2011年5月23日,美国食品药品监督管理局批准Incivek(telaprevir)用于成人慢性肝炎的治疗,该药物可用于未接受过干扰素类药物治疗或对之前的药物治疗无效的患者,FDA批准Incivek与干扰素(聚乙二醇干扰素&alPH;联用病毒唑)联用治疗丙肝。
目前慢性丙肝的标准治疗方法是聚乙二醇干扰素&alPH和病毒唑联合使用48周,该疗法只对不到50%的受试患者有效。
通过对2250名成年患者及三项临床三期试验对Incivek的安全性及有效性进行评估,受试者有未接受过丙肝治疗的患者也有已经接受过相关治疗的患者,所有受试者均同时接受标准丙肝治疗。未接受过丙肝治疗的患者使用Incivek有79%的持续病毒反应(治疗停止后24周,受试者血液中未检出丙型肝炎病毒)。在所有的受试患者中,服用Incivek的受试者出现持续病毒反应的概率要比接受标准治疗高20~45%左右。
临床研究显示,大多数受试者使用Incivek的时间可由48周缩短到24周左右。60%未接受过丙肝治疗的受试者有仅治疗24周(标准治疗组为48周)就达到了早期反应。这些受试者持续病毒学反应约为90%。治疗结束后如仍持续病毒反应,则表示丙肝已经治愈。
持续病毒反应可以降低肝硬化及相关并发症的发生,降低肝癌(肝细胞癌症)及死亡的发生率。
FDA药物评价与研究中心,抗菌药办公室的负责人EdwardCox博士表示:Incivek获批,有两种治疗丙肝的重要选择,为治愈丙肝这种严重疾病提供了更多的治疗机会,可增加治愈概率,减少治疗时间,是治疗丙肝的重要进步。
根据美国疾病控制预防中心的数据显示,美国约有320万患有慢性丙肝的患者,该肝炎会影响患者肝功能并可能引起肝衰竭。大部分的肝炎患者在肝损伤发生之前都没有明显的症状,而这一潜伏期可能持续数年。
美国进行肝脏移植到患者主要是因为丙肝病毒感染并潜伏发展,在感染乙肝病毒后(HCV),大部分人会患慢性丙肝,继而发展为肝硬化,引发肝脏出血、黄疸、肝腹水、甚至肝癌等。
患者感染丙肝病毒的途径很多:输血、母婴传播、共用注射器、性传播、共用个人用品如剃须刀、牙刷,以及纹身或穿洞工具等。
Incivek为药丸,每日三次佐餐服用,前12周需与聚乙二醇干扰素&alPH和病毒唑联合使用,一般24周即可产生早期病毒反应,而标准治疗需要48周。该药物为蛋白酶抑制剂,可防止病毒的复制。
Incivek与与聚乙二醇干扰素α和病毒唑联用时最常见的副作用有:皮疹、疲劳、红血球数目减少(贫血)、恶心、头疼、腹泻、瘙痒、肛门或直肠刺激疼痛等。如出现严重皮疹,应立即停药。
Incivek有位于麻省剑桥市的VertexPharmaceuticals公司生产上市

INCIVEK™ (telaprevir) is a prescription medicine used with the medicines peginterferon alfa and ribavirin to treat chronic (lasting a long time) hepatitis C genotype 1 infection in adults with stable liver problems, who have not been treated before or who have failed previous treatment.
It is not known if INCIVEK is safe and effective in children under 18 years of age.
IMPORTANT SAFETY INFORMATION
Who should not take INCIVEK
Do not take INCIVEK if you are pregnant or may become pregnant, or if you are a man with a sexual partner who is pregnant.
Do not take INCIVEK if you are taking certain medicines as there could be serious side effects. If these drugs are taken together, this can cause you to have too much or not enough INCIVEK or your other medicines in your body. It can also cause side effects that can be serious or life-threatening. These medicines include: alfuzosin hydrochloride (Uroxatral®), atorvastatin (Lipitor®, Caduet®), ergot containing medicines such as methylergonovine (Methergine®), lovastatin (Advicor®, Altoprev®, Mevacor®), pimozide (Orap®), rifampin (Rifadin®, Rifamate®, Rifater®), sildenafil citrate (Revatio®) or tadalafil (Adcirca®) for the lung problem pulmonary artery hypertension (PAH), simvastatin (Zocor®, Vytorin®, Simcor®), St. John's wort (Hypericum perforatum), or triazolam (Halcion®).
