《中国慢性淋巴细胞白血病小淋巴细胞淋巴瘤的诊断与治疗指南(完整版)》解读

《中国慢性淋巴细胞白血病小淋巴细胞淋巴瘤的诊断与治疗指南(完整版)》解读

《中国慢性淋巴细胞白血病/小淋巴细胞淋巴瘤的诊断与治疗指南(完整版)》解读近年,在慢性淋巴细胞白血病(CLL)的基础研究、新的预后标志、诊断标准及治疗等方面取得了巨大进展,为提高我国血液科医师对CLL诊断、鉴别诊断及规范化治疗水平,中国抗癌协会血液肿瘤专业委员会、中华医学会血液学分会和中国CLL工作组组织相关专家对2015年版CLL/小淋巴细胞淋巴瘤(SLL)的诊断与治疗指南进行了更新修订。

现就2018年版新修订指南进行解读。

一、诊断CLL和SLL均为单克隆、成熟样小淋巴细胞的淋巴系统恶性疾病,两者的区别在于CLL临床多表现为外周血和骨髓异常淋巴细胞浸润的白血病样表现;而SLL多为淋巴器官肿大的淋巴瘤样表现和骨髓受累。

(一)诊断标准CLL诊断要求外周血B淋巴细胞≥5×109/L;外周血B淋巴细胞必须经流式细胞术检查确认为克隆性,即细胞表面限制性表达免疫球蛋白的κ或λ轻链(sIgκ或sIgλ);另外,sIg阴性CD19细胞>25%也支持克隆性。

外周血涂片的形态学特征为成熟样小淋巴细胞(观察CLL细胞形态学外周血涂片优于骨髓涂片),这些细胞可能混有大而不典型的细胞、分裂细胞或<55%的幼稚淋巴细胞(简称幼淋细胞)。

如果外周血幼淋细胞占淋巴细胞的比例≥55%则诊断为幼淋细胞白血病(PLL),细胞形态学对诊断B-PLL至关重要;10%~54%则诊断为CLL/PL(CLL的一种变异型),幼淋细胞比例增高者预后不佳,同时需结合其他指标确认是否转化,特别是进行性增高时。

对于外周血存在克隆性B细胞,但B淋巴细胞绝对计数<5×109/L,同时不伴有淋巴结和器官肿大(所有淋巴结<1.5 cm)、血细胞减少和淋巴增殖性疾病相关症状的患者,应诊断为单克隆B淋巴细胞增多症(MBL);MBL大多CD5+,且呈典型的CLL表型,也可CD5-;CLL表型的MBL,根据外周血B淋巴细胞绝对计数分为低计数MBL(<0.5×109/L)及高计数MBL(≥0.5×109/L),前者进展为CLL的风险很小,无需常规随访,后者每年1%~2%进展为需要治疗的CLL,所以处理原则同早期CLL。

Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trials [see Clinical Studies (14.1)].1.2 Chronic Lymphocytic LeukemiaIMBRUVICA is indicated for the treatment of patients with chronic lymphocytic leukemia (CLL) who have received at least one prior therapy [see Clinical Studies (14.2)].1.3 Chronic Lymphocytic Leukemia with 17p deletionIMBRUVICA is indicated for the treatment of patients with chronic lymphocytic leukemia (CLL) with 17p deletion [see Clinical Studies (14.2)].1.4 Waldenström's MacroglobulinemiaIMBRUVICA is indicated for the treatment of patients with Waldenström's macroglobulinemia (WM) [see Clinical Studies (14.3)].2 DOSAGE AND ADMINISTRATION2.1 Dosing GuidelinesAdminister IMBRUVICA orally once daily at approximately the same time each day. Swallow the capsules whole with water. Do not open, break, or chew the capsules.2.2 DosageMantle Cell LymphomaThe recommended dose of IMBRUVICA for MCL is 560 mg (four 140 mg capsules) orally once daily. Chronic Lymphocytic Leukemia and Waldenström's MacroglobulinemiaThe recommended dose of IMBRUVICA for CLL and WM is 420 mg (three 140 mg capsules) orally once daily.2.3 Dose Modifications for Adverse ReactionsInterrupt IMBRUVICA therapy for any Grade 3 or greater non-hematological, Grade 3 or greaterneutropenia with infection or fever, or Grade 4 hematological toxicities. Once the symptoms of the toxicity have resolved to Grade 1 or baseline (recovery), IMBRUVICA therapy may be reinitiated at the starting dose. If the toxicity reoccurs, reduce dose by one capsule (140 mg per day). A second reduction of dose by 140 mg may be considered as needed. If these toxicities persist or recur following two dose reductions, discontinue IMBRUVICA.Recommended dose modifications are described below:Toxicity Occurrence MCL Dose Modification AfterRecoveryStarting Dose = 560 mgCLL and WM DoseModification After RecoveryStarting Dose = 420 mgFirst Restart at 560 mg daily Restart at 420 mg dailySecond Restart at 420 mg daily Restart at 280 mg dailyThird Restart at 280 mg daily Restart at 140 mg dailyFourth Discontinue IMBRUVICA Discontinue IMBRUVICA2.4 Dose Modifications for Use with CYP3A InhibitorsAvoid co-administration with strong or moderate CYP3A inhibitors and consider alternative agents with less CYP3A inhibition.Concomitant use of strong CYP3A inhibitors which would be taken chronically (e.g., ritonavir, indinavir, nelfinavir, saquinavir, boceprevir, telaprevir, nefazodone) is not recommended. For short-term use (treatment for 7 days or less) of strong CYP3A inhibitors (e.g., antifungals and antibiotics) consider interrupting IMBRUVICA therapy until the CYP3A inhibitor is no longer needed [see Drug Interactions (7.1)].Reduce IMBRUVICA dose to 140 mg if a moderate CYP3A inhibitor must be used (e.g., fluconazole, darunavir, erythromycin, diltiazem, atazanavir, aprepitant, amprenavir, fosamprevir, crizotinib, imatinib, verapamil, and ciprofloxacin) [see Drug Interactions (7.1)].Patients taking concomitant strong or moderate CYP3A inhibitors should be monitored more closely for signs of IMBRUVICA toxicity.2.5 Dose Modifications for Use in Hepatic ImpairmentFor patients with mild liver impairment (Child-Pugh class A), the recommended dose is 140 mg daily (one capsule). Avoid the use of IMBRUVICA in patients with moderate or severe hepatic impairment (Child-Pugh classes B and C) [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)]. 2.6 Missed DoseIf a dose of IMBRUVICA is not taken at the scheduled time, it can be taken as soon as possible on the same day with a return to the normal schedule the following day. Extra capsules of IMBRUVICA should not be taken to make up for the missed dose.3 DOSAGE FORMS AND STRENGTHS140 mg capsules4 CONTRAINDICATIONSNone5 WARNINGS AND PRECAUTIONS5.1 HemorrhageFatal bleeding events have occurred in patients treated with IMBRUVICA. Grade 3 or higher bleeding events (subdural hematoma, gastrointestinal bleeding, hematuria and post procedural hemorrhage) have occurred in up to 6% of patients. Bleeding events of any grade, including bruising and petechiae, occurred in approximately half of patients treated with IMBRUVICA.The mechanism for the bleeding events is not well understood.IMBRUVICA may increase the risk of hemorrhage in patients receiving antiplatelet or