Subject: NATAP: HCV New Drugs Update Selected Highlights


HCV Update Selected Highlights
from Jules: Currently approved are 2 protease inhibitors telaprevir & boceprevir. In phase 3 now are 4 drugs: 2 proteases TMC435 & BI1335; nucleotide GS7977; and NS5A BMS052. Also in phase 3 is Peg Lambda, a peginterferon that has showed in trials similar efficacy to current Peginterferons with little of the side effect.  Phase 3 for these drugs should be finished in about one year with varying finish timelines between these drugs. Abbott is about to start phase 3 studies, they have 4 drugs in 3 classes: protease, NS5A, NNRTIs. Gilead has drugs in 4 classes: nucleotide, protease, NNRTI, NS5A. BMS has drugs in 4 clases: NS5A, NNRTI, nucleotide (trial just suspended, evaluating), protease; Roche/Genentech has drugs in 3 classes: protease, nuke, NNRTI. Vertex has drugs in 3 classes: protease, nucleotide, NNRTI. Merck has drugs in 2 classes: protease in development in addition to boceprevir, NS5A. Tibotec has protease TMC435 in phase 3 now with other drugs further back in development.

So in about 1 year we will have 2 brand new classes of drugs BMS052 the potent NS5A, GS7977 the potent nucleotide, plus the 2 new proteases currently in phase 3 BI1335 & TMC435. At this time we don't know if patients & clinicians will be able to combine the NS5A+GS7977 or a 3-drug combination of a protease TMC435 + the NS5A BMS052+GS7977. A small phase 2 study at EASl in April of about 40 patients showed SVR rates of 100% using GS7977+BMS5435, but there is not a followup study ongoing with these 2 drugs. There is an ongoing study now in null responders lookimg at TMC435+GS7977, we await these data, expecting good results. For null responders we have some data below in small studies finding that 2 BMS orals, the protease+NS5A + peg/RBV could cure 100% of patients.

Following this chart are links to the key studies recently reported that capture the data for these drugs.

New Drugs, I tried to capture all the key drugs in development & their timelines, dont think I missed anything key

主题:NATAP:丙型肝炎的新药更新选定的重点

丙型肝炎病毒更新选定的亮点

从儒勒:目前批准的2蛋白酶抑制剂telaprevir治疗和boceprevir。在第三阶段,现在是4种药物:2蛋白酶TMC435及BI1335;核苷酸GS7977;和NS5A BMS052。此外,在第三阶段,表明在临床试验中的副作用小,疗效相似,目前Peginterferons聚乙二醇是钉LAMBDA。 3相对于这些药物应在一年左右完成,完成时限,这些药物之间的不同。雅培是启动阶段的3项研究中,他们有3类4种药物:蛋白酶,NS5A的,NNRTIs。基列有4类药物:核苷酸,蛋白酶,具有NNRTI,NS5A的。 BMS的有药物在4 clases中NS5A的,具有NNRTI,核苷酸(审判只是暂停,评估),蛋白酶,罗氏/基因泰克有3类药物:蛋白酶,核弹,具有NNRTI。顶点有3类:蛋白酶的药物,核苷酸,具有NNRTI。默克公司在2类药物:在发展中蛋白酶此外,NS5A的boceprevir。 Tibotec公司有TMC435蛋白酶在第3阶段,现在进一步在发展其他药物。

因此,在1年左右,我们将有2药物BMS052有力的NS5A,GS7977品牌的强有力的核苷酸,加上2个新的新的蛋白酶类目前在第3阶段BI1335与TMC435。在这个时候,我们不知道,如果患者和医生将能够结合的NS5A的GS7977或蛋白酶TMC435的药物组合+ NS5A的BMS052 + GS7977。小第2阶段约40例患者4月EASL研究表明SVR率100%使用GS7977 + BMS5435,但没有这2种药物进行后续研究。 + GS7977 TMC435 lookimg空反应是现在正在进行的研究,我们等待这些数据,预期良好的效果。为空的反应,我们有下面的一些数据,在小的研究发现,2拜耳orals,蛋白酶+ NS5A的PEG /利巴韦林可能治愈患者100%。

这个图表是链接到最近报道,捕获的数据为这些药物的重点研究项目。
