Overview
Brief Summary
The purpose of this study is to assess the efficacy, safety, tolerability, pharmacokinetics (PK), immunogenicity and efficacy of MP0250 in combination with bortezomib + dexamethasone in patients with refractory and relapsed multiple myeloma (RRMM).
MP0250 is a multi-DARPin® drug candidate with three specificities, able to simultaneously neutralize the activities of vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) and also to bind to human serum albumin (HSA) to give an increased plasma half-life and potentially enhanced tumor penetration.

Eligibility Criteria
Inclusion Criteria
- •Patients with MM who have received:
- •Part 1 ≥2 lines of therapy (including bortezomib and an IMiD) and have shown no response (i.e. stable disease) to, have progressed on the most recent treatment or have progressed within 60 days of the most recent therapy
- •Part 2 ≥2 lines of prior therapy that included a proteasome inhibitor (bortezomib, carfilzomib or both) and an IMiD (thalidomide, lenalidomide and/or pomalidomide) either alone or in combination and a response no better than SD lasting at least 4 months on a bortezomib- or carfilzomib-based regimen as last line of therapy or progression on treatment or within 60 days of stopping a bortezomib- or carfilzomib-based regimen as last line of therapy. Note: For transplant-eligible patients enrolled to Part 1 or Part 2, induction plus conditioning chemotherapy/ASCT +/- maintenance therapy constitute one regimen.
- •Presence of a measurable disease with at least one of the following criteria:
- •Serum M protein ≥0.5 g/dL, or
- •Urine M protein ≥200 mg/24 h, or
- •Involved serum free light chain (FLC) levels \>100 mg/L and abnormal kappa/lambda (κ/λ) ratio in patients without detectable serum or urine M protein, or
- •For patients with immunoglobulin A (IgA) myeloma whose disease can only be reliably measured by quantitative immunoglobulin measurement, a serum IgA level ≥0.5g/dL.
- •Eastern Cooperative Oncology Group (ECOG) performance status (0 to 1)
- •Life expectancy \>3 months
Exclusion Criteria
- •Patients with the following diseases:
- •Monoclonal gammopathy of undetermined significance (MGUS) of non- immunoglobulin (Ig)M and IgM subtypes,
- •Light chain MGUS,
- •Solitary plasmacytoma (alone or with minimal marrow involvement),
- •Systemic Ig light chain amyloidosis,
- •Waldenstrom's Macroglobulinemia,
- •Myelodysplastic syndrome,
- •Plasma cell leukemia defined as a plasma cell count \>2000/mm3
- •Polyneuropathy, organomegaly endocrinopathy, monoclonal protein, and skin changes (POEMS) syndrome
- •Peripheral neuropathy Grade 2 or higher at Screening or patients with a history of Grade 3/4 neuropathy or Grade 2 with pain
