Teva Wins FDA Approval For Schizophrenia Innovation

As World Mental Health Month draws global support for people with mental health conditions, healthcare providers are focusing on patient-centric drug innovation to provide a wider range of comfortable, accessible treatment options.
The FDA approval of Weltruza, produced by leading generic pharmaceutical provider Teva, signifies a milestone within schizophrenia treatment.
Teva describes Weltruza as the first once-monthly subcutaneous olanzapine formulation for adults with schizophrenia: combining the antipsychotic with long-acting injectable technology, it offers an alternative to daily oral medicines, which patients can face difficulty adhering to.
“I’m incredibly proud of our R&D team and everyone across Teva who helped make this possible,” writes Eric A. Hughes, CMO and Head of R&D at Teva, on LinkedIn. “I’m especially grateful to the patients who participated in our clinical trials and the investigators who partnered with us along the way.”
For Teva, Weltruza’s impending rollout represents a significant strategic achievement as the pharmaceutical company pivots towards developing its pipeline of innovative medicines.
- An estimated 2.2 million people in the US currently live with schizophrenia, a chronic mental health condition.
- The National Institute of Mental Health cites an average of 28.5 potential years of life lost among people affected by the condition.
- Schizophrenia can affect thinking, perception, emotional expression, motivation and social functioning, and frequently co-occurs with cardiovascular disease and diabetes.
- The condition costs the US around US$366.8bn annually, including US$291.8bn in indirect costs, including lost productivity.
- The antipsychotics olanzapine, aripiprazole and risperidone constitute the main treatment pathway for schizophrenia, typically delivered through daily oral medications.
A patient-friendly schizophrenia treatment
For people living with schizophrenia, maintaining a treatment plan involves navigating appointments, medication routines, side effects and the practical demands of everyday life.
Traditional treatment centres around daily oral doses of antipsychotic formulations to reduce symptoms, which include disruptive hallucinations and delusions. However, maintaining a consistent administration schedule can present a challenge, increasing the risk of relapse.
“Adherence continues to be a major barrier to stability,” explains Christoph Correll, Clinical Professor of Psychiatry at the Zucker School of Medicine at Hofstra/Northwell.
Olanzapine is also available as an intramuscular injectable, but administration requires post-injection monitoring and oral supplementation, which can prove disruptive.
Weltruza is an extended-release injectable suspension, delivered once a month. The drug’s delivery platform uses SteadyTeq, a proprietary copolymer technology developed by Medincell, to enable controlled, sustained release of olanzapine.
Requiring no loading doses, extended monitoring periods or additional booster medications, Teva aims to offer a lower-risk, reduced-disruption treatment option.
For some patients, Weltruza could provide a more accessible treatment routine: one that fits more comfortably around work, family responsibilities and community engagement.
“Weltruza was developed with the patient in mind from day one,” says Chris Fox, Executive Vice President and Head of Innovative Franchise at Teva.
The FDA decision was supported by SOLARIS, an eight-week placebo-controlled Phase 3 trial.
Teva reports that Weltruza secured improvements across three clinical measures: the Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impression–Severity scale (CGI-S) and the Personal and Social Performance scale (PSP). These assess schizophrenia symptoms, overall illness severity and social functioning, respectively.
“It is a powerful demonstration of what is possible when the needs of the patient guide the development of a truly innovative medicine,” Chris continues.
“Pivot to Growth”: Teva’s portfolio shift
For Teva, Weltruza’s approval represents more than a milestone in schizophrenia treatment; it also encompasses a milestone achievement within the company’s long-term growth strategy.
As a major generic drug provider, Teva faces several growth constraints, owing to a lack of flexibility and the effects of price erosion on generic margins.
In 2023, the company announced “Pivot to Growth” – its strategic shift towards innovative medicines, in order to broaden its portfolio and secure new growth opportunities.
The key targets of Teva’s strategy include:
- Target growth through innovative medicines, in order to reduce reliance on its traditional generics pipeline.
- Maintain generics as a core source of cash flow, while transferring research emphasis towards complex generics, biosimilars and higher-value opportunities.
- Prioritise R&D and develop differentiated treatments in areas like neuroscience and immunology to invest in long-term growth.
- Reduce costs by US$700m by simplifying operations and improving profit margins.
- Secure over US$5bn in innovative medicines revenue by 2030.
By scaling its existing novel medicines – including Austedo for involuntary movements and Ajovy for migraine prevention – Teva secured a 6% increase in revenues by 2024, and by 2025 its innovative portfolio constituted 30% of its core growth.
The approval of Weltruza marks a significant step as the company continues to diversify its product pipeline and expand its presence in neuroscience.
“This milestone truly reflects our Pivot To Growth strategy in action: accelerating our innovative pipeline through disciplined execution and translating promising science into meaningful therapies,” concludes Richard Francis, CEO of Teva, discussing Weltruza’s approval on LinkedIn.
“Together, we are continuing to build momentum across our innovative medicines portfolio to deliver impact where patients need it most.”
