What happened to the Elephant Man drug trial?
German drug manufacturer TeGenero went bust after the disastrous first human trial of its supposed wonder cure TGN1412. It emerged the firm had inadequate insurance, for a total of only £2million – leaving the victims in limbo as the company that conducted the trial, Parexel, at first refused to accept joint liability.
What happened in the TGN1412 trial?
It found that preclinical studies performed with TGN1412 failed to consider what constituted a safe dose for use in humans. In addition, it made 22 recommendations for improving the safety for Phase I trials of higher risk medicines.
Why did TGN1412 fail?
It is likely that activation of CD4+ effector memory T-cells by TGN1412 was responsible for the cytokine storm. Lack of CD28 expression on the CD4+ effector memory T-cells of species used for pre-clinical safety testing of TGN1412 offers an explanation for the failure to predict a ‘cytokine storm’ in humans.
Is TGN1412 used today?
Originally intended for the treatment of B cell chronic lymphocytic leukemia (B-CLL) and rheumatoid arthritis, TGN1412 is a humanised monoclonal antibody that not only binds to, but is a strong agonist for, the CD28 receptor of the immune system’s T cells….Theralizumab.

How can clinical trials go wrong?
Projects fail when they do not meet the study’s primary endpoint. Why is it that clinical trials go wrong more often than not? There are many different reasons to explain this, mainly including lack of efficacy, safety concerns, strategic reasons and economics, or some combination of these.
Was the facility a true story?
Turns out, it is based on the TGN1412 drug trial… but the patients there were all administered the drug at the same time, and simply did not have any ability get up, much less try to kill each other. (Well, that would explain why the real patients didn’t escape.) But not this film script.
How was TGN1412 administered?
The mAb was administered by IV infusion (duration of 3 to 6 minutes) to six healthy subjects at a starting dose of 0.1 mg/kg. This dose was reported to be 1/500th of the safe animal dose.
Was TGN1412 tested on animals?
According to TeGenero, the drug has been tested extensively in laboratory animals including rabbits, dogs and monkeys with no drug-related adverse events. However, several studies have pointed out crucial species differences between humans and monkeys in the particular function of the immune system.
What is a mAb drug?
Monoclonal antibodies (MABs) are a type of targeted drug therapy. These drugs recognise and find specific proteins on cancer cells. There are many different MABs to treat cancer.
Why do drug trials fail?
Failures can arise from a lack of efficacy, issues with safety, or a lack of funding to complete a trial, as well as other factors such as failing to maintain good manufacturing protocols, failing to follow FDA guidance, or problems with patient recruitment, enrollment, and retention.
Are clinical trials risky?
Yes, all clinical trials have risks. But any medical test, treatment, or procedure has risks. The risk may be higher in a clinical trial because there are more unknowns. This is especially true of phase I and II clinical trials, where the treatment has been studied in fewer people.
Is the movie the woods a true story?
The Woods is a gripping tale of how a man is on the hunt for his missing sister, flitting between both 1994 – the year of Kamila’s disappearance – and 2019, present day. While the series does leave viewers on edge, The Woods is not based on a true story.
What happened in the Northwick Park trial?
In March 2006 six healthy men, all under the age of 40, signed up as volunteers in a drug trial that was being conducted at a research unit based at Northwick Park Hospital in northwest London. The drug being tested was TGN1412, an anti-inflammatory drug designed to treat conditions such as leukaemia, rheumatoid arthritis and multiple sclerosis.
How did the £2 million drug experiment at Northwick Park work?
The men aged 19 to 34 were each paid £2,000 to be given the drug in a private unit at Northwick Park Hospital in North-West London. They were all hooked up to drips in a ward with two rooms, and then at two-minute intervals nurses injected each man with the experimental fluid. The drug was administered ten times faster than it had been in monkeys.
What happened in the UK drug trial disaster?
UK drug trial disaster – the official report. Health 25 May 2006. The final report into a catastrophic drug safety trial that left six men fighting for their lives in the UK in March 2006 has severely criticised Parexel, the firm that carried out the trial.
What happened to the volunteers in the TGN1412 clinical trial?
Six volunteers offered to help in the testing of a new drug, called TGN1412, to treat leukaemia and also diseases like rheumatoid arthritis. However, within 90 minutes of receiving the experimental drug they were writhing in agony as the drug had caused reactions never seen in a clinical trial before, nor in any of the pre-clinical safety tests.
