Summary GTx-104 – novel intravenous nimodipine – well positioned to solve oral challenges and potentially displace oral as SoC Nimodipine is the SoC and clinically de-risked; however, significant unmet needs remain with available oral formulations Pivotal Phase 3 STRIVE-ON safety trial met primary endpoint; clinical evidence of GTx-104 benefit vs oral capsules 3 Executive Summary aSAH: aneurysmal Subarachnoid Hemorrhage. All dates based on calendar year in the presentation. GTx-104 | aSAH Potential to address a severe rare disease with efficient commercial organization; concentrated patient care Orphan Drug Status with the potential for seven-year market exclusivity and additional multi-layered IP protection Regulatory Update July 2026 FDA Type A meeting minutes received; advancing a targeted resubmission via dual-source manufacturing strategy

4 Path to NDA Resubmission Following FDA Type A Meeting A CMC and manufacturing matter — CRL did not identify any clinical safety or efficacy deficiencies and did not request additional clinical data The CRL in context What it is NOT • Not an efficacy or safety deficiency • Not a request for additional clinical trials or clinical data What it IS • cGMP compliance status of the current contract manufacturer — a facility-level matter, not a GTx-104 product-specific quality finding • Additional leachables data time points and excipient toxicology risk assessments Defined path to resubmission Current CDMO • Remediating facility cGMP matters and demonstrating inspection readiness; requires an FDA reinspection to verify remediation Second source — in parallel • Advancing technology transfer to a second-source CDMO in the United States — more than one route to a compliant registration site, reducing single-source dependence Non-clinical • Completing the required non-clinical studies Resubmission: We intend to resubmit once all items cited in the CRL are fully addressed; a resubmission may be supported by either contract manufacturer, or both. Updates: We will report progress as key milestones are achieved.

8 Substantial Shortcomings of Oral Nimodipine Sources: Nimodipine Prescribing Label, Sandow et al., Mahmoud et al., Abboud et al., Soppi et al., Rabaut et al., Ho et al., Fletcher Spaght market research . Administration Challenges • High dosing burden of 60mg (2 x 30mg capsules), 6 times per day • 45% of patients receive nimodipine through nasogastric tube (NGT) – often via capsule extraction • Capsule extraction and administration is labor intensive Dosing Interruption Increased Hypotension Too High Fatal Medication Errors • Inadvertent parenteral injection can result in death or serious life-threatening AEs • Highest risk with capsule extraction • NYMALIZE (oral liquid) tempers the risk of error, but has tolerability challenges (e.g., severe diarrhea) due to solubility limitations of nimodipine 3Sub-optimal Therapeutic Benefit with Oral Administration High Pharmacokinetic Variability • Inconsistent plasma concentration in both inter and intra subject • High first-pass metabolism, leads to low bioavailability and frequent dosing • Gastric motility issues and presence of food delay rate of absorption • Potentially negligible concentration with NGT administration Hypotension drives missed doses and diminished efficacy Blood Concentration 55% of patients do not receive the full daily dose due to hypotension Sub-optimal Outcomes Too Low

24 GTx-104 target product profile is seen as valuable for its improved tolerability, cost savings, and easy IV use – with broad formulary inclusion by P&T committee EFFICACY PHARMACOECONOMIC ROA (route of admin) “… The pro of Product X is certainly the efficacy endpoint. The fact that there is a reduction in hypotensive events. That is a pretty significant, 19% reduction …” - Neurointensivist, Stanford University “… The reduction in hypotensive events is meaningful. I could use it for patients who can not take nimodipine due to hypotensive episodes …” - Neurointensivist, Mount Sinai “… I would prefer to use Product X in every patient because one of the biggest reasons to not continue nimodipine is because of hypotension …” - Neurointensivist, Atlantic Health System Respondents emphasized that reduction in hypotension is meaningful, as it allows more patients to remain on therapy and avoid dose-limiting side effects HCPs highlighted that even modest reductions in ICU or ventilator time can have a significant impact on hospital costs, suggesting potential to deliver value beyond drug price—particularly given the high-cost aSAH care settings Immediate usability without NG tube placement was seen as an advantage, enabling earlier intervention, especially in unstable or intubated patients where time sensitive dosing is key “… From an economic standpoint, fewer days in the ICU or on a ventilator certainly could justify the cost of the drug. Even a reduction of a single day is relevant. When it gets to be 2 or 3 days, then it’s very impressive ...” - Neurosurgeon, USC “… A reduction in ventilator days is great for the patient in reducing their risk of infections and benefitting their financial bottom line. It’s also good for hospital costs …” - Critical Care Specialist, Intermountain Health “… Most hospitals are over capacity right now. Any reduction in ICU or ventilator days typically translates to shorter hospital days, which will benefit hospitals overall in terms of costs and resources …” - Neurointensivist, Boston Medical Center “… I definitely prefer IVs for critically ill patients than oral. You don’t have to worry about placing down an NG tube …” - Neurosurgeon, Westchester Medical Center “… Blood levels are more consistent from one dose to the other, which makes a whole lot of sense since it’s IV. It’s mostly maintaining a therapeutic level and being at the peak of concentration that is a major advantage of IV …” - Neurosurgeon, UCSF “… IV would be great because then you don’t have the NG tube anymore or you don’t need to rush for the NG tube because it’s such a pain every time …” - Neurosurgeon, UCSF Primary Market Research Insights (2Q 2025) Sources: Third party conducted interviews, research, and analysis
