Could you provide a link to one of these clinical trials with large sample sizes that show no benefit? I have seen none of these.Ranger222 said:
"Retrospective analysis" is a red flag.
There have been clinical control trials with large sample sizes and they show no benefit.
Not sure why we want to continue to beat this dead horse. There is no benefit, unless you are trying to manufacture one.

The only two completed clinical studies I'm aware of are both from March, small sample sizes and both showed promise (one from Wuhan, one from France). Beyond that, I'm aware of two ongoing double blind clinical trials, one from NIH, one in Spain, these are scheduled to complete in September. They were both delayed once the retrospective analysis showing HCQ to have no effect was found to be based on invalid and falsified data. NEJM and the Lancet both pulled back their analysis and "expressed concern".

Don't you know? The science is settled.
Every clinical trial I have seen with negative or minimal results have been from treating patients that are already hospitalized or not in combination with Zinc and Z pack. The premise behind the efficacy of the drug is to slow down viral replication. So testing at a late stage in the disease is ineffective by design.
I don't know if HCQ is effective or not. I just haven't seen a clinical trial that tests the drug in the way that doctors who are seeing positive anecdotal results have recommended.

While I agree that I don't think HCQ should be used for or will show any benefit in hospitalized patients. The Recovery Trial results are extremely suspect. They concluded it showed no benefit and possible harm since 25.7% died in the HCQ group and only 23.5% in the usual care group. However, in this study they gave 2400 mg of HCQ on day 1 while doses greater than 1600 mg are considered toxic. In France a dose of over 1875 mg requires immediate admission and hospital care. In addition to the loading dose they continued to give 800 mg per day for 9 days. That is a total of 9600 mg of HCQ.Dr. Not Yet Dr. Ag said:https://www.recoverytrial.net/news/statement-from-the-chief-investigators-of-the-randomised-evaluation-of-covid-19-therapy-recovery-trial-on-hydroxychloroquine-5-june-2020-no-clinical-benefit-from-use-of-hydroxychloroquine-in-hospitalised-patients-with-covid-19kb2001 said:Could you provide a link to one of these clinical trials with large sample sizes that show no benefit?

Pre-print is not out yet, but they have already reported the results and have clearly listed study protocols on their website.The WHO and NIH also stopped their trials and reviewed their data from their ongoing RCTs which both found no benefit.

A higher dose shouldn't necessarily result in less efficacy. The percentages you cite are not clinically significant in their study so "possible harm" is a bit of an overstatement (at least statistically, sorry have had arguments with FDA statisticians regarding p-values interpretation but I'm ultimately biased by my ownership %). Though I agree safety could bias the endpoint (time to mortality) if you're "pushing"(/causing/biasing) mortality with a higher dose. Did the study result in significant toxicity or SAEs b/n the treatment arms (studies usually show Grade 3/4 AEs amongst the arms or report significant SAEs amongst the arms)? (Only looked up their info on their website and haven't seen details.) Also, not sure how they wrote their SAP but they could control/account for AE's caused by the treatment by censoring within the KM curves.Reveille said:While I agree that I don't think HCQ should be used for or will show any benefit in hospitalized patients.

Compare to what we are typically doing in the outpatient setting. Which is 800 mg on day one and than 400 mg for days 2-5. A total of of 2400 mg for the whole treatment. So considering these extreme dosages I am surprised there was not more deaths from arrhythmia's. The Author's have responded saying "There's no recommended dosage for Covid-19 because it's a new disease." While true using a dose 4 times the maximum dose and considered a toxic amount seems very unreasonable.
Its as effective as a tic tac in hospitalized patients. It is an ionophore so it will allow zinc into the cell and zinc stops viral replicase this is a fact. Now does it have any any activity in of itself on COVID? Maybe not but it is possible, but a good ionophere and zinc is a good regimen for many viruses. That said there are over the counter ionophores like quercetin that might do just as much as HCQ for prophylaxes or early stage treatment. The funny thing is those saying it doesn't work are only quoting studies in hospitalized patients, well it wouldn't work there much too late at that point.2PacShakur said:
Is it enough to supply what would be a mass administration of 10's or 100's of thousands of patients? We still seem to have PPE shortages despite ramping supplies of those. Also, who pays for it especially as so far it has been shown as effective as a tic-tac. Look, if a study comes out and shows its niche treatment indication and/or disease stage, then so be it but until then let it play out.

Quote:
A reverse natural experiment happened in Switzerland. On May 27, the Swiss national government banned outpatient use of hydroxychloroquine for COVID-19. Around June 10, COVID-19 deaths increased four-fold and remained elevated. On June 11, the Swiss government revoked the ban, and on June 23 the death rate reverted to what it had been beforehand. People who die from COVID-19 live about three to five weeks from the start of symptoms, which makes the evidence of a causal relation in these experiments strong.

For those who are refused Hydroxychloroquine by their doctor, is Quercetin the next best thing in facilitating zinc transportation?
