At least, that's what Dr. James Olson might say. Dr. Olson is Seattle's premier pediatric hemato-oncologist – a field of medicine that treats childhood cancer and blood disorders. As the story goes, while studying at the University of Michigan, a professor asked Olson what he wanted to do with his life. Olson replied, "I want to deliver light to cancer." To which the professor chuckled, "Okay, Buck Rogers… what is it that you really want to do?" Ever since, Olson has been on a mission. And after 25 years of painstaking cancer research, he's hit on a stunning breakthrough… Any doctor will tell you that breaking terrible news to a patient is one of the most gut-wrenching conversations you can have. Olson has certainly experienced his share over the course of his career. One instance came after performing a 12-hour surgery on a young child's brain. They’re known as “iatrogenic injuries,” and they happen for two reasons: either by accident, or because of technological restraints. The boy had a cancerous tumor that was so severe, it became almost impossible to differentiate the healthy brain matter from the cancerous matter. With surgeries of this magnitude, even a man as experienced as Dr. Olson can encounter complications. It meant that not only was he unable to remove the entire tumor, he also couldn't help taking out some non-cancerous matter with the portion he did remove. Sadly, it left the boy with brain damage. With an organ as complex as the brain, this is sometimes an unavoidable outcome for some patients. They're known as "iatrogenic injuries," and they happen for two reasons: either by accident, or because of technological restraints. In Olson's case, it was the latter. And after the traumatic operation, he knew he needed to address such complications. So he decided to pursue his dream of "delivering light to cancer." And you won't believe what's helped him figure it out… After several years of trial and error, Olson and his team at privately owned Seattle biotech firm, Blaze Bioscience, have created something called "tumor paint." And the solution has come from the most unlikely of places… Scorpion venom. As Olson states, "Scorpions have been evolving for millions of years. For survival, they need to make a drug that can get into the brain and paralyze their prey. The Israeli death stalker scorpion makes these little tough mini proteins, and it turns out that this one happens to bind to cancer cells, but not to normal tissues." The protein that Olson is describing is called chlorotoxin. It's a major component of the venom injected from the sting of a scorpion's tail. Once it's infused into the bloodstream, the venom naturally travels to the brain and attaches itself to chloride channels that lay on the surface of cells. And as it turns out, chlorotoxin actually prefers the chloride channels on tumor cells above all other tissues. Upon realizing this fascinating discovery, the Blaze Bioscience team re-engineered chlorotoxin. They tagged it with molecules that literally act like a flashlight for doctors. It's a fluorescent dye that illuminates the outline of the tumor in its entirety, making it easier for brain surgeons to operate without error – and remove all of the cancer. All a surgeon needs to do is inject their patient with the tumor paint formula. The scorpion venom naturally seeks out the brain tumor cells, and the molecular flashlight makes the tumor glow with a brilliant light. The surgeon can see the outline of the tumor in relation to the non-cancerous brain matter, and perform accordingly. Tumor Paint There's another important aspect here, too. This scorpion venom process happens in real-time. Contrast that with current methods like an MRI scan, for example, where surgeons can only see if they've fully removed a tumor after a patient has been stitched back up. Needless to say, that costs more time, more money, and the potential for more invasive surgery or chemotherapy if a portion of the tumor remains intact. But with tumor paint, a surgeon can see immediately if he's got the whole tumor before the end of the operation. Blaze Bioscience calls its scorpion venom treatment BLZ-100 – and the company's research is so revolutionary, it just scooped up a cool $8 million in Series-B financing from angel investors, in order to conduct further trials. In fact, since the company's inception, it's had little trouble attracting financial backing. With tumor paint, a surgeon can see immediately if he’s got the whole tumor before the end of the operation. That's due in no small part to acting CEO, Heather Franklin – the executive who led ZymoGenetics before Bristol-Myers Squibb bought the company back in 2010. She's already leading the tumor paint discovery from mice trials into human testing, as well as overseeing efforts to re-engineer tumor paint for use against other cancers – including prostate, colon, breast and ovarian. The funding that Blaze is receiving has also allowed the company to recruit the added expertise of several doctors and pharmaceutical engineers, as it tries to advance BLZ-100 from the lab to every clinic in America. We're talking about people like Dr. Dennis Miller and Dr. Claudia Jochheim, both of whom have excellent track records in bringing new drug candidates to market. Their resumes include ZymoGenetics, Amgen, Corixa and Immunex, to name a few. Venture capitalists, take note. And investors, too. Although Blaze is privately owned at the moment, as the profile rises on BLZ-100′s remarkable treatment, continued progress could see a bigger biotech firm join forces with the company – or even buy it outright. This is, without question, a story that I'll be keeping a close eye on. And naturally, I'll bring you any updates as soon as they happen.

Alas too late to save my co-worker who passed 4 years ago. Good man, kids, exactly the wrong age to get cancer (~50). First sign was odd conversation. Definitive sign was a seizure and car accident. Had surgery, a chemo chip put in his brain, lived another 18 months. Was able to continue working, at a reduced rate, except for the last month. "If an angry bigot assumes this bountiful cause of Abolition, and comes to me with his last news from Barbados, why should I not say to him, 'Go love thy infant; love thy wood-chopper: be good-natured and modest; have that grace; and never varnish your hard, uncharitable ambition with this incredible tenderness for black folk a thousand miles off. Thy love afar is spite at home.'" |
