Efficacy | INVEGA HAFYERA™ (paliperidone palmitate) HCP

INVEGA HAFYERA® Was Evaluated in a 1-year, Noninferiority Study and a 2-year, Open-label Extension Study

In a Noninferiority Study, INVEGA HAFYERA® Delayed Relapse as Effectively as INVEGA TRINZA®

1-year pivotal noninferiority study: 92.5% of patients taking INVEGA HAFYERA™ remained relapse-free

Results of a 12-month, randomized, double-blind, noninferiority trial. The primary efficacy variable was time to first relapse in the double-blind study.

A total of 702 stabilized patients were randomized in a 2:1 ratio to receive INVEGA HAFYERA® (n=478) or INVEGA TRINZA® (n=224) over the 12-month, double-blind study.2

Safety and Adverse Reactions: Noninferiority Study

  • In the double-blind phase, 1.3% of patients in the INVEGA HAFYERA® group and 0.4% of patients in the INVEGA TRINZA® group discontinued due to adverse events
  • The most common adverse reactions (≥5%) in the INVEGA HAFYERA® group were upper respiratory tract infection (12%), injection-site reaction (11%), weight increased (9%), headache (7%), and extrapyramidal symptoms† (7%)
  • The most common adverse reactions (≥5%) in the INVEGA TRINZA® group were upper respiratory tract infection (13%), weight increased (8%), injection-site reaction (5%), extrapyramidal symptoms* (5%), and headache (5%)

*Extrapyramidal symptoms include: blepharospasms, bradykinesia, drooling, dyskinesia, dystonia, hypokinesia, musculoskeletal stiffness, muscle rigidity, muscle spasms, oculogyric crisis, parkinsonism, parkinsonism rest tremor, reduced facial expression, tardive dyskinesia.

Patients Who Were Relapse-free for 1 Year in the Pivotal Study Were Eligible to Enter the Open-label Extension Study for 2 Years3

178 patients who were relapse-free on INVEGA HAFYERA® (n=121) or INVEGA TRINZA® (n=57) in the double-blind phase chose to continue treatment with INVEGA HAFYERA® in the open-label extension.3

2-year real-world, open-label extension safety and tolerability study

Safety and Adverse Events: Open-label Extension Study

  • The most common (≥5%) treatment-emergent adverse events were headache (13.5%), blood prolactin increased (10.7%), hyperprolactinemia (7.3%), diarrhea (6.2%), weight increased (5.1%), and nasopharyngitis (5.1%)3§

Relapse Criteria1-3

Relapse was defined as any of the following:

  • Psychiatric hospitalization
  • Increase of ≥25% in total PANSS score from randomization for 2 consecutive assessments (if baseline score was >40) (pivotal study only)
  • 10-point increase in total PANSS score for 2 consecutive assessments (if baseline score was ≤40) (pivotal study only)
  • Deliberate self-injury, violent behavior, or suicidal/homicidal ideation
  • Score of ≥5 (if the maximum baseline score was ≤3) or ≥6 (if the maximum baseline score was 4) on 2 consecutive assessments of the specific PANSS items
  • Emergency department/room/ward visit due to a worsening of the subject’s symptoms of schizophrenia (OLE only)
