What side effects are associated with this type of intervention?

Common treatments for prostate cancer, including androgen deprivation therapy (ADT), radiation therapy, and chemotherapy, have several known side effects. ADT can lead to hot flashes, reduced libido, fatigue, osteoporosis, and metabolic changes. Radiation therapy may cause urinary symptoms, bowel issues, and erectile dysfunction. Chemotherapy, often used for advanced cases, can result in nausea, hair loss, fatigue, and increased risk of infections. These side effects vary in intensity and duration among patients.

What prior FDA approvals exist?

The FDA has approved several treatments for prostate cancer, including androgen receptor inhibitors like enzalutamide and abiraterone acetate, which are used in metastatic castration-resistant prostate cancer (mCRPC). Additionally, gene expression classifiers such as the Oncotype DX Genomic Prostate Score (GPS) and the Decipher Genomic Classifier (GC) have shown utility in prognostication and guiding treatment decisions, although they are not specifically FDA-approved for this purpose. These classifiers analyze gene expression levels to help stratify patients and inform treatment strategies.

What other types of research exist?

Promising novel alternatives to Gene Expression Classifier for prostate cancer patients include: 1) Urinary-based protein biomarkers identified through advanced multiplex immunoassays and MS-based targeted approaches, which have shown significant promise in initial studies. 2) Immunotherapy options such as PD-1 pathway inhibitors (e.g., pembrolizumab and dostarlimab) for patients with specific genetic markers like dMMR or high TMB. 3) Genomic testing to identify candidates for immune checkpoint inhibitors, which is crucial for determining appropriate treatment plans. These alternatives offer non-invasive and targeted approaches that could enhance treatment decisions in 2024.

Summary

This trial studies how GEC testing can improve prostate cancer care by analyzing gene activity to better predict cancer aggressiveness. It targets prostate cancer patients to help make more informed treatment decisions.

Who is the study for?

This trial is for men 18 or older with newly diagnosed favorable risk prostate cancer, having a PSA level below 20 ng/ml. Participants must have had a diagnostic biopsy within the last 9 months and have available tissue samples. It's suitable for those with Grade Group 1 cancer involving more than two biopsy cores or Grade Group 2 cancer. Men who've already had gene expression classifier testing or any prostate cancer treatment are excluded.

What is being tested?

The G-MAJOR study is evaluating the impact of Gene Expression Classifier (GEC) tests like Prolaris, Decipher, and Oncotype Dx GPS on managing prostate cancer compared to standard care based on askMUSIC scores. The goal is to refine how these genomic tests are used in clinical practice and set up future research.

What are the potential side effects?

Since this trial focuses on genomic testing rather than drug interventions, traditional side effects associated with medications aren't expected. However, there may be some risks related to data privacy and potential emotional impacts from learning about one's genetic risk factors.

Other Research

Prostate cancer treatments primarily target the androgen receptor pathway, which is crucial for prostate cancer cell growth. Androgen deprivation therapy (ADT) reduces androgen levels or blocks androgen receptors, thereby inhibiting cancer cell proliferation. Radiation therapy uses high-energy rays to damage the DNA of cancer cells, leading to cell death. Chemotherapy involves drugs that kill rapidly dividing cells, including cancer cells. Gene expression classifiers, like the ones studied in the Gene Expression Classifier trial, analyze the activity of specific genes to predict how a patient's cancer will respond to these treatments. This personalized approach can help optimize treatment plans, improving outcomes and minimizing unnecessary side effects for prostate cancer patients.
