Trial Outcomes & Findings for Sativex® for Relieving Persistent Pain in Participants With Advanced Cancer (NCT NCT01262651)

NCT ID: NCT01262651

Last Updated: 2018-04-23

Results Overview

Participants indicated level of pain in the last 24 hours on an 11-point Numerical Rating Scale (NRS), where a score of 0 was "no pain" and 10 was "pain as bad as you can imagine". Baseline = mean score from first day of 3-day eligibility period through to the day before first dose of study drug. End of Treatment = mean score over last (up to) 7 days to the final pain score at End of Treatment or up until Day 35, whichever is earlier, or final score available (prematurely terminated). Percentage improvement from baseline (Imp%) was calculated as: Imp% = (Baseline pain NRS mean - End of Treatment pain NRS mean)/Baseline pain NRS mean \* 100. For participants who died or withdrew due to disease progression, Imp% values were used. For participants who died or withdrew unrelated to disease progression before end of Week 5 (no diary data from Day 33 onwards), Imp% was zero for participants whose Imp% value was positive and it was Imp% for participants whose Imp% value was not positive.

Participant Flow

Per the Statistical Analyses Plan, all randomized participants who received at least 1 dose of study drug were analyzed in the Intent-to-Treat (ITT) population as per randomized treatment group. However, if a participant randomized to placebo ever took a nabiximols dose, the participant was analyzed as nabiximols-treated in the Safety population.

Measure
Nabiximols
Nabiximols was self-administered by participants as a 100 microliter (μL) oromucosal spray in the morning and evening, up to a maximum of 10 sprays per day, for 5 weeks. Nabiximols oromucosal spray contained delta-9-tetrahydrocannabinol (THC) (27 milligram \[mg\]/milliliter \[mL\]):cannabidiol (CBD) (25 mg/mL), in ethanol:propylene glycol (50:50) excipients, with peppermint oil (0.05%) flavoring. Each 100 μL actuation delivered 2.7 mg THC and 2.5 mg CBD.
Placebo (GA-0034)
Placebo was self-administered by participants as a 100 μL oromucosal spray in the morning and evening, up to a maximum of 10 sprays per day, for 5 weeks. Placebo oromucosal spray contained ethanol: propylene glycol (50:50) excipients, with peppermint oil (0.05%) flavoring and colorings.

PRIMARY outcome

Timeframe: Baseline, End of Treatment (Day 36)

Population: The ITT Population included all participants who were randomized, received at least 1 dose of study drug, and had at least 1 efficacy endpoint. Participants were analyzed according to the treatment group they were randomized to.

Participants indicated level of pain in the last 24 hours on an 11-point Numerical Rating Scale (NRS), where a score of 0 was "no pain" and 10 was "pain as bad as you can imagine". Baseline = mean score from first day of 3-day eligibility period through to the day before first dose of study drug. End of Treatment = mean score over last (up to) 7 days to the final pain score at End of Treatment or up until Day 35, whichever is earlier, or final score available (prematurely terminated). Percentage improvement from baseline (Imp%) was calculated as: Imp% = (Baseline pain NRS mean - End of Treatment pain NRS mean)/Baseline pain NRS mean \* 100. For participants who died or withdrew due to disease progression, Imp% values were used. For participants who died or withdrew unrelated to disease progression before end of Week 5 (no diary data from Day 33 onwards), Imp% was zero for participants whose Imp% value was positive and it was Imp% for participants whose Imp% value was not positive.

The total daily opioid use (in morphine equivalence) was the sum of morphine equivalents of daily maintenance dose and break-through dose. Change in daily total opioid use was calculated as: End of Treatment daily total opioid use - Baseline daily total opioid use. A negative value indicates a decrease in use from Baseline.

The prescribed daily quantity of opioid maintenance dose was calculated as the product of dose per use and daily frequency of use. Participants were asked: "Have you used your maintenance dose painkiller today as prescribed?" If the participant answered "No" to the question, the daily opioid maintenance dose usage on that day was set to 0. Change in daily maintenance opioid dose was calculated as: End of Treatment daily maintenance opioid dose - Baseline daily maintenance opioid dose. A negative value indicates a decrease in dose from Baseline.
