LBA52 Sintilimab plus chemotherapy versus chemotherapy as first-line therapy in patients with advanced or metastatic esophageal squamous cell cancer: First results of the phase III ORIENT-15 study

4097 Background: The aim of this present phase II study is to explore the safety and efficacy of paclitaxel (T), cisplatin (C), and nimotuzumab (N), a humanized anti-EGFR monoclonal antibody combination (TCN) as first-line treatment in advanced esophageal squamous cell cancer (ESCC). Methods: Patients with histologically confirmed advanced ESCC, measureable tumor, and no prior chemotherapy and radiotherapy except adjuvant treatment were enrolled. Patients were given cisplatin 60mg/m2, paclitaxel 175mg/m2per 21 days for at least 2 cycles. The nimotuzumab was given 200mg weekly. Radiotherapy was admitted for patients with unresectable local advanced disease after 4 cycle of TCN treatment. The primary endpoints were safety and objective response rate (ORR). The secondary endpoints were progression-free survival (PFS) and over-all survival (OS). The expression of EGFR and ERCC1 were also analyzed by histoimmunochemical staining. Results: Between Mar. 2011 and Dec. 2012, 55 patients with advanced ESCC were enrolled and 53 (96.4%) were eligible for evaluation. The ORR was 54.7% (29/53) and the DCR was 94.3% (50/53). The expression of EGFR and ERCC1 were detected in 46 and 31 patients respectively. The ORR had no relation to both the expression of EGFR (55.3% vs 62.5%, p=0.71) and ERCC1 (41.7% vs 58.3%, p=0.47). As a median follow-up of 15months, the median PFS was 10.5 months (95% CI 8.7 to 12.3 months).The TCN combination treatment was well tolerated and the most common adverse events were alopecia (86.8%), leukopenia (84.9%), anorexia (84.9%), vomiting (73.6%), fatigue (73.6%), pain (66.0%), and anaemia (39.6%). And 18 (34%) patients had Grade 3 to 4 leukopenia. The median OS have not yet been reached. Conclusions: In this study, the ORR, DCR and PFS are superior to previous published studies. The addition of anti-EGFR treatment of nimotuzumab to standard chemotherapy was well tolerated with no serious AEs. But the expression of EGFR by IHC could not predict the outcome of nimotuzumab treatment. A phase III study of TCN followed by radiotherapy in unresectable local advanced ESCC had been designed to explore the survival benefits. Clinical trial information: NCT01336049.

PURPOSE: On the basis of the activity of paclitaxel as a single agent in chemotherapy-naive squamous cell carcinoma of the cervix in a prior Gynecologic Oncology Group (GOG) trial, a phase II study of paclitaxel and cisplatin as first-line therapy was conducted by the GOG. PATIENTS AND METHODS: Eligibility included squamous cell cancer of the cervix not curable by surgery or radiation, measurable disease, WBC count ≥ 3,000/μL, platelet count ≥ 100,000/μL, serum creatinine ≥ 2 mg/100 mL, and adequate hepatic function. The starting dose was paclitaxel 135 mg/m2 infused over 24 hours followed by cisplatin 75 mg/m2 every 21 days. On the basis of toxicity, a dose escalation of paclitaxel to a maximum dose of 170 mg/m2/d was prescribed. RESULTS: Forty-seven patients were enrolled onto this study; 44 patients were assessable for toxicity and 41 for response. Forty (90.9%) had received prior radiation therapy. A median of six courses of chemotherapy was given (range, one to 10 courses). Neutropenia grade 3 (15.9%) and 4 (61.4%) was the most frequent severe adverse effect and was associated with fever in 13 patients (27.7%). Two patients (4.5%) died from neutropenic sepsis. Grade 4 thrombocytopenia occurred in 6.8% of patients. Of 41 assessable patients, five (12.2%) had complete responses and 14 (34.1%) had partial responses for an overall response rate of 46.3% (95% confidence interval, 30.7% to 62.6%). The median progression-free interval, was 5.4+ months (range, 0.3 to 22+ months) with a median survival of 10.0+ months (range, 0.9 to 22.2 months). Response was more frequent in patients with disease in nonirradiated sites (70% v 23%, P = .008). CONCLUSION: This regimen seems highly active in advanced and recurrent squamous cell carcinoma of the cervix and is currently being evaluated by the GOG in a phase III randomized study comparing the combination of paclitaxel and cisplatin with cisplatin alone.
