For $8,000, This Startup Will Fill Your Veins With The Blood of Young People

With no proven benefits.

To Jesse Karmazin, blood is a drug. His startup, a Monterey, California-based company called Ambrosia, is currently enrolling people in the first US clinical trial designed to find out what happens when the veins of adults are filled with the blood of young people.

 

In many ways, he’s right about blood’s life-saving qualities.

A simple blood transfusion, which involves hooking up an IV and pumping the plasma of a healthy person into the veins of someone who’s undergone surgery or been in a car crash, is one of the safest life-saving procedures we have.

Every year in the United States, nurses perform about 14.6 million of them, which means about 40,000 blood transfusions happen on any given day.

But Karmazin, who has an MD but is not licensed to practice medicine, wants to take the idea of blood as a drug to a very different level. He wants to use transfusions to fight ageing.

As a medical student at Stanford and an intern at the National Institute on Ageing, Karmazin explained over a recent phone call, he watched dozens of the procedures be performed safely.

"Some patients got young blood and others got older blood and I was able to do some statistics on it, and the results looked really awesome," Karmazin told Business Insider.

"And I thought, this is the kind of therapy that I’d want to be available to me."

 

So far, though, no one knows yet if blood transfusions can be reliably linked with a single health benefit in people. And researchers doubt Karmazin’s trial will come away with sufficient evidence to point us in that direction.

"There’s just no clinical evidence [that the treatment will be beneficial], and you’re basically abusing people’s trust and the public excitement around this," Stanford University neuroscientist Tony Wyss-Coray, who led a 2014 study of young plasma in mice, recently told Science magazine.

For starters, to participate in the trial, you have to pay. And it isn’t cheap. The procedure, which involves getting 1.5 litres of plasma from a donor between the ages of 16 and 25 over the course of two days, costs US$8,000.

According to the description registered on ClinicalTrials.gov, Karmazin hopes to enrol 600 people in his trial, which he is conducting with physician David Wright, who owns a private intravenous-therapy centre in Monterey.

Before and after the infusion, participants’ blood will be tested for 'biomarkers', a variety of measurable biological substances and processes which are thought to provide a snapshot into health and disease.

So far, Karmazin says he has done the procedure on 30 people. He claims many of them are already seeing benefits, from renewed focus to improved appearance and muscle tone.

But it’s far too early to say if any of these claims are real. For one thing, when all the data is pooled and tested, it could end up being statistically insignificant.

For another, the alleged benefits could amount to a simple placebo effect, i.e. simply coming into a fancy lab in Monterey and paying money to enrol in the study could have made patients feel better.

Whether or not the blood itself had any impact on patient’s health is still up in the air.

Nevertheless, Karmazin, who was initially inspired by studies on mice, remains enthusiastically hopeful.

"I’m really happy with the results we’re seeing," he said.

Studies in mice don’t necessarily translate into results in people

Karmazin’s leading motivation was a series of mouse studies that involve parabiosis, a 150-year-old surgical technique that connects the veins of two living animals. (The word comes from the Greek root word para, or "beside", and bio, or "life.")

One such study, co-authored in 2014 by Wyss-Coray, the same Stanford University researcher who recently questioned the validity of Karmazin’s current trial in people, suggested that parabiosis could rejuvenate a part of the mouse brain where memories are made and stored.

"I think it is rejuvenation," Wyss-Coray told Nature in 2015.

"We are restarting the ageing clock."

In September 2015, his clinical trial in humans in California became the first to start testing the benefits of young plasma in 18 people with Alzheimer’s disease, but those results have not yet been released.

Some of the funding for that small trial came from a company that Wyss-Coray started, called Alkahest.

Other researchers on Wyss-Coray’s team were much more hesitant to come to such conclusions.

"We’re not de-ageing animals," Amy Wagers, a stem-cell researcher at Harvard University told Nature in 2014. Instead of turning old tissues into young ones, Wagers said they were simply helping repair damage.

"We’re restoring function to tissues."
