6013 Background: Cetuximab monotherapy results in a median overall survival (OS) of approximately 6 months (mo) in platinum-resistant recurrent/metastatic head and neck squamous cell carcinoma (HNSCC). HNSCC unrelated to human papillomavirus (HPV) is driven by hyperactivation of the CDK4/6 and cyclin D1 (CD1) regulatory complex, resulting in cell cycle progression and tumor growth, suggesting that CDK4/6 inhibition can be a rational therapeutic strategy in this setting. Palbociclib (PAL) is a selective CDK4/6 inhibitor that may reverse cetuximab resistance by countering the actions of deregulated CD1. PAL plus an epidermal growth factor receptor inhibitor synergistically reduced cell viability of HPV-unrelated HNSCC cell lines. In a single-arm, multicenter trial of platinum-resistant, cetuximab-naive, HPV-unrelated HNSCC, PAL in combination with cetuximab resulted in a median OS of 9.5 mo. Methods: In a double-blind randomized phase II trial, patients (pts) with platinum-resistant, cetuximab-naïve, HPV-unrelated HNSCC were treated with cetuximab plus either PAL (arm A) or placebo (arm B). Pts were stratified by performance status (PS) and prior immunotherapy (IT). 120 pts were required for 1:1 randomization to have ≥ 80% power to detect a hazard ratio (HR) of 0.6 (corresponding to a median OS of 10 mo in arm A and 6 mo in arm B) using a 1-sided log-rank test P=0.10). Key secondary endpoints included progression-free survival (PFS), adverse events (AEs), and p16 status. Results: Pts (n=125) were randomized (arm A, 65; arm B, 60). PS and prior IT were balanced between the arms. Median (95% CI) follow-up for OS was 15.9 (15.0–19.4) mo. Median OS was 9.7 (7.3–13.9) mo in arm A and 7.8 (6.7–10.6) mo in Arm B (stratified by PS: HR=0.82 [95% CI, 0.54–1.25], P=0.18). Median PFS was 3.9 mo in arm A and 4.6 mo in arm B (stratified by PS: HR=1.00 [0.7–1.5], P=0.5). Hematologic AEs were more common in arm A. Only 11 pts (9%) received IT after being treated on the trial. Conclusions: Among pts with platinum-resistant, HPV-unrelated HNSCC, PAL plus cetuximab resulted in a trend of prolongation of median OS compared with cetuximab. Clinical trial information: NCT02499120.

Line Setting

666 Background: Anti-VEGF agents plus chemotherapy improve PFS of patients with mCRC in the first- and second-line-setting. During this treatment tumour angiogenesis is driven by other factors but VEGF. Nintedanib, a triple angiokinase inhibitor of VEGFR-1-3, FGFR-1/-3 and PDGFR-α/-β, thereby additionally targets angiogenic escape mechanisms upon resistance to anti-VEGF treatment. The TRICC-C trial evaluates the combination of mFOLFOX6 plus Nintedanib. Final results of the randomized phase II trial are presented. Methods: Patients with mCRC having received one line of non-oxaliplatin containing palliative chemotherapy, with an ECOG-PS of 0/1 were randomized 1:1 in a double-blind design to receive: mFOLFOX6 plus Nintedanib (2 x 200 mg p.o./d, d1-d14) or placebo, respectively, repeated every 14 days. Primary endpoint was PFS. Secondary endpoints were ORR, OS and safety. Patients who received at least one dose of trial medication were included in the efficacy and safety analyses. Results: From 12/2012 to 5/2016 53 patients (scheduled n = 180) were randomized. The trial was terminated prematurely due to slow accrual. Compared to mFOLFOX6 plus placebo (F+P), the combination of mFOLFOX6 plus Nintedanib (F+N) improved mPFS (F+P: 4.6 vs. F+N: 8.1 mo.; HR 0.65; 95% CI 0.32-1.30; p = 0.2156), mOS (F+P: 9.9 vs. F+N: 17.1 mo.; HR 1.03, 95% CI 0.48-2.23; p = 0.9387) and DCR (F+P: 50 vs. F+N: 66,7%; p = 0.2709). ORR was comparable in both arms (F+N: 3.8 vs. F+P: 3.7%). Toxicity was low to moderate without major differences between both arms except G 3/4 neutropenia (F+N: 19%, F+P: 12%) and GI disorders (F+N: 23%, F+P: 15%). Conclusions: Final results suggest a PFS, OS and DCR benefit for mFOLFOX6 + Nintedanib in the second-line therapy of mCRC. Due to the premature termination of the trial there was no statistical significance demonstrable. Showing no clinically significant PFS-benefit in the first-line situation (mFOLFOX6 plus Nintedanib/Bevacizumab, Ann Oncol. 2015) or the last line as single agent, respectively (ESMO 2016) the TRICC-C results suggests that Nintedanib plus mFOLFOX6 could be an interesting therapeutic option for the second-line situation. Clinical trial information: NCT01362361.

7526 Background: In phase II trials in MM, GC on a 21-day (D) schedule has response rates of 16%–26% and median overall survival (OS) of 9.6–13 months (mo). Since VEGF has a key role in MM biology, we added anti-VEGF antibody B to GC in a multi-center, double- blind, placebo-controlled randomized phase II trial. Methods: Eligible pts had unresectable MM; no prior chemotherapy; PS 0–1; no thrombosis, bleeding, or major vessel invasion. Primary endpoint: progression-free survival (PFS). Statistics: 90% power to detect HR 0.57. Stratification: PS (0/1), histology (epithelial/other). G 1,250 mg/m2 D 1, 8 Q21D, C 75 mg/m2 D1 Q21D, and B 15 mg/kg or P D1 Q21D was given × 6 cycles, then B or P Q21D until progression. Baseline plasma VEGF was measured. 115 pts enrolled 12/01- 07/05 at 11 sites, 108 (GCB/GCP) 53/55 were evaluable. Male 74%/84%; median age 62/65 (range 44–78/20–84); PS 1 55%/47%; epithelial 74%/67%; pleural 93%/91%; thrombocytosis 40%/40%. Results: Cycles: total 458/424, median 7/6, range 1–42/2–39. Statistically significantly different (SSD) toxicity (p <0.05), any grade: alopecia 60%/38%; epistaxis 62%/24%; hypertension 45%/22%; non-neutropenic infection 15%/4%; proteinuria 62%/47%; stomatitis 23%/7%. There were no SSD toxicities = grade 3. Median PFS 6.9/6.0 mo (HR 0.93, p=0.88). Median OS 15.6/14.7 mo (p=0.91). 1-year survival 59%/57%. Partial response 25%/22%; stable disease 51%/60%. Median VEGF (N=56) 131/154 pg/ml (range 31–1760/5–1786). Higher VEGF was associated with shorter PFS (p=0.02) and OS (p=0.0066). In pts with VEGF = the median, PFS (p=0.043) and OS (p=0.028) were significantly greater for GCB than GCP; in high VEGF strata this was not SSD. Conclusion: Adding B to GC in MM pts does not yield statistically significant differences in PFS, OS, response, or grade ¾ toxicity. GCB-treated pts with low VEGF levels had longer PFS and OS.
