A Trial Evaluating Efficacy & Safety of RVD +/- Panobinostat in Transplant Eligible, Newly Diagnosed Multiple Myeloma (NDMM)

• Status: Terminated
• Trial end date: 2017-05-22
• Target enrollment: 0
• Participant gender: All

Summary

This was a multicenter, open-label, randomized phase II study which were to enroll 112 newly diagnosed symptomatic multiple myeloma patients in a 1:1 fashion. Patients were to enroll at approximately 20 centers in the United States.

Patients were to undergo stem cell mobilization with plerixafor plus Granulocyte Colony Stimulating Factor (G-CSF), according to investigator discretion, after 4 cycles of induction therapy. Study treatment interruption for stem cell collection were not to exceed 30 days. All patients were to receive one additional cycle of study treatment after stem cell collection and then proceed to autologous transplant using melphalan 200mg/m2(140mg/m2 for patients > 70 years), as conditioning.

After Autologus Stem Cell Transplant( ASCT), patients still on study were to initiate maintenance therapy within the 60-120 day period following ASCT, provided they have adequate blood count and clinical recovery. Patients in the RVD arm were to initiate maintenance therapy with lenalidomide alone, and patients in RVD-panobinostat arm were to receive lenalidomide + panobinostat maintenance. Lenalidomide were to be dosed orally at 10mg/day continuously in both arms, increasing to 15mg/day after the first 84 day cycle. Panobinostat were to be dosed at 10mg three times a week, every other week. Total planned duration of maintenance therapy were to be 3 years.

Patients were to remain on study treatment until they complete the maintenance phase, or until they experience disease progression, unacceptable toxicity, or at the discretion of the Investigator.

Key Exclusion Criteria:

Patients eligible for this study must not meet any of the following criteria:

• Patient with rade ≥ 2 peripheral neuropathy or grade 1 peripheral neuropathy with pain on clinical examination at screening

• Patient received prior treatment with DAC inhibitors including Panobinostat

• Patient needing valproic acid for any medical condition during the study or within 5 days prior to first administration of panobinostat/study treatment.

• Patient taking any anti-cancer therapy concomitantly (bisphosphonates are permitted only if commenced prior to the start of screening period)

• Patient who received:

1. prior anti-myeloma chemotherapy or medication including Immunomodulator (IMiDs) and Dex ≤ 3 weeks prior to start of study.

2. experimental therapy or biologic immunotherapy including monoclonal antibodies ≤ 4 weeks prior to start of study.

3. prior radiation therapy ≤ 4 weeks or limited field radiotherapy ≤ 2 weeks prior start of study.

• Patient has not recovered from all therapy-related toxicities associated with above listed treatments to < grade 2 CTCAE.

• Patient undergone major surgery ≤ 2 weeks prior to starting study drug or who have not recovered from side effects of such therapy to < grade 2 CTCAE

• Patients with evidence of mucosal or internal bleeding

• Clinically significant, uncontrolled heart disease and/or recent cardiac event (within 6 month prior to screening)

• Inability to determine the Fridericia's Correction Formula (QTc) F interval
