Kymriah’s Journey From Lab to Lifesaver: The Phase 1 Trial [Part One]

Kymriah. For kids with high-risk leukemia, those seven letters spell hope. But what is this lifesaving ‘living drug’? And how did this exciting new therapy come to be? Buckle your seat belts, because today we are starting an epic journey – a journey made possible by St. Baldrick’s supporters like you. Over four blogs, we’ll follow the path of this immunotherapy breakthrough – from the Phase 1 clinical trial to its recent FDA approval — and see the process through the eyes of the kids, families and St. Baldrick’s researchers who made this revolutionary research happen.


In Part One of our blog series, meet St. Baldrick’s Honored Kid Austin, a now 9-year-old cancer survivor whose last chance at life was the first human trial for Kymriah.

Austin wears a face mask

Honored Kid Austin was diagnosed with a high-risk form of acute lymphoblastic leukemia when he was 2 years old.

Kim Schuetz can’t forget the moment she saw the symptoms of her son’s childhood cancer. It was May 2011 and Austin was nearing his third birthday. Austin and his grandpa were playing together when the man noticed something odd. He called Kim over and together they crouched by the living room couch to look at large bumps on the sides of Austin’s neck.

“That’s when my stomach dropped,” she said. “They’ve got one of those portable dishwashers and we sat him on top of the dishwasher. We looked at him from behind to see the difference and how jutted out the lymph nodes were.”

On the left side, it looked like two golf balls were wedged under the tot’s skin. The lumps on the right side were slightly smaller, but no less alarming. Kim, who’s an experienced adult oncology nurse, examined her son. She ran her hands across the large knots and down his clavicle, feeling pea-sized bumps under her fingers.

Austin had been sleeping normally and eating well.  (In fact, before his diagnosis, Austin enjoyed a steak dinner. “I’m not kidding you, he probably put down a good-sized ribeye, for a 2-year-old,” Kim recalled.) He looked healthy and acted healthy, but deep down Kim knew something wasn’t right.

After days of antibiotics, they went to the emergency room. Austin’s blood tests came back normal and Kim took that as a hopeful sign.

But further tests were not as hopeful. As Austin frolicked in the hospital’s playroom, the doctors gave his family the news. They suspected Austin had leukemia. It was later confirmed as high-risk B-cell acute lymphoblastic leukemia (ALL).

“I felt like I was floating up above me and watching somebody else’s life,” Kim remembered. “Your brain goes numb and it’s hard for you to think.”

Austin and his family share a moment in his hospital room

Honored Kid Austin with his mom, Kim, who’s an oncology nurse, and his dad, Jeff. They explained childhood cancer to Austin in words he could understand and called it ‘cooties.’

More than most, Kim knew the tough journey ahead of them. For her, the ambulance ride to their local children’s hospital was the beginning of a nightmare. For her son, riding with the paramedics was a blast. It was the best birthday present he could imagine. He was pumped.

That’s the attitude and energy Austin carried through years of tough treatment, a devastating relapse and then a risky bone marrow transplant. He always just wanted to be a kid.

“When there were long chemo days and he would get cranial radiation – and he would be sedated for all of this – my husband and I would just come home ready to collapse at two o’clock, three o’clock in the afternoon and he wants to go outside and jump on his trampoline and play on his play set,” she said. “He just went on and lived life.”

The Phase 1 Clinical Trial

The bone marrow transplant was supposed to be the end. It was Austin’s last, best option for a cure. But two months after transplant, in May 2013, Austin’s dad came home from work early. Jeff walked down the stairs to where Austin and Kim were playing. Tears brimmed in his eyes. It was the first time Austin had seen his dad cry.

A routine biopsy showed that the 4-year-old’s cancer was coming back. Their oncologist drove to the Schuetz house that Saturday and sat with them as they quietly digested the news. There was no clear-cut way out of this. The boy’s options for survival were slim and shaky at best.

But Dr. Christian Capitini, a member of the St. Baldrick’s – Stand Up To Cancer Pediatric Cancer Dream Team and Austin’s transplant doctor, had an idea.

It was a St. Baldrick’s-supported Phase 1 clinical trial for a ‘living drug’ called Kymriah.

“He [Austin] had already had a bone marrow transplant. He already had several different chemotherapy regimens and nothing was able to really control his disease,” Dr. Capitini said. “To try something like this, which at the time we had no idea how successful it could be, was high risk, high reward.”

Kymriah is called a ‘living drug’ because scientists genetically modify a patient’s own immune cells in the lab, then infuse these new cells back into the patient’s body. These modified cells – called CAR T cells or chimeric antigen receptor T cells – then prompt the child’s own immune system to attack and kill leukemia cells. For that reason, this type of therapy is called immunotherapy.

The patients on Phase 1 trials are often the sickest of the sick, Dr. Capitini said, and the trial may be their last hope for survival.

That was the case with Austin.

“We were told that if we didn’t have this, that there was no other option, that Austin had maybe three to six months to live,” Kim said. “We had to go for it.”
