Abstract:

Objective To analyze the status and characteristics of adverse drug reactions(ADRs)induced by ixazommib,and to provide references for the clinical medication. Methods ADRs of ixazommib reported by medical science journals were collected and analyzed statistically from CNKI,VIP,Pubmed,Medline,and Web of Science database from Nov.2015 to Jan.2020. Results A total of 10 ADRs were identified and included in the analysis.Patients at the age between 61 and 80 years showed the highest incidences (n=7).ADRs of ixazommib frequently occurred within 6 weeks after the medication (n=8).Main clinical manifestations were disorders of skin,appendages (n=5),and disorders of hematologic (n=2).Moreover,there were new serious adverse reactions,for example,thrombotic microangiopathies (TMA),progressive multifocal leukoencephalopathy (PML),acute pancreaoitis (AP),and cardiotoxicity. Conclusion Physicians and pharmacists should pay more attention to the safety monitoring of ixazommib during the medication,especially for the new serious adverse reactions,and carefully assess the risk of treatment of re-administration in order for the safe and effective medication.

3 讨论

作为全球首个全口服治疗方案,伊沙佐米与来那度胺和地塞米松的联合治疗方案(IRd)在TOURMALINE-MM1全球Ⅲ期临床试验及中国延展试验中表现出良好的有效性和安全性[11]。然而随着伊沙佐米的上市使用,有关ADRs的个案也陆续报道。本研究收集公开发表的10例个案,均为国外报告。其中严重ADRs共7例,包括SS、TMA、PML、AP,心脏毒性;首次报告新的ADRs 共5例,包括TMA、PML、AP和心脏毒性。ADRs患者中,男性6例,女性4例,性别差异不明显。年龄分布以61~80岁较多(7例),其原因可能与伊沙佐米治疗的原患疾病多见于老年人有关。

表1可知,伊沙佐米致ADRs主要发生在用药前6周(8例),涉及其皮肤及附件损害最多(5例),其中2例为SS,3例为皮肤坏死性血管炎。因此,建议加强患者服药后6周内临床观察,尤其是皮肤及其附件相关ADRs。

本研究收集的5例皮肤及其附件损害个案中,包括SS和皮肤坏死性血管炎。SS又称急性发热性嗜中性皮病,以发热、疼痛性红色丘疹、斑块或结节,伴有中性粒细胞升高,中性粒细胞浸润真皮为特征的一组疾病[12]。目前将SS分为3类:特发型、副肿瘤型和药物诱发型。其中,药物诱发型SS通常发生在化疗第一和第二周期,与本研究调查基本一致。伊沙佐米致SS的机制尚不完全清楚,可能与细胞因子[核因子-κB、白细胞介素(IL)-6、粒细胞集落刺激因子]失衡导致中性粒细胞向真皮的趋化性迁移有关[13]。本研究的个案显示,发生SS应立即停用伊沙佐米,适当给予糖皮质激素治疗,避免SS迁延造成多系统、器官反复受累,皮损通常会在2周内消退。本研究收集到3例皮肤坏死性血管炎报告。目前伊沙佐米诱发皮肤性血管炎的机制尚不完全清楚,但IL-6、肿瘤坏死因子-α(TNF-α)等细胞因子在其中可能发挥一定作用。个案中尽管出现严重的皮损,但由于未累及其他系统,均通过减少伊沙佐米剂量,在非治疗日联用小剂量糖皮质激素,取得了良好的临床效果。

伊沙佐米致TMA 2例。TMA是以血小板减少、溶血性贫血和缺血性终末器官损害为特征的疾病。药物引起的TMA又称为药物诱导型TMA(drug-induced TMA,DTMA)[14]。关于DTMA的发生机制,目前有免疫介导和剂量依赖两种假说:前者为特异质反应,与内皮细胞损伤、药物反应性抗体形成有关;后者认为微血管损伤,尤其是肾小球毛细血管损伤在其中发挥重要作用[15]。目前广泛认为,免疫介导机制通常发生在给药后24小时内或给药后21 d内[6],不符合以上时间标准的则为剂量依赖机制。个案6中DTMA出现在给药后第17天,给予利妥昔单抗和血浆置换治疗有效,考虑免疫介导引起;个案7中DTMA出现时间为第56天,患者给予血浆置换病情无改善,考虑药物累积毒性所致。一旦发生DTMA,应立即停用伊沙佐米[16]。对于能否再次使用伊沙佐米,取决于DTMA的发生机制:若考虑免疫介导引起,则不应再给药;若考虑为剂量依赖机制,评估重新给药的潜在获益和DTMA再发风险后,可谨慎的引入合适剂量的药物。

