Anakinra: Safety and Efficacy in the Management of Fever During Neutropenia and Mucositis in ASCT

Oral and intestinal mucositis are major risk factors for the occurrence of fever during neutropenia and bloodstream infections after intensive chemo- and radiotherapy. These complications often require dose reductions or cause delay of treatment, and thereby interfere with optimal anticancer treatment. Currently, there are no effective strategies to prevent or treat mucositis and the related complications.

The pro-inflammatory cytokine interleukin-1β (IL-1β) has shown pivotal in the pathogenesis of mucositis and recently, it has been established in murine models that IL-1 inhibition significantly ameliorates chemotherapy-induced intestinal mucositis.

In this phase IIa study the safety, maximum tolerated dose and efficacy of anakinra, a recombinant human IL-1 receptor antagonist, will be determined in adult patients with multiple myeloma who receive high-dose melphalan (HDM) in the preparation for an autologous hematopoietic stem cell transplantation (ASCT) and are at high risk for experiencing mucositis and fever during neutropenia (FN). After establishing the optimal dose, a pivotal double-blind randomized placebo-controlled multicenter phase IIb trial will be planned to establish efficacy.


Eligibility Criteria:
Inclusion Criteria:

* Aged ≥ 18 years
* Diagnosed with multiple myeloma
* Scheduled to receive an autologous SCT after myeloablative therapy with high-dose melphalan
* Managed with a central venous catheter (triple- or quadruple lumen)
* Is able and willing to participate
* Has provided written informed consent
* Has a negative tuberculosis Quantiferon test
* Has negative serology for active hepatitis B and C
* Has negative serology for HIV
* Has no known hypersensitivity to Escherichia coli derived products or any components of anakinra
* Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation (during treatment with study medication), and for 30 days after the last dose.

Exclusion Criteria:

* Inability to understand the nature and extent of the trial and the procedures required
* Enrolment in any other investigational treatment study or use of an investigational agent during the stem cell transplantation (this means studies in multiple myeloma regarding induction or maintenance treatment are permitted).
* Women who are pregnant or nursing
* Diagnosed with amyloidosis or light-chain deposition disease
* ALT or AST greater than 2.0 x upper limit of normal (ULN) of the local laboratories values.
* Bilirubin levels greater than 2.0 x upper limit of normal (ULN) of the local Laboratories values, except for benign non-malignant indirect hyperbilirubinemia such as Gilbert syndrome
* Impaired renal function with eGFR \<40 ml/min
* Received a live vaccine during the 3 months prior to baseline visit
* Recent use of IL-1 antagonist, such as anakinra, rilonacept or canakinumab, within three months prior to baseline visit
* Treatment with TNFα inhibiting agents (such as etanercept, adalimumab, infliximab, certolizumab and golimumab).
* Uncontrolled bacterial or viral infections, or fungal infections, at the start of therapy
* Documented colonization with highly resistant microorganisms (HRMOs, in Dutch: BRMO's), prior to registration, or detected during screening procedures
* Documented colonization with methicillin-resistant Staphylococcus aureus (MRSA), prior to registration
* Subjects who are not able to receive antibacterial prophylaxis with quinolones (because of hypersensitivity)
* Subjects with an active solid malignancy prior to registration, with the exception of cutaneous basal or squamous cell carcinomas
* History of mycobacterial infection.
* Subjects with intrinsic disorders of the gastro-intestinal (GI) tract, including, but not limited to: Crohn's disease, ulcerative colitis, celiac disease, short bowel syndrome.
* Subject has any concurrent medical or psychiatric condition or disease that is likely to interfere with the study procedures or results, or that in the opinion of the investigator, would constitute a hazard for participating in this study.
