Researchers Share Key Learnings From T-Cell Immunotherapy Trials

Harper Beare was diagnosed with acute lymphoblastic leukemia when she was just 10 months old. After she wasn’t able to achieve remission through conventional treatment, she traveled to Seattle Children’s to participate in the PLAT-05 T-cell immunotherapy trial. Soon after, Harper was in remission.

Seattle Children’s doctors and researchers continue to believe chimeric antigen receptor (CAR) T-cell immunotherapy has the power to revolutionize pediatric cancer care. Over the past year, they have made tremendous progress with the promising therapy, which has given patients like Harper Beare, Erin Cross and Milton Wright a second chance at life.

Seattle Children’s recently enrolled its 200th immunotherapy patient, and now has nine T-cell therapy trials targeting childhood cancers from leukemia to solid tumors, which is one of the most robust pipelines in the country.

Seattle Children’s researchers are continuously discovering new best practices based on their experience in the trials, and as a result, will share six abstracts this weekend at the American Society of Hematology (ASH) Annual Meeting in San Diego.

“It’s amazing to be at a place in our research where we’re learning from our existing trials, and immediately incorporating that vital intel into our new trials,” said Dr. Rebecca Gardner, oncologist at Seattle Children’s and principal investigator for the PLAT-02 and PLAT-05 CAR T-cell immunotherapy trials. “We are also pleased to now offer several new trials to patients who would otherwise be out of treatment options. Our goal is to offer the best therapy possible, and to never let any patient reach the end of the line.”

Two Years Cancer-Free, Erin Advocates for T-Cell Immunotherapy

At age 2, Erin Cross was diagnosed with acute lymphoblastic leukemia. She achieved remission through her initial cancer treatments, but relapsed in 2016. Out of treatment options, her family found hope in Seattle Children’s PLAT-02 T-cell immunotherapy clinical trial. Erin, now 8, just celebrated her two-year anniversary of being cancer-free.

Each morning, 8-year-old Erin Cross springs out of bed excited to go to school. A third grader in Chester, England, she loves science and math, and imagines a future as a researcher making “potions” in a lab. She loves cracking jokes, rugby and playing make-believe games with her friends on the playground. For Erin, who spent most of her life in the hospital and away from others her age, she cherishes each day she is able to just be a kid.

“It’s amazing to see Erin back to living a normal life,” said her mother, Sarah Cross. “We’re so thankful that we’re able to enjoy time as a family doing regular things like taking picnics, playing on the beach or going to the zoo. It’s time that we never take for granted.”

Nearly three years ago, Cross faced the devastating reality that she may never see her daughter grow up. At age 2, Erin was diagnosed with acute lymphoblastic leukemia (ALL). She was able to achieve remission through her initial cancer treatments, but in 2016, her family received the shattering news that she had relapsed and was out of treatment options.

That was, until they found hope in Seattle Children’s Pediatric Leukemia Adoptive Therapy (PLAT-02) chimeric antigen receptor (CAR) T-cell immunotherapy clinical trial for children and young adults with relapsed or refractory ALL who are not likely to survive with current treatments. In July 2016, Erin’s family arrived in Seattle for the trial.

“Seattle Children’s threw us a lifeline,” said Cross. “We knew we had to get her there. We moved mountains to save our daughter’s life.”

Seattle Children’s Brings Cancer Immunotherapy to a Global Stage

Avery Berg, 13, was diagnosed with a rare brain tumor at the age of 10. She endured six weeks of radiation, five brain surgeries, and six months of high-dose chemotherapy. Avery has been cancer-free for more than a year, but her mom Kristie says that cancer immunotherapy offers hope that other children can become cancer-free without having to endure such harsh therapies.

T-cell immunotherapy continues to take center stage as one of the most promising new cancer therapies of our time. What once sounded like a dream – reprogramming a person’s own immune system to fight cancer – is remarkably becoming a reality. What’s more; doctors and researchers in our own backyard are leading the way in developing this therapy for children and young adults around the world.

From covering the opening of the first T-cell immunotherapy trial when I was an anchor at KING 5 TV, to now seeing this therapy being tested in seven open clinical trials at Seattle Children’s and applied to a variety of cancers, I’ve been amazed to watch the enormous strides researchers have made in the field over a few short years.

The results also speak for themselves – 93% of patients with relapsed or refractory acute lymphoblastic leukemia in Seattle Children’s phase 1 PLAT-02 trial achieved complete initial remission. About 50% were still in remission one year after therapy. Some patients, who were otherwise unlikely to survive with traditional therapies, are still in remission nearly five years after receiving the experimental treatment. This is encouraging news, especially since leukemias are the most common childhood cancers.

And on Oct. 12, I will witness yet another major milestone – Seattle Children’s will bring their groundbreaking therapies to a global stage. Read full post »

Miguel’s Journey to Take Back the Wheel After Cancer Diagnosis

Miguel Navarro, 18, was blindsided by a cancer diagnosis. Today, he’s on the road to recovery.