anticoagulant therapies.Consider the benefit-risk of withholding IMBRUVICA for at least 3 to 7 days pre and post-surgery depending upon the type of surgery and the risk of bleeding [see Clinical Studies (14)].5.2 InfectionsFatal and non-fatal infections have occurred with IMBRUVICA therapy. Grade 3 or greater infections occurred in 14% to 26% of patients. [See Adverse Reactions (6.1)]. Cases of progressive multifocal leukoencephalopathy (PML) have occurred in patients treated with IMBRUVICA. Monitor patients for fever and infections and evaluate promptly.5.3 CytopeniasTreatment-emergent Grade 3 or 4 cytopenias including neutropenia (range, 19 to 29%), thrombocytopenia (range, 5 to 17%), and anemia (range, 0 to 9%) occurred in patients treated with IMBRUVICA.Monitor complete blood counts monthly.5.4 Atrial FibrillationAtrial fibrillation and atrial flutter (range, 6 to 9%) have occurred in patients treated with IMBRUVICA, particularly in patients with cardiac risk factors, acute infections, and a previous history of atrial fibrillation. Periodically monitor patients clinically for atrial fibrillation. Patients who develop arrhythmic symptoms (e.g., palpitations, lightheadedness) or new onset dyspnea should have an ECG performed. If atrial fibrillation persists, consider the risks and benefits of IMBRUVICA treatment and dose modification [see Dosage and Administration (2.3)].5.5 Second Primary MalignanciesOther malignancies (range, 5 to 14%) including non-skin carcinomas (range, 1 to 3%) have occurred in patients treated with IMBRUVICA. The most frequent second primary malignancy was non-melanoma skin cancer (range, 4 to 11 %).5.6 Tumor Lysis SyndromeTumor lysis syndrome has been reported with IMBRUVICA therapy. Monitor patients closely and take appropriate precautions in patients at risk for tumor lysis syndrome (e.g. high tumor burden).5.7 Embryo-Fetal ToxicityBased on findings in animals, IMBRUVICA can cause fetal harm when administered to a pregnant woman. Ibrutinib caused malformations in rats at exposures 14 times those reported in patients with MCL and 20 times those reported in patients with CLL or WM, receiving the ibrutinib dose of 560 mg per day and 420 mg per day, respectively. Reduced fetal weights were observed at lower exposures. Advise women to avoid becoming pregnant while taking IMBRUVICA. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus [see Use in Specific Populations (8.1)].System Organ Class Preferred Term All Grades (%)Grade 3 or 4 (%)*Gastrointestinal disordersDiarrhea 634Constipation 232Nausea 212Stomatitis 210Vomiting192Abdominal pain 150Dyspepsia13Infections and infestations Upper respiratory tractinfection 482Sinusitis216Skin infection 176Pneumonia108Urinary tract infection100General disorders and administrative site conditions Fatigue 314Pyrexia 252Peripheral edema230Asthenia 134Chills130Skin and subcutaneous tissue disorders Bruising 542Rash270Petechiae170Respiratory, thoracic and mediastinal disorders Cough 190Oropharyngeal pain150Dyspnea100Musculoskeletal and connective tissue disorders Musculoskeletal pain 276Arthralgia230Muscle spasms192Nervous system disorders Dizziness210Headache192Peripheral neuropathy100Metabolism and nutritiondisordersDecreased appetite172Neoplasms benign,malignant, unspecified Second malignancies 100Injury, poisoning andprocedural complications Laceration102Psychiatric disorders Anxiety100Insomnia100Vascular disorders Hypertension178Table 4: Treatment-Emergent Decrease of Hemoglobin, Platelets, or Neutrophils inPatients with CLL (N=48) in Study 1Percent of Patients (N=48)All Grades (%)Grade 3 or 4 (%)Platelets Decreased7110One patient death due to histiocytic sarcoma.