PARSIPPANY, N.J., and TEL AVIV, Israel, Sept. 20, 2025 (GLOBE NEWSWIRE) — Teva Pharmaceuticals, a U.S. affiliate of Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA), today announced the presentation of 10 posters from its innovative schizophrenia medicines portfolio, including long-term safety data from the completed SOLARIS Phase 3 trial showing no incidence of post-injection delirium/sedation syndrome (PDSS) in study participants taking olanzapine LAI (TEV-‘749), a once-monthly, long-acting injectable (LAI) subcutaneous formulation of olanzapine.¹ New data evaluating UZEDY^®, an extended-release injectable suspension of risperidone for subcutaneous use every one or two months for the treatment of schizophrenia in adults, found that it was associated with a shorter length of hospitalization compared to a once-monthly intramuscular injection of Invega Sustenna^®.¹ No comparisons can be made regarding efficacy, safety, or any other clinical outcomes as this was not studied. The data were presented at the 2025 Psych Congress Annual Meeting, taking place from September 17–21, 2025, in San Diego, California.

“The first formulation of olanzapine was approved nearly 30 years ago and is now one of the most commonly prescribed daily oral medicines for the treatment of schizophrenia. With these long-term safety results from SOLARIS, olanzapine LAI (TEV-‘749) has the potential to address a critical treatment gap by introducing a new era of long-acting olanzapine treatment,” said Eric Hughes, MD, PhD, Executive Vice President, Global R&D and Chief Medical Officer at Teva. “Separate from olanzapine LAI (TEV-‘749), one of our latest UZEDY studies sought to understand its role during hospitalization, a delicate and vulnerable moment for people living with schizophrenia and their caregivers. The human impact of potentially shorter hospital stays, and healthcare cost savings are a true realization of Teva’s commitment to treatment innovations that help drive change for those living with complex neurological conditions.”

Article content

“These encouraging results from the SOLARIS trial show that olanzapine LAI (TEV-‘749) has the potential to be the first long-acting olanzapine treatment option that alleviates the risk of PDSS. As a clinician, this is a critical development for people living with schizophrenia who may not prefer, or have difficulties adhering to daily oral treatment options,” said Christoph Correll, MD, Professor of Psychiatry at the Zucker School of Medicine, Hempstead, NY and SOLARIS study coordinating investigator. “Olanzapine is a long-established treatment option for schizophrenia with a well-known safety and efficacy profile, and olanzapine LAI (TEV-‘749) is building on that legacy with an innovative long-acting formulation that may help fill a significant gap in the current treatment landscape.”

Olanzapine LAI (TEV-‘749) Data

Article content

Teva’s Phase 3 SOLARIS trial program (NCT05693935) comprised an 8-week, randomized, double-blind, placebo-controlled period (Period 1 [P1]) in 18–64-year-old participants (n=675) with schizophrenia, followed by an open-label, long-term safety period ≤48 weeks (P2). For P1, participants were randomized 1:1:1:1 to once-monthly olanzapine LAI (TEV-‘749) (318mg, n=169; 425mg, n=169; 531mg, n=169) or placebo (n=168).¹ For P2, P1 olanzapine LAI (TEV-‘749) participants retained their treatment; P1 placebo participants were re-randomized to olanzapine LAI (TEV-‘749) dose-groups.¹

Article content

Through Week 56, an integrated long-term safety analysis from the double-blind and open-label periods demonstrated a systemic safety profile for olanzapine LAI (TEV-‘749) that was consistent with second-generation antipsychotic class effects and other olanzapine formulations. Consistent with previous results, no PDSS events (suspected or confirmed) were reported (3,470 total injections).¹ Olanzapine LAI (TEV-‘749) utilizes SteadyTeq™, a copolymer technology proprietary to MedinCell that provides a controlled steady release of olanzapine.

Article content

Article content

Across olanzapine LAI (TEV-‘749) groups, one or more treatment-emergent adverse events (TEAE) were reported in 449 (74%) participants with 50 (8%) experiencing TEAEs leading to trial discontinuation. Serious AEs were reported in 36 (6%) participants.¹ Most commonly reported TEAEs were weight increased (36%); injection site reactions (ISRs; induration [12%], pain [12%], erythema [10%], pruritus [7%]); and somnolence (7%).¹

Article content

Additionally, long-term effectiveness data from SOLARIS demonstrated long-term symptom improvement and maintained clinical effectiveness in adult participants taking olanzapine LAI (TEV-‘749).¹ Across all olanzapine LAI (TEV-‘749) doses, stable change from P2 baseline in Positive and Negative Syndrome Scale (PANSS) total and Clinical Global Impression-Severity (CGI-S) scale scores (mean change from baseline: -7.2 and -0.5, respectively) were observed. Olanzapine LAI (TEV-‘749) also improved patient functioning scores, with a 4.6-point mean increase in Personal and Social Performance Scale (PSP) score from P2 baseline.¹

