Abstract 115TiP
Background
In the phase 3 AEGEAN study, neoadjuvant D + platinum-based CT followed by adjuvant D, versus neoadjuvant CT alone, significantly improved pathological complete response (pCR) and event-free survival (EFS) in pts with resectable NSCLC. In the placebo-controlled phase 3 PACIFIC study, consolidation D significantly improved outcomes for pts with unresectable stage III NSCLC after CRT. The strong pathological and clinical outcomes seen with CT + immunotherapy (IO) have generated interest in its use to enable pts with borderline resectable NSCLC to undergo surgery (Sx). In parallel, for pts who are initially deemed resectable but later become unresectable/inoperable during neoadjuvant treatment (Tx), the safety and efficacy of initial neoadjuvant IO + CT, followed by CRT and consolidation IO should be explored. To inform clinical practice, MDT-BRIDGE (NCT05925530) assesses the efficacy and safety of neoadjuvant D + CT followed by either Sx and adjuvant D or CRT and consolidation D in pts with resectable/borderline resectable Stage IIB–IIIB NSCLC.
Trial Design
This is a global, phase 2, non-randomized study of pts aged ≥18 yr with ECOG PS 0/1 and histologically/cytologically confirmed, Tx-naïve, EGFR/ALK wild-type, Stage IIB to select IIIB [N2] NSCLC (AJCC 8th ed). Initially deemed resectable/borderline resectable by a multidisciplinary team (MDT), ∼140 pts will receive 2 cycles of neoadjuvant D + investigator’s choice platinum-based CT Q3W IV, followed by MDT assessment of resectability. Pts deemed resectable will receive a further 1–2 cycles of neoadjuvant D + CT followed by Sx (Cohort 1); pts deemed unresectable will receive CRT for ∼6 wk (Cohort 2). Pts in Cohort 1 who become ineligible for Sx can enter Cohort 2. After Sx/CRT, all pts will receive D Q4W IV for up to 1 yr. The primary endpoint is the resection rate in all pts. Secondary endpoints include resection rates in the subsets of pts deemed resectable or borderline resectable at baseline; R0, R1, and R2 resection outcomes; pCR; EFS; progression-free survival; overall survival; objective response rate; ctDNA clearance; and safety.
