Hepatic function should be monitored closely with both clinical andlaboratory follow-up for at least several months in patients who discontinueanti-hepatitis B therapy, including VIREAD. If appropriate, resumption ofanti-hepatitis B therapy may be warranted [See Warnings and Precautions(5.2)].1 INDICATIONS AND USAGEInfection1.1 HIV-1VIREAD® is indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in adults and pediatric patients 12 years of age and older.The following points should be considered when initiating therapy with VIREAD for the treatment of HIV-1 infection:• VIREAD should not be used in combination with TRUVADA® or ATRIPLA® [See Warnings and Precautions (5.4)].1.2 Chronic Hepatitis BVIREAD is indicated for the treatment of chronic hepatitis B in adults.The following points should be considered when initiating therapy with VIREAD for the treatment of HBV infection:• This indication is based primarily on data from treatment of subjects who were nucleoside-treatment-naïve and a smaller number of subjects who had previously received lamivudine or adefovir dipivoxil. Subjects were adults with HBeAgpositive and HBeAg-negative chronic hepatitis B with compensated liver disease [See Clinical Studies (14.2)].• VIREAD was evaluated in a limited number of subjects with chronic hepatitis B and decompensated liver disease. [See Adverse Reactions (6.1), Clinical Studies(14.2)]• The numbers of subjects in clinical trials who had lamivudine- or adefovirassociated substitutions at baseline were too small to reach conclusions ofefficacy [See Microbiology (12.4), Clinical Studies (14.2)].2 DOSAGE AND ADMINISTRATION2.1 Recommended Dose in AdultsFor the treatment of HIV-1 or chronic hepatitis B: The dose is one 300 mg VIREAD tablet once daily taken orally, without regard to food.In the treatment of chronic hepatitis B, the optimal duration of treatment is unknown.2.2 Recommended Dose in Pediatric Patients (≥12 Years of Age and ≥35 kg) For the treatment of HIV-1 in pediatric patients 12 years of age and older with body weight ≥35 kg (≥77 lb): The dose is one 300 mg VIREAD tablet once daily taken orally, without regard to food.2.3 Dose Adjustment for Renal Impairment in AdultsSignificantly increased drug exposures occurred when VIREAD was administered to subjects with moderate to severe renal impairment [See Clinical Pharmacology (12.3)]. Therefore, the dosing interval of VIREAD should be adjusted in patients with baseline creatinine clearance <50 mL/min using the recommendations in Table 1. These dosing interval recommendations are based on modeling of single-dose pharmacokinetic data in non-HIV and non-HBV infected subjects with varying degrees of renal impairment, including end-stage renal disease requiring hemodialysis. The safety and effectiveness of these dosing interval adjustment recommendations have not been clinically evaluated in patients with moderate or severe renal impairment, therefore clinical response to treatment and renal function should be closely monitored in these patients [See Warnings and Precautions (5.3)].No dose adjustment is necessary for patients with mild renal impairment (creatinine clearance 50–80 mL/min). Routine monitoring of calculated creatinine clearance and serum phosphorus should be performed in patients with mild renal