伊沙佐米致PML 1例。PML是由JC病毒引起的一种罕见而严重的中枢神经系统脱髓鞘病变,临床表现为运动无力、视觉功能缺陷、步态异常和语言问题等[17]。研究显示,长期及多种免疫抑制剂或免疫调节剂的使用,增加药源性PML的风险[18],与本研究调查一致。PML患者预后极差,尤其是高龄、脑脊液JC病毒浓度较高、影像学广泛病灶均是预后不良的危险因素[18]。研究显示,对于那他珠单抗所致的PML,给予米氮平或甲氟喹可产生积极的临床效果,但个案8中患者每日服用米氮平15 mg,神经症状仍进行性下降,因此,对于伊沙佐米此类血浆蛋白结合率高的药物,可积极辅以血浆置换,以加速药物的清除[19]。因此,鉴于PML目前尚无特效药物及毁灭性的后果,临床医生在治疗过程中,对有神经症状的MM患者应保持高度警惕,一旦诊断PML,需立即停用免疫抑制剂,迅速重建机体免疫系统,并控制PML相关免疫重建炎性综合征的发生[19],改善患者预后。

药物性胰腺炎(drug-induced pancreaoitis,DIP)占胰腺炎病例的0.1%~2%,通常是一种排他性诊断。学者认为,伊沙佐米诱发的DIP可能与PI靶向效应或药物的过敏/免疫反应引起胰腺充血、水肿释放炎性介质进而激活胰酶有关[20,21],其潜伏期短,多为2~3周,发作与药物剂量无关[22],与本研究调查基本一致。尽管伊沙佐米的腹泻、便秘、恶心等胃肠道不良反应比较常见(主要为1级和2级),但临床医生应高度重视以腹痛为首发症状的患者,筛查DIP的可能性,及时停用伊沙佐米,辅助相应的支持治疗措施,防止胰腺的持续损伤,降低DIP并发症和死亡率。

伊沙佐米致心脏毒性1例。目前认为伊沙佐米所致的心脏毒性与泛素-蛋白酶体系统(ubiquitin proteasome system,UPS)抑制作用有关[23]。动物实验表明,长期大剂量的PI暴露是心脏毒性增加的独立危险因素,尤其是在存在高血脂症的情况下[24]。个案10 中患者有阵发性房颤病史,随着伊沙佐米累计剂量的增加,患者出现逐渐加重的劳力性呼吸困难、急性失代偿性心力衰竭,与文献报道一致[24]。对于伊沙佐米致心脏毒性,目前缺乏相对特效药物,因此,早期预防显得尤为重要。鉴于MM患者的中位诊断年龄为70岁,在使用伊沙佐米前,医生应全面评估患者的心脏功能,学者提出“整体纵向应变(global longitudinal strain,GLS)”作为接受化疗患者心脏毒性早期预测因子具有积极的价值 [25],同时用药期间建议加强靶向肿瘤治疗预防心脏毒性的“ABCDE”(A:意识、评估、阿司匹林,B:血压控制,C:降低胆固醇、戒烟,D:饮食、化疗剂量、糖尿病管理,E:运动、超声心动图)方法的宣教[26],一旦出现呼吸困难、胸痛、水肿等心肺症状,应及时监测患者心功能指标,积极对症支持治疗。

综上所述,作为首个全口服治疗方案,伊沙佐米被寄予厚望。随着伊沙佐米应用的日益广泛,许多不良反应也日渐显现,尤其是新的严重不良反应,如TMA、PML、AP和心脏毒性等,预后普遍较差,应引起临床医师和药师的高度重视。医疗机构应加强对伊沙佐米致ADRs的认识和监测,谨慎评估再次给药的风险和收益,保证临床用药安全、有效。

