Study of Single Agent Lenalidomide in Older Adults With Newly Diagnosed Multiple Myeloma

Phase II Study of Response Adapted Therapy Using Single Agent Lenalidomide in Older Adults With Newly Diagnosed, Standard Risk Multiple Myeloma

The purpose of this research is to estimate the effectiveness of a response adapted approach with the use of the drug, lenalidomide in the treatment of older adults with newly diagnosed standard risk multiple myeloma. This means that participants will be given the study drug, lenalidomide but depending on how they respond to this drug they may also be given dexamethasone and/or prednisone to help with their treatment.

Study Overview

• Status: Completed
• Conditions: Multiple Myeloma
• Intervention / Treatment: Drug: Lenalidomide; Drug: Prednisone; Drug: Dexamethasone

Detailed Description

Summary: Patients will be started on the study drug, lenalidomide on Day 1, Cycle 1. Lenalidomide is a capsule that is to be taken orally (by mouth). If the patient's disease progresses after 2 cycles of therapy, a low dose of dexamethasone will be added. If the patient's disease is stable after 2 cycles of therapy, the use of an alternate corticosteroid (prednisone) will be added to the lenalidomide therapy they are receiving. Dexamethasone and prednisone are in tablet form and will be taken orally (by mouth). However, if the patient has a minimal response after an additional 2 cycles of lenalidomide therapy, the therapy will be continued until their disease progresses. See the intervention descriptions for further details.

FCBP must also agree to ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact with a female of child bearing potential even if they have had a successful vasectomy.

Exclusion Criteria:

• Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form
• Pregnant or lactating
• Any condition, including the presence of laboratory abnormalities, which places the patient at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Combined Therapy - Median Progression Free Survival	Progression free survival (PFS) of older adults with mildly symptomatic multiple myeloma treated on this response adapted approach (i.e. time from start of lenalidomide to failure of lenalidomide and low dose dexamethasone)	up to 36 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Response Rate	Response rate in older adults with mildly symptomatic multiple myeloma to single agent lenalidomide, lenalidomide prednisone and lenalidomide low dose dexamethasone in patients with suboptimal responses to lenalidomide monotherapy. The study used the uniform response assessment of the International Myeloma Working Group with the addition of MR (minimal response) (Durie et al, 2006; Kumar et al, 2016). MR was defined as a 25-49% decrease in serum M spike, and a 50-89% improvement in urine M spike. For patients without a measurable serum or urine M spike, a 25-49% decrease in the difference between the involved and uninvolved free light chains was required. The response in this trial is defined as complete remission (CR), stringent complete remission (SRC), very good partial remission (VGPR) and partial remission (PR) and minimal response (MR).	Every 8 weeks up to 12 months
Number of Participants With Serious Adverse Events	Number of participants with serious adverse events	Day 1 through Off Study Date, an average of 48 months
Single Agent - Median Progressive Free Survival (PFS)	The progression free survival of patients treated with single agent lenalidomide	First measure at 8 weeks
Number of Participants With 1 Year Overall Survival (OS)	The 1 year overall survival of older adults with mildly symptomatic multiple myeloma treated on this response adapted approach	1 Year
