Data on Gilead’s remdesivir show NO benefit for coronavirus!

刚刚股市直接跳水,找了半天是这个原因。。。。。

https://www.statnews.com/2020/04/23/data-on-gileads-remdesivir-released-by-accident-show-no-benefit-for-coronavirus-patients/

antiviral medicine remdesivir from Gilead Sciences failed to speed the improvement of patients with Covid-19 or prevent them from dying, according to results from a long-awaited clinical trial conducted in China. Gilead, however, said the data suggest a “potential benefit.”A summary of the study results was inadvertently posted to the website of the World Health Organization and seen by STAT on Thursday, but then removed.

“A draft document was provided by the authors to WHO and inadvertently posted on the website and taken down as soon as the mistake was noticed. The manuscript is undergoing peer review and we are waiting for a final version before WHO comments,” said WHO spokesperson Tarik Jasarevic.

Gilead spokesperson Amy Flood said the company believes “the post included inappropriate characterization of the study.” Because the study was stopped early because it had too few patients, she said, it cannot “enable statistically meaningful conclusions.” However, she said, “trends in the data suggest a potential benefit for remdesivir, particularly among patients treated early in disease.”

The data will be closely scrutinized but are also likely imperfect. The study was terminated prematurely, which could have affected the results. The context that would be provided by a full manuscript is missing, and the data have not been reviewed as normally occurs before publication.

这个药就是很难做临床。给重症用吧,重症是因为细胞因子风暴,不是因为病毒,这个药作用于病毒的,按理说用处不大。给轻症用吧,这个药需要静脉注射,还要监测肝功,得住院,轻症现在都不住院。再说轻症转重症本来就20%不到,得很大样本才能下结论,这些人还不能用其他抗病毒药,本身就难。还有据说这个药对肝功能有要求,本来对正常人不是什么难事,但新冠病毒本身就会导致很多病人肝功能异常,就难了。相比之下,像羟喹啉这种口服的副作用(在试验剂量下)小的药做起临床试验就容易多了。

Jefferies remdesivir Rem-D Mixed data? Probably some benefit but modest Key points: (1) This is disappointing to not show at least positive trends on efficacy or safety, so expectations will come down now for the GILD-sponsored studies coming up (severe patients with no placebo arm due in next week, and moderate patients with a control arm (standard care but no RemD) due by end of May. The one tidbit that isn't positive too is there appeared to be no big viral reduction (stopping the virus) or virologic benefit in drug patients (which is how the drug is supposed to work and would support biological rationale for why it's helping pts scientifically). However, this may not be shocking in severe patients who are too far gone. Either way, expectations were probably far too elevated after a 10-15% move last week on other media reports from University of Chicago. (2) However, the study was halted early and was not well-powered so bulls will say the study is flawed. In addition, GILD has suggested the study not only was never completed by the China govt, but there may be positive trends in "healthier" pts or those who were treated earliest, which makes logical sense and may be good support for the upcoming moderate patients study later in May which is against a placebo. Of note, China also stopped their moderate study too, so both studies in China were stopped early.

千里不留行
这个药应该象tamiflu一样使用,在最初期,应该有效。问题是新冠可怕的是病毒初期大量复制的时候是无症状的。什么时候使用是个难题。 临床也难做。重症以后各种继发感染,免疫风暴都来了,那时候抗病毒可能都不管用了,更紧急的任务是抑制继发感染,减少血栓,纠正休克什么的。
