Effect of Ketamine on Fatigue Following Cancer Therapy

• Status: Terminated
• Trial end date: 2019-03-18
• Target enrollment: 0
• Participant gender: All

Summary

Background:

• Fatigue is a common side effect of cancer and its treatment. No medications can treat this fatigue. Researchers want to see if the drug ketamine can improve fatigue after radiation therapy for cancer. They will compare the effects of ketamine on fatigue to midazolam, a sedative with similar effects.

Objectives:

• To better understand fatigue in people who completed radiation therapy for cancer. To look at the effects of a dose of ketamine on fatigue.

Eligibility:

• Adults 18 and older who completed radiation therapy for cancer and are enrolled in NIH protocol 08-NR-0132.

Design:

• Participants will be screened with medical history, physical exam, and blood and urine tests. They will complete questionnaires about their fatigue and take a breath alcohol test.

• The study is divided into 2 phases:

• During the first phase I visit, participants will have blood taken. They will talk about their fatigue and other symptoms. They will take thinking and handgrip strength tests. Then they will get either ketamine or placebo (midazolam) through an intravenous line, placed by a needle guided by a thin plastic tube into an arm vein.

• Participants will have a follow-up phone call within 1 day.

• Participants will have phase I visits 3, 7, and 14 days after infusion. For the 3- and 7-day visits, participants will take thinking and handgrip strength tests. They will complete questionnaires, talk about infusion side effects, and have blood taken. For the 14-day visit, they will talk about their fatigue and infusion side effects. They will start phase II that day.

• Phase II visits are the same as phase I, except that the 14-day visit is over the phone.

• Phase: Early Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: National Institute of Nursing Research (NINR)
• Treatments: Ketamine; Midazolam

Criteria

• INCLUSION CRITERIA:

• Must be enrolled in 08-NR-0132.

• Had cancer as determined by diagnostic testing such as cytology and imaging and confirmed from the oncologist s progress notes or reference letter;

• At least 3 months following localized radiation therapy (e.g. intensity-modulated radiation therapy) for cancer;

• Total received radiation dose is 40-80 Gray (Gy);

• Able to provide written informed consent and must exhibit understanding of the study during the informed consent process by passing at least 80% of the consent quiz;

• Greater than or equal to18 years of age;

• FACT-F score should be <43, to reflect that the study subjects fatigue symptoms are worse than the general population (Cella et al., 2002).

In addition to the above inclusion criteria, in order to receive the study drug (ketamine or placebo), the subject must have the following during the randomization visit:

-No clinically significant abnormal laboratory tests (i.e. absolute neutrophil count <1.5 thousand (K) cells/(micro)L, platelet <75K cells/(micro)L, hemoglobin <9 grams per deciliter (g/dL).

EXCLUSION CRITERIA:

• Progressive or unstable disease other than cancer of any body system causing clinically significant fatigue (e.g. class IV congestive heart failure, end-stage renal disease, liver failure, stage IV chronic obstructive pulmonary disease) including patients with systemic infections (e.g., human immunodeficiency virus (HIV), active hepatitis); and those with chronic inflammatory disease (e.g. rheumatoid arthritis, systemic lupus erythematosus);

• Uncontrolled hypertension and those with left ventricular dysfunction;

• Current psychotic features or a diagnosis of Schizophrenia or any other psychotic disorder as defined in the Diagnostic and Statistical Manual (DSM-IV);

• Subjects with a history of DSM-IV drug or alcohol dependency or abuse (except for caffeine or nicotine dependence) within the preceding 3 months. In addition, subjects who currently are using illicit drugs (except for caffeine or nicotine) must not have used illicit substances in the 2 weeks prior to screen and must have a negative alcohol and drug (except for prescribed benzodiazepines) breathalyzer and urine test at screening, respectively;

• Subjects with clinical hypothyroidism or hyperthyroidism;

• Subjects with one or more seizures, hallucinations, disorientation without a clear and resolved etiology;

• Subjects with traumatic brain injury and/or post-traumatic stress disorder;

• Treatment with a reversible monoamine oxidase inhibitor (MAOI) within two weeks prior to study drug administration;

• Treatment with fluoxetine within five weeks or aripiprazole within three weeks before study drug administration;

• Treatment with any other concomitant medication known to interact with ketamine 14 days prior to study drug administration.

• Received total body irradiation or cranial irradiation for cancer;

• Pregnant or lactating women.
