Inhibition of protein degradation is one of strategies for suppression of uncontrolled proliferation of cancer cells. Proteolytic degradation in cells is mainly ensured by proteasome and its inhibition by bortezomib showed benefit in clinical use for the treatment of multiple myeloma. We report here the library of antiproteasomal O-benzyl salicylamides built from leucine and phenylalanine. Prepared compounds displayed antiproliferative activity on K562, CEM and U266 cancer cell lines, ranging from high micromolar to submicromolar GI50 values...

BACKGROUND: Autologous hematopoietic stem cell transplantation (aHSCT) is the recommended standard upfront treatment for transplant eligible myeloma patients. Considering possible complications related to chemotherapy-cytokine mobilization, cytokine-alone mobilization is often used. We compared mobilization with filgrastim alone to pegfilgrastim alone in newly diagnosed myeloma patients after induction treatment with bortezomib and dexamethasone. The comparison was made between peripheral blood stem cell (PBSC) yields, number of apheresis, hematopoietic stem cell subsets, and time to neutrophil and platelet engraftment after aHSCT...

Autologous stem cell transplantation (ASCT) is a standard treatment for eligible multiple myeloma (MM) patients, but many patients will relapse after ASCT and require subsequent therapy. The proteasome inhibitor carfilzomib is approved for relapsed or refractory MM (RRMM). In phase 3 trials, carfilzomib-based regimens (ASPIRE, carfilzomib-lenalidomide-dexamethasone; ENDEAVOR, carfilzomib-dexamethasone) demonstrated superior progression-free survival (PFS) compared with standard therapies for RRMM (ASPIRE: lenalidomide-dexamethasone; ENDEAVOR, bortezomib-dexamethasone)...

Multiple Myeloma (MM) is characterized by the clonal expansion and metastatic spread of malignant plasma cells to multiple sites in the bone marrow (BM). Recently, we implicated the sialyltransferase ST3Gal-6, an enzyme critical to the generation of E-selectin ligands, in MM BM homing and resistance to therapy. Since E-selectin is constitutively expressed in the BM microvasculature, we wished to establish the contribution of E-selectin ligands to MM biology. We report that functional E-selectin ligands are restricted to a minor subpopulation of MM cell lines which, upon expansion, demonstrate specific and robust interaction with recombinant E-selectin in vitro...

Proteasome inhibitors and immunomodulatory drugs have contributed to the dramatic improvement in survival for patients with myeloma over the past decades. However, the disease typically relapses and new classes of drugs are needed. In 2015, two monoclonal antibodies were approved for the treatment of patients with relapsed multiple myeloma, and immunotherapy has rapidly become indispensable in the management of myeloma patients. Areas covered: Here, the authors discuss the published data regarding the mechanism of action, safety and clinical efficacy of the CD38-targeted monoclonal antibody daratumumab for the treatment of patients with multiple myeloma...

The usefulness of pharmacokinetics of bortezomib for multiple myeloma (MM) with respect to the maximum response to bortezomib and bortezomib-induced peripheral neuropathy (BIPN) development was studied. Maximum response to subcutaneous bortezomib therapy and BIPN occurrence for the first 12 weeks of treatment in 35 MM patients treated by bortezomib-dexamethasone (VD) and bortezomib-melphalan-prednisone (VMP) were evaluated. On day 1 of cycle 1, seven whole-blood samples were collected for 3 h after dosing completion to obtain the maximum plasma concentration and area under the time-concentration curve during 3 h postdose (AUC0-3) in each patient...

Carfilzomib, a proteasome inhibitor, is approved as monotherapy and in combination with dexamethasone or lenalidomide-dexamethasone (Rd) for relapsed or refractory multiple myeloma. The approval of carfilzomib-lenalidomide-dexamethasone (KRd) was based on results from the randomized, phase 3 study ASPIRE (NCT01080391), which showed KRd significantly improved progression-free survival (PFS) vs Rd (median 26.3 vs 17.6 months; hazard ratio (HR)=0.690; P=0.0001). This subgroup analysis of ASPIRE evaluated KRd vs Rd by number of previous lines of therapy and previous exposure to bortezomib, thalidomide or lenalidomide...

Hepatitis B reactivation can occur with various forms of immunosuppression. Cyclophosphamide, Bortezomib, and Dexamethasone (CYBOR-D) chemotherapy is commonly used for the treatment of multiple myeloma and has not been noted in guidelines to be causative in HBV reactivation. Indeed, current guidelines do not recommend providing antiviral prophylaxis to patients with prior HBV infection. We present a case of HBV reactivation as a result of CYBOR-D and autologous stem cell transplant which is complicated by the patient's partner who developed acute hepatitis B...