INTRODUCTION: Despite a major positive impact of proteasome inhibitors (PI), such as bortezomib and carfilzomib, on the survival of patients with multiple myeloma (MM) over the last few years, their use in clinical practice is limited by the development of drug resistance, significant side-effects or constraining administration schedules. Ixazomib is the first, and for now the only, oral PI, which was approved by the US Food and Drug Administration in 2015 and by the European Medicines Agency in 2016. Areas covered: In this review, we provide an overview of the preclinical and early-phase studies of ixazomib used as single-agent and in combination. Furthermore, we discuss the results of a recently published pivotal trial, which evaluated the safety profile and clinical benefit of the combination of ixazomib, lenalidomide and dexamethasone versus lenalidomide and dexamethasone alone in 722 patients with relapsed/refractory MM. Expert opinion: Ixazomib combines the comfort of oral administration, substantial clinical efficacy and a good safety profile with manageable side-effects, which mainly comprise low-grade hematological, digestive or cutaneous events, and the agent will therefore play an active part in long-term treatment strategies, both as single agent and as part of combination regimens. Ongoing phase III trials are currently defining its place in first-line, maintenance and relapse settings.

Ixazomib is the only oral proteasome inhibitor used in relapsed/refractory myeloma. Cutaneous side effects due to ixazomib have been documented in the literature; however, cutaneous necrotizing vasculitis is extremely rare. We describe a case of a 74-year-old man with relapsed multiple myeloma who was started on ixazomib, lenalidomide, and dexamethasone. He developed several skin lesions that were biopsied and revealed cutaneous necrotizing vasculitis. Ixazomib was held with resolution of the vasculitic lesions and restarted with dexamethasone to 20 mg on the day of treatment and 20 mg dose the day after treatment.

Ixazomib is a second-generation proteasome inhibitor that has been approved in the combination treatment of multiple myeloma and is currently under clinical investigation for the management of Waldenstrom's macroglobulinemia. While cutaneous adverse events secondary to proteasome inhibitors have been reported, the side effect profile of ixazomib remains to be documented. We report two patients, one with multiple myeloma and one with Waldenstrom's macroglobulinemia, who developed cutaneous necrotizing vasculitis after the initiation of ixazomib. Both patients exhibited no signs of systemic vasculitis and completed their anti-cancer regimens with resolution of their respective eruptions following dose reductions in ixazomib and initiation of low-dose prednisone. A collaborative effort towards the characterization of such cutaneous toxicities facilitates early intervention, maintenance of life-preserving anti-cancer therapy, and allows clinicians opportunity to better understand the pathophysiology of vasculitis. Moreover, appropriate identification and characterization of cutaneous toxicities from novel therapies allows providers to accurately identify safety concerns, treat toxicity, and improve patient quality of life.

Drug-induced thrombotic microangiopathies (DTMAs) are increasingly being recognized as an important category of thrombotic microangiopathies (TMAs). Cancer therapeutic agents including proteasome inhibitors (PIs) are among the most common medications reported to cause DTMA. PIs could cause DTMA either by an immune mechanism or dose-dependent/cumulative toxicity. Eleven cases of DTMA have been reported with bortezomib and carfilzomib. To the best of our knowledge, only one case of DTMA has been reported with ixazomib due to an immune-mediated mechanism. Here, we report the first case of ixazomib-induced DTMA due to cumulative toxicity rather than immune-mediated mechanism. In this article, we discuss the precipitating factors for cumulative toxicity of ixazomib, resulting in DTMA, diagnostic workup, and management of DTMA. We also discuss clinical reasoning based analysis of DTMA versus cancer-associated TMA as well as DTMA versus cyclic thrombocytopenia seen in PI use.

Progressive multifocal leukoencephalopathy (pml) is a rare demyelinating disease of the central nervous system that most often affects immunocompromised individuals. It is caused by the reactivation of the John Cunningham virus (jcv), which is found in latent form in the majority of adults. We describe a 59-year-old man with multiple myeloma who developed severe neurological deficits during treatment with ixazomib-based chemotherapy. A diagnosis of pml was established with gadolinium-enhanced magnetic resonance imaging (mri) and by detection of jcv in the cerebrospinal fluid. Despite cessation of chemotherapy and treatment with mirtazapine, he had an inexorable neurological decline and died two months after presenting to hospital. Multiple myeloma and its treatments can predispose patients to opportunistic infections including pml. Although there have been case reports of pml in patients with multiple myeloma treated with bortezomib (a different proteosome inhibitor), this is, to our knowledge, the first documented case of pml in a patient treated with a regimen that includes ixazomib.

