Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Sequence 1: Debio 1143 + CRT | Participants received a combination of Debio 1143 along with Chemoradiotherapy (CRT): Radiotherapy +Cisplatin + Xevinapant (Debio 1143). Participants received 6 cycles of oral solution of Xevinapant at a dose of 200 milligrams per day (mg/day) once daily from Day 1 to 14, per 3-week cycle in combination with 70 Gray (Gy) of intensity modulated radiation therapy (IMRT) in 35 fractions, 2 Gy/fraction, over 7 weeks, and High-dose cisplatin (100 mg/m2) on Day 2 of a 3-week cycle per 3 cycles (combination therapy period). If high-dose cisplatin 100 mg/m2 was not tolerated after the first dose, participants could be switched to carboplatin (10mg/mL, iv infusion), followed by 3 cycles of monotherapy of Xevinapant at a dose of 200 mg/day from Day 1 to 14, per 3-week cycle (monotherapy period). | 111 | 364 | EG000 |
| Group 2 | Sequence 2: Placebo + CRT | Participants received a combination of placebo matched to Debio 1143 along with Chemoradiotherapy(CRT): Radiotherapy +Cisplatin+ placebo matched to Xevinapant (Debio 1143). Participants received 6 cycles of oral solution of placebo matched to Xevinapant once daily from Day 1 to 14, per 3-week cycle in combination with 70 Gray (Gy) of intensity modulated radiation therapy (IMRT) in 35 fractions, 2 Gy/fraction, over 7 weeks, and High-dose cisplatin (100 mg/m2) on Day 2 of a 3-week cycle per 3 cycles(combination therapy period).If high-dose cisplatin 100 mg/m2 was not tolerated after the first dose, participants could be switched to carboplatin (10mg/mL, iv infusion), followed by 3 cycles of monotherapy of placebo matched to Xevinapant from Day 1 to 14, per 3-week cycle (monotherapy period). | 93 | 366 | EG001 |

From the EOT visit until the End Of Study visit (Up to 44 months), only All-Cause Mortality, SAEs and late onset Adverse Events of Special Interest were collected
