Brief summary

The purpose of this study is to determine whether a consultation with a Personalized Therapeutics Clinic, or PTC, will help participants lower the risk for side effects (drug-drug interactions and drug-gene interactions) when taking many medications and help providers improve prescribing decisions for participants. A PTC is a clinical that will test your genes to gather information about your health that may help guide prescribing advice and offer you new information about your prescriptions. Doctors leading this study will look for variations (differences) in your genes that may suggest that you are at greater risk of having side effects or a greater chance of benefiting from certain medications. Individuals in this study will participate for roughly 9 months.

Interventions

OTHERDrug-Drug Interaction Profile

A profile based on genetic testing that shows information about how the participant's medications they are taking interact with each other.

OTHERDrug-Gene Interaction Profile

A profile based on genetic testing that shows information about how the participant's genes interact with/respond to certain medications they are taking.

OTHERStandard of Care

The standard treatment and prescribing for the participant's specific type of cancer.

Design outcomes

Primary

MeasureTime frameDescription
Change in Rate of Drug-Drug Interactions and Drug-Gene Interactions Among Participants9 monthsThe change in the composite rate of drug-drug interactions (DDIs) and drug-gene interactions (DGIs) from baseline (at beginning of study) and after each intervention compared between all three arms.

Secondary

MeasureTime frameDescription
Participants At High-Risk for Drug-Drug and Drug-Gene Interactions9 monthsReported as a percentage of total hospitalized participants
Strategy to Implement at Personalize Therapeutic Clinic (PTC) at Specific Sites Based on Available Mediators (PTC Partners)9 monthsAn implementation strategy for a site-specific Personalized Therapeutic Clinic (PTC) as assessed by evaluating which mediators and moderators who may be able to adopt PTC recommendations.
Rate of Hospitalizations9 monthsThe rate of hospitalizations among participants in all three arms as assessed by study notes/clinical record.
Rate of Emergency Department Visits9 monthsRate of emergency department visits among participants in all three arms as assessed by study notes/clinical record.
Rate of Reported Adverse Events as Assessed by Clinical Records9 monthsRate of reported adverse drug events among participants in all three arms as assessed by study notes/clinical record.
Changes in Participant Knowledge and Perceptions of the Personalized Therapeutic Clinic (PTC) as Assessed by Survey Results9 monthsChanges in participant knowledge and perceptions of the PTC will be assessed using surveys administered at baseline and after the first post-PTC visit with their primary treating provider.
Changes in provider knowledge and perceptions of the Personalized Therapeutic Clinics (PTC) Assessed by Survey Results9 monthsChanges in provider knowledge and perceptions of the PTC as assessed by survey collected from providers at baseline and at the end of study.