impairment [See Warnings and Precautions (5.3)].Table 1 Dosage Adjustment for Patients with Altered Creatinine ClearanceCreatinine Clearance(mL/min)aHemodialysis Patients≥50 30–49 10–29Recommended 300 mg Dosing Interval Every 24hoursEvery 48hoursEvery 72 to96 hoursEvery 7 days or after a total ofapproximately 12 hours ofdialysis ba. Calculated using ideal (lean) body weight.b. Generally once weekly assuming three hemodialysis sessions a week of approximately 4 hours duration.VIREAD should be administered following completion of dialysis.The pharmacokinetics of tenofovir have not been evaluated in non-hemodialysis patients with creatinine clearance <10 mL/min; therefore, no dosing recommendation is available for these patients.No data are available to make dose recommendations in pediatric patients 12 years of age and older with renal impairment.3 DOSAGE FORMS AND STRENGTHSVIREAD is available as tablets. Each tablet contains 300 mg of tenofovir disoproxil fumarate, which is equivalent to 245 mg of tenofovir disoproxil. The tablets are almond-shaped, light blue, film-coated, and debossed with “GILEAD” and “4331” on one side and with “300” on the other side.4 CONTRAINDICATIONSNone.5 WARNINGS AND PRECAUTIONS5.1 Lactic Acidosis/Severe Hepatomegaly with SteatosisLactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogs, including VIREAD, in combination with other antiretrovirals. A majority of these cases have been in women. Obesity and prolonged nucleoside exposure may be risk factors. Particular caution should be exercised when administering nucleoside analogs to any patient with known risk factors for liver disease; however, cases have also been reported in patients with no known risk factors. Treatment with VIREAD should be suspended in any patient who develops clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity (which may include hepatomegaly and steatosis even in the absence of marked transaminase elevations).5.2 Exacerbation of Hepatitis after Discontinuation of Treatment Discontinuation of anti-HBV therapy, including VIREAD, may be associated with severe acute exacerbations of hepatitis. Patients infected with HBV who discontinue VIREAD should be closely monitored with both clinical and laboratory follow-up for at least several months after stopping treatment. If appropriate, resumption of anti-hepatitis B therapy may be warranted.5.3 New Onset or Worsening Renal ImpairmentTenofovir is principally eliminated by the kidney. Renal impairment, including cases of acute renal failure and Fanconi syndrome (renal tubular injury with severe hypophosphatemia), has been reported with the use of VIREAD [See Adverse Reactions (6.2)].It is recommended that creatinine clearance be calculated in all patients prior to initiating therapy and as clinically appropriate during therapy with VIREAD. Routine monitoring of calculated creatinine clearance and serum phosphorus should be performed in patients at risk for renal impairment, including patients who have previously experienced renal events while receiving HEPSERA®.Dosing interval adjustment of VIREAD and close monitoring of renal function are recommended in all patients with creatinine clearance <50 mL/min [See Dosage and Administration (2.3)]. No safety or efficacy data are available in patients