E.3 | Principal inclusion criteria |
Participants are eligible to be included in the study only if all the following criteria apply: Age 1. Are ≥ 18 years of age, at the time of signing the informed consent
Type of Participant and Disease Characteristics 2. Have an Eastern Cooperative Oncology Group Performance Status ≤ 1 3. Have histologically confirmed and localized resectable rectal cancer (Stage II or Stage III at original staging). Participants who received induction chemotherapy are allowed to be enrolled to this study except if this induction is resulting in CR or tumor progression. Participants who received induction chemotherapy should be evaluated by MRI, endoscopy and DRE before start of study intervention/randomization (peposertib/placebo and CRT). The following induction chemotherapies prior to screening for the current study are allowed: FOLFOX (folic acid, 5-FU, and oxaliplatin) and CAPEOX (capecitabine and oxaliplatin) as per NCCN 2019 guidance. 4. Have lower edge of the tumor located in rectum 5. Have evaluable disease in MRI 6. Have adequate hematological function: hemoglobin ≥ 9 g/dL, neutrophils ≥ 1.5 × 109/L and platelets ≥ 100 × 109/L 7. Have adequate renal function: serum creatinine ≤ 1.5 × upper limit of normal (ULN) or creatinine clearance ≥ 50 mL/min 8. Have adequate liver function: aspartate aminotransferase, alanine transaminase, alkaline phosphatase ≤ 3 × ULN, and bilirubin ≤ 1.5 × ULN Sex 9. Are male or female Male participants: Agree to the following during the study intervention period and for at least 12 weeks after the last dose of study intervention: o Refrain from donating sperm Plus, either: o Abstain from any activity that allows for exposure to ejaculate. OR o Use a male condom: When having sexual intercourse with a WOCBP, who is not currently pregnant, and advise her to use a highly effective contraceptive method with a failure rate of <1% per year, since a condom may break or leak. When engaging in any activity that allows for exposure to ejaculate. Female Participants: o Are not pregnant or breastfeeding, and at least one of the following conditions applies: Not a WOCBP OR If a WOCBP, use a highly effective contraceptive method (i.e., with a failure rate of <1% per year), preferably with low user dependency, as described for the following time periods: o Before the first dose of the study intervention(s), if using hormonal contraception: Has completed at least one 4-week cycle of an oral contraception pill and either had or has begun her menses OR Has used a depot contraceptive or extended-cycle oral contraceptive for least 28 days and has a documented negative pregnancy test using a highly sensitive assay. AND A barrier method. o During the intervention period o After the study intervention period (i.e., after the last dose of study intervention is administered) for at least 12 weeks, after the last dose of study intervention and agree not to donate eggs (ova, oocytes) for reproduction during this period. The Investigator evaluates the effectiveness of the contraceptive method in relationship to the first dose of study intervention. o Have a negative serum pregnancy test, as required by local regulations, within 4 weeks before the first dose of study intervention. Additional requirements for pregnancy testing during and after study intervention . -The Investigator reviews the medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a female with an early undetected pregnancy.
Informed Consent 10. Can give signed informed consent, which includes compliance with the requirements and restrictions listed in an informed consent form (ICF) and this protocol. |
