Clinical trial: Evaluating the Effectiveness of Escitalopram in Preventing or Reducing Depressive Symptoms in People Receiving Interleukin-2 Treatment

Summary: This study will determine the effectiveness of an antidepressant in preventing or reducing depressive symptoms in people with melanoma who are receiving Interleukin-2 (IL-2) treatment.

Detailed description: Melanoma is the most serious type of skin cancer, affecting nearly 54,000 people in the United States each year. Melanomas often develop in pre-existing moles or as new moles on the body. If left untreated, the cancerous cells can spread throughout the body. Fortunately, melanoma can be cured if a person is diagnosed and treated early. Typical treatments include surgery, amputation, chemotherapy, and immunotherapy. Interleukin-2 (IL-2) treatment, a type of immunotherapy, uses the body's immune system to slow or stop the spread of cancer cells to other parts of the body. However, IL-2 treatment is typically associated with severe side effects, including depression, fatigue, and difficulty thinking. This study will evaluate whether escitalopram, an antidepressant, can help improve treatment-related depressive symptoms, reduce stress hormone levels, and increase the number of treatment cycles among people with metastatic melanoma who are receiving IL-2 treatment.
  Participation in this double-blind study will last up to 18 weeks and will include 5 to 14 study visits. Participants will complete four 1-week cycles of IL-2 treatment over a 12-week period. Two weeks prior to starting IL-2 treatment, participants will undergo a psychiatric interview; a computerized thinking test; questionnaires; and blood, urine, and saliva collection. Participants will also be randomly assigned to start receiving either escitalopram or placebo for the entire duration of the study. The dosage of escitalopram or placebo will vary depending on the symptom severity of each participant. Immediately prior to IL-2 treatment, participants will undergo preliminary IL-2 procedures, which will include a medical history review, physical exam, and blood collection. These same procedures will occur every day that the participant is in the hospital for IL-2 treatment. Participants will stay in the hospital when receiving all four IL-2 treatment cycles. During these hospital stays, participants will complete repeat questionnaires and computerized tasks. Blood collection will occur at selected times as well. A follow-up visit will occur 4 weeks after the final treatment dose of IL-2.
