Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Diagnosis, Therapy, Efficacy
To investigate whether the disease-free survival in patients with rectal cancer who have
detectable ctDNA after primary tumour resection, can be improved by administration of
adjuvant chemotherapy
Secondary objectives 6
- To investigate whether overall survival of rectal cancer patients with detectable ctDNA after surgery can be improved with adjuvant chemotherapy
- To compare all (eligible) patients in the control group to patients in the experimental group who actually started the adjuvant chemotherapy by a per protocol analysis (for pure treatment effect) for disease-free and overall survival.
- To compare the effect of adjuvant chemotherapy on quality of life.
- To compare the disease-free survival of patients with detectable ctDNA but without receiving adjuvant chemotherapy with patients with undetectable ctDNA.
- To compare the clearance of ctDNA of the patients who received adjuvant chemotherapy in the experimental group with the patients in the control group.
- To investigate the co-occurrence of ctDNA in peripheral blood at the timing of detection of recurrent disease on imaging.

Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 8
- Age ≥ 18 years
- WHO performance score 0-1
- Informed consent for PLCRC with specific consent for additional blood withdrawals and offering of future experimental research
- Informed consent for the REACT trial
- Histological confirmed rectal cancer; either treated with neoadjuvant (chemo)radiotherapy, and/or clinical T4 and/or N+ in case no neoadjuvant therapy was administered
- Eligible to receive treatment with combination adjuvant chemotherapy (CAPOX/FOLFOX) according to the treating physician.
- Mentally competent and able to read and understand Dutch language.
- Detectable ctDNA in the postoperative blood sample
Exclusion criteria 11
- Another malignancy in previous 5 years, with the exception of treated carcinoma in situ or skin cancer other than melanoma
- Current or recent (within 28 days prior to randomisation) treatment with another investigational drug or participation in another investigational study.
- Incomplete primary tumour resection (R1 or R2 resection)
- Contra-indication for fluoropyrimidines or oxaliplatin
- Neoadjuvant oxaliplatin based systemic treatment, e.g. treated with the RAPIDO regimen consisting of short course radiotherapy followed by 6 cycles of CAPOX or 9 cycles of FOLFOX prior to surgery
- Patients with a clinical complete response, who will not undergo surger
- Pregnant and lactating women
- History of psychiatric disability judged by the investigator to be clinically significant, precluding informed consent or interfering with compliance of the intervention group
- Serious concomitant systemic disorders that would compromise the safety of the patient or his/her ability to complete the study, at the discretion of the investigator
- Serious infections (uncontrolled or requiring treatment)
- Metastatic disease
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- disease-free survival in the intention-to-treat population
Secondary endpoints 6
- Disease-free survival
- Overall survival
- Quality of life
- In addition to intention-to-treat analysis to estimate the effect size, also a per-protocol analysis (for pure treatment effect) will be carried out for disease-free survival and overall survival
- The results of the ctDNA analysis of the blood samples taken at the first follow-up of the randomised patients who were ctDNA positive after surgery will be compared between the patients who received adjuvant chemotherapy and those who did not.
- Within the group of patients with de-tectable ctDNA after surgery, the pro-portion of patients with detectable ctDNA in the peripheral blood at the timing of detection of recurrent dis-ease on imaging will be assessed.
