Clinical Trial Summary

The overall goal of the study is to improve equitable delivery of pre-Tumor genetic testing (TGT) counseling tool for Black or African American men with metastatic prostate cancer and evaluating the tool for implementation.

Description:

PRIMARY OBJECTIVES:

Stage 1: To evaluate education quality of the intervention in Black or African American men with prostate cancer.

Stage 2: To evaluate feasibility of the TGT intervention among Black or African American men with prostate cancer

SECONDARY OBJECTIVES:

Stage 1:

1. To evaluate completeness of the intervention content.

2. To identify barriers and facilitators for using the intervention.

Stage 2:

1. To evaluate the acceptability of the intervention among Black or African American men with prostate cancer.

2. To evaluate change in participant knowledge about tumor genetic testing among Black or African American men with prostate cancer.

3. To evaluate change in patient attitudes toward tumor genetic testing among Black or African American men with prostate cancer.

4. To evaluate change in participant expectations of tumor genetic testing among Black or African American men with prostate cancer.

5. To evaluate patient perspectives on the intervention.

6. To evaluate the rate of TGT among Black or African American men with prostate cancer who have received the tumor genetic pre-test counseling tool.

OUTLINE:

This is a two-stage study. In Stage 1, Adult Black or African American men with metastatic prostate cancer who have not made a decision about TGT, or who have decided to undergo TGT, or patients who have decline TGT about tumor genetic testing will participate in development by answering questionnaires and utilizing the pilot application for up to 60 days. The investigators will then refine the tool to be piloted in Stage 2.

Stage 2: A pilot study of participants who are planning to have a discussion about undergoing tumor genetic testing with their oncology provider will be invited to join and utilize the tool, and answer questionnaires about the tool.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Frequency of participant responses (Stage 1)	Participant-reported perspectives of intervention in a semi-structured interview will be collected during Stage 1 and reviewed and will be explored using thematic analysis. A codebook will be created using the PEMAT (for the primary objective) described in the interview guide. This framework provides a systematic approach for identifying behavior change models evaluated according to three criteria: comprehensiveness, coherence, and a clear link to an overarching model of behavior. This will produce evidence-based behavior change techniques most likely to be effective. Emergent codes and themes will be added throughout thematic analysis. Two coders will code each interview (one primary and one secondary coder). Discrepancies will be negotiated to consensus.	1 day
Primary	Proportion of enrolled participants (Stage 2)	The proportion of participants who enrolled in the study after being approached by their healthcare team will be reported.	1 day
Primary	Proportion of enrolled participants who review all educational materials (Stage 2)	The proportion of all enrolled participants who utilized and reviewed all of the educational materials in the tool will be reported.	Up to 60 days
Primary	Mean score of Feasibility of Intervention Measure (FIM) (Stage 2)	Scores on the FIM will be averaged across all participants. Items will be scored on a 5-point scale: 1= Completely disagree, 2 = Disagree, 3 = Neither agree nor disagree, 4 = Agree, 5= Completely agree. A higher mean score indicates greater feasibility. The mean score and standard deviation will be reported.	Up to 60 days
Secondary	Mean score of Acceptability of Intervention Measure (AIM) (Stage 2)	Scores on the AIM items will be averaged across all participants. Items will be scored on a 5-point scale: 1= Completely disagree, 2 = Disagree, 3 = Neither agree nor disagree, 4 = Agree, 5= Completely agree. A higher mean score indicates greater feasibility. The mean score and standard deviation will be reported.	Up to 60 days
Secondary	Mean score of investigator-developed, measure of acceptability items (Stage 2)	Scores on the 5-item investigator-developed, measure of acceptability will be scored on a 5-point scale: 1= Completely disagree, 2 = Disagree, 3 = Neither agree nor disagree, 4 = Agree, 5= Completely agree. A higher mean score indicates greater feasibility. The mean score and standard deviation will be reported. However, responses will not be averaged to across items; each item will be analyzed independently.	Up to 60 days
Secondary	Mean score of cancer genomic testing knowledge (Stage 2)	Knowledge of tumor genetic testing adapted from a validated survey from Blanchette, et al.+ select questions from a survey from Rogith, et al.will be utilized to measure the level of cancer genomic testing knowledge. "Don't know" will be scored as incorrect. The proportion of correct responses will be calculated to generate a total score between 0-100, with a higher score indicating greater knowledge. No items will be weighted. Since all items are required, we anticipate missing responses will be rare. Any missing data will be managed case-by-case post-hoc.	Up to 60 days
Secondary	Proportion of participants who select correct response in each genomic testing knowledge instrument item (Stage 2)	Knowledge of tumor genetic testing adapted from a validated survey from Blanchette, et al. including select questions from a survey from Rogith, et al. and is designed to measure the level of cancer genomic testing knowledge. Responses of "Don't know" will be scored as incorrect. Each of the item scores will be reported as a proportion of the participants who answered each item correctly. Since all items are required, we anticipate missing responses will be rare. Any missing data will be managed case-by-case post-hoc.	Up to 60 days
Secondary	Proportion of participants who answer "Yes" to each attitude item in the Attitude and expectations for tumor genetic testing survey (Stage 2)	Attitude and expectations measure for tumor genetic testing is a 17-item measure adapted from a validated survey from Blanchette, et al. including one open-ended investigator-created item. Items on the attitude scoring scale range from "Yes" = 1 and "No" or "Unsure" = 0.	Up to 60 days
Secondary	Proportion of participants who answer "Strongly Agree" or "Agree" to the expectation item in the Attitude and expectations for tumor genetic testing survey (Stage 2)	The attitude and expectations for tumor genetic testing is a measure adapted from a validated survey from Blanchette, et al. and includes one open-ended investigator-created item. The expectations scoring (item 3): "Strongly Agree" or "Agree" = 1 and all other responses = 0	Up to 60 days
Secondary	Participant-reported perspectives of intervention in a semi-structured interview. (Stage 2)	Participant-reported perspectives of intervention in a semi-structured interview will be collected during Stage 1 and reviewed and will be explored using thematic analysis. A codebook will be created using the COM-B ((capability (C), opportunity (O), and motivation (M) / BCW domains (for the secondary objectives) described in the interview guide. This framework provides a systematic approach for identifying behavior change models evaluated according to three criteria: comprehensiveness, coherence, and a clear link to an overarching model of behavior. This will produce evidence-based behavior change techniques most likely to be effective. Emergent codes and themes will be added throughout thematic analysis. Two coders will code each interview (one primary and one secondary coder). Discrepancies will be negotiated to consensus.	Up to 60 days
Secondary	Proportion of participants who have received the tumor genetic pre-test counseling tool who undergo TGT by chart review (Stage 2)	A medical record review of TGT completion date will be conducted. If TGT was not completed, the study staff will review and record reasons for non-completion, and date of last follow-up.	Up to 90 days