with renal impairment who received VIREAD using these dosing guidelines, so the potential benefit of VIREAD therapy should be assessed against the potential risk of renal toxicity.VIREAD should be avoided with concurrent or recent use of a nephrotoxic agent.5.4 Coadministration with Other ProductsVIREAD should not be used in combination with the fixed-dose combination products TRUVADA or ATRIPLA since tenofovir disoproxil fumarate is a component of these products.VIREAD should not be administered in combination with HEPSERA (adefovir dipivoxil) [See Drug Interactions (7.4)].Coinfected with HIV-1 and HBV5.5 PatientsDue to the risk of development of HIV-1 resistance, VIREAD should only be used in HIV-1 and HBV coinfected patients as part of an appropriate antiretroviral combination regimen.HIV-1 antibody testing should be offered to all HBV-infected patients before initiating therapy with VIREAD. It is also recommended that all patients with HIV-1 be tested for the presence of chronic hepatitis B before initiating treatment with VIREAD.5.6 Decreases in Bone Mineral DensityAssessment of bone mineral density (BMD) should be considered for adults and pediatric patients 12 years of age and older who have a history of pathologic bone fracture or other risk factors for osteoporosis or bone loss. Although the effect of supplementation with calcium and vitamin D was not studied, such supplementation may be beneficial for all patients. If bone abnormalities are suspected then appropriate consultation should be obtained.In HIV-1 infected adult subjects treated with VIREAD in Study 903 through 144 weeks, decreases from baseline in BMD were seen at the lumbar spine and hip in both arms of the study. At Week 144, there was a significantly greater mean percentage decrease from baseline in BMD at the lumbar spine in subjects receiving VIREAD + lamivudine + efavirenz (-2.2% ± 3.9) compared with subjects receiving stavudine + lamivudine + efavirenz (-1.0% ± 4.6). Changes in BMD at the hip were similar between the two treatment groups (-2.8% ± 3.5 in the VIREAD group vs. -2.4% ± 4.5 in the stavudine group). In both groups, the majority of the reduction in BMD occurred in the first 24–48 weeks of the study and this reduction was sustained through Week 144. Twenty-eightpercent of VIREAD-treated subjects vs. 21% of the stavudine-treated subjects lost at least 5% of BMD at the spine or 7% of BMD at the hip. Clinically relevant fractures (excluding fingers and toes) were reported in 4 subjects in the VIREAD group and 6 subjects in the stavudine group. In addition, there were significant increases in biochemical markers of bone metabolism (serum bone-specific alkaline phosphatase, serum osteocalcin, serum C-telopeptide, and urinary N-telopeptide) in the VIREAD group relative to the stavudine group, suggesting increased bone turnover. Serum parathyroid hormone levels and 1,25 Vitamin D levels were also higher in the VIREAD group. Except for bone specific alkaline phosphatase, these changes resulted in values that remained within the normal range.In a clinical study of HIV-1 infected pediatric subjects 12 years of age and older (Study 321), bone effects were similar to adult subjects. Under normal circumstances BMD increases rapidly in this age group. In this study, the mean