BACKGROUND: Acute pancreatitis is an uncommon complication of anti-myeloma agents. Ixazomib is a first-in-class oral proteasome inhibitor to receive regulatory approval for the treatment of multiple myeloma. This case report describes the first case of ixazomib-associated pancreatitis. CASE PRESENTATION: An 80-year-old female with relapsed multiple myeloma presented with severe diarrhea, nausea, vomiting, abdominal pain, and acute renal failure 3 weeks after starting ixazomib and dexamethasone for disease progression. An extensive workup revealed acute pancreatitis without a definitive cause. Her condition improved with supportive measures and the discontinutation of ixazomib. The latter was suspected as the probable etiology of the patient's acute pancreatitis, given no clear alternative causes and the temporal relationship between initiating ixazomib and the development of her symptoms. CONCLUSIONS: Practitioners should include acute pancreatitis as part of their differential diagnosis in patients on ixazomib treatment who present with gastrointestinal symptoms.

Ixazomib, the first oral proteasome inhibitor, is approved in combination with lenalidomide and dexamethasone for the treatment of patients with multiple myeloma (MM) who have received at least one prior therapy. Ixazomib is a selective, potent, and reversible inhibitor of the 20S proteasome, and preferentially binds to and inhibits the beta5 chymotrypsin-like proteolytic site. Ixazomib absorption is rapid, with a median time to reach maximum plasma concentration of approximately 1 h post-dose. Ixazomib pharmacokinetics (PK) are adequately described by a three-compartment model (terminal half-life of 9.5 days) with first-order linear absorption (oral bioavailability of 58%). Plasma exposures of ixazomib increase in a dose-proportional manner. A high-fat meal decreases both the rate and extent of ixazomib absorption, supporting administration on an empty stomach. Population PK analyses demonstrated that no dose adjustment is required based on age, body size/weight, race, sex, mild-to-moderate renal impairment, or mild hepatic impairment. Results from dedicated studies indicate that a reduced starting dose (from 4 to 3 mg) is appropriate for patients with severe renal impairment, end-stage renal disease requiring dialysis, or moderate-to-severe hepatic impairment. Non-cytochrome P450 (CYP)-mediated metabolism appears to be the major clearance mechanism for ixazomib. Drug-drug interaction studies have shown no meaningful effects of strong inhibitors of CYP3A on ixazomib PK; however, the strong inducer rifampin caused a clinically relevant reduction in ixazomib exposure, supporting the recommendation to avoid concomitant administration of ixazomib with strong CYP3A inducers. Exposure-response analyses of data from the phase III TOURMALINE-MM1 registrational study demonstrate a favorable benefit-risk profile for the approved dose and regimen of weekly ixazomib 4 mg on days 1, 8, and 15 of each 28-day cycle.

BACKGROUND: Sweet syndrome (SS) is an infrequent skin disease characterised by sudden onset of fever, leukocytosis, neutrophilia, and tender erythematous plaques infiltrated by neutrophils. Multiple conditions have been associated with this syndrome. OBJECTIVES: The aim of this study was to evaluate the clinical, epidemiological, laboratory, and histopathological findings and associations of patients with SS. METHODS: We conducted a retrospective study of 83 patients with SS followed between January 1, 2006, and January 31, 2015. RESULTS: Of the patients, 82% were female; the mean age at onset was 48 years. Clinical presentation was mainly characterised by erythematous and edematous plaques, mostly on upper extremities and trunk. Fever was observed in 32%; 60% presented leukocytosis and 39% neutrophilia. On histopathological examination, neutrophilic and lymphohistiocytic infiltrate and edema were the most frequent findings. Fourteen percent of patients had malignancy or hematologic disorders, 26% were classified as having drug-induced SS, and 24% noted recent infection. Only 2 cases occurred during pregnancy. Systemic corticosteroid was the most common choice of treatment, with excellent response. In malignancy-associated SS, the mean hemoglobin level was lower ( P = .01) and the erythrocyte sedimentation rate (ESR) was higher ( P = .04) in comparison to classic and drug-induced SS. Leukocytoclasia was associated with higher risk of recurrence ( P = .01). CONCLUSION: All patients with SS deserve careful investigation of possible underlying conditions. Higher ESR and lower hemoglobin levels might reinforce the need of malignancy screening. Also, leukocytoclasia appears to be a potential marker of higher recurrence rate, demanding closer and longer follow-up.

