- An application has been made by and the first cycle of systemic anti-cancer therapy with inotuzumab ozogamicin will be prescribed by a consultant specialist specifically trained and accredited in the use of systemic anti-cancer therapy
- The prescribing clinician is fully aware of the risk factors for inotuzumab ozogamicin inducing hepatotoxicity including veno-occlusive liver disease/sinusoidal obstruction syndrome and that this risk rises as the number of cycles administered increases
- The patient has relapsed or refractory CD22-positive B cell precursor acute lymphoblastic leukaemia (ALL). Please tick appropriate box as to which type of ALL the patient has: * Philadelphia chromosome negative ALL or * Philadelphia chromosome positive ALL in which case treatment with at least one second or third generation TKI must have also failed
- The patient has been previously treated with intensive combination chemotherapy as initial treatment with or without subsequent salvage chemotherapy or blinatumomab
- The patient is an adult* *note there is a separate Blueteq form to be used for inotuzumab ozogamicin in this indication in children

- The following treatment duration policy will apply to the use of inotuzumab ozogamicin: for those patients proceeding to a stem cell transplant (SCT), the recommended duration of treatment is 2 cycles. A 3rd cycle may be considered for those patients who do not achieve a complete remission (CR) or a CR with incomplete haematological recovery (CRi) and minimal residual disease negativity after 2 cycles. For patients not proceeding to a SCT, a maximum of 6 cycles of treatment may be administered. Patients who do not achieve a CR or CRi within 3 cycles should discontinue treatment
- Inotuzumab ozogamicin will be used as monotherapy
- No planned treatment breaks of more than 6 weeks beyond the expected cycle length are allowed (to allow any toxicity of current therapy to settle or intercurrent comorbidities to improve).* *Requests for continuation of treatment after unplanned treatment breaks over this duration should be made via the treatment break approval process
