Clinical research
Being tested in people in registered clinical trials. Being in trials is not evidence that a treatment works or is safe.
ما الذي تختبره هذه التجربة
The first American trial to give patients T cells edited with CRISPR. Three edits were made in each patient's own cells before they were returned. The main finding was that it could be done safely and that the edited cells survived for months, which was the question at that stage, not whether anyone was helped long term.
A first-in-human Phase 1 study at the University of Pennsylvania of autologous T cells with TRAC, TRBC and PDCD1 knocked out by CRISPR-Cas9 and an NY-ESO-1-directed transgenic receptor introduced, in refractory myeloma and sarcoma. Published in Science, it reported feasibility, an acceptable safety profile and persistence of edited cells for months.

ما الذي تعنيه نتيجة التجربة وما لا تعنيه
نتائج المراحل المبكرة مستقاة من أعداد صغيرة من المشاركين ومتابعة قصيرة الأمد. وقد تتغير مع زيادة المشاركين والوقت، والتجربة التي تستقطب مشاركين أو جارية أو حتى مكتملة لم تُثبت بعد نجاعة العلاج. معايير الالتحاق صارمة، وتُحدَّد الأهلية من قِبَل موقع التجربة لا من قِبَل أي موقع إلكتروني.
