Meta-Analysis
IMPORTANCE
Cardiovascular adverse events (CVAE) with carfilzomib in patients with multiple myeloma can be potentially life-threatening and remain incompletely characterized. We performed the first systematic review and meta-analysis of carfilzomib-associated CVAE.
OBJECTIVE
To determine the incidence of carfilzomib-associated CVAE and to compare the rates of carfilzomib CVAE among different doses and companion therapies.
DATA SOURCES
PubMed, EMBASE, Web of Science, and clinicaltrials.gov were queried for the keywords "carfilzomib," "Kyprolis," and "PX-171" through January 1, 2017.
STUDY SELECTION
Phase 1 to 3 prospective clinical trials of carfilzomib in patients with multiple myeloma with evaluable toxic effects data were eligible for meta-analysis.
DATA EXTRACTION AND SYNTHESIS
Data were independently extracted by 2 reviewers following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Pooled incidence rates and relative risks (for randomized trials) and 95% confidence intervals were calculated using a random effects model. Subgroup analyses were performed to assess study-level characteristics associated with CVAE.
MAIN OUTCOMES AND MEASURES
Cardiovascular adverse events were defined as heart failure, hypertension, ischemia, and arrhythmia. All-grade and grades 3 or higher AEs and study characteristics were recorded.
RESULTS
A total of 514 studies were assessed for eligibility. Of those, 24 studies were eligible, including a total of 2594 patients with multiple myeloma. All-grade and grades 3 and higher CVAE were seen in 617 (18.1%) and 274 (8.2%), respectively. Phase 2 or 3 studies and carfilzomib doses of 45 mg/m2 or higher were associated with high-grade CVAE. Median age older than 65 years, prior myeloma therapies, and concurrent myeloma therapies were not associated with CVAE. For the 3 randomized clinical trials, the summary relative risk of all-grade and grade 3 or higher CVAE for patients receiving carfilzomib compared with noncarfilzomib-receiving control patients were 1.8 and 2.2, respectively.
CONCLUSIONS AND RELEVANCE
Carfilzomib was associated with a significant incidence of CVAE, with higher rates seen with higher doses of carfilzomib. Phase 1 studies may be underdetecting CVAE. Future studies are needed to identify patients at high risk for CVAE, develop optimal monitoring strategies, and explore strategies to mitigate these risks.

Meta-Analysis Review
BACKGROUND
Immunomodulatory drugs (IMiDs) and proteasome inhibitors have dramatically changed management of multiple myeloma (MM). While MM remains incurable, consolidation and maintenance therapy aimed at improving duration of response can potentially improve survival outcomes. A majority of randomized controlled trials (RCTs) have demonstrated benefit of IMiD-based maintenance therapy in delaying disease progression; however, whether this therapy can lead to improved survival remains controversial.
METHODS
PubMed and abstract databases of major hematology and/or oncology meetings were searched for RCTs that studied maintenance therapy with IMiDs in MM. A meta-analysis was conducted to systematically evaluate the impact of IMiD-based maintenance therapy on survival outcomes and serious adverse events associated with the therapy. All statistical tests were two-sided.
RESULTS
Eighteen phase 3 RCTs enrolling 7730 patients were included. IMiD-based maintenance therapy statistically significantly prolonged progression-free survival (PFS; hazard ratio (HR) = 0.62, 95% confidence interval (CI) = 0.57 to 0.67, P < .001) but failed to improve overall survival (OS; HR = 0.93, 95% CI = 0.85 to 1.01, P = .082). Stratified analyses demonstrated that both thalidomide and lenalidomide provided PFS but not OS benefit in transplantation as well as nontransplantation settings. IMiD-based maintenance therapy in MM led to a higher risk of grade 3-4 thromboembolism (risk ratio = 2.52, 95% CI = 1.41 to 4.52, P = .002). Thalidomide maintenance therapy increased the risk of peripheral neuropathy; lenalidomide maintenance therapy increased the risks of myelosuppression and second primary hematological malignancies.
CONCLUSIONS
Thalidomide- or lenalidomide-based maintenance therapy improves PFS but not OS in MM and increases risks of grade 3-4 adverse events, including thromboembolism, peripheral neuropathy, neutropenia, and infection.

