Acerus Pharmaceuticals Corporation (TSX:ASP) (“Acerus” or the “Company”) is today providing results of a Phase 1 clinical trial (the “trial”) testing a proprietary intranasal formulation of a tetrahydrocannabinol (“THC”)-rich cannabis oil in healthy volunteers.

The THC trial, previously announced on October 24, 2018, involved 12 overnight-fasting, healthy subjects with prior cannabis experience. Each subject randomly received one 5mg dose of cannabis oil orally and an equivalent dose of cannabis oil nasally delivered through our proprietary intranasal formulation, with at least one week separating the two treatments.

Blood levels were measured and pharmacokinetic parameters of absorption and elimination were determined along with the comparative bioavailability of THC for the two routes of administration. Self-reported subject outcomes were also collected.


  • The nasal formulation was absorbed and resulted in extended PK profile with maximum peak levels (Tmax) occurring 7h after administration, on average;
  • Bioavailability of THC from the nasal formulation was approximately 2.2 times better than oral dronabinol capsules as described in recent literature (see Oh et al., Clinical Pharmacology: Advances and Applications 2017, 9, 9);
  • Additionally, a majority of subjects reported appreciation of several key features of the nasal product, including quick/easy use, consistent dosing, portability and absence of smoke.

“We are encouraged by the results of our Phase 1 study,” said Ed Gudaitis, President and CEO of Acerus Pharmaceuticals. “We believe that the adaptation of our proprietary nasal delivery system for cannabinoids validates our approach to developing safer, discreet and convenient cannabis products for the medical cannabis sector. Our goal is to develop a portfolio of cannabis products having THC and CBD in their compositions, in order to address a broad set of conditions. These products can be commercialized either through partnerships or through our own efforts.”