Article content

Article content

A weight and metabolic analysis of the SOLARIS trial found that long-term metabolic safety data for olanzapine LAI (TEV-‘749) were consistent with currently available olanzapine formulations.¹ The overall mean weight increase from baseline in participants who received olanzapine LAI (TEV-‘749) for ≥48 weeks (n=137) was 5.6kg, which was comparable to those reported for oral and intramuscular olanzapine formulations. By week 32, all olanzapine LAI (TEV-‘749) and placebo groups reached a similar mean weight increase versus baseline, which thereafter remained stable through week 48.¹

UZEDY Data

Article content

In a retrospective observational cohort study that included HCPs who prescribed UZEDY or Invega Sustenna^® (paliperidone palmitate) for patients with schizophrenia during hospitalization, found that the initiation of UZEDY (n=137) was associated with shorter hospital stays compared to Invega Sustenna^® (n=94).¹ UZEDY was associated with a 2.89-day shorter length of stay compared with Invega Sustenna^® (12.57 [SD:10.03] vs 15.46 days [10.15], P=0.033), which translates to estimated direct cost savings of $3,200 per hospitalization.¹ UZEDY was favored over Invega Sustenna^® for ease of administration (45% vs 34%), initiation (47% vs 33%), dosing characteristics (40% vs 38%), and subcutaneous injection features (40% vs 33%). Overall, 45% preferred UZEDY, while 38% preferred Invega Sustenna^®.¹

About Schizophrenia
Schizophrenia is a chronic, progressive and severely debilitating mental disorder that affects how one thinks, feels and acts.³ Patients experience an array of symptoms, which may include delusions, hallucinations, disorganized speech or behavior and impaired cognitive ability.^3,4,5 Approximately 1% of the world’s population will develop schizophrenia in their lifetime, and 3.5 million people in the U.S. are currently diagnosed with the condition.^4,5 Although schizophrenia can occur at any age, the average age of onset tends to be in the late teens to the early 20s for men, and the late 20s to early 30s for women.⁵ The long-term course of schizophrenia is marked by episodes of partial or full remission broken by relapses that often occur in the context of psychiatric emergency and require hospitalization.⁵ Approximately 80% of patients experience multiple relapses over the first five years of treatment, and each relapse carries a biological risk of loss of function, treatment refractoriness, and changes in brain morphology.^6,7,8 Patients are often unaware of their illness and its consequences, contributing to treatment nonadherence, high discontinuation rates, and ultimately, significant direct and indirect healthcare costs from subsequent relapses and hospitalizations.^3,4,5,6,7,8

IMPORTANT SAFETY INFORMATION CONTINUED

Article content

CONTRAINDICATIONS: UZEDY is contraindicated in patients with a known hypersensitivity to risperidone, its metabolite, paliperidone, or to any of its components. Hypersensitivity reactions, including anaphylactic reactions and angioedema, have been reported in patients treated with risperidone or paliperidone.

Article content

WARNINGS AND PRECAUTIONS

Article content

Cerebrovascular Adverse Reactions: In trials of elderly patients with dementia-related psychosis, there was a significantly higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, in patients treated with oral risperidone compared to placebo. UZEDY is not approved for use in patients with dementia-related psychosis.

Article content

Article content

Neuroleptic Malignant Syndrome (NMS): NMS, a potentially fatal symptom complex, has been reported in association with antipsychotic drugs. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status including delirium, and autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia). Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure. If NMS is suspected, immediately discontinue UZEDY and provide symptomatic treatment and monitoring.

Article content

Tardive Dyskinesia (TD): TD, a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements, may develop in patients treated with antipsychotic drugs. Although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to predict which patients will develop the syndrome. Whether antipsychotic drug products differ in their potential to cause TD is unknown.

Article content

The risk of developing TD and the likelihood that it will become irreversible are believed to increase with the duration of treatment and the cumulative dose. The syndrome can develop, after relatively brief treatment periods, even at low doses. It may also occur after discontinuation. TD may remit, partially or completely, if antipsychotic treatment is discontinued. Antipsychotic treatment, itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome, possibly masking the underlying process. The effect that symptomatic suppression has upon the long-term course of the syndrome is unknown.

Article content

Article content

If signs and symptoms of TD appear in a patient treated with UZEDY, drug discontinuation should be considered. However, some patients may require treatment with UZEDY despite the presence of the syndrome. In patients who do require chronic treatment, use the lowest dose and the shortest duration of treatment producing a satisfactory clinical response. Periodically reassess the need for continued treatment.

Article content

Metabolic Changes: Atypical antipsychotic drugs have been associated with metabolic changes that may increase cardiovascular/cerebrovascular risk. These metabolic changes include hyperglycemia, dyslipidemia, and body weight gain. While all of the drugs in the class have been shown to produce some metabolic changes, each drug has its own specific risk profile.

