Single-Dose Subcutaneous Benzodiazepines for Insomnia in Patients With Advanced Cancer

Zopiclone versus placebo for short-term treatment of insomnia in patients with advanced cancer-a double-blind, randomized placebo-controlled clinical multicenter phase IV trial

PURPOSE

Insomnia is frequent in patients with advanced cancer, and a variety of pharmacological agents is used to treat this condition. Still, few clinical trials have investigated the effectiveness of pharmacological sleep therapies in this patient group. We aimed to study the short-term effectiveness of zopiclone on sleep quality in patients with advanced cancer who report insomnia.

METHODS

A randomized, double-blind, placebo-controlled, parallel-group, multicenter, phase IV clinical trial in adult patients with metastatic malignant disease and insomnia. Patients were treated with zopiclone or placebo for six subsequent nights. Primary end point was patient-reported sleep quality during the final study night (NRS 0-10). Secondary end points were patient-reported sleep onset latency (SOL) and total sleep time (TST).

RESULTS

Forty-one patients were randomized, with 18 being analyzed in the zopiclone group and 21 in the placebo group. Median age was 66, median Karnofsky performance score was 80, and 56% were male. Mean sleep quality at end of study was 2.9 (CI 2.3 to 3.8) in the zopiclone group and 4.5 (CI 3.6 to 5.4) in the placebo group (p = 0.021). At end of study, SOL was significantly different between the treatment groups: zopiclone 29 min (CI 13 to 51) and placebo 62 min (CI 40 to 87) (p = 0.045). TST was not significantly different across groups: zopiclone 449 min (403 to 496) and placebo 411 min (CI 380 to 440) (p = 0.167).

CONCLUSION

Zopiclone improved short-term patient-reported sleep quality in this cohort of patients with advanced cancer.

Effect of Two Interventions on Sleep Quality for Adolescent and Young Adult Cancer Survivors: A Pilot Randomized Controlled Trial

BACKGROUND

Sleep disturbance is common among adolescent and young adult (AYA) cancer survivors. Physical activity (PA) and behavioral activation (BA) therapy have been reported as enhancing sleep quality, but few studies exist on the effects of such interventions combined with technology to promote sleep quality in AYA cancer patients.

OBJECTIVE

The aim of this study was to investigate the feasibility and effects of intelligent wearable device-based PA therapy and internet-based modified BA therapy to improve sleep quality among AYA cancer patients.

METHODS

A randomized controlled trial with 143 AYA cancer patients was conducted. Participants were randomly assigned to a control group (n = 48), which performed routine care, a PA group (n = 47), which received 8-week PA therapy based on intelligent wearable devices, and a BA group (n = 48), which participated in internet-based modified BA therapy for 8 weeks.

RESULTS

At 1 week and 3 months after the intervention for sleep quality, there were statistically significant differences between the PA group and the control group (P = .020), but no statistically significant difference between the BA group and the control group.

CONCLUSIONS

The intelligent wearable device-based PA therapy has more advantages than internet-based modified BA therapy in improving the overall state of AYA cancer patients, and the intervention effect was sustained for at least 3 months.

IMPLICATIONS FOR PRACTICE

Developing and implementing PA plans for AYA cancer survivors can improve their sleep quality. Social media, intelligent wearable devices, and mobile health applications have unique advantages in promoting sleep quality for AYA cancer survivors.

Midazolam: an essential palliative care drug

Midazolam is a commonly used benzodiazepine in palliative care and is considered one of the four essential drugs needed for the promotion of quality care in dying patients. Acting on the benzodiazepine receptor, it promotes the action of gamma-aminobutyric acid. Gamma-aminobutyric acid action promotes sedative, anxiolytic, and anticonvulsant properties. Midazolam has a faster onset and shorter duration of action than other benzodiazepines such as diazepam and lorazepam lending itself to greater flexibility in dosing than other benzodiazepines. The kidneys excrete midazolam and its active metabolite. Metabolism occurs in the liver by the P450 system. This article examines the pharmacology, pharmacodynamics, and clinical uses of midazolam in palliative care.

Zopiclone versus placebo for short-term treatment of insomnia in patients with advanced cancer: study protocol for a double-blind, randomized, placebo-controlled, clinical multicenter trial

BACKGROUND

Despite the high prevalence of insomnia in patients with advanced cancer, there are no randomized controlled trials on pharmacological interventions for insomnia in this group of patients. A variety of pharmacological agents is recommended to manage sleep disturbance for insomnia in the general population, but their efficacy and safety in adults with advanced cancer are not established. Thus, there is a need to evaluate the effectiveness of medications for insomnia in order to improve the evidence in patients with advanced cancer. One of the most used sleep medications at present in patients with cancer is zopiclone.

METHODS

This is a randomized, double-blind, placebo-controlled, parallel-group, multicenter trial. A total of 100 patients with metastatic cancer who report insomnia will be randomly allocated to zopiclone or placebo. The treatment duration with zopiclone/placebo is 6 consecutive nights. The primary endpoint is patient-reported sleep quality during the final study night (night 6) assessed on a numerical rating scale of 0-10, where 0 = Best sleep and 10 = Worst possible sleep. Secondary endpoints include the mean patient-reported total sleep time and sleep onset latency during the final study night (night 6).

DISCUSSION

Results from this study on treatment of insomnia in advanced cancer will contribute to clinical decision-making and improve the treatment of sleep disturbance in this patient cohort.
