An Open-Label Multicenter Phase 1b Study of Tolinapant (ASTX660) in Combination With Radiotherapy/Chemoradiotherapy (RT/CRT) in Preoperative Treatment of Patients With Rectum Cancer (PRAAR 1: Preoperative Radiotherapy And ASTX660 in Rectum Cancer)

Compare two arms:
- Chemotherapy followed by tolinapant (ASTX660) in combination with Long-Course Radio
Chemotherapy (LCRT), and
- Tolinapant (ASTX660) in combination with Short-Course Radiotherapy (SCRT) followed
by chemotherapy For each patient, the treatment arm will be allocated on the
following basis: patients will be allocated to the chemotherapy followed by LCRT arm
unless they present at least one of the following criteria: contraindication to
receive mFOLFIRINOX (including intolerance to irinotecan and UGT1A1*28
polymorphism), age > 75, general condition incompatible with the radiotherapy
schedule of LCRT. In such case, patients will be allocated to the SCRT arm.
Tolinapant (ASTX660) will be administered orally once a day for 7 consecutive days every
other week during 10 weeks (One week On / One week Off during 10 weeks).
Both treatment arms will have a dose escalation part to determine the MTD and/or RP2D,
followed by an expansion part where up to 21 subjects will be dosed at the RP2D. Both
arms will enroll simultaneously.