RATIONALE: Crystalglobulinemia is a rare disease caused by monoclonal immunoglobulins, characterized by irreversible crystallization on refrigeration. It causes systemic symptoms including purpura, arthralgia, and vessel occlusive conditions to be exacerbated by exposure to cold. We report a patient with crystalglobulinemia associated with monoclonal gammopathy of undetermined significance (MGUS) manifesting as chronic arthralgia and recurrent acute arterial occlusion. PRESENTING CONCERNS: A 61-year-old man, who had been diagnosed with MGUS and who had arthralgia of unknown origin, presented with recurrent acute limb ischemia after surgical thromboembolectomy...

Exposure-response analyses of venetoclax in combination with bortezomib and dexamethasone in previously treated patients with multiple myeloma (MM) were performed on a Phase 1b venetoclax dose-ranging study. Logistic regression models were utilized to determine relationships, identify sub-populations with different responses and optimize the venetoclax dosage that balanced both efficacy and safety. Bortezomib refractory status and number of prior treatments were identified to impact the efficacy response to venetoclax treatment...

ABBV-075 is a potent and selective BET family bromodomain inhibitor that recently entered Phase I clinical trials. Comprehensive preclinical characterization of ABBV-075 demonstrated broad activity across cell lines and tumor models representing a variety of hematological malignancies and solid tumor indications. In most cancer cell lines derived from solid tumors, ABBV-075 triggers prominent G1 cell cycle arrest without extensive apoptosis. In this study, we show that ABBV-075 efficiently triggers apoptosis in acute myeloid leukemia (AML), non-Hodgkin's lymphoma (NHL) and multiple myeloma (MM) cells...

Curative responses in the treatment of multiple myeloma (MM) are limited by the emergence of therapeutic resistance. To address this problem, we set out to identify druggable mechanisms that convey resistance to proteasome inhibitors (PIs; e.g., bortezomib), which are cornerstone agents in the treatment of MM. In isogenic pairs of PI sensitive and resistant cells, we observed stark differences in cellular bioenergetics between the divergent phenotypes. PI resistant cells exhibited increased mitochondrial respiration driven by glutamine as the principle fuel source...

A nationwide, multi-institutional survey was performed in 2011 and 2015 to analyze routine practice for myeloma patients outside clinical trials in Germany. We contacted university hospitals, community hospitals, and office-based hematologists in order to enter clinical data from newly diagnosed and relapsed patients into an online platform. Complete datasets were available for 478 (2011) and 515 (2015) patients. While median age at diagnosis increased from 70 to 72 years, patients had fewer concomitant diseases (2011 61%; 2015 51%) and presented with equal performance status (ECOG 0-1, 2011 66%; 2015 68%)...

The unfolded protein response is responsible for the detection of misfolded proteins and the coordination of their disposal and is necessary to maintain the cellular homoeostasis. Multiple myeloma cells secrete large amounts of immunoglobulins, proteins that need to be correctly folded by the chaperone system. If this process fails, the misfolded proteins have to be eliminated by the two main garbage-disposal systems of the cell: proteasome and aggresome. The blockade of either of these systems will result in accumulation of immunoglobulins and other toxic proteins in the cytoplasm and cell death...

We have developed multifunctional nanoparticles (NP) for co-delivery of bortezomib (BTZ) and doxorubicin (DOX) to synchronize their pharmacokinetic profiles and synergize their activities in solid tumor treatment, a need still unmet in the clinic. Micellar NP was formed by a spatially segregated, linear-dendritic telodendrimer containing three segments: a hydrophilic polyethylene glycol (PEG), a BTZ-conjugating intermediate, and a dendritic DOX-affinitive interior. BTZ-conjugated telodendrimers, together with DOX, self-assembled into monodispersed micelles (NP(BTZ-DOX)) with small particle sizes (20~30 nm) for dual drug delivery...

Regulation of the ubiquitin-proteasome system (UPS) to treat select types of cancer has become a popular area of drug discovery research. The FDA approval of proteasome inhibitors Bortezomib and Carfilzomib in the treatment of multiple myeloma has led to an increased need for chemical reporters capable of detecting and quantifying protein ubiquitination and the activity of members of the UPS including E3 ubiquitin ligases and the proteasome in the tumor cells of the patients. One limitation of peptide-based reporters is their rapid degradation in the cellular environment by cytosolic peptidases...
