Improvements in health-related quality of life in patients with severe sickle cell disease after exagamglogene autotemcel.
Trial report in Blood advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
abstractSevere sickle cell disease (SCD), an inherited blood disorder characterized by recurrent vaso-occlusive crises (VOCs), significantly impairs health-related quality of life (HRQoL). Exagamglogene autotemcel (exa-cel), a one-time, ex vivo CRISPR/Cas9 gene-edited cell therapy, eliminated VOCs in 97% of participants with severe SCD in the phase 3 CLIMB SCD-121 trial. Here, we describe changes in patient-reported outcomes (PROs) in 30 adults and 12 adolescents with ≥16 months follow-up. Adult PROs include EuroQol Quality of Life Scale-5 dimensions-5 levels of severity (EQ-5D-5L), Functional Assessment of Cancer Therapy Bone Marrow Transplant (FACT-BMT), Adult Sickle Cell Quality of Life Measurement Information System (ASCQ-Me), and 11-point pain Numerical Rating Scale (NRS). In adolescents, EuroQol Quality of Life Scale-5 dimensions-youth (EQ-5D-Y), Pediatric Quality of Life Inventory (PedsQL), and pain NRS were used. Adult EQ-5D-5L US and UK healthy utility index and EQ visual analog scale (VAS) scores, which were lower than general population norm at baseline, substantially improved by month 6 after exa-cel infusion and were sustained through month 36, with similar improvements in FACT-General (FACT-G) total and bone marrow transplant subscale. All FACT-G (physical, social/family, emotional, functional well-being) and ASCQ-Me (emotional, social functioning, stiffness, sleep impact) subscales showed clinically meaningful improvement, including ASCQ-Me pain subscales (impact, episode frequency, severity), with substantial decreases in pain episode frequency by month 6. Mean pain NRS score decreased by month 6 and was sustained. Consistent with adults, adolescents had improvements in mean EQ-5D-Y VAS score, PedsQL score, and pain NRS. Exa-cel led to broad and clinically meaningful HRQoL benefits in adults and adolescents with SCD. The CLIMB SCD-121 and CLIMB-131 trials were registered at www.clinicaltrials.gov as #NCT03745287 and #NCT04208529, respectively.
