Item 7.01 Regulation FD Disclosure.


On August 2, 2022, Axcella Health Inc. (the “Company” or “Axcella”) issued a press release announcing top-line data from its Phase 2a clinical trial of AXA1125 for the treatment of Long COVID entitled “Axcella Announces Results from Phase 2a Clinical Trial for Long COVID.” The Company also hosted a conference call to discuss the top-line data results on Tuesday, August 2, 2022 at 8:00 a.m. Eastern Time. Copies of the press release and presentation are attached as Exhibits 99.1 and 99.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.


The information in this Item 7.01 and Exhibits 99.1 and 99.2 attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities and Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall they be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.


Item 8.01 Other Events.


On August 2, 2022, the Company reported topline results from the Phase 2a randomized, double-blind, placebo-controlled investigation to evaluate the efficacy and safety of AXA1125 in patients with fatigue related to Long COVID.


In the study, 41 subjects were enrolled and randomized to receive either 67.8 grams per day of AXA1125 (N=21) or a matched placebo (N=20) in two divided doses for 28 days, with a one-week safety follow-up period. All 41 subjects who started the study remained in the study to completion. Endpoints included phosphocreatine recovery time (PCrτ) following moderate exercise as assessed by 31P-magnetic resonance spectroscopy (MRS), which was included to assess mitochondrial function, and most importantly, clinically relevant endpoints including self-reported mental and physical fatigue as assessed by the Chalder Fatigue Questionnaire (CFQ-11), 6 minute walk test (6MWT) as well as serum lactate levels. The CFQ-11 is a validated patient reported outcome measure of fatigue that has been used in measuring patient impact in fatigue states such as chronic fatigue syndrome.


Subjects who received AXA1125 had improvements in measures of mental and physical fatigue that were both highly statistically significant and clinically relevant compared to those who received placebo. Mean changes in total, physical and mental scores in the CFQ-11 versus placebo were -4.30 (p=0.0039), -2.94 (p=0.0097) and -1.32 (p=0.0097), respectively. Clinically meaningful shifts in the severity of physical and mental fatigue were also noted in subjects who received AXA1125 compared to those who received placebo. There was a statistically significant correlation of improvement in fatigue score and greater distance achieved in the 6MWT (p=0.0027), an objective measure of physical ability, only observed in subjects who received AXA1125 when compared to those receiving placebo.





Baseline PCrτ among all subjects was significantly higher and had a higher degree of inter-subject variability (92.46 S + 35.3 S) than previously reported in the literature. These findings support the hypothesis that there is significant mitochondrial dysfunction in these patients but limits the utility of this parameter in a clinical trial. The trial did not meet its exploratory primary endpoint of showing a change from baseline to week four in the PCrτ recovery rate following moderate exercise between subjects receiving AXA1125 and placebo. There was a notable trend toward significant improvement in serum lactate levels after a 6MWT in AXA1125 subjects (p=0.0730). AXA1125 was safe and well tolerated with no significant emergent adverse events or serious adverse events reported by study subjects.
