Zelira Therapeutics Meets Primary Endpoints for Phase (1b/2a) Medicinal Cannabis Trial for Insomnia

by Feb 19, 2020News

  • 23 chronic insomnia patients treated with ZLT-101, Zelira’s proprietary and patented medicinal cannabis formulation, demonstrated statistically significant improvement in Insomnia Severity Index scores compared to placebo
  • Positive trial results an important milestone for Zelira
  • Poised to launch world’s first clinically validated medicinal cannabis product for insomnia in 2020
  • Expands Zelira’s product portfolio alongside the HOPE™ product range

Zelira Therapeutics Ltd (ASX: ZLD,OTCQB: ZLDAF), a global leader in the development of clinically validated cannabis medicines, today announced positive Phase 1b/2a results confirming that ZLT-101 therapy achieved the primary endpoint of a statistically significant improvement in Insomnia Severity Index scores in patients diagnosed with chronic insomnia.

The Phase 1b/2a trial recruited 24 chronic insomnia patients, aged between 25-70. The study was a randomised, double-blind, cross-over design involving 14 nights of ZTL-101 and 14 nights of placebo, separated by a one-week washout period. All participants underwent a monitored sensitivity test to a mixture of ZTL-101 and placebo prior to commencing dosing. When dosing commenced each participant was able to take a single (0.5ml of 11.5mg total cannabinoids) or double (1 ml of 23mg total cannabinoids) dose of the medication, delivered sublingually, according to their symptoms.

Of the 23 participants who completed the protocol, 12 (52%) chose to increase the ZTL-101 medication from a single dose (0.5ml/11.5mg total cannabinoids) to double dose (1.0ml/23mg total cannabinoids) of ZTL-101 (as measured on the 14th night). Sixteen participants (69.5%) were taking a double dose (1.0ml) of the placebo on the 14th night.

The primary study endpoints were: (1) safety of the medication based on adverse event reporting; and (2) insomnia symptoms as measured by the Insomnia Severity Index (ISI) at the end of each of the 14 night active medication/placebo periods.

Primary Endpoint 2: Significant Change in ISI Scores

Compared to baseline ISI scores (18.0±3.7) a significant decrease was observed following ZTL-101 (12.9±5.3, p<0.001) but not following placebo (18.0±4.3, p>0.05) (Figure 1 attached). The magnitude of decrease in ISI scores following ZTL-101 and placebo were 5.2±4.3 [Confidence Interval (CI) = 3.4 to 7.0] and 0.0±3.3 [CI = -1.8 to 1.9], respectively. The ISI scores following ZTL-101 and placebo were significantly different (p<0.001).

This study represents the most rigorous clinical trial ever undertaken to assess the therapeutic potential of medicinal cannabis to treat the symptoms of chronic insomnia.  It’s also the first trial to use the Insomnia Severity Index, arguably the current gold standard in this field, to measure the efficacy of a medicinal cannabis product to treat insomnia symptoms.  The fact that ZLT-101 treatment achieved a statistically significant improvement in ISI scores is very impressive, particularly given the relatively short two-week dosing window. The lack of serious adverse or persistent mild adverse events is also encouraging given the reported safety issues for several already approved insomnia therapies.  Taken together, these results suggest ZLT-101 has potential as a novel treatment for Insomnia.” commented Professor Peter Eastwood, Principal Investigator for the study, and Director at the Centre for Sleep Science at the University of Western Australia.

Dr Richard Hopkins, Managing Director ex-US markets said “We are delighted with the preliminary findings from this study.  Additional analyses are on-going and we expect to release a final report, including data from a comprehensive suite of secondary endpoints, by the end of March 2020 and thereafter, subsequent scientific publications based on the positive results from this study.  We would like to acknowledge the dedicated team at the UWA Sleep Centre and express our gratitude to the patients and supporting investigators/organisations who participated in the study.”

An estimated 70 million Americans have insomnia where the market for prescription and over-the-counter medications used to treat the condition generates over US$2 billion in annual revenue. Zelira is leading the development of clinically validated full spectrum cannabis medicines to access global markets for insomnia medications.

Osagie Imasogie, Chairman of Zelira, commented “The positive outcome to this trial represents an important milestone for Zelira and its commitment to address the unmet need for clinically validated cannabis medicines and offer more treatment options to physicians and patients.  Having successfully completed its recent merger, Zelira is now poised to rapidly commercialise the world’s first clinically validated cannabis medicine for insomnia into global markets in 2020, including the US, based on the positive results of this study.   

These positive results add ZLT-101 to the Zelira portfolio of commercialized and to be commercialized, revenue generating products derived from cannabinoids, such as HOPE™, in the US and globally, as a result of rigorous scientific work by the Zelira team. Zelira will continue to deploy its unique Launch, Learn and Develop strategy to launch more scientifically validated products, targeting various conditions, into the market in 2020.”

Next Steps:

A final report from the clinical study including an analysis of a comprehensive suite of secondary endpoints will be provided by end of March 2020. These results will inform the design of any future clinical studies.

Zelira will also seek to deploy its Launch, Learn and Develop strategy to commence supply of its clinically-validated insomnia formula in countries and states where medicinal cannabis has been legalised including Australia, the USA, Germany and the United Kingdom.

This announcement has been authorised by the Board.

Cannabinoid Hyperemesis Syndrome

Cannabinoid Hyperemesis Syndrome

Cannabinoid hyperemesis syndrome (CHS) is a condition that leads to repeated and severe bouts of vomiting. CHS is rare and only occurs in daily long-term users of cannabis. Because many healthcare workers are unaware of this condition, diagnosis is not always straightforward.
