Clinical Trials of Ogivri

Clinical Trial Results

Effect of a proposed trastuzumab biosimilar compared with trastuzumab on overall response rate in patients with ERBB2 (HER2)-positive metastatic breast cancer: A randomized clinical trial.

This phase 3, multicenter, randomized, parallel-group trial tested Ogivri versus the EU-licensed version of Herceptin. The manufacturers had also provided bridging studies to prove the equivalence of the US- to EU-licensed reference product.

The researchers’ primary endpoint for this study was overall response rate (ORR) at 24 weeks in patients with metastatic breast cancer who are also receiving taxane therapy. The secondary endpoints of progression-free survival (PFS) and safety and immunogenicity were also analyzed. The primary data analysis was performed on the intent-to-treat population. If patients experienced stable disease (SD), a complete or partial response, they were enrolled in a 24-week extension trial, in which their trastuzumab medications were given without taxanes once every three weeks until a 48-week cut-off.

The intent-to-treat population comprised 458 patients (230 in the biosimilar arm and 228 in the reference product or control arm). Patients in the biosimilar arm demonstrated an ORR of 70% compared with 64% in the control arm, which was within the predefined equivalence range. The median duration of response was 9.7 months (after 48 wk) for both treatment arms.

Results in the Intent-to-treat population:

  Ogivri + Taxane EU-Herceptin + Taxane
Complete Response 2% 0%
Partial Response 68% 64%
Overall Response Rate 70% 64%
Stable Disease 21% 21%
Overall Survival 89% 85%
Progression-Free Survival 44% 45%
Adverse Events 97% 95%
Neutropenia 57% 53%
Grade 3/4 Adverse Events 63% 63%
Antidrug Antibody Presence 2.4% 2.8%
None of these differences were statistically significant.

The investigators concluded that Ogivri and EU-licensed Herceptin yielded equivalent clinical and safety outcomes, and there were no meaningful differences between the drugs with respect to drug safety.

Current ongoing trials: None.
