Management Comments

• Scott Braunstein, M.D., Chairman and Chief Executive Officer, stated, 'Our unwavering commitment is to develop innovative treatment options for individuals with seizure disorders.'
• Dr. Braunstein also noted, 'With continued commercial success in CDD and a significant unmet need in drug-resistant epilepsies, we believe there is a robust market opportunity for the ZTALMY franchise.'
• Joseph Hulihan, M.D., Chief Medical Officer, said, 'We are optimistic that we can replicate the success of our pivotal CDD trial of ZTALMY in the TrustTSC study, where we believe refinements made to the Phase 3 titration schedule and low discontinuation rates throughout the trial suggest improved tolerability.'

Industry Context

This announcement highlights the growing market for treatments for rare seizure disorders. Marinus is positioning itself as a leader in this space, particularly with its focus on ganaxolone and its various formulations. The company's expansion into tuberous sclerosis complex (TSC) and other developmental and epileptic encephalopathies aligns with the industry trend of targeting specific genetic epilepsies with tailored therapies.

Comparison to Industry Standards

• Marinus's 125% year-over-year revenue growth for ZTALMY in Q1 2024 is a strong performance compared to many other pharmaceutical companies in the rare disease space, although direct comparisons are difficult due to the unique nature of each company's product portfolio and stage of development.
• The company's focus on expanding into new indications like TSC is similar to other companies that have successfully launched drugs for rare diseases, such as BioMarin with its various enzyme replacement therapies.
• The cost reduction measures implemented by Marinus are a common strategy for biotech companies to extend their cash runway, especially when facing upcoming clinical trial readouts and potential regulatory submissions. This is similar to strategies employed by companies like Sarepta Therapeutics and Ultragenyx.
• The company's projected full-year revenue of $33-$35 million for ZTALMY is a significant milestone, but it is still relatively small compared to larger pharmaceutical companies with blockbuster drugs. However, for a company focused on rare diseases, this is a positive sign of commercial traction.
• The discontinuation rate of approximately 7% in the TrustTSC trial is relatively low compared to some other epilepsy trials, suggesting good tolerability of the drug. This is a positive sign for the potential success of the trial.

Stakeholder Impact

• Shareholders will be impacted by the positive revenue growth and clinical trial progress, but also by the cost reduction measures and net loss.
• Employees will be impacted by the workforce reduction of approximately 20%.
• Patients with seizure disorders will benefit from the continued development and commercialization of ZTALMY.
• Customers will have increased access to ZTALMY as the company expands globally.
• Suppliers may be impacted by the company's cost reduction plans.
• Creditors will be impacted by the company's financial performance and cash runway.

Next Steps

• Complete enrollment in the Phase 3 TrustTSC trial by mid-May 2024.
• Announce topline results from the Phase 3 RAISE trial in early summer 2024.
• Engage with the FDA to discuss a potential filing strategy for the RAISE trial.
• Prepare for commercial launches of ZTALMY in select European countries in the second half of 2024.
• Initiate a proof-of-concept study for ZTALMY in developmental and epileptic encephalopathies in the first half of 2025.
• Submit a supplemental New Drug Application (NDA) to the FDA for TSC in April 2025.
• Continue to evaluate additional opportunities to further extend cash runway.
