INDICATIONS AND USAGE1.1 Prophylaxis of Invasive Aspergillus and Candida InfectionsNOXAFIL Oral Suspension is indicated for prophylaxis of invasive Aspergillus and Candida infections in patients, 13 years of age and older, who are at high risk of developing these infections due to being severely immunocompromised, such as hematopoietic stem cell transplant (HSCT) recipients with graft-versus-host disease (GVHD) or those with hematologic malignancies with prolonged neutropenia from chemotherapy.1.2 Treatment of Oropharyngeal Candidiasis Including Oropharyngeal Candidiasis Refractory to Itraconazole and/or FluconazoleNOXAFIL is indicated for the treatment of oropharyngeal candidiasis, including oropharyngeal candidiasis refractory to itraconazole and/or fluconazole.2. DOSAGE AND ADMINISTRATION2.1DosageIndication Dose and Duration of TherapyProphylaxis of Invasive Fungal Infections 200 mg (5 mL) three times a day. The duration of therapy is based on recovery from neutropenia or immunosuppression.Oropharyngeal Candidiasis Loading dose of 100 mg (2.5 mL) twice a day on the first day, then100 mg (2.5 mL) once a day for 13 days.Oropharyngeal Candidiasis Refractory to itraconazole and/or fluconazole 400 mg (10 mL) twice a day. Duration of therapy should be based on the severity of the patient’s underlying disease and clinical response.2.2Administration InstructionsShake NOXAFIL Oral Suspension well before use.Figure 1: A measured dosing spoon is provided, marked for doses of 2.5 mL and 5 mL.It is recommended that the spoon is rinsed with water after each administration and before storage.Each dose of NOXAFIL should be administered with a full meal or with a liquid nutritional supplement or an acidic carbonated beverage (e.g. ginger ale) in patients who cannot eat a full meal.To enhance the oral absorption of posaconazole and optimize plasma concentrations:•Each dose of NOXAFIL should be administered during or immediately (i.e. within 20 minutes) following a full meal. In patients who cannot eata full meal, each dose of NOXAFIL should be administered with a liquid nutritional supplement or an acidic carbonated beverage. For patientswho cannot eat a full meal or tolerate an oral nutritional supplement or an acidic carbonated beverage, alternative antifungal therapy should be considered or patients should be monitored closely for breakthrough fungal infections.•Patients who have severe diarrhea or vomiting should be monitored closely for breakthrough fungal infections.•Co-administration of drugs that can decrease the plasma concentrations of posaconazole should generally be avoided unless the benefit outweighs the risk. If such drugs are necessary, patients should be monitored closely for breakthrough fungal infections [see Drug Interactions(7.6, 7.7, 7.8, 7.9, 7.13)].3. DOSAGE FORMS AND STRENGTHSNOXAFIL Oral Suspension is available in 4-ounce (123 mL) amber glass bottles with child-resistant closures (NDC 0085-1328-01) containing105 mL of suspension (40 mg of posaconazole per mL).4. CONTRAINDICATIONS4.1HypersensitivityNOXAFIL is contraindicated in persons with known hypersensitivity to posaconazole, any component of NOXAFIL, or other azole antifungal agents.4.2 Use With SirolimusNOXAFIL is contraindicated with sirolimus. Concomitant administration of NOXAFIL with sirolimus increases the sirolimus blood concentrations by