- Initial Approval Criteria 1
Submission of medical records (chart notes) related to the medical necessity criteria is REQUIRED on all requests for authorizations. Records will be reviewed at the time of submission. Please provide documentation related to diagnosis, step therapy, and clinical markers (i.e. genetic and mutational testing) supporting initiation when applicable. Please provide documentation via direct upload through the PA web portal or by fax. |

- Patient will be transfused prior to apheresis to a total Hb ≤ 11 g/dL and a HbS level <30% and patient will be transfused at least 8 weeks prior to initiation of myeloablative conditioning (with aforementioned Hb and HbS goals); AND
Sickle Cell Disease † Ф
- Patient has a confirmed diagnosis of sickle-cell disease (includes genotypes βS/βS or βS/β0 or βS/β+) as determined by one of the following:
- Identification of significant quantities of HbS with or without an additional abnormal β-globin chain variant by hemoglobin assay; OR
- Identification of biallelic HBB pathogenic variants where at least one allele is the p.Glu6Val pathogenic variant on molecular genetic testing; AND
- Patient has symptomatic disease despite treatment with hydroxyurea and add-on therapy (e.g., crizanlizumab, voxelotor, etc.); AND
- Patient experienced two or more vaso-occlusive event/crises (VOE/VOC)* in the previous year while adhering to the above therapy
*VOE/VOC is defined as an event requiring a visit to a medical facility for evaluation which results in a diagnosis of such being documented due to one (or more) of the following: acute pain, acute chest syndrome, acute splenic sequestration, acute hepatic sequestration, priapism lasting > 2 hours AND necessitating subsequent interventions such as opioid pain management, non-steroidal anti-inflammatory drugs, RBC transfusion, etc.
* Requests for subsequent use of exagamglogene after receipt of lovotibeglogene autotemcel will be evaluated on a case-by-case basis
