Tropical Drug Ivermectin Being Tested on Critically ill Patients in Ireland

Irish COVID-19 patients being treated in intensive care are to start receiving the drug ivermectin as part of an international clinical trial. Ivermectin is an anti-parasitic drug that has been controversially promoted by some as a cure for the disease.  The study is part of the international Remap-Cap study covered previously by TrialSite.

Ivermectin as a Treatment Option 

In 2015, Donegal scientist Professor William Campbell shared the Nobel Prize in Physiology or Medicine for his role in the discovery of ivermectin. Launched in the 1980s as a drug against parasites, it was crucial in treating river blindness in many tropical countries. Ivermectin is used in various animal medicines including ones for roundworms, mites and lice in sheep and cows. Interest in ivermectin for Covid-19 was sparked by an Australian study in April last year that showed it killed SARS-CoV-2 in a test tube. 

Some patients in Irish hospitals have now received it as a treatment. Since it is an approved drug, it is at the discretion of clinicians to decide if an individual patient will benefit from it. 

“Its use has crept into practice without a huge amount of evidence to support it,” said Professor Alistair Nichol, intensive care doctor at St Vincent’s University Hospital, Dublin. “There have been some clinical trials, but they haven’t been of the highest quality.” 

International Trial for Efficacy

A new international trial plans to answer, once and for all, if ivermectin is beneficial to Covid-19 patients. Prof. Nichol leads the Irish contribution to the trial, which is expected to start within weeks after it receives approval. 

Having so many patients, from different countries, should help answer definitively if the drug is beneficial. “There has been a huge amount of media interest [in ivermectin],” said Prof Nichol. “There have been campaigns to put it in [treatment] guidelines, even though there is little evidence to support it.” The US Food and Drug Administration does not recommend its use to treat Covid. 

The ivermectin study is part of a larger international trial (Remap-Cap) that involves thousands of patients. This was set up to look at treatments for pneumonia, before Covid, in the expectation that the next pandemic would involve a respiratory virus that would trigger a flood of patients with pneumonia. This trial recently reported that Covid-19 patients benefit from receiving either of two antibody therapies – tocilizumab and sarilumab – which block a compound in our body that promotes inflammation. It also contributed to advice from the World Health Organisation in September last year that steroids could be used to treat severely ill Covid-19 patients. The US’s drug regulator expressed concern last April that people might self- medicate by taking ivermectin products intended for animals, which it said could cause serious harm.

Lead Investigator

Professor Alistair Nichol, intensive care doctor at St Vincent’s University Hospital, Dublin, says, “There have been lots of media stories where people received ivermectin and said it was a miracle cure.” He added, “But there is not a whole load of hard evidence to back up its efficacy, or safety.”

Prof Nichol is approaching ivermectin as a Covid treatment with a dose of scepticism, but he said that the results from a large trial are necessary. “We need to provide an answer for clinicians,” he explained. “Because clinicians are using it, and will continue to use it. We will find out if that is a good idea, or if it is not.”

Trial Site

Five Irish hospitals are likely to participate. Irish patients will receive either a four-day course of ivermectin, or no ivermectin. The outcome of these two groups of patients will then be compared. The same study will be run in France, Pakistan, Nepal, the Netherlands, the US and Canada.

Responses

  1. Here is a large multi-site trial that’s meant to “to answer, once and for all”, if an old inexpensive safe medicine “is beneficial to Covid-19 patients.” And that gives this medicine to CRITICALLY ILL patients, even though the question to be answered is about EARLY treatment. Where have we seen it before? Does hydroxychloroquine ring a bell? That’s how they tanked it, and that’s how they are trying to tank ivermectin.

  2. Ivermectin does work for patients with low oxygen saturation (<90%). Adding ivermectin inhalations (4 ml of 0.5% ivermectin aqueous solution, repetition interval 48 hours) to standard therapy (Clexane, Famotidine, Dexamethasone, D3) for 18 patients allowed 17 patients to avoid resuscitation. Ivermectin inhalation works wonders!

  3. More nonsense about about ivermectin. It has been more than a year since this virus appeared. In March of 2020 the question was does it really work. Through the following 3 -4 months it was proven it does. Main stream media, politicians, WHO, NIH, social media and a few I probably forgot because there is so much bias it is very hard to remember all the outlets that are suppressing and even discrediting viable life saving information it sickens me. If all you want to do is make money from this “wonderful” opportunity, shame on you. In the end the truth will come out and all your profits will disintegrate. I hope you lose it all to the people you deceived.

  4. No hard evidence, unknown safety? What do these people do for a living seriously? I’m no Doctor but all these statements are false…and the “within weeks” you would be forgiven for thinking there is no urgency to this…no progress in weeks on it either since it was first mentioned….very disheartening.. Well done Trial site for keeping an eye on it!