approximately 9 fold and can result in sirolimus toxicity [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)].4.3 QT Prolongation With Concomitant Use With CYP3A4 SubstratesNOXAFIL is contraindicated with CYP3A4 substrates that prolong the QT interval. Concomitant administration of NOXAFIL with the CYP3A4 substrates, pimozide and quinidine may result in increased plasma concentrations of these drugs, leading to QTc prolongation and rare occurrences of torsades de pointes [see Warnings and Precautions (5.2) and Drug Interactions (7.2)].4.4 Use With SimvastatinConcomitant administration of NOXAFIL with simvastatin increases the simvastatin plasma concentrations by approximately 10 fold. Increased plasma statin concentrations can be associated with rhabdomyolysis [see Drug Interactions (7.3) and Clinical Pharmacology (12.3)].4.5 Use With Ergot AlkaloidsPosaconazole may increase the plasma concentrations of ergot alkaloids (ergotamine and dihydroergotamine) which may lead to ergotism [see Drug Interactions (7.4)].5. WARNINGS AND PRECAUTIONS5.1 Calcineurin-Inhibitor Drug InteractionsConcomitant administration of NOXAFIL with cyclosporine or tacrolimus increases the whole blood trough concentrations of these calcineurin-inhibitors [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)]. Nephrotoxicity and leukoencephalopathy (including isolated deaths) have been reported in clinical efficacy studies in patients with elevated cyclosporine concentrations. Frequent monitoring of tacrolimus or cyclosporine whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the tacrolimus or cyclosporine dose adjusted accordingly.5.2 Arrhythmias and QT ProlongationSome azoles, including posaconazole, have been associated with prolongation of the QT interval on the electrocardiogram. In addition, rare cases of torsades de pointes have been reported in patients taking posaconazole.Results from a multiple time-matched ECG analysis in healthy volunteers did not show any increase in the mean of the QTc interval. Multiple, time-matched ECGs collected over a 12-hour period were recorded at baseline and steady-state from 173 healthy male and female volunteers (18-85 years of age) administered posaconazole 400 mg BID with a high-fat meal. In this pooled analysis, the mean QTc (Fridericia) interval change from baseline was –5 msec following administration of the recommended clinical dose. A decrease in the QTc (F) interval (–3 msec) was also observed in a small number of subjects (n=16) administered placebo. The placebo-adjusted mean maximum QTc (F) interval change from baseline was <0 msec (–8 msec). No healthy subject administered posaconazole had a QTc (F) interval ≥500 msec or an increase ≥60 msec in their QTc (F) interval from baseline.Posaconazole should be administered with caution to patients with potentially proarrhythmic conditions. Do not administer with drugs that are known to prolong the QTc interval and are metabolized through CYP3A4 [see Contraindications (4.3) and Drug Interactions (7.2)]. Rigorous attempts to correct potassium, magnesium, and calcium should be made before starting posaconazole.5.3 Hepatic ToxicityHepatic reactions (e.g.,mild to moderate elevations in alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, total bilirubin, and/or clinical hepatitis) have been reported in clinical trials. The elevations in liver