rate of bone gain was less in the VIREAD-treated group compared to the placebo group. Six VIREAD treated subjects and one placebo treated subject had significant (>4%) lumbar spine BMD loss in 48 weeks. Among 28 subjects receiving 96 weeks of VIREAD, Z-scores declined by -0.341 for lumbar spine and -0.458 for total body. Skeletal growth (height) appeared to be unaffected. Markers of bone turnover in VIREAD-treated pediatric subjects 12 years of age and older suggest increased bone turnover, consistent with the effects observed in adults.The effects of VIREAD-associated changes in BMD and biochemical markers on long-term bone health and future fracture risk are unknown.Cases of osteomalacia (associated with proximal renal tubulopathy and which may contribute to fractures) have been reported in association with the use of VIREAD [See Adverse Reactions (6.2)].The bone effects of VIREAD have not been studied in patients with chronic HBV infection.Redistribution5.7 FatIn HIV-infected patients redistribution/accumulation of body fat including central obesity, dorsocervical fat enlargement (buffalo hump), peripheral wasting, facial wasting, breast enlargement, and "cushingoid appearance" have been observed in patients receiving combination antiretroviral therapy. The mechanism and long-term consequences of these events are currently unknown. A causal relationship has not been established. 5.8 Immune Reconstitution SyndromeImmune reconstitution syndrome has been reported in HIV-infected patients treated with combination antiretroviral therapy, including VIREAD. During the initial phase of combination antiretroviral treatment, patients whose immune system responds may develop an inflammatory response to indolent or residual opportunistic infections [such as Mycobacterium avium infection, cytomegalovirus, Pneumocystis jirovecii pneumonia (PCP), or tuberculosis], which may necessitate further evaluation and treatment.5.9 Early Virologic FailureClinical studies in HIV-infected subjects have demonstrated that certain regimens that only contain three nucleoside reverse transcriptase inhibitors (NRTI) are generally less effective than triple drug regimens containing two NRTIs in combination with either a non-nucleoside reverse transcriptase inhibitor or a HIV-1 protease inhibitor. In particular, early virological failure and high rates of resistance substitutions have been reported. Triple nucleoside regimens should therefore be used with caution. Patients on a therapy utilizing a triple nucleoside-only regimen should be carefully monitored and considered for treatment modification.6 ADVERSEREACTIONSThe following adverse reactions are discussed in other sections of the labeling:• Lactic Acidosis/Severe Hepatomegaly with Steatosis [See Boxed Warning, Warnings and Precautions (5.1)].• Severe Acute Exacerbation of Hepatitis [See Boxed Warning, Warnings and Precautions (5.2)].• New Onset or Worsening Renal Impairment [See Warnings and Precautions (5.3)]. • Decreases in Bone Mineral Density [See Warnings and Precautions (5.6)].