Item 7.01 Regulation FD Disclosure.
On December 15, 2020, Anavex Life Sciences Corp.

A copy of the press release is furnished as Exhibit 99.1 to this Current Report.
The information furnished to Item 7.01 of this Current Report, including Exhibit 99.1 hereto, shall not be considered “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liability of such section, nor shall it be incorporated by reference into future filings by the Company under the Securities Act of 1933, as amended, or under the Exchange Act, unless the Company expressly sets forth in such future filing that such information is to be considered “filed” or incorporated by reference therein.
Item 8.01 Other Events.
On December 15, 2020, the Company announced top-line results from a U.S. Phase 2 randomized, double-blind, placebo-controlled trial of ANAVEX®2-73 (blarcamesine) in adult female patients with Rett syndrome.
The primary endpoint of the trial was safety. The convenient oral liquid once-daily dosing of 5 mg ANAVEX®2-73 was well-tolerated and demonstrated dose-proportional PK (pharmacokinetics). Adverse events related to study drug were similar between ANAVEX®2-73 (13.3%) and placebo (10%), with no reported serious adverse events (SAEs). The safety profile of ANAVEX®2-73 in this trial is consistent with prior clinical trial data.
All secondary efficacy endpoints of the trial showed statistically significant and clinically meaningful sustained improvements for ANAVEX®2-73 compared to placebo, consisting of the Rett Syndrome Behaviour Questionnaire (RSBQ) (p = 0.048) and the Clinical Global Impression Improvement Scale (CGI-I) score (p = 0.014) in the intent-to-treat (ITT) population (n = 25). Statistically significant differences in patient symptoms between the active and placebo groups occurred as early as 4 weeks following the initiation of ANAVEX®2-73 administration. Improvements in RSBQ scores were correlated with parallel decreases (improvements) in glutamate plasma levels. ANAVEX®2-73 activates the sigma-1 receptor (SIGMAR1). Data suggests that activation of the sigma-1 receptor (SIGMAR1) is pivotal to restoring neural cell homeostasis and promoting neuroplasticity. Consistent with previous ANAVEX®2-73 clinical trials, patients carrying the common form of the SIGMAR1 gene treated with ANAVEX®2-73 experienced stronger improvements in the prespecified efficacy endpoints.
All twenty-five patients in this randomized study elected to enter a 12-week ANAVEX®2-73 extension study. The Company will be advancing its Expanded Access Policy in order to provide long-term therapy to current participants with Rett syndrome under an expanded access program for ANAVEX®2-73.
Based on the results in this first of its kind U.S. Phase 2 study in adult patients with Rett syndrome, the Company is planning to meet with FDA to discuss the approval pathway. There are no FDA-approved drugs for Rett syndrome. ANAVEX®2-73 has Fast Track designation, Rare Pediatric Disease designation and Orphan Drug designation from the FDA for the treatment of Rett syndrome and may be considered for accelerated approval.
ANAVEX®2-73 is currently being evaluated for Rett syndrome in two other ongoing placebo-controlled clinical studies: The Phase 2 AVATAR trial in adult Rett syndrome study and the EXCELLENCE Phase 2/3 pediatric Rett syndrome study.
The study evaluated the safety, pharmacokinetics and efficacy of ANAVEX®2-73 in 25 adult female patients diagnosed with Rett syndrome (positive MECP2 gene mutation).
ANAVEX®2-73 treatment yielded a statistically significant, drug exposure-dependent response in the RSBQ Total scores, when compared to placebo, in the ITT cohort (all participants, p = 0.048). 66.7% of ANAVEX®2-73 treated subjects showed a statistically significant improvement in drug exposure-dependent RSBQ response as compared to 10% of the subjects on placebo in the ITT cohort (all participants, p = 0.011). Improvements in this adult population with Rett syndrome, assessed by RSBQ Total scores, are considered clinically meaningful according to published criteria applied to neurodevelopmental disorders. ANAVEX®2-73 treatment resulted in a sustained improvement in CGI-I scores throughout the 7-week study, when compared to placebo in the ITT cohort (all participants, p = 0.014). 86.7% of ANAVEX®2-73 treated subjects showed a statistically significant CGI-I response, defined as sustained improvement to treatment, as compared to 40% of the subjects on placebo in the ITT cohort (all participants, p = 0.014).
ANAVEX®2-73 was found to be well tolerated with very good medication compliance during the trial. All 25 subjects completed the study. The overall incidence of patients who experienced adverse events related to study drug, which were mild, or moderate was 13.3% (2) for the ANAVEX®2-73 treatment group and 10% (1) for the placebo group. No serious treatment emergent adverse events were reported during the course of the trial. There were no clinically significant differences in vital signs, lab values and EKG parameters between the active drug and placebo groups. Collectively, the study results are consistent with the known safety profile of ANAVEX®2-73. There was no signal for increased risk for common disorder-related manifestations.
