Background: The prospective observational MObility ImproVEment (MOVE) 2 study is collecting real-life clinical outcomes data on patients with treatment-resistant multiple sclerosis (MS) spasticity treated with THC:CBD oromucosal spray in routine clinical practice. The MOVE 2 study has been ongoing in Italy, involving more than 30 MS centres across the country, since 2013. Methods: Web-based real-time data collection techniques are combined with traditional patients’ diaries to capture a wide spectrum of outcomes associated with this innovative cannabis-based medication. After surpassing the recruitment threshold of 300 patients, an interim analysis was performed to determine whether the data collected to date align with those from MOVE 2-Germany and the largest phase III randomized controlled trial (RCT) of THC:CBD oromucosal spray. Results: In the Italian cohort, THC:CBD oromucosal spray was added mainly to oral baclofen. Similar to MOVE 2-Germany, during 3 months’ observation, treatment discontinuations were limited and patients recorded meaningful improvements on the patient-based 0–10 numerical rating scale and physician-rated modified Ashworth scale at mean daily doses that were about one-third lower than those used in the RCT. Also, similar to MOVE
2-Germany, the proportion of patients reporting adverse
events was about one-third of the rate recorded in the RCT.
Conclusions: While MOVE 2-Italy continues, this interim
analysis has enabled us to better define the place in therapy
of THC:CBD oromucosal spray within the context of daily
management of our patients with MS spasticity.
