Positive top-line results from Phase IIa trial of SPL026 in Major Depressive Disorder
New SPL026 trials underway and screening commenced in the first in-human study of SPL028
LONDON, Jan. 25, 2023 (GLOBE NEWSWIRE) -- Small Pharma Inc. (TSXV: DMT) (OTCQB: DMTTF) (the“ Company ” or“ Small Pharma ”), a biotechnology company focused on short-duration psychedelic-assisted therapies for mental health conditions, has today published its financial results for the three and nine months ended November 30, 2022. A full copy of the financial results can be found under the Company's profile on SEDAR at . Unless otherwise indicated, all currency references are in Canadian dollars.
Financial Highlights (including post-period events):
Cash on hand as of November 30, 2022 was $22.7 million. Cash is net of an unrealized foreign exchange loss of $2.3 million due to a strengthening of the Canadian dollar against the British pound sterling (“ GBP ”) during the 9 months ended November 30, 2022; however, as most of the Company's operating costs are incurred in GBP, the loss has little impact on the underlying cash burn of the Company. Cash used in operating activities was $5.4 million for the three months ended November 30, 2022. Operating expenses for the three months ended November 30, 2022 were $7.2 million. 1,788,000 common shares purchased and cancelled to date through the normal course issuer bid.
Recent Operational Highlights (including post-period events):
Ultra Short-Duration Psychedelic Program
Phase IIa trial investigated the safety and efficacy of intravenous (“ IV ”) SPL026, with supportive therapy, in 34 patients with moderate/severe Major Depressive Disorder (“ MDD ”). SPL026 demonstrated a rapid and durable antidepressant response, and a statistically significant and clinically relevant reduction in depressive symptoms versus placebo, as measured by the Montgomery-Åsberg Depression Rating Scale (“ MADRS ”).
Primary endpoint met with a statistically significant -7.4 point difference between SPL026 (21.5mg) and placebo at two-weeks post-dose, as measured by MADRS change from baseline (p=0.02). Antidepressant effect of SPL026 with supportive therapy demonstrated a rapid onset at one-week post-dose with a statistically significant difference in MADRS of -10.8 versus placebo (p=0.002). Durable antidepressant effect with a 57% remission* rate at 12-weeks following a single SPL026 dose with supportive therapy. No apparent differences identified in antidepressant effect between a one and two dose regimen of SPL026. Favourable safety and tolerability profile demonstrated with no drug-related serious adverse events reported. All adverse events related to treatment were considered mild or moderate. Preparations for Phase IIb international multi-site clinical trial of SPL026 in MDD continues, with anticipated initiation in H1 2023. Dosing commenced in December 2022 in Phase Ib drug interaction study which aims to assess the interaction between selective serotonin reuptake inhibitors (“ SSRIs ”) and SPL026 in patients with MDD. The open-label study will investigate the safety, tolerability, pharmacokinetics (“ PK ”), pharmacodynamics (“ PD ”) and exploratory efficacy of SPL026, alone or in combination with SSRIs.
Short-Duration Psychedelic Programs
First patient dosed in January 2023 in the Phase I study exploring intramuscular (“ IM ”) administration of SPL026. The study aims to compare the safety, tolerability, PK and PD of SPL026 delivered via IM versus IV administration in healthy volunteers. Participant screening has commenced in the Phase I study evaluating the safety, tolerability, PK and PD of SPL028, deuterated DMT with supportive therapy.
SPL026 drug candidate to be provided in support of a University College London (“ UCL ”) led neuroplasticity brain-imaging study, seeking to explore the impact of DMT-induced brain changes on cognition, behaviour, and well-being. The Understanding Neuroplasticity Induced by Tryptamines Project (the“ UNITy Project ”) will use Functional Magnetic Resonance Imaging (fMRI) to image the brain before, during and after a DMT or placebo infusion.
Continued expansion of Intellectual Property portfolio with patents granted across each of the Company's core areas of patent protection. Three new patents granted in fiscal Q3 increasing the total to 14 granted patents and over 90 applications pending, including:
Second U.S. patent granted, protecting the therapeutic composition of a small group of deuterated DMT compounds, with expected lifetime of exclusivity until April 2041. European patent granted protecting a manufacturing process for the preparation of synthetic DMT, DMT-related compounds and deuterated DMT analogs, including pipeline candidates SPL026 and SPL028. The Company has entered into a new services agreement dated January 24, 2023 (the“ Agreement ”) with Native Ads, Inc.

George Tziras, Chief Executive Officer of Small Pharma , said:“The positive SPL026 Phase IIa results provide us with confidence in advancing the SPL026 clinical development program and our portfolio of short-duration mental health treatments. In the third fiscal quarter we made strong progress across our clinical trials, with two new SPL026 studies now underway and patient screening initiated in our first in-human trial with SPL028. In the first half of 2023, we will be focused on advancing these programs with momentum and preparing to launch our international Phase IIb trial for SPL026 in a larger MDD population.”
About the SPL026 in MDD Phase IIa study
The two-staged Phase IIa study investigated the efficacy and safety of IV SPL026, with supportive therapy, in 34 moderate/severe MDD patients. This included a blinded, randomized, placebo-controlled phase where the primary endpoint was to assess the efficacy of a single 21.5mg dose of SPL026 with supportive therapy, versus placebo with therapy, at two-weeks post-dose. All study participants were then enrolled into an open-label phase, where they received a single 21.5mg dose of SPL026 with supportive therapy, and were followed-up for a further 12-weeks. Efficacy was assessed using MADRS, a widely used and accepted scale for assessing depression severity, and assessments were made by blinded independent raters.