Article content

Hyperglycemia and diabetes mellitus (DM): in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, have been reported in patients treated with atypical antipsychotics, including risperidone. Patients with an established diagnosis of DM who are started on atypical antipsychotics, including UZEDY, should be monitored regularly for worsening of glucose control. Patients with risk factors for DM (e.g., obesity, family history of diabetes) who are starting treatment with atypical antipsychotics, including UZEDY, should undergo fasting blood glucose (FBG) testing at the beginning of treatment and periodically during treatment. Any patient treated with atypical antipsychotics, including UZEDY, should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics, including UZEDY, should undergo FBG testing. In some cases, hyperglycemia has resolved when the atypical antipsychotic, including risperidone, was discontinued; however, some patients required continuation of antidiabetic treatment despite discontinuation of risperidone.

Article content

Dyslipidemia has been observed in patients treated with atypical antipsychotics.

Article content

Weight gain has been observed with atypical antipsychotic use. Monitoring weight is recommended.

Article content

Hyperprolactinemia: As with other drugs that antagonize dopamine D₂ receptors, risperidone elevates prolactin levels and the elevation persists during chronic administration. Risperidone is associated with higher levels of prolactin elevation than other antipsychotic agents.

Article content

Orthostatic Hypotension and Syncope: UZEDY may induce orthostatic hypotension associated with dizziness, tachycardia, and in some patients, syncope. UZEDY should be used with particular caution in patients with known cardiovascular disease, cerebrovascular disease, and conditions which would predispose patients to hypotension and in the elderly and patients with renal or hepatic impairment. Monitoring of orthostatic vital signs should be considered in all such patients, and a dose reduction should be considered if hypotension occurs. Clinically significant hypotension has been observed with concomitant use of oral risperidone and antihypertensive medication.

Article content

Article content

Falls: Antipsychotics, including UZEDY, may cause somnolence, postural hypotension, motor and sensory instability, which may lead to falls and, consequently, fractures or other fall-related injuries. Somnolence, postural hypotension, motor and sensory instability have been reported with the use of risperidone. For patients, particularly the elderly, with diseases, conditions, or medications that could exacerbate these effects, assess the risk of falls when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic therapy.

Article content

Leukopenia, Neutropenia, and Agranulocytosis have been reported with antipsychotic agents, including risperidone. In patients with a pre-existing history of a clinically significant low white blood cell count (WBC) or absolute neutrophil count (ANC) or a history of drug-induced leukopenia or neutropenia, perform a complete blood count (CBC) frequently during the first few months of therapy. In such patients, consider discontinuation of UZEDY at the first sign of a clinically significant decline in WBC in the absence of other causative factors. Monitor patients with clinically significant neutropenia for fever or other symptoms or signs of infection and treat promptly if such symptoms or signs occur. Discontinue UZEDY in patients with ANC < 1000/mm³) and follow their WBC until recovery.

Article content

Article content

Potential for Cognitive and Motor Impairment: UZEDY, like other antipsychotics, may cause somnolence and has the potential to impair judgement, thinking, and motor skills. Somnolence was a commonly reported adverse reaction associated with oral risperidone treatment. Caution patients about operating hazardous machinery, including motor vehicles, until they are reasonably certain that treatment with UZEDY does not affect them adversely.

Article content

Seizures: During premarketing studies of oral risperidone in adult patients with schizophrenia, seizures occurred in 0.3% of patients (9 out of 2,607 patients), two in association with hyponatremia. Use UZEDY cautiously in patients with a history of seizures or other conditions that potentially lower the seizure threshold.

Article content

Dysphagia: Esophageal dysmotility and aspiration have been associated with antipsychotic drug use. Antipsychotic drugs, including UZEDY, should be used cautiously in patients at risk for aspiration.

Article content

Priapism has been reported during postmarketing surveillance for other risperidone products. A case of priapism was reported in premarket studies of UZEDY. Severe priapism may require surgical intervention.

Article content

Body temperature regulation. Disruption of the body’s ability to reduce core body temperature has been attributed to antipsychotic agents. Both hyperthermia and hypothermia have been reported in association with oral risperidone use. Strenuous exercise, exposure to extreme heat, dehydration, and anticholinergic medications may contribute to an elevation in core body temperature; use UZEDY with caution in patients who experience these conditions.

Article content

ADVERSE REACTIONS
The most common adverse reactions with risperidone (≥5% and greater than placebo) were parkinsonism, akathisia, dystonia, tremor, sedation, dizziness, anxiety, blurred vision, nausea, vomiting, upper abdominal pain, stomach discomfort, dyspepsia, diarrhea, salivary hypersecretion, constipation, dry mouth, increased appetite, increased weight, fatigue, rash, nasal congestion, upper respiratory tract infection, nasopharyngitis, and pharyngolaryngeal pain.