Meta-Analysis
Carfilzomib is a second-generation proteasome inhibitor (PI) that is approved for patients with relapsed or refractory multiple myeloma (RRMM) who failed ≥1 prior lines of therapy. We performed a systematic review of carfilzomib literature with meta-analysis to determine cumulative incidence of cardiotoxicity. After the literature search, we included a total of 29 eligible phase I/II, phase II and phase III clinical trials which used carfilzomib. The cumulative incidence and overall odds ratios (OR) were calculated with random effect model, using 'R' software with metaphor package. A total of 4164 patients with various malignancies were included. The overall estimated cumulative incidence of cardiotoxicity was 8.68% and 4.92%, respectively, for all-grade and high-grade (≥ grade 3) toxicity, which seems higher than other PIs. Compared to control group, the odds of developing cardiotoxicity due to carfilzomib was significantly higher with OR of 2.03 (95% CI: 1.19-3.46, p = .010) and 2.04 (95% CI: 1.31-3.17, p = .002) for all-grades and high grades, respectively. Concomitant immunomodulatory agents seem to increase the risk of cardiotoxicity (high-grade cardiotoxicity 6.45% and 4.34% with and without concomitant immunomodulatory agents, respectively (p = .033)). There was no variation in the incidence of cardiotoxicity among newly diagnosed versus RRMM (p = .38), and high versus standard dose carfilzomib (p = .86).

Review
Standard induction therapy for multiple myeloma is three-drug combination based on following classes of drugs: proteasome inhibitors, immunomodulators and steroids. Despite its notable efficacy, bortezomib has side effects like peripheral neuropathy (PNP) with reported incidence of grade ≥3 PNP between 2%-23% Schlafer et al., 2017. Carfilzomib (CFZ) has high selectivity and minimal off-target adverse effects including lower rates of PNP. CFZ is already approved for treatment of relapsed and refractory multiple myeloma (RRMM) as single agent as well as in combination with lenalidomide and/or dexamethasone. Extensive literature search identified a total of 1839 articles. Twenty-six articles (n = 5980) met the inclusion criteria, 15 in newly diagnosed multiple myeloma (NDMM) and 11 in RRMM group. CFZ demonstrates comparable or even better efficacy to bortezomib with much favorable AE profile. Deep, rapid and sustainable response using KRd with safer toxicity profile supports extension of KRd therapy to frontline therapy for all risk categories of MM. High incidence of grade ≥3 HTN underscores the importance of serial BP monitoring. In RRMM, CFZ has documented efficacy with standard 20-27mg/m2 dose. Further large-scale trials are needed to study benefit-to-risk profile of 20-56 and 20-70 mg/m2 dose of CFZ vs standard 20-27 mg/m2 dose in NDMM and RRMM.

INTRODUCTION
To review the pathogenesis and treatment of multiple myeloma (MM). MM is a hematological malignancy with abnormal plasma cell proliferation in bone marrow. Due to the emergence of drug resistance, MM is still an incurable malignancy, which requires further exploration of pathogenesis and effective therapeutic targets.
METHODS
In this paper, the method of literature review is adopted to obtain the information about MM. Based on the literature, comprehensive and systematic review is made.
RESULTS
MM is a complex pathophysiological process with great heterogeneity, mainly reflected in genomic instability and bone marrow microenvironment. At present, the treatment of MM has made great progress, proteasome inhibitors and immunomodulatory drugs are widely used in clinic. Allogeneic stem cell transplantation may be the only promising cure for MM, and its high transplant-related mortality limits its clinical application.
CONCLUSIONS
The future of MM treatment lies in the development of more targeted therapies, novel immunotherapies, and a better understanding of the disease's molecular and genetic basis.

