Obinutuzumab jest humanizowanym przeciwciałem monoklonalnym typu II podklasy IgG1 skierowanym przeciwko CD20 i otrzymywanym poprzez humanizację mysiego przeciwciała macierzystego B-Ly1 i wytwarzanym z zastosowaniem technologii rekombinacji DNA w linii komórkowej pochodzącej z jajnika chomika chińskiego.

Clinical use:

The indication is granted market authorization based on objective response rate (ORR) demonstrated in a single-arm Phase II trial. Overall survival (OS) benefit in a single-arm trial cannot be confirmed.

In the pivotal trial, the majority of the clinical responses occurred within 16 weeks. Benefit of continued treatment should be regularly assessed, with the optimal duration of therapy varying for each individual patient.

Distribution Restrictions: ERIVEDGE is only available through a controlled distribution program called the ERIVEDGE Pregnancy Prevention Program (EPPP). For more information please contact the EPPP at 1-888-748-8926 or log onto rocheproplus.ca/en/products-resources/erivedge.html.

Geriatrics (≥65 years of age): Elderly patients should be treated with caution and monitored for adverse events.

Pediatrics (<18 years of age): The safety and efficacy of ERIVEDGE in pediatric patients has not been established. Irreversible premature fusion of the epiphyses and precocious puberty have been reported in pediatric patients exposed to ERIVEDGE. Premature fusion can progress after discontinuation of treatment. Due to safety concerns ERIVEDGE is contraindicated in children and adolescents aged below 18 years.

Contraindications:

Female patients who are pregnant or at risk of becoming pregnant

Breastfeeding female patients

Female patients of childbearing potential (FCBP) and male patients who do not comply with the ERIVEDGE Pregnancy Prevention Program

Children and adolescents aged less than 18 years of age

Patients who are hypersensitive to vismodegib or to any ingredient in the formulation

Most serious warnings and precautions:

Embryo-fetal death or severe birth defects: Can cause severe malformations, including craniofacial anomalies, midline defects and limb defects when administered to a female who is pregnant. Must not be used during pregnancy.

Effects on post-natal development: Irreversible premature fusion of the epiphyses (EPF) and precocious puberty have been reported in pediatric patients exposed to ERIVEDGE. In some cases of EPF, fusion progressed after drug discontinuation.

Renal impairment: The safety and efficacy of ERIVEDGE in patients with severe renal impairment have not been studied. No dedicated clinical studies have been conducted to evaluate the effect of mild, moderate and severe renal impairment on the pharmacokinetics of vismodegib.

Hepatic impairment: ERIVEDGE is not recommended for use in patients with severe hepatic impairment since limited data are available in these patients. ERIVEDGE should be used with caution in patients with mild and moderate hepatic impairment.

Other relevant warnings and precautions:

Effects on post-natal development

Blood donation: Patients must not donate blood while on treatment and for 24 months after discontinuation
