Advanced Pancreatic Adenocarcinoma

4504 Background: Single-agent gemcitabine (G) remains standard treatment for advanced pancreatic adenocarcinoma (APC). The GIP-1 randomized phase III trial (clinicaltrials.gov ID NCT00813696 ) was performed to compare the combination of cisplatin (P) and G vs. G alone as 1st-line treatment. Methods: Patients (pts) with locally advanced and/or metastatic pancreatic adenocarcinoma, age 18–75, Karnofsky Performance Status (KPS) ≥50, were randomized to receive G (arm A) or G+P (arm B). In arm A, G was administered at 1000 mg/m2 weekly for 7 consecutive wks, and, after a 2-week rest, on day 1, 8, 15 every 4 wks. In Arm B, P 25 mg/m2 weekly (with the exception of day 22) was added to G, same dose used in Arm A (Colucci et al, Cancer 2002; 94:902–10). No maximum number of cycles was planned. Primary endpoint was overall survival (OS). Clinical benefit (CB), objective response rate (ORR), progression-free survival (PFS), toxicity and quality of life were secondary endpoints. To have 80% power of detecting a 0.74 Hazard Ratio (HR) of death (corresponding to increase in median OS from 4.8 to 6.5 months, with bilateral alpha=0.05, 400 pts were planned and 355 deaths were required for final analysis. Results: From April 2002 to April 2007, 400 pts were enrolled (A:199, B; 201) in 46 Italian Institutions. Median age was 63 yrs (range 35–75), 59% were males, 84% stage IV, 83% KPS≥80. After a median follow-up of 38.2 months and 357 deaths, median OS was 8.3 vs 7.2 months in arm A and B, respectively (HR 1.10, 95% CI 0.89–1.35, p=0.38). Median PFS was 3.9 vs 3.8 months in arm A and B, respectively (HR 0.97, 95% CI 0.80–1.19, p=0.80). ORR was 10.1% in arm A and 12.9% in B (p=0.37). CB response was experienced by 23.0% and 15.1% (Arm A vs B, p=0.057). Patients assigned to combination arm experienced more anaemia (all grades: 50% vs 39%, G3: 5% vs 1%), more neutropenia (all grades: 44% vs 36%, G3&4: 25% vs 14%) and more thrombocytopenia (all grades: 57% vs 29%, G3&4: 16% vs 5%). No relevant differences were seen in non-haematological toxicity. Conclusions: Weekly combination of P and G, compared to single-agent G as 1st-line treatment of APC, failed to demonstrate any improvement in OS, PFS, ORR and clinical benefit. No significant financial relationships to disclose.

Advanced Pancreatic Adenocarcinoma

473 Background: Cancer of the exocrine pancreas is a highly lethal malignancy. Based on a phase III study, FOLFIRINOX regimen became the standard first-line treatment for patients with good performance status. However, the optimal management strategy for patients who fail initial FOLFIRINOX remains undefined. We aim at reporting our experience with single-agent gemcitabine as a second-line treatment for advanced pancreatic cancer patients who progressed on FOLFIRINOX. Methods: Patients with advanced exocrine pancreatic adenocarcinoma who received gemcitabine (1.000 mg/m² on days 1, 8 and 15 every 4 weeks) until disease progression, as second-line therapy after FOLFIRINOX failure at our institution were retrospectively evaluated. Progression-free survival (PFS) and overall survival (OS) were estimated by the Kaplan-Meier method. Results: A total of 20 patients were reviewed. Most of them (60%) had metastatic disease while 40% had locally advanced tumors. Median age was 60 years (range 43–74) and 80% were male. Eastern Cooperative Oncology Group (ECOG) performance status was 0 or 1 in 65% and 2 or 3 in 35% of the patients. Median time on prior FOLFIRINOX therapy was 5 months. Median PFS and OS with gemcitabine were 2,0 (95% CI 1,2-2,8) and 5,7 months (95% CI 3,9-7,4), respectively. There were no deaths due to the treatment. Conclusions: In this study, gemcitabine was a reasonable second-line treatment option for patients with advanced pancreatic adenocarcinoma. Phase III trials are urgently needed exploring the role of gemcitabine in the second-line setting.

TPS498 Background: Treatment options are limited for patients with locally advanced unresectable or metastatic urothelial carcinoma (mUC) who progress following prior platinum-based and checkpoint inhibitor (CPI) therapy. Sacituzumab govitecan (SG) is an antibody-drug conjugate consisting of an anti–Trop-2 monoclonal antibody coupled to SN-38 (an active metabolite of irinotecan, a topoisomerase-I inhibitor) via a unique hydrolyzable linker. A phase II registrational study, TROPHY-U-01 study, confirmed the initial positive efficacy signal in mUC. SG demonstrated an objective response rate (ORR) of 27% and median overall survival (OS) of 10.5 months in patients with mUC (median 3 prior lines of therapy and 87% with ≥1 Bellmunt risk factors) who progressed after prior platinum-based and CPI therapies (n=113; Loriot ESMO 2020). The results compared favorably with historic single-agent chemotherapy (ORR ~10%; OS ≤7 months). A phase III trial has been initiated to confirm these findings. Methods: TROPiCS-04 (NCT04527991) is a global, multicenter, open-label, randomized, controlled trial in patients with locally advanced unresectable or mUC who progressed after prior platinum-based and CPI therapies (with Eastern Cooperative Oncology Group performance status 0–1 and adequate hematologic, hepatic, and renal function). Patients will be randomized 1:1 to receive SG 10 mg/kg intravenously (IV) on day 1 and 8 of 21-day cycles or single-agent treatment of physician’s choice (paclitaxel 175 mg/m2, docetaxel 75 mg/m2, or vinflunine 320 mg/m2 IV on day 1 of 21-day cycles) until progressive disease, unacceptable toxicity, or withdrawal of consent. Treatment beyond progressive disease may be permitted in patients deemed to be receiving clinical benefit per investigator assessment. Approximately 482 patients will be enrolled to provide 90% power on the primary endpoint of OS. Secondary endpoints include progression-free survival, ORR, clinical benefit rate, duration of response (all per Response Evaluation Criteria in Solid Tumors v1.1), safety, and quality of life. Study initiation is ongoing and enrollment begins in Q4 2020 across ~90 sites. Clinical trial information: NCT04527991.

