Radiotherapy Plus Xevinapant in Older Patients With Locally Advanced Head and Neck Squamous Cell Carcinoma
- Conditions
- Locally Advanced Head and Neck Squamous Cell Carcinoma
- Interventions
- Drug: Placebo
- Registration Number
- NCT05724602
- Brief Summary
This is a multicenter, randomized, placebo-controlled, triple blind, phase II study to determine the efficacy and safety of xevinapant with radiotherapy in older patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) of oral cavity, oropharynx, hypopharynx, or larynx.
Upon confirmation of eligibility, subjects will be enrolled and randomized in a 1:1 ratio to:
* Arm A: 3 cycles of xevinapant (200 mg/day from Day 1 to 14, per cycle) + intensive modulated radiotherapy (IMRT) followed by 3 cycles of xevinapant in monotherapy phase (200 mg/day from Day 1 to 14, per cycle)
* Arm B: 3 cycles of placebo (from Day 1 to 14, per cycle) + IMRT followed by 3 cycles of placebo in monotherapy phase (from Day 1 to 14, per cycle).
Patients will be stratified by institution, disease location/p16 status (p16 positive oropharyngeal cancer, versus others), G8 score. Three strata for the G8 will be used (\>14, versus 11-14 versus \<11).
Patients will undergo imaging in week 20 and upon clinical suspicion of progression/recurrence. Clinical examination will take place every 12 weeks in the first 3 years.

Main
- Unknown primary, primary nasopharynx and paranasal sinus.
- Two primaries.
- Any previous or current treatment for invasive head and neck cancer, including induction chemotherapy, surgery, concomitant chemotherapy and cetuximab.
- Gastrointestinal disorders that could affect drug absorption.
- Another malignancy in the previous 3 years with exception of curatively treated disease with no evidence of recurrence.
- Known allergy to xevinapant or any excipient known to be present in active or placebo formulation.
- Active gastrointestinal bleeding, or any other uncontrolled bleeding requiring more than 2 red blood cell transfusions or 4 units of packed red blood cells within 4 weeks prior to enrolment
- Non-Decompensated or symptomatic liver cirrhosis (Child-Pugh score: B or C).
- Impaired cardiovascular function or clinically significant cardiovascular diseases
- Any uncontrolled, intercurrent illness or clinical situation that would in the judgment of investigator, limit compliance with study requirements. This includes but is not limited to uncontrolled active infections, defined as any infection requiring IV antibiotics within 7 days prior to enrolment.

Group Intervention Description Radiotherapy + Placebo Placebo 3 cycles of placebo (from Day 1 to 14, per 21-day cycle) + IMRT followed by 3 cycles of placebo in monotherapy (from Day 1 to 14, per 21-day cycle). Radiotherapy + Xevinapant Xevinapant 3 cycles of xevinapant (200 mg/day from Day 1 to 14, per 21-day cycle) + IMRT followed by 3 cycles of xevinapant in monotherapy (200 mg/day from Day 1 to 14, per 21-day cycle)
- Primary Outcome Measures
Name Time Method Locoregional event-free survival (LREFS) 5 years after first patient in To demonstrate superior efficacy in terms of locoregional event-free survival of xevinapant vs placebo when added to radical radiotherapy in older patients with LA-HNSCC.
- Secondary Outcome Measures
Name Time Method Overall Survival 5 years after first patient in To estimate the added value of xevinapant over RT alone in OS.
Response to treatment by RECIST 1.1 5 years after first patient in To estimate the added value of xevinapant over RT alone in terms of response to treatment.
Progression Free Survival as assessed by the local investigator 5 years after first patient in To estimate the added value of xevinapant over RT alone in PFS.
Safety according to the CTCAE (NCI Common Terminology Criteria for Adverse Events) Version 5.0 for toxicity and Serious Adverse Event reporting 5 years after first patient in To evaluate the frequency and severity of toxicities according to CTCAE v5.0 in the two arms.
HRQOL as assessed by global health/QoL and physical functioning scales at week 20 (Fatigue scale from the Quality of Life Core-30 (QLQ-C30) and pain in the head and neck scale from Item List-225 (IL225)). 5 years after first patient in To assess non-inferiority of xevinapant arm compared to placebo in terms of health-related quality of life (HRQoL) as assessed by the EORTC QLQ-C30 global health/QoL and physical functioning scales.
The questionnaires employ 50 4-point Likert scales with responses from "not at all" to "very much" and two 7-point Likert scales for global health and overall HRQoL. For functional and global HRQoL scales, higher scores represent a better level of functioning and are converted to a 0 to 100 scale. For symptom-oriented scales, a higher score represents more severe symptoms.
