A 16-year-old girl has been discharged from a hospital in Guangzhou, Guangdong province, after successfully undergoing groundbreaking gene therapy treatment for thalassemia, a hereditary blood disorder.
The patient, identified by the pseudonym Xiao Lin, had been receiving revolutionary RM001 cell treatment at Sun Yat-sen Memorial Hospital of Sun Yat-sen University since June.
After a critical 28-day period of observation and recovery, Xiao Lin has now transitioned to the rehabilitation phase of her treatment, with the prospect of discontinuing medication.
Her treatment offers renewed optimism for patients suffering from severe thalassemia. The genetic condition is prevalent in Guangdong, Hainan, Hunan, Sichuan, Guizhou and Yunnan provinces, and the Guangxi Zhuang autonomous region.
The innovative treatment was sanctioned by the National Medical Products Administration in November last year.
Traditionally, patients with thalassemia rely on allogeneic hematopoietic stem cell transplantation, a method with limited success due to donor matching challenges.
Professor Fang Jianpei from Sun Yat-sen Memorial Hospital, said the groundbreaking gene therapy involved autologous hematopoietic stem cell transplantation and represented a turning point in the treatment of thalassemia.
The RM001 cell therapy is trans-formative as it aims to correct the genetic anomaly causing thalassemia, Fang said. Previously, patients were forced to undergo frequent blood transfusions and take iron-reducing medication to manage the disease's complications.
These complications, known as "iron overload", often led to further health issues, including problems with the patient's appearance, bone density, and endocrine system.
Xiao Lin, who is proficient in activities such as piano, chess, calligraphy, and painting, in addition to excelling at school and sports, had faced a challenging life due to her disease. She required regular blood transfusions and took iron-reducing medication every day, which stifled her energy.
However, the new RM001 cell therapy offered a beacon of hope. In February, Xiao Lin became the first severe thalassemia patient to enroll in the clinical trial. Following her successful enrollment, she underwent RM001 cell gene editing treatment in June under the care of Fang and his dedicated pediatric team.
Her journey was not without obstacles. Throughout her hospitalization, she confronted infections, bleeding, hepatic vein obstruction, and endothelial damage, a type of coronary disease.
Despite these challenges, her resilience, combined with the meticulous care provided by Fang's team, enabled her to overcome these hurdles and emerge stronger.
Her parents, recognizing the significance of her medical journey, made the deliberate decision to prioritize her well-being by opting not to have a second child. Their unwavering support has been crucial in Xiao Lin's pursuit of a healthier future.
