Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Primary tumor excised by radical inguinal orchiectomy and pathology consistent with GCT (seminoma or NSGCT)
- Clinical stage of patient is either:
- Stage I pure seminoma OR stage I pure seminoma with isolated retroperitoneal relapse or Stage IIA/B pure seminoma
- Stage I NSGCT OR stage I NSGCT with isolated retroperitoneal relapse or Stage IIA/B NSGCT
- For subjects with retroperitoneal lymphadenopathy: no lymph node \>3 cm in greatest dimension with no more than 2 nodes enlarged
- Axial abdominal/pelvic imaging (CT or MRI) and chest imaging (x-ray, CT or MRI) within 3 months of enrollment if stage I patient
- Axial abdominal/pelvic imaging (CT or MRI) and chest imaging (x-ray, CT or MRI) within 8 weeks of enrollment if stage II patient
- miRNA-371 can be drawn and sent for analysis at time of consent
- Enrollment within 1 year after orchiectomy for stage I patients
- Enrollment at any timepoint after orchiectomy for stage II patients
- Retroperitoneal lymphadenopathy must be within an RPLND template
- Biopsy of lymph node is not required, though if biopsy of the retroperitoneal node(s) was obtained, pathology must be consistent with GCT
- Serum Alpha Feto Protein (AFP) \<50 ng/ml, β-Human Chorionic Gonadotropin (β-HCG) 25 mIU/ml within 42 days (6 weeks) of enrollment
- Age ≥ 18 years
- Ability to understand and the willingness to sign a written informed consent
Exclusion criteria
- Second primary malignancy
- Patients receiving any other investigational agent (s)
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Where
- Birmingham, Alabama
- Loma Linda, California
- Los Angeles, California
- New Brunswick, New Jersey
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
