Outcome measures
Primary outcome
Part A:
Primary objective
- To determine which regimen of nivolumab with daratumumab (either with or
without low dose cyclophosphamide) merits further evaluation in MM patients
with previous exposure to proteasome inhibitor and lenalidomide-resistant
disease, based on safety and efficacy data
Part B
Primary objective
- To investigate the efficacy of nivolumab combined with daratumumab with or
without low dose cyclophosphamide, as determined by the (s)CR+VGPR+PR rate.
Secondary outcome
Part A:
Secondary objective
- Evaluate the safety of nivolumab-daratumumab with or without low dose
cyclophosphamide in MM patients with previous exposure to proteasome inhibitor
and lenalidomide-refractory disease
- Evaluate the preliminary efficacy of nivolumab-daratumumab with or without
low dose cyclophosphamide in MM patients with previous exposure to proteasome
inhibitor and lenalidomide-resistant disease
- To evaluate the immunomodulatory effects of nivolumab combined with
daratumumab with or without low dose cyclophosphamide in blood and bone marrow
by using flow cytometric analysis
Part B:
Secondary objectives
- To evaluate toxicity.
- To evaluate progression-free survival
- To evaluate overall survival
- To evaluate prognostic factors for response and survival, which includes
cytogenetic abnormalities by FISH, *2-microgloublin, LDH, and MRD-negativity,
as well as analysis of CD38, CIPs (CD46, CD55, and CD59), PD-L1 and PD1
expression
- To evaluate the effects of daratumumab plus nivolumab with or without low
dose cyclophosphamide on CD38 expression levels, CIPs (CD46, CD55, and CD59),
and immune cells (e.g. T cells, NK cells, Tregs, and MDSCs) by using flow
cytometric analysis and CYTOF
- To analyze the prognostic value of myeloma gene expression profiles
- To assess the prognostic value of mutations as determined by sequencing
Background summary
Myeloma patients who develop bortezomib and lenalidomide-resistant disease have
a very poor survival of only a median of 9 months, indicating that new agents
are urgently needed. Recent studies have shown that daratumumab as a single
agent is effective and well tolerated in these heavily pretreated MM patients.
However, approximately 60% of patients do not achieve a partial response, and
ultimately all patients will develop progressive disease during daratumumab
therapy. In less pretreated patients daratumumab-based combinations
(daratumumab plus lenalidomide-dexamethasone or daratumumab plus
bortezomib-dexamethasone) were very effective and well tolerated. Therefore, in
this study, we will combine daratumumab with other agents to improve survival
of heavily pretreated MM patients.
The PD1 blocker nivolumab, as single agent, does not induce objective responses
but induces stable disease in approximately 67% of relapsed/refractory MM
patients. We have recently shown that daratumumab treatment results in
increased T cell frequencies by eliminating CD38-positive immune suppressor
cells, which probably contributes to the durable responses observed with
daratumumab.
Importantly, low dose cyclophosphamide markedly improves the activity of
monoclonal antibodies such as CD38-targeting antibodies and PD-1 blocking
antibodies.
In this study, we will combine two or three immune modulating agents with
different mechanisms of action in order to improve the outcome of
relapsed/refractory MM patients.
We will evaluate in Part A, nivolumab combined with daratumumab with or without
low dose cyclophosphamide (total 40 patients). Based on efficacy and
tolerability, we will treat in Part B 20 additional patients with nivolumab
combined with daratumumab either with or without low dose cyclophosphamide
based on tolerability and efficacy data obtained in Part A.
Study objective
Evaluation of the effect of nivolumab and daratumumab with or without low dose
cyclophosphamide in patients with relapsed/refractory multiple myeloma
Study design
Prospective, multicenter, phase 2 study
Intervention
daratumumab plus nivolumab of daratumumab plus nivolumab plus low dose
cyclophosphamide
Study burden and risks
The burden will be that daratuumab and nivolumab will be administered as
intravenous infusion. Patients may suffer form side effects, although they are
generally mild for daratumumab. The side effects for nivolumab are also well
described. A small part of the patients (<5%) can experience a immuno mediated
reaction, eg. colitis or hypophysitis or hypothyroidism.
Also for cyclophosphamide the side effects are well known.

Inclusion criteria
1. Age ><=18 years
2. Subject must have documented multiple myeloma as defined by the criteria below:
- Monoclonal plasma cells in the bone marrow *10% at some point in their disease history or presence of a biopsy proven plasmacytoma.
- Measurable disease as defined by any of the following:
- Serum monoclonal paraprotein (M-protein) level *5 g/L (0.5 g/dL); or urine M-protein level *200 mg/24 hours; or serum immunoglobulin free light chain *100 mg/L (10 mg/dL) and abnormal serum immunoglobulin kappa lambda free light chain ratio (See Appendix A)
3. Relapsed or refractory disease. Relapse is defined as progression of disease after an initial response to previous treatment, more than 60 days after cessation of treatment. Refractory disease is defined as <25% reduction in M-protein or progression of disease during treatment or within 60 days after cessation of treatment.
4. Subject had at least 2 prior anti-myeloma regimens.
(Note: Induction, bone marrow transplant with or without maintenance therapy is
considered one regimen.)
5. Subject has developed lenalidomide-refractory disease during prior treatment with a lenalidomide-containing regimen.
Refractory disease is defined as <25% reduction in M-protein or progression of disease
during treatment or within 60 days after cessation of treatment.
6. Subject received prior treatment with a proteasome inhibitor-containing regimen for at
least 2 consecutive cycles.
