Higher-Dose Maintenance With ERZOFRI 351 mg in Adults With Schizophrenia (ELEVATE)

4 november 2026 bijgewerkt door: Alejandro Alva

Exploratory Evaluation of ERZOFRI (Paliperidone Palmitate) 351 mg Q4W Maintenance in Higher-Need Patients With Schizophrenia: Clinical Global Improvement, Drug-Induced Parkinsonism, and Sexual Dysfunction Outcomes Over a 3-Month Treatment Period

This is a prospective, multicenter, open-label, single-arm study evaluating ERZOFRI (paliperidone palmitate) 351 mg administered every 4 weeks as maintenance treatment in approximately 40 adults with schizophrenia who experience symptom worsening before their next scheduled monthly injection despite receiving paliperidone palmitate 234 mg every 4 weeks.

Participants will receive ERZOFRI 351 mg on Day 1, Week 4, and Week 8 and will complete an end-of-study assessment at Week 12. The study will evaluate changes in clinical severity over 12 weeks and will also assess movement-related side effects and sexual functioning.

Inclusion Criteria:

  1. Adults aged 18-65 years with a DSM-5 diagnosis of schizophrenia.
  2. Currently receiving monthly paliperidone palmitate long-acting injectable (INVEGA SUSTENNA or ERZOFRI) at a dose of 234 mg every 4 weeks (Q4W) for at least 3 consecutive months before Screening.
  3. Clinician-documented symptom breakthrough, destabilization, or functional deterioration occurring before the scheduled 4-week injection interval during at least 2 of the 3 most recent monthly injection cycles (not necessarily consecutive). Documentation may include progress notes indicating symptom worsening in the final week before the next injection, unscheduled clinic or emergency department visits for psychiatric symptoms, as-needed medication use for breakthrough psychosis, or clinician judgment based on longitudinal care.
  4. Documented prior tolerability to oral paliperidone or oral risperidone.
  5. Clinical Global Impression-Severity (CGI-S) score ≥3 (mildly ill) and ≤6 (severely ill) at Baseline.
  6. Able and willing to independently provide written informed consent.

Exclusion Criteria:

  1. Known hypersensitivity to paliperidone, risperidone, or any ERZOFRI formulation excipient.
  2. Renal impairment, defined as creatinine clearance (CrCl) <50 mL/min.
  3. Hemoglobin A1c (HbA1c) ≥7.0% at Screening.
  4. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≥2 times the upper limit of normal (ULN) at Screening.
  5. Body mass index (BMI) >43 kg/m² at Screening.
  6. QT interval corrected using Fridericia's formula (QTcF) >450 milliseconds (ms) for males or >470 ms for females at Screening. A QTcF ≥480 ms is exclusionary regardless of sex.
  7. Other clinically significant electrocardiogram abnormalities, including serious ventricular arrhythmias, clinically significant conduction abnormalities, or evidence of unstable cardiovascular disease, as determined by the investigator.
  8. Other metabolic abnormalities or medical conditions that, in the investigator's judgment, represent active, uncontrolled disease that could compromise participant safety or suitability for study participation.
  9. Current or recent (within the past 30 days) participation in another interventional clinical trial.
  10. Severe substance use disorder within the past 6 months, according to DSM-5 criteria.
  11. Pregnant or breastfeeding women, or women of childbearing potential who are unwilling or unable to comply with protocol-specified contraception requirements throughout study participation and for 45 days following the final study injection.
  12. History of neuroleptic malignant syndrome (NMS) or tardive dyskinesia (TD) requiring treatment discontinuation.
  13. Current use of strong CYP3A4 and/or P-glycoprotein (P-gp) inducers, including carbamazepine, rifampin, or St. John's Wort.
  14. Imminent risk of harm to self or others, as assessed by the investigator.

Maatregel Beschrijving
Tijdsspanne
Mean Change From Baseline to Week 12 in Clinical Global Impression-Severity (CGI-S) Score
Tijdsspanne: Baseline (Day 1) and Week 12

Change in clinician-rated CGI-S score from Baseline (Day 1) to Week 12. The CGI-S is a 7-point scale assessing overall severity of mental illness, ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill patients). Negative changes from baseline indicate improvement.

Tijdsspanne
Patient Clinical Global Impression-Improvement (PCGI-I) Response
Tijdsspanne: Weeks 4, 8, and 12

Proportion of participants reporting a PCGI-I score ≤2 ("much improved" or "very much improved"). The PCGI-I is a 7-point patient-reported measure of perceived global improvement, ranging from 1 (very much improved) to 7 (very much worse). Lower scores indicate greater improvement.

Weeks 4, 8, and 12
Change From Baseline in Simpson-Angus Scale (SAS) Total Score
Tijdsspanne: Baseline, Week 4, Week 8, and Week 12

Change from baseline in total SAS score. The SAS is a 10-item clinician-rated scale assessing parkinsonian signs. Each item is scored from 0 (normal) to 4 (extreme), with total scores ranging from 0 to 40; higher scores indicate greater severity of parkinsonian symptoms.

Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) Items 1-7 Total Score
Tijdsspanne: Baseline, Week 4, Week 8, and Week 12

Change from baseline in the total score for AIMS Items 1-7. The AIMS is a clinician-rated scale assessing involuntary movements involving the facial/oral regions, extremities, and trunk. Items 1-7 are each scored from 0 (none) to 4 (severe), with higher scores indicating greater severity of involuntary movements. The total score for Items 1-7 ranges from 0 to 28.

Correlation Between Serum Prolactin Concentration and Arizona Sexual Experience Scale (ASEX) Total Score
Tijdsspanne: Week 12

Correlation between serum prolactin concentration (ng/mL) and sexual dysfunction assessed using the Arizona Sexual Experience Scale (ASEX) at Week 12. The ASEX is a five-item questionnaire with total scores ranging from 5 to 30; higher scores indicate greater sexual dysfunction. The relationship will be evaluated using Pearson or Spearman correlation coefficients, as appropriate.

Week 12