A single blow to 18-year-old Miguel Navarro’s shoulder turned his world upside down. He was boxing with his friends one afternoon when he felt a snap. He took a hit to his shoulder and immediately knew something was wrong.

“That punch altered my world,” said Miguel.

Miguel went to the emergency room where he found out he fractured his humerus, the long bone in the upper arm. Unfortunately, that wasn’t where his medical journey ended. While undergoing imaging, doctors noticed something amiss, and so Miguel underwent a myriad of tests. At the time, doctors thought what they saw in his imaging results could be a benign tumor.

On Dec. 12, 2017, Miguel was told the tumor wasn’t benign. He had osteosarcoma, an aggressive type of bone cancer. Read full post »

Fighting for Their Lives: Seattle Children’s Immunotherapy Journey

At Seattle Children’s, many children and young adults with cancer are finding hope in T-cell immunotherapy – an experimental treatment that boosts a patient’s immune system and uses it to fight a disease.

Seattle Children’s researchers are leading clinical trials in which a patient’s T cells are reprogrammed to express a chimeric antigen receptor (CAR) on the surface of the cell. The CAR is like a puzzle piece that’s designed to attach perfectly to a specific antigen or marker on the surface of the cancer cell. When they attach, the CAR T cells attack the cancer cells as if they were fighting an infection.

In just five years, Seattle Children’s cancer immunotherapy program has grown tremendously to include trials that target leukemia, brain and spinal cord tumors and solid tumors. Curious how these clinical trials work? Read on to learn more about the immunotherapy clinical trial process at Seattle Children’s.

Harper Beare is ‘Doing Something Amazing’

Harper was diagnosed with acute lymphoblastic leukemia when she was just 10 months old.

When asked about the birth of her daughter Harper, Sydney Beare lights up.

“Harper was 8 pounds, 1 ounce, 21.5 inches and the most beautiful baby I’ve ever seen!” she said.

By all accounts, Harper was an exceptionally happy, and seemingly healthy, baby. She began sleeping though the night when she was just a few days old and almost never fussed, even when teething. Beare said her daughter was “totally content.”

But in July 2017, when Harper was 9 months old, she became seriously ill.

Harper first developed an ear infection, a staph infection and had an infected cut on her finger. During the next month she became lethargic and pale.

Beare noticed bruises on her legs, and later on her back and face. Harper began having diarrhea and vomiting. She also slept all the time. Despite all this, Harper’s well-child checkup in August revealed no concerns.

Then, on Aug. 21, Harper woke up with a fever.

“She was just lying there, with dry, cracked lips, screaming,” Beare remembered, choking back tears. “I was worried something was wrong but I pushed that idea aside because I didn’t want to think anything bad could happen to my baby.”

Bretton Refuses to Let Cancer Keep Him Off the Ice

Bretton Chitwood, 18, is an avid hockey player. He was diagnosed with osteosarcoma in 2016, but has since returned to the ice. He now plays with a custom prosthesis.

On May 18, 2016, Kara Chitwood and her son Bretton Chitwood traveled from their home in Lynden, Washington, to Seattle Children’s for what they thought would be a routine outpatient appointment to get magnetic resonance imaging (MRI) on Bretton’s ankle. Instead, they didn’t end up leaving the hospital. That day would become one they would never forget.

The pain Bretton was experiencing in his ankle was more insidious than they could have ever imagined. Doctors found a mass and said they needed to do a biopsy to determine what it was. One possibility was the unthinkable: cancer. Read full post »

Seattle Children’s doctors and researchers are leading efforts to better treat cancer in children, adolescents and young adults by boosting the immune system with T-cell immunotherapy. Patients who cannot be cured with standard therapies are benefiting from clinical trials developed at the Ben Towne Center for Childhood Cancer Research, and supported by the Strong Against Cancer initiative. 

One of these patients is Aaron. When he feared he might be out of treatment options, Aaron found hope at Seattle Children’s. Now, he shares his story.

Cancer is such an ugly word. On the internet, it has become normal for people to use it to describe things, ideas or people they don’t like. But for me, that word only brings back painful memories of fighting a disease I would not wish on my worst enemies.

I was first diagnosed with acute lymphoblastic leukemia in January 2013. I was 19 years old, living in Vancouver, Canada, and studying computer science at Simon Fraser University.

I became suddenly ill while on a cruise vacation with my family. I had a fever that wouldn’t go away; nausea for no reason; and extreme fatigue. I needed to sleep all the time. I could barely walk. Climbing a flight of stairs felt like trying to climb Mount Everest.

We knew something was very wrong, so my family took me to the Emergency Department at Vancouver General Hospital.

I still remember lying on the hospital bed after the doctor delivered the bad news — I had leukemia. I couldn’t believe it. I asked the nurse as he was putting in my IV, “How long do you think it’ll take before I get better?”

He replied, “My friend, I’m afraid this is just the beginning of a long and difficult journey for you.”
