Chemotherapy, Genotyping, Supportive Care
Conditions
Brief summary
Cancer patients often require administration of multiple supportive care pharmacotherapies while receiving chemotherapy regardless the type of cancer. Supportive care therapies are commonly prescribed to nearly all cancer patients and could include antiemetics (ondansetron), pain management (opiates), GI protection (PPIs), antidepressants (select SSRIs), anticoagulation (warfarin) and antifungal prophylaxis (voriconazole). These are all are associated with known pharmacogenetic interactions, which in some cases render the drugs ineffective or toxic. This could result in negative impacts on quality of life in patients who are already undergoing complicated and costly anticancer regimens. Pharmacogenetic-guided therapy based on an individual patient's genetic profile could potentially target symptoms for which an individual is uniquely susceptible, guiding use of medications that are most likely to be effective, thereby reducing unnecessary physical complications and financial strain. It is hypothesized that patients in the genotype intervention arm will report lower scores for overall symptom distress as compared to patients in the delayed genotype intervention arm following initiation of chemotherapy.
Detailed description
This is a single center, pilot randomized pragmatic clinical trial (PCT) of 500 cancer patients who are undergoing chemotherapy for newly diagnosed or recurrent cancers. Patients will be randomized to genotyping intervention vs delayed genotyping intervention supportive care. Supportive care regimens may include therapies for antiemesis (ondansetron), pain management (opiates), GI protection (PPIs), antidepressants (select SSRIs), and antifungal prophylaxis (voriconazole), and warfarin depending on their chemotherapy regimen. For those randomized to the genotype intervention group, genotype results will be returned in the EHR pre-emptively and supportive care will be prescribed based on genotype results. For those randomized to the delayed genotype intervention group, supportive care will be prescribed based on usual clinical practice. Both groups will be followed for 3 months and undergo assessments with the MDASI questionnaire four times (pre-chemotherapy, and 2 weeks, 4 weeks and 12 weeks post initiation of chemotherapy. Records for patients receiving outpatient care at the UF Health Cancer Center clinic at the Medical Plaza will be screened based on inclusion / exclusion criteria for participation in this study. Those that meet criteria will be offered participation. Participation is expected to last approximately 12 weeks and the study will be open for 30-36 months.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in patient MDASI scoring | At pre-chemotherapy (baseline), 2 weeks, 4 weeks, and 12 weeks post initiation of chemotherapy. | The M. D. Anderson Symptom Inventory (MDASI) is a multisymptom patient-reported outcome measure. Participants are asked to recall symptom interference and severity during the past 24 hours and rate the symptom using a numeric rating scale, 0-10. For the symptom interference questions, 10 means interfered completely and 0 is did not interfere. For the symptom severity questions, 10 means as bad as you can imagine and 0 is not present. The MDASI questionnaire will evaluate symptom distress and core symptoms of patients at four separate time points. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in patient medication use | At pre-chemotherapy (baseline), 2 weeks, 4 weeks, and 12 weeks post initiation of chemotherapy. | Concomitant Medication Review will be collected from patients or from their electronic medical record to evaluate differences in medication use (drug and dose) based on randomized group. |
