Webinar. BIO (Biotechnology Innovation Organization, an industry group) sponsored a webinar titled, “Long COVID:  What Will It Take To Accelerate Therapeutic Progress?” Speakers included officials from government, academia, and drug development companies to discuss the scientific basis of the condition, its public health implications, and its potential treatments.  Presenting companies included Axcella Health (AXLA) and Tonix Pharmaceuticals (TNXP).

Long COVID Symptoms and Prevalence.  The program began with how Long COVID became recognized as a condition, its incidence, and its patient population. Scientific presentations showed the biological effects of the SARS-CoV-2 virus on cells in the body, including the connection between Long COVID and other chronic conditions such as CFS/ME (chronic fatigue syndrome/myalgic encephalomyelitis). Symptoms and their duration can vary widely, including inflammation, fatigue, organ dysfunction, and reactivation of latent viral reservoirs.  The presenters agreed that the range of symptoms and their variability will require numerous drugs.

Axcella Health Presented AXA1125. Chief Scientific Officer at Axcella Health, Dr. Margaret Koziel, presented the scientific basis for the use of AXA1125 in Long COVID, including its effects on inflammation, mitochondrial dysfunction, and fatigue.  Data from the Phase 2a trial was presented, showing improvements in function, and biomarkers that correlate with reductions in inflammation and mitochondrial dysfunction. The design of the Phase 2b/3 trial was also presented.

Tonix Pharmaceuticals Presented Data From TNX-102 SL. Tonix is currently enrolling patients in its Phase 2 PREVAIL trial testing TNX-102 SL, sublingual cyclobenzaprine, in Long COVID. This trial is based on common symptoms with fibromyalgia and chronic fatigue syndrome, such as pain, fatigue, and insomnia.  Projected enrollment is about 470 patients with a primary endpoint of change in daily pain score from baseline over the 14-week treatment period.

Conclusion. The BIO webinar speakers agreed that the high variability and large population would require several drugs to adequately treat patients. For Axcella, we believe the presentation could raise awareness of AXA1125 and its “Phase 2b/3 Ready” status, allowing it obtain trial funding through partnerships, government funding, or from investors.  Tonix was able to present how TNX-102 SL overlaps with other pain syndromes and how it could treat symptoms, as well as to highlight its clinical milestones in the coming year.

Summary. BIO (Biotechnology Innovation Organization, and industry group) sponsored a webinar titled, “Long COVID: What Will It Take To Accelerate Therapeutic Progress?” Speakers included officials from government, academia, and drug development companies to discuss the scientific basis of the condition, its public health implications, and its potential treatments.  Presenting companies included Axcella Health (AXLS) and Tonix Pharmaceuticals (TNXP).

The program began with the history of Long COVID, how it became recognized as a condition, and its prevalence. Scientific presentations discussed the SARS-CoV-2 viral infection and its effects on different organs, as well as the mechanisms of infection that lead to fatigue, cerebral effects (brain fog), and chronic pain.  The speakers pointed out that the range and severity of symptoms can vary widely, making it likely that numerous drugs will be needed.

The overlap between Long COVID and other chronic conditions, such as CFS/ME (chronic fatigue syndrome/myalgic encephalomyelitis), was also discussed. The common features in these conditions were cited in the “National Research Action Plan on Long COVID”, published by the Department of Health and Human Services in August 2022.

Axcella Health Spoke About AXA1125. Chief Scientific Officer at Axcella Health, Dr. Margaret Koziel, presented the scientific basis for the use of AXA1125 in Long COVID, including its effect on inflammation, mitochondrial dysfunction, epithelial dysfunction, and fatigue. Data from the Phase 2a trial was presented, showing improvements in physical and mental function.  These data included biomarkers that correlate with improvements in inflammation and mitochondrial function. The design of the Phase 2b/3 trial was also presented.

Tonix Pharmaceuticals Presented Data From TNX-102 SL. Tonix is currently enrolling patients in its Phase 2 PREVAIL trial testing TNX-102 SL, sublingual cyclobenzaprine, in Long COVID. This trial is based on common symptoms with fibromyalgia and chronic fatigue syndrome, such as pain, fatigue, and insomnia.  Projected enrollment is about 470 patients with a primary endpoint of change in daily pain score from baseline over the 14-week treatment period.

TNX-102 SL showed positive results in its Phase 3 RELIEF study in fibromyalgia, although the confirmatory Phase 3 RALLY missed its primary endpoint.  After analyzing the RALLY trial, the Phase 3 RESILIENT trial began.  An interim analysis from the RESILIENT trial is expected in 2Q23. 

Conclusion. The BIO webinar gave different perspectives on Long COVID and discussed different approaches to treatment. For Axcella, we believe the presentation could raise awareness of AXA1125 data and its “Phase 2b/3” ready status, allowing it obtain trial funding through partnerships, government funding, or from investors.  For Tonix, presentations on the common features of Long COVID and chronic pain syndromes support the use of Tonix’s TNX-102 SL, and show how its Phase 2 PREVAIL clinical trial design could become an effective treatment.