TPS2656 Background: ESCC remains the predominant histological subtype of, and accounts for most deaths from, esophageal cancer. PD-1 inhibition has demonstrated antitumor activity and was generally well tolerated in patients (pts) with advanced unresectable or metastatic ESCC. Tislelizumab, an investigational anti-PD-1 antibody, was engineered to minimize binding to FcγR on macrophages to abrogate antibody-dependent phagocytosis, a mechanism of T-cell clearance and potential resistance to anti-PD-1 therapy. Results from early phase clinical studies suggest single-agent tislelizumab was generally well tolerated and had antitumor activity in pts with solid tumors, including ESCC. Methods: This phase 3, randomized, placebo-controlled, double-blind study (NCT03783442) is designed to evaluate the efficacy and safety of tislelizumab plus chemotherapy as first-line treatment of unresectable, locally advanced recurrent or metastatic ESCC. Adult pts with histologically confirmed ESCC that had metastatic disease either at first diagnosis or with a ≥6 month treatment-free interval will be eligible. Additional eligibility criteria include measurable/evaluable disease, ECOG performance score ≤1, and no prior anti-PD-(L)-1, PD-L2, or other first-line therapy or palliative radiation treatment ≤4 weeks before treatment. Approximately 480 pts will be randomized 1:1 to receive investigator-chosen chemotherapy (ICC) plus tislelizumab 200 mg IV Q3W or ICC plus placebo. Chemotherapy options include: platinum (cisplatin 60–80 mg/m2 or oxaliplatin 130 mg/m2 IV Q3W) plus 5-FU 750–800 mg/m2 IV daily for 5 days Q3W; or platinum plus capecitabine 1000 mg/m2 orally BID for 14 days Q3W; or platinum + paclitaxel 175 mg/m2 IV Q3W. Progression-free survival and overall survival are coprimary endpoints; secondary endpoints include objective response rate, duration of response, and health-related quality-of-life. Safety will be assessed by monitoring adverse events, physical examinations, vital signs, and electrocardiograms. This study is actively enrolling. Clinical trial information: NCT03783442.

TPS4595 Background: Lenvatinib (LEN) is a multikinase inhibitor of vascular endothelial growth factor (VEGF) receptor 1–3, fibroblast growth factor receptor 1–4, platelet-derived growth factor receptor alpha, and RET and KIT. Based on a phase 2 study (Motzer et al. Lancet Oncol 2015), LEN was approved in combination with everolimus (EVE) for treatment of metastatic RCC following 1 prior VEGF-targeted therapy. A phase 1b/2 study of LEN in combination with pembrolizumab (PEM) in pts with RCC LEN is also underway. We report the design of a multicenter, open-label, phase 3 trial of LEN plus EVE or PEM vs sunitinib (SUN; a standard therapy for RCC) as first-line treatment for advanced RCC. Methods: Pts aged ≥ 18 years with confirmed advanced RCC diagnosis, ≥ 1 measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, Karnofsky Performance Status ≥ 70, controlled blood pressure, and adequate blood coagulation, renal, hepatic, and bone marrow function are eligible. Pts will be randomized 1:1:1 to receive LEN 18 mg/day + EVE 5 mg/day, LEN 20 mg/day + PEM 200 mg every 3 weeks, or SUN 50 mg/day (on a schedule of 4 weeks on treatment followed by 2 weeks off) until disease progression, unacceptable toxicity, withdrawal of consent, or study end. The primary endpoint is to show superiority of LEN+EVE or LEN+PEM over single-agent SUN as first-line treatment for advanced RCC in improving progression-free survival (PFS). Secondary endpoints include comparison of objective response rate, overall survival, PFS on next-line therapy, health-related quality of life, and safety and tolerability in pts receiving LEN+EVE or LEN+PEM vs SUN. Exploratory endpoints include PFS in the LEN+PEM arm using immune-related RECIST, comparison of duration of response, disease control rate, and clinical benefit rate in pts treated with LEN+EVE or LEN+PEM vs SUN, and analysis of the relationship between blood biomarkers and outcome. No interim analysis is planned for efficacy or futility. Enrollment of 735 pts is planned to achieve 90% power at 2-sided α = 0.05 to detect a difference in ≥ 1 of the primary comparisons. Clinical trial information: NCT02811861.
