Anxiety Treatment Boom: GAD Therapies Poised for Multi-Billion Dollar Expansion

GAD Therapies Market Set to Explode to $4.26B by 2033 as Demand Rockets for Innovative Anxiety Solutions 

NEW YORK, March 5, 2026 /PRNewswire/ -- Market News Updates News Commentary - Treatments for Generalized Anxiety Disorder (GAD) are getting better and more accessible, which is good news for millions of people dealing with constant worry and stress. Traditional medications like anti-anxiety drugs and antidepressants still play a big role, but therapy options such as cognitive-behavioral therapy and mindfulness techniques are also helping people manage symptoms without relying only on medication. Digital mental health tools and telehealth visits are making treatment easier to access, especially for people who may not have nearby providers or prefer remote care.  Active Companies in the biotech space of interest include: Helus PharmaTM (NASDAQ: HELP) (Cboe CA: HELP), Acadia Healthcare Company, Inc. (NASDAQ: ACHC), Johnson & Johnson (NYSE: JNJ), BrainsWay Ltd. (NASDAQ: BWAY), Firefly Neuroscience, Inc. (NASDAQ: AIFF).

The market for anxiety treatments is growing as awareness of mental health increases and more people seek help. Industry estimates suggest the global market for GAD treatments was around $1.8 billion in 2023 and could grow to more than $4.26 billion by 2033, representing roughly 9% annual growth. This growth reflects rising demand for both traditional therapies and newer digital solutions that allow patients to receive care in more flexible and personalized ways. Experts also expect the broader anxiety treatment market to reach well over $12 billion to $17+ billion in the next decade as mental health care continues to expand.

Looking ahead, innovation in GAD therapies and investment in mental health solutions are likely to keep the market moving upward. New medications, improved psychotherapy techniques, and technology-driven tools are giving patients more options than ever before. As mental health care becomes more integrated into mainstream healthcare systems, companies and investors focused on this space may benefit from long-term growth while helping address one of the most common mental health conditions in the world.

Helus Pharma Announces Topline Results in Phase 2 Signal Detection Study for HLP004 in Patients with Generalized Anxiety Disorder

• Statistically significant (p<0.0001) and clinically meaningful improvement in Hamilton Anxiety Rating Scale ("HAM-A") of ~10 points on top of Standard of Care ("SoC") at 6 weeks
• Durable effects sustained through at least 6 months
• In Phase 1 trial most participants were ready for discharge within 3 hours (In Phase 1 study at 30 mg dose); Acute effects lasted ~90 minutes
• Generally well-tolerated, adverse events were transient, with no drug related serious adverse events recorded
• At six months, the pooled study population showed 67% responders and 39% of patients were in remission

Helus PharmaTM (NASDAQ: HELP) (Cboe CA: HELP) ("Helus"), a clinical-stage pharmaceutical company developing novel serotonergic agonists ("NSAs") for serious mental health conditions, today announced topline results from a Phase 2 signal detection study evaluating HLP004 as a potential treatment for adults with moderate-to-severe generalized anxiety disorder ("GAD") who remained symptomatic despite ongoing SoC antidepressant therapy, including selective serotonin reuptake inhibitors and related agents.

GAD affects more than 20 million adults in the United States, and approximately half of patients treated for GAD fail to respond to initial first-line therapy.2,3 No adjunctive pharmacologic treatment for GAD has ever been approved. No new monotherapy has been approved in almost two decades.

In the Phase 2 signal detection study, 36 patients were randomized 2-to-1 active-to-placebo to HLP004 20 mg or 2mg and received two intramuscular doses three weeks apart. Patients were followed through Week 12, with continued observational follow-up extending up to one year. Participants had an average baseline HAM-A score of 22 and a General Anxiety Disorder-7 score of greater than or equal to 10 at screening.

Key findings include:

• Clinically meaningful efficacy: Patients that received 20mg HLP004 adjunctive to SoC therapy achieved mean reduction of 10.4-points (p<0.0001) in the HAM-A from baseline at six weeks
• Efficacy in difficult to treat population: Study population consisted of moderate-to-severe patients who remained symptomatic despite ongoing antidepressant or anxiolytic therapy
• Durable remission and robust response over time:
  • At six months, the pooled study population showed 67% responders and 39% remitters
  • Participants randomized to both 20 mg and 2mg dosing arms experienced meaningful subjective effects and showed clinically significant responses over SoC, with 59% meeting the criteria for response and 32% for remission in the 20mg arm and a 30% responder and remitter rate in the 2mg arm at week 6.
• Commercially scalable clinic time: Short in-clinic treatment experience with acute drug effects lasting approximately 90 minutes and discharge readiness within approximately three hours (In Phase 1 study at 30 mg dose), fitting within the treatment paradigm of existing interventional psychiatry clinics.
• Well tolerated: Favorable tolerability profile with no drug-related serious adverse events or suicidality-related safety signals

"These Phase 2 results support the continued development of HLP004, and I am encouraged by the magnitude of improvement observed over standard of care treatments, together with the rapid onset and short in-clinic treatment experience for this patient population with limited options," noted Dr. Andrew Cutler, Clinical Professor of Psychiatry at SUNY Upstate Medical University and Senior Advisor to Helus Pharma.

Michael Cola, Chief Executive Officer of Helus Pharma said "Patients living with generalized anxiety disorder remain significantly underserved, with many continuing to struggle despite currently available treatments. We are encouraged by these data and the potential for HLP004 to bring hope to GAD patients. The Company's broad intellectual property portfolio has been leveraged once again to create what we feel are best in class products and we are further excited to release the data on HLP003 targeted at major depressive disorder in the fourth quarter of 2026."  Continued…  Read this full release and additional news for Helus PharmaTM by visiting: https://ir.helus.com/investors/news/default.aspx