function tests were generally reversible on discontinuation of therapy, and in some instances these tests normalized without drug interruption and rarely required drug discontinuation. Isolated cases of more severe hepatic reactions including cholestasis or hepatic failure including deaths have been reported in patients with serious underlying medical conditions (e.g., hematologic malignancy) during treatment with posaconazole. These severe hepatic reactions were seen primarily in subjects receiving the 800 mg daily (400 mg BID or 200 mg QID) in clinical trials.Liver function tests should be evaluated at the start of and during the course of posaconazole therapy. Patients who develop abnormal liver function tests during posaconazole therapy should be monitored for the development of more severe hepatic injury. Patient management should include laboratory evaluation of hepatic function (particularly liver function tests and bilirubin). Discontinuation of posaconazole must be considered if clinical signs and symptoms consistent with liver disease develop that may be attributable to posaconazole.5.4 Use With MidazolamConcomitant administration of NOXAFIL with midazolam increases the midazolam plasma concentrations by approximately 5 fold. Increased plasma midazolam concentrations could potentiate and prolong hypnotic and sedative effects. Patients must be monitored closely for adverse effects associated with high plasma concentrations of midazolam and benzodiazepine receptor antagonists must be available to reverse these effects [see Drug Interactions (7.5) and Clinical Pharmacology (12.3)].6. ADVERSE REACTIONS6.1 Serious and Otherwise Important Adverse ReactionsThe following serious and otherwise important adverse reactions are discussed in detail in another section of the labeling: • Hypersensitivity[see Contraindications (4.1)]•Arrhythmias and QT Prolongation [see Warnings and Precautions (5.2)][see Warnings and Precautions (5.3)]• HepaticToxicity6.2 Clinical Trials ExperienceBecause clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of NOXAFIL cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.The safety of posaconazole therapy has been assessed in 1844 patients in clinical trials. This includes 605 patients in the active-controlled prophylaxis studies, 557 patients in the active-controlled OPC studies, 239 patients in refractory OPC studies, and 443 patients from other indications. Thisrepresents a heterogeneous population, including immunocompromised patients, e.g., patients with hematological malignancy, neutropenia post-chemotherapy, graft vs. host disease post hematopoietic stem cell transplant, and HIV infection, as well as non-neutropenic patients. This patient population was 71% male, had a mean age of 42 years (range 8-84 years, 6% of patients were ≥65 years of age and 1% was <18 years of age), and were 64% white, 16% Hispanic, and 36% non-white (including 14% black). Posaconazole therapy was given to 171 patients for ≥6 months, with 58 patients receiving posaconazole therapy for ≥12 months. Table 1 presents treatment-emergent adverse reactions observed at an incidence of >10% in posaconazole prophylaxis studies. Table 2 presents treatment-emergent adverse reactions observed at an incidence of at least 10% in the OPC/rOPC studies.Prophylaxis of Aspergillus and Candida: In the 2 randomized, comparative