****Neutrophils Decreased 5427Hemoglobin Decreased 440Study 2Adverse reactions and laboratory abnormalities described below in Tables 5 and 6 reflect exposure to IMBRUVICA with a median duration of 8.6 months and exposure to ofatumumab with a median of 5.3months in Study 2.Table 5: Non-Hematologic Adverse Reactions ≥ 10% Reported in Study 2IMBRUVICA (N=195)Ofatumumab (N=191)System Organ Class ADRTermAll Grades (%)Grade 3 or 4(%)All Grades (%)Grade 3 or 4(%)Subjects with multiple events for a given ADR term are counted once only for each ADR term.Gastrointestinal disorders Diarrhea 484182 Nausea 262180 Stomatitis 17161 Constipation 15090 Vomiting 14061General disorders andadministration site conditions Fatigue 282302 Pyrexia 242151Infections and infestations Upper respiratory tractinfection 161112Pneumonia 1510139 Sinusitis 11160 Urinary tract infection 10451Skin and subcutaneous tissue disorders Rash 243130 Petechiae 14010 Bruising 12010Musculoskeletal andconnective tissue disorders Musculoskeletal Pain 282181 Arthralgia 17170Nervous system disorders Headache 14160 Dizziness 11050Injury, poisoning and procedural complications Contusion 11030Eye disorders Vision blurred 10030Based on laboratory measurements per IWCLL criteria and adverse reactions******The system organ class and individual ADR terms are sorted in descending frequency order.*Nervous system disorders Dizziness140Headache 130Neoplasms benign, malignant,and unspecified (including cysts and polyps)Skin cancer 110Table 8: Treatment-Emergent Decrease of Hemoglobin, Platelets, or Neutrophils inPatients with WM (N=63)Percent of Patients (N=63)All Grades (%)Grade 3 or 4 (%)*Platelets Decreased 4313Neutrophils Decreased 4419Hemoglobin Decreased1386. 2 Postmarketing ExperienceThe following adverse reactions have been identified during post-approval use of IMBRUVICA.Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.Hypersensitivity reactions including anaphylactic shock (fatal), urticaria, and angioedema have been reported.7 DRUG INTERACTIONSIbrutinib is primarily metabolized by cytochrome P450 enzyme 3A.7.1 CYP3A InhibitorsIn healthy volunteers, co-administration of ketoconazole, a strong CYP3A inhibitor, increased C and AUC of ibrutinib by 29- and 24-fold, respectively. The highest ibrutinib dose evaluated in clinical trials was 12.5 mg/kg (actual doses of 840 – 1400 mg) given for 28 days with single dose AUC values of 1445 ± 869 ng · hr/mL which is approximately 50% greater than steady state exposures seen at the highest indicated dose (560 mg).Avoid concomitant administration of IMBRUVICA with strong or moderate inhibitors of CYP3A. For strong CYP3A inhibitors used short-term (e.g., antifungals and antibiotics for 7 days or less, e.g.,ketoconazole, itraconazole, voriconazole, posaconazole, clarithromycin, telithromycin) considerinterrupting IMBRUVICA therapy during the duration of inhibitor use. Avoid strong CYP3A inhibitors that are needed chronically. If a moderate CYP3A inhibitor must be used, reduce the IMBRUVICA dose. Patients taking concomitant strong or moderate CYP3A4 inhibitors should be monitored more closely for signs of IMBRUVICA toxicity [see Dosage and Administration (2.4)].Avoid grapefruit and Seville oranges during IMBRUVICA treatment, as these contain moderate inhibitors of CYP3A [see Dosage and Administration (2.4), and Clinical Pharmacology (12.3)].7.2 CYP3A InducersAdministration of IMBRUVICA with rifampin, a strong CYP3A inducer, decreased ibrutinib C and AUC by approximately 13- and 10-fold, respectively.Avoid concomitant use of strong CYP3A inducers (e.g., carbamazepine, rifampin, phenytoin and St.John's Wort). Consider alternative agents with less CYP3A induction [see Clinical Pharmacology (12.3)].Includes multiple ADR terms.**Based on laboratory measurements.max max8 USE IN SPECIFIC POPULATIONS8.1 PregnancyPregnancy Category D [see Warnings and Precautions (5.7)].Risk SummaryBased on findings in animals, IMBRUVICA can cause fetal harm when administered to a pregnant woman. If IMBRUVICA is used during pregnancy or if the patient becomes pregnant while taking IMBRUVICA, the patient should be apprised of the potential hazard to the fetus.Animal DataIbrutinib was administered orally to pregnant rats during the period of organogenesis at oral doses of 10, 40 and 80 mg/kg/day. Ibrutinib at a dose of 80 mg/kg/day was associated with visceral malformations (heart and major vessels) and increased post-implantation loss. The dose of 80 mg/kg/day in animals is approximately 14 times the exposure (AUC) in patients with MCL and 20 times the exposure in patients with CLL or WM administered the dose of 560 mg daily and 420 mg daily, respectively. Ibrutinib at doses of 40 mg/kg/day or greater was associated with decreased fetal weights. The dose of 40 mg/kg/day in animals is approximately 6 times the exposure (AUC) in patients with MCL administered the dose of 560 mg daily.8.3 