6001 Background: Locally advanced HNSCC is treated curatively, but recurrence is common. In HNSCC, EGFR is richly expressed and EGFR inhibition is validated treatment (tx); the ErbB family blocker afatinib (A) showed efficacy in recurrent/metastatic disease. This Phase III trial assessed if A after definitive CRT improves disease-free survival (DFS). Methods: Eligible pts had complete response after CRT ≥66 Gy (or equivalent) with concurrent cisplatin or carboplatin but not prior EGFR inhibition, for HNSCC of oral cavity, hypopharynx, larynx, or oropharynx with >10 pack years (pk yrs) tobacco use. Pts were stratified by ECOG PS (0/1) and nodal stage (N0–2a/N2b–3), and randomized 2:1 to A 40 mg/d or placebo (P); tx continued for 18 m if tolerated, or until disease recurrence. The primary endpoint was DFS. Results: Of 669 pts planned, 617 were randomized; A 411, P 206. Median age was 58 yrs; 86% were male; 65% ECOG PS 0; most had smoked (A/P ex-smoker: 66/72%; current: 28/22%). Subsites (A/P) were: oropharynx 53/54%; hypopharynx 21/23%; larynx 18/12%; oral cavity 9/10%. The majority had T3 or 4 (A/P 70/68%) and N2 disease (67/63%). Accrual was halted for futility on independent DMC recommendation: at a pre-planned interim analysis (40% of DFS events), median DFS was A 43.4 m vs P not reached (NR; HR 1.13 [95% CI 0.81–1.57], p=0.48); the Table shows key subgroups. Median treatment duration was A 300.0 d, P 455.5 d. Recurrence was A 23%, P 23%. Dose reduction of A was required in 53% (mostly due to diarrhea, stomatitis). Tx was discontinued due to AEs in A 15%, P 4%. Conclusions: A after CRT did not improve DFS vs P. Subgroup analyses were underpowered to provide definitive conclusions. Harrington and Cohen contributed equally. Clinical trial information: NCT01345669. [Table: see text]

TPS5599 Background: Locally advanced squamous cell cancer of the head and neck (SCCHN) is treated with curative intent, but recurrence and death are common. SCCHN frequently over-expresses EGFR (ErbB1). Co-expression of other HER family members such as HER2 (ErbB2) may contribute to resistance to EGFR inhibition, which is the only validated targeted therapy in SCCHN. Methods: The trial investigates if adjuvant afatanib, an irreversible ErbB family blocker, which has shown preclinical activity against all ErbB dimers including EGFR and HER2, reduces the risk of recurrence in high-risk patients who have no evidence of disease following platinum-based chemoradiation with or without neck dissection. Patients are eligible who have received definitive chemoradiation to a minimum of 66 Gy, with concurrent cisplatin (≥200 mg/m2) or carboplatin (≥AUC 9), for SCC of the oral cavity, oropharynx, or hypopharynx or larynx. Patients with base of tongue or tonsil cancer and ≤10 pack years of tobacco use, as well as those with nasopharynx, sinus or salivary gland cancer, are excluded. Adequate bone marrow, liver and kidney function is required. Prior therapy with investigational agents or EGFR inhibitors is not permitted. Randomization must take place within 16 weeks of the completion of chemoradiation with or without subsequent neck dissection. Patients are randomized 2:1 to afatinib 40 mg po qd or placebo, and treatment continues for 18 months in the absence of disease recurrence, second primary tumors, or intolerance to the study medication. Dose escalation to 50 mg qd is undertaken in patients with no side effects, and stepwise dose reduction to 30 or 20 mg po qd for diarrhea, skin toxicity or other adverse events is permitted. The primary endpoint is disease-free survival (DFS). The study is planned to accrue approximately 669 patients worldwide, with a 90% power to detect a hazard ratio of 0.72. Secondary endpoints are DFS at 2 years, overall survival, health-related quality of life, and safety.

Abstract   In recent years, immune checkpoint inhibitors (ICIs) have shown promising results in the treatment of ESCC. More than 20 phase II clinical trials have been launched to explore combinations of ICIs in the neoadjuvant setting for ESCC. Based on our phase II clinical trial, a two-arm phase III trial was launched in our Hospital. Methods A two-arm phase III trial was launched in April 2020 in our Hospital. Patient recruitment will be completed within 18 months. The primary endpoint is event-free survival (EFS). The secondary endpoints include pathologic complete response (pCR), disease-free survival (DFS) rate, overall response rate (ORR), R0 resection rate, major pathologic response (MPR), adverse events (AEs), complication rate and quality of life (QOL). A biobank of pretreatment, resected tumor tissue and paired blood samples will be built for translational research in the future. Results Until Dec. 2021, one hundred and twenty ESCC patients recruited in the trial. The trial is ongoing. Conclusion This RCT directly compares NAC with neoadjuvant toripalimab plus chemotherapy in terms of EFS for locally advanced ESCC. The results may usher in a new era of resectable ESCC treatment.

