The HERITAGE trial: Designed per FDA guidelines to
detect any potentially clinically meaningful
difference
between OGIVRI® and reference
trastuzumab9
A confirmatory, double-blind, phase 3
equivalence trial in patients
with HER2+ metastatic breast cancer10
Study Endpoints
-
Primary endpoint was week 24 ORR (complete and
partial response
)10
-
Other endpoints included adverse events, LVEF,
and immunogenicity at week
24 and 48 and PFS and OS at month
36 2,10
Baseline Characteristics
-
Demographic, disease, and baseline
characteristics were similar between
treatment groups with no clinically relevant
differences observed.10
The Heritage Study experience… could serve
as a
blueprint for development of other biosimilar
products.