Nursing MothersIt is not known whether ibrutinib is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from IMBRUVICA, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.8.4 Pediatric UseThe safety and effectiveness of IMBRUVICA in pediatric patients has not been established.8.5 Geriatric UseOf the 111 patients treated for MCL, 63% were 65 years of age or older. No overall differences in effectiveness were observed between these patients and younger patients. Cardiac adverse events (atrial fibrillation and hypertension), infections (pneumonia and cellulitis) and gastrointestinal events (diarrhea and dehydration) occurred more frequently among elderly patients.Of the 391 patients randomized in Study 2, 61% were ≥ 65 years of age. No overall differences in effectiveness were observed between age groups. Grade 3 or higher adverse events occurred more frequently among elderly patients treated with IMBRUVICA (61% of patients age ≥ 65 versus 51% of younger patients) [see Clinical Studies (14.2)].Of the 63 patients treated for WM, 59% were 65 years of age or older. No overall differences in effectiveness were observed between these patients and younger patients. Cardiac adverse events (atrial fibrillation and hypertension), and infections (pneumonia and urinary tract infection) occurred more frequently among elderly patients.8.6 Renal ImpairmentLess than 1% of ibrutinib is excreted renally. Ibrutinib exposure is not altered in patients with Creatinine clearance (CLcr) > 25 mL/min. There are no data in patients with severe renal impairment (CLcr < 25 mL/min) or patients on dialysis [see Clinical Pharmacology (12.3)].8.7 Hepatic ImpairmentIbrutinib is metabolized in the liver. In a hepatic impairment study, data showed an increase in ibrutinib exposure. Following single dose administration, the AUC of ibrutinib increased 2.7-, 8.2- and 9.8-fold in subjects with mild (Child-Pugh class A), moderate (Child-Pugh class B), and severe (Child-Pugh class C) hepatic impairment compared to subjects with normal liver function. The safety of IMBRUVICA has not been evaluated in patients with hepatic impairment.Monitor patients for signs of IMBRUVICA toxicity and follow dose modification guidance as needed. It is not recommended to administer IMBRUVICA to patients with moderate or severe hepatic impairment (Child-Pugh classes B and C) [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3)].8.8 Females and Males of Reproductive PotentialAdvise women to avoid becoming pregnant while taking IMBRUVICA because IMBRUVICA can cause fetal harm [see Use in Specific Populations (8.1)].8.9 PlasmapheresisManagement of hyperviscosity in patients with WM may include plasmapheresis before and during treatment with IMBRUVICA. Modifications to IMBRUVICA dosing are not required.11 DESCRIPTIONIbrutinib is an inhibitor of Bruton's tyrosine kinase (BTK). It is a white to off-white solid with the empirical formula C25H24N6O2 and a molecular weight 440.50. Ibrutinib is freely soluble in dimethyl sulfoxide, soluble in methanol and practically insoluble in water.The chemical name for ibrutinib is 1-[(3R)-3-[4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-1-piperidinyl]-2-propen-1-one and has the following structure:IMBRUVICA (ibrutinib) capsules for oral administration are supplied as white opaque capsules that contain 140 mg ibrutinib as the active ingredient. Each capsule also contains the following inactive ingredients: croscarmellose sodium, magnesium stearate, microcrystalline cellulose, sodium lauryl sulfate. The capsule shell contains gelatin, titanium dioxide and black ink. Each white opaque capsule is marked with "ibr 140 mg" in black ink.12 CLINICAL PHARMACOLOGY12.1 Mechanism of ActionIbrutinib is a small-molecule inhibitor of BTK. Ibrutinib forms a covalent bond with a cysteine residue in the BTK active site, leading to inhibition of BTK enzymatic activity. BTK is a signaling molecule of the B-cell antigen receptor (BCR) and cytokine receptor pathways. BTK's role in signaling through the B-cell surface receptors results in activation of pathways necessary for B-cell trafficking, chemotaxis,and adhesion. Nonclinical studies show that ibrutinib inhibits malignant B-cell proliferation and survival in vivo as well as cell migration and substrate adhesion in