About this trial

This study will evaluate the utility of ctDNA detection in patients with high-risk stage I, stage II, and stage III germ cell tumor disease to develop a tool for post-treatment cancer cell detection.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

≥ 18 years old at the time of informed consent

Ability to provide written informed consent and HIPAA authorization

Subjects must have histologically or serologically confirmed seminomatous or non seminomatous germ cell tumor. Non-seminoma includes embryonal carcinoma, choriocarcinoma, yolk sac tumor, or teratoma.

Archival tissue for germ-cell tumor diagnosis available

Disqualifiers

Concurrent disease or condition that would make the subject inappropriate for study participation

Any serious medical disorder that would interfere with the subject's safety

Dementia, altered mental status, or any psychiatric condition that would prohibit the understanding or rendering of informed consent per treating physician coverage.

Patient is being tested for minimal residual disease with other experimental platforms

Trial outcomes

Primary outcomes

1

Positive predictive value (PPV) of circulating tumor DNA in Cohort I

PPV will be calculated as the number of true positives divided by the total number of positive tests in patients with high-risk stage I germ cell tumor.

Time frame
At screening and every 4 months up to 2 years
2

Positive predictive value (PPV) of circulating tumor DNA in Cohort II

PPV will be calculated as the number of true positives divided by the total number of positive tests in the node dissection patients with clinical stage II germ cell tumor.

Time frame
At screening and every 4 months up to 2 years
3

Positive predictive value (PPV) of circulating tumor DNA in Cohort III

PPV will be calculated as the number of true positives divided by the total number of positive tests in the first-line chemotherapy patients with clinical stage III germ cell tumor.

Time frame
At screening and every 4 months up to 2 years

Secondary outcomes

1

Negative predictive value (NPV) of circulating tumor DNA in Cohort I

NPV will be calculated as the number of true negatives divided by the total number of negative tests in patients with high-risk stage I germ cell tumor.

Time frame
At screening and every 4 months up to 2 years
2

Negative predictive value (NPV) of circulating tumor DNA in Cohort II

NPV will be calculated as the number of true negatives divided by the total number of negative tests in the node dissection patients with clinical stage II germ cell tumor.

Time frame
At screening and every 4 months up to 2 years
3

Negative predictive value (NPV) of circulating tumor DNA in Cohort III

NPV will be calculated as the number of true positives divided by the total number of positive tests in the first-line chemotherapy patients with clinical stage III germ cell tumor.

Time frame
At screening and every 4 months up to 2 years
4

Post-node dissection circulating tumor DNA bioassay

Means/stds of ctDNA in both the relapsed and non-relapsed patients in Cohort II.

Time frame
At screening and every 4 months up to 2 years