BACKGROUND AND AIMS
Nonsmall cell lung cancer accounts for over 85% of lung cancer incidences worldwide, and often has a poor prognosis. Proteasome inhibitors, such as bortezomib, have previously demonstrated evidence in preclinical and clinical models in the treatment of NSCLC both alone and as part of chemotherapeutic regimens.
METHODS
Five databases were searched from inception to February 2023 to identify published clinical trial data and ongoing clinical trials on the use of proteasome inhibitors in treatment of NSCLC with a comprehensive search strategy.
RESULTS
This review examines the clinical evidence from 21 completed and published phase I and II trials studying the use of bortezomib monotherapy and combination therapy in the treatment of NSCLC. Bortezomib/docetaxel combination resulted in longer median time-to-progression (TTP), median duration of response, median duration of disease control and median progression-free survival (PFS) than bortezomib monotherapy, with concurrent administration having greater 6-month PFS and median overall survival (OS) than sequential administration. Bortezomib/vorinostat with chemotherapy was well tolerated and effective. Bortezomib/gemcitabine/carboplatin, bortezomib/bevacizumab/carboplatin and bortezomib/paclitaxel/carboplatin combinations showed promising results and were of further investigational value.
CONCLUSION
Bortezomib showed some clinical promise in combination therapy but not monotherapy. It also demonstrated a manageable side effect profile. Combination regimens are of further investigation value in Phase II trials.

Review
Carfilzomib (CFZ) is a proteasome inhibitor currently approved for the treatment of relapsed and refractory multiple myeloma (RRMM). Multiple trials are ongoing to evaluate its efficacy and safety in newly diagnosed multiple myeloma (NDMM). The use of CFZ-based two- or three-drug combination regimens as induction for the management of NDMM is an emerging approach. CFZ-based regimens include combinations of immunomodulators, alkylating agents, and monoclonal antibodies along with dexamethasone. In this review, we assess the efficacy and toxicity of CFZ-based regimens in NDMM. We reviewed a total of 27 studies (n=4538 patients) with overall response rates (ORR) ranging between 80% and 100%. Studies evaluating the combination of CFZ with daratumumab reported an ORR of approximately 100%. Achievement of minimal residual disease (MRD) negativity, measured by multi-parameter flow cytometry (MPFC), ranged between 60% and 95% in 4 (n=251) out of 6 studies that measured MRD-negativity. The interim results of the ENDURANCE trial failed to show superior efficacy and progression-free survival (PFS) of carfilzomib-lenalidomide when compared to bortezomib-lenalidomide combination, albeit with a lower incidence of neuropathy. Hematological toxicity was the most common adverse event observed with these regimens, and the most common non-hematological adverse events were related to cardiovascular and electrolyte disturbances. We need to further evaluate the role of CFZ in NDMM by conducting more Phase III trials with different combinations.

Multiple myeloma is a malignant cancerous condition that is characterized by abnormal plasma cell production and can lead to bone destruction due to increased osteoclastic activity and decreased osteoblastic activity. Many therapeutic therapies are used to treat diseases, such as chemotherapy and radiotherapy. In recent years, anti-sclerostin antibody treatment has been under investigation for its effect on the multiple myeloma. The present study was conducted to assess the effective therapeutic use of anti-sclerostin antibody in the treatment of multiple myeloma. The literature search was conducted using PubMed, Google Scholar, ScienceDirect, and PubMed Central using the following MeSH terms: "multiple myeloma", "anti-sclerostin antibody", "ubiquitin-proteasome pathway", "proteasome inhibitor", "Wnt pathway". A total of 348 articles were screened. Twenty-five out of 348 were full-text articles assessed for eligibility, and four articles were used in this systematic review. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used for the reporting of this systematic review. A total of four randomized control trials (RCT) were included and used in this systematic review. The anti-sclerostin antibodies were various other drugs, and it was found that the anti-sclerostin antibody was effective in preventing autoantibody formation, decreasing bone destruction, and increasing trabecular bone. Anti-sclerostin antibody was found to be effective in decreasing bone destruction by reducing osteoclastic activity and increasing osteoblastic activity associated with multiple myeloma.