vitro.12.2 PharmacodynamicsIn patients with recurrent B-cell lymphoma > 90% occupancy of the BTK active site in peripheral blood mononuclear cells was observed up to 24 hours after ibrutinib doses of ≥ 2.5 mg/kg/day (≥ 175 mg/day for average weight of 70 kg).12.3 PharmacokineticsAbsorptionIbrutinib is absorbed after oral administration with a median T of 1 to 2 hours. Ibrutinib exposure increases with doses up to 840 mg. The steady-state AUC (mean ± standard deviation) observed in patients at 560 mg is 953 ± 705 ng·h/mL and in patients at 420 mg is 680 ± 517 ng·h/mL. Administration with food increased ibrutinib C and AUC by approximately 2 to 4- and 2-fold, respectively,compared with administration of ibrutinib after overnight fasting.DistributionReversible binding of ibrutinib to human plasma protein in vitro was 97.3% with no concentration dependence in the range of 50 to 1000 ng/mL. The volume of distribution at steady state (V ) was 683L, and the apparent volume of distribution at steady state (V /F) was approximately 10000 L.MetabolismMetabolism is the main route of elimination for ibrutinib. It is metabolized to several metabolitesprimarily by cytochrome P450, CYP3A, and to a minor extent by CYP2D6. The active metabolite, PCI-45227, is a dihydrodiol metabolite with inhibitory activity towards BTK approximately 15 times lower than that of ibrutinib. The range of the mean metabolite to parent ratio for PCI-45227 at steady-state is 1to 2.8.EliminationIntravenous clearance was 62 and 76 L/h in fasted and fed conditions, respectively. In line with the high first-pass effect, the apparent oral clearance is approximately 2000 and 1000 L/h in fasted and fed conditions, respectively. The half-life of ibrutinib is 4 to 6 hours.Ibrutinib, mainly in the form of metabolites, is eliminated primarily via feces. After a single oraladministration of radiolabeled [C]-ibrutinib in healthy subjects, approximately 90% of radioactivity was excreted within 168 hours, with the majority (80%) excreted in the feces and less than 10%accounted for in urine. Unchanged ibrutinib accounted for approximately 1% of the radiolabeled excretion product in feces and none in urine, with the remainder of the dose being metabolites.AgeAge (37 to 84 years) does not alter ibrutinib systemic clearance.GenderGender does not alter ibrutinib systemic clearance.Renal ImpairmentIbrutinib is not significantly cleared renally; urinary excretion of metabolites is < 10% of the dose.max max d,ss d,ss 14Creatinine clearance > 25 mL/min had no influence on the exposure to IMBRUVICA. There are no data in patients with severe renal impairment (CLcr < 25 mL/min) or in patients on dialysis.Hepatic ImpairmentIbrutinib is metabolized in the liver. In a hepatic impairment trial, a single dose of 140 mg ofIMBRUVICA was administered in non-cancer subjects. Ibrutinib AUC increased 2.7-, 8.2- and 9.8-fold,respectively, in subjects with mild (n=6), moderate (n=10) and severe (n=8) hepatic impairment relative to subjects with normal liver function. Ibrutinib C increased 5.2-, 8.8- and 7.0-fold, respectively, in subjects with mild, moderate and severe hepatic impairment relative to subjects with normal liver function [see Use in Specific Populations (8.7)].Drug InteractionsCoadministration of Ibrutinib with CYP3A InhibitorsIn a sequential design trial of 18 healthy, fasted volunteers, a single dose of 120 mg of IMBRUVICA was administered alone on Day 1 and a single dose of 40 mg of IMBRUVICA was administered on Day 7 in combination with 400 mg of ketoconazole (given daily on Days 4 – 9). Ketoconazole increased ibrutinib dose-normalized C and AUC 29-fold and 24-fold, respectively. Simulations using fasted conditions indicate that moderate CYP3A inhibitors diltiazem and erythromycin may increase AUC of ibrutinib by 5- to 8-fold.Coadministration of Ibrutinib with CYP3A InducersPK data from a dedicated drug interaction trial showed that rifampin (a strong CYP3A inducer)decreases ibrutinib C and AUC by more than 13- and 10-fold. Simulations using PBPK suggested that a moderate CYP3A inducer (efavirenz) may decrease the AUC of ibrutinib by up to 3-fold.Coadministration of Ibrutinib with CYP SubstratesIn vitro studies indicated that ibrutinib (I/Ki < 0.07 using mean C at 560 mg) and PCI-45227 (I/Ki <0.03) are unlikely to be inhibitors of any major CYPs at clinical doses. Both ibrutinib and the PCI-45227are weak inducers of CYP450 isoenzymes in vitro.Coadministration of Ibrutinib with Substrates of TransportersIn vitro studies indicated that ibrutinib is not a substrate of p-glycoprotein (P-gp). Systemic ibrutinib is unlikely to be an inhibitor of P-gp at clinical doses ([I]/Ki < 0.1). However, it may have an effect on P-gp substrates in the GI tract due to higher local concentrations after an oral dose. Co-administration of oral narrow therapeutic index P-gp substrates (e.g., digoxin) with IMBRUVICA may increase their blood concentration.13 NONCLINICAL TOXICOLOGY13.1 Carcinogenesis, Mutagenesis, Impairment of FertilityCarcinogenicity studies have not been conducted with ibrutinib.Ibrutinib was not mutagenic in a bacterial mutagenicity (Ames) assay, was not clastogenic in a chromosome aberration assay in mammalian (CHO) cells, nor was it clastogenic in an in vivo bone marrow micronucleus assay in mice at doses up to 2000 mg/kg.Fertility studies with ibrutinib have not been conducted in animals. In the general toxicology studies conducted in rats and dogs, orally administered ibrutinib did not result in adverse effects onreproductive organs.14 CLINICAL STUDIES14.1 Mantle Cell Lymphomamax max max max 1The safety and efficacy of IMBRUVICA in patients with MCL who have received at least one prior therapy were evaluated in an open-label, multi-center, single-arm trial of 111 previously treated patients. The median age was 68 years (range, 40 to 84 years), 77% were male, and 92% were Caucasian. At baseline, 89% of patients had a baseline ECOG performance status of 0 or 1. The median time since diagnosis was 42 months, and median number of prior treatments was 3 (range, 1 to 5 treatments), including 11% with prior stem cell transplant. At baseline, 39% of subjects had at least one tumor ≥ 5 cm, 49% had bone marrow involvement, and 54% had extranodal involvement at screening. IMBRUVICA was administered orally at 560 mg once daily until disease progression or unacceptable toxicity. Tumor response was assessed according to the revised International Working Group (IWG) for non-Hodgkin's lymphoma (NHL) criteria. The primary endpoint in this study was investigator-assessed overall response rate (ORR). Responses to IMBRUVICA are shown in Table 9.Table 9: Overall Response Rate (ORR) and Duration of Response (DOR)Based on Investigator Assessment in Patients with MCLTotal (N=111)ORR (%)65.895% CI (%)(56.2, 74.5)CR (%)17.1PR (%)48.6Median DOR months (95% CI)17.5 (15.8, NR)CI = confidence interval; CR = complete response; PR = partial response; NR =not reachedAn Independent Review Committee (IRC) performed independent reading and interpretation of imaging scans. The IRC review demonstrated an ORR of 69%.The median time to response was 1.9 months.LymphocytosisUpon initiation of IMBRUVICA, a temporary increase in lymphocyte counts (i.e., ≥ 50% increase from baseline and above absolute lymphocyte count of 5,000/mcL) occurred in 33% of patients in the MCL study. The onset of isolated lymphocytosis occurs during the first few weeks of IMBRUVICA therapy and resolves by a median of 8 weeks.14.2 Chronic Lymphocytic LeukemiaThe safety and efficacy of IMBRUVICA in patients with CLL who have received at least one prior therapy were demonstrated in one uncontrolled trial and one randomized, controlled trial.Study 1An open-label, multi-center trial was conducted in 48 previously treated CLL patients. The median age was 67 years (range, 37 to 82 years), 71% were male, and 94% were Caucasian. All patients had a baseline ECOG performance status of 0 or 1. The median time since diagnosis was 80 months and the median number of prior treatments was 4 (range, 1 to 12 treatments). At baseline, 46% of subjects had at least one tumor ≥ 5 cm.IMBRUVICA was administered orally at 420 mg once daily until disease progression or unacceptable toxicity. The ORR and DOR were assessed using a modified version of the International Workshop on CLL Criteria by an Independent Review Committee. The ORR was 58.3% (95% CI: 43.2%, 72.4%), all partial responses. None of the patients achieved a complete response. The DOR ranged from 5.6 to 24.2+ months. The median DOR was not reached.Study 2。

