Malignancy
YES
The aim of this study is to explore the interindividual variability in pharmacokinetics, clinical effects on sleep-related symptoms, and tolerability of orexin receptor antagonists in patients with cancer, focusing on cancer cachexia, inflammatory cytokines, CYP3A activity, genetic polymorphisms, and concomitant medications.
Pharmacokinetics
Others
Not applicable
Plasma concentrations of orexin receptor antagonists on day 7 or later after initiation of treatment
1. Sleep-related symptoms, including nocturnal awakenings and daytime sleepiness
2. Genotyping, including CYP3A5
3. CYP3A activity marker, including 4beta-hydroxycholesterol
4. Cancer cachexia status assessed by EPCRC classification and Glasgow Prognostic Score
5. Inflammatory cytokines and inflammatory/nutritional markers, including IL-6, CRP, albumin, and total cholesterol
6. Effects of concomitant medications
7. Adverse reactions, including somnolence, dizziness, falls, and other clinically relevant symptoms
Observational
| 18 | years-old | <= |
| Not applicable |
Male and Female
1. Patients aged 18 years or older with a confirmed diagnosis of solid cancer
2. Patients treated with orexin receptor antagonists
3. Patients treated in the outpatient or inpatient setting at Shinshu University Hospital
4. Patients from whom written informed consent was obtained
1. Patients using orexin receptor antagonists on an as-needed basis
2. Patients considered not to have reached steady-state plasma concentrations of orexin receptor antagonists
3. Patients who have undergone hematopoietic stem cell transplantation
4. Patients judged by the principal investigator to be inappropriate for the study
