The treatment showed excellent safety profiles, with manageable hematologic adverse events, and a remarkable 1-year overall survival rate of 100%, indicating that MPR is a promising first-line therapy for this patient group.

The combination treatment of melphalan, prednisone, and lenalidomide (MPR) shows significant antimyeloma activity in newly diagnosed multiple myeloma patients, with a median progression-free survival of 28.5 months and a 2-year overall survival rate of 91%.
While MPR treatment resulted in manageable hematologic side effects, including grade 3/4 neutropenia in 52% of patients and grade 3/4 thrombocytopenia in 24%, no serious bleeding complications were reported, indicating that the regimen is relatively safe.

Lenalidomide has shown significant clinical activity in treating multiple myeloma, improving response rates to induction therapy to 85-95% in previously untreated patients, compared to older regimens that had response rates of only 45-55%.
Unlike thalidomide, lenalidomide aims to enhance efficacy while reducing side effects, making it a promising option for patients with newly diagnosed or relapsed multiple myeloma.