4014 Background: 5-FU based CRT is regarded standard perioperative treatment in LARC. Here we report safety data of a non-inferiority phase III trial investigating (neo-)adjuvant CRT with Cape in comparison with 5-FU. Methods: Patients (pts) aged ≥18 years with LARC UICC stages II or III were recruited in this two-arm, two-strata randomized phase-III trial (arm A: Cape, arm B: 5-FU; stratum [S] I: adjuvant, S II: neoadjuvant). Regimens: Arm A: CRT: 50.4 Gy + Cape 1,650 mg/m2 days 1–38 plus five cycles of Cape 2,500 mg/m2 d 1–14, rep. d 22 (S I: 2 x Cape, CRT, 3 x Cape; S II: CRT, TME surgery followed by Cape x 5). Arm B: CRT: 50.4 Gy + 5-FU 225 mg/m2 c.i. daily [S I] or 5-FU 1,000 mg/m2 c.i. d 1–5 and 29–33 [S II] plus 4 cycles of bolus 5-FU 500mg/m2 d 1–5, rep. d 29 (S I: 2 x 5-FU, CRT, 2 x 5-FU; S II: CRT, TME surgery followed by 5-FU x 4). Primary endpoint was survival, secondary endpoints comprised safety and disease-free survival. Results: Of 401 randomized pts a total of 392 are evaluable (Arm A n=197, arm B n=195; S I n=231, S II n=161). Both arms were well balanced with respect to age, sex, WHO status, T- and N- stages. Regarding duration of treatment, 78% (Cape) and 80% (5-FU) completed all scheduled treatment cycles in S I, and 46% (Cape) and 40% (5-FU) in neoadjuvant stratum S II. In S II a total of 38% (Cape) and 43% (5-FU) did not continue chemotherapy after tumour resection. Concerning early efficacy endpoints in S II, pts treated with Cape (evaluable thus far n=121) exhibited a higher rate of T-downstaging (defined as ypT0–2; 52 vs 39%; p=0.16) and N0 (71 vs 56%; p=0.09). Regarding overall safety (NCI-CTC), pts receiving Cape experienced significantly less leukopenia (25 vs 35%; p=0.04), but more hand-foot syndrome (31 vs. 2%; p<0.001). Stomatitis/mucositis, diarrhea, nausea/vomiting, and radiodermatitis were not significantly different between both arms. Conclusions: Given the observed safety profile and the trend in improved downstaging in neoadjuvant stratum, Cape exhibits a potential to replace 5-FU as perioperative treatment of LARC. Efficacy results on the primary endpoint are expected for 2010. [Table: see text]

5571 Background: We report the impact of p16 status on quality of life (QOL) for patients with stage III or IV (excluding T1-2N1 and M1) squamous cell carcinoma of the oropharynx (OPC) treated with concurrent chemoradiotherapy in a large international phase III trial (TROG 02.02/HeadSTART). Methods: The 861 patients accrued received definitive radiotherapy (RT) (70 Gy/7 weeks) concurrently with 3 cycles of either cisplatin (100mg/m2) or cisplatin (75 mg/m2) plus tirapazamine (290 mg/m2/day) by random assignment, as previously described. QOL was measured with the FACT-H&N at baseline, 2,6,12, 23 and 38 months. No significant difference in overall or subscale QOL score change from baseline was observed between arms at any subsequent time point; results for the oropharynx subgroup by p16 status are reported for both treatment arms combined. Results: Of 853 eligible participants, 465 had OPC, for whom p16 status could be determined in 206. Of 179 who received adequate RT (≥ 60 Gy, no major deviations) and completed baseline QOL, 104 were p16+ and 79 were p16-. p16+ patients had better baseline ECOG PS, lower T-category, higher N-category, were younger and were less likely to be current smokers. Baseline mean FACT-H&N score was statistically and clinically significantly better in p16+ patients (111 vs. 102, p=0.001). The drop in QOL from baseline to 2 months was more severe in p16+ cases (-20.4 vs -9.1, p=0.001), resulting in an equalization of 2 month scores (p16+: 90.6, p16-: 93.6, p=0.16). At 6 and 12 months post-treatment, no difference in score changes from baseline by p16 status was seen (6 mo, p16+: -6.2, p16 -:-1.2, p=0.22; 12 mo, p16 +: -0.3, p16 -: +2.0, p=0.82). Conclusions: p16 associated oropharyngeal cancer has been shown to be a distinct entity with different demographic features. In our study, such patients exhibited better baseline QOL and a more severe drop immediately after treatment, but did not differ in long-term QOL response to the effects of aggressive concurrent chemoradiation. Given the favorable prognosis of p16-associated oropharyngeal cancer, efforts to reduce the QOL burden of treatment are warranted.
