Decision

What was the decision based on
The decision was based on quality (chemistry and manufacturing), nonclinical (pharmacology and toxicology) and clinical (pharmacology, safety and efficacy) information submitted by the sponsor. The benefit-risk profile of Onbevzi was considered favourable for the therapeutic use approved.
A Phase I study in healthy male subjects demonstrated the similarity between Onbevzi and Avastin in terms of pharmacokinetic properties (drug absorption, distribution, metabolism, and excretion) while the steady-state serum concentration data in a clinical Phase III study provided evidence for the pharmacokinetic similarity in a representative patient population (metastatic or recurrent non-squamous NSCLC). The ability of Onbevzi to exert the same therapeutic effect and have the same safety profile as EU Avastin was demonstrated in a clinical Phase III study where Onbevzi and EU Avastin were compared in patients with metastatic or recurrent non-squamous NSCLC using "the overall response rate (ORR)" as the study endpoint. The ORR was equivalent in both groups.

Onbevzi should be given in combination with IFN alfa-2a (Roferon-A). The recommended IFN alfa-2a dose is 9 MIU three times a week, however, if 9 MIU is not tolerated, the dosage may be reduced to 6 MIU and further to 3 MIU three times a week
Grade IV Glioma
The recommended dose of Onbevzi is 10 mg/kg of body weight given once every 2 weeks or 15 mg/kg of body weight given once every 3 weeks as an IV infusion.
It is recommended that Onbevzi treatment be continued until progression of the underlying disease.
Epithelial Ovarian, Fallopian Tube or Primary Peritoneal Cancer
The recommended dose of Onbevzi administered as an IV infusion is as follows:
First line treatment: 15 mg/kg of body weight given once every 3 weeks in combination with carboplatin and paclitaxel for up to 6 cycles of treatment, followed by continued use of Onbevzi as single agent.
It is recommended that Onbevzi treatment be continued for a total of 15 months therapy or until disease progression, whichever occurs earlier.
Treatment of recurrent disease:
Platinum sensitive: 15 mg/kg of body weight given once every 3 weeks in combination with carboplatin and paclitaxel for 6 cycles (up to 8 cycles) followed by continued use of Onbevzi as a single agent until disease progression. Alternatively, 15 mg/kg of body weight given once every 3 weeks in combination with carboplatin and gemcitabine for 6 cycles (up to 10 cycles), followed by continued use of Onbevzi as single agent until disease progression.
Platinum resistant: 10 mg/kg body weight given once every 2 weeks when administered in combination with one of the following agents – paclitaxel or topotecan (given weekly) or pegylated liposomal doxorubicin. Alternatively, 15 mg/kg every 3 weeks when administered in combination with topotecan given on days 1 to 5, every 3 weeks.
It is recommended that treatment be continued until disease progression.
Cervical Cancer
Onbevzi is administered in combination with paclitaxel and cisplatin or, if cisplatin is not tolerated or not indicated, paclitaxel and topotecan. The recommended dose of Onbevzi is 15 mg/kg of body weight given once every 3 weeks as an IV infusion.
It is recommended that Onbevzi treatment be continued until progression of the underlying disease.

Cervical Cancer
Onbevzi (bevacizumab) in combination with paclitaxel and cisplatin is indicated for the treatment of persistent, recurrent or metastatic carcinoma of the cervix. Onbevzi (bevacizumab) in combination with paclitaxel and topotecan is an acceptable alternative where cisplatin is not tolerated or not indicated.
What is this medicine and how does it work
Onbevzi is a biosimilar medicine to Avastin (bevacizumab). Bevacizumab is a recombinant humanised monoclonal antibody that selectively binds to and neutralises the biologic activity of human vascular endothelial growth factor (VEGF) by binding to its receptors, Flt-1 and KDR, on the surface of endothelial cells. Neutralising the biologic activity of VEGF reduces blood vessel formation in tumours, thereby inhibiting tumour growth. Administration of bevacizumab to mice transplanted with human tumour cells resulted in extensive anti-tumour activity, including against colon, breast, pancreas and prostate cancer cells. Microvascular permeability (blood vessel "leakiness") was reduced potentially resulting in inhibition of metastatic disease (when tumour cells break away from the primary site, travel through the blood or lymph system, and form new tumors at a new site in the body).
