Posology
Recommended Dosage for MCC
The recommended dose of Bavencio is 800 mg or 10 mg/kg body weight, according to treating physician’s discretion, administered as an intravenous infusion over 60 minutes every 2 weeks until disease progression or unacceptable toxicity.

Recommended Dosage for UC
The recommended dose of Bavencio is 800 mg or 10 mg/kg body weight, according to treating physician’s discretion, administered as an intravenous infusion over 60 minutes every 2 weeks until disease progression or unacceptable toxicity.

Recommended Dosage for RCC
The recommended dose of Bavencio is 800 mg or 10 mg/kg body weight, according to treating physician’s discretion, administered as an intravenous infusion over 60 minutes every 2 weeks in combination with axitinib 5 mg orally taken twice daily (12 hours apart) with or without food until disease progression or unacceptable toxicity.

When axitinib is used in combination with Bavencio, dose escalation of axitinib above the initial 5 mg dose may be considered at intervals of two weeks or longer. Review the Full Prescribing Information for axitinib prior to initiation.

Premedication
Patients have to be premedicated with an antihistamine and with paracetamol prior to the first 4 infusions of Bavencio. If the fourth infusion is completed without an infusion-related reaction,
premedication for subsequent doses should be administered at the discretion of the physician.

Treatment modifications
Dose escalation or reduction is not recommended. Dosing delay or discontinuation may be required based on individual safety and tolerability; see Table 1.

Detailed guidelines for the management of immune-related adverse reactions are described in section 4.4.

Treatment modifications when Bavencio is used in combination with axitinib If ALT or AST ≥ 3 times ULN but < 5 times ULN or total bilirubin ≥ 1.5 times ULN but < 3 times ULN, both Bavencio and axitinib should be withheld until these adverse reactions recover to Grades 0-1. If persistent (greater than 5 days), corticosteroid therapy with prednisone or equivalent followed by a taper should be considered. Rechallenge with Bavencio or axitinib or sequential rechallenge with both Bavencio and axitinib after recovery should be considered. Dose reduction according to the axitinib product information should be considered if rechallenging with axitinib.

If ALT or AST ≥ 5 times ULN or > 3 times ULN with concurrent total bilirubin ≥ 2 times ULN or total bilirubin ≥ 3 times ULN, both Bavencio and axitinib should be permanently discontinued and corticosteroid therapy should be considered.

Dose modification advice for axitinib when used with Bavencio
When Bavencio is administered in combination with axitinib, please refer to the axitinib product information for recommended dose modifications for axitinib.

Special populations

Elderly
No dose adjustment is needed for elderly patients (≥ 65 years) (see sections 5.1 and 5.2).
Paediatric population
The safety and efficacy of Bavencio in children and adolescents below 18 years of age have not been established.

Renal impairment
No dose adjustment is needed for patients with mild or moderate renal impairment (see section 5.2).
There are insufficient data in patients with severe renal impairment for dosing recommendations.

Hepatic impairment
No dose adjustment is needed for patients with mild hepatic impairment (see section 5.2). There are insufficient data in patients with moderate or severe hepatic impairment for dosing recommendations.

Method of administration
Bavencio is for intravenous infusion only. It must not be administered as an intravenous push or bolus injection.

Bavencio has to be diluted with either sodium chloride 9 mg/mL (0.9%) solution for injection or with sodium chloride 4.5 mg/mL (0.45%) solution for injection. It is administered over 60 minutes as an intravenous infusion using a sterile, non-pyrogenic, low-protein binding 0.2 micrometre in-line or add-on filter.