Talk to your healthcare provider before taking INCIVEK if any of the above applies to you. Your healthcare provider may need to change the amount of medicines you take.
Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. INCIVEK and other medicines can affect each other.
Serious Side Effects
INCIVEK can cause serious side effects, including:
•Birth defects or death of an unborn baby
INCIVEK combined with peginterferon alfa and ribavirin may cause birth defects or death of your unborn baby. If you or your sexual partner is pregnant or plan to become pregnant, do not take these medicines. You or your partner should not become pregnant while taking INCIVEK with peginterferon alfa and ribavirin and for 6 months after treatment is over.
You must have a negative pregnancy test before starting treatment, every month during treatment, and for 6 months after your treatment ends. You must use 2 effective methods of birth control during treatment and for 6 months after all treatment has ended. These 2 forms of birth control should not contain hormones, as these may not work as well during treatment with INCIVEK. Talk to your healthcare provider about the forms of birth control you should use during this time.
Two weeks after stopping INCIVEK, you can use a hormonal form of birth control as one of your two forms of birth control.
If you or your partner becomes pregnant during treatment or within 6 months after stopping these medicines, tell your healthcare provider right away. Contact the Ribavirin Pregnancy Registry right away by calling 1-800-593-2214. The Registry collects information about what happens to mothers and their babies if the mother takes ribavirin while pregnant.
•Skin reactions: Mild skin rashes are common with INCIVEK combination treatment. Sometimes these skin rashes and other skin reactions can become severe and require treatment in a hospital. Call your healthcare provider right away if you develop any skin changes with these symptoms: rash with or without itching, blisters or skin lesions, mouth sores or ulcers, red or inflamed eyes like "pink eye" (conjunctivitis), swelling of your face, or fever.
Your healthcare provider will decide if these changes may be a sign of a serious skin reaction. Your healthcare provider will also decide if you need treatment for your rash or to stop INCIVEK or your other medicines. Never stop taking INCIVEK combination treatment without talking to your healthcare provider first.
•Do not take INCIVEK alone to treat chronic hepatitis C infection. It must be used with peginterferon alfa and ribavirin to treat chronic hepatitis C infection.
•Low red blood cell count (anemia) that can be severe. Tell your healthcare provider if you have any of these symptoms of anemia: dizziness, shortness of breath, tiredness, or weakness.
Your healthcare provider will do blood tests regularly to check your red blood cell count during treatment. If your anemia is severe your healthcare provider may tell you to stop taking INCIVEK. If this happens, do not start taking it again.
What should I tell my healthcare provider before taking INCIVEK?
Tell your healthcare provider if you:
•have certain blood problems such as anemia
•have liver problems other than hepatitis C infection
•have hepatitis B, HIV infection, or any problems with your immune system
•have a history of gout or high uric acid levels in your blood
•have had an organ transplant
•plan to have surgery
•have any other medical condition
•are breastfeeding
How should I take INCIVEK?
Take INCIVEK exactly as your healthcare provider tells you. Take two INCIVEK pills 3 times a day, 7 to 9 hours apart, with food. Eat a meal or snack containing about 20 grams of fat within 30 minutes before you take each dose. Talk to your healthcare provider about examples of food you can eat.
If you miss a dose within 4 hours of when you usually take it, take your dose with food as soon as possible. If you miss a dose and it is more than 4 hours after the time you usually take it, skip that dose only and take the next dose at your normal time. Do not stop taking INCIVEK unless your healthcare provider tells you to. If your healthcare provider tells you to stop, you should not start taking it again, even if the reason for stopping goes away. If you take too much INCIVEK, call your healthcare provider or local Poison Control Center, or go to the nearest emergency room right away.
Common Side Effects of INCIVEK Combination Treatment
The most common side effects include itching, nausea, diarrhea, vomiting, anal or rectal problems (including hemorrhoids, discomfort or burning around or near the anus, itching around or near the anus), taste changes, and tiredness. Tell your healthcare provider about any side effect that bothers you or doesn’t go away.
These are not all the possible side effects of INCIVEK. For more information, ask your healthcare provider or pharmacist.
