This study is for patients that have been diagnosed with Merkel cell carcinoma. The investigational drug in this study is pembrolizumab. This study will compare any good and bad effects of using radiation along with an immunotherapy treatment [MK-3475 (pembrolizumab)] compared with MK-3475 (pembrolizumab) alone. Participants can expect to be in this study for up to 7 years.
This research study is for patients who have completed all scheduled surgery, chemotherapy and/or radiation therapy for their cancer within the last 6-12 months and are currently having some type of sleep disturbance. While there is no standard treatment for sleep disturbance for cancer survivors, people who do not take part in this study may take over-the-counter or prescription medications, receive cognitive behavioral therapy, or exercise as a means of attempting to manage their sleep problems.
Sleep disturbance, particularly insomnia, is a common problem for cancer survivors. Insomnia can be described as excessive daytime napping, difficulty falling asleep, difficulty staying asleep, or waking up earlier than you would like. Insomnia can increase fatigue, impair physical function, impair immune function, cause circadian rhythms (known as your biological clock) to be disrupted and decrease quality of life.
Because there is no ideal standard of care for effectively treating sleep problems in cancer survivors, the purpose of this study is to compare the effectiveness of three different treatments for improving sleep problems and determine which is best. The three treatments are yoga, survivorship health education, and cognitive behavioral therapy (CBT-I).
Study participation will be approximately 8 months.
