Molecular Residual Disease in Solid Tumors: A Prospective Study to Collect Clinical Data and Biospecimens to Support Discovery and Development of Cancer Biomarkers

Observational Paradigm Health · NCT06605404

This study is collecting blood and tissue samples from patients with certain types of cancer to see if it can help improve how we detect cancer and understand the risk of it coming back.

What this trial studies

This observational study aims to gather clinical information, blood, and tumor tissue samples from participants diagnosed with stage I, II, or operable stage III cancers, including muscle invasive bladder cancer, esophageal cancer, gastric and gastroesophageal junction adenocarcinoma, melanoma, and non-small cell lung cancer. Participants will receive standard care from their healthcare providers while contributing to the study over approximately 5.5 years. The collected data will be utilized to develop tests that enhance cancer detection and assess the risk of recurrence.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a confirmed diagnosis of specific solid tumors eligible for curative intent therapy.

Not a fit: Patients who have received systemic therapy for their current cancer diagnosis prior to enrollment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved methods for detecting cancer and understanding its recurrence risk.

How similar studies have performed: Other studies focusing on biospecimen collection and observational data have shown promise in improving cancer detection and treatment strategies.

Eligibility criteria

Eligibility Criteria:

1. Age 18 years or older.
2. Confirmed histological or cytological diagnosis of a malignant solid tumor that is either specified in one of the pre-defined tumor cohorts or meets the enrollment criteria for the Mix of Solid Tumors (MOST) cohort (Table 1).
3. Eligible for curative intent therapy, with surgical resection of cancer planned.

   a. If surgical resection has occurred, enrollment should occur within 3 months of surgical resection and before initiation of adjuvant therapy.
4. Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0, 1, or 2.
5. No systemic therapy for current cancer diagnosis administered before enrollment.
6. Willing and able to comply with required study procedures, including blood sample collection and primary tumor tissue submission from diagnostic biopsy or surgical excision.
7. Has completed all therapy (including endocrine therapy) 3 or more years ago for any previous invasive solid organ malignancy (with exception of nonmelanoma skin cancers) or hematologic malignancy. Individuals with a prior history of noninvasive (in situ) carcinomas may participate if they have received definitive treatment (no washout period required).
8. No concurrent diagnosis of another invasive cancer, except for nonmelanoma skin cancers.
9. No prior allogeneic hematopoietic stem cell transplant.
