Small Pharma Reports Positive Top-line Results from Phase IIa Trial of SPL026 in Major Depressive Disorder

First placebo-controlled efficacy study completed to date exploring a short-duration psychedelic for depression demonstrates rapid and durable response

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

Company to host conference call at 8:30am (EST) / 1:30pm (GMT) January 25, 2023 to discuss results

January 25, 2023 – London, United Kingdom – 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, today announces that SPL026, intravenous N,N-Dimethyltryptamine (“DMT”), with supportive therapy for the treatment of Major Depressive Disorder (“MDD”) met the primary endpoint in its Phase IIa clinical trial, demonstrating a statistically significant and clinically relevant reduction in depressive symptoms at two-weeks post-dose, as compared to placebo. Further analysis of key secondary endpoints demonstrated a rapid and durable antidepressant effect to 12-weeks.

The trial investigated the efficacy and safety of intravenous (“IV”) SPL026, with supportive therapy, in 34 patients with moderate/severe MDD. Participants who entered the trial on pharmacological antidepressant medication were withdrawn from their treatment prior to dosing. Patients were dosed with a short IV infusion of 21.5mg of SPL026, resulting in a 20 to 30-minute psychedelic experience. The dose was selected as a result of data analysis from the Company’s Phase I study confirming that it was well tolerated and delivered a consistent psychedelic experience in healthy volunteers. 

The two-staged Phase IIa study included a blinded, randomized, placebo-controlled phase, where the primary endpoint was to assess the efficacy of a single dose of SPL026 with supportive therapy (N=17) versus placebo with therapy (N=17) at two-weeks post-dose. All study participants were subsequently enrolled into an open-label phase of the study where they received a single dose of SPL026 with supportive therapy, and were followed-up for a further 12-weeks in study**. This open-label trial design enabled the assessment of durability of antidepressant effect, as well as the comparative efficacy and safety of a one versus two dose regimen of SPL026. 

Efficacy was assessed using the Montgomery-Asberg Depression Rating scale (“MADRS”) to measure any potential change in patients’ depression from baseline. MADRS was assessed by independent raters who were not present at dosing and were blinded to the overall treatment.

The Phase IIa study met the primary endpoint demonstrating a statistically significant and clinically relevant reduction in depressive symptoms two-weeks following a dose of SPL026 with supportive therapy, compared to placebo, demonstrating a -7.4 point difference in MADRS (p=0.02). Analysis of key secondary endpoints demonstrated a rapid onset of antidepressant effect one-week post-dose, with a statistically significant difference in MADRS score between the active and placebo groups of -10.8 (p=0.002).

Across the 12-week open-label phase, patients who received at least one active dose of SPL026 with supportive therapy reported a durable improvement in depression symptoms. No apparent difference in antidepressant effect was observed between a one and two dose regimen of SPL026. The total mean reduction in MADRS from baseline after a single dose of SPL026 was –15.4 at 12-weeks.

Dr. Carol Routledge, Chief Medical and Scientific Officer said: “We are pleased that a significant number of patients benefited from the treatment in our trial. SPL026 with supportive therapy was shown to have a significant antidepressant effect that was rapid and durable, with a remission rate of 57% at three months following a single dose of SPL026. It was encouraging to see that SPL026 demonstrated a favourable safety and tolerability profile in MDD patients in this study, consistent with our Phase I study. The results are clinically meaningful and enable us to progress into an international multi-site Phase IIb study where we seek to further explore the efficacy and safety profile of SPL026 in a larger MDD patient population.”

Key Findings

1 Small Pharma Reports Positive Top-line Results from Phase IIa Trial of SPL026 in Major Depressive Disorder

 

 

 

 

 

 

Notes:

  1. a) refers to weeks following dose administered in either the blinded or open-label phase

Rapid onset of antidepressant effect

  • Primary endpoint met with a statistically significant -7.4 point difference between SPL026 and placebo (p=0.02) at two-weeks post-dose, as measured by MADRS change from baseline
  • Statistically significant -10.8 point difference between SPL026 and placebo (p=0.002) at one-week post-dose, as measured by MADRS change from baseline
  • Clinically meaningful difference in response* rates of SPL026 at week one and week two, 44% and 35%, respectively
  • Clinically meaningful difference in remission rates of SPL026 at week one and week two of 44% and 29%, respectively

Durability of antidepressant effect

  • Durability was measured by a change in MADRS from the original baseline of the study, at one, two, four and 12-weeks after the open-label dose of SPL026
  • Durable improvement in depression symptoms from baseline in groups receiving at least one dose of SPL026 observed to 12-weeks following the open-label dose
  • No apparent differences identified in antidepressant effect between a one and two dose regimen of SPL026
  • Treatment group receiving an open-label dose of SPL026 following placebo showed:
    • Total change in MADRS from baseline of -10.6 and -15.4 at one and 12-weeks post open-label dose
    • Durable response rate from week 1 (43%) to week 12 (50%) post dose
    • Durable remission rate from week 1 (43%) to week 12 (57%) post dose

Safety and tolerability

  • SPL026 was well tolerated by all patients receiving an active dose 
  • No drug-related serious adverse events reported, including no reported suicidal ideation or behaviour 
  • Adverse events (“AEs”) deemed possibly related to treatment in the blinded phase:
  • 19 in the SPL026 group
  • 4 in the placebo group
  • All were deemed mild or moderate in severity
  • 24 AEs deemed possibly related to treatment in the open-label phase 
  • Majority of drug-related AEs (~80%) resolved during the dosing visit
  • No clinically significant safety concerns in any treatment group, including with vital signs, electrocardiogram (ECG) or clinical laboratory findings 

The detailed results of the Phase IIa trial are expected to be presented at upcoming scientific meetings and published in a peer-reviewed journal.

George Tziras, Chief Executive Officer of Small Pharma said: “MDD affects the lives of hundreds of millions of people worldwide. The scale of the unmet need indicates the importance of investigating alternative new treatments. Our goal is to develop proprietary, scalable and reimbursable short-duration psychedelics with supportive therapy to address this need. I am delighted with our top-line results, which demonstrate proof-of-concept for SPL026 and provide encouraging support for our broader portfolio. I want to thank each patient who took part in this trial, as well as their families, the trial investigators, the employees of the trial sites and everyone who has supported the successful completion of this study.”

Dr. David Erritzoe Clinical Psychiatrist at Imperial College London and Chief Investigator of the Phase I/IIa study added: “The results are exciting for the field of psychiatry. We now have the first evidence that SPL026 DMT, combined with supportive therapy, may be effective for people suffering from MDD. For patients who are unfortunate to experience little benefit from existing antidepressants, the potential for rapid and durable relief from a single treatment, as shown in this trial, is very promising.”
