Can a sleep therapy and melatonin combo help older adults beat chronic insomnia?
NCT ID NCT07695246
First seen Jul 10, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This study tests whether adding melatonin to cognitive behavioural therapy for insomnia (CBT-I) improves sleep in adults aged 60 and older with chronic insomnia. Participants are randomly assigned to receive CBT-I plus melatonin, CBT-I plus a placebo, or sleep education plus a placebo, all over four weekly group sessions. The goal is to see if the combination reduces insomnia symptoms more than CBT-I alone or education alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Melatonin 3 mg immediate-release
- What this could lead to
- If successful, this could point toward a combined behavioural and medication approach to improve sleep in older adults without long-term drug dependence.
- What could go wrong
- This is a relatively small, early-stage trial, and the effects of melatonin added to CBT-I may be modest. Results may not apply to all older adults or those with other health conditions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Chinese aged ≥ 60. 2. Provision of written informed consent. 3. Having a DSM-5 diagnosis of insomnia disorder (i.e., having difficulty initiating sleep, maintaining sleep, or early morning awakening at least three times a week for at least three months, with clinically significant impairment or distress). 4. Having a score of \> 14 on the ISI, indicating clinical insomnia. Exclusion Criteria: 1. Having a current diagnosis or a history of manic or hypomanic episodes, schizophrenia spectrum disorders, neurodevelopmental disorders, neurocognitive disorders, organic mental disorders, intellectual disabilities, or substance abuse or dependence. 2. Having a progressive medical condition directly related to the onset and course of insomnia (e.g., cancer, chronic pain). 3. Undergoing treatment for diseases known to affect sleep (e.g., chemotherapy). 4. Having an untreated sleep disorder that may disrupt sleep continuity and quality (e.g., sleep-disordered breathing) except for insomnia disorder. 5. Having mild to significant cognitive impairment, defined by having a score of \< 22 on MOCA. 6. Concurrent and regular use of extraneous melatonin or melatonin agonist (e.g., ramelteon). 7. Receiving concurrent psychological treatment for insomnia. 8. Meeting potential contraindications for melatonin (e.g., undergoing dialysis) or concurrently using medications that have a potential drug interaction with melatonin (e.g., anticoagulant and anti-platelet). 9.