伊布替尼的耐药机制

伊布替尼的耐药机制

1.BTK突变Bruton酪氨酸激酶(BTK)是一种非受体酪氨酸激酶,在B细胞受体(BCR)信号传导通路中起到关键作用,促使B细胞的生长和存活[1]。

伊布替尼作为一种BTK抑制剂,能有效抑制BTK的活性,从而对慢性淋巴细胞白血病(CLL)具有显著的治疗效果[2]。

然而,耐药现象已经成为一个临床难题。

研究发现,耐药CLL患者体内的BTK基因发生了突变,其中最常见的是C481S突变[3]。

这种突变使得伊布替尼与BTK的结合受到阻碍,从而降低了药物的疗效。

另外,还发现了其他一些较少见的BTK突变,如T316A和T474I等[4]。

针对BTK突变导致的耐药问题,研究者尝试开发新型BTK抑制剂,如ACP-196和ONO/GS-4059等,这些药物对C481S突变具有抑制作用,并在临床试验中取得了一定的疗效[5][6]。

为了充分了解BTK突变导致耐药的机制,研究者还在探索其他与BTK突变相关的信号通路,如PLCγ2、PI3K/Akt/mTOR和NF-κB等信号通路[7][8]。

这些信号通路在B细胞生存、增殖和抗凋亡中发挥关键作用,可能与伊布替尼耐药性的产生有关。

研究者还关注到非BTK突变引起的耐药机制,如信号通路相关基因突变、细胞表面受体改变等[9]。

这些非BTK突变的耐药机制可能与BTK突变共同作用,导致伊布替尼的治疗效果减弱。

BTK突变是伊布替尼耐药的重要原因之一,深入研究BTK突变和其他信号通路在耐药性中的作用,将有助于开发新型BTK抑制剂和优化慢性淋巴细胞白血病的治疗策略。

2.B细胞克隆演化慢性淋巴细胞白血病(CLL)的发展和进展是一个克隆演化的过程,其中患者体内的B细胞在治疗压力下不断演化和适应,导致耐药性的产生。

研究发现,CLL患者体内存在多个亚克隆(subclone),它们在治疗过程中通过竞争和选择逐渐产生抗药性亚克隆[10]。

Dan等人(2013)对一系列CLL患者进行了基因组测序,发现在伊布替尼治療過程中,部分患者体内的耐药亚克隆逐渐扩增,导致治疗失败[11]。

伊布替尼汇聚式合成策略

核心结构通常包含多个芳香环和其他功能基团。

合成核心结构可以通过各种有机合成反应,如芳香化反应、羧酸衍生物的合成等。

2.功能基团的引入:接下来,在核心结构上引入特定的功能基团,这些功能基团对于药物的活性和选择性至关重要。

引入功能基团可以通过不同的官能团化反应,如亲核取代、还原反应、酯化等。

3.保护基团的应用:在合成过程中,可能需要在特定位置引入保护基团,以防止意外反应或保护化合物的特定官能团。

保护基团可以在适当的时机通过特定的保护反应引入,并在需要时通过去保护反应去除。

4.连接和最后步骤:在完成核心结构和功能基团的合成后,将它们连接在一起,并进行最后的化学转化步骤。

这可能包括环合反应、缩合反应、纯化和晶体化等步骤。

伊布替尼的汇聚式合成策略是一个复杂而精细的有机合成过程,需要合成化学家运用多种有机合成技术和策略,以高产率和高纯度合成目标化合物。

这样的合成方法在药物研发中具有重要的意义,可以为大规模生产提供可靠的合成路线。

注:MCL为套细胞淋巴瘤,CLL为慢性淋巴细胞白血病,WM为华氏巨球蛋白血症。

五、药物冲突与剂量调整
1、CYP3A抑制药
禁止与CYP3A 强抑制剂共同给药,如必须使用CYP3A 强抑制剂,则中断伊布替尼用药,;中度CYP3A抑制剂必须使用时,降低伊布替尼使用剂量至140毫克。

当CYP3A抑制药与伊布替尼共同使用时,密切观察使用者的不良反应。

在可以使用CYP3A 抑制作用较小的代替药物时,不要使用强或中抑制剂。

2、CYP3A诱导剂
CYP3A诱导剂会降低伊布替尼的血浆浓度,不宜与伊布替尼共同给药,如必须使用时,请选择较弱的CYP3A 诱导剂。

3、呋喃香豆素
呋喃香豆素天然存在于柑橘类水果中,该成分会抑制人体内分解药物的酶活性,从而导致进入血液的药量倍增,服用伊布替尼期间不用食用柑橘、柠檬类水果。

温情提示
作为抗癌靶向药物,伊布替尼的使用应谨遵医嘱,患者切不可凭一己之见、依靠对药物说明书的理解来解决问题,任何突发性情况或疑问都应联系主治医师予以应对。
