Safety

The overall safety profile
of POLIVY-R-CHP is similar to that
of R-CHOP and consistent with the
known risk of the individual study drugs1

POLIVY-R-CHP had fewer cases of peripheral neuropathy leading to discontinuations (0.2% vs R-CHOP: 0.9%)1

Of patients who experienced any grade peripheral neuropathy, a lower percentage had Grade ≥2 or higher events with POLIVY-R-CHP compared with R-CHOP (POLIVY-R-CHP: 13.8% vs R-CHOP: 16.7%)1

Rates of febrile neutropenia were higher with POLIVY-R-CHP vs R-CHOP (14.3% vs 8.0%), but this did not translate into greater overall rates of infection: Grade 3 or 4 infections were comparable (15.2% vs 12.6%, respectively)1

*Top 5 most common adverse events, defined as AEs of any grade that occurred in at least 12% of the patients in either treatment group.   

Peripheral neuropathy includes the following preferred terms from the system organ class of peripheral neuropathy: peripheral neuropathy, peripheral sensory neuropathy, paresthesia, hypoesthesia, polyneuropathy, peripheral motor neuropathy, dysesthesia, neuralgia, peripheral sensorimotor neuropathy, hypotonia, hyporeflexia, neuromyopathy, ear paresthesia, peroneal nerve palsy, and skin burning sensation.

The percentage of grade 5 adverse events reported in POLIVY-R-CHP and R-CHOP, respectively: any grade 5 AE (3, 2.3), pneumonia (0.9,0.7) unexplained death (0.9,0.2), sepsis or septic shock (0.2,0.7), acute kidney injury (0.2,0), cardiac death (0.2,0), intestinal perforation (0.2,0), respiratory failure (0.2,0), multiple organ dysfunction syndrome (0,0.2), complete atrioventricular block (0,0.2), injury (0,0.2).1