Many drugs have been reported to cause thrombotic microangiopathy (TMA), often described as thrombotic thrombocytopenic purpura (TTP) or hemolytic-uremic syndrome (HUS). We recently established criteria to evaluate the evidence for a causal association of a drug with TMA and then we systematically reviewed all published reports of drug-induced TMA (DITMA) to determine the level of evidence supporting a causal association of the suspected drug with TMA. On the basis of this experience, we used these evaluation criteria to assess the Oklahoma TTP-HUS Registry patients who had been previously categorized as drug-induced, 1989-2014. We also reviewed the experience of the BloodCenter of Wisconsin with testing for drug-dependent antibodies reactive with platelets and neutrophils in patients with suspected immune-mediated DITMA, 1988-2014. Among 58 patients in the Oklahoma Registry previously categorized as drug-induced (15 suspected drugs), 21 patients (three drugs: gemcitabine, pentostatin, quinine) had evidence supporting a definite association with TMA; 19 (90%) of the 21 patients had quinine-induced TMA. The BloodCenter of Wisconsin tested 40 patients with suspected DITMA (eight drugs); drug-dependent antibodies, supporting a definite association with TMA, were identified in 30 patients (three drugs: oxaliplatin, quinine, vancomycin); 28 (93%) of the 30 patients had quinine-induced TMA. Combining the data from these two sources, 51 patients (five drugs) have been identified with evidence supporting a definite association with TMA. DITMA was attributed to quinine in 47 (92%) of these 51 patients.

Bortezomib, a proteasome inhibitor with efficacy in multiple myeloma, is associated with thrombocytopenia, the cause and kinetics of which are different from those of standard cytotoxic agents. We assessed the frequency, kinetics, and mechanism of thrombocytopenia following treatment with bortezomib 1.3 mg/m2 in 228 patients with relapsed and/or refractory myeloma in 2 phase 2 trials. The mean platelet count decreased by approximately 60% during treatment but recovered rapidly between treatments in a cyclic fashion. Among responders, the pretreatment platelet count increased significantly during subsequent cycles of therapy. The mean percent reduction in platelets was independent of baseline platelet count, M-protein concentration, and marrow plasmacytosis. Plasma thrombopoietin levels inversely correlated with platelet count. Murine studies demonstrated a reduction in peripheral platelet count following a single bortezomib dose without negative effects on megakaryocytic cellularity, ploidy, or morphology. These data suggest that bortezomib-induced thrombocytopenia is due to a reversible effect on megakaryocytic function rather than a direct cytotoxic effect on megakaryocytes or their progenitors. The exact mechanism underlying bortezomib-induced thrombocytopenia remains unknown but it is unlikely to be related to marrow injury or decreased thrombopoietin production.

Thrombotic thrombocytopenia purpura (TTP) and the hemolytic uremic syndrome (HUS) are rare thrombotic microangiopathies that can be rapidly fatal. Although the acquired versions of TTP and HUS are generally highest on this broad differential, multiple rarer entities can produce a clinical picture similar to TTP/HUS, including microangiopathic hemolysis, renal failure, and neurologic compromise. More recent analysis has discovered a host of genetic factors that can produce microangiopathic hemolytic syndromes. This article discusses the current understanding of thrombotic microangiopathy and outlines the pathophysiology and causative agents associated with each distinct syndrome as well as the most accepted treatments.

