Sample Collection for Ongoing Research and Product Evaluation Study

Sample Collection for Ongoing Research and Product Evaluation (SCORE) Study

The SCORE study is a prospective, multi-site clinical trial designed to collect blood and tissue samples, along with relevant clinical data, from participants diagnosed with various solid tumors. The collected specimens and information will be used to evaluate the clinical performance of Natera's molecular residual disease (MRD) testing across multiple cancer types. The study aims to assess the ability of Natera's assays to detect circulating tumor DNA (ctDNA) as a marker for disease recurrence and treatment response.

The study is designed to evaluate the clinical performance of Natera's molecular residual disease (MRD) assays in detecting ctDNA across multiple solid tumor types. The goal is to assess the ability of the assay to identify minimal residual disease, monitor disease recurrence, and evaluate treatment response following standard-of-care therapy. No individual test results from the study testing will be provided to participants or their treating clinicians.

Participants who meet eligibility criteria for the SCORE study will be invited to enroll and must provide written informed consent prior to undergoing any study procedures. Participants will provide study-specific blood samples.

The SCORE study includes three participant cohorts:

• Cohort A - Surgical with Curative Intent
• Cohort B - Neoadjuvant Therapy
• Cohort C - Metastatic/No Surgery

Participants may be followed for up to eight years. During the first three years, blood samples will be collected periodically, approximately every six weeks, for up to two years after surgery or completion of primary treatment. Participants will have data-only follow-up visits at one and five years after the final blood collection.

Tissue Sample Collection Residual tissue samples, collected as part of standard-of-care procedures, will also be obtained for study purposes.
