Observational Study Report

Observational Study data from the last review, dated April 2021
  • An interim analysis of 119 patients who have completed six and 12-month administration of the NanoCelle® THC/CBD oral buccal spray has shown a 55%^ reduction in pain scores, with significant quality of life improvements also reported in the areas of sleep, mood and general activities.

  • It is the fifth monitoring report on the 12-month study and complements results from the earlier Phase I Royal North Shore Hospital pilot study in New South Wales.

  • Medlab has recruited almost 40% (or 801 people) of a total 2000 participants into the observational study, ranging in age from 21 years to 99 years with females representing 59% of the intake.

  • Approximately 3% of the 801 participants presented with cancer-induced bone pain, with 99% registering chronic pain and 1% with acute pain.

  • Preliminary analysis of their Brief Pain Inventory (BPI) scores after six and 12 months showed improvement in mean pain scores from 6.5 at the commencement of the study; to 5.5 at six months; and 4.7 at 12 months.

  • Of the 119 patients (65% female; 35% male) who have completed six and 12-month courses of NanoCelle® THC/CBD oral buccal spray, approximately 50% had muscular or neuropathic pain; 32% had soft tissue pain with muscular pain; 11% had visceral pain; and 7% registered “other categorised pain”.

Safety and tolerability

  • The results support the safety and tolerability of NanoCelle® THC/CBD oral buccal spray for pain in a chronically ill cohort of patients with intractable pain. Furthermore, the study presented preliminary analgesic efficacy of NanoCelle® THC/CBD oral buccal spray for pain management in a real world setting while remains consistent with the growing body of evidence supporting the drug

^ Results are relative to the 55% of participants that had been tracked as of today’s date.