prophylaxis studies, the safety of posaconazole 200 mg threetimes a day was compared to fluconazole 400 mg once daily or itraconazole 200 mg twice a day in severely immunocompromised patients.The most frequently reported adverse reactions (>30%) in the prophylaxis clinical trials were fever, diarrhea and nausea.The most common adverse reactions leading to discontinuation of posaconazole in the prophylaxis studies were associated with GI disorders,specifically, nausea (2%), vomiting (2%), and hepatic enzymes increased (2%).TABLE 1: Study 1 and Study 2.

In the refractory OPC pool, the most common adverse reactions that led to treatment discontinuation of posaconazole were AIDS (7%) and respiratory insufficiency (3%).TABLE 2: Treatment-Emergent Adverse Reactions With Frequency of at Least 10% in OPC Studies (Treated Population)Number (%) of SubjectsControlled OPC Pool Refractory OPC PoolPosaconazole Fluconazole PosaconazoleBody SystemPreferred Term n=557 n=262 n=239356 (64) 175 (67) 221 (92)Subjects Reporting any AdverseReaction*Body as a Whole – General DisordersFever 34 (6) 22 (8) 82 (34)Headache 44 (8) 23 (9) 47 (20)Anorexia 10 (2) 4 (2) 46 (19)Fatigue 18 (3) 12 (5) 31 (13)Asthenia 9 (2) 5 (2) 31 (13)Rigors 2 (<1) 4 (2) 29 (12)Pain 4 (1) 2 (1) 27 (11)Disorders of Blood and Lymphatic SystemNeutropenia 21 (4) 8 (3) 39 (16)Anemia 11 (2) 5 (2) 34 (14)Gastrointestinal System DisordersDiarrhea 58 (10) 34 (13) 70 (29)Nausea 48 (9) 30 (11) 70 (29)Vomiting 37 (7) 18 (7) 67 (28)Abdominal Pain 27 (5) 17 (6) 43 (18)Infection and InfestationsCandidiasis, Oral 3 (1) 1 (<1) 28 (12)Herpes Simplex 16 (3) 8 (3) 26 (11)Pneumonia 17 (3) 6 (2) 25 (10)Metabolic and Nutritional DisordersWeight Decrease 4 (1) 2 (1) 33 (14)Dehydration 4 (1) 7 (3) 27 (11)Psychiatric DisordersInsomnia 8 (1) 3 (1) 39 (16)Respiratory System DisordersCoughing 18 (3) 11 (4) 60 (25)Dyspnea 8 (1) 8 (3) 28 (12)Skin and Subcutaneous Tissue DisordersRash 15 (3) 10 (4) 36 (15)Sweating Increased 13 (2) 5 (2) 23 (10)OPC=oropharyngeal candidiasis; SGOT=serum glutamic oxaloacetic transaminase (same as AST);SGPT=serum glutamic pyruvic transaminase (same as ALT).* Number of subjects reporting treatment-emergent adverse reactions at least once during the study,without regard to relationship to treatment. Subjects may have reported more than 1 event.Adverse reactions were reported more frequently in the pool of patients with refractory OPC. Among these highly immunocompromised patients with advanced HIV disease, serious adverse reactions (SARs) were reported in 55% (132/239). The most commonly reported SARs were fever (13%) and neutropenia (10%).Less Common Adverse Reactions: Clinically significant adverse reactions reported during clinical trials in prophylaxis, OPC/rOPC or other trials with posaconazole which occurred in less than 5% of patients are listed below:•Blood and lymphatic system disorders: hemolytic uremic syndrome, thrombotic thrombocytopenic purpura, neutropenia aggravated •Endocrine disorders: adrenal insufficiency•Nervous system disorders: paresthesia•Immune system disorders: allergic reaction [see Contraindications (4.1)]•Cardiac disorders: Torsades de pointes [see Warnings and Precautions (5.2)]•Vascular disorders: pulmonary embolism•Liver and Biliary System Disorders: bilirubinemia, hepatic enzymes increased, hepatic function abnormal, hepatitis, hepatomegaly, jaundice, SGOT