Development of a Cell Free DNA Assay as a Biomarker for Predicting Early Non-response to Therapy in Metastatic Cancer

Completed

Conditions studied: Metastatic Non-Small Cell Lung Carcinoma, Metastatic Colorectal Cancer, Metastatic Breast Cancer

In brief

Accrue samples for the further development and clinical validation of a blood-based cell-free DNA (cfDNA) quantitative real-time polymerase chain reaction (qPCR) assay as a potential biomarker for early non-response to therapy in stage IV non-small cell lung cancer (NSCLC), colorectal cancer (CRC) and breast cancer (BC).

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥ 18 years.
• Documented stage IV NSCLC, SCLC, BC or CRC (can be new diagnosis, persistent or recurrent disease):
• BC patients who meet the following criteria:
• ER+/HER2- and has failed hormone therapy within the last two years, or ER+/HER2+ or, ER-/HER+ or, HER2-/ER-/PR- (TNBC), and Has ≥ 1 measurable non- bone lesion as measured per RECIST or, If bone only disease, has two or more measurable (> 1 cm by RECIST) predominantly lytic bone lesions
• Planned initiation of new systemic first- or second-line treatment or subsequent therapies with chemotherapy, immunotherapy, targeted therapy or combination thereof. Or continuation of the current line of therapy after RECIST/iRECIST evaluation which coincides with end of the cycle of therapy and prior to initiation of the next cycle of therapy.
• Imaging to determine RECIST and/or iRECIST criteria:
• If baseline blood draw is planned prior to first cycle of a line (1st, 2nd, 3rd etc) of therapy, measurable disease with CT or MRI or PET/CT monitoring should be completed within 4 weeks prior to baseline blood draw.
• If baseline test is performed at the completion of a cycle of therapy, CT or MRI or PET/CT monitoring should be completed to coincide with end of cycle of therapy and prior to baseline blood draw.
• Planned CT or MRI or PET/CT monitoring for treatment response completed within 8-12 weeks of start of treatment.
• Willing and able to donate up to 30mL of blood at each blood draw. Willing and able to provide informed consent.

You may not qualify if…

• Diagnosis of a secondary malignancy that is not in complete remission. Imaging to determine RECIST and/or iRECIST criteria is not planned or available.
• CT or MRI or PET/CT monitoring for treatment response is not planned within 8-12 weeks.
• Presence of active autoimmune disease which is under active treatment. DVT, PE, sepsis, or has recovered from any other serious illness within the prior 2 weeks of the baseline blood draw. (Note: Patients who have recovered from similar conditions more than 2 weeks prior to the baseline blood draw would be eligible for the study) If initiating a new line of therapy, patient has received any doses of the new block of therapy before the first designated blood draw.
• If continuing current line of therapy after CT, MRI or PET/CT monitoring, patient has received subsequent cycle of therapy before the first designated blood draw.
• Performance status ECOG ≥3. Evidence of acute renal failure as determined by current clinical guidelines. NSCLC, SCLC or CRC patients beyond 9 months of the initiation of therapy, on 1st line immunotherapy alone, or combination immunotherapy and chemotherapy regimens. (Note: patients on subsequent lines of therapy (2nd,3rd line etc.) would be eligible at any time point including prior to the 9 months vs those patients on 1st line therapy)..
