Description

MarketVue®: Tardive Dyskinesia (TD)

The MarketVue®: Tardive Dyskinesia (TD) market landscape report combines primary (KOL interviews and survey data) and secondary market research to empower strategic decision-making and provide a complete view of the market.
Every MarketVue® includes a disease overview, epidemiology (US and EU5), current treatment, unmet needs, pipeline and access and reimbursement chapter.

Topics covered in this report:
• Disease overview: Review the disease pathophysiology and potential druggable targets
• Epidemiology: Understand prevalence, diagnosed and drug-treated prevalence of the population and key market segments
• Current treatment: Understand the treatment decision tree and strengths and weaknesses of current on-label and off-label treatment
• Unmet needs: Identify opportunities to address treatment or disease management gaps
• Pipeline analysis: Compare current and emerging therapy clinical development strategy; their performance on efficacy, safety, and delivery metrics; and their potential to address unmet needs
• Value and access: Review the evidence needed to assess and communicate value to key stakeholders (e.g., providers, payers, regulators) and learn what competitors have done or are doing

Methodology:
Research for the MarketVue®: Tardive Dyskinesia (TD) report is supported by 7 qualitative interviews with key opinion leaders, a quantitative survey with 24 U.S. physicians and secondary research.

Geographies covered:
United States plus epidemiology for EU5 (France, Germany, Italy, Spain, United Kingdom)

Key companies mentioned:
• Teva Pharmaceuticals
• Neurocrine Biosciences
• Luye Pharma Group

Key drugs mentioned:
• Deutetrabenazine (Austedo)
• Valbenazine (Ingrezza)
• Clonazepam (Klonopin, Rivotril)
• Botulinum toxin injections (Botox)
• Reserpine (Serpasil)
• Tetrabenazine (Nitoman, Xenazine)
• LY03015
• Acamprosate calcium
• Sarizotan

Key takeaways from the report:
Tardive dyskinesia (TD) is a medication-induced neurological disorder which disrupts patients’ quality of life with complications that include:
• Tapping or shaking of the fingers and hands
• Puckering and frowning of the mouth and darting tongue
• Rapid or constant blinking
• Movements of the trunk
According to TD experts interviewed by REACH, most TD patients are well-controlled with one of the two FDA-approved VMAT2 inhibitors. Austedo and Ingrezza are viewed as comparable options due to their similar efficacy, side effect profiles, and now, dosing convenience with the introduction of Austedo extended-release tablets. Consequently, individual physician preference is driven most often by prior experience and familiarity with a drug.
Psychiatrist, U.S.: “I mean it’s amazing to see what they [VMAT2 inhibitors] can do to people who had suffered for many years and whose lives had been very much destroyed by [TD].”
The report indicates that given the success of Austedo and Ingrezza, clinicians do not perceive a high unmet need for novel TD treatments, which is also reflected in the sparse TD pipeline. However, experts say they have observed a rise in prescriptions for dopamine receptor blocking agents beyond use in schizophrenia, expanding to wider use in other conditions:
• Major depressive disorder
• Bipolar disorder
• Gastroparesis
• Behavior conditions (e.g., autism)
This suggests a potential surge in TD cases in the future which underscores the growing demand for efficacious medications that avoid directly inhibiting the dopamine pathway, working to effectively prevent TD.
Psychiatrist, U.S.: “The future is not treating TD. I think the future is not inducing it… we may solve the problem by just not having drugs that cause the problem to begin with.”

How Do Licenses Work?

How Do Licenses Work?

The primary function of a report license is to define how many people within a company are authorized to use the purchased report. This is separate to how a report might be delivered. Unless specifically identified otherwise, the purchase option is Single User. Below is a helpful description of that license, along with a sampling of others most commonly offered.

  • This license allows only one user to have access to and to use/read the report. It is not one user at a time or one user group; it is an individual who will be reading and utilizing the report.

  • This license allows for the entire purchasing company to read and use the report. This is the license level that would allow for a report to be placed on an internal company shared drive for access by all employees of that direct company. This license does not extend to parent or sister company use.

  • This license is designed to allow an entire department within a company full access to a report. The departmental license is a great option for companies that have more than one location and the department is spread out all over the country/world

  • This license is for companies that have one location where they want the report to be accessible by all employees within that physical location.

  • This is the most flexible of the licensing options. Some publishers will allow you to get a license for a preset number of people (typically 5). These licenses are ideal for small work groups.

License options are at the discretion of each publisher. As such, not all licenses indicated above are available for every product. If you are uncertain of the best license for your needs or would like a license that is not proactively available, please contact us and we will be happy to assist.
