The Functional Assessment of Cancer Therapy-Bone Marrow Transplant scale (FACT-BMT) is a quality of life instrument that assesses the effects of bone marrow transplantation (BMT) on a patient's physical, social/family, emotional, and functional well-being while taking into consideration BMT-specific concerns.
The assessment has different questions, each scored on a Likert scale from 0-4.
The overall score is computed by adding scores of the questions and falls in the range 0-148, with higher scores indicating higher levels of overall well-being.

Change in PRO Over Time Assessed Using Adult Sickle Cell Quality of Life Measurement System (ASCQ-Me) Score on Different Domains for Participants ≥18 and ≤35 Years of Age
Tidsramme: 2 years after exa-cel infusion
|
ASCQ-Me is a disease-specific HRQoL questionnaire for adults with sickle cell disease that assesses Emotional Impact, Pain Impact, Social Functioning Impact, Stiffness Impact, Sleep Impact, Pain Episode Frequency, and Pain Episode Severity.
Domain scores are reported as T-scores standardized to a reference population where mean = 50, and SD = 10.
A change of approximately 5 points (1/2 SD) is considered clinically meaningful.
An increase of 5 points indicates improvement for the impact domains, whereas a decrease of 5 points indicates improvement for the Pain Episode Frequency and Pain Episode Severity domains.
For impact domain items higher score indicates better HRQoL and lower disease burden.
For Pain items lower score indicates a better outcome.
Scores are interpreted relative to the reference population mean of 50, taking into account the direction of scoring for each domain.

Change in PRO Over Time Assessed Using Pediatric Quality of Life Inventory (PedsQL) for Participants Greater Than or Equal to (≥) 12 and Less Than (<) 18 Years of Age
Tidsramme: 2 years after Exa-cel infusion
|
PedsQL scores were used to assess quality of life of participants.
It is a standardized, generic instrument for measuring health related quality of life (HRQoL) in children and adolescents.
It includes different domains (Psychosocial health, physical functioning, emotional functioning, social functioning, and school functioning).
When completing the PedsQL questionnaires, respondents were asked to provide a response on a 5-point scale ranging from 0 (never a problem) to 4 (almost always a problem).
Responses were then transformed to a 0 to 100 score, with higher scores reflecting better quality of life.

Tidsramme: 2 years after exa-cel infusion
|
The PedsQL Sickle Cell Disease Module (PedsQL SCD) is a disease-specific module of the PedsQL.
The tool measures self-reported health-related quality of life in participants with SCD across 9 domains: pain and hurt, pain impact, pain management (mgmt), worry I, worry II, emotions, treatment, communication I, and communication II.
When completing the PedsQL SCD Module questionnaires, respondents were asked to provide a response on a 5-point scale ranging from 0 (never a problem) to 4 (almost always a problem).
Responses were then transformed to a 0 to 100 score, with higher scores reflecting better quality of life.