Increased, SGPT Increased•Metabolic and Nutritional Disorders: Hypokalemia•Platelet, Bleeding, and Clotting Disorders: Thrombocytopenia•Renal & Urinary System Disorders: Renal Failure AcuteClinical Laboratory Values: In healthy volunteers and patients, elevation of liver function test values did not appear to be associated with higher plasma concentrations of posaconazole. The majority of abnormal liver function tests were minor, transient, and did not lead to discontinuation of therapy.For the prophylaxis studies, the number of patients with changes in liver function tests from Common Toxicity Criteria (CTC) Grade 0, 1, or 2 at baseline to Grade 3 or 4 during the study is presented in Table 3.TABLE 3: Study 1 and Study 2.

DRUG INTERACTIONSPosaconazole is primarily metabolized via UDP glucuronidation and is a substrate of p-glycoprotein efflux. Therefore, inhibitors or inducers of these clearance pathways may affect posaconazole plasma concentrations. Posaconazole is also a strong inhibitor of CYP3A4. Therefore, plasma concentrations of drugs predominantly metabolized by CYP3A4 may be increased by posaconazole [see Clinical Pharmacology (12.3)].7.1 Immunosuppressants Metabolized by CYP3A4Sirolimus: Concomitant administration of posaconazole with sirolimus increases the sirolimus blood concentrations by approximately 9 fold and can result in sirolimus toxicity. Therefore, posaconazole is contraindicated with sirolimus [see Contraindications (4.2) and Clinical Pharmacology (12.3)].Tacrolimus: Posaconazole has been shown to significantly increase the C max and AUC of tacrolimus. At initiation of posaconazole treatment, reduce the tacrolimus dose to approximately one-third of the original dose. Frequent monitoring of tacrolimus whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the tacrolimus dose adjusted accordingly [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3)].Cyclosporine: Posaconazole has been shown to increase cyclosporine whole blood concentrations in heart transplant patients upon initiation of posaconazole treatment. It is recommended to reduce cyclosporine dose to approximately three-fourths of the original dose upon initiation of posaconazole treatment. Frequent monitoring of cyclosporine whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the cyclosporine dose adjusted accordingly [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3)].7.2 CYP3A4 SubstratesConcomitant administration of posaconazole with CYP3A4 substrates such as pimozide and quinidine may result in increased plasma concentrations of these drugs, leading to QTc prolongation and rare occurrences of torsades de pointes. Therefore, posaconazole is contraindicated with these drugs. [see Contraindications (4.3), and Warnings and Precautions (5.2)].。
评价泊沙康唑预防血液系统疾病患者粒细胞缺乏期侵袭性真菌病的效果徐宵寒;张路;段明辉【摘要】目的评价泊沙康唑作为血液系统疾病患者粒细胞缺乏期侵袭性真菌病(IFD)预防用药的疗效和安全性.方法通过回顾性分析北京某院2014-2015年18例血液系统疾病患者在粒细胞缺乏期应用泊沙康唑单药预防IFD的病历,评价其疗效和安全性.结果 18例患者中,预防用药期间无1例出现临床诊断或确诊IFD,无1例因严重不良反应停用泊沙康唑.2例急性髓系白血病(AML)患者因肺部感染死亡,其中1例在预防用药第12天痰培养出嗜麦芽窄食单胞菌,另1例在预防用药第14天痰培养出大肠埃希菌.其余患者均坚持预防用药至粒细胞计数恢复,随访至预防用药100 d后无死亡.预防用药期间最低外周血中性粒细胞计数为(0.00~0.27)×109/L,中位数为0.02×109/L;泊沙康唑预防用药持续时间为8~27 d,中位数为16 d;无IFD突破以及合并全身性使用其他抗真菌药者,100日内全因死亡2例(11.1%);未出现2级及以上肝功能异常、2级及以上肾功能异常以及QTc延长等不良反应.结论应用泊沙康唑预防该组血液系统疾病患者粒细胞缺乏期IFD有效,也未出现严重不良反应.