OBJECTIVE: Natalizumab, a therapy for multiple sclerosis (MS), has been associated with progressive multifocal leukoencephalopathy (PML), a rare opportunistic infection of the CNS associated with the JC virus. We assessed clinical outcomes and identified variables associated with survival in 35 patients with natalizumab-associated PML. METHODS: Physicians provided Karnofsky scores and narrative descriptions of clinical status. Data were supplemented by the natalizumab global safety database. RESULTS: At the time of analysis, 25 patients (71%) had survived. Survivors were younger (median 40 vs 54 years) and had lower pre-PML Expanded Disability Status Scale scores (median 3.5 vs 5.5) and a shorter time from symptom onset to diagnosis (mean 44 vs 63 days) compared with individuals with fatal cases. Of patients with nonfatal cases, 86% had unilobar or multilobar disease on brain MRI at diagnosis, whereas 70% of those with fatal cases had widespread disease. Gender, MS duration, natalizumab exposure, prior immunosuppressant use, and CSF JC viral load at diagnosis were comparable. Most patients were treated with rapid removal of natalizumab from the circulation. The majority of patients developed immune reconstitution inflammatory syndrome and were treated with corticosteroids. Among survivors with at least 6 months follow-up, disability levels were evenly distributed among mild, moderate, and severe, based on physician-reported Karnofsky scores. CONCLUSIONS: Natalizumab-associated PML has improved survival compared with PML in other populations. Disability in survivors ranged from mild to severe. A shorter time from symptom onset to diagnosis and localized disease on MRI at diagnosis were associated with improved survival. These data suggest that earlier diagnosis through enhanced clinical vigilance and aggressive management may improve outcomes.

Acute pancreatitis is a rare complication of chemotherapy agents. We describe the case of a patient with multiple myeloma who developed acute pancreatitis after treatment with bortezomib, a proteasome inhibitor commonly used in the treatment of this disease. We reviewed the available medical literature on this topic, and found other seven similar cases, all after intravenous bortezomib. Our case is the first one occurring with the subcutaneous route of administration.

PURPOSE: To assess the safety and efficacy of upfront treatment using bortezomib combined with standard radiation therapy (RT) and temozolomide (TMZ), followed by adjuvant bortezomib and TMZ for /=18 months compared with historical norms (25.0% at 18 and 24 months; 16.7% at 30 months). In terms of overall survival (OS), the median OS was 19.1 months (95% CI 6.7-31.4), with improved OS rates at >/=12 months (87.5% at 12, 50.0% at 24, 34.1% at 36-60 months) compared with the historical norms. The median PFS was 24.7 months (95% CI 8.5-41.0) in 10 MGMT methylated and 5.1 months (95% CI 3.9-6.2) in 13 unmethylated patients. The estimated median OS was 61 months (95% CI upper bound not reached) in the methylated and 16.4 months (95% CI 11.8-21.0) in the unmethylated patients. CONCLUSIONS: The addition of bortezomib to current standard radiochemotherapy in newly diagnosed GBM patients was tolerable. The PFS and OS rates appeared promising, with more benefit to MGMT methylated patients. Further clinical investigation is warranted in a larger cohort of patients.

The proteasome prevents the intracellular accumulation of proteins and its impairment can lead to structural and functional alterations, as noted for the coronary vasculature in a previous study. Utilizing the same model, this study was designed to test the hypothesis that chronic proteasome inhibition (PSI) also leads to structural and functional changes of the heart.
Female domestic pigs were randomized to a normal diet without (N) or with twice-weekly subcutaneous injections of the proteasome inhibitor MLN-273 (0.08 mg/kg, N PSI, n 5 each group). In vivo data on cardiac structure and function as well as myocardial perfusion and microvascular permeability response to adenosine and dobutamine were obtained by electron beam computed tomography after 11 weeks. Subsequent ex vivo myocardial analyses included immunoblotting, immunostaining, TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labelling), Masson trichrome, and Congo red staining. Compared with N, an increase in LV mass was observed in N PSI (106.5 16.4 g vs. 183.1 24.2 g, P 0.05). The early to late diastolic filling ratio was increased in N PSI vs. N (3.5 0.6 vs. 1.8 0.1, P 0.05). The EF tended to be lower (46 12 and 53 9, respectively) and cardiac output was significantly lower in N PSI than in N (2.9 1.1 vs. 4.7 1.1 L/min, P 0.05). Tissue analyses demonstrated an accumulation of proteasome substrates, apoptosis, and fibrosis in the PSI group. Compared with N, the myocardial perfusion response was reduced and microvascular permeability was increased in N PSI.
The current study demonstrates that chronic proeasome inhibition affects the cardiovascular system, leading to functional and structural alteration of the heart consistent with a hypertrophicrestrictive cardiomyopathy phenotype.
