Study Overview
Brief Summary
Clinical study GWCA0999 is a six month, Phase III, non-comparative, follow-on study to evaluate the safety of long-term Sativex therapy in patients with advanced cancer.
Primary Objective is to evaluate the safety of long-term Sativex therapy when used as an adjunctive (not breakthrough) measure in patients with advanced cancer.

Secondary Objectives are to assess the maintenance of effect through long-term usage of Sativex as adjunctive therapy for the relief of uncontrolled persistent chronic cancer related pain.
In xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" /India thousands of cases related to cancer pain are reported every year. This molecule has been studied previously and there are no concerns with respect to the safety profile of the molecule. The conduct of this study in India will help generate data on ’safety’ & ’maintenance of effect’ of Sativex. The data will support the use of Sativex oromucosal spray (Sativex®; Nabiximols) as adjunctive therapy in relieving uncontrolled persistent chronic pain in patients with advanced cancer who have inadequate analgesia even with optimized chronic opioid therapy.
This trial is likely to benefit about 65 patients that will participate in the study and further may provide a new treatment to patients with cancer pain if the molecule is found to be successful.

Exclusion Criteria
- •The patient is currently using cannabis or cannabinoid based medications, other than the parent study IMP, and is unwilling to abstain for the duration of the study
- •Any history or immediate family history of schizophrenia, other psychotic illness, severe personality disorder or other significant psychiatric disorder other than depression associated with their underlying condition
- •Any known or suspected history of a substance abuse/dependence disorder (including opiate abuse/dependence prior to the diagnosis of cancer)
- •Has poorly controlled epilepsy or recurrent seizures (i.e. one or more seizure during the last year)