• Immune Reconstitution Syndrome [See Warnings and Precautions (5.8)].6.1 Adverse Reactions from Clinical Trials ExperienceBecause clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.Clinical Trials in Adult Patients with HIV-1 InfectionMore than 12,000 subjects have been treated with VIREAD alone or in combination with other antiretroviral medicinal products for periods of 28 days to 215 weeks in clinical trials and expanded access studies. A total of 1,544 subjects have received VIREAD 300 mg once daily in clinical trials; over 11,000 subjects have received VIREAD in expanded access studies.The most common adverse reactions (incidence ≥10%, Grades 2–4) identified from any of the 3 large controlled clinical trials include rash, diarrhea, headache, pain, depression, asthenia, and nausea.Treatment-Naïve PatientsStudy 903 - Treatment-Emergent Adverse Reactions: The most common adverse reactions seen in a double-blind comparative controlled study in which 600 treatment-naïve subjects received VIREAD (N=299) or stavudine (N=301) in combination with lamivudine and efavirenz for 144 weeks (Study 903) were mild to moderate gastrointestinal events and dizziness.Mild adverse reactions (Grade 1) were common with a similar incidence in both arms, and included dizziness, diarrhea, and nausea.

B,CHB)是由乙型肝炎病毒(HBV)持续感染引起的慢性肝脏炎症性疾病.全球约有三分之一人口曾感染HBV,其中2.4亿人为慢性HBV感染者.据世界卫生组织(WHO)报道,全球30%的肝硬化患者和50%肝癌患者都由HBV感染所致,2013年,全球约有68万人死于HBV感染,HBV感染已经成为全球公认的重大健康问题[1-3].半富马酸替诺福韦艾拉酚胺(tenofovir alafenamide humifumarate,TAF)是一种治疗乙肝的新型核苷逆转录酶抑制剂,尚未在中国上市及进口[4].TAF是富马酸替诺福韦酯(TDF)的新一代替诺福韦(PMAP)口服前药,TAF的Ⅲ期临床试验数据显示,25 mg的TAF与300 mg现有的抗乙肝一线药物TDF的抗乙肝病毒效果相当,且TAF对肾和骨骼的毒性更小,安全性更好[5-6],是目前疗效最好的核苷类乙肝药物.文献中报道的TAF合成路线主要有4条[7-15].TAF的合成路线需经过中间体(R)-9-(2-羟丙基)腺嘌呤或(R)-9-[2-(膦酰基甲氧基)丙基]腺嘌呤,并以此为二次原料,经过数步反应制得TAF.但现有的合成方法存在目标产物收率低,反应后处理程序繁多,合成成本高,工业生产效率低,存在安全性问题等缺点,不适合工业化放大生产.因此,本文选择对吉利德公司的原研路线[9]进行优化,以腺嘌呤为起始原料,与(R)-碳酸丙烯酯反应得到(R)-9-(2-羟丙基)腺嘌呤;然后,经磷叶立德取代、水解反应得到(R)-9-(((2-磷酸单苯酯基)甲氧基)丙基)-腺嘌呤,再经取代、酰化、缩合、成盐反应制备得到TAF.1

(R)-9-(2-羟丙基)腺嘌呤反应的合成机理是腺嘌呤在碱性条件下形成氮负离子,从而进攻(R)-碳酸丙烯酯上正电荷密集的碳原子,促使其脱去一分子二氧化碳;接着,腺嘌呤上的氮负离子和碳原子链接后形成带有氧负离子的(R)-9-(2-羟丙基)腺嘌呤;最后,该氧负离子与一分子腺嘌呤反应生成一分子(R)-9-(2-羟丙基)腺嘌呤和一分子腺嘌呤氮负离子.其中,氢氧化钠在该反应中起催化作用,有利于腺嘌呤脱去氢离子从而进攻(R)-碳酸丙烯酯上的碳原子促使反应发生.通过分析反应机理和前期实验得知,n(腺嘌呤)∶n((R)-碳酸丙烯酯)和n(氢氧化钠)∶n(腺嘌呤)对实验收率有较大影响,n为物质的量.因此,通过单因素考察实验分别考察n(腺嘌呤)∶n((R)-碳酸丙烯酯)和n(氢氧化钠)∶n(腺嘌呤)对(R)-9-(2-羟丙基)腺嘌呤收率的影响,结果如图11,12所示.图11

of compound 2由图11可知:腺嘌呤与(R)-碳酸丙烯酯的物质的量的比对化合物2的收率有较为突出的影响;当n(腺嘌呤)∶n((R)-碳酸丙烯酯)为1.0∶1.0~1.0∶1.3时,收率随着比值的增大而增加;当n(腺嘌呤)∶n((R)-碳酸丙烯酯)为1.0∶1.3时,收率达最大值81.7%,而后趋于平稳.由图12可知:n(氢氧化钠)∶n(腺嘌呤)对中间体7收率影响较大,当n(氢氧化钠)∶n(腺嘌呤)为1∶25~1∶15时,收率随着比值的减小而增加;当n(氢氧化钠)∶n(腺嘌呤)为1∶15时,收率达到最大值91.6%,而后逐渐减小.由实验可知,当n(腺嘌呤)∶n((R)-碳酸丙烯酯)为1.0∶1.3,n(氢氧化钠)∶n(腺嘌呤)为1∶15时,反应收率达最大值91.6%.2.2

4该反应机理为三甲基溴硅烷(TMBS)与(R)-9-[2-(二乙酰氧基膦酰基甲氧基)丙基]腺嘌呤上发生亲电取代反应后,水解生成三甲基硅醇和(R)-9-[2-(膦酰基甲氧基)丙基]腺嘌呤.由反应机理可知,反应溶剂和脱烷基化试剂三甲基溴硅烷在反应中起重要作用,因此,单因素考察n(化合物3)∶n(三甲基溴硅烷)对化合物4收率的影响,如图13所示.由图13可知:n(化合物3)∶n(三甲基溴硅烷)对反应收率的影响较大;当比值为1∶3时,反应收率达最大值59.4%.推测可能是因为溶剂中含有较多水,使部分三甲基溴硅烷水解失去脱烷基化作用.因此,增加三甲基溴硅烷的用量可提高反应收率,故选择n(化合物3)∶n(三甲基溴硅烷)为1∶3为该步实验的反应条件.通过单因素考察反应溶剂对化合物4收率的影响,结果表明:以乙腈作为反应溶剂时,化合物4的收率为70.2%,远高于以二甲基甲酰胺和二氯甲烷作溶剂时的收率,二者分别为59.4%和61.2%.究其原因,可能是乙腈和二氯甲烷溶剂中含水分较少,可以减少脱烷基化试剂的水解,从而使反应收率提高,而原料在乙腈中的溶解效果比在二氯甲烷中要好,反应在乙腈溶剂中更易形成均相体系.因此,在后续研究中将采用乙腈作为该步反应的溶剂.2.3 (R)-9-(((2-磷酸单苯酯基)甲氧基)丙基)-腺嘌呤原合成工艺路线采用二环己基碳二亚胺(DCC)作催化剂,(R)-9-[2-(膦酰基甲氧基)丙基]腺嘌呤与苯酚反应制得(R)-9-(((2-磷酸单苯酯基)甲氧基)丙基)-腺嘌呤.其中,苯酚为高毒性试剂,且用DCC做催化剂的催化效率不高,DCC反应后生成的1,3-二环己基脲(DCU)难以除净,需要经过繁琐的后处理步骤.根据预实验结果发现,以另一工业化试剂亚磷酸三苯酯代替高毒性试剂苯酚、高效催化剂DMAP代替DCC进行反应,省去了原合成路线多次过滤,先碱调再酸调pH值的众多繁琐步骤,化合物5的收率由50.7%提高至70.6%.2.4
