Une étude exploratoire à deux bras (phase 2) sur le nivolumab en monothérapie ou en association avec le nab-paclitaxel et le carboplatine dans le CPNPC à un stade précoce en Chine
Le nivolumab (BMS-936558) est un mAb d'isotype IgG4 (kappa) entièrement humain qui se lie à PD-1 sur les cellules immunitaires activées et perturbe l'engagement du récepteur avec ses ligands PD-L1 (B7 H1/CD274) et PD-L2 (B7 -DC/CD273), supprimant ainsi les signaux inhibiteurs et augmentant la réponse antitumorale de l'hôte. Dans les premiers essais cliniques, le nivolumab a démontré une activité dans plusieurs types de tumeurs, notamment le mélanome, le carcinome à cellules rénales (RCC) et le cancer du poumon non à petites cellules (NSCLC).
Le nivolumab est en développement clinique pour le traitement des patients atteints de NSCLC, de RCC, de mélanome, de carcinome épidermoïde de la tête et du cou (SCCHN) et d'autres tumeurs (par exemple, glioblastome multiforme, mésothéliome, cancer du poumon à petites cellules, gastrique).
Le nivolumab est approuvé aux États-Unis (É.-U.), dans l'Union européenne et dans d'autres pays pour le traitement des patients atteints de mélanome non résécable ou métastatique, de CPNPC avancé avec progression sous ou après une chimiothérapie à base de platine, de RCC avancé dont la maladie a progressé sous traitement antiangiogénique, Lymphome hodgkinien classique qui a rechuté ou progressé après une greffe autologue de cellules souches hématopoïétiques et un traitement post-greffe au brentuximab védotine, et carcinome épidermoïde récurrent ou métastatique de la tête et du cou avec progression de la maladie pendant ou après un traitement à base de platine.
L'étude proposée évaluera l'efficacité et l'innocuité de l'administration préopératoire de Nivolumab ou de Nivolumab combiné avec du nab-paclitaxel et du carboplatine en situation néoadjuvante et de l'administration de Nivolumab en situation adjuvante chez des patients atteints d'un CPNPC résécable à haut risque, et facilitera une caractérisation exploratoire complète de le microenvironnement immunitaire tumoral et les cellules immunitaires circulantes chez ces patients. Les données obtenues dans cette étude fourniront des informations précieuses pour planifier d'autres essais cliniques prospectifs d'anti-PD-1 et d'autres immunothérapies dans le NSCLC, à la fois dans le cadre de la maladie périopératoire et avancée. A terme, il est hautement souhaitable de découvrir des biomarqueurs prospectifs de réponse et de toxicité pour permettre aux patients atteints de NSCLC les plus susceptibles d'en retirer un bénéfice de recevoir un traitement anti-PD-1, et inversement de minimiser le risque de toxicité et de traitement inefficace pour les patients peu susceptible d'en bénéficier.

Expérimental: Part 3: Real-world cohort
Part 3 aims to evaluate the real-world effectiveness of neoadjuvant chemoimmunotherapy in patients with EGFR/ALK wild-type, potentially resectable or unresectable Stage III NSCLC. Treatment Paradigm: Eligible subjects will receive 3 cycles of neoadjuvant chemoimmunotherapy. Subsequently, a Multidisciplinary Team (MDT) will evaluate and determine the optimal definitive local therapy, triage patients to either radical resection or concurrent chemoradiotherapy (CCRT). Following the completion of local therapy, patients will receive adjuvant or consolidation immunotherapy for a duration of 1 year, administered every 3 weeks (Q3W). Sample Size: The planned enrollment for Part 3 is 215 patients. |
