Pharmacogenomic Testing to Personalize Supportive Oncology

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate pharmacogenomics (PGx) guided drug prescribing for pain and depression in patients with cancer. The investigators aim to understand how PGx testing can be used to improve medication management for pain and depression, and whether PGx-guided prescribing improves these symptoms and quality of life compared to historical controls.

Detailed Description
-----------------
This is a prospective clinical trial of adult cancer patients presenting with pain and depression, newly referred to the Department of Supportive Oncology, and receiving preemptive PGx testing for genes related to supportive care prior to the first clinic visit. Genotyping results will be returned within approximately 4-5 business days. A PGx specialist will provide detailed clinical interpretations to the referring provider and upload a copy of the test results into the subject's medical chart. A consultation note will also be placed in each subject's chart detailing the PGx results. Supportive Oncology clinicians will be instructed to consult a pharmacist to evaluate PGx test results prior to prescribing supportive care therapies, especially pain and depression medications. The number of consults and recommendations will be documented, in addition to test results, demographic data, medical/medication history, ESAS symptom scores, PHQ9 depression scores, and side effects of supportive therapy. The number of ambulatory clinic visits and hospitalizations will be used to estimate health care utilization and costs. Subjects will complete a short survey at the end of the study period regarding their knowledge about PGx, and whether access to PGx information improves satisfaction with care and communication.

Eligibility Criteria
-----------------
Inclusion Criteria Written informed consent and HIPAA authorization for release of personal health information. Completion of ESAS at initial palliative medicine clinic visit, presenting with moderate to high pain (≥ 4/10) and/or depression (≥ 3/10). New patients ≥ 18 years of age who have had an initial visit in the Department of Supportive Oncology's palliative medicine clinic with hematologic malignancy or any stage solid tumor malignancy according to the provider. Agree to at least one additional palliative medicine clinic visit per protocol. Able to provide a buccal sample for PGx testing. Exclusion Criteria Psychiatric illness, social situations, or active/recent (within 30 days) history of illicit substance (e.g. cocaine, heroin) abuse that would limit compliance with study requirements (e.g. clinic visits, medication compliance, etc.) as determined by the Investigator. Patients who have had prior multiple visits in palliative medicine clinic.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Utilization of PGx results | Estimate the proportions of subjects undergoing PGx testing who receive at least one drug/dose selection or modification based on PGx test results within any of the study visits after the Baseline study visit. | 21, 42, 63 and 84 days after the baseline visit | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain Scores Impact | Determine the impact of PGx on treatment outcomes by measuring pain scores on a scale of 0-10 (0 no pain, 10 worst possible severity) using the Edmonton Symptom Assessment Scale (ESAS) at study visits after the Baseline study visit. Symptom scores will also be compared between those receiving PGx testing and a matched control receiving clinical management alone. | 21, 42, 63 and 84 days after the baseline visit | 
| Depression Scores Impact | Determine the impact of PGx on treatment outcomes by measuring depression on a scale of 0-27 (0 no depression, 27 severe depression) using the Patient Health Questionnaire 9 (PHQ9) at study visits after the Baseline study visit. Symptom scores will also be compared between those receiving PGx testing and a matched control receiving clinical management alone. | 21, 42, 63 and 84 days after the baseline visit | 
| Compare Health Care Utilization | Compare health care utilization (HCRU) using cost in USD, including but not limited to cost associated with inpatient, emergency department, outpatient, and pharmacy encounters between subjects receiving PGx testing and matched controls receiving clinical management alone. | 84 days | 
| Subject Perspectives | Describe subject perspectives of PGx testing using a survey administered to subjects after/at the Final visit (or sooner if withdrawn). | Assessed at the final study visit (day 84) |
