What was measured

Adverse event (AE): any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. Serious AE: an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAE: events that start with onset or worsening (seriousness or severity) dates occurring within the on-treatment periods. TEAEs included both serious and non-serious TEAEs. Related TEAEs are events with relationship missing or related.

Analysis population: SAF included all participants, who were administered any dose of any study intervention. One participant who was randomized to the Placebo + IMRT group but was incorrectly administered a dose of Xevinapant was analyzed in the Xevinapant + IMRT group.

Groups in this outcome

Xevinapant +IMRT

Participants received 3 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 66 Gray (Gy) of intensity modulated radiation therapy (IMRT) in 33 fractions, 2 Gy/fraction, 5 days/week followed by 3 cycles of monotherapy of Xevinapant at a dose of 200 mg/day from Day 1 to 14, per 3-week cycle (Each cycle is of 3 weeks).

Placebo +IMRT

Participants received 3 cycles of oral solution of placebo matched to Xevinapant once daily from Day 1 to 14 per 3-week cycle in combination with with 66 Gray (Gy) of intensity modulated radiation therapy (IMRT) in 33 fractions, 2 Gy/fraction, 5 days/week followed by 3 cycles of monotherapy of placebo matched to Xevinapant from Day 1 to 14, per 3-week cycle (Each cycle is of 3 weeks).
