About this study

Official title: Genomic Medicine Pilot for Hypertension and Kidney Disease in Primary Care

In this genomic medicine implementation pilot project, the investigators aim to conduct a randomized trial in a network of community health centers and primary care facilities to study processes, effects and challenges of incorporating information for apolipoprotein L1 (APOL1)-attributable genetic risk for end stage kidney disease in patients of African ancestry with hypertension .

Read the detailed description

CKD is most commonly associated with diabetes (40%) and hypertension (28%), and affects 26 million American adults. African ancestry populations with hypertension (HTN) have 2- to 3-fold higher risk of developing CKD, and a 5-fold increased risk to progress to end stage renal disease (ESRD) when compared with whites. HTN is a risk factor for progression of CKD and for increased cardiovascular risk with CKD. Thus targeting blood pressure control as a modifiable risk factor may both reduce CVD in people with CKD and reduce progression of CKD to end stage disease. Recent discoveries demonstrate that testable alleles of the APOL1 locus on chromosome 22 have a major effect on and explain almost all of the excess risk for hypertension-associated CKD and its progression to ESRD in African ancestry populations.

We will use community-engaged approaches to enroll patients of African Ancestry with HTN from a network of community health centers and primary care facilities in Harlem and the Bronx and randomize them on a 7 to 1 ratio to receive APOL1 genetic testing and EMR-enabled provider clinical decision support incorporating APOL1 genomic risk information.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Immediate Genetic TestingOther

    Also called Genetic Risk Communication

    Participants will receive the APOL1 genetic test. Trained research staff will meet with participants to communicate results and lifetime ESRD risk attributable to variations in the APOL1 gene. Primary care providers will receive APOL1 genetic risk information via a best practice alert in the participant's EMR upon commencement of a patient encounter and through results filed in the participant's genetics results section of their EMR.

Control- Delayed TestingNo interventionParticipants randomized to control will not receive the APOL1 genetic test upon study enrollment. They will be offered the option to take the test during their final follow-up study visit (12 months post enrollment).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Urine Protein Excretion

    Number of participants with urine protein excretion in urine tests to assess kidney function at 12 months as compared to baseline

    Measured: Baseline and 12 months

  2. Change in Systolic Blood Pressure

    Change in systolic blood pressure at 3 months as compared to baseline

    Measured: Baseline and 3 months

Secondary outcomes (3)
  1. Number of Participants With Change in Medication Adherence

    Participant surveys (self-report) regarding medication adherence behaviors 3 months after randomization

    Measured: 3 months

  2. Number of Patients With Changes in Psychosocial Behaviors

    Number of patients with changes in psychosocial behaviors 3 months after randomization

    Measured: 3 months

  3. Number of Participants With Attitude Towards Genetic Testing

    Patient attitude towards genetic testing 3 months after randomization

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A study testing Immediate Genetic Testing in people with Hypertension and Chronic Kidney Disease, run by Icahn School of Medicine at Mount Sinai at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Oct 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Urine Protein Excretion (time frame: Baseline and 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02234063, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Oct 2020.
