Definition of Relapsed/Refractory Disease

1. ‘Relapsed’ disease: first progression in the absence of any therapy– Biochemical relapse

– Symptomatic relapse

2. ‘Relapsed and Refractory’: progression on specific therapy or within 60 days of completion of a given therapy– Refractory to bortezomib and/or lenalidomide

3. ‘Primary Refractory’: no response following initial induction therapy

Factors in selecting treatment for relapsed/refractory myeloma

1. Disease‐related factors– Duration of response to initial therapy– FISH or cytogenetic profile (e.g. t(4;14) or p53 deletion)

2. Regimen‐related– Prior drug exposure (relapsed vs refractory)– Toxicity of regimen (combination vs single agent)– Mode of administration (e.g., oral, sq, IV)– Previous transplant‐durability of response after transplant

3. Patient‐related factors– Pre‐existing toxicities (e.g., cumulative myelosuppression, peripheral 

neuropathy)– Co‐morbid conditions (e.g., renal failure, diabetes mellitus)– Age– Performance status– Distance from Center– Insurance

• Elotuzumab (HuLuc63) is a humanized monoclonal IgG1 antibody targeting human CS1, a cell surface glycoprotein

• CS1 is highly and uniformly expressed on MM cells

– Restricted expression on NK cells

– Little to no expression on normal tissues

Elotuzumab

• Monoclonal antibody targeting cell surface protein CS1

• Demonstrated activity in relapsed/refractory myeloma when given in combination Bortezomib and Lenalidomide

• Preliminary results from the Lenalidomide‐dex study showed an overall response rate of 82%

• The most common side effects seen with elotuzumab are infusion reactions. 

• Being evaluated in combination with Revlimid‐low‐dose‐dexin two Phase III trials. One study is in relapsed or refractory myeloma, the other is in newly diagnosed disease. ELOQUENT‐1 and ELOQUENT‐2

Conclusion 

1. Many treatment options available at time of relapse2. When selecting  salvage therapy take in consideration:

Disease‐related factorsRegimen‐related

– Prior drug exposure (relapsed vs refractory)– Toxicity of regimen– Mode of administration– Previous transplant

Patient‐related factors– Pre‐existing toxicities– Co‐morbid conditions– Age– Performance status– Distance from Center– Insurance