Review
Effective new treatments are now available for patients with hematologic malignancies. However, their propensity to cause tumor lysis syndrome (TLS) has not been systematically examined. A literature search identified published Phase I-III clinical trials of monoclonal antibodies (otlertuzumab, brentuximab, obinutuzumab, ibritumomab, ofatumumab); tyrosine kinase inhibitors (alvocidib [flavopiridol], dinaciclib, ibrutinib, nilotinib, dasatinib, idelalisib, venetoclax [ABT-199]); proteasome inhibitors (oprozomib, carfilzomib); chimeric antigen receptor (CAR) T cells; and the proapoptotic agent lenalidomide. Abstracts from major congresses were also reviewed. Idelalisib and ofatumumab had no reported TLS. TLS incidence was ≤5 % with brentuximab vedotin (for anaplastic large-cell lymphoma), carfilzomib and lenalidomide (for multiple myeloma), dasatinib (for acute lymphoblastic leukemia), and oprozomib (for various hematologic malignancies). TLS incidences were 8.3 and 8.9 % in two trials of venetoclax (for chronic lymphocytic leukemia [CLL]) and 10 % in trials of CAR T cells (for B-cell malignancies) and obinutuzumab (for non-Hodgkin lymphoma). TLS rates of 15 % with dinaciclib and 42 and 53 % with alvocidib (with sequential cytarabine and mitoxantrone) were seen in trials of acute leukemias. TLS mitigation was employed routinely in clinical trials of alvocidib and lenalidomide. However, TLS mitigation strategies were not mentioned or stated only in general terms for many studies of other agents. The risk of TLS persists in the current era of novel and targeted therapy for hematologic malignancies and was seen to some extent with most agents. Our findings underscore the importance of continued awareness, risk assessment, and prevention to reduce this serious potential complication of effective anticancer therapy.

Meta-Analysis
BACKGROUND
Current treatments for antibody-mediated rejection (AMR) in kidney transplantation are based on low-quality data from a small number of controlled trials. Novel agents targeting B cells, plasma cells, and the complement system have featured in recent studies of AMR.
METHODS
We conducted a systematic review and meta-analysis of controlled trials in kidney transplant recipients using Medline, EMBASE, and CENTRAL from inception to February 2017.
RESULTS
Of 14 380 citations, we identified 21 studies, including 10 randomized controlled trials, involving 751 participants. Since the last systematic review conducted in 2011, we found nine additional studies evaluating plasmapheresis + intravenous immunoglobulin (IVIG) (two), rituximab (two), bortezomib (two), C1 inhibitor (two), and eculizumab (one). Risk of bias was serious or unclear overall and evidence quality was low for the majority of treatment strategies. Sufficient RCTs for pooled analysis were available only for antibody removal, and here there was no significant difference between groups for graft survival (HR 0.76; 95% CI 0.35-1.63; P = 0.475). Studies showed important heterogeneity in treatments, definition of AMR, quality, and follow-up. Plasmapheresis and IVIG were used as standard-of-care in recent studies, and to this combination, rituximab seemed to add little or no benefit. Insufficient data are available to assess the efficacy of bortezomib and complement inhibitors.
CONCLUSION
Newer studies evaluating rituximab showed little or no difference to early graft survival, and the efficacy of bortezomib and complement inhibitors for the treatment of AMR remains unclear. Despite the evidence uncertainty, plasmapheresis and IVIG have become standard-of-care for the treatment of acute AMR.
