Abstract 3390
Background
In prior published work, the Worldwide Innovative Network (WIN) Consortium described the Simplified Interventional Mapping System (SIMS) algorithm, based on the hypothesis that both genomic and transcriptomic data are important for matching to a tri-therapy regimen. To account for variation in transcription levels between different tissues, gene by gene tumor RNA levels are normalized against RNA levels in analogous biopsied normal tissue. SPRING is the first trial to assess a SIMS-based tri-therapy regimen in advanced NSCLC.
Methods
Patients with metastatic NSCLC (no EGFR or ALK alterations; no ROS1 alteration if tested; PD-L1 unrestricted; ≤2 prior therapy lines) were treated with avelumab, palbociclib, and axitinib (3 + 3 dose escalation design). After consent, biopsies of tumor and normal endobronchial mucosa were obtained on all patients for analysis on a central genomics/transcriptomics platform and retrospective SIMS algorithm validation. A safety monitoring committee reviews study conduct at least weekly.
Results
Twelve patients have been treated (3 at dose level 1; 6, dose level 2; 3, dose level 3). Three dose-limiting toxicities (DLTs) at least possibly drug related occurred: 1 DLT at dose level 2 (Grade 3 (G3) infusion reaction); 2 DLTs at dose level 3 (G3 hand/foot syndrome and a G5 respiratory failure). The partial response (PR) rate was 44% (4/9 patients who have reached restaging including 2/3 patients at dose level 1; two PRs are in patients who failed prior pembrolizumab). The maximum tolerated dose was avelumab 10 mg/kg IV q2weeks, axitinib 5 mg po bid, palbociclib 75 mg po daily (7 days off; 21 days on) (dose level 2).
Conclusions
The tri-therapy combination of avelumab, axitinib, and palbociclib is tolerable with early evidence of activity including in NSCLC patients who failed a prior checkpoint inhibitor. Expansion cohorts are being added to further explore safety of a recommended phase II dose. Transcriptomic and genomic correlates of response are being assessed.
