In a Noninferiority Study, INVEGA HAFYERA™ Delayed Relapse as Effectively as INVEGA TRINZA®
Safety & Adverse Reactions
- 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 reactions
- 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%)

Of the 1036 Participants Who Entered the Initial Screening Phase, 702 Continued on to the 12-month, Randomized, Double-blind Phase of the Noninferiority Trial1-3
PP1M: paliperidone palmitate 1-month (INVEGA SUSTENNA®).
PP3M: paliperidone palmitate 3-month (INVEGA TRINZA®).
PP6M: paliperidone palmitate 6-month (INVEGA HAFYERA™).
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 phase.
INVEGA HAFYERA™ Was Noninferior to INVEGA TRINZA® After the 12-Month Double-blind Phase1,3
Key Inclusion Criteria4
- Age: 18 to 70 years
- Diagnosed with schizophrenia (per DSM-5) for at least 6 months before screening
- Receiving treatment with INVEGA SUSTENNA®, INVEGA TRINZA®, injectable risperidone, or any oral antipsychotic
- Total PANSS scores of <70 points at screening and at randomization
Key Exclusion Criteria4
- Receiving any form of involuntary treatment
- Suicide attempt within 12 months before screening or imminent risk of suicide or violent behavior
- DSM-5 diagnosis of moderate or severe substance use disorder (except for nicotine and caffeine) within 6 months of screening
- History of NMS or TD
- Unstable medical conditions
- History of unresponsiveness or intolerance to paliperidone/risperidone
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)
- 10-point increase in total PANSS score for 2 consecutive assessments (if baseline score was ≤40)
- 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
PANSS=Positive and Negative Syndrome Scale.
NMS=neuroleptic malignant syndrome.
*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.
