BOSTON – The annual American Society of Cell and Gene Therapy (ASGCT) conference got underway in Boston this week with a guest appearance by one of gene therapy’s greatest ambassadors and patient advocates.
Victoria Gray, the sickle cell warrior who was successfully treated in the exa-cel clinical trial sponsored by Vertex Pharmaceuticals/CRISPR Therapeutics seven years ago, spoke in an evening workshop organized by the Emily Whitehead Foundation and ScaleReady.
Boston is becoming a regular stomping ground for Victoria. Last November, she spoke at the Genetic Agency Technology Conference, hosted by Dyno Therapeutics. Last month, she finally received an invitation to visit the headquarters of Vertex and speak in a town hall meeting.
In an extemporaneous 20-minute speech, Victoria talked about her lifelong journey with sickle cell disease (SCD). She recalled her first major pain crisis, when she was a young girl—a lightning-type pain that began in one arm before traveling across her chest and down the other arm. “In minutes, my entire body was engulfed in pain,” she said. “The pain felt like getting struck by lightning and hit by a truck. It took me to the floor.” Her grandmother provided hot towels and Tylenol, but nothing worked—not even prayer. After a week in hospital, Victoria returned home but still felt fatigued.
Stricken by regular pain crises, a hallmark of SCD, Victoria encountered numerous disappointments growing up. Her hematologist said she could not join the cheer team. In eighth grade, she was told she could not join the basketball team, because the exertion would provoke a pain crisis. “As a kid, I was like a Timex: I could take a licking and keep on ticking,” she joked.
In high school, she signed up to join the United States Navy. “I wanted to serve my country,” Victoria recalled. As she was preparing for basic training, she learned that her disease prevented her from enrolling. “So that was another dream lost.” Next, she turned her attention to nursing. Victoria graduated high school in 2003, but it took another seven years before she could qualify for a nursing program. “Professors didn’t understand because I looked whole and complete. They didn’t think I was sick.”
In 2010, just before Halloween, Victoria had the worst pain crisis of her life, stripping her ability to walk or use her arms to feed herself. “I couldn’t do anything, facing some of the worst pain of my life. I was getting strong pain medicines like Dilaudid, ketamine, but still couldn’t move. Pain had taken over my thoughts.” Unable to sleep or even take a nap, Victoria was desperate to go home to her family.
Later, she asked the doctors if they had heard about a haplo-bone marrow transplant (BMT). “I can’t continue living like this,” she said. The doctors looked at each other and said no. After weeks of prayer, Victoria received a call from her hematologist. “Victoria, I have good news, but I only want to tell you in person.” For the first time in her adult life, Victoria was excited about a doctor’s appointment.
She traveled to Nashville with her brother, who would be her BMT donor, and her husband. She met Haydar Frangoul, MD, whom Victoria calls, “the nicest doctor that I’ve met in my adult life.” Frangoul told her: “Victoria, I wish I had met you ten years ago!’
Although Victoria’s brother was a suitable BMT match, Victoria was scared of the possibility of graft vs. host disease (GVHD). “My purple pill basket was filled to the brim with medicine every day. If I would acquire [GVHD], that basket would have to triple in size.”
“I’m a human!”
On her next visit to Nashville, she had to extend her stay because of another pain crisis. But that stay changed her life. Frangoul sat next to her bedside. “Victoria, have you ever heard of CRISPR?” he asked. Victoria shook her head.
Frangoul used a typo-in-a-textbook analogy and reassured Victoria that there was no chance of GVHD, because she would be receiving her own modified stem cells. “You’ll be the first person to do this, Victoria,” he said. “First human?” she asked. “Yes,” Frangoul said, “but it’s been tested in primates.”
“But I’m a human!” she said.
After being reassured that she could still try a bone marrow transplant if the procedure did not work, Victoria agreed to move forward. The chemotherapy, was “hell on Earth,” she recalled. “I lost my hair, which I was prepared for, but the mucositis, the sores in my mouth, the inability to eat for two weeks, was gruesome.”
Victoria swallowed her tears and decided to fight. This was the first time she had been in the hospital by her choice, to live for her children. About eight months after receiving her CRISPR-edited stem cells in July 2019, she woke up one morning, not feeling anything. “Oh my God, I’m dead,” she thought. She called her kids into the room and hugged them, slowly realizing that “this is what normal feels like.” For the first time in more than 25 years, Victoria did not have any pain in her lower back and hips. She was able to breathe deeply without wincing.
A few years after her therapy, Victoria was finally able to take her first ever flight, to Washington D.C. to visit her husband, who was on deployment. “It was the first time that I was ever able to show up for the man who has shown up for me,” she said. She has since watched her daughter dance in a Christmas parade and supported her son playing high school football. “The little things have brought me great joy,” she said.
Her second flight was a business class trip to London with her husband in March 2023, where she spoke at the third International Summit on Human Genome Editing. “I got to keep my covenant that I made with God, that God, if you do this for me, I would tell the world about what you did.”
Victoria welcomed her first granddaughter on Christmas Eve, 2024. Next week, another milestone: she will be in the audience as her twins graduate high school. And next month, she will publish a children’s book called Hema’s Journey, the tale of her inspiring journey with CRISPR gene therapy. She’s currently training for a group effort to climb Mt. Kilimanjaro.
Perhaps at next year’s ASGCT conference in Philadelphia, she will be invited to present in a plenary session on the main stage. It would be hard to think of a more fitting speaker.