%Objective To evaluate the prophylactic efficacy and safety of posaconazole against invasive fungal disease(IFD)in hematologic patients with neutropenia.Methods Medical records of 18 hematologic patients with neutropenia received posaconazole for preventing IFD in a Beijing hospital between 2014 and 2015,the efficacy and safety was evaluated.Results There was no clinical diagnosis or confirmed diagnosis of IFD among 18 patients during posaconazole prophylaxis period,none of patients stopped posaconazole due to severe adverse reaction.Twopatients with acute myeloid leukemia(AML) died of pulmonary infection,1 of whom isolated Stenotrophomonas maltophilia from sputum culture on the 12th day of posaconazole prophylaxis,the other isolated Escherichia coli from sputum culture on the 14th day of posaconazole prophylaxis.Other patients all adherence to posaconazole prophylaxis until granulocyte count recovered,patients were followed up until 100 days medication,no death occurred.The lowest peripheral neutrophil count was(0.00-0.27) x 109/L during posaconazole prophylaxis period,with the median of 0.02 x 109/L;the duration of posaconazole prophylaxis was 8-27days,with the median of 16 days;among patients without IFD breakthrough or received systemic use of other antifungal agents,there were 2 (11.1%) all-cause death within 100 days;there were no adverse reaction,such as liver function abnormalities≥grade 2 and kidney function abnormalities≥grade 2,as well as QTc prolongation.Conclusion Posaconazole is effective for preventing IFD in hematologic patients with neutropenia,adverse reaction is rare.【期刊名称】《中国感染控制杂志》【年(卷),期】2017(016)001【总页数】5页(P32-35,57)【关键词】泊沙康唑;急性白血病;再生障碍性贫血;粒细胞缺乏;侵袭性真菌病;预防用药【作者】徐宵寒;张路;段明辉【作者单位】中国医学科学院北京协和医院,北京100730;中国医学科学院北京协和医院,北京100730;中国医学科学院北京协和医院,北京100730【正文语种】中文【中图分类】R519;R733侵袭性真菌病(invasive fungal disease,IFD)是血液系统疾病患者粒细胞缺乏(外周血中性粒细胞计数<0.5×109/L)期的主要并发症和致死原因之一[1],且近年来发生率呈升高趋势[2],IFD发生率与粒细胞缺乏期的持续时间以及宿主的免疫抑制程度相关[3],所以粒细胞缺乏期较长是IFD发生的高危因素,如急性白血病(acute leukemia,AL)诱导治疗期患者和重型再生障碍性贫血(severe aplastic anemia,SAA)患者。
新型抗真菌药简介当前真菌感染治疗面临很多挑战,侵袭性真菌感染死亡率居高不下、抗真菌药物的耐药性逐渐上升、多重耐药和高致死率的“超级真菌”的出现、抗真菌治疗疗程长、可选用的联合治疗方案有限以及抗真菌药物的安全性及药物相互作用问题等等。
再加上抗真菌药物的可及性相对较差,新型抗真菌药物具有巨大市场需求。
抗真菌药物近些年来有较好的发展,全球范围内新作用机制及新型抗真菌药物不断出现。
王明贵教授谈到,在中国,近年上市或即将上市的抗真菌药物也相对较多。
近年中国上市的抗真菌新药原研泊沙康唑在2022年之前的适应证为预防真菌感染,其混悬液、片剂和注射剂分别于2013、2018和2021年上市。
2022年3月原研泊沙康唑的片剂及注射剂被批准用于治疗侵袭性曲霉菌病。
国产泊沙康唑于2021年4月上市了片剂和注射剂,用于预防曲霉及念珠菌感染。
原研艾沙康唑胶囊于2021年12月被批准上市,用于治疗侵袭性曲霉病、毛霉病。
注射用艾沙康唑也于2022年6月获批上市。
除了艾沙康唑,毛霉病也可选择两性霉素B类进行药物治疗。
两性霉素B去氧胆酸盐不良反应较大,两性霉素B含脂制剂可使与输注相关的不良反应和肾毒性明显减少。
国产两性霉素B胆固醇硫酸酯复合物(ABCD)于2021年3月正式上市,用于治疗各类真菌病,同年该药进入医保国谈品种。
除此之外,原研脂质体两性霉素B(L-AMB)目前也处于审批当中。
正在进行或即将开展Ⅲ期临床试验的抗真菌新药目前也有一些其他药物在中国正在进行或者即将进入Ⅲ期临床试验中。
Rezafungin属于棘白菌素类药物,在国内的临床试验已经开展一段时间。
Ibrexafungerp(艾瑞芬净,IBX)作为首个全新三萜类结构的糖原合成酶抑制剂,其虽然为棘白菌素的衍生物,但IBX也可视为新作用机制的第四代抗真菌类药物。
IBX治疗念珠菌阴道炎疗效好,复发率低。
Fosmanogepix是一种新作用机制的抗真菌药物,对于曲霉病和毛霉病都可起到治疗效果,未来也将在中国开展临床试验。
泊沙康唑Noxafil(posaconazole)静脉注射剂
Merck的三唑抗真菌药泊沙康唑(posaconazole,Noxafil)静脉注射剂获得美国食品和药物管理局(FDA)批准。
此前,Noxafil的缓释片剂型已于2013年11月获FDA批准。
目前有两种剂型,分别为100mg缓释片和40mg/ml口服混悬液。
据了解,缓释片和口服混悬液剂型适用于13岁以上患者,而使用新的静脉用剂型患者要在18岁以上。
“Noxafil静脉剂型特别适用于需要静脉给药或者不能口服用药的患者。
而且,部分患者可在初始治疗时选用Noxafil注射剂,之后逐渐转为口服剂型等。
”Merck传染病研究室执行董事Nicholas Kartsonis表示。
Noxafil的获批,是基于一项药代动力学研究。
该项研究是一项非对照、多中心临床研究,在已发生或预期将发生显著中性粒细胞减少(neutropenia)的急性髓性系白血病(AML)或骨髓增生异常综合症(MDS)患者、以及已接受造血干细胞移植(HSCT)同时正接受免疫抑制治疗以预防移植物抗宿主病(GVHD)的患者中开展中,评价了Noxafil 的药代动力学、安全性和耐受性。
